For large archives, I want to display a progress bar while the archive
is being extracted with:
https://docs.python.org/3/library/tarfile.html#tarfile.TarFile.extractall
I could write my own version of extractall() to do this, or maybe we
could introduce a callback option that gets called
everytime .extract() is called in extractall()
The callback can receive the tarinfo object and where it's being
extracted. This is enough to plug a progress bar
and avoid reinventing .extractall()
This is not enough if extract large files. In that case you perhaps want
to update the progress bar more often.
If add this feature to tarfile, it may be worth to add it to zipfile and
shutil functions (copytree, rmtree). And if call a callback for every
extracted/copied entity, it may be worth to use its result for filtering.
