GH-107465: Add `pathlib.Path.from_uri()` classmethod. by barneygale · Pull Request #107640 · python/cpython

barneygale · 2023-08-04T17:42:18Z

This method supports file URIs (including variants) as described in RFC 8089, such as URIs generated by pathlib.Path.as_uri() and urllib.request.pathname2url().

The method is added to Path rather than PurePath because it uses os.fsdecode(), and so its results vary from system to system. I intend to deprecate PurePath.as_uri() and move it to Path for the same reason.

Thanks for your feedback, both. I've revised the code: Path.from_uri() now raises ValueError if the URI does not begin with file:, or if it encodes a relative path.

We could add a non-strict mode, but I think that's best done in a separate PR that also considers to_uri().

Thanks!

Note: switching to '15de493395c3251b8b82063bbe22a379792b9404'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 15de493395 GH-107465: Add `pathlib.Path.from_uri()` classmethod. (#107640)
Switched to and reset branch 'main'

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

make: *** [Makefile:2020: buildbottest] Error 5

…07640) This method supports file URIs (including variants) as described in RFC 8089, such as URIs generated by `pathlib.Path.as_uri()` and `urllib.request.pathname2url()`. The method is added to `Path` rather than `PurePath` because it uses `os.fsdecode()`, and so its results vary from system to system. I intend to deprecate `PurePath.as_uri()` and move it to `Path` for the same reason. Co-authored-by: Adam Turner <9087854+AA-Turner@users.noreply.github.com>
