* [3.12] gh-105002: [pathlib] Fix relative_to with walk_up=True using ".." ↵Miss Islington (bot)2023-07-261-0/+12
| | | | | | | | | | | (GH-107014) (#107315) gh-105002: [pathlib] Fix relative_to with walk_up=True using ".." (GH-107014) It makes sense to raise an Error because ".." can not be resolved and the current working directory is unknown. (cherry picked from commit e7e6e4b035f51ab4a962b45a957254859f264f4f) Co-authored-by: János Kukovecz <kukoveczjanos@gmail.com>
* [3.12] GH-106330: Fix matching of empty path in `pathlib.PurePath.match()` ↵Barney Gale2023-07-041-0/+4
| | | | | | | | (GH-106331) (GH-106372) We match paths using the `_lines` attribute, which is derived from the path's string representation. The bug arises because an empty path's string representation is `'.'` (not `''`), which is matched by the `'*'` wildcard. (cherry picked from commit b4efdf8cda8fbbd0ca53b457d5f6e46a59348caf)

* GH-102613: Fix recursion error from `pathlib.Path.glob()` (GH-104373)Barney Gale2023-05-151-0/+11
| | | | Use `Path.walk()` to implement the recursive wildcard `**`. This method uses an iterative (rather than recursive) walk - see GH-100282.
* GH-90208: Suppress OSError exceptions from `pathlib.Path.glob()` (GH-104141)Barney Gale2023-05-111-26/+12
| | | | | | | | | | | `pathlib.Path.glob()` now suppresses all OSError exceptions, except those raised from calling `is_dir()` on the top-level path. Previously, `glob()` suppressed ENOENT, ENOTDIR, EBADF and ELOOP errors and their Windows equivalents. PermissionError was also suppressed unless it occurred when calling `is_dir()` on the top-level path. However, the selector would abort prematurely if a PermissionError was raised, and so `glob()` could return incomplete results.
* GH-87695: Fix OSError from `pathlib.Path.glob()` (GH-104292)Barney Gale2023-05-101-0/+9
| | | | Fix issue where `pathlib.Path.glob()` raised `OSError` when it encountered a symlink to an overly long path.
* GH-102613: Improve performance of `pathlib.Path.rglob()` (GH-104244)Barney Gale2023-05-071-1/+5
| | | | | | | | | | Stop de-duplicating results in `_RecursiveWildcardSelector`. A new `_DoubleRecursiveWildcardSelector` class is introduced which performs de-duplication, but this is used _only_ for patterns with multiple non-adjacent `**` segments, such as `path.glob('**/foo/**')`. By avoiding the use of a set, `PurePath.__hash__()` is not called, and so paths do not need to be stringified and case-normalised. Also merge adjacent '**' segments in patterns.

* GH-100479: Add `pathlib.PurePath.with_segments()` (GH-103975)Barney Gale2023-05-051-15/+37
| | | | | Add `pathlib.PurePath.with_segments()`, which creates a path object from arguments. This method is called whenever a derivative path is created, such as from `pathlib.PurePath.parent`. Subclasses may override this method to share information between path objects. Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>
* GH-81079: Add case_sensitive argument to `pathlib.Path.glob()` (GH-102710)Barney Gale2023-05-041-0/+12
| | | | | | This argument allows case-sensitive matching to be enabled on Windows, and case-insensitive matching to be enabled on Posix. Co-authored-by: Steve Dower <steve.dower@microsoft.com>

| | | | | | | | (GH-104103) These segments do not require a `stat()` call, as the selector's `_select_from()` method is called after we've established that the parent is a directory.

| | | | | | | | Check that arguments are strings before calling `os.path.join()`. Also improve performance of `PurePath(PurePath(...))` while we're in the area: we now use the *unnormalized* string path of such arguments. Co-authored-by: Terry Jan Reedy <tjreedy@udel.edu>

* GH-78079: Fix UNC device path root normalization in pathlib (GH-102003)Barney Gale2023-04-141-0/+24
| | | | | | | We no longer add a root to device paths such as `//./PhysicalDrive0`, `//?/BootPartition` and `//./c:` while normalizing. We also avoid adding a root to incomplete UNC share paths, like `//`, `//a` and `//a/`. Co-authored-by: Eryk Sun <eryksun@gmail.com>
* GH-101362: Omit path anchor from `pathlib.PurePath()._parts` (GH-102476)Barney Gale2023-04-091-2/+0

* GH-76846, GH-85281: Call `__new__()` and `__init__()` on pathlib subclasses ↵Barney Gale2023-04-031-1/+26
| | | | | | | | | (GH-102789) Fix an issue where `__new__()` and `__init__()` were not called on subclasses of `pathlib.PurePath` and `Path` in some circumstances. Paths are now normalized on-demand. This speeds up path construction, `p.joinpath(q)`, and `p / q`. Co-authored-by: Steve Dower <steve.dower@microsoft.com>

* GH-101362: Optimise PurePath(PurePath(...)) (GH-101667)Barney Gale2023-03-051-0/+27
| | | | | | | The previous `_parse_args()` method pulled the `_parts` out of any supplied `PurePath` objects; these were subsequently joined in `_from_parts()` using `os.path.join()`. This is actually a slower form of joining than calling `fspath()` on the path object, because it doesn't take advantage of the fact that the contents of `_parts` is normalized! This reduces the time taken to run `PurePath("foo", "bar")` by ~20%, and the time taken to run `PurePath(p, "cheese")`, where `p = PurePath("/foo", "bar", "baz")`, by ~40%.

* gh-100809: Fix handling of drive-relative paths in pathlib.Path.absolute() ↵Barney Gale2023-02-171-0/+20
| | | | | (GH-100812) Resolving the drive independently uses the OS API, which ensures it starts from the current directory on that drive.
* gh-101360: Fix anchor matching in pathlib.PureWindowsPath.match() (GH-101363)Barney Gale2023-02-171-3/+6
| | | | Use `fnmatch` to match path and pattern anchors, just as we do for other path parts. This allows patterns such as `'*:/Users/*'` to be matched.

* gh-68320, gh-88302 - Allow for private `pathlib.Path` subclassing (GH-31691)Barney Gale2022-12-231-30/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | Users may wish to define subclasses of `pathlib.Path` to add or modify existing methods. Before this change, attempting to instantiate a subclass raised an exception like: AttributeError: type object 'PPath' has no attribute '_flavour' Previously the `_flavour` attribute was assigned as follows: PurePath._flavour = xxx not set!! xxx PurePosixPath._flavour = _PosixFlavour() PureWindowsPath._flavour = _WindowsFlavour() This change replaces it with a `_pathmod` attribute, set as follows: PurePath._pathmod = os.path PurePosixPath._pathmod = posixpath PureWindowsPath._pathmod = ntpath Functionality from `_PosixFlavour` and `_WindowsFlavour` is moved into `PurePath` as underscored-prefixed classmethods. Flavours are removed.

* gh-78707: deprecate passing >1 argument to `PurePath.[is_]relative_to()` ↵Barney Gale2022-12-171-3/+5
| | | | | | | (GH-94469) This brings `relative_to()` and `is_relative_to()` more in line with other pathlib methods like `rename()` and `symlink_to()`. Resolves #78707.
* gh-99029: Fix handling of `PureWindowsPath('C:\<blah>').relative_to('C:')` ↵Barney Gale2022-11-251-9/+5
| | | | | | | (GH-99031) `relative_to()` now treats naked drive paths as relative. This brings its behaviour in line with other parts of pathlib, and with `ntpath.relpath()`, and so allows us to factor out the pathlib-specific implementation.

* gh-84538: add strict argument to pathlib.PurePath.relative_to (GH-19813)domragusa2022-10-281-0/+82
| | | | | | | | | | | | | | | | | | | | | | | By default, :meth:`pathlib.PurePath.relative_to` doesn't deal with paths that are not a direct prefix of the other, raising an exception in that instance. This change adds a *walk_up* parameter that can be set to allow for using ``..`` to calculate the relative path. example: ``` >>> p = PurePosixPath('/etc/passwd') >>> p.relative_to('/etc') PurePosixPath('passwd') >>> p.relative_to('/usr') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "pathlib.py", line 940, in relative_to raise ValueError(error_message.format(str(self), str(formatted))) ValueError: '/etc/passwd' does not start with '/usr' >>> p.relative_to('/usr', strict=False) PurePosixPath('../etc/passwd') ``` https://bugs.python.org/issue40358 Automerge-Triggered-By: GH:brettcannon

| | | | | | | | | | | | | | | | | | | | | | (GH-95450) Have pathlib use `os.path.join()` to join arguments to the `PurePath` initialiser, which fixes a minor bug when handling relative paths with drives. Previously: ```python >>> from pathlib import PureWindowsPath >>> a = 'C:/a/b' >>> b = 'C:x/y' >>> PureWindowsPath(a, b) PureWindowsPath('C:x/y') ``` Now: ```python >>> PureWindowsPath(a, b) PureWindowsPath('C:/a/b/x/y') ```
* gh-86943: implement `pathlib.WindowsPath.is_mount()` (GH-31458)Barney Gale2022-08-051-4/+5

* gh-93156 - fix negative indexing into absolute `pathlib.PurePath().parents` ↵Barney Gale2022-06-031-0/+5
| | | | | | | | | | | (GH-93273) When a `_PathParents` object has a drive or a root, the length of the object is *one less* than than the length of `self._parts`, which resulted in an off-by-one error when `path.parents[-n]` was fed through to `self._parts[:-n - 1]`. In particular, `path.parents[-1]` was a malformed path object with spooky properties. This is addressed by adding `len(self)` to negative indices.

* gh-92550 - Fix regression in `pathlib.Path.rglob()` (GH-92583)Barney Gale2022-05-101-17/+0
| | | | | | | We could try to remedy this by taking a slice, but we then run into an issue where the empty string will match altsep on POSIX. That rabbit hole could keep getting deeper. A proper fix for the original issue involves making pathlib's path normalisation more configurable - in this case we want to retain trailing slashes, but in other we might want to preserve `./` prefixes, or elide `../` segments when we're sure we won't encounter symlinks. This reverts commit ea2f5bcda1a392804487e6883be89fbad38a01a5.
