The behavior of WindowsPath is undefined when used with drive paths, specifically with no trailing slash:

WindowsPath('cc:').absolute() -> WindowsPath('C:/Users/maor/cc:')
WindowsPath('c:').absolute() -> WindowsPath('c:')
WindowsPath('c:').is_absolute() -> False
WindowsPath('c:') / 'p' -> WindowsPath('c:p')
WindowsPath('c:p').absolute() -> WindowsPath('c:p')
WindowsPath('c:p').is_absolute() -> False
msg338007 - (view) Author: Eryk Sun (eryksun) * Date: 2019-03-15 16:55
> WindowsPath('cc:').absolute() -> WindowsPath('C:/Users/maor/cc:')

This is correct. "cc:" is not a drive, i.e. the drive attribute is an empty string. pathlib handles this as an unqualified filename that gets resolved relative to the process current working directory.

Note that Windows allows a trailing colon for DOS devices such as "con:". Colons can also be used for file streams, but "cc:" isn't valid. The anonymous stream can only be specified explicitly by including the stream type, e.g. "cc::\$DATA".

> WindowsPath('c:').is_absolute() -> False
> WindowsPath('c:p').is_absolute() -> False
> WindowsPath('c:') / 'p' -> WindowsPath('c:p')

These are correct. Drive-relative paths depend on the current working directory of the drive. By definition they cannot be absolute. And the last one can be no more resolved than WindowsPath('spam/eggs') / 'p'.

Note that Windows gets the working directory for drives from 'hidden' environment variables such as "=C:". If no value is set for a drive, it defaults to the root directory. Windows uses these values, but never sets them itself. Applications and libraries such as the C runtime library are responsible for setting the values. CMD and Python both set them, but PowerShell does not.

> WindowsPath('c:').absolute() -> WindowsPath('c:')
> WindowsPath('c:p').absolute() -> WindowsPath('c:p')

This is a bug. absolute() should resolve "C:" to the current directory on the drive and join it with the remaining parts.

I agree.
So I'll open a PR that will:
1. Make the .absolute method return correct values in these cases
2. Add a regression test for this behavior
msg338663 - (view) Author: Maor Kleinberger (kmaork) * Date: 2019-03-23 10:31
Update after editing my PR - the bugs are:

1. WindowsPath('C:a').absolute() should return WindowsPath('C:\\d\\a') but returns WindowsPath('C:a').
This is caused by flawed logic in the parse_parts method of the _Flavour class.

2. WindowsPath('./b:a').absolute() should return WindowsPath('C:\\d\\b:a') but returns WindowsPath('b:a').
This is caused by the limited interface of parse_parts, and affects the Path.absolute, Path.expanduser and Path.__rtruediv__ methods.

3. WindowsPath('./b:a').resolve() should return WindowsPath('C:\\d\\b:a') but returns WindowsPath('b:a').
This is caused by missing logic in the resolve method and in Path.__str__

It'd be great if someone could review the PR so we can make progress with fixing the bugs.

[Note there is no absolute() method - I assume you mean resolve()]

Why? If './b:a' resulted from joining '.' and 'b:a', then it seems to
me that 'b:a' is "absolute-ish" (drive-relative) and so any preceding
path should be ignored (just like joining '.' and '/a/b/c' on POSIX).
The problem here is more to do with the fact that the simple POSIX
"absolute or relative" dichotomy isn't complete for Windows -
drive-relative paths like C:foo have some of the characteristics of
absolute paths and some of the characteristics of relative paths.

To put it another way, I'm comfortable with WindowsPath("./b:a")
returning "WindowsPath("b:a"). Of course, that's because I read b:a as
a drive plus a filename. If you read it as a filename with a stream,
then your interpretation is correct. But unless you check for all of
the valid drives currently available, it's not possible to make that
choice - both interpretations are equally valid. In fact, if you have
a file "C", and add a stream "file1" to it, is "C:file1" a file on the
C drive, or a stream in the file C? The problem is genuinely ambiguous
in that case, and cannot be solved without making an arbitrary choice.
Worse, WindowsPath("w:fred").resolve(strict=False) technically can't
even take account of whether drive w exists or file w exists or has a
stream fred. In that case, the question is fundamentally unanswerable.

I'd be reluctant to "solve" this issue with a fix that doesn't address
that problem - it would simply be replacing one weird behaviour with
another in an obscure corner case. (It may be that the "fix" is simply
to document the choices that the code currently makes).

> 3. WindowsPath('./b:a').resolve() should return WindowsPath('C:\\d\\b:a') but returns WindowsPath('b:a').
> This is caused by missing logic in the resolve method and in Path.__str__

Same as (2)

> It'd be great if someone could review the PR so we can make progress with fixing the bugs.

I don't think we should worry about the PR until it's clearly
established what the correct resolution actually is (or even whether
we consider all of these cases as bugs).

One bug was enough for me :)

> [Note there is no absolute() method - I assume you mean resolve()]
Of course there is an absolute() method, I'm not sure what you are saying...

> it seems to me that 'b:a' is "absolute-ish" (drive-relative)
I think that is incorrect. As written here: https://docs.microsoft.com/en-us/windows/desktop/fileio/naming-a-file#fully-qualified-vs-relative-paths, "If a file name begins with only a disk designator but not the backslash after the colon, it is interpreted as a relative path to the current directory on the drive with the specified letter."
In that case, WindowsPath('C:a').is_absolute() should return False, (as it does today) and WindowsPath('C:a').absolute() should return a path on drive C:, with 'a' joined with the working directory in drive C:.

> I'm comfortable with WindowsPath("./b:a") returning WindowsPath("b:a")
I disagree with that as well. "./b:a" is explicitly a path relative to the CWD (to a file named b:a). On the other hand, "b:a" should be (an is, in most windows programs) interpreted as a drive relative path.
For example, the ntpath module handles these cases correctly. When located in the directory C:\\d, this is the ntpath behavior:
ntpath.abspath('b:a') -> 'B:\\a'
ntpath.abspath('.\\b:a') -> 'C:\\d\\b:a'

In conclusion, I stand by my original fix offers. They are correct according to windows' documentation and behavior.

Huh, weird. It's not in
https://docs.python.org/3.7/library/pathlib.html But you're right, it
does exist...

OK, sure. My point is that "relative path to the current directory on
the drive with the specified letter" isn't a concept that matches how
"relative paths" are typically interpreted (most code interprets
"relative" as "relative to the CWD", and doesn't deal with the
possibility of per-drive CWDs).

> > I'm comfortable with WindowsPath("./b:a") returning WindowsPath("b:a")
> I disagree with that as well. "./b:a" is explicitly a path relative to the CWD (to a file named b:a). On the other hand, "b:a" should be (an is, in most windows programs) interpreted as a drive relative path.

Windows is inconsistent here - it can *also* be interpreted as a path
to a stream within a file. But it (virtually) never is.

> For example, the ntpath module handles these cases correctly. When located in the directory C:\\d, this is the ntpath behavior:
> ntpath.abspath('b:a') -> 'B:\\a'
> ntpath.abspath('.\\b:a') -> 'C:\\d\\b:a'

That second case only results in a valid filename if b:a is viewed as
a file-with-stream, but the first only makes sense if b:a is viewed as
a directory-relative file.

Also, in effect it means that Path(".") / some_path can return a
completely different location than some_path. Following documented
behaviour or not, that violates a pretty fundamental assumption that
users would expect to hold. And I think the problem is that
"drive-relative paths" are somewhat odd things that don't fit well in
the POSIX-derived model that Python's path APIs follow.

> In conclusion, I stand by my original fix offers. They are correct according to windows' documentation and behavior.

I remain of the view that the Windows documentation introduces a
concept ("relative path to the current directory on a specific drive")
that isn't well modelled by the current APIs, and the only "proper"
solution is to extend the API (like with the ideas of "drive" and
"reserved filenames", which are Windows-specific, but supported
everywhere). In the absence of that, I believe that any "fix" within
the existing model will have odd edge cases, and I don't think these
ones (specifically the "./b:a" cases) have *any* "obvious" answer.

I'm happy to agree to differ on this point, though. If the new
behaviour is just a side-effect of fixing absolute() to match the
cases Eryk commented on, then that's fine - I just wouldn't describe
the particular ./b:c cases as "bug fixes", rather as "changes in the
behaviour of cases no-one should actually care about" :-)

BTW, was there an actual use case for this issue, or was it simply a
theoretical concern? I'm actually much happier considering these cases
as "undefined" in practice (and just "not mentioned" in the docs),
rather than trying to pin it down precisely. I don't know of a case
where it actually benefits us to document this level of arguable
behaviour.

In pathlib, each path object has a drive, a root and path parts. Seeing pathlib's logic and tests (many tests are specifically testing the behavior of drive-relative paths), I think pathlib completely supports drive relative paths, with the exception of a few small bugs.

I think that when parsing windows paths, pathlib should behave exactly like the windows API does. This is crucial for interaction with the windows API itself or with other applications that might use it. I don't see any other way to parse windows paths other than according to the normal windows behavior.
Having said that, pathlib does a pretty good keeping the compatibility with the windows API, except for the small cases I found and brought forward in this issue report. From the information I gathered, when a path starts with one letter followed by a colon, windows treats it as a drive and continues parsing the rest of the path separately. That means that if you want to specify a path to a file in the CWD, with a single-character name and a file stream, you must precede the path with a "./" (See eryksun's comment on my PR before I fixed it https://github.com/python/cpython/pull/12361#discussion_r266193727).
Here is an example for the behavior of the windows API in this case:
win32api.GetFullPathName('b:a') -> 'B:\\a'
win32api.GetFullPathName('./b:a') -> 'C:\\Users\\maor\\b:a'

> Also, in effect it means that Path(".") / some_path can return a
completely different location than some_path.

This behavior is completely normal. Should WindowsPath('C:\\f') / WindowsPath('D:\\f2') return anything other than WindowsPath('D:/f2')?

> And I think the problem is that "drive-relative paths" are somewhat odd things that don't fit well in the POSIX-derived model that Python's path APIs follow.

As I wrote earlier, I think this is incorrect as the pathlib.Path class holds the attributes _drv, _root and _parts, which allows it to fully support drive-relative paths, by having a _drv and not having a _root.

> I'm happy to agree to differ on this point, though. If the new

I'm still that my case is convincing enough, but if not - does that require me to make any changes in order to make progress with my PR?

> BTW, was there an actual use case for this issue, or was it simply a

I've had an annoying bug using pathlib, traced it to the first bug I've presented in this issue, and discovered a few similar unhandled edge cases. Again, the "bugginess" I set upon to fix (call it a bug or  an undefined behavior) is an incompatibility issue with the way paths are normally treated in windows.

I'm not going to block this PR. I'd prefer it if we at least
documented the agreed behaviour, so that in future people don't come
along and say the new behaviour is wrong, but again I'm not going to
insist. I doubt I'll ever hit this edge case myself (either in code of
my own, or when working with others) so my only real interest is in
flagging up the concern. I'd like to hear what Eryk has to say on the
matter, though.

Ultimately the only person whose views matter are yours (as the person
writing the code) whoever commits the change.

Paul, I agree that joining Path(".") and Path("c:a") should yield Path("c:a"). However, I disagree that we should always be able to construct Path("a/b") from components Path("a") and Path("b"). It doesn't apply to Path("./c:a"). There's no way to split it up as the joining of two pathlib paths because there is no way to represent "c:a" by itself as anything other than a drive-relative path. The name "./c:a" has to be taken as a unit, which is fundamentally different from "c:a". pathlib agrees:

>>> p1 = Path('./c:a')
>>> p1
WindowsPath('c:a')
>>> [p1.drive, p1.root, p1.parts]
['', '', ('c:a',)]

>>> p2 = Path('.') / Path('c:a')
>>> p2
WindowsPath('c:a')
>>> [p2.drive, p2.root, p2.parts]
['c:', '', ('c:', 'a')]

Path('./c:a') is correctly parsed as a relative filename (no root and no drive). So, if it helps any, on the PR I wasn't requesting to change how it's parsed. The ambiguity is due to the way pathlib always collapses all "." components. I would like it to retain an initial "." component. That way the string representation will come out correctly as ".\\c:a" as opposed to the drive-relative path "c:a".

Some Windows API and runtime library functions behave differently depending whether a relative path has a leading "." or ".." component. We're at a disadvantage if we throw this information away. For example, "./spam/eggs.ext" and "spam/eggs.ext" can yield different results when searching for the file via SearchPathW, CreateProcessW (if using lpCommandLine, not lpApplicationName), or LoadLibraryExW (data/image DLL loading, not normal module loading). "./spam/eggs.ext" will be resolved relative to the process working directory, but "spam/eggs.ext" will be tried against every directory in the default file, executable, or library search path, which may not even include the working directory. (The latter behavior is unique to Windows. POSIX never searches for a name with a slash in it.)

The CreateProcessW case is a generalization of the case that we're used to across various platforms, in which, for the sake of security, the "." entry is excluded from PATH. In this case, the only way to run an executable in the working directory is to reference it explicitly. For example (in Linux):

>>> p = Path('./test.sh')
>>> open(p, 'w').write('#!/bin/sh\necho spam\n')
20
>>> os.chmod(p, 0o700)
>>> subprocess.call(['./test.sh'])
spam
0
>>> try: subprocess.call([str(p)])
... except FileNotFoundError: print('eggs')
...
eggs
>>> str(p)
'test.sh'

This would work if pathlib kept the initial "." component.

An example where we currently retain information that's not obviously needed is with ".." components. Even Path.absolute() retains ".." components. It's important in POSIX. For example, "spam/../eggs" shouldn't be reduced to "eggs" because "spam" might be a symlink. This doesn't generally matter in Windows, since it normalizes paths in user mode as strings before they're passed to the kernel, but we still don't throw the information away because it could be useful to code that implements POSIX-like behavior.

Ah, I think I follow now. But I'm not sure what you mean by wanting it
to "retain an initial '.' component" - how would you expect that to
work in practice? p1.parts == ('.', 'c:a')? I suspect that could break
existing code. In 99% of cases an initial ./ *is* semantically
irrelevant, and people expect it to be omitted. Upsetting that
expectation for something so rare, while technically correct, is
something we need to be careful of. Maybe it needs to be retained in a
new attribute in the Path object, which affects the str() conversion,
but not the existing attributes like parts.

> Some Windows API and runtime library functions behave differently depending whether a relative path has a leading "." or ".." component. We're at a disadvantage if we throw this information away.

Yes, I see your point now. Whether the initial string representation
was foo or ./foo is semantic information that we need to retain for
those places where it matters. But my concern is at the other end of
the equation - we need to be careful, having retained that semantic
information, not to have it intrude on existing, working use cases.

Thanks, this is a really useful example, as it makes it clear that
this is a general issue, not a platform-specific quirk.

Yes. Maybe not stripping an initial ./ can be modelled on that example
- the documentation
(https://docs.python.org/3.7/library/pathlib.html#pure-paths) says
"Spurious slashes and single dots are collapsed, but double dots
('..') are not, since this would change the meaning of a path in the
face of symbolic links" - that should be expanded to clarify that an
initial "." is similarly retained because removing it would change the
meaning in the face of  subprocess invocatioons which rely on it to
explicitly allow running a file from the current directory, or Windows
files with streams.

The exact behaviour needs to be clarified, of course:

Path('./a')
Path('./a:b')
Path('.', 'a')
Path('./', 'a')
Path('.', '.', 'a')

... etc. We should have well-defined behaviour for all of these (I'm
not saying it's *hard* to define the behaviour), and tests to ensure
it's followed.

Having said all of this, I'm not at all sure how much it relates to
the original description of this issue, which didn't mention initial
'./' components at all. Is the originally reported behaviour a
*consequence* of not retaining './', or is it a separate problem? If
the latter, then maybe "Pathlib should retain an initial './'" would
be better raised as a separate bpo item (and PR)?

I've dealt with that in my PR by checking in the __str__ method if the path could be misinterpreted, and if so prepending a './'.

In my opinion, this is a different problem, that its solution doesn't necessarily belong in pathlib. Pathlib is responsible to parse, manipulate and display paths correctly (which it fails to do with the case of Path('./a:b') -> Path('a:b')). In contrast, in the case of CreateProcessW, both Path('./exec') and Path('exec') are the *correct* paths to the executable. The ./ is not necessary in that case to display the path correctly, but just to interact correctly with CreateProcessW's interface.

I completely agree that any change made to support retaining the initial './' for process invocation should be made in a different bpo item and PR. I do disagree though, that such change should be made, as like I wrote above, this is only needed for CreateProcessW's interface, and isn't related to pathlib's logic itself.
Maybe, a nice idea would be to open a separate PR that would add a utility for dealing with executing paths. Something like Path.popen(cmd_args, **kwargs), that will call Popen with a path prepended with a './' if needed.

It's semantic information, just for different reasons than the "./c:a" case. In this case, it's about what a path means in a search context. I think specifying a filesystem path for a search disposition is as valid a use case as is specifying a path for an open or create disposition.

In Windows, the qualified path r".\exec" is resolved relative to just the working directory. Classically, for an unqualified name such as "exec", the working directory is checked after the application directory. Starting with Windows Vista, CreateProcessW and the CMD shell won't check the working directory at all for unqualified "exec" if NoDefaultCurrentDirectoryInExePath is set in the environment, not unless a "." entry is explicitly added to PATH.

The behavior of CreateProcessW also differs for r".\spam\exec" vs r"spam\exec". Without explicitly including the leading ".", the system searches every directory in the executable search path (i.e. the application directory, working directory, system directories, and PATH). This differs from Unix, in which any path with a slash in it is always resolved relative to the working directory. Getting this behavior in Windows requires using the qualified path r".\spam\exec".

We may want either behavior. I think if a path is specified explicitly with a leading "." component, or joined from one, the "." component should be preserved, just as we already preserve a leading ".." component.

This is a separate issue, as I suggested in the PR comment. It was just supposed to be a related issue that you might be interested in. I didn't intend to conflate it with this issue.
