2023-11-07[release-branch.go1.20] path/filepath: fix various issues in parsing Windows ↵Damien Neil
paths On Windows, A root local device path is a path which begins with \\?\ or \??\. A root local device path accesses the DosDevices object directory, and permits access to any file or device on the system. For example \??\C:\foo is equivalent to common C:\foo. The Clean, IsAbs, IsLocal, and VolumeName functions did not recognize root local device paths beginning with \??\. Clean could convert a rooted path such as \a\..\??\b into the root local device path \??\b. It will now convert this path into .\??\b. IsAbs now correctly reports paths beginning with \??\ as absolute. IsLocal now correctly reports paths beginning with \??\ as non-local. VolumeName now reports the \??\ prefix as a volume name. Join(`\`, `??`, `b`) could convert a seemingly innocent sequence of path elements into the root local device path \??\b. It will now convert this to \.\??\b. In addition, the IsLocal function did not correctly detect reserved names in some cases: - reserved names followed by spaces, such as "COM1 ". - "COM" or "LPT" followed by a superscript 1, 2, or 3. IsLocal now correctly reports these names as non-local.

2023-02-14[release-branch.go1.20] path/filepath: do not Clean("a/../c:/b") into c:\b ↵Damien Neil
on Windows Do not permit Clean to convert a relative path into one starting with a drive reference. This change causes Clean to insert a . path element at the start of a path when the original path does not start with a volume name, and the first path element would contain a colon. This may introduce a spurious but harmless . path element under some circumstances. For example, Clean("a/../b:/../c") becomes `.\c`. This reverts CL 401595, since the change here supersedes the one in that CL. Thanks to RyotaK (https://twitter.com/ryotkak) for reporting this issue.

2022-11-09path/filepath: detect all forms of \\ volume paths on WindowsDamien Neil
Previously, the volumeNameLen function checked for UNC paths starting with two slashes, a non-'.' character, and another slash. This misses volume names such as "\\.\C:\". The previous check for volume names rejects paths beginning with "\\.". This is incorrect, because while these names are not UNC paths, "\\.\C:\" is a DOS device path prefix indicating the C: device. It also misses UNC path prefixes in the form "\\.\UNC\server\share\". The previous check for UNC paths also rejects any path with an empty or missing host or share component. This leads to a number of possibly-incorrect behaviors, such as Clean(`\\a`) returning `\a`. Converting the semantically-significant `\\` prefix to a single `\` seems wrong. Consistently treat paths beginning with two separators as having a volume prefix. Update VolumeName to detect DOS device paths (`\\.\` or `\\?\`), DOS device paths linking to UNC paths (`\\.\UNC\Server\Share` or `\\?\UNC\Server\Share`), and UNC paths (`\\Server\Share\`). Clean(`\\a`) = `\\a` Join(`\\`, `a`, `b`) = `\\a\b` In addition, normalize path separators in VolumeName for consistency with other functions which Clean their result.

2020-11-06io/fs: add WalkDirRuss Cox
This commit is a copy of filepath.WalkDir adapted to use fs.FS instead of the native OS file system. It is the last implementation piece of the io/fs proposal. The original io/fs proposal was to adopt filepath.Walk, but we have since introduced the more efficient filepath.WalkDir (#42027), so this CL adopts that more efficient option instead. (The changes in path/filepath bring the two copies more in line with each other. The main change is unembedding the field in statDirEntry, so that the fs.DirEntry passed to the WalkDirFunc for the root of the tree does not have any extra methods.) For #41190.

2015-06-29path/filepath: document and test behavior of SkipDir on filesRuss Cox
This behavior is not what we might have designed from the start, but it has been present since Go 1. Rather than make a visible behavioral change that might cause programs to work differently in Go ≤1.4 vs Go ≥1.5, document what SkipDir on a non-directory has always meant. If code doesn't want this meaning, it is easy enough not to return SkipDir on non-directories. Fixes #10533.

2015-01-20path/filepath: make Join handle UNC paths on WindowsEmil Hessman
Unless the first element is a Universal Naming Convention (UNC)[0] path, Join shouldn't create a UNC path on Windows. For example, Join inadvertently creates a UNC path on Windows when told to join at least three non-empty path elements, where the first element is `\` or `/`. This CL prevents creation of a UNC path prefix when the first path element isn't a UNC path. Since this introduces some amount of Windows-specific logic, Join is moved to a per GOOS implementation. Fixes #9167.
