2024-04-26path/filepath, internal/filepathlite: move parts of filepath to filepathliteDamien Neil
The path/filepath package needs to depend on the os package to implement Abs, Walk, and other functions. Move the implementation of purely lexical functions from path/filepath into internal/filepathlite, so they can be used by os and other low-level packages.

2023-01-20path/filepath: fix evaluation of symlinks to paths under /tmp on macOSmatsuyoshi30
For symlinks created from symlinks under the root directory created as the relative path (e.g., symbolic links under /tmp), we update vol and volLen.

2020-10-20all: update references to symbols moved from os to io/fsRuss Cox
The old os references are still valid, but update our code to reflect best practices and get used to the new locations. Code compiled with the bootstrap toolchain (cmd/asm, cmd/dist, cmd/compile, debug/elf) must remain Go 1.4-compatible and is excluded. For #41190.

2019-03-05path/filepath: don't discard .. in EvalSymlinksIan Lance Taylor
EvalSymlinks was mishandling cases like "/x/../../y" or "../../../x" where there is an extra ".." that goes past the start of the path.

2019-03-01path/filepath: do not call GetFinalPathNameByHandle from EvalSymlinksAlex Brainman
EvalSymlinks is using GetFinalPathNameByHandle to handle symlinks with unusual targets like \??\Volume{ABCD}\. But since CL 164201, os.Readlink handles path like that too. So remove all that extra code that EvalSymlinks calls when os.Readlink fails - it is not needed any more. Now that windows EvalSymlinks implementation is similar to unix implementation, we can remove all slashAfterFilePathError related code too. So do that. This also makes TestIssue29372 pass even when TMP directory refers to symlinks with target like \??\Volume{ABCD}\. So remove TestIssue29372 code that helped it pass on windows-arm. TestIssue29372 should pass as is now.

CL 155597 attempted to fix #29372. But it failed to make all new test cases pass. Also CL 155597 broke some existing code (see #29449 for details).

For a relative symlink in the root directory, such as /tmp -> private/tmp, we were dropping the leading slash. No test because we can't create a symlink in the root directory.
