2025-02-03io/fs: add ReadLinkFS interfaceRoxy Light
Added implementations for *io/fs.subFS, os.DirFS, and testing/fstest.MapFS. Amended testing/fstest.TestFS to check behavior. Addressed TODOs in archive/tar and os.CopyFS around symbolic links. I am deliberately not changing archive/zip in this CL, since it currently does not resolve symlinks as part of its filesystem implementation. I am unsure of the compatibility restrictions on doing so, so figured it would be better to address independently. testing/fstest.MapFS now includes resolution of symlinks, with MapFile.Data storing the symlink data. The behavior change there seemed less intrusive, especially given its intended usage in tests, and it is especially helpful in testing the io/fs function implementations.

2024-05-23all: change from sort functions to slices functions where feasibleIan Lance Taylor
Doing this because the slices functions are slightly faster and slightly easier to use. It also removes one dependency layer. This CL does not change packages that are used during bootstrap, as the bootstrap compiler does not have the required slices functions. It does not change the go/scanner package because the ErrorList Len, Swap, and Less methods are part of the Go 1 API.

2023-10-11testing/fstest: MapFS: set perm 0555 on synthetized dirsOlivier Mengué
As MapFS ignores filemodes and always grant read and traverse access on directories, let's make synthetized directory entries to expose filemode 0555 instead of 0000. Fixes #63468.

2021-12-13all: gofmt -w -r 'interface{} -> any' srcRuss Cox
And then revert the bootstrap cmd directories and certain testdata. And adjust tests as needed. Not reverting the changes in std that are bootstrapped, because some of those changes would appear in API docs, and we want to use any consistently. Instead, rewrite 'any' to 'interface{}' in cmd/dist for those directories when preparing the bootstrap copy. A few files changed as a result of running gofmt -w not because of interface{} -> any but because they hadn't been updated for the new //go:build lines. Fixes #49884.

2020-12-04io/fs: add SubRuss Cox
Sub provides a convenient way to refer to a subdirectory automatically in future operations, like Unix's chdir(2). The CL also includes updates to fstest to check Sub implementations. As part of updating fstest, I changed the meaning of TestFS's expected list to introduce a special case: if you list no expected files, that means the FS must be empty. In general it's OK not to list all the expected files, but if you list none, that's almost certainly a mistake - if your FS were broken and empty, you wouldn't find out. Making no expected files mean "must be empty" makes the mistake less likely - if your file system ever worked, then your test will keep it working. That change found a testing bug: embedtest was making exactly that mistake. Fixes #42322.
