2022-08-01Auto merge of #98246 - joshtriplett:times, r=m-ou-sebors-0/+31
Support setting file accessed/modified timestamps Add `struct FileTimes` to contain the relevant file timestamps, since most platforms require setting all of them at once. (This also allows for future platform-specific extensions such as setting creation time.) Add `File::set_file_time` to set the timestamps for a `File`. Implement the `sys` backends for UNIX, macOS (which needs to fall back to `futimes` before macOS 10.13 because it lacks `futimens`), Windows, and WASI.
2022-07-30Reset directory iteration in remove_dir_allChris Denton-1/+3
2022-07-15Return an error if trying to set a file timestamp to 0 on WindowsJosh Triplett-5/+12
This would otherwise silently ignore the attempt, since 0 serves as a flag to not set a timestamp.

2022-07-05Windows: Use `FindFirstFileW` if `metadata` failsChris Denton-10/+61
Usually opening a file handle with access set to metadata only will always succeed, even if the file is locked. However some special system files, such as `C:\hiberfil.sys`, are locked by the system in a way that denies even that. So as a fallback we try reading the cached metadata from the directory.

2022-06-25Rollup merge of #96412 - ChrisDenton:remove-dir-all, r=thomccMatthias Krüger-75/+81
Windows: Iterative `remove_dir_all` This will allow better strategies for use of memory and File handles. However, fully taking advantage of that is left to future work. Note to reviewer: It's probably best to view the `remove_dir_all_recursive` as a new function. The diff is not very helpful (imho).

It's possible that a file in the directory is pending deletion. In that case we might succeed after a few attempts.

2022-03-29Make the stdlib largely conform to strict provenance.Aria Beingessner-4/+7
Some things like the unwinders and system APIs are not fully conformant, this only covers a lot of low-hanging fruit.
2022-03-03Use `HandleOrNull` and `HandleOrInvalid` in the Windows FFI bindings.Dan Gohman-3/+4
Use the new `HandleOrNull` and `HandleOrInvalid` types that were introduced as part of [I/O safety] in a few functions in the Windows FFI bindings. This factors out an `unsafe` block and two `unsafe` function calls in the Windows implementation code. And, it helps test `HandleOrNull` and `HandleOrInvalid`, which indeed turned up a bug: `OwnedHandle` also needs to be `#[repr(transparent)]`, as it's used inside of `HandleOrNull` and `HandleOrInvalid` which are also `#[repr(transparent)]`.

2022-02-08Rollup merge of #93206 - ChrisDenton:ntopenfile, r=nagisaMatthias Krüger-3/+8
Use `NtCreateFile` instead of `NtOpenFile` to open a file Generally the internal `Nt*` functions should be avoided but when we do need to use one we should stick to the most commonly used for the job. To that end, this PR replaces `NtOpenFile` with `NtCreateFile`. NOTE: The initial version of this comment hypothesised that this may help with some recent false positives from malware scanners. This hypothesis proved wrong. Sorry for the distraction.

2022-01-25Rollup merge of #88794 - sunfishcode:sunfishcode/try-clone, r=joshtriplettMatthias Krüger-1/+1
Add a `try_clone()` function to `OwnedFd`. As suggested in #88564. This adds a `try_clone()` to `OwnedFd` by refactoring the code out of the existing `File`/`Socket` code. r? ``@joshtriplett``

2021-10-30Auto merge of #89174 - ChrisDenton:automatic-verbatim-paths, r=dtolnaybors-13/+14
Automatically convert paths to verbatim for filesystem operations that support it This allows using longer paths without the user needing to `canonicalize` or manually prefix paths. If the path is already verbatim then this has no effect. Fixes: #32689
