tempfile VS sudo

I need to do some tests with files operations, what's the best practice in regards to creating temporary files in tests ? I heard about tempfile but is there a more idiomatic way to do that ?

The sudo-rs Cargo.toml [1] file seems very reasonable. This is the curse of being cross platform. The inclusion of https://github.com/Stebalien/tempfile as a dependency is responsible for the overwhelming majority of lines due to including *-sys crates for multiple OSs.

~/Code/tempfile !! tokei vendor

Eventually, I had to test reading of input file and generation of the html file. To do this, I would need to create test files for input and output for this scenario. However, this could cause problems unless I named all the test files differently as tests usually run in parallel. So, I decided to use the tempfile crate to create a temporary test directory for each test (where needed):

Create a NamedTempFile with the tempfile crate.

Even better would be to create a tempdir and populate it during the test run. Try the tempfile crate.

Not the same commenter but you could use a tempfile

That said though; there are a few solutions for the problem you're describing. One would be to have a "temp file" type which knows how to delete itself when dropped, but can manually be converted into a permanent file in the case of success. Crates like tempfile provide abstractions for this.

tempdir was merged into tempfile.

It depends on whether sudo was compiled with --disable-env-reset or not, it's on by default[1].

Also some variables are inherited regardless (e.g. DISPLAY, TERM), and some useful ones (e.g. HOME) are initialized by sudo, but I can't tell where that's done.

Side note that I've always found interesting: sudo is almost entirely maintained by one dude: https://github.com/sudo-project/sudo/graphs/contributors

The n=2 case also occurs in the commit: https://github.com/sudo-project/sudo/commit/7873f8334c8d3103...

And indeed, the two values ate bitwise complements.

One feature they didn't mention they left out was the ability to run `make me a sandwich` (https://github.com/sudo-project/sudo/blob/main/Makefile.in#L...)

It's (kind of) back - https://github.com/sudo-project/sudo/commit/9757d29a24ac1872872cf09757b0439c54089707

Fun fact, the “incident will be reported” message was close to being removed from sudo recently: https://github.com/sudo-project/sudo/commit/6aa320c96a37613663e8de4c275bd6c490466b01
