tempfile VS OpenDoas

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.

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.

Aditionally,because doas was developed for OpenBSD,it also retains some of its quirks,like how user-installed executables are stored in /usr/local/bin,in contrast to /usr/bin where Linux stores them. As a result,doas can have problems on Linux so the following workaround can be used:

That's a pretty severe unsolved security issue.

If you want to move away from Sudo, but don't want to try this rust implementation just yet, I have had great success with OpenBSD's doas. It has been ported to every Linux distro I know of as well:

There are, at both ends. Both the "script kiddies" who cannot deviate from scripts because they lack almost any knowledge at all; and the knowledgeable ones who know that there are subtle differences between sudo and doas which require doing things slightly differently to achieve the same effect.

Doas makes more in openbsd world In linux there are many api that need to be changed for porting, i'm no expert but the port might be flawed as not many developers has checked the codebase And how can you explain this vulnerability https://github.com/Duncaen/OpenDoas/issues/106

Personally I'd prefer running Qubes OS, if only my device would have been more powerful. Currently I'm on Fedora Silverblue as I believe it provides a decent middle-ground in which I'm more secure than almost any other Linux distro while not losing any (meaningful) functionality. I do make use of doas and other technologies inspired from OpenBSD to further enhance the security.

Why not port https://github.com/Duncaen/OpenDoas to rust instead?

If the goal is security, then there is more to it than just using a memory safe language. Otherwise the result of this, possibly unwittingly, seems performative.
