checksum: prepare further behavior fix with a rework #6822

RenjiSann · 2024-10-25T03:10:15Z

Now that #6782, #6793 and #6815 have landed, it is time to achieve the rework of checksum.rs started in #6654.

This will allow us to fix #6572, #6614 and #6653.

This PR mainly tries to split the massive perform_checksum_verification in smaller functions, and to get rid of the &mut ChecksumResult that is passed everywhere, which makes it very difficult to understand where the global state of the program is modified.

Also, it adds ignored tests for future features (it will prevent too many conflicts when rebasing future PRs on each other).

Next PRs will focus on reworking the algorithm detection behavior, in particular for blake2b size guessing,
Regex detection behavior which for now prevents us from encountering both hexa and base64 digits in the same file.

Depending on the feedback on this discussion, I might split the checksum.rs file into several files (a bit like the initial PR #6654).
I'd like to move Error structs to checksum/error.rs, everything that's Algorithm-related to checksum/algo.rs, etc...

What do you think ?

It sounds good to me.

I've finally decided to keep the splitting in several files for later, because it's a nightmare to mix changes and file architecture when you have to rebase to keep a sound change history.

I'm not sure why the macos test failed. Is it just flakey or have I touched something ?

@cakebaker Both of your comments address the details of implementation I came to when working on it.
If you come up with better alternatives, I'll gladly hear them ^^

Overall good job with this refactoring :)

Up @cakebaker
Once this is done, I will move on and fix the tests I added :)

RenjiSann · 2024-11-16T21:33:13Z

This PR might have been forgotten, just pinging maintainers for final review/merge @cakebaker @sylvestre ^^
