Add more details to FileManager error report #1895

MrStevns · 2024-11-24T10:53:01Z

The purpose of this PR has been to make the error report cover more steps, introduce "Error" to make it more explicit what's a information, a warning and an error.

I've also tried to make it fail faster rather than spitting out all kinds of irrelevant information when the actual error happened 4 lines above.

Here's an example of what our current report looks like:

Raw file path: /Users/mrstevns/Desktop/p2d testing/test-save-corruption.pclx
Resolved file path: /Users/mrstevns/Desktop/p2d testing/test-save-corruption.pclx
  File name: /Users/mrstevns/Desktop/p2d testing/test-save-corruption.pclx
  Recognized New zipped Pencil2D File Format (*.pclx) !

end

And here's the new one:

    Found an error while reading the file. Error code: 7, reason: failed finding central directory
    Found an error while closing the file. Error code: 24, reason: invalid parameter
  
Error: Unable to extract project, miniz sanity check failed.

[System Info]

  Pencil2D version: 0.0.0.0 (dev)
  Build ABI: x86_64-little_endian-lp64
  Kernel: darwin, 21.6.0
  Operating System: macOS 12.7
  Language: en_GB

In addition the error dialog now also has a "Copy to clipboard" button, so the user can more easily paste the error report.

The problem with not aborting here is that while one file can fail, it will be noted down but if the next file succeeds, then it will seem like the project got compressed successfully.

And get rid of useless or confusing information.

The logic didn't account for existing files with "backup" suffix, eg. A folder may contain: MyProject.pclx MyProject.backup1.pclx If the user opened MyProject.pclx, and failed to save it later, the logic would not count existing backup files like: "MyProject.backup1.pclx" and as such the result would be no backup being made.

…non existent files This is caused by the new logic actually catching when a file has gone missing while saving. While it may not fix any bugs inheritly, it should make it easier to diagnose problems in the future.

I'm blown away by the fact that this worked at all... wtf. The only one who reported a problem here was windows but technically the file should never have been closed on any of them. Frightening..

And move some closer to the open call to make sure it happens when the scope ends.

    }

    mz_zip_archive* mz = new mz_zip_archive;
+    ScopeGuard mzScopeGuard([&] {


OnScopeExit(delete mz);

I knew about OnScopeExit when I made this change, I just prefer using ScopeGuard directly rather than a macro

Thanks for thoroughly revising all the project load/save error logs and adding the missing parts. This is very important. Apart from the explicit QFile::close calls, everything looks great to me!
