Revert saved code frequently.

[zw963]

This issue happen a lot recent days when i am working a lucky project.

I use emacs, crystalline features work quite well with my emacs lsp-mode, even , i can jump into source code sometimes.

But one issue happen frequently, make me almost want to give up.

this issue happen quite randomally, after i saved code, code revert immedately unexpected.

i even don't mind those revert ( it happen very quick), often i found this issue happen only because the
crystal build status never changed after fix bug.

Anyway, i will try to capture some LSP IO debug output next time happen.

please give me some clue about why this happen, only for me??

this probably related to #41 too.

thanks

It happen again, i saw some logs like following:

Come from crystalline stderr:

[warn] evutil_make_internal_pipe_: pipe: Too many open files
[err] evsig_init_: socketpair: Too many open files

Process crystalline stderr finished

Come from lsp-log:

Forget to mention, every time meet this issue, i run lsp to initalize lsp again will solve this issue.

This issue is gone after delete following line in my lsp config.

(add-hook 'before-save-hook #'lsp-format-buffer t t)

I need more time to test if this issue caused by lsp-format-buffer conflict with other formatting mode.

[zw963]

After test a while, quite ensure, this issue related to above lsp-foramt-buffer before save hook, if disable it, no this issue.

But the formatter advice of lsp-format-buffer come from crystalline, right?

I use lsp-mode for a long time, others mode (e.g. dart-mode, rust-mode, go-mode) no this format issue anyway.

[zw963]

I record a video, for describe how this bug happen when i edit a file called 1.cr.

Screencast_06_03_2024_07.13.35_PM.mp4

Explain on the above video:

1. after some changes, i try to save 1.cr
2. then, a part of my file get rollbacked.
3. i try again, use editor undo feature to revert my buffer to the status before save.
4. i try to save buffer again, part of my file get revert again.
