[Bug] Flymake counter keeps increasing when using auctex-cont-latexmk

[hannesmeinlschmidt]

Thank you for the bug report

• I am using the latest version of doom-modeline related packages.
• I checked FAQ.
• You may also try reproduce the issue using clean environment and minimal configurations with
  the command emacs -Q.

Bug description

In my LaTeX workflow, I am using auctex-cont-latexmk to run latexmk continuously in the background whenever change to the buffer are detected. The package also offers a flymake backend that reports back the warnings and errors from the compilation log.

I understand that auctex-cont-latexmk runs on a timer to report the issues to flymake. This works just fine with the regular modeline, but in doom-modeline, the flymake issues counter keeps increasing every few seconds. The flymake diagnostics buffer displays the correct issues, it's just the displayed number of issues in doom-modeline that keeps increasing. The number stops increasing once one makes a change to the buffer. My understanding from the auctex-cont-latexmk source is that this tells its flymake report backend that the report may be outdated, so it stops reporting.

I am not confident that this is an issue with doom-modeline itself and the way it collects the issues from flymake, or rather with an incorrect way of flymake reporting from auctex-cont-latexmk, but since with the original modeline, the problem does not occur, I have opened the issue here to clarify.

The issue is reproducable also with emacs -Q, loading only auctex-cont-latexmk and doom-modeline and activating flymake.

Steps to reproduce

Activate auctex-cont-latexmk with auctex-cont-latexmk-toggle in a tex buffer where compilation will raise an error or warning. doom-modeline will show an increasing number of issues, the original modeline will not.

Here is a minimal example where the warning arising from the wrong reference will trigger the issue:

\documentclass{article}
%
\begin{document}
This is a test.
\begin{equation}
  \label{eq:debug}
  e^{i \pi} = -1
  \end{equation}
This is a wrong reference:~\ref{eq:debugg}.
\end{document}

Expected behavior

The number of flymake issues reported in doom-modeline should not increase whenever the flymake backend of auctex-cont-latexmk issues an unchanged report.
