[SOLVED] Multiple executions: SIGRTMIN, dwmblocks, and statuscmd

[Member techore]

Posting the problem and solution should someone else run into this particular issue.

Scenario:
antiX kernel 4.9.0 and dwmblocks with statuscmd patch to support mouse click interaction using SIGRTMIN to execute commands or scripts.

Symptom:
For each trigger, mouse click, statuscmd executes targeted command or script between 1 and 15 times. Varies on each click. Observed the symptoms using kernels 4.9.0-326 and 4.9.0-264.

Testing:
1. Asustek G750JX manufactured 2013
2. Asustek N705U manufactured 2018

Steps taken to trouble shoot:
1. Disable all dwm patches except dwmblocks, statuscmd, and tiling and monocle layouts. Issue persisted.
2. Swapped mice because I know someone was going to ask. 🙂 if it is a mouse issue. Issue persisted.
3. Used xev to identify if multiple clicks per click. Mouse clicks operated as expected via xev.
4. Install on a different computer. Issue persisted.

Root cause: unknown but my hypothesis is buggy kernel support for SIGRTMIN.

Solution:
Upgrade to an antiX 5.10 kernel. Kernel tested was 5.10.142.

Hopefully, no one else runs into this issue, but if they do, I hope this post helps.
