异常持续高 CPU 占用 #1100

ClarkQAQ · 2024-07-26T09:08:41Z

Summary

问题简述

在运行 fcitx5 后 10 分钟左右会占满一个核心的 CPU, 并且会一直持续没有要停下来的意思

尝试分析

在 Arch Linux CN 群组依云的提议和帮助下抓取了 perf 并生成了火焰图

这是 perf 原始数据和 stackcollapse-perf 的中间输出

fcitx-perf.tar.gz

以及通过 strace 抓取的大量 epoll_pwait2

strace.txt

Steps to Reproduce

运行 fcitx5 然后等待 10 分钟左右, 中间使用电报聊聊天或者就这样放着

Expected Behavior

正常运行

Frontends setup:

The environment variable checked by this script only shows the environment under current shell. It is still possible that you did not set the environment to the whole graphic desktop session. You may inspect the actual environment variable of a certain process by using xargs -0 -L1 /proc/$PID/environ for a certain process that you find not working.

Xim:

${XMODIFIERS}:

Environment variable XMODIFIERS is set to "@im=fcitx" correctly.
Xim Server Name from Environment variable is fcitx.
XIM_SERVERS on root window:

Xim server name is the same with that set in the environment variable.
XIM encoding:

Your LC_CTYPE is set to C whose encoding is not UTF-8. You may have trouble committing strings using XIM.

Following error may not be accurate because guessing Qt version from path depends on how your distribution packages Qt. It is not a critical error if you do not use any Qt application with certain version of Qt or you are using text-input support by Qt under Wayland.
Cannot find fcitx5 input method module for Qt4.

Gtk:

gtk - ${GTK_IM_MODULE}:

Please set environment variable GTK_IM_MODULE to "fcitx" using the tool your distribution provides or add export GTK_IM_MODULE=fcitx to your ~/.xprofile. See Input Method Related Environment Variables: GTK_IM_MODULE.

It is OK to use gtk built-in Wayland im module if your compositor fully supports text-input protocol used by gtk.

应该是因为这个 bug curl/curl#14280 可以不用云拼音，或者降级 curl

adam900710 · 2024-08-02T01:48:12Z

同样遇到这个bug,确认关闭云拼音之后没有再出现过100% CPU占用

@adam900710 升级curl 8.9.1 应该也可以修复
