Version: Waybar v0.9.22-215-g7dfc7200 (branch 'master')
Installed with the AUR package waybar-git
Distro: EndeavourOS
Kernel: 6.5.9-arch2-1
WM/DE: Hyprland

Basically if I run waybar normally, it will eat ~16% of my CPU, but if I run it with the "-l debug" option, it runs normal and doesn't eat CPU at all. Tested on Hyprland, commit 062f749

Edit:

this bug is strange, basically when I terminated the waybar process and then run waybar -l debug, it used to run waybar normal but it happens that will eat the same amount of CPU as when running normally, continuing to spam [2023-11-02 15:07:42.326] [debug] waitpid failed: No child processes

I believe I'm affected by the same issue which is caused by last commit squeezed in before release: #2629.

It adds reaping of child command process to the main reap queue:

Waybar/include/util/command.hpp

Lines 115 to 117 in c6a9b63

reap_mtx.lock();
reap.push_back(child_pid);
reap_mtx.unlock();

ignoring the fact that it's already being reaped through close:

Waybar/src/modules/custom.cpp

Line 71 in c6a9b63

exit_code = WEXITSTATUS(util::command::close(fp_, pid_));

Waybar/include/util/command.hpp

Lines 44 to 67 in c6a9b63

inline int close(FILE* fp, pid_t pid) {
int stat = -1;
pid_t ret;
fclose(fp);
do {
ret = waitpid(pid, &stat, WCONTINUED | WUNTRACED);
if (WIFEXITED(stat)) {
spdlog::debug("Cmd exited with code {}", WEXITSTATUS(stat));
} else if (WIFSIGNALED(stat)) {
spdlog::debug("Cmd killed by {}", WTERMSIG(stat));
} else if (WIFSTOPPED(stat)) {
spdlog::debug("Cmd stopped by {}", WSTOPSIG(stat));
} else if (WIFCONTINUED(stat)) {
spdlog::debug("Cmd continued");
} else if (ret == -1) {
spdlog::debug("waitpid failed: {}", strerror(errno));
} else {
break;
}
} while (!WIFEXITED(stat) && !WIFSIGNALED(stat));
return stat;
}

Both of these now race as to who will be the first to successfully waitpid for the child. One will handle process exit successfully, while the other will fail with ECHILD. Unfortunately none of them handles ECHILD correctly:

  • SIGCHLD handler will accumulate such pids indefinitely in reap:

    Waybar/src/main.cpp

    Lines 29 to 41 in c6a9b63

    case SIGCHLD:
    spdlog::debug("Received SIGCHLD in signalThread");
    if (!reap.empty()) {
    reap_mtx.lock();
    for (auto it = reap.begin(); it != reap.end(); ++it) {
    if (waitpid(*it, nullptr, WNOHANG) == *it) {
    spdlog::debug("Reaped child with PID: {}", *it);
    it = reap.erase(it);
    }
    }
    reap_mtx.unlock();
    }
    break;
  • close will start infinite loop

    Waybar/include/util/command.hpp

    Lines 49 to 65 in c6a9b63

    do {
    ret = waitpid(pid, &stat, WCONTINUED | WUNTRACED);
    if (WIFEXITED(stat)) {
    spdlog::debug("Cmd exited with code {}", WEXITSTATUS(stat));
    } else if (WIFSIGNALED(stat)) {
    spdlog::debug("Cmd killed by {}", WTERMSIG(stat));
    } else if (WIFSTOPPED(stat)) {
    spdlog::debug("Cmd stopped by {}", WSTOPSIG(stat));
    } else if (WIFCONTINUED(stat)) {
    spdlog::debug("Cmd continued");
    } else if (ret == -1) {
    spdlog::debug("waitpid failed: {}", strerror(errno));
    } else {
    break;
    }
    } while (!WIFEXITED(stat) && !WIFSIGNALED(stat));

I would revert 1c1a39f possibly followed by improving waitpid error handling.

100% of a core gets eaten up by waybar on my machine too.
Modules:

    "battery",
    "disk#root",
    "disk#storage",
    "disk#server",
    "memory",
    "temperature#cpu",
    "temperature#gpu",
    "temperature#gpu-hotspot",
    "temperature#gpu-mem",

    "wireplumber",

EDIT: as per other comments, disabling all the custom ones works around the problem

Same problem for me since upgrading to Waybar v0.9.23 (installed via the Arch Linux respositories), 100% load on one CPU core. Log Level Debug does not seem to make any difference for me.
Distro: Arch Linux
Kernel: 6.5.9-arch2-1
WM: Sway

After some trial and error I found out that the CPU load is normal without a custom module, which I am using:

"custom/weather": {
    "format": "{}",
    "tooltip": false,
    "exec": "curl -s 'https://wttr.in/Berlin?format=%l:%20%t%20%c'",
    "interval": 3600
}

Not sure if the configuration is correct, I can only say that the module works fine after a downgrade to Waybar v0.9.22.

Same here, any custom module that uses terminal commands makes one of CPU cores always run at 100%. Downgrading to 0.9.22 fixes it, too bad persistent workspaces are broken in 0.9.22...
Oddly, adding a 1 second delay to my custom weather widget, makes it work normally. But that didn't help when i tried it on my pacman and aur widgets. Nevermind, it's back to 100% after about 10 minutes.

Not a "+1" fan, but waybar uses up to 300% cpu (htop) here since updating to v0.9.23 running Arch Linux.
I'm using a lot of custom modules and have to disable all of them or downgrade waybar to v0.9.22 in order to get back to a normal cpu usage.

The same problem. It eats up to 300% of my CPU cores. But when I remove my custom modules, it works normally.

Can someone with the problem can test by reverting this commit bf371f7

@Alexays issue remains after reverting bf371f7 but that was kind of expected. The actual issue was already bisected and explained (#2631 (comment)) or you don't agree with this analysis?

I had to downgrade. Noticed on my laptop this morning (potato)

Yep I can totally confirm this too. on 0.9.22 Waybar seems to use a decently normal amount of cpu
image

On waybar 0.9.23, however, it starts at ~20% cpu usage and keeps rising.
On my config, this seems to be caused by my media player modules, but the default config also has this issue, starting at around 10%.
image

I can also confirm that starting with --log-level [anything] makes the cpu usage more normal (starting at around 5% and rising)

Also, on 0.9.23 the media player modules I previously mentioned appear weird, where some of them appear and others don't on some monitors.

Weirdly enoguh, can't repro it on the master branch (yet).

I believe I'm affected by the same issue which is caused by last commit squeezed in before release: #2629.

It adds reaping of child command process to the main reap queue:

Waybar/include/util/command.hpp

Lines 115 to 117 in c6a9b63

reap_mtx.lock();
reap.push_back(child_pid);
reap_mtx.unlock();

ignoring the fact that it's already being reaped through close:

Waybar/src/modules/custom.cpp

Line 71 in c6a9b63

exit_code = WEXITSTATUS(util::command::close(fp_, pid_));

Waybar/include/util/command.hpp

Lines 44 to 67 in c6a9b63

inline int close(FILE* fp, pid_t pid) {
int stat = -1;
pid_t ret;
fclose(fp);
do {
ret = waitpid(pid, &stat, WCONTINUED | WUNTRACED);
if (WIFEXITED(stat)) {
spdlog::debug("Cmd exited with code {}", WEXITSTATUS(stat));
} else if (WIFSIGNALED(stat)) {
spdlog::debug("Cmd killed by {}", WTERMSIG(stat));
} else if (WIFSTOPPED(stat)) {
spdlog::debug("Cmd stopped by {}", WSTOPSIG(stat));
} else if (WIFCONTINUED(stat)) {
spdlog::debug("Cmd continued");
} else if (ret == -1) {
spdlog::debug("waitpid failed: {}", strerror(errno));
} else {
break;
}
} while (!WIFEXITED(stat) && !WIFSIGNALED(stat));
return stat;
}

Both of these now race as to who will be the first to successfully waitpid for the child. One will handle process exit successfully, while the other will fail with ECHILD. Unfortunately none of them handles ECHILD correctly:

* `SIGCHLD` handler will accumulate such pids indefinitely in `reap`:
  https://github.com/Alexays/Waybar/blob/c6a9b63189c1617606ba726f3fd7af5a80df97d6/src/main.cpp#L29-L41

* `close` will start infinite loop
  https://github.com/Alexays/Waybar/blob/c6a9b63189c1617606ba726f3fd7af5a80df97d6/include/util/command.hpp#L49-L65

I would revert 1c1a39f possibly followed by improving waitpid error handling.

now i finally understand what you were saying 💀 thank you for your help :)
