inotify_rm_watch: Invalid argument
I tried to test out fswatch with the following simple command:
fswatch -0 test | xargs -0 -n1 echo "Hello"
After each response
Hello /home/JacobAMason/test
I get the following
inotify_rm_watch: Invalid argument
Hello
This happens on every update to the file. So I have this output:
fswatch -0 test | xargs -0 -n1 echo "Hello"
Hello /home/JacobAMason/test
inotify_rm_watch: Invalid argument
Hello
Hello /home/JacobAMason/test
inotify_rm_watch: Invalid argument
Hello
Hello /home/JacobAMason/test
inotify_rm_watch: Invalid argument
Hello
...
Any idea what could cause this? I'm running fswatch 1.11.2 on Archlinux.
Hi @JacobAMason, thanks for the report. I'll have to investigate it. Could you dump the directory structure of the test directory and all its contents and attach them to this issue?
$ find test -type d > directories.txt
$ find test > contents.txt
I also just ran into this issue, while using fswatch on a rasPi.
My workaround was to switch the monitor that I was using:
fswatch -m poll_monitor
You can find the list of available monitors by using the -M flag:
pi@raspberrypi:~/csound/hello_world $ fswatch -M
inotify_monitor
poll_monitor
pi@raspberrypi:
Here is my output when I do not switch monitors:
pi@raspberrypi:~/csound/hello_world $ fswatch -0 pluck.csd
/home/pi/csound/hello_world/pluck.csdinotify_rm_watch: Invalid argument
Here is my output when I do switch monitors:
pi@raspberrypi:~/csound/hello_world $ fswatch -m poll_monitor -0 pluck.csd
/home/pi/csound/hello_world/pluck.csd
Closing this because there's no way to replicate this issue and there's no feedback from the issuer.
Sorry to reopen this, but I can confirm that this is an issue:
I run fswatch with inotify_monitor and then modify index.php:
fswatch -m inotify_monitor -t -x /path/*.php
Mon 04 Feb 2019 09:56:32 PM UTC /path/index.php Updated
inotify_rm_watch: Invalid argument
Mon 04 Feb 2019 09:56:33 PM UTC AttributeModified
I run fswatch with poll_monitor and then modify index.php and it stops happening:
fswatch -m poll_monitor -t -x /path/*.php
Mon 04 Feb 2019 09:57:50 PM UTC /path/index.php Updated AttributeModified
To confirm it's not something to do with my command line, I removed everything (so it should default to inotify_monitor) and it happens again:
fswatch /path/*.php
/path/index.php
inotify_rm_watch: Invalid argument
As for index.php, it's a regular file. Nothing special about it, or the path:
-rw-rw-r--+ 1 root root 26 Feb 4 22:02 index.php
I'm facing the same issue.
fswatch -0 **/*.php | while read -d "" event; do echo ${event}; done
/home/eddie/Workspace/COMPANY/projects/PROJECT/app/FILEPATH/FILENAME.php

I thought it was something related with file names but according to @Jammmmm that's not the case. Would anyone attach a zipped directory I can use to replicate this problem? I haven't been able to replicate it and until I do there's no way I can fix it.

There's nothing special about it. Standard directory with standard file.
I've tried running fswatch as a regular user and as root. Both have the problem.
I have just noticed that @Eluminae is using Ubuntu. I am too. Maybe that has something to do with it?

Checked out sources with version 1.13.0 and locally built it. That seems to work fine.
I got the same thing on archlinux, sadly.

Ditto. Seem to only get the output on renames of the watched file. There's only two calls to inotify_rm_watch in inotify_monitor.cpp so it shouldn't be too hard to figure out what is happening. Will try to make a patch when I have a chance.
