Not working on Xubuntu Linux

[dflock]

I'm going to preface this by saying thank you very much for making this - I'm very excited for this Tabfs and I'd love to get it working!

I followed the install instructions, afict, but tabfs doesn't appear to work for me:

$ git clone https://github.com/osnr/TabFS.git

In the console of the extension's background page, it says this:

I was expecting the make to do something... more than that, maybe? Although it does seem to have built fs/tabfs:

$ pwd

What can I do to help debug & figure this out?

[osnr]

hmm. that all looks OK... can you run the binary fs/tabfs directly from the shell and tell me what output you get?

[dflock]

$ ./tabfs 

Usage:
 kill [options] <pid> [...]

Options:
 <pid> [...]            send signal to every <pid> listed
 -<signal>, -s, --signal <signal>
                        specify the <signal> to be sent
 -l, --list=[<signal>]  list all signal names, or convert one to a name
 -L, --table            list all signal names in a nice table

 -h, --help     display this help and exit
 -V, --version  output version information and exit

For more details see kill(1).

It didn't work for me neither until I created the fs/mnt directory via mkdir.

It didn't work for me neither until I created the fs/mnt directory via mkdir.

I did that as part of the original install.

I'm having the same issue with Chrome in a CentOS docker container. I had to add this to the CFLAGS_EXTRA in the makefile to get it to compile: -std=c99 -D_POSIX_C_SOURCE=200112L

When I run ./tabfs it just sits there without returning. My log.txt file is empty.

[osnr]

Hmm. It's hard to say what exactly is going wrong if fs/tabfs doesn't obviously crash on startup (it's really only meant to be run by the browser; we're just running it from the shell here as a quick check).

You could maybe run gdb in a mode where it waits to attach to the tabfs process when it appears, then reload the extension in the browser (which starts the tabfs process) and try to catch why it's terminating.
