tmux.conf invalid settings problem

[VegaDeftwing]

Not sure what the issue is really. I tried seeing if for some reason turning off firewalld and disabling all my adblockers and other extensions. Failing that, I tried opening it in Chromium, with the same result.

Firefox gives a similar error "Firefox can’t establish a connection to the server at ws://127.0.0.1:5552/." with the issue again being in the main .js file on line 509. , so it's clearly browser agnostic and other local services like Netdata run fine.

Can you provide ./gdbfrontend output and output for tmux a -t gdb-frontend?

[VegaDeftwing]

even starting ./gdbfrontend with -V doesn't yield any more useful output really

Each of those 'GET /' lines is from refreshing the page in Chorme/Vivaldi/Firefox

[rohanrhu]

What is your tmux version and which OS are you using?

[jibanes]

I have the same issue on debian 9 running tmux 2.3

[VegaDeftwing]

Arch Linux 5.5.4 , tmux 3.0_a-1

[rohanrhu]

Try updating tmux to 2.8 at least or empty tmux.conf content. I will add a check tmux version check for fallback

[rohanrhu]

Arch Linux 5.5.4 , tmux 3.0_a-1

Very interesting.. clean your tmux.conf until the solution.

I'm no longer at that desktop, I was only able to confirm those version numbers because my laptop is on Arch too. I'll let you know if cleaning the tmux.conf fixes things when I get home in ~3 hours.

[jibanes]

I have no ~/.tmux.conf , same problem.

[rohanrhu]

I have no ~/.tmux.conf , same problem.

It has its own tmux.conf: https://github.com/rohanrhu/gdb-frontend/blob/master/tmux.conf

Clean its content but don't remove the file.

[jibanes]

I cleared tmux.conf I get popups "Connection closed to GDBFrontend server!" on 5551, closing that box makes a new one appear gdb is "running" in 127.0.0.1:5550

[VegaDeftwing]

Tried it from my laptop, same "Connection Closed Message" even if tmux.conf in the gdb-frontend folder is cleared here as well

The Tmux session does open now:

I think carriage returns may occur this problem but im not sure.

The Tmux session does open now:

I have not tested GDB 9 yet. I will look that.

[VegaDeftwing]

That didn't appear to do anything. Tmux is working fine from what I can tell. Intreguringly, on the laptop I'm getting a bit more output, despite getting the same error in the browser, this is regardless of what's in the tmux.conf file. Also, on the laptop, for no apparent reason, if I go to 127.0.0.1:5551/terminal, the terminal does load briefly now (this is dependent on tmux.conf) but I still get the connection error message and the page gives me no choice but to reload

[VegaDeftwing]

I'd imagine that's our problem. I'll see if I can install 8 and point it to use it. Gimme a bit

[rohanrhu]

Can you paste outputs for these commands on GDB shell?

shell echo $CWD python import sys;print(sys.version) python print(dir(server))

[VegaDeftwing]

I just tried downgrading to 8.3.1, no change. Putting them back up to 9. shell echo $CWD gives no output

(gdb) python import sys;print(sys.version)
3.8.1 (default, Jan 22 2020, 06:38:00) 
[GCC 9.2.0]

(gdb) python print(dir(server))
Traceback (most recent call last):

[rohanrhu]

Did you try python print(dir(server)) on tmux gdb-frontend session?

[VegaDeftwing]

Did you try python print(dir(server)) on tmux gdb-frontend session?

Not above, but I just did and the output is exactly the same

[VegaDeftwing]

Strangely, in the tmux session I can't even do the print(sys.version),

[rohanrhu]

Strangely, in the tmux session I can't even do the print(sys.version),

print() is python function like python import sys;print(sys.version)

[rohanrhu]

Did you try python print(dir(server)) on tmux gdb-frontend session?

Not above, but I just did and the output is exactly the same

Can you paste these outputs? python import os;print(os.getcwd()) python import server;print(dir(server))

ope, my bad. Currently in class so trying to listen and type at the same time. It does print in the tmux session:

[rohanrhu]

It seems that file is a different file from https://github.com/rohanrhu/gdb-frontend/blob/master/server.py

Can you paste this output? python import server;print(server.__file__)

[VegaDeftwing]

Yep, you're right. It's using /usr/lib/python3.8/site-packages/server.py

[VegaDeftwing]

cant test it to really confirm right now, (laptop is about to die) but that does seem to have worked!

[rohanrhu]

Im sorry for your laptop :/ Did https://github.com/rohanrhu/gdb-frontend/commit/6c9723ad6f0ac5897c30197e6e68bec26ea1676e solve the tmux issue?

[VegaDeftwing]

Battery died, so responding from email on phone. Yes, that fixed the tmux problem.

Can we close this issue?

[VegaDeftwing]

Yeah, didn't actually realize it wasn't already. My bad.
