IndexError: list index out of range

[ghost]

After running python -m birdseye.clear_db and executing the program again, I'm now getting this exception when I click on a function from the front page.

birdseye 0.8.1 python 3.6.5 ubuntu 18.04

Restart the server and refresh the home page in the browser.

[ghost]

I did, no change. This is with import birdseye.trace_module_deep

[alexmojaki]

1. Stop all running python programs, including the birdseye server. Verify none are running with ps aux | grep python.
2. Close all birdseye browser tabs.
3. Verify that visiting http://localhost:7777 now results in an error.
4. Run python -m birdseye.clear_db.
5. Delete ~/.birdseye.db for good measure.
6. Start birdseye server.
7. Verify that visiting http://localhost:7777 now results in a page with no calls or functions.
8. Run the program.
9. Refresh the home page.

If you still get the error, please share:

1. A screenshot of your home page.
2. The exact thing that you're clicking on.
3. Code that reproduces the error.

Right now I don't have enough information to reproduce this.

I reproduced on another computer. The error occurred if I click on a link, go back to homepage, 4 times.

Homepage looks like:

cata.py s fm cat cf Execution of module

Code:

import birdseye.trace_module_deep

def fm(f, data):
    if isinstance(data, list):
        return [f(x) for x in data]
    return data

def cat(f, data):
    def cf(x):
        return cat(f, x)
    return f(fm(cf, data))

def s(data):
    if isinstance(data, list):
        return sum(data)
    return data

values = [[[1, 2], [20]], [300]]
result = cat(s, values)
print(result)

Thanks for your efforts! I appreciate you taking the time to figure this out with me.

Unfortunately I still can't reproduce it with any amount of clicking, using that exact code and my homepage looking just like that.

Please share the exact actions. Which link are you clicking? Does going back to the homepage mean clicking the browser back button?

Once you see the error, what does it take to make it go away?

Is it always that same traceback?

Is Flask showing any other logs? Can you share them?

[ghost]

I've reproduced on a server I can provide access to if you'd like to investigate further. Perhaps the simplest way is if you'd like to share an ssh public key I can authorize it and post the connection info.

[alexmojaki]

Awesome! Here you go:

Birdseye is currently executing in a virtualenv. Please try ssh user@46.101.144.229

[alexmojaki]

This is how all bug reports should be done!

I've found the problem, it's about absolute paths and tracing modules. Will push out a fix soon.

Thanks again.

[alexmojaki]

OK, upgrade and give it a go.

Works great, thanks!
