Broken Pipe

anklebreaker opened this issue 3 years ago · comments

Quick question, was getting a broken pipe message when running the tuna command. The tab opens up in browser but is unable to connect. Any idea on the cause?

Exception happened during processing of request from ('127.0.0.1', 63304)

I'm getting a similar error while using tuna 0.5.9 + python3.8 + Chrome 93.0.4577.63 + Ubuntu 18.04:

Same here :( My .prof file is 1.9M, not sure if this could be caused by too much data

Vincent Schoener · Answer 5 · Wed Mar 30 2022 22:36:26 GMT+0800 (China Standard Time)

Same error on my side. 2.9 MB for the file. Seems maybe too complicated to handle using a request?

I came to tune after hitting this limitation of snakeviz -- thanks for filing that issue btw!

When loading a large-ish .prof file (2.9MiB), the browser tab crashes (out of memory?). I think the "Broken Pipe" is a consequence of the tab crashing, not the cause of it. FWIW, I tried it both with a recent Brave and Firefox. Same thing in both browsers.

A smaller .prof file (1MiB) loads OK, although it seems to bog down the browser quite a bit.

Tuna: version 0.5.11
Brave: Version 1.39.122 Chromium: 102.0.5005.115 (Official Build)
Python 3.8.12

Unfortunately unusable with my sample on 2.3 MiB of traces with the same symptom -- browser tab crashing and breaking the connection. It is able to render another sample with 700 KiB of data though.

Tuna: 0.5.11
Python: 3.10.6
OS: macOS 13.6.1

same issue here, i got files of ~3MB. any idea how to get around this?

I think this issue is caused by the giant graph data generated in the HTML file. I tried with a 2.1MiB trace file and the browser crashed. I used wget to download the page directly, and the downloaded HTML file is as huge as 663MiB. It has 64 lines and one of them is an incredibly long x-icicle data. Even vim is struggling with opening this file.

Not sure if format the x-icicle data into multiple-lines would help with this issue, or probably it needs interactive partial loading like snakeviz?
