Spyder 5.1.1 freezes trying open file

Zincr0 commented 3 years ago

Problem Description

Spyder completely freezes when clicking open file.

What steps reproduce the problem?

Install the latest miniconda (python 3.9).
Install spyder 5.1.1 from conda-forge:
Click on open file.

What is the expected output? What do you see instead?

Spyder should show the file browser.

Spyder window completely freeezes, no log on terminal, no errors, no anything. The only possible thing to do is killing the process.

"spyder --safe-mode" changes nothing. "spyder --reset" changes nothing. Removing the entire .config/spyder-py3 folder changes nothing.

Spyder version: 5.1.1
Python version: Python 3.9.5 64-bit

Your environment has a mix of conda-forge and defaults package, which is a really bad thing to do because those packages are (for the most part) binary incompatible. I think that's the cause of the odd error you're seeing.

So please try again by creating a new environment from scratch with the following commands:

conda create -n new-env -c conda-forge spyder
conda activate new-env
spyder

Ok I found a way to recreate the bug, with the kio-fuse package installed:

create a sftp network folder using dolphin.
mount the folder (dolphin does this automatically when clicking and opening the folder).
in spyder, open some file from the remote mounted folder and edit it. It will work just fine (on dolphin, pressing F4 will show the console and the full path of the mounted folder).
close all the files, and close spyder.
change to another network or switch to a VPN that cannot reach the old remote machine.
open spyder and click the "open file" icon. The default work directory should open, which is a local directory and has no relation to the previuos remote mounted folder, instead, spyder will hang forever.
On the clean conda-forge only environment, restarting the computer fixes the problem.

Tested on both, mixed and conda-forge only environment.

Edit: I mean, is a workaround, rebooting the entire pc just to open a different file is a little too much.

Edit 2: better steps to reproduce the problem.

ccordoba12 commented 3 years ago

Thanks for letting us know how to reproduce this problem. We simply use the default open dialogs provided by Qt/PyQt, so I'd say it's a problem with them.

I understand this is a very annoying bug, but we're a small team and this seems like a very fringe case. So it's very low priority for us, sorry.

Zincr0 commented 3 years ago

If you leave some hints here about what and where to look, maybe i can find a better workaround or even tweak some code

ccordoba12 commented 3 years ago

You can take a look at the load method of the Editor class in spyder/plugins/editor/plugin.py:

https://github.com/spyder-ide/spyder/blob/cb346166a713dcf8e2278951c5ddc96e8337d203/spyder/plugins/editor/plugin.py#L2063-L2077

ccordoba12 commented 3 years ago

The function getopenfilenames in that method is the one we use to show an open dialog to users.

On Fedora 36/Gnome when you try to open a file a system notification comes down from the the top center of the screen. It has a title Portal and says "Open file" is ready. Clicking on that will make the file browser appear. Before that, the file browser is created behind the main window. Since the user doesn't know the file browser is behind the main window, and it's blocking input to the main window, the program appears to be frozen.

ccordoba12 commented 2 years ago

@derek-v-s, problems with Linux distros need to be reported with them because we don't have control on the way they package Spyder and its dependencies.

If you want to avoid that error, please install Spyder in a virtualenv with pip or download Anaconda/Miniconda.
