Stop responding when syncing

[0000marcell]

App stop responding for a moment after any edit
The problem is related with syncing, when i disable automatic sync it works fine
I love to solve the problem if someone could point me to the right direction

I'm on:
OS: Arch Linux x86_64
Python 3.7.1

Connected fine yesterday, 3/25, last log entries... (Aside: very chatty, is this wss, over https?)

Laptop resumed today, 3/26, the sncli app is responding, opened a note to edit...

2019-03-26 08:55:12,830 [DEBUG] EXECUTING: ['/usr/bin/vim', '/tmp/tmpx98q4bmm.txt']

After saving the updated note...

2019-03-26 09:27:23,201 [DEBUG] Note updated
2019-03-26 09:27:23,205 [DEBUG] Note content updated (key=833d6df8142a11e98c40d18243993991)

That is all, the app simply stops responding.

Meanwhile, I have taken to manually writing to a local tmp file anytime I use sncli. This issue and #82 might be related.

Next steps: will try to run connection management through a python debugger...

No - there are just many requests used during syncing...

Sorry I don't have much time to investigate these issues at the moment. There is a configuration option (cfg_tempdir) that you can set to somewhere persistent that may be helpful in preventing data loss. I'm not sure if or when sncli deletes the temporary file after saving though.

The freezing is almost definitely because of syncing. afaik everything runs in the same thread (or maybe not; urwid might do some magic?), so when a long sync runs, it blocks everything.
