Bug ID: 495859
Summary: neochat room info json cache files fail to be written
to disk when they contain wild characters, corrupting
cache
Classification: Applications
Product: NeoChat
Version: 24.08.2
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: fe...@posteo.de
Reporter: orangewi...@gmail.com
CC: c...@carlschwan.eu
Target Milestone: ---
SUMMARY
neochat tries to keep room info on disk in json files, but (apparently) cannot
write the entire spectrum of valid file names
STEPS TO REPRODUCE
1. join https://matrix.to/#/#test:maunium.net
I did this from element and neochat was not open when it happened. Neochat was
not open for a month or so before trying to sync this room using the reported
version of neochat. I don't know if this matters, I am just noting it.
2. open neochat
3. neochat reports corrupted cache and doesn't function well.
OBSERVED RESULT
Nov 05 17:42:34 sakura neochat[57173]: quotient.main: Error opening
"/home/aranjedeath/.cache/KDE/neochat/@aranjedeath_explodie.org/!#test/room\nversion
<u>11</u>, with @🐈_maunium.net.json" : "No such file or directory"
EXPECTED RESULT
neochat does not corrupt own cache and have a panic about it, and ideally
supports emojis, vertical spaces, and other such weird but valid characters
that can be present in room names.

ADDITIONAL INFORMATION
the room shows up in neochat, and you can generally view posts. if you try to
touch room settings or any of those buttons (which I suspect would try to read
the non-existent json file for the room), it crashes.
After that crash, startup reports this:
Nov 05 18:07:26 sakura neochat[63931]: quotient.main: Unresolved rooms:
"!#test/room\nversion <u>11</u>, with @🐈:maunium.net"
Nov 05 18:07:26 sakura neochat[63931]: quotient.main: No state cache file
"/home/aranjedeath/.cache/KDE/neochat/@aranjedeath_explodie.org/!#test/room\nversion
<u>11</u>, with @🐈_maunium.net.json"
This shows the crash itself from tapping the room settings button
