Package: i3lock
Version: 2.8-1
Severity: minor

Dear Maintainer,


i3lock can show the number of failed attempts using the -f flag. If
the number of failed attempts is higher than 999, it shows “>999” –
but the value shown was “1” again, after I manually incremented the
value saved in i3lock memory to 2^32-1 and entered a wrong password
again. I think one can duplicate this pretty easily using scanmem …

To be clear, I expected the amount of failed attempts to be “>999”,
without any wraparound behaviour. Note that the man page for i3lock
does not contain a description of “>999” behaviour for the -f flag.

I chose “Severity: minor” since it looks like a cosmetic bug to me.
