AFAICS ifstat history file handling today assumes all 32 bit stats.
Indeed it does.
And to preserve backward compatibility, new ifstat should work with old and
new history files with 32bit and 64 bit stats.
True.
It may be ok to just provide a conversion tool maybe for taking 32b
history into 64b? I dont know if someone is going to "migrate" their
history files so even that may not be worth it.
The file format cannot be changed because of the same backward compat issues.
So, I am leaning towards a new history file with a new option (maybe ifstat
-64) to
save/query 64 bit stats using the new api when available.
I see some previous brief discussions on moving ifstat to 64 bit.
The other option is to only change 'ip -s link show' to use the new stats api.
let me know if there are other thoughts.
Is it not possible to convert to 64b - and IFLA_STAT
becomes available just store it still in 64b?
i.e 32b will fit in 64b space.
