[lvm-devel] Fwd: [linux-lvm] LVM2.2.02.103/tools/lvchange.c:779: bad if test ?



And the && is wrong as well.
So || instead of && and inside braces &&s instead of ||s.

Now it matches anything /[^:].$/ but I believe it was intended to be /[^:].$|:[tyn]$/ which is wrong too but in fact should be /[^:].$/ so it is in fact weirdly written correct implementation. =8-O

I wonder, is it possible to have the PV matching /:[^tyn]$/?
In such case it is, then /:[tyn]$/ should be valid as well, shold not it?

I suggest:

if /[^:]./:
    - add default
else if /:[^tyn]$/
    - should be internal error
    - recovery: last character should be _replaced_ by default
else # /:[tyn]/
    - NOP

Hello there,

I just compiled LVM2.2.02.103 with the extra Linux gcc compiler
flag -Wlogical-op

It said

lvchange.c:779:10: warning: logical 'or' of collectively exhaustive tests is always true [-Wlogical-op]

Source code is

                 ((tmp_str[tmp_str_len - 1] != 't') ||
                  (tmp_str[tmp_str_len - 1] != 'y') ||
                  (tmp_str[tmp_str_len - 1] != 'n'))))

Suggest swap || for &&

Regards
