Subject: [PATCH] HPack: fix a Yoda Condition
|
|
|
|
Putting the variable on the LHS of a relational operation makes the
|
|
expression easier to read. In this case, we find that the whole
|
|
expression is nonsensical as an overflow protection, because if
|
|
name.size() + value.size() overflows, the result will exactly _not_
|
|
be > max() - 32, because UB will have happened.
|
|
|
|
To be fixed in a follow-up commit.
|
|
|
|
As a drive-by, add parentheses around the RHS.
|
|
|
|
Pick-to: 6.5 6.2 5.15
