Subject: Fixed Priority parsing of large integers on 32-bit platforms
X-Git-Tag: release-1.31.8~10
X-Git-Url: https://git.kaiwu.me/?a=commitdiff_plain;h=82f5fd93b99bc3e0fcdb7532ea181a36571d5407;p=nginx.git

Fixed Priority parsing of large integers on 32-bit platforms

On 32-bit platforms, ngx_atoi() fails on syntactically valid Integers
above 2147483647, and the whole Priority field was rejected.  Now such
values are ignored, similar to Decimals.
