Subject: Fixed ngx_http_parse_chunked() minimal length calculation.
X-Git-Tag: release-1.5.2~1
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=88fc0f793e6ba4a7ece20f43fcd4357df1231f00;p=nginx.git

Fixed ngx_http_parse_chunked() minimal length calculation.

Minimal data length we expect for further calls was calculated incorrectly
if parsing stopped right after parsing chunk size.  This might in theory
affect clients and/or backends using LF instead of CRLF.

Patch by Dmitry Popov.
