Subject: HTTP/2: skip data frames in case of internal errors.
X-Git-Tag: release-1.9.15~2
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=7458f6667530aef24272e5b5dc8815c27b35b05f;p=nginx.git

HTTP/2: skip data frames in case of internal errors.

This prevents possible processing of such frames and triggering
rb->post_handler if an error occurred during r->request_body
initialization.
