Subject: SSL: handled long string truncation in ngx_ssl_error().
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=645697f111983089fdcee0694d17480e0a05a3a5;p=nginx.git

SSL: handled long string truncation in ngx_ssl_error().

If no space left in buffer after adding formatting symbols, error message
could be left without terminating null.  The fix is to output message using
actual length.
