Subject: Fetch: fixed Headers() constructor.
X-Git-Tag: 0.7.12~10
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=07bea6882969dd75f23c78016bd4b0a0076c146d;p=njs.git

Fetch: fixed Headers() constructor.

Previously, the 'guard' field of ngx_js_headers_t structure was uninitialized,
that caused spurious exception "Error: cannot append to immutable object".

This issue was introduced on 0.7.10.
