Subject: Fix regression in 2.9 involving unsafe Context.get_all() usage
X-Git-Tag: 2.9.x~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=60a7e775d487c8de9f1b0f23c91ca9845c161fc2;p=thirdparty%2Fjinja.git

Fix regression in 2.9 involving unsafe Context.get_all() usage

Since commit d67f0fd4cc2a4af08f51f4466150d49da7798729, callers
of Context.get_all() need to make a copy it they're going to
modify the result.

Fixes: d67f0fd4cc2a ("Generalize scoping.  This fixes #603")
