Subject: [PATCH 23/35] attr.c: always pass check[] to collect_some_attrs()
Date: Thu, 10 Nov 2016 12:34:16 -0800 [thread overview]
Message-ID: <20161110203428.30512-24-sbeller@google.com> (raw)
In-Reply-To: <20161110203428.30512-1-sbeller@google.com>
From: Junio C Hamano <gitster@pobox.com>
This function used to be called with check=NULL to signal it to
collect all attributes in the global check_all_attr[] array.
Because the longer term plan is to allocate check_all_attr[] and
attr_stack data structures per git_attr_check instance (i.e. "check"
here) to make the attr subsystem thread-safe, it is unacceptable.
Pass "Are we grabbing all attributes defined in the system?" bit as
a separate argument and pass it from the callers.
