From: Philip Oakley Date: Sun, 22 Jan 2017 19:52:59 GMT Subject: [PATCH v3 2/4] git gui: cope with duplicates in _get_recentrepo Message-ID: <20170122195301.1784-3-philipoakley@iee.org> In-Reply-To: <20170122195301.1784-1-philipoakley@iee.org> _get_recentrepo will fail if duplicate invalid entries are present in the recentrepo config list. The previous commit fixed the 'git config' limitations in _unset_recentrepo by unsetting all config entries, however this code would fail on the second attempt to unset it. Refactor the code to pre-sort and de-duplicate the recentrepo list to avoid a potential second unset attempt.
