Subject: [PATCH v7 6/7] convert: add tracing for 'working-tree-encoding' attribute
Date: Thu, 15 Feb 2018 16:27:10 +0100 [thread overview]
Message-ID: <20180215152711.158-7-lars.schneider@autodesk.com> (raw)
In-Reply-To: <20180215152711.158-1-lars.schneider@autodesk.com>
From: Lars Schneider <larsxschneider@gmail.com>
Add the GIT_TRACE_WORKING_TREE_ENCODING environment variable to enable
tracing for content that is reencoded with the 'working-tree-encoding'
attribute. This is useful to debug encoding issues.
