Subject: [PATCH v5 5/7] git-p4: check free space during streaming
Date: Mon, 14 Sep 2015 15:26:32 +0200 [thread overview]
Message-ID: <1442237194-49624-6-git-send-email-larsxschneider@gmail.com> (raw)
In-Reply-To: <1442237194-49624-1-git-send-email-larsxschneider@gmail.com>
From: Lars Schneider <larsxschneider@gmail.com>
git-p4 will just halt if there is not enough disk space while
streaming content from P4 to Git. Add a check to ensure at least
4 times (arbitrarily chosen) the size of a streamed file is available.
