From a5db4b127bf86b9dbeb3cb079f4a9530ba313941 Mon Sep 17 00:00:00 2001 From: Lars Schneider Date: Sat, 26 Sep 2015 09:55:03 +0200 Subject: git-p4: add support for large file systems Perforce repositories can contain large (binary) files. Migrating these repositories to Git generates very large local clones. External storage systems such as Git LFS [1], Git Fat [2], Git Media [3], git-annex [4] try to address this problem. Add a generic mechanism to detect large files based on extension, uncompressed size, and/or compressed size.
