From 7b64469a363c10e9e875a73d32a220ba48694a28 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Mon, 19 Apr 2010 07:23:08 -0700 Subject: [PATCH] Allow parse_pack_index on temporary files The easiest way to verify a pack index is to open it through the standard parse_pack_index function, permitting the header check to happen when the file is mapped. However, the dumb HTTP client needs to verify a pack index before its moved into its proper file name within the objects/pack directory, to prevent a corrupt index from being made available. So permit the caller to specify the exact path of the index file. For now we're still using the final destination name within the sole call site in http.c, but eventually we will start to parse the temporary path instead. Signed-off-by: Shawn O.
