From cdf2bc632ebc9ef512345fe8e6015edfd367e256 Mon Sep 17 00:00:00 2001 From: Christian Kujau Date: Fri, 14 Jun 2013 18:04:34 -0700 Subject: scripts/setlocalversion on write-protected source tree I just stumbled across another[0] issue when scripts/setlocalversion operates on a write-protected source tree. Back then[0] the source tree was on an read-only NFS share, so "test -w" was introduced before "git update-index" was run. This time, the source tree is on read/write NFS share, but the permissions are world-readable and only a specific user (or root) can write. Thus, "test -w ." returns "0" and then runs "git update-index", producing the following message (on a dirty tree): fatal: Unable to create '/usr/local/src/linux-git/.git/index.lock': Permission denied While it says "fatal", compilation continues just fine. However, I don't think a kernel compilation should alter the source tree (or the .git directory) in any way and I don't see how removing "git update-index" could do any harm. The Mercurial and SVN routines in scripts/setlocalversion don't have any tree-modifying commands, AFAICS. So, maybe the patch below would be acceptable.
