From 0454dd93bfb2334355ec62fff670d8c6cb3570a1 Mon Sep 17 00:00:00 2001 From: David Reiss Date: Mon, 19 May 2008 23:49:26 -0700 Subject: Add support for GIT_CEILING_DIRECTORIES Make git recognize a new environment variable that prevents it from chdir'ing up into specified directories when looking for a GIT_DIR. Useful for avoiding slow network directories. For example, I use git in an environment where homedirs are automounted and "ls /home/nonexistent" takes about 9 seconds. Setting GIT_CEILING_DIRS="/home" allows "git help -a" (for bash completion) and "git symbolic-ref" (for my shell prompt) to run in a reasonable time.
