Subject: [PATCH 1/2] builtins: do not commit pager choice early
Date: Thu, 25 Mar 2010 20:38:14 +0700	[thread overview]
Message-ID: <1269524295-24569-1-git-send-email-pclouds@gmail.com> (raw)

From: Duy Nguyen <pclouds@gmail.com>

Committing pager choice may require setting up the pager, which
will need access to repository.

At the time after handle_options() is called, the repository has not
been found yet. As a result, unallowed access to repository may
happen.

There are several possible code path after
handle_options()/commit_pager_choice() is called:

1. list_common_cmds_help()
2. run_argv()
3. help_unknown_cmd()

Case 2. will have commit_pager_choice() called inside run_builtin() if
a command is found. Case 1. and 3. won't need a pager, it's short
printout and should be fitted within a screen. So, removing
commit_pager_choice() call after handle_options() is safe.

 On top of nd/setup. This may help fix the breakage in t7006. And forget t9100
 breakage I mentioned elsewhere. My system is broken, git-svn dies when it "exit 0;"
 and even git one year ago does not fix it.
