t/lei-daemon.t failure when PERL_INLINE_DIRECTORY is set

t/lei-daemon.t failure when PERL_INLINE_DIRECTORY is set

[Konstantin Ryabitsev]

While playing with libgit2/Gcf2, I've discovered that t/lei-daemon.t will fail
when PERL_INLINE_DIRECTORY is set:

	t/lei-daemon.t ............... 18/?
	#   Failed test 'connect error noted'
	#   at t/lei-daemon.t line 80.
	#                   ''
	#     doesn't match '(?^:\bconnect\()'
	# Looks like you failed 1 test of 34.
	t/lei-daemon.t ............... Dubious, test returned 1 (wstat 256, 0x100)

I'll be happy to help troubleshoot things, since I don't know how easy it
would be to reproduce this.

I can't seem to reproduce it on my end with CentOS 7 and
libgit2-devel 0.26.8.  Try setting TEST_LEI_ERR_LOUD=1

While poking around, I've discovered that it only fails when "make test" runs
as root (don't judge -- this is in a throwaway lab VM):

	t/lei-daemon.t ............... 1/? # lei_err=/tmp/pi-lei-daemon-6667-ojwj/lei-daemon/xdg_run/lei/errors.log from previous run
	# phail

	#   Failed test 'connect error noted'
	#   at t/lei-daemon.t line 80.
	#                   ''
	#     doesn't match '(?^:\bconnect\()'
	# Looks like you failed 1 test of 34.
	t/lei-daemon.t ............... Dubious, test returned 1 (wstat 256, 0x100)
	Failed 1/34 subtests

When I run as a non-root user, it passes:

	t/lei-daemon.t ............... 1/? # lei_err=/tmp/pi-lei-daemon-11879-P3hC/lei-daemon/xdg_run/lei/errors.log from previous run
	# phail
	# lei_err=connect(/tmp/pi-lei-daemon-11879-P3hC/lei-daemon/xdg_run/lei/5.seq.sock): Permission denied at /home/mricon/public-inbox/blib/lib/PublicInbox/LEI.pm line 1073.
	# lei-daemon could not start, exited with $?=3328
	# connect(/tmp/pi-lei-daemon-11879-P3hC/lei-daemon/xdg_run/lei/5.seq.sock): Permission denied (after attempted daemon start)
	# Falling back to (slow) one-shot mode
	t/lei-daemon.t ............... ok

Hope that helps.

Yes :)

Subject: [PATCH] t/lei-daemon: skip inaccessible socket test as root

"chmod 0000" on a Unix socket can't stop root from connecting to it;
so just skip the test for rare cases when testing as root.

I can confirm that the error is gone now. Thanks!
