[luci] uci state vars not updated using lua library

[Conor O'Gorman]

Hi,

I see differing behaviour between the command line uci tool and the lua
uci functions.

Can someone tell me if this is my error, possibly fixed in an update, or
a better email list to post to?

Here is an strace of both actions. The lua version doesn't even attempt
to write to the state dir. This is on Openwrt backfire x86 in a VM.

strace lua -luci -e 'uci.cursor(nil,"/var/state"):set("httpclient", "default", "active", "y")'
	stat("/var/state/httpclient", {st_mode=S_IFREG|0600, st_size=0, ...}) = 0
	open("/var/state/httpclient", O_RDONLY) = 4
	flock(4, LOCK_SH)                       = 0
	lseek(4, 0, SEEK_SET)                   = 0
	fcntl(4, F_GETFL)                       = 0 (flags O_RDONLY)
	ioctl(4, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfe28840) = -1 ENOTTY (Inappropriate ioctl for device)
	read(4, "", 4096)                       = 0
	flock(4, LOCK_UN)                       = 0
	close(4)                                = 0
	flock(3, LOCK_UN)                       = 0
	close(3)                                = 0
	rt_sigaction(SIGINT, {SIG_DFL, [INT], SA_RESTORER|SA_RESTART, 0xb7712e6f}, {0x8049240, [INT], SA_RESTORER|SA_RESTART, 0xb7712e6f}, 8) = 0
	munmap(0xb7704000, 13016)               = 0
	munmap(0xb76fa000, 37792)               = 0
	_exit(0)                                = ?

strace uci -P /var/state set httpclient.default.active=y
