[bitbake-devel] [PATCH 1/1] toaster: noweb should init database

[David Reyna]

From: David Reyna <David.Reyna at windriver.com>

When the 'noweb' option for Toaster is used, perform the database
check/create if the Toaster database does not yet exist.

This will allow Toaster to not fail if the first use is with 'noweb'.
This avoids potentially clashing database updates if there are
multiple overlaping 'noweb' sessions (for example with a CI system).

If the user wished to update the database, they can either use the
explicit "lsupdate" command or (re)start a web hosted Toaster session
(which is gated by the webserver's PID).

[YOCTO #11378]
