[bitbake-devel] [PATCH 0/1] Add a syntax to clear variables and flags from a conf file

[Jérémy Rosen]

From: Jérémy Rosen <jeremy.rosen at openwide.fr>

While working on a Yocto project I had a need to reactivate a task that was
disabled (do_fetch[noexec]="1") Currently, bitbake does not check the value
of the noexec flag but only if the flag is set. The only way to unset a flag
is to use an inline python syntax like the one below

python () {
   d.delVarFlag("do_fetch","noexec")
}

Using inline python to do something as simple as clearing a flag sounded too
complicated to me so I added a new keyword "unset" to bitbake with the
following syntax :

unset VAR

will call d.delVar("VAR")

unset VAR[flag]

will call d.delVarFlag("VAR","flag")

Documentation has been updated accordingly
