[OE-core] util-macros.do_package failed Re: Build failure

[Robert Yang]

Hi Andreas,

I met the error on the master, we seldom met this error, but we did meet
it once in a while, I did several rough investigations, I think that the
problem is happened when etc/passwd is being created but is null before
write anything into it, and the util-macros.do_package runs right at the
same time, here is a hack way to reproduce it: (Use qemux86 as an example):

$ bitbake base-passwd

# Move the passwd file
$ mv tmp/sysroots/qemux86/etc/passwd tmp/sysroots/qemux86/etc/passwd.bak

# Create a passwd file which is null
$ touch tmp/sysroots/qemux86/etc/passwd

$ bitbake util-macros

Then we will see the errors.

The build is be OK if there is no tmp/sysroots/qemux86/etc/passwd, maybe
the pwd.getpwnam() reads the host's /etc/passwd when there is no
tmp/sysroots/qemux86/etc/passwd (not sure about this). but it would fail
if it exists and is null.

Maybe we can let the do_package depend on base-passwd:do_populate_sysroot
to fix the problem.

Will do more investigations tomorrow.

Night.

// Robert
