conditional inheriting classes does not work with bbappends

conditional inheriting classes does not work with bbappends

[-- Attachment #1.1: Type: text/plain, Size: 1860 bytes --]

Example: meta-openembedded/meta-networking/recipes-support/chrony/chrony_4.2.bb

--------------------------------8<--------------------------------
# Add chronyd user if privdrop packageconfig is selected
inherit ${@bb.utils.contains('PACKAGECONFIG', 'privdrop', 'useradd', '', d)}
USERADD_PACKAGES = "${@bb.utils.contains('PACKAGECONFIG', 'privdrop', '${PN}', '', d)}"
USERADD_PARAM:${PN} += "${@bb.utils.contains('PACKAGECONFIG', 'privdrop', '--system -d / -M --shell /bin/nologin chronyd;', '', d)}"

...

PACKAGECONFIG ??= ...
-------------------------------->8--------------------------------


Problem #1: useradd is not inherited because PACKAGECONFIG is set below the conditional "inherit"
statement. Even when I add "privdrop" to PACKAGECONFIG here, useradd.bbclass is not inherited. I
must move the PACKAGECONFIG line above the inherit statement to make this work.

Problem #2: Due to problem #1, useradd.bbclass is also not inherited when I add "privdrop" to
PACKAGECONFIG in bbappend file (in a custom layer).

regards
Christian

There’s no way to avoid that, inherit lines are evaluated *at the moment of inherit* on that line, they aren’t postponed.

ok, this is what I would expect. So how to handle this:

- do not conditionally inherit in PACKAGECONFIG (may be impossible)?
- do not set PACKAGECONFIG in bbappend files (use distro/machine/layer/local config for this)?

I don’t think there is a generic solution to this problem. What we do in the particular case is to enable the PACKAGECONFIG in a bbappend and then also add an extra inherit useradd to the bbappend file. Not perfect, but it works.

I have also chosen this workaround. The problem is, that it does not work the other way around:

If the default value for PACKAGECONFIG causes conditionally inheriting specific classes,
these classes will also be inherited if PACKAGECONFIG is overwritten later in a bbappend.

Does the require have the same behaviour as the inherit? i.e: evaluated *at
the moment of inherit*
if not something like that can do the job:

cat <<'EOF' > my.bbappend
PACKAGECONFIG ?= "my-knob"
require ${@bb.utils.contains('PACKAGECONFIG', 'my-knob',
'my-conditional-inheriting.inc', '', d)}
EOF

cat <<'EOF' >my-conditional-inheriting.inc
inherit my.bbclass

Yes, require is evaluated immediately, just like inherit, so unfortunately the suggested example below doesn’t solve the problem either.

-------------------------------->8--------------------------------


Problem #1: useradd is not inherited because PACKAGECONFIG is set below the conditional "inherit"
statement. Even when I add "privdrop" to PACKAGECONFIG here, useradd.bbclass is not inherited. I
must move the PACKAGECONFIG line above the inherit statement to make this work.

Problem #2: Due to problem #1, useradd.bbclass is also not inherited when I add "privdrop" to
PACKAGECONFIG in bbappend file (in a custom layer).

RE: [bitbake-devel] conditional inheriting classes does not work with bbappends

[Diego Santa Cruz]

[-- Attachment #1.1: Type: text/plain, Size: 8692 bytes --]

Hi,

For what is worth I always tweak PACKAGECONFIG values with recipe specific overrides instead of using bbappends. I define those overrides in a distro config or local.conf.

For instance

PACKAGECONFIG:pn-p11-kit ?= "trust-paths"

That should solve your problem.

I only use bbappends when some of the logic in the recipe needs to be tweaked, not when the configuration which is already supported by the base recipe needs to be adjusted.

Best,

Yes, require is evaluated immediately, just like inherit, so unfortunately the suggested example below doesn’t solve the problem either.

Hi

Christopher Larson <kergoth@gmail.com<mailto:kergoth@gmail.com>> escreveu no dia quinta, 7/04/2022 à(s) 22:59:
There’s no way to avoid that, inherit lines are evaluated *at the moment of inherit* on that line, they aren’t postponed.

Does the require have the same behaviour as the inherit? i.e: evaluated *at the moment of inherit*
if not something like that can do the job:

cat <<'EOF' > my.bbappend
PACKAGECONFIG ?= "my-knob"
require ${@bb.utils.contains('PACKAGECONFIG<mailto:$%7b@bb.utils.contains('PACKAGECONFIG>', 'my-knob', 'my-conditional-inheriting.inc', '', d)}
EOF

cat <<'EOF' >my-conditional-inheriting.inc
inherit my.bbclass
EOF
