Skipping network-required recipes automatically?

Skipping network-required recipes automatically?

Hi all,

My layer has a bunch of "development" recipes that contain something like:

PV = "1.1.2+git${SRCPV}"
SRCREV = "${AUTOREV}"
DEFAULT_PREFERENCE = "-1"


In these cases, my recipes have a "known good" version that has a specific
known-good version number (recipe_1.1.2.bb), and then the "recipe_git.bb"
file that I only enable using PREFERRED_VERSION when I'm wanting to use the
latest source code.

My problem with this is that it seems to defeat BB_NO_NETWORK, and I'm not
sure how to handle it. I would like my layer to work correctly with no
network, but the mere presence of these development recipes causes my build
to fail during parsing if the network is not available.

My last failed attempt was to create a "skip-git" class that I inherit in
local.conf with the following:

python () {
    no_network = d.getVar('BB_NO_NETWORK')
    pn = d.getVar('PN')
    pv = d.getVar('PV')

    if no_network and 'git' in pv:
        raise bb.parse.SkipRecipe("Recipe requires git, but no network:
%s-%s" % (pn, pv))
}


Unfortunately, bitbake seems to fail in data_smart.py before my class
actually has a chance to skip the recipe even in this case.

Is there a better way to handle this?

Thanks,
Aaron

you might add PREFERRED_VERSION to select the given recipe, in that
case recipe in your layer should have different version than the
original one. Then you can do something like

python () {
    if d.getVar("PREFERRED_VERSION_<pn>") != d.getVar("PV"):
        d.delVar("BB_DONT_CACHE")
        raise bb.parse.SkipRecipe("Skip it")
}


not too sure if it will ignore it. 

another option is to look at devupstream.bbclass it might have some
ideas for you.
