[bitbake-devel] hashequiv, pseudo, and GIDs

[chris.laplante at agilent.com]

Hello all,

I'm encountering a failure like below when using hashequiv. What is happening is recipe "A" is installing some files in do_install, and changing the group of those files. The group is defined by a different recipe ("B"). There is no dependency between A and B, so when A:do_package runs, the group is not present in A's pseudo database. OEOuthashBasic tries to lookup the owning group name of the file, and a KeyError is raised.

A workaround is to add:
    DEPENDS += "B"
to recipe A, so that the group ends up in A's pseudo database. This works, but seems really really hacky, since it's only necessary when hashequiv is active.

So why is the group name used in the hash, as opposed to the GID? (I also have the same question regarding user name vs UID). If the GID was used we wouldn't have this issue.

Thanks,
Chris
