Hi All,
This issue could be reproduced only by building multilib packagegroup
package in the first time. [YOCTO #5532]
*Step:
1) bitbake packagegroup-core-nfs-server
2) bitbake lib32-packagegroup-core-nfs-server
Only the first time to do the build has this issue:
...
WARNING: The recipe lib32-packagegroup-core-nfs is trying to install
files into a shared area when those files already exist. Those files
and their manifest location are:
/home/jiahongxu/yocto/build-20131120-yocto-qemux86-64/tmp/deploy/rpm/all/packagegroup-core-nfs-server-1.0-r2.all.rpm
Matched in manifest-allarch-packagegroup-core-nfs.deploy-rpm
There are two types of 'packagegroup' packages. Ones that are specific to an
architecture (or machine), and one that are 'all' packages.
All packages in indeed generic and should not have references to 'lib32' or
specific other package types on RPM.
*Analysis:
- The following commit message is the background which come

[YOCTO #4532] Mark Hatle
In deb/ipk on a multilib package, the package name has specific
multilib
references in it. I.e. the alternative libraries start with something
like lib32-... This was done primarily because deb/ipk do not
allow two
packages with the same name (but different architectures) to be
installed at the same time. So the name has to be unique.
In RPM however, the names of the packages and matches with the
architectures and if they are not the same we can do these multilib
installs.
- For this rpm multilib packagegroup issue, the multilib and non-multilib
packages have the same name 'packagegroup-core-nfs-server', and
the same architectures 'all'.
This is correct. For a packagegroup that only wants generically named
functionality (and all package) then we could end up trying to generate two of
them...
*Solution
- One possible fix is as Mark Hatle suggested simply to follow the
deb/ipk package
naming, but this causes a design advantage of rpm. When a package has a
dependency on 'bash', we really don't care what bash is installed, only
that -a-
bash is installed. In the deb/ipk case, the lib32- packages would end
up with a
lib32-bash dependency and you could potentially end up with two 'bash'
packages
being installed.
Yes, we want to avoid that unless we find there simply is no other way. One
possible fix (using the above approach), if this is an 'all' package, and we're
not in the primary multilib, we could simply skip the package_write_rpm step.
This may prevent the warning and will avoid repackaging things unnecessarily.
We only want to do this for 'all' types, and not for a tune or machine type, as
those are allowed to have specific architectural references in them.
- Tweak oe-core commit 1674541ed83fa4645f2e078f65fe0f878527ee6e
'multilib: fix allarch/kernel/module-base multilib issues', skip the
packagegroup
allarch recipes in multilib_virtclass_handler and extend PROVIDES/RPROVIDES
for packagegroup allarch recipes. It will not build the multilib
packagegroup allarch
recipes if the same packagegroup allarch recipes has already been built.
But I think it's a bad idea, the previous packagegroup allarch check is
reasonable.
In this case, it would likely break deb and opkg. Even though we don't use
them, I still don't want to break them unintentionally.
- We could simply add PACKAGE_ARCH = "${MACHINE_ARCH}" in each
packagegroup allarch recipe to avoid the QA Warning, but it actually
doesn't work
at the image do_rootfs time, the smart could not correctly find the RDEPENDS
between multilib and non-multilib packagegroup packages.
- Is it necessary to fix the multilib packagegroup issue, it seems the
warning
occurs on the world building, we rarely build both of the multilib and
non-multilib
for one package at the same time , we could simple tweak the sanity check
to ignore the warning.
It is a warning that really doesn't cause a problem. Tweaking the sanity check
is another option -- but the actions of the system are incorrect. It should
know for RPM that we're not REALLY rebuilding the packagegroup, and not
repackage it.
If we were to modify the sanity check, then we should change it to verify what
has been installed already, and what is about to be installed/overwritten have
the same contents. If the contents differ, then it's still a warning.
Otherwise we could silently ignore the warning for our customers (and try to
resolve this in the community for WR 7, if it's still an issue there.)
Any suggestion is welcomed.
For WR 6, either we should:
Adjust the package generation to avoid generating 'all', secondary multilib
packages using rpm.
or
Adjust the sanity check to verify the second package overwriting the first has
the same contents. [Specifically package set.]
