So we record METADATA_REVISION in eSDK generation time to fix this problem.

I have to wonder why base-files is depending on the metadata-revision? That
implies that base-files and hence anything that depends upon it would rebuild
each time you update to a new revision. Is that really what you want?

Hi Richard,

I tested it on pure yocto project. No extra layer or configuration.
I'm also wondering why base-files do_install depends on METADATA_REVISION. The strange thing is that things do not rebuild at eSDK installation time. There's only a warning about base-files do_install signature.


Just found answer for the above problem.
A previous commit changes poky.conf to make DISTRO_VERSION contain METADATA_REVISION.
"""
poky.conf: do not write current date into distro version, use git hash instead

"""

I also confirmed that merely updating the git revision will result in a rebuild of base-files.
Rebuild of base-files does not result in rebuild of other recipes because we have 'base-files' in SIGGEN_EXCLUDERECIPES_ABISAFE.

For the problem below, I haven't found the root cause, still working on it.

Best Regards,

In fact, this is a problem I found when I was dealing with another problem with eSDK.
Yocto's current eSDK cannot be successfully installed on a different distro. For example, you build esdk on ubunt18 and install the esdk on ubuntu20, then you'll get an error of pseudo do_fetch task re-run unexpectedly.
I think it might be related to NATIVELSBSTRING, but I haven't found out why.
Manually setting NATIVELSBSTRING to some fixed string such as 'Linux' will solve the above problem.

I'm still checking the codes. If you have some idea/suggestion, please let me know.

Best Regards,
