This is a brief guide to describe the necessary steps to update a port from an overlay repository.
The right order to maintain overlays is: core-arm, opt-arm, xorg-arm, <officially-supported_device>-arm, <officially-supported_device>-arm, ...
This means that we should not start with a port from opt-arm if there is a pending update port from core-arm.
Get a copy of devtools.git and use checkOverlayUpdates.sh to look for new available updates upstream:
$ checkOverlayUpdates.sh core-arm Results for overlay: core-arm PORT VERSION UPSTREAM util-linux 2.24-1 2.24.1-1 (core)
Note that you must run 'ports -u' before use checkOverlayUpdates.sh to be sure you are up-to-date
If there are available updates we must to know the differences applied upstream.
For this case we should go to CRUX upstream's gitweb interface:
If upstream changes are trivial as increment the version number, then apply the same difference to the Pkgfile and build the port:
However, if something must be adapted to ARM devices then it will need more work.
At the end, if we can't update the port overlay then we should file a ticket with all the research progress we made.
The ticket must be tagged as task type: Update Request, and it should contain a brief description of the problem, and all the needed info to reproduce it. Also it would be fine to append all the research info, useful url links, etc.
