[gentoo-dev] DEVS: depedency checking for other arches

Hi all,

Just a request/plea to developers in regards to adding/adjusting 
dependencies on ebuilds that have multiple arch keywords (i.e. x86, ppc, 
sparc, mips, etc).  When a dependency is added or adjusted for an existing 
ebuild, particularly ones that have multiple arch keywords, please please 
please check to see if those dependencies can be built for all other 
arches for the same tree the ebuild you are working on is currently marked 
for (stable or unstable).

An example of what sometimes happens;

I'm working on ebuild foo-1.0.ebuild.  A bug comes in asking to fix a 
dependency on foo-1.0.ebuild so that it will depend on bar-1.0.  
Currently, foo-1.0.ebuild has keywords for x86, ppc and ~sparc.  However, 
bar-1.0.ebuild only has keywords for x86.  A dev who only has x86 to test 
on adds the dependency to bar-1.0 into foo-1.0.ebuild and closes out the 
bug.  Unknowingly to that dev, he's just caused a dependency break for ppc 
and ~sparc because repoman isn't checking for these, only x86.


I have submitted a bug for repoman to get the capability to check 
dependencies for arches other than the one you are currently on (#24160).

In the meantime, a couple suggestions as to how to handle this;

1) When adjusting ebuilds, check to see if the dependencies have the same 
keywords.   If not contact a dev from that arch to see if they can test 
those packages and get them marked similarly to the ebuild you are working 
on.

2) Make the new/adjusted dependencies only for the arches you can test on, 
and then create bugs in bugzilla asking the other arches to test the 
dependencies.


Thanks, and reply away! :-P
