900522 - move RES_FILES to moz.build (java exports)

Status: RESOLVED FIXED

Comment 1

[Nick Alexander :nalexander [he/him]]

We want to do this as part of defining a build grammar for Java; see Bug 854530 and Bug 890534.

Attachment: Part 1: Make ANDROID_RESFILES a moz.build-only variable. r=gps

This depends on Bug 923306, which I think is close to r=glandium.
Since this is more moz.build than Android, r?=gps.

Attachment: Part 2: Use ANDROID_RESFILES in mobile/android/base/moz.build. r=gps

This defines ANDROID_RESFILES in mobile/android/base/moz.build but
does not use the default processing from java-build.mk.

Attachment: Part 3: Add passthru ANDROID_GENERATED_RESFILES. r=gps

This defines all of the Android resources in moz.build files (although
some are still generated by mobile/android/base/Makefile.in).

Man, I'm going insane.  This ticket does not depend on Bug 923306.

Comment 7

[Nick Alexander :nalexander [he/him]]

Heh, good thing I tried that.  Here's with the trivial fix.

I only glanced at the file lists. I trust things would break badly if you messed up.

There's no way I'm going to manually verify the list of files is consistent across the patch.

Did you diff the objdir or anything to verify output is consistent?

Please use a lowercase variable for local variables not used by rules.mk.

Can we not use INSTALL_TARGETS for these?

This is a very reluctant r+.

I would prefer we not move things to moz.build that still have their rules in individual Makefile.in files (only rules.mk). However, I know you are trying to enable IDE project generation for Fennec. That goal warrants bending the rules a bit.

I've built with this many times, and verified all sorts of things by hand.  I'm not worried about busting the lists, since un-busting is trivial.

This is sneaky -- it is a variable used in rules.mk (well, java-build.mk), so this patch sets it, but then adds another variable to ignore it in rules.mk.  Let me post the follow-up which makes this less insane.

INSTALL_TARGETS doesn't handle nested directories, so we'd need 20 targets.  The follow-up will explain why I didn't do that.

I hear that.  I have a follow-up that installs the ANDROID_RESFILES using manifests, which is why I didn't go the final mile and build rules.mk support for mobile/android/base's resources.  (It's hard to do in make!)

config/makefiles/java-build.mk says it's export, not libs.
