Well, do we want it in the package set? I figured we were talking about "informal" builds that might be put up for ftp, but not be an integrated part of the Fedora world. If one rpmbuild from the spec kicks out -vanilla packages along with other variants, and we turn that on only for rawhide, still it winds up "in the system", people install it as "normal" and wind up with upgrade issues and all that. Eventually we have clueless Fedora users saying "you use -PAE? well -vanilla is the Fedora kernel I like best!" and reporting in bugs "why this fix isn't in -vanilla too?" It's easy to tweak my changes to put "vanilla" into %name instead of %release. I went with "kernel" and a long, funky %release because that's the tradition I've experienced for one-off and test builds people distribute. From my own experience juggling a dozen installations on two or three test boxes with many hack kernels installed each in an utterly disorganized fashion, it seems more likely to get resolved usefully when doing upgrades and such than an rpm named "kernel-foobar". That is, yum and rpm will get in your face all the time in the way that people are used to for juggling kernel rpms. (Also, I always shudder in superstitious fear that yum or who knows what will assume things about the kernel rpm being the way it always has been.) With whatever name, separate vanilla builds could easily be made usable as their own little yum repository. What is more work, and I think is more dubious, is having it be the same srpm that produces both fedora and vanilla builds. What will -bp do, make two source trees patched differently? That's no fun! Seriously, I think we need the full suite of variants (modulo xen until that's uptsream, etc.) for it really to be useful. Plenty of people are using -PAE and the point is to compare the foo you're using to foo-vanilla on a one-to-one basis, i.e. different source, same .config settings. And you want -debuginfo for all of those too. I despise how much duplication there is in there. The debuginfo stuff I originally did with rpm macros got hand-expanded because older rpmbuild couldn't cope with it. Maybe nowadays there is nothing with an rpmbuild older than FC-5 we are trying to work with, so we could use more macros for new stuff. (I think brew got fixed to use the buildroot's rpmbuild, so anything that's fine for the target systems sharing the kernel spec source should be fine.) rpm macros are a hairy mess, but cleaning things up with clean new macros is a better bet than anything else, IMHO. Here's the current version of it. You still need the nonintconfig patch variant I posted last time to go with this. I also attached below the shell script used by the GIT-using hacks that are in this version. http://porkchop.devel.redhat.com/brewroot/scratch/roland/task_703101/ shows what "make git/roland/scratch-build" does (the build magic works for "make git/roland-fedora/..." too, but the fedora patches don't apply to current upstream so it didn't build). This (the non-fedora flavor) is similar to the vanilla build, but automagically prepends: %changelog * Thu Mar 29 2007 Roland McGrath <roland(a)redhat.com&gt; - Experimental build from git sources (no Fedora patches) - git tag: v2.6.21-rc5 6fb04ccf5c5e054c4107090bed6e866489f1089f - git branch: upstream 28defbea64622f69d65a6079bf800cedb9915a5f - git branch: roland 0ca00c859e7ac4d9d053abd06376233cb4f3bf84 and includes: Patch1: patch-2.6.21-rc5.bz2 Patch2: linux-2.6.21-rc5-upstream.patch Patch3: linux-2.6.21-rc5-roland.patch Thanks, Roland Index: Makefile =================================================================== RCS file: /cvs/dist/rpms/kernel/devel/Makefile,v retrieving revision 1.45 diff -u -B -p -r1.45 Makefile --- Makefile 19 Mar 2007 21:32:30 -0000 1.45 +++ Makefile 30 Mar 2007 21:45:57 -0000 @@ -68,3 +68,119 @@ reconfig: # since i386 isn't a target... compile compile-short: DIST_DEFINES += --target $(shell uname -m) + +# +# Hacks for building vanilla (unpatched) kernel rpms. +# Use "make vanilla-TARGET" like "make TARGET" (make vanilla-scratch-build). +# +vanilla-%: $(SPECFILE:.spec=-vanilla.spec) + @$(MAKE) $* SPECFILE=$< + +$(SPECFILE:.spec=-vanilla.spec): $(SPECFILE) + @rm -f $@ + (echo %define nopatches 1; cat $<) > $@ + +scratch-build: test-srpm + $(BUILD_CLIENT) $(BUILD_FLAGS) --scratch $(COLLECTION) \ + $(SRCRPMDIR)/$(NAME)-$(VERSION)-$(RELEASE).src.rpm + +# Dismal kludge for building via brew from cvs after "make vanilla-tag". +ifdef BEEHIVE_SRPM_BUILD +export CHECKOUT_TAG ?= $(shell sed s/^.// CVS/Tag) +tag-pattern = $(TAG_NAME)-$(TAG_VERSION)-0_%_$(TAG_RELEASE) +ifeq (,$(filter-out $(tag-pattern),$(CHECKOUT_TAG))) +variant := $(patsubst $(tag-pattern),%,$(CHECKOUT_TAG)) +srpm: SPECFILE := $(wildcard $(SPECFILE:.spec=-$(variant).spec) \ + $(SPECFILE:.spec=-t.$(variant).spec)) +srpm beehive-sprm: RELEASE := 0.$(variant).$(RELEASE) +endif +endif + + +# +# Hacks for building kernel rpms from upstream code plus local GIT branches. +# Use "make git/BRANCH/TARGET" like "make TARGET". +# Use "make git/BRANCH-fedora/TARGET" to include Fedora patches on top. +# +ifndef GIT_SPEC +git/%: + @$(MAKE) GIT_SPEC=$(subst /,-,$(*D)) git-$(*F) +else +git-%: $(SPECFILE:.spec=-t.$(GIT_SPEC).spec) + @$(MAKE) GIT_SPEC= $* SPECFILE=$< +endif + +# +# Your git-branches.mk file can define GIT_DIR, e.g.: +# GIT_DIR = ${HOME}/kernel/.git +# Make sure GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL are also set +# or your rpm changelogs will look like crap. +# +# For each branch it can define a variable branch-BRANCH or tag-BRANCH +# giving the parent of BRANCH to diff against in a separate patch.
