sstate.bbclass: Ensure machine specific stamps are only wiped for the current task

sstate.bbclass: Ensure machine specific stamps are only wiped for the current task

[Richard Purdie]

sstate was being a little too ethusiastic about removing stamp files and
was removing stamp files for other machines when it shouldn't have been.

This patch teaches sstate about machine specific stamp extensions and
allows it to only remove the current task's stampfiles.

Based on a patch from Phil Blundell <philb@gnu.org> with some tweaks
from me.

Not sure if it's related to this problem or not but sstate is still not working as intented for me when switching machines, it keeps rebuilding the toolchain when switching machine. What I did this morning:

1) wipe out tmp, sstate-cache, pseudodone
2) MACHINE=beagleboard bitbake u-boot
3) cp conf/machine/beagleboard.conf conf/machine/brokensstate.conf
4) MACHINE=brokensstate bitbake u-boot

What I suspect is happing is that angstrom is somehow putting $MACHINE in a var that upsets the sstate logic and/or rm_work upsets sstate and/or something else is broken. The problem is that I have no idea how to debug this except to ping Richard and get the magic diffsigs incantation.

Koen

DISTRO=shr

MACHINE=nokia900 bitbake shr-image -> builds from scratch, finished ok
MACHINE=palmpre bitbake shr-image -> builds from scratch, finished ok
MACHINE=palmpre2 bitbake shr-image -> builds from scratch, finished ok

without wiping anything (same tmp, same sstate-cache, same pseudodone)

MACHINE=palmpre bitbake shr-image -> builds from scratch, again!, finished ok
MACHINE=palmpre2 bitbake shr-image -> builds from scratch, again!, finished ok
MACHINE=nokia900 bitbake shr-image -> builds from scratch, again!, finished ok

palmpre and palmpre2 are "the same"
$ cat meta-smartphone/meta-palm/conf/machine/palmpre.conf | grep -v ^#
require conf/machine/include/palmpre.inc

$ cat meta-smartphone/meta-palm/conf/machine/palmpre2.conf | grep -v ^#
require conf/machine/include/palmpre.inc

nokia900 is also armv7a-vfp-neon (that's why all packages except
MACHINE_ARCH were always reused without rebuilding in OE-classic).

I have tried to debug sigdata files to see why and also tried to add
MACHINEOVERRIDES[vardepsexclude] = "MACHINE"
as RP suggested, but sofar haven't found solution at least to reuse
already built sstate packages for armv7a-vfp-neon.

Also as a tip for debugging this, you can do what is in the following
commit (patch also inline below):

http://git.yoctoproject.org/cgit.cgi/poky-contrib/commit/?h=rpurdie/wip9&id=1261cc69b152f33b934c2448020dfa3c95f312c6

which will mean bitbake -n generates stamp files for a given bitbake
run. You can then quickly do:

MACHINE=A bitbake -n foo
MACHINE=B bitbake -n foo

for example and then look for cases where two stamp sigdata files were
generated. If you see them you can "bitbake-diffsigs A B" and I'll be
very interested in the results of that and "bitbake-diffsigs A"...

Cheers,

Richard

I've posted a patch which at least locally solves the issue with the "cp
MACHINEA MACHINEB". If there are more issues I'd be interested, see my
separate email with some debugging tips.

These are deliberate and don't make sense in poky.

These are related and I need to get this fixed, there is an open bug
about this.

Not showing up here for me...

> Files poky/bitbake/lib/bb/parse/parse_py/BBHandler.py and bitbake/lib/bb/parse/parse_py/BBHandler.py differ

This is whitespace only.

This is a generated file and in neither repository.

This is a reminder that we'd like a bitbake shell to come back.

>Files poky/bitbake/lib/bb/runqueue.py and bitbake/lib/bb/runqueue.py differ
>Files poky/bitbake/lib/bb/build.py and bitbake/lib/bb/build.py differ

and these are the main "problem". Some is related to the bitbake-runtask
piece above, there were also a couple of patches I didn't like to
bitbake and didn't take into poky.

There isn't anything particularly major here, just reminders of areas
that could do with some dedicated cleanup or rethinking. Bitbake master
takes the short cut of skipping tasks during dry run without forking. My
patch assumes that the fork is made to generate the stamps. An updated
patch is below.

Cheers,

Richard

Hi,

to recap what we have talked about on ELCE;

Currently it doesn't seem to change sstate checksums after switching
MACHINE, but still it rebuilds everything at least once after switch.

Today I've tried to wipe tmp and rebuild from sstate-cache and I've
noticed interesting thing:

All recipes are starting with 
do_populate_lic_setscene 
not 
do_populate_sysroot_setscene
like ie koen's build does

NOTE: Resolving any missing task queue dependencies
NOTE: Preparing runqueue
NOTE: Executing SetScene Tasks
NOTE: package quilt-native-0.48-r0: task do_populate_lic_setscene: Started
NOTE: package shr-image-2.0-r18: task do_populate_lic_setscene: Started
NOTE: package quilt-native-0.48-r0: task do_populate_lic_setscene: Succeeded
NOTE: package shr-image-2.0-r18: task do_populate_lic_setscene: Succeeded

Does do_populate_lic_setscene wipe all stamps after do_populate_lic so it 
causes the rebuild instead of population of sysroot from sstate?

IIRC I had similar issue when I was starting to use oe-core and it was 
in the end caused by inheriting package_ipk (once directly from distro config 
and once through sane-feed-ipk.inc) and it was fixed 6 months ago by:
http://git.shr-project.org/git/?p=meta-shr.git;a=commit;h=00623b3c6dd01c4a227008f7cfdb0801cb06f49a
And IIRC we've talked about some ways to make sstate less error-prone
for such things.

Now I have similar symptoms but only after switching MACHINE.

Any hint?

With few more hours of debuging this.. I can say that sometimes it works, 
but sometimes it's too strict to be usefull anyway.

Whole logs are here:
http://build.shr-project.org/tests/jama/sstate.test
here I'll try to shorten as much as possible.

So it seems we have the same populate-lic.tgz.siginfo for all 3 machines but remaining tasks are 1 for each machine.

so lets check deploy-ipk for qemuarm and qemuarmcopy..

ahh lots of changes.. but wait!
So MACHINE=qemuarm first said
NOTE: Tasks Summary: Attempted 2428 tasks of which 2427 didn't need to be rerun and 0 failed.
but sstate checksums were invalid already for qemuarm (ie due to OPKGBUILDCMD change)

So let's retry with clean sstate:

ls: cannot access sstate-expat-armv5te-oe-linux-gnueabi-2.0.1-r1-armv5te-2-*: No such file or directory

OK no sstate tgz for all 3 armv5t machines

libproxy was built because I had to cleansstate it in first qemuarmcopy build - remember?
gobject-introspection-native was rebuilt for some reason, but probably not important

but why did it build expat again?

aaah so they're compatible only as far as they have completely the same TUNE_CCARGS?

few more white-spaces to see the diff:

That's pity as they are overwritting the same files in feeds:

OE qemuarm@shr ~/shr-core $ ls -lah tmp/deploy/ipk/armv5te/libexpat*

So user won't know if the package he downloads was built as qemuarm or qemuarmcopy or spitz..
all he will notice is that md5 sums for ipk files are changing alot.

This is also related to older thread about sstate
http://lists.linuxtogo.org/pipermail/openembedded-core/2011-May/003308.html

I'm going to try
BB_SIGNATURE_HANDLER = "basichash"
as it's supposed to become default anyway IIRC.
