I'm more a Software architect. Sometimes it's hard to explain what you should do in the enterprise. I work on improve this state of thing.

OpenEmbedded Experience

2006 - 2007 : Paper-book project

Prototype for paper-book

• http://scourge.fr/mathdesc/images/pb/PB-2.JPG
• http://scourge.fr/mathdesc/images/pb/PB-3.JPG

2007 - 2008 : Nao

Soon some information about it.

Wishlist

This section is my wiki for idea i'd like to work to improve my openembedded Some are perhaps really bad ideas ( not enough searsh ), or already exists , let me know.

better logs reports

i missed important error compiling lost of software

• http://opensource.bolloretelecom.eu/projects/oestats/wiki/oestats
• should we use logging python module ?

bugzilla integration

if ( OE_WARN_BUG == 1 )
 checkbug(${PN})

bitbake -bugz mozilla 

cf :

• seppuku.bbclass
• http://code.google.com/p/pybugz/source/browse/trunk/README?r=28

reduce image size method

Reduce image size using remote lsof session on target to check useless files , packages ( blame useless dependency ) ... diff with $ROOTFS and eventually try them by size.

#REMOTE_METHODE = "ssh 192.168.0.1"
REMOTE_METHODE = "tty /dev/USBtty1"
bitbake -lsof-session mycustom-image.bb

http://www.ibm.com/developerworks/linux/library/l-inotify.html

i should also try some code inspector ( to check code duplication etc to advise programmer where place could be saved ). Some Steiner stuff on fusil could be useful.

• /usr/include , /usr/share/, /usr/src ... .debug directory should be tested first.

report tool

print beautiful documentation on the distro/packages/whatever.

• template design
• baobab ...

perharps reportlab APPS for oestats. Look http://docs.djangoproject.com/en/dev/howto/outputting-pdf/ ( example works pretty well).

netboot images

mkelf-linux kernel-image [ramdiskimage] keywords : initramdisk

some QA ideas

fuzzing our softwares

opkg, bitbake etc

• using fusil ( fuzzing report ) ,

i made the recipe see bug 4495 look success story at http://fusil.hachoir.org/trac/wiki/CrashList

more documentation

bitbake documentation

I started bitbake developer documentation here : Bitbake TODO :

• provide documentations about how to make better code in bitbake
• pydoc , doctest , unittest , pyunit , pylint...
• byte compiling bbclass , what is done by cache ?
• http://lists.idyll.org/listinfo/testing-in-python
• categories for /classes : qa,pkg,build,doc,...

bbclass documentation

• should this features be implemented as a bbclass or in bitbake core library ?
• authors and contact in bbclass ! some of its need to be rewrite due to changes in python => 2.4 , we should detects them

and add to a TODO-featuring tracker.

• force to provide documentation as a policy

test quality of a recipe

• (all ?) field well filled
• SRC_URI tarball contains no P/PV/PN => dangerous
• no SRCREV fixed , PV = "x.y.z+svnr${SRCREV}" :

perharps allow in a pending branch and auto-apply in the stable one. http://projects.linuxtogo.org/pipermail/openembedded-devel/2007-July/002639.html

• are SRC_URI fetchable ? we can fix it automagically changing SRC_URI for our MIRROR
• initscript without INITSCRIPT mecanism ( we need , for each new mecanism, write a recipe test and documentation )
• do_install with cp cmd instead of install
• warns on RPROVIDES
• recipe modification without upgrade the PR

cf : http://handhelds.org/~zecke/bitbake-qa-0.1.tar.bz2

OpenEmbedded showcase

We should promote OE projects (not only fic & o-hand.com stuffs)

target web interface

• port Webif to OE

my bug report on this : WIP

• libopkg client support ( via http://packagekit.org/ ? )
• start a new one from scratch ? ( pylons based for example ).

delivery/release class

Produce a report on a delivery. Tool that give good report are often appreciated ( there is something to show ). Managers/customers/developers can keep useful and pretty traces of their projects.

• log/tag revision of each versioned tree ( that are not in distro/src-revs ) ( mtn status / svn info / -> rev-history , delivery-info )
• show software update
• show infos on bugs ( closed/news etc ) as a changelog
• show stats about image and packets ( boabab etc )
• show copyrights , licenses ...

emulator/qemu tasks

some tasks that could be used for tests and debug.

• image is bootable ? ( ca be call in testsuite of task that build the img )
• test first boot
• upgrade not failed ? ( print the guilty )
• broken linkage ? ( can be call in testsuite of sanity.bbclass )

provides some methods

• build image
• launch with adapted parameter according to a qemu-machine conf
• NFS etc

see poky anjuta plugin and poky qemu scripts.

coreboot integration

• some recipes for utils
• use openembedded instead of buildrom ( yes another build system :/ )

Gentoo ebuild compatibility

using script ( crazy ) or common variables ( completely crazy ).

use git facilities

locate bug when upgrading oe

something like :

git bisect start
git bisect bad
ops = rec_ops(BB_CMD)
if [ $? -eq 0 ]
 git bisect bad
 undo_ops(ops)
else 
 git bisect good
fi

• if bug is a non-version fixed package , fix version and continue
• make a report
• cf http://www.miximum.fr/methodes-et-outils/79-debusquer-une-regression-avec-git-bisect ( fr )
