Sveretenov:

I'm more a [http://en.wikipedia.org/wiki/Software_architect 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 [http://www.paper-book.com paper-book]

* http://scourge.fr/mathdesc/images/pb/PB-1.JPG
* 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 [http://www.reportlab.org/rl_toolkit.html 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 [http://fusil.hachoir.org fusil] ( fuzzing report ) ,
i made the recipe see [http://bugs.openembedded.net/show_bug.cgi?id=4495 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

== common & easy script encapsulation ==

== 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 )

== IDE integration ==
