2.6 migration guide

2.6 migration guide

[Paul Eggleton]

Hi folks

When Scott prepares the migration guide for a release, he usually looks to me 
to collate the notable changes for it (those requiring user intervention). I 
haven't prepared anything yet though and the 2.6 release is fast approaching. 
Can anyone who has been involved in or is aware of such changes in master for 
upcoming 2.6 (thud) make a note of it on the wiki in raw form on this page:

  https://wiki.yoctoproject.org/wiki/FutureMigrationGuide

Scott and I will take care of cleaning it up, so things added there don't need 
to be perfect. 

I will also be doing my usual trawl through the commits in the release for the 
more general changelog, so most things will get picked up that way, but it's 
really helpful if people with first-hand knowledge of the implications of some 
of these changes are involved in how they get documented.

Thanks,
Paul

Paul,

Thanks for sending.

Contributors....

I have an initial section at
https://yoctoproject.org/docs/2.6/ref-manual/ref-manual.html#moving-to-the-yocto-project-2.6-release,
which is based on Richard's input.  I am sure there are more items.

Thanks,
Scott

You might want to add a link to the bitbake manual or some example from 
there for the new functionality of _remove operator:

http://git.openembedded.org/bitbake/tree/doc/bitbake-user-manual/bitbake-user-manual-metadata.xml?id=c0a23dd9155c50a6b7df796980bc7b612cac7994#n334

FOO = "123 456 789 123456 123 456 123 456"
FOO_remove = "123"
FOO_remove = "456"

FOO is now: "  789 123456    " instead of "789 123456"

Can you tell me why "123456" is also not removed?  That string contains
instances of "123" and "456"

Because it removes all occurrences of the list value "123" and not of 
value "123456" or any part of it. Otherwise, it would be impossible to 
use this function to only remove, say, "1" from a long list of numbers. 
(here 'value' is not limited to a number).

In “4.14.2. OpenSSL Changes”, change “both versions their dependency chains” to “both versions in their dependency chains”.

OK, so I have removed Richard's items from the wiki page (since they're now
in the manual) and added items I have gathered from reviewing all of the 
git commits in the release. Let me know if you need clarification on anything
- everyone else, let us know if I missed or messed up something.

  https://wiki.yoctoproject.org/wiki/FutureMigrationGuide

BTW I think the section on postinstalls (from Richard's input) is a little terse
and needs expansion - most importantly it needs to describe what actions the
user might need to take. I'll take care of this on review if nobody else does.

Cheers,
Paul

I forgot one thing:

------- snip -------

Python 3 profile-guided optimisation
-----------------------------------------------

The python3 recipe now enables profile-guided optimisation; this requires a little extra build time in exchange for improved performance on the target at runtime, and is only enabled if the current MACHINE has support for user-mode emulation in QEMU (i.e. "qemu-usermode" is in MACHINE_FEATURES, which it is by default, so the machine configuration would need to have opted out for it not to be). If you wish to disable Python profile-guided optimisation regardless of the value of MACHINE_FEATURES, then ensure that PACKAGECONFIG for python3 does not contain "pgo". You could accomplish the latter using PACKAGECONFIG_pn-python3 = "pgo" at the configuration level or by setting PACKAGECONFIG using a bbappend for the python3 recipe.

So what I think we need here is to copy part of the "Using exit 1 to explicitly defer a postinstall script until first boot..." paragraph that's mentioned in the 2.5 migration section. Would it make sense to actually break this out to its own place in the documentation (on "Deferring postinstalls to first boot") and then link to that from both places?

While I think of it, could you also move the _remove item that's in the "Bitbake Changes" section into the "Override Changes" section?

Thanks,
Paul

Oops, I meant PACKAGECONFIG_remove_pn-python3 = "pgo" here.
