Use of multiple GIT repositories in SRCREV but updating PV

Use of multiple GIT repositories in SRCREV but updating PV

[Otavio Salvador]

Hello,

We have two recipes that use a common static library and every time we
change something on this library we need to bump PR of those recipes.
We want to avoid that specially for daily builds that will  be using
GIT AUTOREV support.

For it to work, we need to have a way to put two SRCREV in PV and then
it will be rebuit every time the library changes.

Any clue how to do that?

Set the PV as usual in the recipe:

PV = "0.0+gitr${SRCPV}"

and then set:

SRCREV = "${AUTOREV}"

?

He has multiple git repositories involved here, and wants to ensure it
gets rebuilt if either change.

As spoted by Chris we have multiple repositories and we want that
either change to raise a build of the recipe.

See linux-yocto as an example. You need to name the two git uris:

SRC_URI = "\
git://git.yoctoproject.org/linux-yocto-a;protocol=git;name=machine \
git://git.yoctoproject.org/linux-yocto-b;protocol=git;name=meta \
"

set a format string to determine how the revisions should be placed in
SRCPV:

SRCREV_FORMAT = "meta_machine"

specify PV:

PV = "0.0+gitr${SRCPV}"

and then something like:

SRCREV_meta = "${AUTOREV}"
SRCREV_machine = "${AUTOREV}"

Cheers,

Richard

I did it locally and it ...:

 - does the clones in DL_DIR file
 - gets the right SRCREV for both
 - gets the right SRCPV

However on unpack it fails; it always use S as '${WORKDIR}/git' even
if I change it in the recipe.

Something seems broken on bitbake support for it.

Clues?

Just to follow up for the benefit of the mailing list, we were missing a
patch Holger submitted a while back for this problem which has now
merged into bitbake master. You can now tell the fetcher to use
something other than "git" as the checkout directory.

Cheers,

Richard

Besides, on Meta-OE, I have put a newer version of  gitpkgv that
supports SRCREV_FORMAT as well.
