Normally toolchains packages are prevented from upgrading. This
drops that restriction and explicitly removes old versions so that
conflicting tool profiles are not accidentally used.
This reverts commit 20975049b3.
This omits the toolchain packages' version-pinning flag for the
binutils package while it is being upgraded. It also removes older
versions installed in parallel that cause unwanted rebuilds.
When stable has the upgraded version, this can be reverted.
This seems to fix the ccache permission issues `update_chroot` hits
while building ninja.
The erroneous files were created as root:portage, so a umask of 002
should let other portage group members share them, which seems entirely
reasonable.
Instead of patching portage to support the `disabled` flag now we just
patch it to leave the `[gentoo]` section out of the default repos.conf.

This variable was semi-deprecated ages ago so `version.txt` could follow
a similar variable naming pattern to `os-release`. Finally drop usage of
it here in favor of `$COREOS_VERSION`.
When --usepkgonly is mixed with the right update flags it will
re-install any binary packages that have a newer build. Since the full
set of SDK and board packages are rebuilt quite often this leads to
excessive reinstalling.
Before attempting to do @preserved-rebuild to fix linked against old
libraries remove any packages that no longer have corresponding ebuilds,
making them impossible to rebuild. This uses `--depclean`'s secondary
meaning: `--unmerge` but only remove packages without dependencies.
Rebuilds packages that are linked against old libraries that have been
upgraded or removed from the system. Skipping this can lead to shared
library checks looking ok in the build root but then built images have
broken library dependencies.
The distfiles cache is always under .cache in the repo tree but there is
a lot of extra logic to make that configurable along with compatibility
symlinks for previous locations. Just yank it all out.
A step in reducing the amount of initialization code required: drop
needless symlinks under /usr/local/portage to the portage trees. Just
configure portage to point directly at the source instead. Only crossdev
remains in that location because it is a locally managed overlay.
This is required for the eventual removal of `$PORTDIR` and
`$PORTDIR_OVERLAY` and ensures toolchain rebuilds/updates with
`./build_packages --nousepkg` don't erroniously try to use ebuilds from
`/usr/portage` inside of the SDK.
In order to fix up the build_toolchains script the crossdev overlay
needs to be setup properly, previously only setup_board did it.
Overall silences a lot of warnings and fixes an issue with crossdev:
/usr/bin/emerge-wrapper: line 48: /eclass/toolchain-funcs.eclass: No such file or directory
/usr/bin/emerge-wrapper: line 49: tc-arch: command not found
Normally Gentoo expects moving between major GCC releases to be a manual
step. In our case we want this to always be automatic, otherwise the GCC
version won't be switched at all.
Using parallel_emerge has been disabled by default for all commands
except build_image for quite a while now, build_image kept it just
because it was still a bit faster than normal emerge. Keeping
parallel_emerge complicates future changes to build_image so it needs to
drop it entirely. Since that means nothing uses it by default we might
as well just rip out support for it entirely.
To behave more like setup_board/build_packages update_chroot should
fully configure portage to make sure everything is accurate.
Now binhosts are defined in make.conf.host_setup so the static config in
coreos-overlays doesn't need to refer to version.txt. setup_board
already made this change in 7a43a07f.
Define path locations to reduce dependency between static configs in
coreos-overlays and the behavior of the scripts repo. Spreading
configuration across two repos makes everything harder to understand.
Eventually everything should either be defined in profiles in
coreos-overlays or minimal auto-generated config files here in scripts.
The latest release of portage uses repos.conf, so generate that
file when making the chroot. The crossdev overlay also needed
repo_name and layout.conf files.
- Remove custom COREOS_* attributes from /etc/lsb-release
- Move dev image logic to dev_image_util
For extra fun fix detection of local host URL for devserver.
- Remove weirdly verbose "DESCRIPTION" format.
- Add COREOS_RELEASE_BOARD back to /usr/share/coreos/release
This is mostly just so update_engine and gmerge report the correct
board name to devserver, informative-only on prod images.
- Remove version info from /etc/gentoo-release
- Switch from 'track' to 'group' terminology.
I would like to phase out parallel_emerge so disable it for all commands
other than build_image which is the only one that shows a noticeable
benefit from it (~2 min with --fast, ~3 min with --nofast).
Soon nss-usrfiles will be required to resolve users and groups properly.
To avoid potentially breaking during the transition we need to make sure
the package is installed early during the chroot upgrade process.
This makes it possible to toggle parallel_emerge just as other scripts
do. In other scripts update the help string to be more specific, the
--jobs option can be used to control parallelism.
This doesn't currently have any real impact but seems like a better
ordering since update scripts may need to emerge things.
Add some friendly version info logging.
The old chroot version system we inherited from Chromium OS always
assumes that a newly unpacked tarball is the latest and greatest but
since we version the SDK in the same way as target builds we can use
that version for these sorts of upgrade scripts and not make assumptions
about how late and great the starting tarball was.
The first upgrade script simply aborts to force the user to recreate
their chroot when moving from python 2.6 to 2.7.
