Currently, base-apt is used in the following way:
* At first build every deb file that took part in installing is cached
in directory $DL_DIR/deb/. Debootstrap is done from remote source.
* At second build, `base-apt` repo is created from previously downloaded
debs (if ISAR_USE_CACHED_BASE_REPO is set). Debootstrap and installing
packages later is done from this local repo
The idea of this patchset is to precreate `base-apt` at first build and
use it later for all steps that require any package downloads (build
dependencies. rootfs populate, etc). So, no second build is required
to get ready-to-use base-apt.
Currently, only native builds are supported. Architecture related
dependencies predownloading is not yet ready, so cross-builds are not
working at the moment.
In the future, there are plans to switch from debootstrap to mmdebstrap
that is able to work without sudo and uses more clean (apt/python-apt)
approach in comparison with debootstrap.
Changes since v2:
- populate base-apt before using at all steps of native build.
Changes since v1:
- rebased on latest next;
- updated patchset description.
Uladzimir Bely (5):
Add debrepo python script handling base-apt
meta: Use cached base-apt repo to debootstrap
meta: always use base-apt repo in local mode
base-apt: Predownload packages to base-apt before install.
draft: make isar-apt repo visible for base-apt

This patch makes local base-apt repo to be created before
debootstrap task. So, debootstrap is then done from it.
The required packages are downloaded via python-apt and
reprepro creates debian-like repository from .deb files.
For debian targets host keyring is used while ubuntu/raspbian
targets use keys specified by DISTRO_BOOTSTRAP_KEYS variable.
The goal is have workable base-apt repo before first build completed.

This means that only local URLs in apt sources.list* is present during
the build. Any installation of packages is done from local base-apt.
So, base-apt should be always mounted in *_do_mounts since now.

some packages in isar-apt (like sshd-regen-keys) may depend on debian
packages (openssh-server). So, base-apt need access to isar-apt repo
to be able to download these deps.

Hi,
This looks like a lot of code duplication.
We already have a bunch of similar calls to apt spread across ISAR.
Just to name a few:
- buildchroot/files/deps.sh
- deb-dl-dir.bbclass
- dpkg-base.bbclass
- dpkg-gbp.bbclass
- image-locales-extension.bbclass
- image-tools-extension.bbclass
- rootfs.bbclass
- isar-bootstrap.inc
With sbuilder the situation will get even worse, as the do_install_builddeps task is no longer available.
By that, users that have to prepare their sources in advance to building will manually have to fiddle around with apt to install pre-build dependencies.
Affected OSS layers I know of are meta-coral (dpkg-bazel.bbclass) and meta-iot2050 (npm.bbclass).
Maybe we should re-think our apt handling and add a proper infrastructure.
By that, we can handle all options centrally and give the user an easy to use interface to install a package.
Also error prone aspects like mounts and locks should be handled by that infrastructure.
Finally, this would significantly reduce future maintenance effort in downstream layers.
Felix
