Set things up so that we can run abuild on the native chroot and use
it's cross compilation features rather than running it and the build
system through QEMU. This massively speeds up building when it works.
cross-native used to be quite limited in functionality and didn't
integrate into abuild itself, this commit fixes that.
Packages can opt-in to this by adding pmb:cross-native2 to their options
and configuring makedepends_host and makedepends_build.
This also speeds up building packages like postmarketos-initramfs since
it entirely avoids running commands through QEMU (usually abuild itself
would be run through QEMU).
Lastly, we preserve the old pmb:cross-kernel options, this can be used to
enable the old cross compiler behaviour which is used for cross
compiling kernels in pmaports. This allows them to keep being supporting
while we adapt them to the new cross-native2.

Replace aports -> pmaports in these messages.
$ pmbootstrap build systemd
[17:37:02] NOTE: The package 'systemd' exists in extra-repos/systemd, but systemd is currently disabled
[17:37:02] ERROR: Could not find package 'systemd' in pmaports
Some packages in aports have their own subpackages in their
dependencies, for some reason. This causes our resolver to assume there
is a cyclical dependency.
Adjust the resolver to safely ignore these dependencies, since they'll
be built as a part of the package that depends on them.
For example, modemmanager depends on libmm-glib which is a subpackage of
modemmanager. Currently to build modemmanager in pmaports it would be
necessary to manually modify the APKBUILD after copying it from aports.
This change avoids that.

It may be desirable to test older versions of packages, allow them to be

Here's the problem: Imagine a queue with 2 packages in it, the 1st
package uses crossdirect and the second uses cross-native. When building
the 1st package, pmb will configure the native chroot for crossdirect
as expected. When it gets to the 2nd package, the chroot env/config
might not be appropriate for actually doing a native cross compile.
This re-inits the cross compiler stuff if the cross compile method
changes while processing the queue.
Another approach that might solve this problem is to not re-use chroots
when building packages... I didn't think this was a good way to go
because it would greatly increase runtime (having to recreate chroots
multiple times)
When a dependency cannot be found in source or binary packages of the
selected architecture, then don't look for binary packages in other
architectures package indexes.
This leads to a confusing error down the line when building packages for
extra_repos_systemd (and e.g. stable branches), because we don't have
binary packages for all arches that pmbootstrap supports, and so it
tries to fetch a non-existing APKINDEX.
Instead, print a nice error about a non-existing dependency.
Adjust the dependency resolver, so it uses the main pkgnames in
dependency resolution, instead of subpackages. This fixes for example
that it couldn't find -dev packages even though the binary packages for
those existed.

Have messages like the following in "pmbootstrap log" to better
understand why resolving packages fails. The bug with -dev pkgs not
being recognized will be fixed in a follow-up patch.

Print a warning when breaking cyclical dependencies, for example with
current kde-nightly branch:

Set "stuck = False" in the "while disarray and not stuck" loop
directly, instead of setting it in the queue_item() function that gets
called from it. This way the loop logic can be understood without
looking at queue_item().
Most of the time when building it's reasonably safe to fall back on an
older binary package for building in order to break cyclical
dependencies (e.g. dbus and systemd depend on each other at build time,
but it's safe to build both against older versions of the other).
Implement the necessary logic to break cyclical dependencies by
detecting them and checking for the existence of a binary package.

Decide the order to build packages in by looking through the build queue
and making sure dependencies are queued before any packages that depend
on them, bailing out in the case of cyclical dependencies.
This should handle subpackages too.
Signed-off-by: Caleb Connolly <caleb@postmarketos.org>
When building with --src or --force, other logic to detect when to build
a package is skipped. However there are no (known) cases when someone
might want to build a package if the resulting binary package version
will be older than an existing binary package. Catch this case and fail
with recommendations for user action (update pmaports, clear local
binary repo).
This should help avoid the situation where you accidentally build an old
version of a package and it never actually gets installed.

build_packages like apk-tools and alpine-base might get picked up and
queued for build as dependencies of other packages. We don't want this
since we always ensure they are queued first. Avoid queuing them in this
case.

It turns out the current behaviour was not preserving the old behaviour
at all, and was wrong. We want to build ALL outdated or new packages we
encounter via the dependency graph.

We handle this correctly for dependencies of the base package but not
the base package itself.... Fix this.
Should avoid duplication here ideally.

A previous attempt inserted subpackage depends into the package depends
list returned by get_depends().
This meant that pmb would try to install subpackage depends when
building the package, which breaks for some cases like device packages
with kernel variants since the depends of different subpackages might
conflict with each other.
Let's instead just add the subpackage depends to the build queue, so
they get built like package depends, without being pulled in as build
dependencies for the package.

Bail on empty build queue after checking if build_packages need
building. So if apk-tools / alpine-base / etc are outdated but nothing
else is they'll still be built.

Now that we have target-version = "py310" in [tool.ruff] in
pyproject.toml, ruff check complains about using typing.Optional and
typing.Union instead of newer syntax. Run the tool to fix it.
In ("build: special case building abuild (MR 2356)") we tried to ensure
that abuild would be built before anything else, however this
implementation failed miserably if the first package given didn't
actually need to be built (since we skip building deps of packages that
aren't flagged for build).
Let's take a different stab at this by actually inserting build_packages
into the build queue if they need building. They're inserted at the end
just before the queue is reversed, so they will always be built first.
This makes the order of pmb.config.build_packages important, enshrine
this with a comment.

If you build a package with --src but some dep is outdated, force you
to build it (or otherwise handle the situation yourself). We can't guess
what to do here.
This could be made configurable (opt-in) in the future.

We might have just built some other package which will later be used to
build more packages. Handle all of them and don't special case abuild.
Signed-off-by: Caleb Connolly <caleb@postmarketos.org>
Since abuild is an implicit dependency of everything, we need special
case handling for it. Insert it as a dependency of the first package in
the build queue so that it will be built if outdated, then after
building re-install it in the chroot so all subsequent packages will use
the freshly built abuild.
This is currently used for systemd where we use an abuild fork
