Allow setting _custom mirrors in the config:
* alpine_custom
* pmaports_custom
* systemd_custom
When these are set, they are added to /etc/apk/repositories before real
repositories. This is used by bpo to build packages with a WIP
repository enabled, in addition to the final repository.
All mirrors can also be set to "none" to be disabled. This is important
for bootstrapping from pure Alpine without any binary repository, and
the bpo testsuite also uses this.
I've discussed with Caleb whether to name it _wip instead of _custom,
but the latter is more generic and people may also use this for other
use cases than the bpo wip repository thing.
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.
Python 3.10.12 fails without this patch:

It turns out that apk with the --root argument will still treat local
repositories relative to the host. This makes sense considering the
intended usecase, however as a result the recent change to use
apk.static for all apk commands inside the target root will break the
use of local packages.
To fix this, adjust how we populate /etc/apk/repositories, changing the
default to no longer include the local user repo. Instead we pass
--repository to apk.static with the host path to the repo.
The only time we want to add the user repo to /etc/apk/repositories
inside the chroot is when the user enters the chroot, so a special case
is added to helpers/frontend.py for the chroot command.

Generalise pmb.helpers.other.cache with a more python decorator.
The Cache decorator takes a list of function arguments to use as cache
keys, keyword args can be used to restrict caching so that it is skipped
entirely unless the attribute has a specific value.
For example, pmb.helpers.pmaports.get() has the decorator:
@Cache("pkgname", subpackages=True)
This means the return value will be cached only when subpackages is
True, otherwise it will always miss.

Use the new config.mirrors section to handle repository URLs instead of
the old mirror_alpine / mirrors_postmarketos options. This let's us
add the systemd staging repo automatically when on the systemd staging
branch / systemd is enabled.

Move pmb/parse/arch.py over to core and refactor it as an Arch type,
similar to how Chroot was done. Fix all the uses (that I can find) of
arch in the codebase that need adjusting.
The new Arch type is an Enum, making it clear what architectures can be
represented and making it much easier to reason about. Since we support
~5 (kinda) different representations of an Architecture (Alpine, Kernel,
target triple, platform, and QEMU), we now formalise that the Alpine
format is what we represent internally, with methods to convert to any
of the others as-needed.

Cease merging pmbootstrap.cfg into args, implement a Context type to let
us pull globals out of thin air (as an intermediate workaround) and rip
args out of a lot of the codebase.
This is just a first pass, after this we can split all the state that
leaked over into Context into types with narrower scopes (like a
BuildContext(), etc).

Testing by building postmarketos-initramfs (which installs >100 packages
but is very fast to build, so a worst-case scenario) this results in a
~15-20% speedup (which everything cached and doing multiple back to back
runs). From 32 seconds down to 25.
Doing a full install with --no-image, this takes us from 70 seconds on
my laptop down to 40s!
This also lets us drastically simplify pmb/helpers/apk.py!

With the new chroot type, we can now write fancy paths in the pythonic
way. Convert most of the codebase over, as well as adding various other
type hints.

We use a custom verbose log level in pmbootstrap, unfortunately it isn't
possible to correctly type this due to some limitations in the logging
library [1], [2].
Given that our usecase is fairly simple, we can just wrap the module
with our own so we only have to tell mypy to ignore the error once
instead of at every callsite.

Introduce a new module: pmb.core to contain explicitly typed pmbootstrap
API. The first component being Suffix and SuffixType. This explicitly
defines what suffixes are possible, future changes should aim to further
constrain this API (e.g. by validating against available device
codenames or architectures for buildroot suffixes).
Additionally, migrate the entire codebase over to using pathlib.Path.
This is a relatively new part of the Python standard library that uses a
more object oriented model for path handling. It also uses strong type
hinting and has other features that make it much cleaner and easier to
work with than pure f-strings. The Chroot class overloads the "/"
operator the same way the Path object does, allowing one to write paths
relative to a given chroot as:
builddir = chroot / "home/pmos/build"
The Chroot class also has a string representation ("native", or
"rootfs_valve-jupiter"), and a .path property for directly accessing the
absolute path (as a Path object).
The general idea here is to encapsulate common patterns into type hinted
code, and gradually reduce the amount of assumptions made around the
codebase so that future changes are easier to implement.
As the chroot suffixes are now part of the Chroot class, we also
implement validation for them, this encodes the rules on suffix naming
and will cause a runtime exception if a suffix doesn't follow the rules.
Replace "args.cache" with a global variable in order to
avoid passing "args" to all functions. This is a step to get rid of this
args-passed-to-all-functions pattern in pmbootstrap.
Replace "args.arch_native" with the direct function call in order to
avoid passing "args" to all functions. This is a step to get rid of this
args-passed-to-all-functions pattern in pmbootstrap.
Hide progress bars if --details-to-stdout is used, which redirects all
output that would land in the pmbootstrap log to stdout. This caused the
progress bar output to get mixed with the apk output. A new progress bar
would get drawn whenever a new package was installed, without removing
the previous progress bar.
Migrate to workdir version 5 and move already built packages into the edge
channel subdir, for example:
$WORK/packages/x86_64/hello-world-1-r5.apk
to:
$WORK/packages/edge/x86_64/hello-world-1-r5.apk
The build.postmarketos.org code has already been adjusted to find built
packages in either directory structure.
Replace the call to this function with the almost identical
pmb.helpers.repo.apkindex_files(), so release channel related changes
only need to be done in one place.
Use mirrordir_pmos and mirrordir_alpine from channels.cfg to generate
the mirror URLs for postmarketOS and Alpine, which get written to
/etc/apk/repositories and which postmarketOS uses to download the
APKINDEX files.
Remove hardcoded "master" at the end of the postmarketOS mirror and use
mirrordir_pmos instead (which is "master" for the edge channel). Let the
postmarketOS mirror end in a '/' for consistency with the Alpine mirror
in pmb/config/__init__.py.
Remove obsolete --alpine-version. To experiment with a different Alpine
version, one should pass a custom --config-channels from now on.
Don't generate the postmarketOS mirror URLs here, let the urls()
function do it. A follow-up commit will touch this code, hence it's
important to have it de-duplicated.
While at it, also remove unnecessary "#!/usr/bin/env python3" in files
that only get imported, and adjust other empty/comment lines in the
beginnings of the files for consistency.
This makes files easier to read, and makes the pmbootstrap codebase more
consistent with the build.postmarketos.org codebase.
In pmb.helpers.repo.alpine_apkindex_path(), default to
arch = args.arch_native *before* calling pmb.helpers.repo.update().
Because otherwise update() defaults to all arches instead of
args.arch_native.
This caused the APKINDEX files for all arches to get downloaded, as
pmb.chroot.apk_static.init() calls alpine_apkindex_path() without
setting arch = args.arch_native explicitly.
Do not fail when an APKINDEX can not be downloaded, print a WARNING
instead. This matches, what apk does. Add a new allow_404 parameter to
pmb.helpers.http.download(), and use it in pmb.helpers.repo.update()
for downloading APKINDEX files. Cache the APKINDEX URLs that gave a 404
for the session, so we do not attempt to download these again.
This is needed for the new binary repository: the initial build is done
without existing APKINDEX files, so we must not fail in that case.
Change the cache format from args.cache["offline_msg_shown"] to
args.cache["pmb.helpers.repo.update"]["offline_msg_shown"]. This is in
preparation for saving more data in the cache of
pmb.helpers.repo.update in the next commit.
Multiple -mp arguments can be used to list multiple mirrors:
$ pmbootstrap -mp=first -mp=second chroot -- cat /etc/apk/repositories
This is needed for the new build infrastructure, so we can have a WIP
repository to which we push packages until all of them are up to date,
and then publish all of them at once. Software like KDE/Plasma Mobile,
which expect a lot of packages to be updated from one version to
another will not end up with a half-way through upgrade that way.
Obscure feature: it was possible to specify a local path as
--mirror-pmOS. It would then get mounted to /mnt/postmarketos-mirror
inside the chroot, and be specified as such in the generated
/etc/apk/repositories file.
I had used this once for some testing scripts, but I am sure nobody is
using this anymore. The same can be achieved with running a local http
server anyway:
<https://wiki.postmarketos.org/wiki/Installing_packages_on_a_running_phone>
Removing this makes it easier to support multiple postmarketOS mirrors
(next commit).
Add a new action that lists all aports, for which no binary packages
exist. Only list packages that can be built for the relevant arch
(specified with --arch). This works recursively: when a package can be
built for a certain arch, but one of its dependencies
(or their depends) can not be built for that arch, then don't list it.
This action will be used for the new sr.ht based build infrastructure,
to figure out which packages need to be built ahead of time (so we can
trigger each of them as single build job). Determining the order of the
packages to be built is not determined with pmbootstrap, the serverside
code of build.postmarketos.org takes care of that.
For testing purposes, a single package can also be specified and the
action will list if it can be built for that arch with its
dependencies, and what needs to be built exactly.
Add pmb/helpers/package.py to hold functions that work on both pmaports
and (binary package) repos - in contrary to the existing
pmb/helpers/pmaports.py (see previous commit) and pmb/helpers/repo.py,
which only work with one of those.
Refactoring:
* pmb/helpers/pmaports.py: add a get_list() function, which lists all
aports and use it instead of writing the same glob loop over and over
* add pmb.helpers.pmaports.get(), which finds an APKBUILD and parses it
in one step.
* rename pmb.build._package.check_arch to ...check_arch_abort to
distinguish it from the other check_arch function
