With recent rework in postmarketos-initramfs, we no longer need to mount
the /boot partition in the initramfs (assuming initramfs-extra is not
used). On devices that boot without accessing the boot file system (e.g.
Android boot images, fastboot, ...), that makes it possible to install
postmarketOS on a single (potentially encrypted) partition that contains
both root (/) and /boot files.
This avoids the extra complexity of the subpartition setup we usually use
on such devices, and also avoids having to flash two partitions (when using
--split to avoid the subpartitions).
Add a --single-partition option to pmbootstrap install that allows
installing postmarketOS in this mode. For now this is just an option that
must be selected explicitly, in the future we could choose to make this the
default for Android-based devices with a large enough boot partition.

Write some basic parser tests for deviceinfo. The parser is quite basic
so there isn't much to test yet. Expecting this to gain features as we
look at e.g. making the parser the "source of truth" for the deviceinfo
format.

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.
Add some exhaustive unit testing to validate that these types behave as
expected.
And fix a few bugs uncovered by the tests.

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.

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.

Use a different binary repo depending on the source repository for the
package. This makes it possible to split out systemd packages into their
own repository.

Not sure if we should allow flash_method to be unset, but eh, simplify
usage by adding the none fallback here.

Introduce a Deviceinfo class and use it rather than the dictionary. This
gives us sweet sweet autocomplete, and lays the foundation for having a
proper deviceinfo validator in the future.
Additionally, continue refactoring out args...

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).

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.
Made changes to limit the line length in following files,
- pmb/parse/_apkbuild.py
- pmb/parse/apkindex.py
- pmb/parse/binfmt_info.py
- pmb/parse/deviceinfo.py
- test/test_parse_apkbuild.py
Added the above files in E501 flake8 command list.
Substitute f-string for string concatenation.
In the future, device ports will be located in a subdirectory
below device/... (e.g. device/testing/device-...).
Replace all occurrences of device/* with a glob that checks the
subdirectories instead.
Note: To ensure that this always works properly we should also add some
checks that all devices are indeed located under one of the supported
subdirectories (i.e. testing/community/main).
Change the glob for pmaports to <aports>/**/APKBUILD.
This allows using subdirectories for organization outside of device/
as well.
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.
Display the resolved deviceinfo file path in exceptions from the
deviceinfo parser. Instead of messages like these:
RuntimeError: Please add 'deviceinfo_codename="lg-mako"' to: /home/user/.local/var/pmbootstrap/cache_git/pmaports/.gitlab-ci/testcases/../../device/device-lg-mako/deviceinfo
We get the more readable version:
RuntimeError: Please add 'deviceinfo_codename="lg-mako"' to: /home/user/.local/var/pmbootstrap/cache_git/pmaports/device/device-lg-mako/deviceinfo
deviceinfo_codneame holds the device's code name, so we can easily look
it up in the finished postmarketOS installation by reading
/etc/deviceinfo.
