Get rid of config.mirror_alpine and mirrors_postmarketos and make sure
they get migrated over for existing users.
mirrors_postmarketos being a list was always a bit off, but now we have
per-aports mirrors which make a lot more sense for what we're trying to
do with systemd.

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.

Replace the "sanity_check" code with type checking built into the Config
__setattr__ operator.
This keeps all the Config related code in one place.

Add a new config section "mirrors", to replace the mirrors_alpine and
mirrors_postmarketos options. This will allow for more flexibility since
we can then handle the systemd staging repo (and others like plasma
nightly) with relative ease.
The loading/saving is fixed and now properly avoids writing out default
values, this way if the defaults are changed the user won't be stuck
with old values in their pmbootstrap.cfg.

Keeping the Config class in types seemed kinda weird and was just done
as a workaround to some cyclical imports. But now things are more in
shape let's move it to core.

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).

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.
Make sure users don't set systemd to "true" or other not allowed values
(allowed are "always", "default", "never").
Check for it:
* after loading the config
* when using 'pmbootstrap config systemd <newvalue>'
The provider selection for "pmbootstrap init" added in this commit
is a flexible way to offer UI/device-specific configuration options
in "pmbootstrap init", without hardcoding them in pmbootstrap.
Instead, the options are defined entirely in pmaports using APK's
virtual package provider mechanism. The code in pmbootstrap searches
for available providers and displays them together with their pkgdesc.
There are many possible use cases for this but I have tested two so far:
1. Selecting root provider (sudo vs doas). This can be defined entirely
in postmarketos-base, without having to handle this specifically in
pmbootstrap.
$ pmbootstrap init
[...]
Available providers for postmarketos-root (2):
* sudo: Use sudo to run root commands (**default**)
* doas: Use doas (minimal replacement for sudo) to run root commands
(Note: Does not support all functionality of sudo)
Provider [default]: doas
2. Device-specific options. My main motivation for working on this
feature is a new configuration option for the MSM8916-based devices.
It allows more control about which firmware to enable:
$ pmbootstrap init
[...]
Available providers for soc-qcom-msm8916-rproc (3):
* all: Enable all remote processors (audio goes through modem) (default)
* no-modem: Disable only modem (audio bypasses modem, ~80 MiB more RAM)
* none: Disable all remote processors (no WiFi/BT/modem, ~90 MiB more RAM)
Provider [default]: no-modem
The configuration prompts show up dynamically by defining
_pmb_select="<virtual packages>" in postmarketos-base, a UI PKGBUILD
or the device APKBUILD. Selecting "default" (just pressing enter)
means that no provider is selected. This allows APK to choose it
automatically based on the "provider_priority". It also provides
compatibility with existing installation; APK will just choose the
default provider when upgrading. The selection can still be changed
after installation by installing another provider using "apk".
Note that at the end this is just a more convenient interface for the
already existing "extra packages" prompt. When using pmbootstrap in
automated scripts the providers (e.g. "postmarketos-root-doas") can be
simply selected through the existing "extra_packages" option.
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.
* add my own build key
* enable the repo in the config
* update the README file
* Adjust testcase, that validates the keys and enable it in testcases_fast.sh
* Only save/load keys to/from the config file, which we ask for during
'pmbootstrap init', so the binary repo gets used even if a config file
already exists (this also removes a workaround, that deletes the work
folder path from the config dictionary before writing it)
* Download missing APKINDEX.tar.gz files with Python code, before
attempting to build packages (so we know which ones aleady exist in
the binary packages repository)
* Consider APKINDEX files older than 4 hours as outdated and download
them again (also in Python code)
* Provide 'pmbootstrap update' to force-update the APKINDEX files
* Travis: more logging output on failure
* Only allow keys from config_keys to be used by "pmbootstrap config"
TLDR: Always rebuild/install packages when something changed when executing "pmbootstrap install/initfs/flash", more speed in dependency resolution.
---
pmbootstrap has already gotten some support for "timestamp based rebuilds", which modifies the logic for when packages should be rebuilt. It doesn't only consider packages outdated with old pkgver/pkgrel combinations, but also packages, where a source file has a newer timestamp, than the built package has.
I've found out, that this can lead to more rebuilds than expected. For example, when you check out the pmbootstrap git repository again into another folder, although you have already built packages. Then all files have the timestamp of the checkout, and the packages will appear to be outdated. While this is not largely a concern now, this will become a problem once we have a binary package repository, because then the packages from the binary repo will always seem to be outdated, if you just freshly checked out the repository.
To combat this, git gets asked if the files from the aport we're looking at are in sync with upstream, or not. Only when the files are not in sync with upstream and the timestamps of the sources are newer, a rebuild gets triggered from now on.
In case this logic should fail, I've added an option during "pmbootstrap init" where you can enable or disable the "timestamp based rebuilds" option.
In addition to that, this commit also works on fixing #120: packages do not get updated in "pmbootstrap install" after they have been rebuilt. For this to work, we specify all packages explicitly for abuild, instead of letting abuild do the resolving. This feature will also work with the "timestamp based rebuilds".
This commit also fixes the working_dir argument in pmb.helpers.run.user, which was simply ignored before.
Finally, the performance of the dependency resolution is faster again (when compared to the current version in master), because the parsed apkbuilds and finding the aport by pkgname gets cached during one pmbootstrap call (in args.cache, which also makes it easy to put fake data there in testcases).
The new dependency resolution code can output lots of verbose messages for debugging by specifying the `-v` parameter. The meaning of that changed, it used to output the file names where log messages come from, but no one seemed to use that anyway.
