Replace "args.logfd" with "pmb.helpers.logging.logfd" in order to avoid
passing "args" to all functions that only use it to write to logfd. This
is the first step to get rid of this args-passed-to-all-functions
pattern in pmbootstrap.
Alpine APKBUILDs have the concept of "provider priorities" that affect
the choice of the provider to install when multiple packages provide
a virtual package.
One use case for this is to allow installation of different firmware
versions. bq-paella can run unsigned firmware, therefore you have the
choice between using the original firmware from the manufacturer, or
a slightly newer version from Qualcomm for the Dragonboard 410c.
We add provides="firmware-qcom-msm8916-wcnss" (the "virtual package")
to both firmware-qcom-db410c-wcnss and firmware-bq-picmt-wcnss.
At this point, attempting to install "firmware-qcom-msm8916-wcnss"
would still fail with apk. (Because it does not know which provider
to install.)
To pick a default we can set e.g. provider_priority=100 for
firmware-qcom-db410c-wcnss (the slightly newer version).
In that case, firmware-qcom-db410c-wcnss should be installed by default.
However, the user can choose to do "apk add firmware-bq-picmt-wcnss"
to override the default choice in case of problems. In that case,
the conflicting firmware-qcom-db410c-wcnss will be automatically removed.
At the moment, pmbootstrap does not respect the "provider_priority" at all.
In the above case, it would always install "firmware-bq-picmt-wcnss"
during "pmbootstrap install" since that has the shortest name.
Extend the pmbootstrap code to pick a provider with the highest priority
(if any of the providers has a priority set).
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.
Replace the "Add topdir to import path" boilerplate lines in each test
file with a simple "import pmb_test". Use the "# noqa" comment if
"pmb_test" is not used further in the test file, so flake8 does not
complain about an unused module.
Make the path to the testdata available as pmb_test.const.testdata, and
use pmb.config.pmb_src to access the topdir in all tests.
This is in preparation for new "pmbootstrap status" related tests, which
will have shared test code in test/pmb_test/. Also, this makes the
pmbootstrap codebase more consistent with the bpo codebase, which has a
similar "import bpo_test" mechanism.
Since PR #1247 we are using the virtual package `.pmbootstrap` to mark
packages as not explcitly installed. In case `pmbootstrap` doesn't
finish the installation because of a bug, the `.pmbootstrap` virtual
package may not get uninstalled.
As virtual packages don't have the "timestamp" attribute set in the
package database (which indicates when the package was built), the
APKINDEX parser fails to parse them.
Changes:
* pmb.parse.apkindex.parse_next_block(): don't require the "timestamp"
attribute to be set (but the arch attribute instead, which is always
present)
* pmb.parse.apkindex.parse(): when a block does not have a `timestamp`
attribute, skip it, because it must be a virtual package.
* add test cases for both functions with a package database that
contains a virtual package.
* The APKINDEX parser used to return a dictionary with one package for
a given package name. This works for the installed packages database,
because there can only be one provider for a package. But when
parsing packages from binary repositories, we need to support
multiple providers for one package. It is now possible to get a
dictionary with either multiple providers, or just a single provider
for each package.
* Dependency parsing logic has been adjusted, to support multiple
providers. For multiple providers, the one with the same package
name as the package we are looking up is prefered. If there is none
(eg. "so:libEGL.so.1" is provided by "mesa-egl"), it prefers packages
that will be installed anyway, and after that packages that are
already installed. When all else fails, it just picks the first one
and prints a note in the "pmbootstrap log".
* Added testcases for all functions in pmb.parse.apkindex and
pmb.parse.depends
* pmbootstrap chroot has a new "--add" parameter to specify packages
that pmbootstrap should build if neccessary, and install in the
chroot. This can be used to quickly test the depencency resolution
of pmbootstrap without doing a full "pmbootstrap install".
Fixes#1122.
Fixes#955. Previously we did not look through all APKINDEXes while
looking for the package with a given name and the highest version.
This caused pmbootstrap to build packages even if they are in the
binary repo and up to date.
