...instead of running apk every time to get the list of installed
packages and their versions. The internal package database from
apk has the same format, as the extracted APKINDEX file (except
that it has more key-value pairs, which we ignore/do not need
right now). So the APKINDEX code has been extended to parse both
tar-packed APKINDEX files and regular text files in the APKINDEX
format.
This is required for #108, for a better detection of outdated
packages (because the internal package database saves the
package's timestamp, too). A nice benefit is, that this is faster
than calling apk every time and it doesn't fill up the log as much.
I've also used this improved function for determining the apk
version (for the outdated version check), and I've deleted
pmb.parse.other.package_split(), as it is not needed anymore.
* New commandline parameter --mirror-pmOS, where the binary repository
URL for postmarketOS can be specified (empty by default as of now,
this will be filled with the real URL once the repo works)
* Do not build packages, when they are in the binary repository and
the version of the package in the binary repository is up-to-date.
* Add a testcase for pmb.build.is_necessary().
...even if the pkgver and pkgrel have *not* changed. This should
make development much more intuitive. The detection works by looking
at the last modified timestamps, just like `make` does it.
* The supported architectures are inside the config now
* Symlinks get created for that list of supported architectures now.
* During initialization, the architecture from the selected device
gets checked against the list of supported architectures. When
it is not included, a meaningful exception gets raised.
* the aportgen and (cross-compiler) build tests make use of the
new variable now (they had armhf and aarch64 hardcoded previously).
