Check if the pkgnames are sane in install_run_apk, right before running
apk. This makes sure that we really run it on all arguments that are
supposed to be packages / files and not options to apk.
Previously to this patch, pmbootstrap would pass a full dependency tree
to "apk add". It would use a virtual package to ensure only the right
packages get added to /etc/apk/world. For example:
apk add -u --virtual .pmbootstrap postmarketos-base device-asus-me176c \
postmarketos-ui-sxmo-de-sway device-asus-me176c-nonfree-firmware w3m \
sfeed clickclack firefox-esr font-noto font-noto-emoji gnome-icon-theme \
imv megapixels mobile-config-firefox ttyescape postmarketos-base-nofde \
eudev openssh postmarketos-mkinitfs postmarketos-mvcfg postmarketos-keys \
...
Instead of doing that, only pass the packages we want to install and let
apk figure out the dependencies. Most of the time we can even avoid
using the virtual package now.
== Remaining edge case: locally built packages
apk will only upgrade a package with the same pkgver + pkgrel but a
different build date if the full path to an apk file gets passed as
argument. So if the user built a package locally that will be installed,
or one of its dependencies then we still need to use a virtual package
and possibly pass a dependency to apk. Replace
replace_aports_packages_with_path() with packages_get_locally_built_apks()
to get a list of such packages and adjust install() and
install_run_apk() to use it.
Make the code easier to read by moving split_to_add_del() to a separate
function and do some related refactoring. A future patch will use it
twice in install().
Move "arch = ..." to the top of the function while at it, since it's
needed later in the function in 2 places and is not needed for figuring
out packages_with_depends, to_add and to_del.
Remove "# Add depends to packages" because it's obvious from the
packages_with_depends variable name, and getting to_add/to_del is a
different action that stood under the same comment.
install_is_necessary used to do the following things:
1. Error out if there's no binary package but pmb was invoked as
"pmbootstrap install" and build_pkgs_on_install is disabled.
2. Build the package if necessary.
3. Return if a package "needs to be installed" (Boolean or Float).
The only caller of the function is pmb.chroot.apk.install. It would not
add the package to the long "apk add" command if according to 3. it does
not need to be installed.
When I implemented this a few years ago, I probably thought it would be
useful to not unnecessarily pass packages to apk. But this actually
makes it more complicated and doesn't have a benefit, apk is perfectly
capable of recognizing which packages it had already installed.
Replace the function with a much simpler pmb.chroot.apk.install_build,
which only does 1. and 2. Change the order of the package, arch
arguments to match called functions pmb.parse.apkindex.package and
pmb.build.package.
