* Rename pmb/build/package.py to pmb/build/_package.py, so we can
access the functions it contains in testcases, and still use
pmb.build.package()
* Refactor the entire file. Instead of one big function that does
too many things, we have many small ones now, that are tested
in the testsuite and easier to modify
* Whenever building a package, pmbootstrap does not only build and
install the "makedepends" (like we did before), now it does the
same for the "depends". That's required to be compatible with
abuild. The old behavior can still be used with 'pmbootstrap
build --ignore-depends'.
* Because of that change, noarch packages can no longer be built in
the native chroot if we need them for a foreign chroot. A device-
package depending on a kernel would pull in the same kernel for
the native architecture otherwise.
* Running 'pmbootstrap build device-...' without '--ignore-depends'
and without a matching '--arch' displays a note that explains
this change to the user and tells how to use it instead.
* Noarch packages no longer get symlinked. That was only
implemented for packages built in the native chroot, and now that
is not always the case anymore. Symlinking these packages creates
packages with broken dependencies anyway (e.g.
device-samsung-i9100 can't be installed in x86_64, because
linux-samsung-i9100 is armhf only).
* Rename "carch" to "arch" wherever used. Naming it "carch"
sometimes is confusing with no benefit.
* Add a testcase for the aarch64 qemu workaround (because it failed
first and I needed to know for sure if it is working again).
* Improved some verbose logging, which helped with development of
this feature.
* Removed the old "build" test case (which was disabled in
testcases_fast.sh) as the new "build_package" test case covers its
functionallity.
* Only build indexes if the packages folder exists for that arch (Travis
couldn't run a test case otherwise)
This happens currently, when a makedepend is invalid:
ERROR: UnboundLocalError: local variable 'pkgname' referenced before assignment
With this patch, you get the meaning full error that should have been printed instead:
ERROR: Could not find package 'invalid-package' in the aports folder and could not find it in any APKINDEX
* Don't specify pkgnames from "provides" as dependencies
Always use the regular pkgname. That way, we avoid listing all
kinds of so: files as dependencies (because Alpine automatically
adds them as depends= to the package database). This fixes building
weston, and reproducing the build with `pmbootstrap challenge`.
Additional changes.
* Clear the parsed APKINDEX cache for the current pmbootstrap
session after building a package
* Avoid rebuilding a package, in case it was already built due to
circular dependencies
* Ignore `>`, `<`, `=` and `!` operators, when they are specified in
the dependencies. This was the desired behavior before, but it was
not implemented correctly (so it wouldn't ignore them everywhere).
Of course the real fix would be to honor these operators like apk
does. But this isn't feasible right now, and it should work for
most, if not all, our use-cases. I have documented this in the wiki
under build internals and if we happen to need correct operator
handling, we should do it then.
Minor other changes:
* `pmbootstrap parse_apkindex`: support optional package parameter to
only show the parsed content for one package.
* Support building most python APKBUILDs by replacing ${pkgname#py-}
properly
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.
