I've done some refactoring while debugging #209.
* Unused file `pmb/build/crosscompiler.py` removed (that was a
left over from `_pmb_build_in_native_chroot` hack
* Do verbose logging in distccd, when `pmbootstrap --verbose` is
being invoked
* Restart distccd, when the commandline has changed (e.g. when the
currently running version was not verbose, and the new one is
verbose.) Prior to this change, it only got restarted, when the
architecture changed (so it did not allow changing the job count
on the fly for example).
* Insert missing whitespace in arguments help.
This is important for the binary repository scripts, so it's feasible
to test the binary package build and challenge process locally without
setting up a new chroot whenever changing the repo URLs.
Also it behaves a bit more intuitively, because it really uses the
repo URL specified on the commandline, even when the chroot is already
set up.
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 It doesn't only consider packages outdated with old pkgver/pkgrel combinations, but also packages, where a source file has a newer timestamp, than the built package has.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 Then all files have the timestamp of the checkout, and the packages will appear to be outdated.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problem once we have a binary package repository, because then the packages from the binary repo will always seem to be outdated, if you just freshly checked out the repository.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.
* Minimum version: 2.7.2 (which fixes two CVEs)
* Check the minimum apk version before doing something with apk and
before entering the chroot manually (previously, it has just checked
the apk-tools-static version, which gets used to set up the chroot)
* Reword the message for an outdated APK version. Most likely it is
just the outdated http cache, instead of a man-in-the-middle attack.

* 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().
* 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).
* Two new functions for getting a list of files and their timestamps
in the repo, and diffing that information to get a list of changed
files: pmb.helpers.repo.files() and pmb.helpers.repo.diff().
(I've put it in the helpers folder, because it is not specific to
one chroot, but to all chroots at once.)
* pmbootstrap challenge (new command introduced a few commits back to
verify, that the contents of an APK file are deterministic) uses
these functions to a) support subpackages and b) optionally
output a list of changed files (this gets used in the pmbuilder
script, which lives outside of this repository).
This commit is progress for #64 again.
We have "lazy reproducible builds" now. What I mean by that is, that
the resulting "apk" archive is not fully reproducible, but all binaries
inside it are. This is necessary to kick-off the binary repo, which is
in turn required to get the testsuite going on Travis. Read #64 for more
information.
Usage:
```
pmbootstrap build hello-world --buildinfo
pmbootstrap challenge /tmp/path/to/hello-world-1-r2.apk
```
The "--buildinfo" parameter generates a "buildinfo.json", which contains
the versions of all dependencies. It is not very optimizied, so this
is a performance bottleneck and takes 10 seconds (which is quite much
considering that the hello-world package builds in less than a second).
This can be improved in the future, and then the buildinfo parameter
may become the default.
* allows to build/extract/list initramfs, add/del hook
* rebuild the initfs whenever running install or trying to flash/boot it
* flasher flash/boot: automatically set up a minimal rootfs with kernel and initfs,
if it does not exist yet
pmb.chroot.apk.installed() used to return only the explicitly installed
packages. This is not good enough for the initfs check functions (and
especially for the "lazy reproducible builds", from which branch this
commit was cherry picked).
This commit introduces more noise for the logfile - if this becomes
a problem, raise your voice in the issues tracker and we'll do something
about it.
(This commit also changes minor code styling in other files, I did
not run autopep8 last time, because flake8 didn't complain...)
...also increase the default line count to 30, so it's easier to
spot an error if you didn't have the log open when it happened.
This parameter also works for 'pmbootstrap log_distccd', for consistency.
