Obscure feature: it was possible to specify a local path as
--mirror-pmOS. It would then get mounted to /mnt/postmarketos-mirror
inside the chroot, and be specified as such in the generated
/etc/apk/repositories file.
I had used this once for some testing scripts, but I am sure nobody is
using this anymore. The same can be achieved with running a local http
server anyway:
<https://wiki.postmarketos.org/wiki/Installing_packages_on_a_running_phone>
Removing this makes it easier to support multiple postmarketOS mirrors
(next commit).
-m is the Alpine mirror, -mp is the postmarketOS mirror. Use "URL" as
metavar and add help text that explains how to disable the postmarketOS
mirror (so all pmaports get built locally).
In pmb.helpers.package.get(), we are differentiating between packages
that do not exist at all, and packages that do not exist for the
specified architecture. Make sure to actuallyy download the foreign arch
APKINDEX files, before trying to find the packages in there. Otherwise
the "could not find aport, and could not find this package in any
APKINDEX" package would appear.
We ran into this when testing on sr.ht, because pmbootstrap runs on a
fresh install every time, where no old APKINDEX files are present
(which would work around the bug).
This was meant to be part of the previous commit already, and was
tested, but it was not submitted correctly. So here it is as separate
commit straight to master. It is trivial anyway.
Add a new action that lists all aports, for which no binary packages
exist. Only list packages that can be built for the relevant arch
(specified with --arch). This works recursively: when a package can be
built for a certain arch, but one of its dependencies
(or their depends) can not be built for that arch, then don't list it.
This action will be used for the new sr.ht based build infrastructure,
to figure out which packages need to be built ahead of time (so we can
trigger each of them as single build job). Determining the order of the
packages to be built is not determined with pmbootstrap, the serverside
code of build.postmarketos.org takes care of that.
For testing purposes, a single package can also be specified and the
action will list if it can be built for that arch with its
dependencies, and what needs to be built exactly.
Add pmb/helpers/package.py to hold functions that work on both pmaports
and (binary package) repos - in contrary to the existing
pmb/helpers/pmaports.py (see previous commit) and pmb/helpers/repo.py,
which only work with one of those.
Refactoring:
* pmb/helpers/pmaports.py: add a get_list() function, which lists all
aports and use it instead of writing the same glob loop over and over
* add pmb.helpers.pmaports.get(), which finds an APKBUILD and parses it
in one step.
* rename pmb.build._package.check_arch to ...check_arch_abort to
distinguish it from the other check_arch function
Move find_aport() and find_aport_guess_main() from pmb/build/other.py
to the new file pmb/helpers/pmaports.py.
Finding aports is not only needed when building packages, hence it
makes sense to move it out of pmb.build. The pmb/helpers/pmaports.py
file will have more pmaports related functions in a follow up commit.
Target arch is the system the package will run on. Host arch is the
system the package is compiled on.
For example kernel packages can be compiled on host arch x86_64 and
intended to run on target arch armhf. A build is necessary check
against host arch will always return True. The correct way is to check if
the package needs to be built for target arch.
Do not try to build and install dependencies for the package's
architecture when compiling in the "native" mode. That mode is
described here in detail:
https://wiki.postmarketos.org/wiki/Build_internals#Cross-compile_types
This makes it possible to cross compile kernels again, which need to
be built with GCC6. We have switched to Alpine's GCC6 package, but it is
not available for armhf/aarch64 on edge yet, because Alpine's build bots
are stuck (right now armhf is not even listed):

Huge thanks to ryang2478/Decatf for posting this patch in pmaports#138!
Clearly state which version is being used, and also display the message
when using build --force.
- Old:
WARNING: Package 'ubuntu-app-launch' in your aports folder has version
0_git20180604-r0, but the binary package repositories already have version
0_p20181101174257-r0! See also: <https://postmarketos.org/warning-repo2>
- New:
WARNING: package hello-world: aport version 1-r4 is lower than 1-r5 from
the binary repository. 1-r5 will be used when installing hello-world.

Find the main package by assuming it is a prefix of the subpkgname. We
do that, because in some APKBUILDs the subpkgname="" variable gets
filled with a shell loop and the APKBUILD parser in pmbootstrap can't
parse this right. (Intentionally, we don't want to implement a full
shell parser.)
This covers most use cases and saves a lot of build time. Can be
changed on demand. Again, this simplifies package building as part of
the new build infrastructure effort.
Use the device's architecture instead of noarch. Because the device
packages should never be built for other architectures, even if all
depends can be built for other arches as well.
This simplifies package building as part of the new build
infrastructure effort.
All existing pmaports will be changed shortly, along with a test case
in pmaports.
Set HOME to /root for commands started with pmb.chroot.root() and to
/home/pmos for commands started with pmb.chroot.user().
POSIX requires this variable to be set, see:
<http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap08.html>
And this prevents a crash in "adb", which takes and alternative code
path if HOME is not set, that does not work with musl (fixes#1638).
Thanks to @ryang2678 for figuring this out!
* create symlinks to the GCC8 patches (introduced in pmaports!35)
* link to the new vendorkernel reference wiki page
* use SPDX license in the license= field
* add comment above the compiler section of the APKBUILD
* remove empty line at the end of the APKBUILD
When the timeout occurs it is important to ensure clean up of child
processes. Killing only the direct process created by a command can
leave child processes running.
For example a pmbootstrap.py install will run apk add. This run command
creates multiple processes as follows:
(cmd line arguments snipped for readability)
$ ps -e -o pid,ppid,pgid,cmd
PID PPID PGID CMD
31738 23247 31738 python3 ./pmbootstrap.py -t 15 install --no-fde
31746 31738 31738 sudo env -i /bin/sh -c ... ;apk --no-progress add
31747 31746 31738 /bin/sh -c ... ;apk --no-progress add
31748 31747 31738 apk --no-progress add
The root process of the run command is PID 31746. We want to kill
the child processes too. Otherwise only running kill -9 31746 will leave
the processes 31747 and 31748 running.
* aportgen: modify code to allow generating gcc6-armhf and other gcc6
cross compiler packages
* package: when 'gcc6' is in the depends of a package, and the cross
compiling mode is "native" (as we do it with kernels), install the
gcc6 cross compiler instead of the usual one (gcc8)
Related: pmaports#103
Overview:
In order to execute foreign arch binaries on the host system, we are
using the Linux kernel's binfmt_misc feature in combination with
static builds of QEMU. Before this patch, the statically compiled
QEMU binaries were taken from Debian (mostly because I did not realize
that Alpine ships them as well). Now we can use the ones from the aport.
Benefits:
This allows us to easily update and patch the QEMU executables, we
don't need to be in sync with Debian's versions anymore.
Alpine's package is more modular, so we can save some download,
install, zap time, as well as disk space: setting up an armhf chroot
with pmbootstrap took ~102 MB before, now it's ~18 MB.
Detailed changes:
* Remove `cross/qemu-user-static-repack` aport
* Add `data/qemu-user-binfmt.txt` with the binfmt_misc flags for ELF
binaries of various arches (extracted from Debian's packaging)
* When parsing that file, don't write verbose messages to
`pmbootstrap log` anymore, only to the verbose log (can be enabled
with `pmbootstrap -v`)
* Rename `pmb.parse.arch.alpine_to_debian()` to ...`alpine_to_qemu()`
* Rename `arch_debian` to `arch_qemu`
This commit adds a test case, which makes sure that the KDE framework
and plasma framework version are always the same.
Additional changes:
* APKBUILD parser parses the URL now (that's the best way I found to
categorize the KDE aports in frameworks and other)
* Changed single quotes to double quotes in KDE APKBUILDs, so the
parser doesn't include the single quotes in the parsed result
* Added the test case to the gitlab CI config
With this patch, "pmbootstrap flasher" will fail with "the following
arguments are required: action_flasher". Without it, it just prints
"Done" and quits.
Overview:
Since Alpine updated to distcc 3.3 last week, pmbootstrap wasn't able to use
distcc for cross compilation anymore. It always falled back to running the
compiler in QEMU (which works, but is a lot slower). The reason for that is,
that distcc requires all compilers that are being used in a whitelist now.
This partially fixes CVE-2004-2687 in distccd, which allowed trivial remote
code execution by any process connecting to the distccd server. We only run
distccd on localhost, but still this can be used for privilege escalation of
sandboxed processes running on the host system (not part of pmbootstrap
chroots).
Because the CVE is only partially fixed (see the comment in
`pmb/chroot/distccd.py` for details), we make sure that only the building
chroots can talk to the distcc server by running distcc over ssh.
Details:
* Completely refactored `pmb/chroot/distccd.py` to run distcc over ssh
* Store the running distcc server's arguments as JSON now, not as INI
* Make debugging distcc issues easy:
* Set DISTCC_BACKOFF_PERIOD=0, so the distcc client will not ignore the
server after errors happened (this masks the original error!)
* New pmbootstrap parameters:
* `--distcc-nofallback`: avoids falling back to compiling with QEMU and not
throwing an error
* `--ccache-disable`: avoid ccache (when the compiler output is cached,
distcc does not get used)
* `--verbose` prints verbose output of the distcc too
* New test case, that uses the new pmbootstrap parameters to force
compilation through distcc, and shows the output of distcc and distccd in
verbose mode on error (as well as the log of sshd)
