gitlab runners seem to be registering binfmt now (?), so this fixes an
issue where register() might return immediately because the OS (or ??)
took care of registration, but the qemu-<arch> binary wasn't added to
the chroot.
It seems like the gitlab runners will now automatically register archs
when binfmt is mounted (I'm not completely sure, it's really
hard/annoying to confirm using gitlab CI jobs and no direct access to
the runner)
In any case, checking if it's already registered fixes a problem where
CI fails with "File exists" when it tries to register the arch.
Remove /in-pmbootstrap inside chroots in "pmbootstrap shutdown" instead
of having it at a specific part of "pmbootstrap install".
Reasoning:
* With current approach, it didn't get removed in the on-device
installer chroot.
* This is less error prone than calling it multiple times in
"pmbootstrap install"
Touch the file /in-pmbootstrap in chroots so that we can avoid
performing automated actions that should only happen on a real device
(like flashing the kernel).
Support branches, so pmbootstrap won't fail if v20.05 is selected:
ERROR: You have an outdated version of the 'apk' package manager installed
(your version: 2.10.5-r1, expected at least: 2.12.1-r0).
Move the logic for this check to pmb.helpers.apk.check_outdated and
adjust the test.
This fixes the CI failure in test_crossdirect_rust, which uses the
stable channel. (My bad for not creating this patch earlier, while at
the same time explaining in the creating pmbootstrap release instructions,
that this minimum apk version should be adjusted.)
Remove "_static" from the variable name, as this version isn't just
used to compare apk-tools-static's version (used to set up chroot), but
also for regular apk-tools before entering chroots.
Replace the "kill_as_root" argument with a much simpler "sudo" argument
and remove the now obsolete check for the output mode of "kill_as_root".
"kill_as_root" would only get set to True if both conditions are met:
a) command is running with sudo
b) command is running with an output mode ("log" or "stdout") where
pmb.helpers.run_core would kill it if it does not output anything
before a timeout is reached
The new "sudo" argument just indicates if the command is running with
sudo (a), regardless of the output mode (b).
Do not attempt to upgrade packages in the rootfs chroot when running
"pmbootstrap install".
This was responsible for placing every single package in /etc/apk/world
(which should only hold the packages explicitly installed), because the
upgrade function was literally implemented as getting a list of
installed packages and explicitly running pmb.chroot.apk.install on each
of them. The intention was to rebuild these packages if they were outdated,
I guess I didn't realize that this makes /etc/apk/world unusable when I
introduced this three years ago in 51bdc243 ("Properly rebuild/install
packages when something changed").
Remove pmb.chroot.apk.upgrade altogether, because:
1) pmb.install.install builds and upgrades outdated pmaports
2) pmb.install.install is the only user of pmb.chroot.apk.upgrade
3) 'pmbootstrap init' is warning that the chroots do not get upgraded
automatically, so let's not go against that expectation. users who
want an updated rootfs chroot can simply run zap and install again.
Replace it with a call to pmb.helpers.repo.update, because we still need
to update the APKINDEX files before attempting to build/install the
generated list of packages.
Some Mediatek devices have a special 512-byte header around the zImage
which must be generated so the device boots.
Support for that exists for a while in postmarketOS but detection was
missing. Add that.
Add a question at the end of "pmbootstrap init", to ask if the user
wants to build outdated packages during "pmbootstrap install". Store the
result in the new pmbootstrap.cfg key "build_pkgs_on_install". I've put it at
the end, because it is a rather complicated question compared to the rest.
This is useful to speed up the installation for casual users who can now
avoid compiling packages. But also for the official images where we only
want to ship the official binary packages and not build anything
on-the-fly.
Add initial support for the on-device installer in pmbootstrap. Let
pmbootstrap create a regular split image, then prepare a new installer
rootfs and copy the previously generated rootfs image into the installer
rootfs. Put the installer rootfs into a new image, with reserved space.
There is more to do from here, such as disabling the generation of the
user account when using --ondev. But this requires support in
postmarketos-ondev first, so let's build that iteratively.

Migrate to workdir version 5 and move already built packages into the edge
channel subdir, for example:
$WORK/packages/x86_64/hello-world-1-r5.apk
to:
$WORK/packages/edge/x86_64/hello-world-1-r5.apk
The build.postmarketos.org code has already been adjusted to find built
packages in either directory structure.
Do not go through the pmb.chroot.init() code path when running
pmb.install.losetup.umount() inside pmb.chroot.shutdown(). This is not
necessary, as pmb.install.losetup.umount() only gets called if the
chroot is already initialized and /dev/loop-control is mounted inside
the chroot.
Not going through this code path is important for the upcoming workdir
migration patch. Without this fix, it will fail with the following if
running "pmbootstrap install" before the work migration:
ERROR: Could not figure out on which release channel the 'native' chroot is
Whenever initializing new chroots, save the date in $WORK/workdir.cfg.
Add pmb.config.workdir.chroots_outdated() to check if it's time to zap
the chroots or not (since we don't update them automatically). Mark them
as outdated after two days.
This will be the first check in "pmbootstrap status" (future patches).

While at it, also remove unnecessary "#!/usr/bin/env python3" in files
that only get imported, and adjust other empty/comment lines in the
beginnings of the files for consistency.
This makes files easier to read, and makes the pmbootstrap codebase more
consistent with the build.postmarketos.org codebase.
Remove in favor of similar, but more visible "--no-install" option for
"pmbootstrap flasher" and "pmbootstrap export".
It seems that the option wasn't really used by anybody, so let's just
remove it without a deprication period. If dear reader thinks otherwise
after this is merged, and is not happy with "--no-install", please state
your reasoning in a new issue, so we can discuss it.

Rust packaging is new and still a bit weird in Alpine and postmarketOS.
As of writing, we only have one package (squeekboard), and use cargo to
download the source of all dependencies at build time (several git
repositories!) and compile it. Usually, this is a no-go, but at least
until this is resolved properly, let's cache the downloads as suggested
in: https://doc.rust-lang.org/cargo/guide/cargo-home.html
Related: #1861
When initializing the building chroots, some symlinks are created to
/mnt/pmbootstrap* dirs. With upcoming rust-related symlinks, they will
point to subdirs in /mnt/pmbootstrap-rust, such as
/mnt/pmbootstrap-rust/registry/cache. Create this directory structure if
it does not exist.
Because of an APKINDEX subpkg parsing bug, pmbootstrap currently assumes
that "ktp-common-internals" provides "make". It fails with a cryptic
error when trying to build a package without an existing postmarketOS
binary packages mirror (like done in the build.postmarketos.org
testsuite):
File "/home/user/code/pmbootstrap/pmb/chroot/apk.py", line 174, in replace_aports_packages_with_path
package + "-" + data_repo["version"] + ".apk")
TypeError: 'NoneType' object is not subscriptable
Replace this error with a more meaningful message, that points to the
issue analyzing this bug.

Fix configure crash when building mozjs60 by mounting tmpfs as /dev/shm
in chroots. This is an important fix, because of this dependency chain,
that is currently broken in armhf and armv7 (see pmaports#244):
postmarketos-base -> networkmanager -> polkit -> mozjs60
Launch native cross compilers inside foreign chroot. Enable by default,
but allow disabling with --no-crossdirect for now. This option and the
distcc-sshd related code will be removed in the future.
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).
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.
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!
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`
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)
The test suite needed a `pmbootstrap shutdown` after running through,
before it could successfully run again.
Explanation:
This was caused by `test/test_pkgrel_bump.py`, which creates a
temporary work folder with every subfolder ("chroot_native",
"cache_apk_x86_64", ...) linked to the original work folder except for
the "packages" folder. At the end of the test case,
`pmbootstrap shutdown` gets executed and is expected to umount
everything as usual. But it does not umount anything because of the
symlinks, so `work/chroot_native/mnt/pmbootstrap-packages` points to
the fake packages folder of that test case, even after it is finished.
As a result, any test case that tries to access the packages folder in
the native chroot, will fail until `pmbootstrap shutdown` gets called.
Detailed Changes:
* Umount all folders inside the work folder, even if these are symlinks
* Remove obsolete reference to "disable timestamp based rebuilds" in a
comment in `test/test_pkgrel_bump.py`
* Run `pmbootstrap work_migrate` and `pmbootstrap shutdown` at the
beginning of `test/testcases_fast.sh`, in case the pkgrel_bump test
case was aborted before it could properly shutdown and to make it
more robust in general (user may have changed the mountpoints, work
folder may need to be migrated)
* change "pmbootstrap kconfig_check" to "pmbootstrap kconfig check"
* change "pmbootstrap menuconfig" to "pmbootstrap kconfig edit [-x|-g]"
(with legacy alias, because the first syntax was referenced to a lot)
* enable X11 interfaces: -x: xconfig, -g: gconfig
* new function to copy the xauthority file:
pmb.chroot.other.copy_xauthority()
* remove menufconfig() function from the kernel template and all kernel
aports ([skip ci] because it would rebuild all kernels and run out of
time). Alpine has dropped this as well, and it wouldn't work with the
new code anyway.
Device nodes in the chroots get created in a tmpfs, so they can be
created even if the filesystem where the chroot resides does not
support device nodes (#1317). In "pmbootstrap shutdown" we umount the
`dev` folder, which means all device nodes that were created inside
this folder are gone. This commit changes the code to actually recreate
the device nodes when using the chroot again.
Details:
* move `pmb.chroot.init.create_device_nodes` to
`pmb.chroot.mount.crete_device_nodes`
* don't call it in `pmb.chroot.init()` anymore, but in
`pmb.chroot.mount_dev_tmpfs()`
* Create the `null` device as well (`apk --initdb` also creates it on
`init`, but we don't call it after `shutdown`)
* As discussed in IRC/matrix, we're removing `linux-postmarketos-lts`
for now. The kernel isn't used right now, and we save lots of
maintenance effort with not updating it every week or so.
* new config option `"kernel"` with possible values:
`"downstream", "mainline", "stable"` (downstream is always
`linux-$devicename`)
* ask for the kernel during `pmbootstrap init` if the device package
has kernel subpackages and install it in `_install.py`
* postmarketos-mkinitfs: display note instead of exit with error when
the `deviceinfo_dtb` file is missing (because we expect it to be
missing for downstream kernels)
* device-sony-amami:
* add kernel subpackages for downstream, mainline
* set `deviceinfo_dtb`
* device-qemu-amd64: add kernel subpackages for stable, lts, mainline
* test cases and test data for new functions
* test case that checks all aports for right usage of the feature:
* don't mix specifying kernels in depends *and* subpackages
* 1 kernel in depends is maximum
* kernel subpackages must have a valid name
* Test if devices packages reference at least one kernel
* Remove `_build_device_depends_note()` which informs the user that
`--ignore-depends` can be used with device packages to avoid building
the kernel. The idea was to make the transition easier after a change
we did months ago, and now the kernel doesn't always get built before
building the device package so it's not relevant anymore.
* pmb/chroot/other.py:
* Add autoinstall=True to kernel_flavors_installed(). When the flag
is set, the function makes sure that at least one kernel for the
device is installed.
* Remove kernel_flavor_autodetect() function, wherever it was used,
it has been replaced with kernel_flavors_installed()[0].
* pmb.helpers.frontend.py: remove code to install at least one kernel,
kernel_flavors_installed() takes care of that now.
In order to get cross-compilers, we generate a few aports (e.g.
binutils-armhf, gcc-armhf) automatically from Alpine's aports.
pmbootstrap was already able to perform a git checkout of Alpine's
aports repository. But it needed to be manually updated. Otherwise
the `pmbootstrap aportgen` command could actually downgrade the aport
instead of updating it to the current version.
After thinking about adding a dedicated pmbootstrap command for
updating git repositories, I thought it would be better to not open
that can of worms (pmbootstrap as general git wrapper? no thanks).
The solution implemented here compares the upstream aport version of
the git checkout of a certain package (e.g. gcc for gcc-armhf) with the
version in Alpine's binary package APKINDEX. When the aport version is
lower than the binary package version, it shows the user how to update
the git repository with just one command:
pmbootstrap chroot --add=git --user -- \
git -C /mnt/pmbootstrap-git/aports_upstream pull
Changes:
* `pmb.aportgen.core.get_upstream_aport()`: new function, that returns
the absolute path to the upstream aport on disk, after checking the
version of the aport against the binary package.
* Use that new function in pmb.aportgen.gcc and pmb.aportgen.binutils
* New function `pmb.helpers.repo.alpine_apkindex_path()`: updates the
APKINDEX if necessary and returns the absolute path to the APKINDEX.
This code was basically present already, but not as function, so now
we have a bit less overhead there.
* `pmbootstrap chroot`: new `--user` argument
* `pmb.parse.apkbuild`: make pkgname check optional, as it fails with
the official gcc APKBUILD before we modify it (the current APKBUILD
parser is not meant to be perfect, as this would require a full shell
parsing implementation).
* Extended `test_aportgen.py` and enabled it by default in
`testcases_fast.sh`. Previously it was disabled due to traffic
concerns (cloning the aports repo, but then again we do a full KDE
plasma mobile installation in Travis now, so that shouldn't matter
too much).
* `testcases_fast.sh`: With "test_aport_in_sync_with_git" removed
from the disabled-by-default list (left over from timestamp based
rebuilds), there were no more test cases disabled by default. I've
changed it, so now the qemu_running_processes test case is disabled,
and added an `--all` parameter to the script to disable no test
cases. Travis runs with the `--all` parameter while it's useful to
do a quick local test without `--all` in roughly 2 minutes instead of
10.
* `aports/cross/binutils-*`: Fix `_mirror` variable to point to current
default Alpine mirror (so the aportgen testcase runs through).
## Introduction
In #1302 we noticed that `pmb.chroot.user()` does not escape commands
properly: When passing one string with spaces, it would pass them as
two strings to the chroot. The use case is passing a description with
a space inside to `newapkbuild` with `pmboostrap newapkbuild`.
This is not a security issue, as we don't pass strings from untrusted
input to this function.
## Functions for running commands in pmbootstrap
To put the rest of the description in context: We have four high level
functions that run commands:
* `pmb.helpers.run.user()`
* `pmb.helpers.run.root()`
* `pmb.chroot.root()`
* `pmb.chroot.user()`
In addition, one low level function that the others invoke:
* `pmb.helpers.run.core()`
## Flawed test case
The issue described above did not get detected for so long, because we
have a test case in place since day one, which verifies that all of the
functions above escape everything properly:
* `test/test_shell_escape.py`
So the test case ran a given command through all these functions, and
compared the result each time. However, `pmb.chroot.root()`
modified the command variable (passed by reference) and did the
escaping already, which means `pmb.chroot.user()` running directly
afterwards only returns the right output when *not* doing any escaping.
Without questioning the accuracy of the test case, I've escaped
commands and environment variables with `shlex.quote()` *before*
passing them to `pmb.chroot.user()`. In retrospective this does not
make sense at all and is reverted with this commit.
## Environment variables
By coincidence, we have only passed custom environment variables to
`pmb.chroot.user()`, never to the other high level functions. This only
worked, because we did not do any escaping and the passed line gets
executed as shell command:
```
$ MYENV=test echo test2
test 2
```
If it was properly escaped as one shell command:
```
$ 'MYENV=test echo test2'
sh: MYENV=test echo test2: not found
```
So doing that clearly doesn't work anymore. I have added a new `env`
parameter to `pmb.chroot.user()` (and to all other high level functions
for consistency), where environment variables can be passed as a
dictionary. Then the function knows what to do and we end up with
properly escaped commands and environment variables.
## Details
* Add new `env` parameter to all high level command execution functions
* New `pmb.helpers.run.flat_cmd()` function, that takes a command as
list and environment variables as dict, and creates a properly escaped
flat string from the input.
* Use that function for proper escaping in all high level exec funcs
* Don't escape commands *before* passing them to `pmb.chroot.user()`
* Describe parameters of the command execution functions
* `pmbootstrap -v` writes the exact command to the log that was
executed (in addition to the simplified form we always write down for
readability)
* `test_shell_escape.py`: verify that the command passed by reference
has not been modified, add a new test for strings with spaces, add
tests for new function `pmb.helpers.run.flat_cmd()`
* Remove obsolete commend in `pmb.chroot.distccd` about environment
variables, because we don't use any there anymore
* Add `TERM=xterm` to default environment variables in the chroot,
so running ncurses applications like `menuconfig` and `nano` works out of
the box
`-m` is for deleting local compiled packages, for which there is no
aport with the same version. Prior to this change, this only worked
for packages where no aport exists, or for packages that are newer
than the aports.
That is, because we used the usual APKINDEX parsing logic, which
ignores old packages in the APKINDEX and only returns the one with the
highest version (that makes sense during dependency resolution).
Changes:
* New `pmb.parse.apkindex.parse_blocks()` function that returns a raw
list of blocks, instead of the dict with removed duplicates with
lower version you get from the usual `.parse()` function.
* Renamed each of the zap flags and their descriptions to make clear
what they are doing now.
