When a br2-external tree has an issue, e.g. a missing file, or does not
have a name, or the name uses invalid chars, we report that condition by
setting the variable BR2_EXTERNAL_ERROR.
That variable is defined in the script support/scripts/br2-external,
which outputs it on stdout, and checked by the Makefile.
Before d027cd75d0, stdout was explicitly redirected to the generated
.mk file, with exec >"${ofile}" as the Makefile and Kconfig
fragments were generated each with their own call to the script, and
the validation phase would emit the BR2_EXTERNAL_ERROR variable in the
Makefile fragment.
But with d027cd75d0, both the Makefile and Kconfig fragments were now
generated with a single call to the script, and as such the semantics of
the scripts changed, and only each of the actual generators, do_mk and
do_kconfig, had their out put redirected. Which left do_validate with
the default stdout. Which would emit BR2_EXTERNAL_ERROR on stdout.
In turn, the stdout of the script would be interpreted by as part of the
Makefile. But this does not end up very well when a br2-external tree
indeed has an error:
- missing a external.desc file:
Makefile:184: *** multiple target patterns. Stop.
- empty external.desc file:
Config.in:22: can't open file "output/.br2-external.in.paths"
So we must redirect the output of the validation step to the
Makefile fragment, so that the error message is correctly caught by the
top-level Makefile.
Note that we don't need to append in do_mk, and we can do an overwrite
redirection: if we go so far as to call do_mk, it means there was no
error, and thus the fragment is empty.

As reported by a gitlab runtime test [1] and on the mailing list
[2], some runtime tests are failing on slow host machines when
the qemu-system-<arch> is missing on the host.
The boot-qemu-image.py script need to wait some time after
calling pexpect.spawn() in order to make sure that the qemu
process has been executed in start-qemu.sh.
If start-qemu.sh failed due to missing qemu-system binary
an exception will be thrown by child.expect() and should be
catched by the error handling (pexpect.EOF).
After spending a lot of time to investigate with Yann E. MORIN
[3]. It seems that short-lived child processes are a corner-case
that is not very correctly handled...
Without adding a sleep(1), child.expect() can trigger an
exception before setting the exitstatus of the spawned
process. This issue can be reproduced on a gitlab runner or
by adding "exit 1" in the first line of start-qemu.sh
(after the shebang).
There is even the same workaround in some pexpect examples [4].
Thanks to Yann for the help while investigating the issue.

This script is intended to be used by gitlab CI to test at runtime Qemu
images generated by Buildroot's Qemu defconfigs.
This allows to troubleshoot different issues that may be associated with
defective builds by lanching a qemu machine, sending root password,
waiting for login shell and then perform a shutdown.
This script is inspired by toolchain builder [1] and the Buildroot
testing infrastructure.
The gitlab CI will call this script for each defconfig build but only
Qemu defconfig will be runtime tested, all others defconfig are ignored.
Some Qemu defconfig must be used with a specific Qemu version (fork)
that is not always available, so the script doesn't error out when it
can't spawn a missing command. That condition is anyway printed in the
log.
Finally, the script start Qemu like it's done for the Buildroot
testing infrastructure (using pexpect).
Note:
We noticed some timeout issues with pexpect when the Qemu machine is
powered off. That's because Qemu process doesn't stop even if the
system is halted (after "System halted"). So the script doesn't error
out when such timeout occure. The behaviour depends on the architecture
emulated by Qemu.

make-4.3 shipped with a backward incompatible change in how sharp signs
are handled in macros. Previously, up to make 4.2, the sharp sign would
always start a comment, unless backslash-escaped, even in a macro or a
fucntion call.
Now, the sharp sign is no longer starting a comment when it appears
inside such a macro or function call. This behaviour was supposed to be
in force since 3.81, but was not; 4.3 fixed the code to match the doc.
As such, use of external toolchains is broken, as we use the sharp sign
in the copy_toolchain_sysroot macro, in shell variable expansion to
strip off any leading /: ${target\#/}.
Fix that by applying the workaround suggested in the release annoucement
[0], by using a variable to hold a sharp sign.

The config is missing the following packages:

This is needed for the videotestsrc plugin which provides

- BR2_PACKAGE_GST1_PLUGINS_BAD
This is needed for the debugutils plugin which provides
fakevideosink.
- BR2_PACKAGE_GST1_PLUGINS_BASE_PLUGIN_VIDEOTESTSRC
videotestsrcplugin used by the example pipeline.
- BR2_PACKAGE_GST1_PLUGINS_BAD_PLUGIN_DEBUGUTILS
fakevideosink plugin used by the example pipeline.
The sample was also amended to fix:
- no call to main.
- using autovideosink instead of fakevideosink. Using Fakevideoskink
is preferred because its primary purpose is for debugging and sample
pipelines. Autovideosink does not work because there is no video
output device.
- No function on_message. Without this function, the script fails
because of the missing function.
- The script sets the pipeline to Gst.State.EOS instead of
Gst.State.NULL which results in a failed pipeline state. When the
state is set to NULL, gstreamer automatically calls EOS. Manually
setting the pipeline state to EOS results in the following error:
Trying to dispose element sink, but it is in PLAYING instead of
the NULL state. You need to explicitly set elements to the NULL
state before dropping the final reference, to allow them to
clean up. A refcounting bug may also cause this problem in the
application or some element.
In addition, the default timeout is set too low and would result in a
test failure, this has been changed to 200 seconds.
These issues are now properly fixed, and the sample script passes.

Do you really need Crypt::SSLeay?
Starting with version 6.02 of LWP, https support was unbundled into
LWP::Protocol::https. This module specifies as one of its prerequisites
IO::Socket::SSL which is automatically used by LWP::UserAgent unless
this preference is overridden separately. IO::Socket::SSL is a more
complete implementation, and, crucially, it allows hostname
verification. Crypt::SSLeay does not support this. At this point,
Crypt::SSLeay is maintained to support existing software that already
depends on it.
However, it is possible that your software does not really depend on
Crypt::SSLeay, only on the ability of LWP::UserAgent class to
communicate with sites over SSL/TLS.
If are using version LWP 6.02 or later, and therefore have installed
LWP::Protocol::https and its dependencies, and do not explicitly use
Net::SSL before loading LWP::UserAgent, or override the default socket
class, you are probably using IO::Socket::SSL and do not really need
Crypt::SSLeay.
Before installing Crypt::SSLeay, you may want to try specifying a
dependency on LWP::Protocol::https.

The C program inside check-kernel-headers.sh has two checking mode: a
strict and a loose one.
In strict mode, we want the kernel headers version declared by the
user to match exactly the one of the toolchain.
In loose mode, we want the kernel headers version of the toolchain to
be greater than or equal to the one declared by the user: this is used
when we have a toolchain that has newer headers than the latest
version known by Buildroot.
However, in loose mode, we continue to show the "Incorrect kernel
headers version" message, even though we then return a zero error
code. This is very confusing: you see an error displayed on the
terminal, but the build goes on.
We fix that by first doing the loose check first, and returning 0 if
it succeeds. And then we move on with the strict check where we want
the version to be identical.
