This avoids silly problems like broken debug code. When debugging, I don't first
want to have to debug the debug code! :P
With all debug options enabled, `test-js` outputs 858081 lines. This is too much
for Travis, so we need to throw the debug output away on Travis. Note that
this still preserves information like *which* test failed, as well as the
precise error message.
We currently have 16 endpoints. The IDs are typed by a human at creation time.
This check will detect with we ever use an endpoint ID twice.
Since the large irrelevant directories are ignored, this should be quick enough.
This removes the dependency on the dead language python2.
Also, when we upgrade the base linux image (in 2020 or maybe 2021?),
this entire thing can hopefully be removed.
Uploading the cache takes several minutes. This gives us a handy way to tell
which parts the worst culprits are.
The Toolchain cache seems to be the worst offender by far, because the binary
size nearly doubled when we upgraded from gcc9 to gcc10.
.. and make travis run it.
I renamed check-license-headers.sh to check-style.sh and expanded it so
that it now also checks for the presence of "#pragma once" in .h files.
It also checks the presence of a (single) blank line above and below the
"#pragma once" line.
I also added "#pragma once" to all the files that need it: even the ones
we are not check.
I also added/removed blank lines in order to make the script not fail.
I also ran clang-format on the files I modified.
This should give a significant boost to Travis speeds, because most of the
compile time is spent building the toolchain over and over again.
However, the toolchain (or libc or libm) changes only rarely,
so most rebuilds can skip this step.
The hashing has been put into a separate file to keep it
as decoupled as possible from BuiltIt.sh.
lint-shell-scripts searches over the repository looking for shell
scripts. On those found, shellcheck is run against them. If any linting
fails print those warnings and exit with a non-zero exit code.
Run this script automatically in Travis.
It seems like the newest Ubuntu supported by Travis is 16.04. The bundled
gcc is unable to compile the trendy and modern Serenity code, so let's try
to install a newer GCC on the CI bot. :^)
