This commit upgrades Github Actions workers to ubuntu-22.04
As part of that change, we (currently) no longer need the backports
nor toolchain-r/test PPAs, because ubuntu-22.04 include
recent-enough version of QEMU and gcc
Add a job to the Azure pipelines to run tests with coverage enabled, and
aggregate the test results in a folder of html pages showing the
coverage results overall, and per-file.
Future work is needed to take the published pipeline artifact for the
coverage results and display them somewhere interesting.
The toolchain is built in a previous stage, but once the Serenity stage
has begun, we have to re-pull the toolchain from the Azure cache. There
is a timing window where a cache-busting change can be commited between
these steps; to alleviate the affect this has, pull the toolchain ccache
so that the build only takes a few minutes instead of a couple hours.
'bootmode' now only controls which set of services are started by
SystemServer, so it is more appropriate to rename it to system_mode, and
no longer validate it in the Kernel.
Bootmode used to control framebuffers, panic behavior, and SystemServer.
This patch factors framebuffer control into a separate flag.
Note that the combination 'bootmode=self-test fbdev=on' leads to
unexpected behavior, which can only be fixed in a later commit.
As of the Clang 13 upgrade, we only need to build the toolchain once and
can use that toolchain for both x86_64 and i686. To do this, this breaks
the main Azure configuration into 3 "stages" (Lagom, Toolchain, and
Serenity), where the Serenity stage depends on the Toolchain stage.
This has the added benefit of uploading a new prebuilt toolchain cache
sooner than before, which should help alleviate pressure from PRs.
We bust the prebuilt cache when any header in e.g. LibC changes. Doing a
full toolchain rebuild probably isn't necessary, so this adds a separate
ccache to speed up toolchain builds.
Currently, the templated steps in Caches.yml rely on the environment
variable CCACHE_DIR being set to configure the ccache location. To
prepare for multiple ccache paths, do not rely on this environment
variable because only one ccache can use it at a time. Instead, pass
the path into the template as a parameter.
Replace the old logic where we would start with a host build, and swap
all the CMake compiler and target variables underneath it to trick
CMake into building for Serenity after we configured and built the Lagom
code generators.
The SuperBuild creates two ExternalProjects, one for Lagom and one for
Serenity. The Serenity project depends on the install stage for the
Lagom build. The SuperBuild also generates a CMakeToolchain file for the
Serenity build to use that replaces the old toolchain file that was only
used for Ports.
To ensure that code generators are rebuilt when core libraries such as
AK and LibCore are modified, developers will need to direct their manual
`ninja` invocations to the SuperBuild's binary directory instead of the
Serenity binary directory.
This commit includes warning coalescing and option style cleanup for the
affected CMakeLists in the Kernel, top level, and runtime support
libraries. A large part of the cleanup is replacing USE_CLANG_TOOLCHAIN
with the proper CMAKE_CXX_COMPILER_ID variable, which will no longer be
confused by a host clang compiler.
The on-target pipelines have a timeout of 6 hours to allow time for a
clean toolchain + Serenity build. Tests should time out much sooner than
that though.
