Rename it from "Compilation" to "Build", as it's shorter and takes less
space in GitHub UI.
Remove GCC8 build configuration, as it does not add value: GCC9
build provides compilation on new compiler, while other Ubuntu builds
cover compilation on default compilers.
Implements new script (count-bugs.py) for peeking inside clang static
analyzer's report and print just a summary.
If number of detected bugs goes beyond the limit, script will return
with error code 1, thus failing the CI run. The upper limit is set to
113, which is current result of static analysis in our CI environment
(local run is likely to indicate different number); upper limit will
be updated in time, as issues get fixed or new compiler (detecting more
bugs) will be introduced.
This commit includes also slight modifictaions to count-warnings.py
script, to keep the both scripts outputting in similar format.
This way it will be possible to prevent users from introducing new
warnings. As new fixes will be upstreamed, the maximum limit of
allowed warnings should be taken lower and lower, so this script
could be eventually replaced by -Werror.
So far it consists of following builds:
- GCC 9.1 (Ubuntu 18.04)
- GCC 8.3 (Ubuntu 18.04)
- GCC 7.4 (Ubuntu 18.04 default)
- GCC 5.4 (Ubuntu 16.04 default)
- Clang 10.0 (macOS 10.14 Mojave default)
- Clang 6.0 (Ubuntu 18.04)
Workflow also defines static code analysis using Clang 6 (Ubuntu 18.04),
which does not indicate results directly in PRs yet, but uploads a
static analysis report as a build artifact.
