Use the exact formatting suggested in COPYING file.
This change is basically a pretext to trigger a new clean build in
order to check if Coverity is capable of accepting new builds for
analysis finally.
When two files have the same number of warnings, they will appear
in the same order in the summary, making the diff between different
build logs smaller.
Most linters behave this way, so it will fit the users' expectations.
Make -m optional, this makes the script a little bit easier to use.
Behaviour of MAX_WARNINGS and using -1 to disable the check is
preserved.
This change allows the maximum issues to be passed in as an argument.
If nothing is passed, then the existing build-in maximum is
used.
Retaining the existing built-in value makes sense for home
users to keep track of their local build (otherwise they would have
to remember the prior number of warnings and pass that value
in for subsequent builds).
Motivation: until now the built-in maximum covers the build permutation
that happens to generate the most warnings versus other builds.
In some cases new warnings may not be cause if they elicit a warning
from the lesser-warning build(s) or compilers, but not in the
maximum-warning build.
This change lets us tighten-down the warning uniquely for each build,
so we can be sure all new warnings are flagged to the developer.
This change makes a couple changes to the CI workflow:
- Adds more compiler coverage:
- gcc to MacOS (see note below)
- 32 and 64bit gcc and clang to Windows
- With more builds, this separates them into per-OS workflow YAMLs
(laying the foundation for more build environments: BSD? DOS? ... )
- Moves all functional commands from GitHub-syntax-YAML into scripts,
which (besides eliminating repeated code), now serve a dual-purpose
of being runnable outside of GitHub.
- One script takes care of listing dependent packages for the given
runtime environment
- Another script takes care of configuring and building
These scripts can be leveraged by a nightly build & asset generator in
the future.
Note: adding GCC to MacOS is now "correct" from a build perspective,
however to keep this PR focussed on the CI workflow I have not included
the coreMIDI / AppleBlocks code-fixes here (so for now, the gcc macOS
builds will fail; we will merge the coreMIDI / AppleBlocks later
depending on how upstream wants to handle it).
Upstream svn/trunk just introduced a bunch of new warnings.
Piggy-back change to interpret "From:" lines in SVN to be imported as
proper authorship information.
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.
