The handling in `CppCheck::reportErr()` and `Executor::hasToLog()` was
slightly different. I hope this can somehow be shared after the executor
reworking.
We were also using a very inappropriate container for the error list
which caused a lot of overhead.
`-D__GNUC__ --debug-warnings --template=daca2 --check-library -j2
../test/testsymboldatabase.cpp`
Clang 15
main process `284,218,587` -> `175,691,241`
worker process `9,123,697,183` -> `8,951,903,360`
Moved the `FileSettings` out of the `Settings` and pass them around
explicitly. They can never be specified at the same time and are used
exclusively. The code hasn't been fully adjusted to reflect this as this
is only the refactoring without any functional changes.
`ImportProject` is not needed outside of the command-line parsing so we
do not need it inside the `Settings` at all. We only use the
`fileSettings` in the executors.
The allocation invokes some heavy ValueFlow computations. We just want
to generate an unconditional error from the analysis so use some lighter
code which does the same.
`TestThreadExecutorFiles::deadlock_with_many_errors`
Before:
```
real 0m23.517s
user 0m33.453s
sys 0m2.297s
```
After:
```
real 0m5.051s
user 0m6.234s
sys 0m0.422s
```
This is a step onto leveraging the `ThreadExecutor` implementation for
`ProcessExecutor` which is a follow-up to #4870. We need to have the
proper test coverage and the existing implementations working as
expected before we move to the shared code.
Fixes:
- added `--showtime=` tests for all executor implementations
- only print `--showtime=summary` once at the end
- prevents `--showtime=` by multiple threads to be written at the same
time - essentially breaking the output
- reset the timer results before each test
- deprecated `top5` in favor of `top5_file`
- fixed printing for all executors except `ProcessExecutor`
I need to add parameters to some `check()` functions in the tests and
things are already pretty messy with having to specify all the default
values - readability aside.
