[ament_cppcheck] add --enable=style

[vincentrou]

I saw that coding style checks of cppcheck is not enabled : https://github.com/ament/ament_lint/blob/rolling/ament_cppcheck/ament_cppcheck/main.py#L145
For example, unused variables can be checked with this option.
Could you consider to add it ? I can make a PR for this.

Honestly, cppcheck is more-or-less completely disabled at the moment: https://github.com/ament/ament_lint/blob/rolling/ament_cppcheck/ament_cppcheck/main.py#L127 . It's just way too slow to use (cppcheck 2.x is something like 10x slower than cppcheck 1.9).

Additionally, even if we re-enable it, we already have 2 style checkers enabled for ROS 2 by default; uncrustify and cpplint. Adding a third one would most likely make it hard to please all of them.

That said, if you'd like to add a way to optionally enable style using cppcheck, please feel free to open a PR. We'll be happy to review.

@clalancette Is it possible to review the PR #407 ?

@clalancette any movement on this? Cppcheck is not really a style checker, but a static analysis tool, so it shouldn't overlap with uncrustify and cpplint. It performs a similar function to clang-check and clang-tidy.

As far as I know, current cppcheck is basically completely unusable for us. It takes many minutes to scan even a moderately-sized codebase; the last time I tried it on rclcpp, it took something like an hour to run. I think we'd be better off deprecating and (eventually) removing it, and switching to something like clang static analysis instead. Would that work for your use case?

Had a quick look at the latest version of cppcheck, but it seems like it's is absolutely terrible at finding header files, and the check time increases significantly with the amount of headers it is given. I tried passing it the compile_commands.json file (--project), but that can't be combined with ignore directories and it started spending a lot of time looking at for example gtest_vendor. It still didn't find the include files.

Here is a run I did by passing some of the more important include directories directly:
time /usr/bin/cppcheck -f --enable=all --check-level=normal --cppcheck-build-dir=cppcheck --template="{file}:{line}: {severity}: {message}" --inline-suppr -q -rp --suppress=missingInclude --suppress=missingIncludeSystem --suppress=unknownMacro -I ./install/include -I /install/include/rclcpp -I /install/include/rcl -I /install/include/rmw -I /install/include/rcutils -I /install/include/rcpputils -I /install/include/rcl_interfaces -I /src/rclcpp/rclcpp/test -j 16 ./src/rclcpp/rclcpp/

Which finished in under 2 mins on 16 cores, so probably more like 15mins on a smaller CI instance.

real    1m54.827s
user    18m20.304s
sys     0m4.491s

It does provide some valuable analysis, but it seems like a pain to decide how much include files to provide. There is an experimental feature that uses clang to generate the AST, perhaps that will be faster and better at locating include files. Currently it just spewed out the AST without any analysis as far as I could tell. I think I will revisit cppcheck at a later point.

I am not familiar with the 1.9.x version of cppcheck, but I ran with cppcheck(2.18.0) with rclcpp, this takes less than 10 seconds on my machine

@clalancette, can you verify this and take a look again on this ticket when you have time?
