doc: Fix incorrect C++ named args #22981

maflcko · 2021-09-15T12:20:35Z

Incorrect named args are source of bugs, like #22979.

Fix that by correcting them and adjust the format, so that clang-tidy can check it.

maflcko · 2021-09-15T12:23:29Z

Setup clang-tidy:

apt install clang-tidy bear clang
./autogen.sh && ./configure --with-incompatible-bdb CC=clang CXX=clang++
make clean && bear make -j $(nproc)     # For bear 2.x
make clean && bear -- make -j $(nproc)  # For bear 3.x

Full test:

( cd ./src/ && run-clang-tidy  -j $(nproc) )

Diff test:

git diff | ( cd ./src/ && clang-tidy-diff -p2 -j $(nproc) )

Concept ACK, being able to check these automatically with a tool is a good idea.

we should be integrating this into the CI at some point soon.

Happy to review a pull doing this. Though, I think it is also acceptable to run it only once before every major release.

I think we should first make sure our argument names make sense, then do this.

practicalswift · 2021-10-20T08:33:47Z

Concept ACK

jnewbery · 2021-11-05T07:29:06Z

Concept ACK. Should we document the required comment style somewhere in the developer docs?

maflcko · 2021-11-05T09:16:23Z

Happy to document the style in a follow-up. I have one follow-up myself that adjusts the style of existing args. The goal of this pull is to replace wrong names with correct names.

tACK fa7efa0

The commands described in #22981 (comment) ran successfully.

And after clang-tidy-10 returned without an error, I changed a commented named argument in a function, reran it, and the error was identified.

Should compile_commands.json be added to .gitignore ?

maflcko · 2021-11-11T17:46:18Z

Should compile_commands.json be added to .gitignore ?

Yeah, will do on the next force push or the next follow-up pull, unless someone beats me to it.

Good catch. Fixed in #23525

Rebased to get rid of already fixed instances. Only 29 left in this pull for now.
