Add a lint rule for torch/csrc/util/pybind.h include
We define specializations for pybind11 defined templates (in particular, PYBIND11_DECLARE_HOLDER_TYPE) and consequently it is important that these specializations *always* be #include'd when making use of pybind11 templates whose behavior depends on these specializations, otherwise we can cause an ODR violation. The easiest way to ensure that all the specializations are always loaded is to designate a header (in this case, torch/csrc/util/pybind.h) that ensures the specializations are defined, and then add a lint to ensure this header is included whenever pybind11 headers are included. The existing grep linter didn't have enough knobs to do this conveniently, so I added some features. I'm open to suggestions for how to structure the features better. The main changes: - Added an --allowlist-pattern flag, which turns off the grep lint if some other line exists. This is used to stop the grep lint from complaining about pybind11 includes if the util include already exists. - Added --match-first-only flag, which lets grep only match against the first matching line. This is because, even if there are multiple includes that are problematic, I only need to fix one of them. We don't /really/ need this, but when I was running lintrunner -a to fixup the preexisting codebase it was annoying without this, as the lintrunner overall driver fails if there are multiple edits on the same file. I excluded any files that didn't otherwise have a dependency on torch/ATen, this was mostly caffe2 and the valgrind wrapper compat bindings. Note the grep replacement is kind of crappy, but clang-tidy lint cleaned it up in most cases. See also pybind/pybind11#4099 Signed-off-by: Edward Z. Yang <[email protected]> [ghstack-poisoned]
