Summary: Fixes T5097. When linting a large list of paths (e.g., with `--everything`), do this internally: $chunks = array_chunk($paths, 32); foreach ($chunks as $chunk) { $this->lintChunk($chunk); } This keeps the advantages of parallelism and artifact sharing for future-based linters, without having memory usage grow in an unbounded way. These callbacks changed: - `willLintPath()`: Useless, no meaningful implementations. Internalized the required side effect and broke the hook. - `didRunLinters()`: Now useless, with no meaningful implementations. Broke the hook. - `didLintPaths()`: New hook which executes opposite `willLintPaths()`. - `lintPath()`: Linters no longer need to implement this method. XHPAST now has an explicit way to release shared futures. These minor changes also happened: - Formalized the "linter ID", which is a semi-durable identifier for the cache. - Removed linter -> exception explicit mapping, which was unused. We now just collect exceptions. - We do the `canRun()` checks first (and separately) now. - Share more service call profiling code. - Fix an issue where the test harness would use the path on disk, even if configuration set a different path. Test Plan: - Ran `arc lint --everything` in `arcanist/`. - With no chunking, saw **unstable** memory usage with a peak at 941 MB. - With chunk size 32, saw **stable** memory usage with a peak at 269 MB. - With chunk size 8, saw **stable** memory usage with a peak at 180 MB. - Ran with `--trace` and saw profiling information. - Created this diff.
