2024-11-06Ignore return value of `into_raw_fd`Nobuyoshi Nakada
Fix as the compiler orders: ``` warning: unused return value of `into_raw_fd` that must be used --> ../src/yjit/src/disasm.rs:123:21 | 123 | file.into_raw_fd(); // keep the fd open | ^^^^^^^^^^^^^^^^^^ | = note: losing the raw file descriptor may leak resources = note: `#[warn(unused_must_use)]` on by default help: use `let _ = ...` to ignore the resulting value | 123 | let _ = file.into_raw_fd(); // keep the fd open | +++++++ warning: unused return value of `into_raw_fd` that must be used --> ../src/yjit/src/log.rs:84:21 | 84 | file.into_raw_fd(); // keep the fd open | ^^^^^^^^^^^^^^^^^^ | = note: losing the raw file descriptor may leak resources help: use `let _ = ...` to ignore the resulting value | 84 | let _ = file.into_raw_fd(); // keep the fd open | +++++++ ``` Notes: Merged: https://github.com/ruby/ruby/pull/12009
2024-10-17YJIT: Add compilation log (#11818)Kevin Menard
* YJIT: Add `--yjit-compilation-log` flag to print out the compilation log at exit. * YJIT: Add an option to enable the compilation log at runtime. * YJIT: Fix a typo in the `IseqPayload` docs. * YJIT: Add stubs for getting the YJIT compilation log in memory. * YJIT: Add a compilation log based on a circular buffer to cap the log size. * YJIT: Allow specifying either a file or directory name for the YJIT compilation log. The compilation log will be populated as compilation events occur. If a directory is supplied, then a filename based on the PID will be used as the write target. If a file name is supplied instead, the log will be written to that file. * YJIT: Add JIT compilation of C function substitutions to the compilation log. * YJIT: Add compilation events to the circular buffer even if output is sent to a file. Previously, the two modes were treated as being exclusive of one another. However, it could be beneficial to log all events to a file while also allowing for direct access of the last N events via `RubyVM::YJIT.compilation_log`. * YJIT: Make timestamps the first element in the YJIT compilation log tuple. * YJIT: Stream log to stderr if `--yjit-compilation-log` is supplied without an argument. * YJIT: Eagerly compute compilation log messages to avoid hanging on to references that may GC. * YJIT: Log all compiled blocks, not just the method entry points. * YJIT: Remove all compilation events other than block compilation to slim down the log. * YJIT: Replace circular buffer iterator with a consuming loop. * YJIT: Support `--yjit-compilation-log=quiet` as a way to activate the in-memory log without printing it.
