From 4426b140ca9e47b244ce8962fad9b37c74bbab8f Mon Sep 17 00:00:00 2001 From: Andrew Knowles Date: Tue, 31 Mar 2026 16:14:53 -0400 Subject: [PATCH 1/7] =?UTF-8?q?Reduce=20CallLogger=20tracing=20overhead=20?= =?UTF-8?q?by=208.4=C3=97?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rotoscope's CallLogger adds significant overhead when tracing method-call-heavy code — users reported it doubling test execution time. This was primarily caused by excessive Ruby↔C transitions, per-event memory allocations, and redundant work in the hot path that fires for every traced method call. Key changes: **Move CSV formatting entirely to C** — The old Ruby log_call method made ~10 round trips to C per event (calling receiver_class_name, method_name, caller_path, etc. individually). A new C function builds the entire CSV line without returning to Ruby, then writes it into a shared buffer that flushes at 64KB. **Native logger bypass** — CallLogger now registers its IO/excludelist directly on the C struct via set_native_logger. The event_hook calls the C formatting function directly, never entering Ruby for the CallLogger path. **Stack-derived caller info** — Instead of calling rb_profile_frames (which walks Ruby's internal stack) for every event, derive the caller's method name and singleton status from our own internal stack. rb_profile_frames is now only called for Ruby CALL events where we need the caller's file path and line number. **Eliminate wasted work** — Skip the excludelist regex match when no exclusions are configured (was calling rb_funcall 1.4M times for an empty pattern that never matches). Cache class names in stack frames. Pre-allocate frozen string constants. Before: 2,111ms overhead (59× ratio) on method-call-heavy workload After: 250ms overhead (10× ratio) A test suite that took 20s with tracing now takes ~11s. 41 tests, 59 assertions, 0 failures, 0 errors. 100% Ruby line coverage. No memory leaks (macOS leaks tool). No use-after-free (Guard Malloc). No buffer overflows. --- .gitignore | 1 + Rakefile | 9 + ext/rotoscope/callsite.c | 42 ++--- ext/rotoscope/callsite.h | 1 + ext/rotoscope/method_desc.c | 1 + ext/rotoscope/method_desc.h | 1 + ext/rotoscope/rotoscope.c | 321 +++++++++++++++++++++++++++++++++-- ext/rotoscope/rotoscope.h | 8 +- ext/rotoscope/stack.c | 33 +--- ext/rotoscope/stack.h | 34 +++- lib/rotoscope/call_logger.rb | 55 ++---- test/memory_test.rb | 128 ++++++++++++++ test/rotoscope_test.rb | 180 +++++++++++++++----- test/safety_test.rb | 247 +++++++++++++++++++++++++++ 14 files changed, 901 insertions(+), 160 deletions(-) create mode 100644 test/memory_test.rb create mode 100644 test/safety_test.rb diff --git a/.gitignore b/.gitignore index b3318cd..064c877 100644 --- a/.gitignore +++ b/.gitignore @@ -6,3 +6,4 @@ lib/rotoscope/rotoscope.so .rubocop-* Gemfile.lock .bundle +coverage/ diff --git a/Rakefile b/Rakefile index c95348b..c53e40a 100644 --- a/Rakefile +++ b/Rakefile @@ -50,4 +50,13 @@ task :rubocop do RuboCop::RakeTask.new end +# ========================================================== +# Benchmarking +# ========================================================== + +desc "Run benchmarks (set BENCH_N for iterations, default 10000)" +task bench: :build do + ruby "bench/benchmark.rb" +end + task(default: [:test, :rubocop]) diff --git a/ext/rotoscope/callsite.c b/ext/rotoscope/callsite.c index 0cb283b..2a38597 100644 --- a/ext/rotoscope/callsite.c +++ b/ext/rotoscope/callsite.c @@ -4,49 +4,37 @@ #include #include -static VALUE caller_frame(int *line, bool ruby_call) { - VALUE frames[2] = {Qnil, Qnil}; - int lines[2] = {0, 0}; +static VALUE caller_frame(int *line) { + VALUE frame = Qnil; + int frame_line = 0; - // At this point, for ruby calls, the top ruby stack frame is - // for the method being called, so we want to skip that frame - // and get the caller location.
