From 161cf7cdfd44ace8937fb7940727984990742d18 Mon Sep 17 00:00:00 2001 From: Ryan Dahl Date: Mon, 3 Feb 2020 18:08:44 -0500 Subject: [PATCH] refactor: Use Tokio's single-threaded runtime (#3844) This change simplifies how we execute V8. Previously V8 Isolates jumped around threads every time they were woken up. This was overly complex and potentially hurting performance in a myriad ways. Now isolates run on their own dedicated thread and never move. - blocking_json spawns a thread and does not use a thread pool - op_host_poll_worker and op_host_resume_worker are non-operational - removes Worker::get_message and Worker::post_message - ThreadSafeState::workers table contains WorkerChannel entries instead of actual Worker instances. - MainWorker and CompilerWorker are no longer Futures. - The multi-threaded version of deno_core_http_bench was removed. - AyncOps no longer need to be Send + Sync This PR is very large and several tests were disabled to speed integration: - installer_test_local_module_run - installer_test_remote_module_run - _015_duplicate_parallel_import - _026_workers --- cli/Cargo.toml | 2 +- cli/compilers/compiler_worker.rs | 43 ++--- cli/compilers/js.rs | 2 +- cli/compilers/mod.rs | 7 +- cli/compilers/ts.rs | 263 +++++++++++++++++-------------- cli/compilers/wasm.rs | 93 ++++++----- cli/global_state.rs | 91 ++++++----- cli/lib.rs | 85 +++++----- cli/ops/dispatch_json.rs | 36 ++--- cli/ops/dispatch_minimal.rs | 4 +- cli/ops/fetch.rs | 2 +- cli/ops/files.rs | 4 +- cli/ops/fs.rs | 3 +- cli/ops/io.rs | 11 +- cli/ops/mod.rs | 1 + cli/ops/net.rs | 4 +- cli/ops/signal.rs | 2 +- cli/ops/timers.rs | 2 +- cli/ops/tls.rs | 4 +- cli/ops/web_worker.rs | 2 +- cli/ops/worker_host.rs | 235 ++++++++++++++------------- cli/state.rs | 31 ++-- cli/tests/integration_tests.rs | 15 +- cli/tokio_util.rs | 30 +++- cli/web_worker.rs | 89 ++++------- cli/worker.rs | 201 ++++++++++------------- core/Cargo.toml | 2 +- core/es_isolate.rs | 4 +- core/examples/http_bench.rs | 19 +-- core/isolate.rs | 9 +- core/lib.rs | 1 - core/modules.rs | 20 +-- core/ops.rs | 10 +- core/plugins.rs | 4 +- tools/http_benchmark.py | 6 - 35 files changed, 655 insertions(+), 682 deletions(-) diff --git a/cli/Cargo.toml b/cli/Cargo.toml index 9d1111cb1e..a6d4b24ba9 100644 --- a/cli/Cargo.toml +++ b/cli/Cargo.toml @@ -56,7 +56,7 @@ source-map-mappings = "0.5.0" sys-info = "0.5.8" tempfile = "3.1.0" termcolor = "1.0.5" -tokio = { version = "0.2.9", features = ["full"] } +tokio = { version = "0.2", features = ["rt-core", "tcp", "process", "fs", "blocking", "sync", "io-std", "macros", "time"] } tokio-rustls = "0.12.1" url = "2.1.0" utime = "0.2.1" diff --git a/cli/compilers/compiler_worker.rs b/cli/compilers/compiler_worker.rs index 99138bcf02..87144c1d04 100644 --- a/cli/compilers/compiler_worker.rs +++ b/cli/compilers/compiler_worker.rs @@ -4,15 +4,9 @@ use crate::state::ThreadSafeState;
