From f31c5b16eeec32924b28cb2de230937a1abbe5f7 Mon Sep 17 00:00:00 2001 From: Anna Henningsen Date: Tue, 12 Nov 2019 18:33:37 +0000 Subject: [PATCH] src: enhance feature access `CHECK`s during bootstrap This adds `CHECK`s verifying that bootstrapping has finished before environment variables are accessed or handles/requests are created. The latter complements a pair of existent checks, but fails earlier and thus gives information about the call site, effectively addressing the TODO comment there. --- src/handle_wrap.cc | 1 + src/node.cc | 3 ++- src/node_env_var.cc | 5 +++++ src/req_wrap-inl.h | 1 + 4 files changed, 9 insertions(+), 1 deletion(-) diff --git a/src/handle_wrap.cc b/src/handle_wrap.cc index 888640e9493d8e..fc84ca19bb2517 100644 --- a/src/handle_wrap.cc +++ b/src/handle_wrap.cc @@ -116,6 +116,7 @@ HandleWrap::HandleWrap(Environment* env, handle_(handle) { handle_->data = this; HandleScope scope(env->isolate()); + CHECK(env->has_run_bootstrapping_code()); env->handle_wrap_queue()->PushBack(this); } diff --git a/src/node.cc b/src/node.cc index 5a8e6ea8c07982..5379b42b578c1c 100644 --- a/src/node.cc +++ b/src/node.cc @@ -344,7 +344,8 @@ MaybeLocal Environment::RunBootstrapping() { // Make sure that no request or handle is created during bootstrap - // if necessary those should be done in pre-execution. - // TODO(joyeecheung): print handles/requests before aborting + // Usually, doing so would trigger the checks present in the ReqWrap and + // HandleWrap classes, so this is only a consistency check.
