This commit rewrites initialisation of the "shared queue" and
in effect prevents from double execution of "core/core.js" and
"core/error.js".
Previously both of these files were executed every time a "JsRuntime"
was created. That lead to a situation where one copy of each script
was included in the snapshot and then another copy would be
executed after loading the snapshot.
Effectively "JsRuntime::shared_init" was removed; instead execution
of those scripts and actual initialisation of shared queue
was split into two helper functions: "JsRuntime::js_init" and
"JsRuntime::share_queue_init".
Additionally stale TODO comments were removed.
This commit migrates all ops to use new resource table
and "AsyncRefCell".
Old implementation of resource table was completely
removed and all code referencing it was updated to use
new system.
Moves op_close and op_resources to deno_core::ops and exports them.
Adds serde dependency to deno_core and reexports it.
Moves JS implementation of those ops to Deno.core and reexports them in Deno.
Provides a concrete state type that can be dynamically added. This is necessary for op crates.
* renames BasicState to OpState
* async ops take `Rc<RefCell<OpState>>`
* sync ops take `&mut OpState`
* removes `OpRegistry`, `OpRouter` traits
* `get_error_class_fn` moved to OpState
* ResourceTable moved to OpState
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
