This commit makes error objects more resistant to
prototype tampering.
This bug was found when updating the deno_std Node compatibility
layer to Node 18. The Node test 'parallel/test-assert-fail.js'
was breaking std's assertion library.
Refs: https://github.com/denoland/deno_std/pull/2585
This commit removes "compat" mode. We shipped support for "npm:" specifier
support in v1.25 and that is preferred way to interact with Node code that we
will iterate and improve upon.
Previously `jsxImportSource` was resolved relative to the config file
during graph building, and relative to the emitted module during
runtime.
This is now fixed so that the JSX import source is resolved relative to
the module both during graph building and at runtime.
This commit splits `Deno.upgradeHttp` into two different APIs, because
the same API is currently overloaded with two different functions. Flash
requests upgrade immediately, with no need to return a `Response`
object. Instead you have to manually write the response to the socket.
Hyper requests only upgrade once a `Response` object has been sent.
These two behaviours are now split into `Deno.upgradeHttp` and
`Deno.upgradeHttpRaw`. The latter is flash only. The former only
supports hyper requests at the moment, but can be updated to support
flash in the future.
Additionally this removes `void | Promise<void>` as valid return types
for the handler function. If one wants to use `Deno.upgradeHttpRaw`,
they will have to type cast the handler signature - the signature is
meant for the 99.99%, and should not be complicated for the 0.01% that
use `Deno.upgradeHttpRaw()`.
This commit changes the `Deno.serve` function signature to be more
versatile and easier to use. It is now a drop in replacement for
std/http's `serve`.
The input validation has also been reworked.
Previously if a user specified a content-length header for an POST
request without a body, the request would contain two `content-length`
headers. One added by us, and one added by the user.
This commit ignores all content-length headers coming from the user,
because we need to have the sole authority on the content-length because
we transmit the body.
This commit changes "npm:" specifier handling to respect "--cached-only" flags and adds "Download" messages for npm registry api calls.

Adds error event dispatching for queueMicrotask(). Consequently unhandled errors are now reported with Deno.core.terminate(), which is immune to the existing quirk with plainly thrown errors (#14158).
This adds an init subcommand to that creates a project starter similar to cargo init.
```
$ deno init my_project
Project initialized
Run these commands to get started:
cd my_project
deno run main.ts
deno run main_test.ts
$ deno run main.ts
Add 2 + 3 5
$ cat main.ts
export function add(a: number, b: number): number {
return a + b;
}
if (import.meta.main) {
console.log("Add 2 + 3", add(2, 3));
}
$ cat main_test.ts
import { assertEquals } from "https://deno.land/std@0.151.0/testing/asserts.ts";
import { add } from "./main.ts";
Deno.test(function addTest() {
assertEquals(add(2, 3), 5);
});
```

- Remove first argument and use "fetch" field options instead
- Update type declarations
- Add more documentation
Welcome to better optimised op calls! Currently opSync is called with parameters of every type and count. This most definitely makes the call megamorphic. Additionally, it seems that spread params leads to V8 not being able to optimise the calls quite as well (apparently Fast Calls cannot be used with spread params).
Monomorphising op calls should lead to some improved performance. Now that unwrapping of sync ops results is done on Rust side, this is pretty simple:
```
opSync("op_foo", param1, param2);
// -> turns to
ops.op_foo(param1, param2);
```
This means sync op calls are now just directly calling the native binding function. When V8 Fast API Calls are enabled, this will enable those to be called on the optimised path.
Monomorphising async ops likely requires using callbacks and is left as an exercise to the reader.
This commit adds "ext/node" extension that implementes CommonJS module system.
In the future this extension might be extended to actually contain implementation of
Node compatibility layer in favor of "deno_std/node".
Currently this functionality is not publicly exposed, it is available via "Deno[Deno.internal].require"
namespace and is meant to be used by other functionality to be landed soon.
This is a minimal first pass, things that still don't work:
support for dynamic imports in CJS
conditional exports
This commit adds new "import.meta.resolve()" API which
allows to resolve specifiers relative to the module the API
is called in. This API supports resolving using import maps.
- "SpawnOutput" extends "ChildStatus" instead of composing it
- "SpawnOutput::stdout", "SpawnOutput::stderr", "Child::stdin",
"Child::stdout" and "Child::stderr" are no longer optional, instead
made them getters that throw at runtime if that stream wasn't set
to "piped".
- Remove the complicated "<T extends SpawnOptions = SpawnOptions>"
which we currently need to give proper type hints for the availability of
these fields. Their typings for these would get increasingly complex
if it became dependent on more options (e.g. "SpawnOptions::pty"
which if set should make the stdio streams unavailable)
Relanding #12994
This commit adds support for "unhandledrejection" event.
This event will trigger event listeners registered using:
"globalThis.addEventListener("unhandledrejection")
"globalThis.onunhandledrejection"
This is done by registering a default handler using
"Deno.core.setPromiseRejectCallback" that allows to
handle rejected promises in JavaScript instead of Rust.
This commit will make it possible to polyfill
"process.on("unhandledRejection")" in the Node compat
layer.

When a dynamically imported module gets resolved, any code that comes after an
await import() to that module will continue running. However, if that is the
last code in the evaluation of another dynamically imported module, that second
module will not resolve until the next iteration of the event loop, even though
it does not depend on the event loop at all.
When the event loop is being blocked by a long-running operation, such as a
long-running timer, or by an async op that might never end, such as with workers
or BroadcastChannels, that will result in the second dynamically imported module
not being resolved for a while, or ever.
This change fixes this by running the dynamic module loading steps in a loop
until no more dynamic modules can be resolved.
This commit adds support for unstable FFI
callbacks. A callback is registered using
the `Deno.UnsafeCallback` API.
The backing memory for the callback can
be disposed of using `Deno.UnsafeCallback#close`.
It is not safe to pass the callback after calling
close.
Callbacks from other than the isolate thread
are not supported.

This commit adds brand checking to EventTarget. It also fixes a
bug where deno would crash if an abort signal was aborted on the
global addEventListener().
This commit updates the custom inspect function for URL objects
to pass the inspect options through so that the context is
propagated and the resulting indentation is correct.
Fixes: https://github.com/denoland/deno/issues/14171
This commit changes default default behavior of type checking
for several subcommands.
Instead of type checking and reporting type errors only for local
files, the type checking is skipped entirely. Type checking can
still be enabled using the "--check" flag.
Following subcomands are affected:
- deno cache
- deno install
- deno eval
- deno run
This commit adds "Deno.core.setFormatExceptionCallback" which
can be used to provide custom formatting for errors. It is useful
in cases when user throws something that is non-Error (eg.
a string, plain object, etc).
This commit improves the permission descriptor validation by
explicitly checking for object types and using optional
chaining when creating error messages in case the descriptor
is not an object.
Fixes: https://github.com/denoland/deno/issues/14675
This commit changes default mode of type-checking to "local"
and adds "--check" flag to following subcommands:
- deno bench
- deno bundle
- deno cache
- deno compile
- deno eval
- deno install
- deno test
This commit removes "WorkerOptions.deno" option as a boolean,
as well as "WorkerOptions.deno.namespace" settings. Starting
with this commit all workers have access to "Deno" namespace
by default.
This commit fixes source maps for files that contain emojis.
This is done by updating "deno_ast" to "0.14.1" for the case
of "--no-check" flag (ie using SWC emit) and by overriding
TSC's default base64 encoder (which turned out to be buggy)
for the type checking case.
This flag disables loading of configuration file, ie. it will not be
automatically discovered and loaded. Of course this flag conflicts
with "--config" flag and they cannot be used together.
This commit adds better reporting of uncaught errors
in top level scope of testing files. This change affects
both console runner as well as LSP runner.
Calling `worker.terminate()` used to kill the worker's isolate and
then block until the worker's thread finished. This blocks the calling
thread if the worker's event loop was blocked in a sync op (as with
`Deno.sleepSync`), which wasn't realized at the time, but since the
worker's isolate was killed at that moment, it would not block the
calling thread if the worker was in a JS endless loop.
However, in #12831, in order to work around a V8 bug, worker
termination was changed to first set a signal to let the worker event
loop know that termination has been requested, and only kill the
isolate if the event loop has not finished after 2 seconds. However,
this change kept the blocking, which meant that JS endless loops in
the worker now blocked the parent for 2 seconds.
As it turns out, after #12831 it is fine to signal termination and
even kill the worker's isolate without waiting for the thread to
finish, so this change does that. However, that might leave the async
ops that receive messages and control data from the worker pending
after `worker.terminate()`, which leads to odd results from the op
sanitizer. Therefore, we set up a `CancelHandler` to cancel those ops
when the worker is terminated.
This commit:
- removes "fmt_errors::PrettyJsError" in favor of "format_js_error" fn
- removes "deno_core::JsError::create" and
"deno_core::RuntimeOptions::js_error_create_fn"
- adds new option to "deno_runtime::ops::worker_host::init"
stream shutdown wasn't happening correctly (moved it to call op_http_shutdown) & extra zeroed bytes were being sent for when body length not a multiple of 64*1024
This commit changes "deno bench" subcommand, by updating
the "Deno.bench" API as follows:
- remove "Deno.BenchDefinition.n"
- remove "Deno.BenchDefintion.warmup"
- add "Deno.BenchDefinition.group"
- add "Deno.BenchDefintion.baseline"
This is done because bench cases are no longer run fixed amount
of iterations, but instead they are run until there is difference between
subsequent runs that is statistically insiginificant.
Additionally, console reporter was rewritten completely, to looks
similar to "hyperfine" reporter.
This commit adds support for "--eval-file" in "deno repl" subcommand.
This flag can be used to pass paths or URLs to files, that will be executed
on REPL startup. All files will be executed in the same context as the REPL
(ie. as "plain old scripts", not ES modules), sharing the global scope.
This feature allows to implement custom REPLs on top of Deno's REPL.
This commit changes "deno test" to filter out stack frames if it is beneficial to the user.
This is the case when there are stack frames coming from "internal" code
below frames coming from user code.

This commit fixes and edge case, where testing/benching code could pledge new
permission set before restoring the previous pledge.
Appropriate panics were added and tests that assert that process is killed
in case of "recursive pledge".
This commit rewrites test runner to send structured error data from JavaScript
to Rust instead of passing strings. This will allow to customize display of errors
in test report (which will be addressed in follow up commits).
This commit adds "aggregated" field to "deno_core::JsError" that stores
instances of "JsError" recursively to properly handle "AggregateError"
formatting. Appropriate logics was added to "PrettyJsError" and
"console" API to format AggregateErrors.

The following transformations gradually faced by "JsError" have all been
moved up front to "JsError::from_v8_exception()":
- finding the first non-"deno:" source line;
- moving "JsError::script_resource_name" etc. into the first error stack
in case of syntax errors;
- source mapping "JsError::script_resource_name" etc. when wrapping
the error even though the frame locations are source mapped earlier;
- removing "JsError::{script_resource_name,line_number,start_column,end_column}"
entirely in favour of "js_error.frames.get(0)".
We also no longer pass a js-side callback to "core/02_error.js" from cli.
I avoided doing this on previous occasions because the source map lookups
were in an awkward place.
This commit changes "deno test" to better denote user output coming
from test cases.
This is done by printing "---- output ----" and "---- output end ----"
markers if an output is produced. The output from "console" and
"Deno.core.print" is captured, as well as direct writes to "Deno.stdout"
and "Deno.stderr".
To achieve that new APIs were added to "deno_core" crate, that allow
to replace an existing resource with a different one (while keeping resource
ids intact). Resources for stdout and stderr are replaced by pipes.

Following changes were done in this commit:
- remove "test" prefix before each test
- use gray color for "running N tests from ..." prompt
- use relative path or remote URL instead of full URL in "running N tests from ..." prompt
- in "failures" section, add file path/remote URL before the test name

This commit adds new "deno check" subcommand.
Currently it is an alias for "deno cache" with the difference that remote
modules don't emit TS diagnostics by default.
Prints warning for "deno run" subcommand if "--check" flag is not present
and there's no "--no-check" flag. Adds "DENO_FUTURE_CHECK" env
variable that allows to opt into new behavior now.
This commit adds following fields to "Deno.TestContext" interface:
- name
- origin
- parent
These are prerequisites for supporting snapshot functionality in
"std/testing".
`handleWasmStreaming` is the function that provides the binding with
the `fetch` API needed for `WebAssembly.instantiateStreaming()` and
`WebAssembly.compileStreaming()`. When I implemented it in #11200, I
thought V8 was calling these functions with the argument of the
`WebAssembly` streaming functions, without doing any resolving, and so
`handleWasmStreaming` awaits for the parameter to resolve. However,
as discovered in
https://github.com/denoland/deno/issues/13917#issuecomment-1065805565,
V8 does in fact resolve the parameter if it's a promise (and handles
rejections arising from that).
This change removes the `async` IIFE inside `handleWasmStreaming`,
letting initial errors be handled synchronously (which will however
not throw synchronously from the `WebAssembly` namespace functions).
Awaiting is still necessary for reading the bytes of the response,
though, and so there is an `async` IIFE for that.
When an exception is thrown during the processing of streaming WebAssembly,
`op_wasm_streaming_abort` is called. This op calls into V8, which synchronously
rejects the promise and calls into the promise rejection handler, if applicable.
But calling an op borrows the isolate's `JsRuntimeState` for the duration of the
op, which means it is borrowed when V8 calls into `promise_reject_callback`,
which tries to borrow it again, panicking.
This change changes `op_wasm_streaming_abort` from an op to a binding
(`Deno.core.abortWasmStreaming`). Although that binding must borrow the
`JsRuntimeState` in order to access the `WasmStreamingResource` stored in the
`OpTable`, it also takes ownership of that `WasmStreamingResource` instance,
which means it can drop any borrows of the `JsRuntimeState` before calling into
V8.
This commit adds "Deno.upgradeHttp" API, which
allows to "hijack" connection and switch protocols, to eg.
implement WebSocket required for Node compat.

In the implementation of structured serialization in
`Deno.core.serialize`, whenever there is a serialization error, an
exception will be thrown with the message "Failed to serialize
response", even though V8 provides a message to use in such cases.
This change instead throws an exception with the V8-provided message,
if there is one.
This commit adds "deno bench" subcommand and "Deno.bench()"
API that allows to register bench cases.
The API is modelled after "Deno.test()" and "deno test" subcommand.
Currently the output is rudimentary and bench cases and not
subject to "ops" and "resource" sanitizers.

This commit fixes CJS/ESM interop in compat mode for dynamically
imported modules.
"ProcState::prepare_module_load" was changed to accept a list
of "graph roots" without associated "module kind". That module kind
was always hardcoded to "ESM" which is not true for CJS/ESM interop -
a CommonJs module might be imported using "import()" function. In
such case the root of the graph should have "CommonJs" module kind
instead of "ESM".
This commit adds CJS/ESM interoperability when running in --compat mode.
Before executing files, they are analyzed and all CommonJS modules are
transformed on the fly to a ES modules. This is done by utilizing analyze_cjs()
functionality from deno_ast. After discovering exports and reexports, an ES
module is rendered and saved in memory for later use.
There's a caveat that all files ending with ".js" extension are considered as
CommonJS modules (unless there's a related "package.json" with "type": "module").
This commit adds "--trace-ops" flag to "deno test" subcommand.
This flag enables saving of stack traces for async ops, that before were always
saved. While the feature proved to be very useful it comes with a significant performance
hit, it's caused by excessive source mapping of stack frames.
This commit improves the error messages for the `deno test` async op
sanitizer. It does this in two ways:
- it uses handwritten error messages for each op that could be leaking
- it includes traces showing where each op was started
This "async op tracing" functionality is a new feature in deno_core.
It likely has a significant performance impact, which is why it is only
enabled in tests.
This commit adds `readable` and `writable` properties to `Deno.File` and
`Deno.Conn`. This makes it very simple to use files and network sockets
with fetch or the native HTTP server.
Adds another callback to WebWorkerOptions that allows to execute
some modules before actual worker code executes. This allows to set up Node
global using std/node.
This commit makes the errors produced from the resource sanitizer much
more human readable. It does this by using real words rather than our
"resource names" when referring to resources, and by giving helpful
hints on how to clean up each of the resources.
This commit fixes an error when user deletes "window" global JS
variable. Instead of relying on "window" or "globalThis" to dispatch
"load" and "unload" events, we are default to global scope of the
worker.
V8 has supported `Intl.ListFormat` since version 7.2, but TypeScript doesn't
have typings for it yet. This PR manually adds those typings, copying them from
microsoft/TypeScript#47254.
Deno's module loader currently strips a shebang if a module file
starts with one. However, this is no longer necessary, since there is
a stage-3 TC39 that adds support for shebangs (or "hashbangs") to the
language (https://github.com/tc39/proposal-hashbang), and V8, `tsc`
and `swc` all support it.
Furthermore, stripping shebangs causes a correctness bug with JSON
modules, since a JSON file with a shebang should not parse as a JSON
module, yet it does with this stripping. This change fixes this.
This commit adds lint and fmt ignore directives to bundled
code as well as a comment stating that the code was bundled
and shouldn't be edited manually.
Covered ranges were not merged and thus it appeared that some lines
might be uncovered. To fix this I used "v8-coverage" that takes care
of merging the ranges properly. With this change, coverage collected
from a file by multiple entrypoints is now correctly calculated.
I ended up forking https://github.com/demurgos/v8-coverage and adding
"cli/tools/coverage/merge.rs" and "cli/tools/coverage/range_tree.rs".
This commit changes "deno coverage" command not to type check.
Instead of relying on infrastructure for module loading in "deno run";
the code now directly reaches into cache for original and transpiled
sources. In case sources are not available the error is returned to the
user, suggesting to first run "deno test --coverage" command.
This commit changes flow in inspector code to no longer require
"Runtime.runIfWaitingForDebugger" message to complete a handshake.
Even though clients like Chrome DevTools always send this message on startup,
it is against the protocol to require this message to start an inspector
session.
Instead "Runtime.runIfWaitingForDebugger" is required only when running with
"--inspect-brk" flag, which matches behavior of Node.js.
This commit fixes prompts printed to the terminal when
running with "--inspect" or "--inspect-brk" flags.
When debugger disconnects error is no longer printed as
users don't care about the reason debugger did disconnect.
A message suggesting to go to "chrome://inspect" is printed
if debugger is active.
Additionally and information that process is waiting for
debugger to connect is printed if running with "--inspect-brk"
flag.
This commit fixes inspector integration with "deno test" subcommand
by waiting for inspector sessions to connect if "--inspect-brk" flag
is passed.

This commit adds proper support for import assertions and JSON modules.
Implementation of "core/modules.rs" was changed to account for multiple possible
module types, instead of always assuming that the code is an "ES module". In
effect "ModuleMap" now has knowledge about each modules' type (stored via
"ModuleType" enum). Module loading pipeline now stores information about
expected module type for each request and validates that expected type matches
discovered module type based on file's "MediaType".
Relevant tests were added to "core/modules.rs" and integration tests,
additionally multiple WPT tests were enabled.
There are still some rough edges in the implementation and not all WPT were
enabled, due to:
a) unclear BOM handling in source code by "FileFetcher"
b) design limitation of Deno's "FileFetcher" that doesn't download the same
module multiple times in a single run

std/http/server knows how to handle "Listener has been closed"
exceptions but not "operation canceled" errors.
Make "unix" listen sockets throw the same exception as "tcp" listen
sockets when the socket is closed and has a pending accept operation.
There is still a discrepancy when multiple accept requests are posted
but that's probably a less visible issue and something for another day.
Fixes #13033

Fixes "op_set_exit_code" by sharing a single "Arc" between
all workers (via "op state") instead of having a "global" value stored in
"deno_runtime" crate. As a consequence setting an exit code is always
scoped to a tree of workers, instead of being overridable if there are
multiple worker tree (like in "deno test --jobs" subcommand).
Refactored "cli/main.rs" functions to return "Result<i32, AnyError>" instead
of "Result<(), AnyError>" so they can return exit code.
This change also makes the timers implementation closer to the spec, and
sets up the stage to implement AbortSignal.timeout() (whatwg/dom#1032).
Fixes #8965
Fixes #10974
Fixes #11398
Although not easy to replicate in the wild, the `deno test` op sanitizer
can fail when there are intervals that started before a test runs, since
the op sanitizer can end up running in the time between the timer op for
an interval's run resolves and the op for the next run starts.
This change fixes that by adding a new macrotask callback that will run
after the timer macrotask queue has drained. This ensures that there is
a timer op if there are any timers which are unresolved by the time the
op sanitizer runs.
Due to a bug in V8, terminating an isolate while a module with top-level
await is being evaluated would crash the process. This change makes it
so calling `worker.terminate()` will signal the worker to terminate at
the next iteration of the event loop, and it schedules a proper
termination of the worker's isolate after 2 seconds.

Set the exit code to use if none is provided to Deno.exit(), or when
Deno exits naturally.
Needed for process.exitCode Node compat. Paves the way for #12888.
Fetching of local files, added in #12545, returns a response with no
headers, including the `Content-Type` header. This currently makes it
not work with the WebAssembly streaming APIs, which require the response
to have a content type of `application/wasm`.
Since the only way to obtain a `Response` object with a non-empty `url`
field is via `fetch()`, this change changes the content type requirement
to only apply to responses whose url has the `file:` scheme.
Reduce the number of iterations from 1,024 to 128.
On my big bruiser of a desktop machine it already takes up close to a
minute to complete when nothing else is running so no way it's going to
finish in the allotted time on the CI.
The fact that the test used to pass may be indicative of a performance
regression somewhere but it's not clear to me when or where that would
have been introduced.
Fixes #12887.
This commit introduces "ProcState::maybe_resolver" field, which
stores a single instance of resolver for the whole lifetime of the
process, instead of creating these resolvers for each creation
of module graph. As a result, this resolver can be used in fallback
case where graph is not constructed (REPL, loading modules using
"require") unifying resolution logic.
This commit speeds up compat tests by using local copy of "deno_std"
instead of downloading it from https://deno.land for each test.
Additionally type checking is skipped.
This allows resources to be "streams" by implementing read/write/shutdown. These streams are implicit since their nature (read/write/duplex) isn't known until called, but we could easily add another method to explicitly tag resources as streams.
`op_read/op_write/op_shutdown` are now builtin ops provided by `deno_core`
Note: this current implementation is simple & straightforward but it results in an additional alloc per read/write call
Closes #12556
This commit changes formatting of elapsed time in test
runner output.
Instead of "XXXms", reporter outputs one of:
- "XXXms" for <1000ms
- "XXs" for <60s
- "XXXmYYs" for >=60s
This commit integrates import map and "classic" resolutions in
the "--compat" mode when using ES modules; in effect
"http:", "https:" and "blob:" imports now work in compat mode.
The algorithm works as follows:
1. If there's an import map, try to resolve using it and if succeeded
return the specifier
2. Try to resolve using "Node ESM resolution", and if succeeded return
the specifier
3. Fall back to regular ESM resolution
Closes #11826
**BREAKING CHANGE** this behaviour was disable when introduced in Deno 1.14/TypeScript 4.4. It will highlight code that unsafely handles variables that are caught, and will cause type errors in unsafe code.
Closes #11882
BREAKING CHANGE: Previously when `--location` was set, the unique storage key was derived from the the URL of the location instead of just the origin. This change correctly uses just the origin. This may cause previously persisted storage to change its key and data to not be available with the same location as before.
A `handshake()` method was added that returns when the TLS handshake is
complete. The `TlsListener` and `TlsConn` interfaces were added to
accomodate this new method.
Closes: #11759.
`fetch()` and client-side websocket used to support HTTP/2, but this
regressed in #11491. This patch reenables it by explicitly adding `h2`
and `http/1.1` to the list of ALPN protocols on the HTTP and websocket
clients.
A bug was fixed that could cause a hang when a method was
called on a TlsConn object that had thrown an exception earlier.
Additionally, a bug was fixed that caused TlsConn.write() to not
completely flush large buffers (>64kB) to the socket.
The public `TlsConn.handshake()` API is scheduled for inclusion in the

This commit adds CJS and ESM Node resolvers to the "--compat" mode.
The functionality is spread across "cli/compat" module and Node compatibility
layer in "deno_std/node"; this stems from the fact that ES module resolution
can only be implemented in Rust as it needs to directly integrated with
"deno_core"; however "deno_std/node" already provided CJS module resolution.
Currently this resolution is only active when running a files using
"deno run --compat --unstable <filename>", and is not available in other
subcommands, which will be changed in follow up commits.
Returns empty values in case of errors, source lines are non-essential anyway. These errors can happen e.g. when source files change at runtime. A warning is also printed to help us track when it happens in unexpected cases besides this.
Currently all async ops are polled lazily, which means that op
initialization code is postponed until control is yielded to the event
loop. This has some weird consequences, e.g.
```js
let listener = Deno.listen(...);
let conn_promise = listener.accept();
listener.close();
// `BadResource` is thrown. A reasonable error would be `Interrupted`.
let conn = await conn_promise;
```
JavaScript promises are expected to be eagerly evaluated. This patch
makes ops actually do that.
On OS X, the watcher sometimes witnesses the creation of it's own root
directory. Creating that directory using a sync op instead of an async
op sidesteps the issue.
This commit fixes problem with LSP where diagnostics coming
from "deno lint" don't respect configuration file.
LSP was changed to store "Option<ConfigFile>", "Option<LintConfig>"
and "Option<FmtConfig>" on "Inner"; as well as storing "Option<LintConfig>"
and "Option<FmtConfig>" on "StateSnapshot".

`Window`'s `self` property and `DedicatedWorkerGlobalScope`'s `name`
property are defined as Web IDL read-only attributes with the
`[Replaceable]` extended attribute, meaning that their setter will
redefine the property as a data property with the set value, rather than
changing some internal state. Deno currently defines them as read-only
data properties instead.
Given that Web IDL requires all attributes to be accessor properties
rather than data properties, but Deno exposes almost all of those
properties as either read-only or writable data properties, it makes
sense to expose `[Replaceable]` properties as writable as well – as is
already the case with `WindowOrWorkerGlobalScope`'s `performance`
property.
GET/HEAD requests can't have bodies according to `fetch` spec. This
commit changes the HTTP server to hide request bodies for requests with
GET or HEAD methods.
This commit annotates errors returned from FS Deno APIs to include
paths that were passed to the API calls.

WebAssembly modules compiled through `WebAssembly.compile()` and similar
non-streaming APIs don't have a URL associated to them, because they
have been compiled from a buffer source. In stack traces, V8 will use
a URL such as `wasm://wasm/d1c677ea`, with a hash of the module.
However, wasm modules compiled through streaming APIs, like
`WebAssembly.compileStreaming()`, do have a known URL, which can be
obtained from the `Response` object passed into the streaming APIs. And
as per the developer-facing display conventions in the WebAssembly
Web API spec, this URL should be used in stack traces. This change
implements that.
This commit adds automatic injection of Node globals when "--compat" flag
is present.
This is done by executing "https://deno.land/std/node/global.ts" as a "side module",
before main module is executed.
This commit makes "--compat" required to be used with "--unstable" flag, as some
of Node globals require unstable Deno APIs.
This commit adds "--compat" flag. When the flag is passed a set of mappings for
built-in Node modules is injected into the import map. If user doesn't
explicitly provide an import map (using "--import-map" flag) then a map is
created on the fly. If there are already existing mappings in import map that
would clash with built-in Node modules a set of diagnostics is printed to the
terminal with suggestions how to proceed.
This adds support for using in memory CA certificates for
`Deno.startTLS`, `Deno.connectTLS` and `Deno.createHttpClient`.
`certFile` is deprecated in `startTls` and `connectTls`, and removed
from `Deno.createHttpClient`.
Our oneshot receiver in `HyperService::call` would unwrap and panic, the `.await` on the oneshot receiver happens when the sender is dropped.
The sender is dropped in `op_http_response` because:
1. We take `ResponseSenderResource`
2. Then get `ConnResource` and early exit on failure (conn already closed)
3. The taken sender then gets dropped in this early exit before any response is sent over the channel
Fallbacking to returning a dummy response to hyper seems to be a fine quickfix
This panic could happen in the following cases:
- A non-fatal error being thrown from a worker, that doesn't terminate
the worker's execution, but propagates to the main thread without
being handled, and makes the main thread terminate.
- A nested worker being alive while its parent worker gets terminated.
- A race condition if the main event loop terminates the worker as part
of its last task, but the worker doesn't fully terminate before the
main event loop stops running.
This panic happens because a worker's event loop should have pending ops
as long as the worker isn't closed or terminated – but if an event loop
finishes running while it has living workers, its associated
`WorkerThread` structs will be dropped, closing the channels that keep
those ops pending.
This change adds a `Drop` implementation to `WorkerThread`, which
terminates the worker without waiting for a response. This fixes the
panic, and makes it so nested workers are automatically terminated once
any of their ancestors is closed or terminated.
This change also refactors a worker's termination code into a
`WorkerThread::terminate()` method.
Closes #11342.

This commit adds support for configuration file for "deno fmt"
subcommand. It is also respected by LSP when formatting
files.
Example configuration:
{
"fmt": {
"files": {
"include": ["src/"],
"exclude": ["src/testdata/"]
},
"options": {
"useTabs": true,
"lineWidth": 80,
"indentWidth": 4,
"singleQuote": true,
"textWrap": "preserve"
}
}
}
This adds support for the URLPattern API.
The API is added in --unstable only, as it has not yet shipped in any
browser. It is targeted for shipping in Chrome 95.
Spec: https://wicg.github.io/urlpattern/
Co-authored-by: crowlKats < crowlkats@toaxl.com >
When `worker.terminate()` is called, the spec requires that the
corresponding port message queue is emptied, so no messages can be
received after the call, even if they were sent from the worker before
it was terminated.
The spec doesn't require this of `self.close()`, and since Deno uses
different channels to send messages and to notify that the worker was
closed, messages might still arrive after the worker is known to be
closed, which are currently being dropped. This change fixes that.
The fix involves two parts: one on the JS side and one on the Rust side.
The JS side was using the `#terminated` flag to keep track of whether
the worker is known to be closed, without distinguishing whether further
messages should be dropped or not. This PR changes that flag to an
enum `#state`, which can be one of `"RUNNING"`, `"CLOSED"` or
`"TERMINATED"`.
The Rust side was removing the `WorkerThread` struct from the workers
table when a close control was received, regardless of whether there
were any messages left to read, which made any subsequent calls to
`op_host_recv_message` to return `Ok(None)`, as if there were no more
mesasges. This change instead waits for both a close control and for
the message channel's sender to be closed before the worker thread is
removed from the table.
This commit adds support for following flags in deno lint subcommand:
--config - allows to load configuration file and parses "lint" object
--rules-tags=<tags> - allows specifying which set of tagged rules should be run
--rules-include=<rules> - allow specifying which rules should be run
--rules-exclude=<rules> - allow specifying which rules should not be run
This commit merges the two vectors of specifiers into a single one introducing
the concept of a "TestMode" which is a tri-state enum specifying how a specifier
is to be tested (as documentation, as an executable module or as both).
This is determined during the collection phase and determines how a specifier
will be executed based on how the specifier was collected (directly or not) and
if it has an eligible media_type when fetched.
For example "deno test README.md" is marked as documentation because, while it
is a direct inclusion it is not an executable media type therefore will only
have the fenced code blocks that can be parsed from it tested.
Classic worker scripts are now executed in the context of a Tokio
runtime. This does mean we can not spawn more tokio runtimes in
"op_worker_sync_fetch". We instead spawn a new thread there, that can
create a new Tokio runtime that we can use to block the worker thread.
The streaming WASM support code inspects the Response object's
Content-Type header but if that was missing, it failed with a fairly
inscrutable "String.prototype.toLowerCase called on null or undefined"
exception. Now it raises a more legible "Invalid WebAssembly content
type" exception.
This commit adds a test case for "Http: connection closed before
message completed" error as well as fixing an edge with resource
leak when the error is raised.
This commit adds "--unsafely-treat-insecure-origin-as-secure" flag
that allows to disable SSL verification for all domains, or specific
domains if they were passed as an argument to the flag.

This commit adds "DENO_TLS_CA_STORE" env variable to support
optionally loading certificates from the users local certificate store.
This will allow them to successfully connect via tls with corporate
and self signed certs provided they have them installed in their keystore.
It also allows them to deal with revoked certs by simply updating
their keystore without having to upgrade Deno.
Currently supported values are "mozilla", "system" or empty value.
This commit removes implementation of "native plugins" and replaces
it with FFI API.
Effectively "Deno.openPlugin" API was replaced with "Deno.dlopen" API.
This commit adds support for specifying threshold in the "--fail-fast"
flag for "deno test" subcommand. Previously using "--fail-fast" stopped
running the test suite after first failure and with this change users
may specify number of failed tests that will cause the suite to be interrupted.

This commit adds "--terse" flag to "deno test" that makes testing reporter
output one character per test case instead of one line per case.
This is an unstable feature.
The WebAssembly streaming APIs used to be enabled, but used to take
buffer sources as their first argument (see #6154 and #7259). This
change re-enables them, requiring a Promise<Response> instead, as well as
enabling asynchronous compilation of WebAssembly modules.
This commits moves implementation of net related APIs available on "Deno"
namespace to "deno_net" extension.
Following APIs were moved:
- Deno.listen()
- Deno.connect()
- Deno.listenTls()
- Deno.serveHttp()
- Deno.shutdown()
- Deno.resolveDns()
- Deno.listenDatagram()
- Deno.startTls()
- Deno.Conn
- Deno.Listener
- Deno.DatagramConn
This commit adds support for piping console messages to inspector.
This is done by "wrapping" Deno's console implementation with default
console provided by V8 by the means of "Deno.core.callConsole" binding.
Effectively each call to "console.*" methods calls a method on Deno's
console and V8's console.
This PR refactors the usages of delay utility in js unit testing. The same
utiliy is defined in several places with different names. This PR replaces those
usages with the one provided in std/async/delay.ts to improve the readability
and consistency of test code.
This commit adds new options to unstable "Deno.createHttpClient" API.
"proxy" and "basicAuth" options were added that allow to use custom proxy
when client instance is passed to "fetch" API.
This commit renames "JsRuntime::execute" to "JsRuntime::execute_script". Additionally
same renames were applied to methods on "deno_runtime::Worker" and
"deno_runtime::WebWorker".
A new macro was added to "deno_core" called "located_script_name" which
returns the name of Rust file alongside line no and col no of that call site.
This macro is useful in combination with "JsRuntime::execute_script"
and allows to provide accurate place where "one-off" JavaScript scripts
are executed for internal runtime functions.

This commit changes module loading implementation in "deno_core"
to call "ModuleLoader::prepare" hook only once per entry point.
This is done to avoid multiple type checking of the same code
in case of duplicated dynamic imports.
Relevant code in "cli/module_graph.rs" was updated as well.
This commit updates type declarations for Worker to accept specifiers
as either strings or URL, bringing it in line with TypeScript
declarations and browser behavior.
This commit changes "op_http_response_write" to first send response chunk
and then poll the underlying HTTP connection.
Previously after writing a chunk of response HTTP connection wasn't polled
and thus data wasn't written to the socket until after next op interacting
with the connection.
Waiting on next request in Deno.serveHttp() API hanged
when responses were using ReadableStream. This was caused
by op_http_request_next op that was never woken after
response was fully written. This commit adds waker field to
DenoService which is called after response is finished.
This commit removes all JS based text encoding / text decoding. Instead
encoding now happens in Rust via encoding_rs (already in tree). This
implementation retains stream support, but adds the last missing
encodings. We are incredibly close to 100% WPT on text encoding now.
This should reduce our baseline heap by quite a bit.
This commit adds "CancelHandle" to "ConnResource" and changes
"op_http_next_request" to await for the cancel signal. In turn
when async iterating over "Deno.HttpConn" the iterator breaks
upon closing of the resource.
Replaces the file-backed provider by an in-memory one because proper
file locking is a hard problem that detracts from the proof of concept.
Teach the WPT runner how to extract tests from .html files because all
the relevant tests in test_util/wpt/webmessaging/broadcastchannel are
inside basics.html and interface.html.
In #9118, TLS streams were split into a "read half" and a "write half"
using tokio::io::split() to allow concurrent Conn#read() and
Conn#write() calls without one blocking the other. However, this
introduced a bug: outgoing data gets discarded when the TLS stream is
gracefully closed, because the read half is closed too early, before all
TLS control data has been received.
Fixes: #9692
Fixes: #10049
Fixes: #10296

This commit implements file watching for deno test.
When a file is changed, only the test modules which
use it as a dependency are rerun.
This is accomplished by reworking the file watching infrastructure
to pass the paths which have changed to the resolver, and then
constructing a module graph for each test module to check if it
contains any changed files.
Fixes a pesky bug in the fetch implementation where if the init part is
specified in `fetch` instead of the `Request` constructor, the
fillHeaders function receives two references to the same object, causing
it to append to the same list being iterated over.
This commit adds support for running test in parallel.
Entire test runner functionality has been rewritten
from JavaScript to Rust and a set of ops was added to support reporting in Rust.
A new "--jobs" flag was added to "deno test" that allows to configure
how many threads will be used. When given no value it defaults to 2.
Extensions allow declarative extensions to "JsRuntime" (ops, state, JS or middleware).
This allows for:
- `op_crates` to be plug-and-play & self-contained, reducing complexity leaked to consumers
- op middleware (like metrics_op) to be opt-in and for new middleware (unstable, tracing,...)
- `MainWorker` and `WebWorker` to be composable, allowing users to extend workers with their ops whilst benefiting from the other infrastructure (inspector, etc...)
In short extensions improve deno's modularity, reducing complexity and leaky abstractions for embedders and the internal codebase.
General cleanup of module loading code, tried to reduce indentation in various methods
on "JsRuntime" to improve readability.
Added "JsRuntime::handle_scope" helper function, which returns a "v8::HandleScope".
This was done to reduce a code pattern that happens all over the "deno_core".
Additionally if event loop hangs during loading of dynamic modules a list of
currently pending dynamic imports is printed.
`InvalidDNSNameError` is thrown when a string is not a valid hostname,
e.g. it contains invalid characters, or starts with a numeric digit. It
does not involve a (failed) DNS lookup.
denort is an optimization to "deno compile" to produce slightly smaller
output. It's a decent idea, but causes a lot of negative side-effects:
- Deno's link time is a source of constant agony both locally and in CI,
denort doubles link time.
- The release process is a long and arduous undertaking with many manual
steps. denort necessitates an additional manual zip + upload from M1
apple computers.
- The "deno compile" interface is complicated with the "--lite" option.
This is confusing for uses ("why wouldn't you want lite?").
The benefits of this feature do not outweigh the negatives. We must find
a different approach to optimizing "deno compile" output.
This commits adds adds "permissions" option to the test definitions
which allows tests to run with different permission sets than
the process's permission.
The change will only be in effect within the test function, once the
test has completed the original process permission set is restored.
Test permissions cannot exceed the process's permission.
You can only narrow or drop permissions, failure to acquire a
permission results in an error being thrown and the test case will fail.
This commit aligns the `fetch` API and the `Request` / `Response`
classes belonging to it to the spec. This commit enables all the
relevant `fetch` WPT tests. Spec compliance is now at around 90%.
Performance is essentially identical now (within 1% of 1.9.0).
This commit fixes the URL returned from `request.url` in the HTTP server
to be fully qualified. This previously existed, but was removed and
accidentially not readded during optimizations of the HTTP ops.
Returning a non fully qualified URL from `Request#url` is not spec
compliant.
The panic was caused by the lack of an error class mapping for
futures::channel::TrySendError, but it shouldn't have been throwing an error in
the first place - when a worker has terminated, postMessage should just return.
The issue was that the termination message hadn't yet been recieved, so it was
carrying on with trying to send the message. This adds another check on the Rust
side for if the channel is closed, and if it is the worker is treated as
terminated.
This commit aligns `Headers` to spec. It also removes the now unused
03_dom_iterable.js file. We now pass all relevant `Headers` WPT. We do
not implement any sort of header filtering, as we are a server side
runtime.
This is likely not the most efficient implementation of `Headers` yet.
It is however spec compliant. Once all the APIs in the `HTTP` hot loop
are correct we can start optimizing them. It is likely that this commit
reduces bench throughput temporarily.
This commit adds allowlist support to `--allow-run` flag.
Additionally `Deno.permissions.query()` allows to query for specific
programs within allowlist.
This commit adds blob URL support. Blob URLs are stored in a process
global storage, that can be accessed from all workers, and the module
loader. Blob URLs can be created using `URL.createObjectURL` and revoked
using `URL.revokeObjectURL`.
This commit does not add support for `fetch`ing blob URLs. This will be
added in a follow up commit.
This commit marks the `Deno.Buffer` / `Deno.readAll` /
`Deno.readAllSync` / `Deno.writeAll` / `Deno.writeAllSync` utils as
deprecated, and schedules them for removal in Deno 2.0. These
utilities are implemented in pure JS, so should not be part of the
Deno namespace.
These utilities are now available in std/io/buffer and std/io/util:
https://github.com/denoland/deno_std/pull/808.
This additionallty removes all internal dependance on Deno.Buffer.
- Improves op performance.
- Handle op-metadata (errors, promise IDs) explicitly in the op-layer vs
per op-encoding (aka: out-of-payload).
- Remove shared queue & custom "asyncHandlers", all async values are
returned in batches via js_recv_cb.
- The op-layer should be thought of as simple function calls with little
indirection or translation besides the conceptually straightforward
serde_v8 bijections.
- Preserve concepts of json/bin/min as semantic groups of their
inputs/outputs instead of their op-encoding strategy, preserving these
groups will also facilitate partial transitions over to v8 Fast API for the
"min" and "bin" groups
This commit moves implementation of bin ops to "deno_core" crates
as well as unifying logic between bin ops and json ops to reuse
as much code as possible (both in Rust and JavaScript).
Change `Console.#printFunc` to pass a log level as the second argument
(0 = debug, 3 = error), instead of a boolean for `isErr`. This does not
change the Deno runtime behaviour at all.
This commit rewrites "dispatch_minimal" into "dispatch_buffer".
It's part of an effort to unify JS interface for ops for both json
and minimal (buffer) ops.
Before this commit "minimal ops" could be either sync or async
depending on the return type from the op, but this commit changes
it to have separate signatures for sync and async ops (just like
in case of json ops).
This commit rewrites implementation of "JsRuntime::mod_evaluate".
Event loop is no longer polled automatically and users must manually
drive event loop forward after calling "mod_evaluate".

This commit changes formatting of JS errors; by not showing
source lines for internal code. Where possible, instead using
the top stack frame associated with user code i.e. the first
location that is colourful and not a "deno:" URL.
This commit adds support for type definitions in "deno doc";
with this change "deno doc" is able to leverage the same directives
as TS compiler.

This commit adds a new subcommand called "coverage"
which can generate code coverage reports to stdout in
multiple formats from code coverage profiles collected to disk.
Currently this supports outputting a pretty printed diff and
the lcov format for interoperability with third-party services and tools.
Code coverage is still collected via other subcommands
that run and collect code coverage such as
"deno test --coverage=<directory>" but that command no
longer prints a pretty printed report at the end of a test
run with coverage collection enabled.
The restrictions on which files that can be reported on has
also been relaxed and are fully controllable with the include
and exclude regular expression flags on the coverage subcommand.

This commit removes redundant "--reload" args because "util::deno_cmd"
recreates "DENO_DIR".
This commit also fixes ta_reload in integration tests to actually test reload.
This adds an exit sanitizer to ensure that code being tested or
dependencies of that code can't accidentally call "Deno.exit"
leading to partial test runs and false results.
This commit rewrites "JsRuntime::poll" function to fix a corner case that
might caused "overflown_response" to be overwritten by other overflown response.
The logic has been changed to allow returning multiple overflown response
alongside responses from shared queue.
This PR deprecates the "--ts"/"-T" flag of "deno eval" (which will later be removed in 2.0)
and introduces "--ext" which is used by "deno fmt" for content type selection.
This is to ensure we have a single flag that can be used across subcommands
to select the language (JS/TS).
Currently if WebSocket is closed without code, it will error
while on Chrome it would close with code 1005 instead.

This commit adds support for formatting JSON and JSONC
in "deno fmt".
New values "json" and "jsonc" are added to "--ext" flag for
standard input processing.
This commit adds support for loading import maps from URLs,
both remote and local.
This feature is supported in CLI flag as well as in runtime
compiler API.
This PR makes json_op_sync/async generic to all Deserialize/Serialize types
instead of the loosely-typed serde_json::Value. Since serde_json::Value
implements Deserialize/Serialize, very little existing code needs to be updated,
however as json_op_sync/async are now generic, type inference is broken in some
cases (see cli/build.rs:146). I've found this reduces a good bit of boilerplate,
as seen in the updated deno_core examples.
This change may also reduce serialization and deserialization overhead as serde
has a better idea of what types it is working with. I am currently working on
benchmarks to confirm this and I will update this PR with my findings.
When we migrated away from all the locks, there was a regression that
was not caught immediately. The tsc::get_asset() would attempt to modify
the snapshot, but the problem was that the snapshot was a .clone() of
the inner language server's assets, which meant that modifications to
that where lost. When we then attempted to do a hover on those assets,
the inner language servers assets didn't have the retrieved asset, and
therefore would throw an error.
This removes the std folder from the tree.
Various parts of the tests are pretty tightly dependent
on std (47 direct imports and 75 indirect imports, not
counting the cli tests that use them as fixtures) so I've
added std as a submodule for now.
This commit reorganises cli/tests/integration_tests.rs.
All integration tests had been moved into integration module,
which allows to run only integration tests by "cargo test integration".
Additionally some tests were further grouped under nested modules
like "inspector", "file_watcher" or "repl".
This commits makes use of source maps and the original source
when printing lacking line coverage in the pretty printer.
Only the executable lines are checked as before (as non-executable
lines will always be ignored anyways). The lines then mapped to the
appropriate source line when a source map is present.
This commit adds support for formatting markdown files with "deno fmt".
Additionally "--ext={js|jsx|ts|tsx|md}" flag was added to "deno fmt"
that allows to specify file type when providing contents over stdio.
Previously, calling `Process#kill()` after the process had exited would
sometimes throw a `TypeError` on Windows. After this patch, it will
throw `NotFound` instead, just like other platforms.
This patch also fixes flakiness of the `runKillAfterStatus` test on
Windows.

This commit adds new option to "Worker" Web API that allows to
configure permissions.
New "Worker.deno.permissions" option can be used to define limited
permissions to the worker thread by either:
- inherit set of parent thread permissions
- use limited subset of parent thread permissions
- revoke all permissions (full sandbox)
In order to achieve this functionality "CliModuleLoader"
was modified to accept "initial permissions", which are used
for top module loading (ie. uses parent thread permission set
to load top level module of a worker).
Merging multiple runs isn't quite right because we
rely on a 0 count to signal that a block hasn't been called.
Other tools like c8 expect this to be true as-well so we
need to do our best to merge coverage files rather
than duplicating them.
The child process kept running and printing "hello" to stdout.
This commit also removes the dependency on reqwest and instead
switches to the re-export from the fetch crate.
Brings back commit 1a2e7741c3.
This commit adds back "/json/list" endpoint to
inspector server which was erroneously removed

Fix bug in regular expression and make the regular expression more
strict.
In a string passed to new RegExp(), '[\t\s]' is identical to '[ts]' and
not `/[\t\s]/`. For that, the backslash needs to be escaped in the
string. Futhermore, `\t` is the tab character and is included in the
special regexp value `\s` so is unnecessary.
That would reduce the RegExp to new RegExp(`^${value}\\s*;?`) but
there's no point in matching 0 or more space characters followed by 0 or
one semi-colons as that will match no matter what follows `value`.
To make it more strict, require one of space, semicolon, or
end-of-string after value.
Allowlist checking already uses hosts but for some reason
requests, revokes and the runtime permissions API use URLs.
- BREAKING(lib.deno.unstable.d.ts): Change
NetPermissionDescriptor::url to NetPermissionDescriptor::host
- fix(runtime/permissions): Don't add whole URLs to the
allowlist on request
- fix(runtime/permissions): Harden strength semantics:
({ name: "net", host: "127.0.0.1" } is stronger than
{ name: "net", host: "127.0.0.1:8000" }) for blocklisting
- refactor(runtime/permissions): Use tuples for hosts, make
the host optional in Permissions::{query_net, request_net, revoke_net}()
This commit rewrites "chown_test.ts" to use the GNU "id" command
instead of python. This won't work on Windows, but these tests aren't
currently run on Windows anyway.
Implementors of `deno_core::JsRuntime` might want to do additional actions
during each turn of event loop, eg. `deno_runtime::Worker` polls inspector,
`deno_runtime::WebWorker` receives/dispatches messages from/to worker host.
Previously `JsRuntime::mod_evaluate` was implemented in such fashion that it
only polled `JsRuntime`'s event loop. This behavior turned out to be wrong
in the example of `WebWorker` which couldn't receive/dispatch messages because
its implementation of event loop was never called.
This commit rewrites "mod_evaluate" to return a handle to receiver that resolves
when module's promise resolves. It is now implementors responsibility to poll
event loop after calling `mod_evaluate`.
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.
This commit does major refactor of "Worker" and "WebWorker",
in order to decouple them from "ProgramState" and "Flags".
The main points of interest are "create_main_worker()" and
"create_web_worker_callback()" functions which are responsible
for creating "Worker" and "WebWorker" in CLI context.
As a result it is now possible to factor out common "runtime"
functionality into a separate crate.
This commit adds "Deno.core.createPrepareStackTrace". This function
was moved from "cli/rt/40_error_stack.js" to unify handling of stack frames in core
(before this PR there was implicit dependency on logic in "core/error.rs::JsError").
Unfortunately formatting logic must still be duplicated in "cli/error.js::PrettyJsError"
to provide coloring, but currently there's no solution to this problem.
"createPrepareStackTrace" can accept a single argument; a function that takes
a location and provides source mapped location back.
