It has good intentions, but it is a really terrible user experience. As
such we shouldn't print this warning.

This commit adds support for "DENO_NO_PROMPT" env
variable, that can be used instead of "--no-prompt" flag
to completely disable permission prompts.

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.

pledge (#14306)
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.

`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.

`WebAssembly.instantiateStreaming` (#13925)
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.

Logs task name and associated script with additional args.
This is disabled if "--quiet/-q" flag is present.

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 changes "deno test" subcommand, to
always never prompt for permissions (ie. as if "deno test"
was run with "--no-prompt" flag).
|
|
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.
