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 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).
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.

This commit adds following fields to "Deno.TestContext" interface:
- name
- origin
- parent
These are prerequisites for supporting snapshot functionality in
"std/testing".
Streamlines a common middleware pattern and provides foundations for avoiding variably sized v8::ExternalReferences & enabling fully monomorphic op callpaths
This commit adds "Deno.upgradeHttp" API, which
allows to "hijack" connection and switch protocols, to eg.
implement WebSocket required for Node compat.

Previously specifying permissions: {} was the same as specifying
permissions: "inherit". Now it will be the same as permissions: "none".
Not specifying any permissions (permissions: undefined) still means
permissions: "inherit".
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 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.
