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
