This commit adds automatic expansion of "imports" field in "deno.json"
file.
If "npm:" or "jsr:" imports are encountered we automatically try to add
a "directory" remapping.
Previously users had to specify entries for both `foo` and `foo/` to be
able to import like
`import { symbol1 } from "foo";` and `import { symbol2 } from
"foo/some_file.js"`:
```
{
"imports": {
"foo": "npm:@foo/bar",
"foo/": "npm:/@foo/bar/",
}
```
With this change users can only add entry for `foo`:
```
{
"imports": {
"foo": "npm:@foo/bar",
}
```
The entry for `foo/` will be provided automatically.
Similarly if user provides "directory" remapping explicitly, we will not
overwrite it.
Removes weird "frame like" characters and simplifies the output:
```

This commit deprecates `window` global and adds deprecation
notice on each use of `window`.
We decided to proceed with removal of `window` global variable in Deno
2.0. There's a lot of code
in the wild that uses pattern like this:
```
if (typeof window !== "undefined) {
...
}
```
to check if the code is being run in browser. However, this check passes
fine in Deno and
most often libraries that do this check try to access some browser API
that is not available
in Deno, or use DOM APIs (which are also not available in Deno).
This situation has occurred multiple times already
and it's unfeasible to expect the whole ecosystem to migrate to new
check (and even if that
happened there's a ton of code that's already shipped and won't change).
The migration is straightfoward - replace all usages of `window` with
`globalThis` or `self`.
When Deno encounters use of `window` global it will now issue a warning,
steering users
towards required changes:
```
Warning
├ Use of deprecated "window" API.
│
├ This API will be removed in Deno 2.0. Make sure to upgrade to a stable API before then.

├ Suggestion: Use `globalThis` or `self` instead.

This commit adds support for [TC39 Decorator
Proposal](https://github.com/tc39/proposal-decorators).
These decorators are only available in transpiled sources - ie.
non-JavaScript files (because of lack of support in V8).
This entails that "experimental TypeScript decorators" are not available
by default
and require to be configured, with a configuration like this:
```
{
"compilerOptions": {
"experimentalDecorators": true
}
}
```

This change sets the removal version for the `deno bundle` sub-command
for Deno v2. The warnings appear when `deno bundle` is run and in the
`--help` menu.
Most uses of `Deno.resources()` within tests, as they previously checked
for leaked resources. This is not needed as the test runner does this
automatically. Other internal uses of this API have been replaced with
the internal `Deno[Deno.internal].core.resources()`.
This commit adds `import.meta.filename` and `import.meta.dirname` APIs.
These APIs return string representation of filename and containing
dirname.
They are only defined for local modules (modules that have `file:///`
scheme).
Example:
```ts
console.log(import.meta.filename, import.meta.dirname)
```
Unix:
```
$ deno run /dev/my_module.ts
/dev/my_module.ts /dev/
```
Windows:
```
$ deno run C:\dev\my_module.ts
C:\dev\my_module.ts C:\
```
This change:
1. Sets the removal version for `Deno.ListenTlsOptions.certFile`,
`Deno.ListenTlsOptions.keyFile` and `Deno.ConnectTlsOptions.certFile`
for Deno v2, in favour of the `cert`, `key` and `caCerts` options,
respectively.
2. Replaces use of the deprecated options with the new recommended
options.
Towards #22021
This initially uses the new diagnostic printer in `deno lint`,
`deno doc` and `deno publish`. In the limit we should also update
`deno check` to use this printer.
This commit deprecates "--unstable" flag.
When "--unstable" flag is encountered a warning like this is printed:
```
The `--unstable` flag is deprecated, use granular `--unstable-*` flags instead.
Learn more at: https://docs.deno.com/runtime/manual/tools/unstable_flags
```
When "--unstable" flag is used and an unstable API is called an
additional warning like this is printed for each API call:
```
The `Deno.dlopen` API was used with `--unstable` flag. The `--unstable` flag is deprecated, use granular `--unstable-ffi` instead.
Learn more at: https://docs.deno.com/runtime/manual/tools/unstable_flags
```
When no "--unstable-*" flag is provided and an unstable API is called
following
warning is issued before exiting:
```
Unstable API 'Deno.dlopen'. The `--unstable-ffi` flag must be provided.
```

Closes https://github.com/denoland/deno/issues/21828.
This API is a huge footgun. And given that "Deno.serveHttp" is a
deprecated API that is discouraged to use (use "Deno.serve()"
instead); it makes no sense to keep this API around.
This is a step towards fully migrating to Hyper 1.
This commit introduces deprecation warnings for "Deno.*" APIs.
This is gonna be quite noisy, but should tremendously help with user
code updates to ensure
smooth migration to Deno 2.0. The warning is printed at each unique call
site to help quickly
identify where code needs to be adjusted. There's some stack frame
filtering going on to
remove frames that are not useful to the user and would only cause
confusion.
The warning can be silenced using "--quiet" flag or
"DENO_NO_DEPRECATION_WARNINGS" env var.
"Deno.run()" API is now using this warning. Other deprecated APIs will
start warning
in follow up PRs.
Example:
```js
import { runEcho as runEcho2 } from "http://localhost:4545/run/warn_on_deprecated_api/mod.ts";
const p = Deno.run({
cmd: [
Deno.execPath(),
"eval",
"console.log('hello world')",
],
});
await p.status();
p.close();
async function runEcho() {
const p = Deno.run({
cmd: [
Deno.execPath(),
"eval",
"console.log('hello world')",
],
});
await p.status();
p.close();
}
await runEcho();
await runEcho();
for (let i = 0; i < 10; i++) {
await runEcho();
}
await runEcho2();
```

Closes #21839
This commit removes the requirement for `--unstable` flag in `deno
jupyter` subcommand. The process will no longer exit if this flag is not
provided, however the subcommand itself is still considered unstable
and might change in the future.
Required for https://github.com/denoland/deno/pull/21452
This commit adds support for [Stage 3 Temporal API
proposal](https://tc39.es/proposal-temporal/docs/).
The API is available when `--unstable-temporal` flag is passed.

We were calling `expand_glob` on our excludes, which is very expensive
and unnecessary because we can pattern match while traversing instead.
1. Doesn't expand "exclude" globs. Instead pattern matches while walking
the directory.
2. Splits up the "include" into base paths and applicable file patterns.
This causes less pattern matching to occur because we're only pattern
matching on patterns that might match and not ones in completely
unrelated directories.
This PR fixes #21658.
- `check` subcommand sees `exclude` option in `deno.json`. When some
paths passed with `check` command listed in `exclude`, they are ignored.
- When some files are listed in `exclude` and imported indirectly among
module graph, they are checked.
Harden the code that does permission checks to protect against
re-opening of stdin.
Code that runs FFI is vulnerable to an attack where fd 0 is closed
during a permission check and re-opened with a file that contains a
positive response (ie: `y` or `A`). While FFI code is dangerous in
general, we can make it more difficult for FFI-enabled code to bypass
additional permission checks.
- Checks to see if the underlying file for stdin has changed from the
start to the end of the permission check (detects races)
- Checks to see if the message is excessively long (lowering the window
for races)
- Checks to see if stdin and stderr are still terminals at the end of
the function (making races more difficult)
