Fixes #23053.
Two small bugs here:
- the existing condition for printing out the group header was broken.
it worked in the reproducer (in the issue above) without filtering only
by accident, due to setting `self.has_ungrouped = true` once we see the
warmup bench. Knowing that we sort benchmarks to put ungrouped benches
first, there are only two cases: 1) we are starting the first group 2)
we are ending the previous group and starting a new group
- when you passed `--filter` we were applying that filter to the warmup
bench (which is not visible to users), so we suffered from jit bias if
you were filtering (unless your filter was `<warmup>`)
TLDR;
Running
```bash
deno bench main.js --filter="G"
```
```js
// main.js
Deno.bench({
group: "G1",
name: "G1-A",
fn() {},
});
Deno.bench({
group: "G1",
name: "G1-B",
fn() {},
});
```

This change removes deprecated methods from the `Deno.*` namespace when
the `DENO_FUTURE=1` environment variable is used.
Note: this does not address deprecated class properties and methods.
E.g. `Deno.Conn.rid`.
Before this PR, we didn't have any integration tests set up for the
`jupyter` subcommand.
This PR adds a basic jupyter client and helpers for writing integration
tests for the jupyter kernel. A lot of the code here is boilerplate,
mainly around the message format for jupyter.
This also adds a few basic integration tests, most notably for
requesting execution of a snippet of code and getting the correct
results.
This patch gets JUnit reporter to output more detailed information for
test steps (subtests).
## Issue with previous implementation
In the previous implementation, the test hierarchy was represented using
several XML tags like the following:
- `<testsuites>` corresponds to the entire test (one execution of `deno
test` has exactly one `<testsuites>` tag)
- `<testsuite>` corresponds to one file, such as `main_test.ts`
- `<testcase>` corresponds to one `Deno.test(...)`
- `<property>` corresponds to one `t.step(...)`
This structure describes the test layers but one problem is that
`<property>` tag is used for any use cases so some tools that can ingest
a JUnit XML file might not be able to interpret `<property>` as
subtests.
## How other tools address it
Some of the testing frameworks in the ecosystem address this issue by
fitting subtests into the `<testcase>` layer. For instance, take a look
at the following Go test file:
```go
package main_test
import "testing"
func TestMain(t *testing.T) {
t.Run("child 1", func(t *testing.T) {
// OK
})
t.Run("child 2", func(t *testing.T) {
// Error
t.Fatal("error")
})
}
```
Running [gotestsum], we can get the output like this:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<testsuites tests="3" failures="2" errors="0" time="1.013694">
<testsuite tests="3" failures="2" time="0.510000" name="example/gosumtest" timestamp="2024-03-11T12:26:39+09:00">
<properties>
<property name="go.version" value="go1.22.1 darwin/arm64"></property>
</properties>
<testcase classname="example/gosumtest" name="TestMain/child_2" time="0.000000">
<failure message="Failed" type="">=== RUN TestMain/child_2
 main_test.go:12: error
--- FAIL: TestMain/child_2 (0.00s)
</failure>
</testcase>
<testcase classname="example/gosumtest" name="TestMain" time="0.000000">
<failure message="Failed" type="">=== RUN TestMain
--- FAIL: TestMain (0.00s)
</failure>
</testcase>
<testcase classname="example/gosumtest" name="TestMain/child_1" time="0.000000"></testcase>
</testsuite>
</testsuites>
```
This output shows that nested test cases are squashed into the
`<testcase>` layer by treating them as the same layer as their parent,
`TestMain`. We can still distinguish nested ones by their `name`
attributes that look like `TestMain/<subtest_name>`.
As described in #22795, [vitest] solves the issue in the same way as
[gotestsum].
One downside of this would be that one test failure that happens in a
nested test case will end up being counted multiple times, because not
only the subtest but also its wrapping container(s) are considered to be
failures. In fact, in the [gotestsum] output above, `TestMain/child_2`
failed (which is totally expected) while its parent, `TestMain`, was
also counted as failure. As
https://github.com/denoland/deno/pull/20273#discussion_r1307558757
pointed out, there is a test runner that offers flexibility to prevent
this, but I personally don't think the "duplicate failure count" issue
is a big deal.
## How to fix the issue in this patch
This patch fixes the issue with the same approach as [gotestsum] and
[vitest].
More specifically, nested test cases are put into the `<testcase>` level
and their names are now represented as squashed test names concatenated
by `>` (e.g. `parent 2 > child 1 > grandchild 1`). This change also
allows us to put a detailed error message as `<failure>` tag within the
`<testcase>` tag, which should be handled nicely by third-party tools
supporting JUnit XML.
## Extra fix
Also, file paths embedded into XML outputs are changed from absolute
path to relative path, which is helpful when running the test suites in
several different environments like CI.
Resolves #22795

Fixes #22941.
In that case, the only file with coverage was the `test.ts` file. The
coverage reporter filters out test files before compiling its report, so
after filtering we were left with an empty set of files. Later on it's
assumed that there is at least 1 file to be reported on, and we panic.
Instead of panicking, just issue an error after filtering.
This commit fixes passing `MessagePort` instances to

Closes https://github.com/denoland/deno/issues/22935
Fixes #22158.
Basically reimplements the whole `StringDecoder` with a much more direct
translation (read like one-to-one) of node's current logic. The old
implementation was closer to node's super old impl and it was too hard
to keep the code structure while matching the behavior of their new
logic.
This adds support for UTF-16LE, ascii, and latin1.
This also enables the node_compat test, which now passes without
modification.

point.

Stub implementation of getCipherInfo(). Good enough for most cases.
Note: We do not support all OpenSSL ciphers (likely never will)
Fixes https://github.com/denoland/deno/issues/21805
Fixes #19214.
We were using the `idna` crate to implement our polyfill for
`punycode.toASCII` and `punycode.toUnicode`. The `idna` crate is
correct, and adheres to the IDNA2003/2008 spec, but it turns out
`node`'s implementations don't really follow any spec! Instead, node
splits the domain by `'.'` and punycode encodes/decodes each part. This
means that node's implementations will happily work on codepoints that
are disallowed by the IDNA specs, causing the error in #19214.
While fixing this, I went ahead and matched the node behavior on all of
the punycode functions and enabled node's punycode test in our
`node_compat` suite.

This does add a dependency on `signal-hook`, but it's just a higher

Adds a basic `Immediate` class to mirror `NodeJS.Immediate`, and changes
`setImmediate` and `clearImmediate` to return and accept (respectively)
`Immediate` objects.
Note that for now {ref,unref,hasRef} are effectively stubs, as deno_core
doesn't really natively support immediates (they're currently modeled as
timers with delay of 0). Eventually we probably want to actually
implement these properly.
This is an unrealistic scenario, but it's still a good thing to fix and
have a test for because it probably fixes some other underlying issues
with how the gitignore was being resolved for the root directory.
From https://github.com/denoland/deno/pull/22720#issuecomment-1986134425
This allows explicitly overriding a .gitignore by specifying files and
directories in "include". This does not apply to globs in an include as
files matching those will still be gitignored. Additionally,
individually gitignored files within an included directory will still be
ignored.
1. Stops `deno publish` using some custom include/exclude behaviour from
other sub commands
2. Takes ancestor directories into account when resolving gitignore
3. Backards compatible change that adds ability to unexclude an exclude
by using a negated glob at a more specific level for all sub commands
(see https://github.com/denoland/deno_config/pull/44).
An undocumented "DENO_DISABLE_PEDANTIC_NODE_WARNINGS" env
var can be used to silence warnings for sloppy imports and node builtins
without `node:` prefix.

This commit adds "deno add" subcommand that has a basic support for
adding "jsr:" packages to "deno.json" file.
This currently doesn't support "npm:" specifiers and specifying version
constraints.
Some `deno_std` tests were failing to print output that was resolved
after the last test finished. In addition, output printed before tests
began would sometimes appear above the "running X tests ..." line, and
sometimes below it depending on timing.
We now guarantee that all output is flushed before and after tests run,
making the output consistent.
Pre-test and post-test output are captured in `------ pre-test output
------` and `------ post-test output ------` blocks to differentiate
them from the regular output blocks.
Here's an example of a test (that is much noisier than normal, but an
example of what the output will look like):
```
Check ./load_unload.ts
------- pre-test output -------
load
----- output end -----
running 1 test from ./load_unload.ts
test ...
------- output -------
test
----- output end -----
test ... ok ([WILDCARD])
------- post-test output -------
unload
----- output end -----
```
A security feature of JSR is that it is self contained other than npm
dependencies. At publish time, the registry rejects packages that write
code like this:
```ts
const data = await import("https://example.com/evil.js");
```
However, this can be trivially bypassed by writing code that the
registry cannot statically analyze for. This PR prevents Deno from
loading dynamic imports that do this.
As we add tracing to more types of runtime activity, `--trace-ops` is
less useful of a name. `--trace-leaks` better reflects that this feature
traces both ops and timers, and will eventually trace resource opening
as well.
This keeps `--trace-ops` as an alias for `--trace-leaks`, but prints a
warning to the console suggesting migration to `--trace-leaks`.
One test continues to use `--trace-ops` to test the deprecation warning.

This PR enhances the `deno publish` command to infer dependencies from
`package.json` if present.
When using a prefix or suffix containing an invalid filename character,
it's not entirely clear where the errors come from. We make these errors
more consistent across platforms.
In addition, all permission prompts for tempfile and tempdir were
printing the same API name.
We also take the opportunity to make the tempfile random space larger by
2x (using a base32-encoded u64 rather than a hex-encoded u32).
1. Renames zap/fast-check to instead be a `no-slow-types` lint rule.
1. This lint rule is automatically run when doing `deno lint` for
packages (deno.json files with a name, version, and exports field)
1. This lint rules still occurs on publish. It can be skipped by running
with `--no-slow-types`
If we strip out unprintable chars, we don't see the full filename being
requested by permission prompts. Instead, we highlight and escape them
to make them visible.
This change deprecates
`Deno.CreateHttpClientOptions.{certChain,privateKey}` in favour of
`Deno.CreateHttpClientOptions.{cert,key}`.

The format of the sanitizers will change a little bit:
- If multiple async ops leak and traces are on, we repeat the async op
header once per stack trace.
- All leaks are aggregated under a "Leaks detected:" banner as the new
timers are eventually going to be added, and these are neither ops nor
resources.
- `1 async op` is now `An async op`
- If ops and resources leak, we show both (rather than op leaks masking
resources)
Follow-on to https://github.com/denoland/deno/pull/22226
This changes the lockfile to not store JSR specifiers in the "remote"
section. Instead a single JSR integrity is stored per package in the
lockfile, which is a hash of the version's `x.x.x_meta.json` file, which
contains hashes for every file in the package. The hashes in this file
are then compared against when loading.
Additionally, when using `{ "vendor": true }` in a deno.json, the files
can be modified without causing lockfile errors—the checksum is only
checked when copying into the vendor folder and not afterwards
(eventually we should add this behaviour for non-jsr specifiers as
well). As part of this change, the `vendor` folder creation is not
always automatic in the LSP and running an explicit cache command is
necessary. The code required to track checksums in the LSP would have
been too complex for this PR, so that all goes through deno_graph now.
The vendoring is still automatic when running from the CLI.
Based on #21074 and #20741 I was looking for further potential use cases
of `TransformStream` `cancel()` method, so here go `CompressionStream`
and `DecompressionStream`.
Fixes #14212
Note: tests are not the only part of the codebase that uses `std`. Other
parts, like `tools/`, do too. So, it could be argued that this is a
little misleading. Either way, I'm doing this as discussed with
@mmastrac.
This implementation heavily depends on there being a lockfile, meaning
JSR specifiers will always diagnose as uncached unless it's there. In
practice this affects cases where a `deno.json` isn't being used. Our
NPM specifier support isn't subject to this.
The reason for this is that the version constraint solving code is
currently buried in `deno_graph` and not usable from the LSP, so the
only way to reuse that logic is the solved-version map in the lockfile's
`packages.specifiers`.
This looks like a massive PR, but it's only a move from cli/tests ->
tests, and updates of relative paths for files.
This is the first step towards aggregate all of the integration test
files under tests/, which will lead to a set of integration tests that
can run without the CLI binary being built.
While we could leave these tests under `cli`, it would require us to
keep a more complex directory structure for the various test runners. In
addition, we have a lot of complexity to ignore various test files in
the `cli` project itself (cargo publish exclusion rules, autotests =
false, etc).
And finally, the `tests/` folder will eventually house the `test_ffi`,
`test_napi` and other testing code, reducing the size of the root repo
directory.
For easier review, the extremely large and noisy "move" is in the first
commit (with no changes -- just a move), while the remainder of the
changes to actual files is in the second commit.
This ensures the deno executable is properly created before running the integration tests.
Also allows deno_cli to be used as a lib. Docs are now properly generated: https://docs.rs/deno_cli/0.18.4/deno_cli/
Towards #2933
Prep for #2955
Instead of using core/snapshot_creator.rs, instead two crates are
introduced which allow building the snapshot during build.rs.
Rollup is removed and replaced with our own bundler. This removes
the Node build dependency. Modules in //js now use Deno-style imports
with file extensions, rather than Node style extensionless imports.
This improves incremental build time when changes are made to //js files
by about 40 seconds.
This removes dispatch_flatbuffers as it is now unused. There are still a
few places where msg_generated is used: ErrorKind and MediaType. These
will be dealt with later.

* define `use_cache` and `no_fetch` flags on `DenoDir` instead of using
in fetch methods
The rules are now as follows:
* In `import` statements, as mandated by the WHATWG specification,
the import specifier is always treated as a URL.
If it is a relative URL, it must start with either / or ./ or ../
* A script name passed to deno as a command line argument may be either
an absolute URL or a local path.
- If the name starts with a valid URI scheme followed by a colon, e.g.
'http:', 'https:', 'file:', 'foo+bar:', it always interpreted as a
URL (even if Deno doesn't support the indicated protocol).
- Otherwise, the script name is interpreted as a local path. The local
path may be relative, and operating system semantics determine how
it is resolved. Prefixing a relative path with ./ is not required.
* Compiler no longer has its own Tokio runtime. Compiler handles one
message and then exits.
* Uses the simpler ts.CompilerHost interface instead of
ts.LanguageServiceHost.
* avoids recompiling the same module by introducing a hacky but simple
`hashset<string>` that stores the module names that have been already
compiled.
* Removes the CompilerConfig op.
* Removes a lot of the mocking stuff in compiler.ts like `this._ts`. It
is not useful as we don't even have tests.
* Turns off checkJs because it causes fmt_test to die with OOM.
Removed `extmap` and added .mjs entry in `map_file_extension`.
The assert in the compiler does not need to be updated, since it is
resolving from the compiled cache instead of elsewhere (notice the .map
is asserted next to it)
This disables a few tests which are broken still:
- tests/error_004_missing_module.test
- tests/error_005_missing_dynamic_import.test
- tests/error_006_import_ext_failure.test
- repl_test test_set_timeout
- repl_test test_async_op
- repl_test test_set_timeout_interlaced
- all of permission_prompt_test
A major API change was that asserts are imported from testing/asserts.ts
now rather than testing/mod.ts and assertEqual as renamed to
assertEquals to conform to what is most common in JavaScript.
Resolves #1705
This PR adds the Deno APIs as a global namespace named `Deno`. For backwards
compatibility, the ability to `import * from "deno"` is preserved. I have tried
to convert every test and internal code the references the module to use the
namespace instead, but because I didn't break compatibility I am not sure.
On the REPL, `deno` no longer exists, replaced only with `Deno` to align with
the regular runtime.
The runtime type library includes both the namespace and module. This means it
duplicates the whole type information. When we remove the functionality from the
runtime, it will be a one line change to the library generator to remove the
module definition from the type library.
I marked a `TODO` in a couple places where to remove the `"deno"` module, but
there are additional places I know I didn't mark.
* Native ES modules
This is a major refactor of internal compiler.
Before: JS and TS both were sent through the typescript compiler where
their imports were parsed and handled. Both compiled to AMD JS and
finally sent to V8
Now: JS is sent directly into V8. TS is sent through the typescript
compiler, but tsc generates ES modules now instead of AMD. This
generated JS is then dumped into V8.
This should much faster for pure JS code. It may improve TS compilation
speed.
In the future this allows us to separate TS out of the runtime heap and
into its own dedicated snapshot. This will result in a smaller runtime
heap, and thus should be faster.
Some tests were unfortunately disabled to ease landing this patch:
1. compiler_tests.ts which I intend to bring back in later commits.
2. Some text_encoding_test.ts tests which made the file invalid utf8.
See PR for a discussion.
Also worth noting that this is necessary to support WASM
- Improves speed and binary size significantly.

* Fixed linting issues in ts tests.
