Permission flags are unified in a clearer and concise output.
Unstable flags are hidden by default with exception of the `unstable`
flag itself. the remaining unstable flags can be seen with a
`--help=unstable`.
This also cleans up to show unstable flags only for subcommands that
actually need them.
Also sorts flags alphabetically, and gorups various flags together in a
set of categories.

This commit fixes computation of the latest available version
by taking into account which release channel the current
binary is on.
Before this commit, if user was on "RC" channel, calling
`deno upgrade` would not switch back to the "stable"
channel.
This commits add a CI script that allows to promote a certain
canary build to a "Release Candidate" release.
This is done using `libsui` and `patchver` utilities.
This commit rewrites the internal `version` module that exported
various information about the current executable. Instead of exporting
several consts, we are now exporting a single const structure that
contains all the necessary information.
This is the first step towards cleaning up how we use this information
and should allow us to use SUI to be able to patch this information
in already produced binary making it easier to cut new releases.

From upgrading `deno_lint`.
Previously if you had a node project that used a bunch of node globals
(`process.env`, etc), you would have to fix the errors by hand. This PR
includes a new lint that detects usages of node globals (`process`,
`setImmediate`, `Buffer`, etc.) and provides an autofix to import the
correct value. For instance:
```ts
// main.ts
const _foo = process.env.FOO;
```
`deno lint` gives you
```ts
error[no-node-globals]: NodeJS globals are not available in Deno
--> /home/foo.ts:1:14
|
1 | const _foo = process.env.FOO;
| ^^^^^^^
= hint: Add `import process from "node:process";`
docs: https://lint.deno.land/rules/no-node-globals
Found 1 problem (1 fixable via --fix)
Checked 1 file
```
And `deno lint --fix` adds the import for you:
```ts
// main.ts
import process from "node:process";
const _foo = process.env.FOO;
```
In preparation for https://github.com/denoland/deno/pull/25014, this
commit removes public `is_canary()` method and instead uses an enum
`ReleaseChannel` to be able to designate more "kinds" of builds.
Adds a `parallel` flag to `deno serve`. When present, we spawn multiple
workers to parallelize serving requests.
```bash
deno serve --parallel main.ts
```
Currently on linux we use `SO_REUSEPORT` and rely on the fact that the
kernel will distribute connections in a round-robin manner.
On mac and windows, we sort of emulate this by cloning the underlying
file descriptor and passing a handle to each worker. The connections
will not be guaranteed to be fairly distributed (and in practice almost
certainly won't be), but the distribution is still spread enough to
provide a significant performance increase.

These errors are caused by the fact that the test server doesn't have an
endpoint to return
RC releases. Which in turn causes an error to be raised which later just
short-circuits logic
for checking the version and storing it in file. Since fetching from a
remote host is always
fallible I elected to just return an empty vec of "rc" versions instead
of erroring. This might
lead to a slight mismatch in some situation when the request actually
failed and user is
prompted that there's a new canary version, but that is better than not
displaying
prompt at all. This issue will be fixed more robustly once we move to
using SUI for
specifying version of the binary.
This commit adds the "--rc" flag to "deno upgrade" subcommand.
This flag allows to upgrade to the latest "release candidate" release.
The update checker was also updated to take this into account.
This commit stabilizes HMR functionality and renames

It will be removed in Deno 2.
Once https://github.com/denoland/deno/pull/24958 lands
we should improve grouping of `--watch` and `--watch-hmr`
flags.

This PR updates `deno run` to fallback to executing tasks when there is
no script with the specified name. If there are both script and a task
with the same name then `deno run` will prioritise executing the script.
This moves YAML formatting behind an unstable flag for Deno 1.46. This
will make it opt-in to start and then we can remove the flag to make it
on by default in version of Deno after that.
This can be specified by doing `deno fmt --unstable-yaml` or by
specifying the following in a deno.json file:
```json
{
"unstable": ["fmt-yaml"]
}
```
Uses [sui](https://github.com/littledivy/sui) to inject metadata as a

This commit fixes memory leak described in
https://github.com/denoland/deno/issues/24380.
This is done by upgrading following crates:
- deno_ast
- deno_graph
- eszip
- dprint-plugin-typescript
- deno_lint
- deno_doc
- deno_emit
Adds support for running npm package lifecycle scripts, opted into via a
new `--allow-scripts` flag.
With this PR, when running `deno cache` (or `DENO_FUTURE=1 deno
install`) you can specify the `--allow-scripts=pkg1,pkg2` flag to run
lifecycle scripts attached to the given packages.
Note at the moment this only works when `nodeModulesDir` is true (using
the local resolver).
When a package with un-run lifecycle scripts is encountered, we emit a
warning suggesting things may not work and to try running lifecycle
scripts. Additionally, if a package script implicitly requires
`node-gyp` and it's not found on the system, we emit a warning.
Extra things in this PR:
- Extracted out bits of `task.rs` into a separate module for reuse
- Added a couple fields to `process.config` in order to support
`node-gyp` (it relies on a few variables being there)
- Drive by fix to downloading new npm packages to test registry
---
TODO:
- [x] validation for allow-scripts args (make sure it looks like an npm
package)
- [x] make allow-scripts matching smarter
- [ ] figure out what issues this closes

Review notes:
- This adds a bunch of deps to our test registry due to using
`node-gyp`, so it's pretty noisy

The `jest` test runner popularized putting tests into a `__tests__`
folder. Whilst many have switched to going with a `.test` suffix in the
file name these days, there are still many jest projects that have
`__tests__`. By adding this to the default test detection logic it makes
`deno test` discover those out of the box.

Adds much better support for the unstable Deno workspaces as well as
support for npm workspaces. npm workspaces is still lacking in that we
only install packages into the root node_modules folder. We'll make it
smarter over time in order for it to figure out when to add node_modules
folders within packages.
This includes a breaking change in config file resolution where we stop
searching for config files on the first found package.json unless it's
in a workspace. For the previous behaviour, the root deno.json needs to
be updated to be a workspace by adding `"workspace":
["./path-to-pkg-json-folder-goes-here"]`. See details in

Adds a `--frozen` (alias `--frozen-lockfile`) flag that errors out if
the lockfile is out of date. This is useful for running in CI (where an
out of date lockfile is usually a mistake) or to prevent accidental
changes in dependencies.
As suggested in
https://github.com/denoland/deno/pull/24355#discussion_r1657875422.
I wasn't able to hide the mutex stuff as much as I'd like (ended up just
adding an escape hatch `inner()` method that locks the inner mutex),
because you can't return references to the inner fields through a mutex.
This is mostly motivated by the frozen lockfile changes
Fixes #22050.
It seems very unlikely that a user would be intending to enable deno's
internal debug logs by setting the DEBUG env var. If they really want
that, they can set `RUST_LOG=debug` instead.
Also removes permissions being passed in for node resolution. It was
completely useless because we only checked it for reading package.json
files, but Deno reading package.json files for resolution is perfectly
fine.
My guess is this is also a perf improvement because Deno is doing less
work.
Brings in:
* More fully typed structures (for when we get to implementing more)
* `with_metadata`, `with_buffers`, etc. from

In https://github.com/denoland/deno/pull/23955 we changed the sqlite db

This commit adds initial support for ".npmrc" files.
Currently we only discover ".npmrc" files next to "package.json" files

LSP support has been left for a follow up PR.
Towards https://github.com/denoland/deno/issues/16105
Fixes #23571.
Previously, we required a `deno.json` to be present (or the `--lock`
flag) in order for us to resolve a `deno.lock` file. This meant that if
you were using deno in an npm-first project deno wouldn't use a
lockfile.
Additionally, while I was fixing that, I discovered there were a couple
bugs keeping the future `install` command from using a lockfile.
With this PR, `install` will actually resolve the lockfile (or create
one if not present), and update it if it's not up-to-date. This also
speeds up `deno install`, as we can use the lockfile to skip work during
npm resolution.
This PR removes the use of the custom `utc_now` function in favor of the
`chrono` implementation. It resolves #22864.

Jupyter. Deno users will be able to install and use the kernel with just
VS Code or other editors that support Jupyter.

This PR directly addresses the issue raised in #23282 where Deno panics

I've opted not to change the return value of `collect_summary` for
simplicity and return an empty `HashMap` instead
1. Generally we should prefer to use the `log` crate.
2. I very often accidentally commit `eprintln`s.
When we should use `println` or `eprintln`, it's not too bad to be a bit
more verbose and ignore the lint rule.
This PR implements the changes we plan to make to `deno install` in deno
2.0.
- `deno install` without arguments caches dependencies from
`package.json` / `deno.json` and sets up the `node_modules` folder
- `deno install <pkg>` adds the package to the config file (either
`package.json` or `deno.json`), i.e. it aliases `deno add`
- `deno add` can also add deps to `package.json` (this is gated behind
`DENO_FUTURE` due to uncertainty around handling projects with both
`deno.json` and `package.json`)
- `deno install -g <bin>` installs a package as a globally available
binary (the same as `deno install <bin>` in 1.0)

`TestEventSender` should not be Clone so we don't end up with multiple
copies of the same writer FD. This is probably not the cause of the test
channel lockups, but it's a lot easier to reason about.
Due to a terminating NUL that was placed in a `r#` string, we were not
actually NUL-terminating pipe names on Windows. While this has no
security implications due to the random nature of the prefix, it would
occasionally cause random failures when the trailing garbage would make
the pipe name invalid.
This commit moves logic of dispatching lifecycle events (
"load", "beforeunload", "unload") to be triggered from Rust.
Before that we were executing scripts from Rust, but now we
are storing references to functions from "99_main.js" and calling
them directly.
Prerequisite for https://github.com/denoland/deno/issues/23342
This is PR a smaller retry of #23066 that simply ensures all async
`ext/fs` ops are accounted for if left hanging in tests. This also sorts
the `OP_DETAILS` in alphabetical order for easy future reading.
When reviewing, it might be best to look at the commits in order for
better understanding.
The tests would deadlock if we tried to write the sync marker into a
pipe that was full because one test streamed just enough data to fill
the pipe, so when we went to actually write the sync marker we blocked
when nobody was reading.
We use a two-phase lock for sync markers now: one to indicate "ready to
sync" and the second to indicate that the sync bytes have been received.

This commit changes "deno init" subcommand to use "jsr:" specifier for
standard library "assert" module. It is unversioned, but we will change
it to `@^1` once `@std/assert` release version 1.0.
This allows us to start decoupling `deno` and `deno_std` release. The
release scripts have been updated to take that into account.
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() {},
});

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.

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.
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).
We emitted `import "./` rather than `import "./$NAME"`. This is now
fixed.
Also makes a cosmetic change so that `../` imports are now just imported
as `../`, not `./../`.
Improves #19100
Fixes #20356
Replaces #20428
Changes made in deno_core to support this:
- [x] Errors must be handled in setTimeout callbacks
- [x] Microtask ordering is not-quite-right
- [x] Timer cancellation must be checked right before dispatch
- [x] Timer sanitizer
- [x] Move high-res timer to deno_core
- [x] Timers need opcall tracing
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.
