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.
Also don't panic on invalid domain names and addresses.

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 `fs.lutimes` and `fs.lutimesSync` to our node polyfills. To do
this I added methods to the `FileSystem` trait + ops to expose the
functionality to JS.
- Exports `fs._toUnixTimestamp`. Node exposes an internal util
`toUnixTimestamp` from the fs module to be used by unit tests (so we
need it for the unit test to pass unmodified). It's weird because it's
only supposed to be used internally but it's still publicly accessible
- Matches up error handling and timestamp handling for fs.futimes and
fs.utimes with node
- Enables the node_compat utimes test - this exercises futimes, lutimes,
and utimes.
Prevent panic when enabling a feature that is already enabled by
removing duplicate features.

Closes #18296.
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the lockfile is out of date.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out of date lockfile is usually a mistake) or to prevent accidental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
This commit adds discovery of `.npmrc` files in user's homedir.
This is not a perfect fix as it doesn't merge multiple `.npmrc` files
together as per https://github.com/denoland/deno/issues/23954
but allows to fallback if no `.npmrc` file is discovered in the project
root.
- add fallback impls of external string apis which always copy. after
upstream changes to rusty_v8 we can support non-copying api as well.
- `napi_get_buffer_data` needs to work on all TypedArray instances.
- Fixes: https://github.com/denoland/deno/issues/24209
- `target_defaults.default_configuration` is used by some modules to
find the corresponding node file from node-gyp
- `node_api_get_module_filename` expects the filename to be a `file:`
url.

Fixes #23493.
What was happening here was that napi-rs was freeing the napi reference
([here](19e3488efc/crates/napi/src/bindgen_runtime/mod.rs (L62)))
during its finalize callback (which we call
[here](fb31eaa9ca/cli/napi/js_native_api.rs (L132))).
We then were [reading the `ownership`
field](fb31eaa9ca/cli/napi/js_native_api.rs (L136))
of that freed reference.
For some reason on arm macs the freed memory gets zeroed, so the value
of `ownership` was `0` when we read it (i.e. it was
`ReferenceOwnership::Runtime`). We then freed it again (since we thought
we owned it), causing the segfault.
This commit updates Deno to use `reqwest` at 0.12.4
and `rustls` at 0.22. Other related crates were updated
as well to match versions accepted by `reqwest` and `rustls`.
Note: we are not using the latest available `rustls` yet,
but this upgrade was non-trivial already, so a bump to
0.23 for `rustls` will be done in a separate commit.

Fixes a regression introduced in
https://github.com/denoland/deno/pull/24170, where we wouldn't actually
set up the node modules dir on `deno install` if there was an up to date
deno lockfile present.
Previously we were relying on the fact that resolving pending module
resolution called `cache_packages` (which sets up the node modules dir).
When pending resolutions were removed, and the `resolve_pending`
function with it, we also removed the `cache_packages` call needed to
set up node modules.
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.
Previously various reads of files in `node_modules` would error on
invalid UTF-8. These were cases involving:
- reading package.json from Rust
- reading package.json from JS
- reading CommonJS files from JS
- reading CommonJS files from Rust (for ESM translation)
- reading ESM files from Rust
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.

Fixes #24012.
In the case of multiple packages providing a binary with a same name, we
were basically leaving the results undefined (since we set up things in
parallel, and whichever got set up first won). In addition, we were
warning about these cases, even though it's a situation that's expected
to occur.
Instead, in the case of a collision in the binary names, we prefer the
binary provided by the package with the least depth in the dependency
tree.
While I was at it, I also took moved more code to `bin_entries.rs` since
it was starting to get a bit cluttered.
This commits adds the ability to set a would-be exit code
for the Deno process without forcing an immediate exit,
through the new `Deno.exitCode` API.
- **Implements `Deno.exitCode` getter and setter**: Adds support for
setting
and retrieving a would-be exit code via `Deno.exitCode`.
This allows for asynchronous cleanup before process termination
without immediately exiting.
- **Ensures type safety**: The setter for `Deno.exitCode` validates that
the provided value is a number, throwing a TypeError if not, to ensure
that
only valid exit codes are set.

In https://github.com/denoland/deno/pull/23955 we changed the sqlite db
journal mode to WAL. This causes issues when someone is running an old
version of Deno using TRUNCATE and a new version because the two fight
against each other.
The same issue in two different places - doing blocking FS work in an
async task, limiting the amount of work that happens concurrently.
- When setting up node_modules, where we try to set up entries
concurrently but were blocking other tasks from actually running.
- When loading package info from the npm registry file cache, loading
and deserializing is expensive and prevents concurrency. This was
especially noticeable when loading an npm resolution snapshot from a
lockfile (`snapshot_from_lockfile` in `deno_npm`).

The mixed `number | bigint` representation was useful optimization for
pointers. Now, pointers are represented as V8 externals. As part of the
FFI stabilization effort we want to make `bigint` the only
representation for `u64` and `i64`.
BigInt representation performance is almost on par with mixed
representation with the added benefit that its less confusing and users
don't need manual checks and conversions for doing operations on the
value.

Enhanced warning message for --env flag with run and eval subcommands.
The commit is specifically made to address issue #23674 by improving the
warning messages that appear when using the --env flag with run or eval
subcommands in the following scenarios:
1. Missing environment file.
2. Incorrect syntax in the environment file content.
**Changes made**
- Distinguishes between cases of missing environment file and wrong
syntax in the environment file content.
- Shows a concise warning message to convey the case/issue occurred.
**Code changes & enhancements**
- Implemented a match statement to handle different types of errors
received while getting and parsing the file content to display a concise
warning message, rather than simple error check and then displaying the
same warning message for whatever the type of error is.
- Updated the related existing tests to reflect the new warning
messages.
- Added two test cases to cover the wrong environment file content
syntax with both run and eval subcommands.
**Impact**
The use of --env flag with both run/eval would be more user-friendly as
it gives a precise description of what is not right when using
incorrectly.
If you could give it a look, @dsherret , I appreciate your feedback on
these changes.

This commit adds initial support for ".npmrc" files.
Currently we only discover ".npmrc" files next to "package.json" files
and discovering these files in user home dir is left for a follow up.
This pass supports "_authToken" and "_auth" configuration
for providing authentication.
LSP support has been left for a follow up PR.

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.

While investigating poor cold start performance on my GCP VM (32 cores,
130GB SSD), I found that writing to the various sqlite databases in
DENO_DIR was quite slow. The slowness seems to primarily be caused by
excessive latency from a number of `fsync()` calls.
The performance difference is best demonstrated by deleting the sqlite
databases from DENO_DIR while leaving the downloaded sources in place.
The benchmark (see notes below):

```
Notes:
* Benchmark 1: unmodified Deno 1.43.6
* Benchmark 2: unmodified Deno 1.43.6 wrapped with `eatmydata` (which is
a tool to neuter `fsync()` calls)
* Benchmark 3: this PR applied on top of Deno 1.43.6

```typescript
// demo.ts
import * as express from "npm:express@4.16.3";
import * as postgres from "https://deno.land/x/postgres/mod.ts";
let _dummy = [express, postgres]; // Force use of imports.

Related: https://github.com/denoland/eszip/pull/181
eszip < v0.69.0 hashes all its contents to ensure data integrity. This
feature is not necessary in Deno CLI as the binary integrity guarantee
is deemed an external responsibility (ie it is to be assumed that, if
necessary, the compiled binary will be checksumed externally prior to
being executed).
eszip >= v0.69.0 no longer performs this checksum by default. This
reduces the cold-start time of the compiled binaries, proportionally to
their size.
VScode will typically send a `textDocument/semanticTokens/full` request
followed by `textDocument/semanticTokens/range`, and occassionally
request semantic tokens even when we know nothing has changed. Semantic
tokens also get refreshed on each change. Computing semantic tokens is
relatively heavy in TSC, so we should avoid it as much as possible.
Caches the semantic tokens for open documents, to avoid making TSC do
unnecessary work. Results in a noticeable improvement in local
benchmarking

When we should use `println` or `eprintln`, it's not too bad to be a bit

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)

Fixes the `Debug Failure` errors described in
https://github.com/denoland/deno/issues/23643#issuecomment-2094552765 .
The issue here was that we were passing diagnostic codes as strings but
TSC expects the codes to be numbers. This resulted in some quick fixes
not working (as illustrated by the test added here which fails before
this PR).
The first commit is the actual fix. The rest are just test related.
Fixes #23643.
We weren't catching the cancellation exception thrown by TSC on the JS
side, so the rust side was catching this exception and then attempting
to print out the exception via `toString`. That last bit resulted in a
cryptic `[object Object]` showing up in the logs like so:
```
Error during TS request "getCompletionEntryDetails":
[object Object]
```
I'm not 100% sure how we weren't seeing this in the past. My guess is
that #23409 and the subsequent PR to improve the exception catching and
logging surfaced this, but I'm still not quite clear on it.
My initial fix here returned `null` to rust when a server request was
cancelled, but this resulted in a deserialization error when we
attempted to deserialize that into the expected response type. So now,
as soon as the request's cancellation token signals we'll stop waiting
for a response and return an error (which will get swallowed as the LSP
request is being cancelled).
I was a bit surprised to find that [this
branch](0c671c9792/cli/lsp/tsc.rs (L1093))
actually executes sometimes, I believe due to the fact that aborting a

Before this PR, there would just be an uninformative "Error occurred"
message, after this PR you'll get a stack trace in the LSP output window
like this:
```text
Error during TS request "$getSupportedCodeFixes":
Error: i threw an exception
at serverRequest (ext:deno_tsc/99_main_compiler.js:1089:11)
```
By default, `deno serve` will assign port 8000 (like `Deno.serve`).
Users may choose a different port using `--port`.
`deno serve /tmp/file.ts`
`server.ts`:
```ts
export default {
fetch(req) {
return new Response("hello world!\n");
},
};
```
When the response has been successfully send, we abort the
`Request.signal` property to indicate that all resources associated with
this transaction may be torn down.

This PR wires up a new `jsxPrecompileSkipElements` option in
`compilerOptions` that can be used to exempt a list of elements from
being precompiled with the `precompile` JSX transform.
The actual handling of `$projectChanged` is quick, but JS requests are
not. The cleared caches only get repopulated on the next actual request,
so just batch the change notification in with the next actual request.
No significant difference in benchmarks on my machine, but this speeds
up `did_change` handling and reduces our total number of JS requests (in
addition to coalescing multiple JS change notifs into one).
Embedders may have special requirements around file opening, so we add a
new `check_open` permission check that is called as part of the file
open process.
Adds an `addr` field to `HttpServer` to simplify the pattern
`Deno.serve({ onListen({ port } => listenPort = port })`. This becomes:
`const server = Deno.serve({}); port = server.addr.port`.
Changes:
- Refactors `serve` overloads to split TLS out (in preparation for
landing a place for the TLS SNI information)
- Adds an `addr` field to `HttpServer` that matches the `addr` field of
the corresponding `Deno.Listener`s.

This allows people to use imports like:
```ts
import "./app.css";
```
...with `deno check` in systems where there's a bundle step (ex. Vite).
This will still error when using it with `deno run` or if the referenced
file does not exist.

This PR adds a benchmark intended to measure how the LSP handles larger
repos, as well as its performance on a more realistic workload.
The repo being benchmarked is
[deco-cx/apps](https://github.com/deco-cx/apps) which has been vendored
along with its dependencies. It's included as a git submodule as its
fairly large. The LSP requests used in the benchmark are the actual
requests sent by VSCode as I opened, modified, and navigated around a
file (to simulate an actual user interaction).
The main motivation is to have a more realistic benchmark that measures
how we do with a large number of files and dependencies. The
improvements made from 1.42 to 1.42.3 mostly improved performance with
larger repos, so none of our existing benchmarks showed an improvement.
Here are the results for the changes made from 1.42 to 1.42.3 (the new
benchmark is the last one listed):
**1.42.0**

`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
I'm running into a node resolution bug in the lsp only and while
tracking it down I noticed this one.
Fixed by moving the project version out of `Documents`.
…faces (#23296)"
This reverts commit e190acbfa8.
Reverting because it broke stable API type declarations. We will reland
it for v1.43 with updated interfaces
Fixes the regression described in
https://github.com/denoland/deno/pull/23293#issuecomment-2049819724.
This affected jupyter notebooks, as the LSP was passing in already
denormalized specifiers, while the jupyter kernel was not. We need to
denormalize the specifiers to evict the proper keys from our caches.
Currently we evict a lot of the caches on the JS side of things on every
request, namely script versions, script file names, and compiler
settings (as of #23283, it's not quite every request but it's still
unnecessarily often).
This PR reports changes to the JS side, so that it can evict exactly the
caches that it needs too. We might want to do some batching in the
future so as not to do 1 request per change.
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.
Removes the certificate options from all the interfaces and replaces
them with a new `TlsCertifiedKeyOptions`. This allows us to centralize
the documentation for TLS key management for both client and server, and
will allow us to add key object support in the future.
Also adds an option `keyFormat` field to the cert/key that must be
omitted or set to `pem`. This will allow us to load other format keys in
the future `der`, `pfx`, etc.
In a future PR, we will add a way to load a certified key object, and we
will add another option to `TlsCertifiedKeyOptions` like so:
```ts
export interface TlsCertifiedKeyOptions =
| TlsCertifiedKeyPem
| TlsCertifiedKeyFromFile
| TlsCertifiedKeyConnectTls
| { key: Deno.CertifiedKey }
```
Previously we locked the entire `FileSystemDocuments` even for lookups,
causing contention. This was particularly bad because some of the hot
ops (namely `op_resolve`) can end up hitting that lock under contention.
This PR replaces the mutex with synchronization internal to
`FileSystemDocuments` (an `AtomicBool` for the dirty flag, and then a
`DashMap` for the actual documents).
I need to think a bit more about whether or not this introduces any
problematic race conditions.
Changes `discreet` in the documentation for `discrete`
"Discreet" means careful to avoid being noticed, "discrete" means
separate parts, and is what the documentation refers to.
The TS language service requests source files via
[getSourceFile](7a25fd5ef0/cli/tsc/99_main_compiler.js (L560)).
In that function, we [unconditionally
add](7a25fd5ef0/cli/tsc/99_main_compiler.js (L613-L614))
the source file to our sourceFileCache. The issue is that we only remove
things from that cache if the source file [becomes out of
date](7a25fd5ef0/cli/tsc/99_main_compiler.js (L777-L783)).
For files that don't get changed, we keep them in the cache
indefinitely. So sometimes we keep SourceFile objects from being GC'ed
because they're retained in our cache, even though TS doesn't refer to
them any more. I see this in pretty much all of the heap snapshots I've
taken.
---
The fix here is pretty direct - just store weak references to the
sourcefiles in the cache. It doesn't really change our caching behavior,
it just prevents us from being the only retainer of a `SourceFile`. I
also split the `sourceFileCache` into a separate cache just for assets,
as we rely on those being alive.
The simpler fix is to only cache assets, but presumably that has a perf
impact.
---
In local testing, this PR reduced the size of the JS heap by about 1 GB
when using `deno lsp` in the Typescript repo.
This functionality was broken. The series of events was:
1. Load the npm resolution from the lockfile.
2. Discover only a subset of the specifiers in the documents.
3. Clear the npm snapshot.
4. Redo npm resolution with the new specifiers (~500ms).
What this now does:
1. Load the npm resolution from the lockfile.
2. Discover only a subset of the specifiers in the documents and take
into account the specifiers from the lockfile.
3. Do not redo resolution (~1ms).
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 adds enum to "InstallFlags" and "UninstallFlags" that will
allow to support both local and global (un)installation.
Currently the local variant is not used.

Fixes #23163.
The client-facing warning doesn't provide any value and is super
annoying. We still emit a warning message on the server side for format
errors, which should fulfill the same (less intrusive) purpose.
When `DENO_FUTURE=1` env var is present, then BYONM
("bring your own node_modules") is enabled by default.
That means that is there's a `package.json` present, users
are expected to explicitly install dependencies from that file.

Was doing a bit of debugging on why some stuff is not working in a
personal project and ran a quick debug profile and saw it cloning the
pkg json a lot. We should put this in an Rc.
Unused locals and parameters don't make sense to surface in remote
modules. Additionally, fast check can cause these kind of diagnostics
when publishing, so they should be ignored.
Closes #22959
Was investigating a separate stack overflow (that I've now found in the
node resolution code) and came across this. We should avoid recursion
(this is very old code).
This PR introduces the ability to exclude certain paths from the file watcher
in Deno. This is particularly useful when running scripts in watch mode,
as it allows developers to prevent unnecessary restarts when changes are
made to files that do not affect the running script, or when executing
scripts that generate new files which results in an infinite restart
loop.

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.

This has been incorrect since the function adopted its (more intuitive)
current behavior in 9268df5f3. The same behavior change was backported
to v1.39.3 in 87e954f54.
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.
In addition to the reasons for this outlined by @nayeemrmn in #14877
(which I think are reasons alone to not do this), this simplifies things
a lot because then we don't need to implement the following:
1. Need to handle a JSR module dynamically importing a module within it.
2. Need to handle importing an export of a JSR dep then another export
dynamically loaded later.
Additionally, people should be running `deno check dynamic_import.ts`
instead of relying on this behaviour.
Landing this as a fix because it's blocking people in some scenarios and
the current behaviour is broken (I didn't even have to change any tests
to remove this, which is bad).

Skips the access check if the specific unary permission is in an
all-granted state. Generally prevents an allocation or two.
Hooks up a quiet "all" permission that is automatically inherited. This
permission will be used in the future to indicate that the user wishes
to accept all side-effects of the permissions they explicitly granted.
The "all" permission is an "ambient flag"-style permission that states
whether "allow-all" was passed on the command-line.

This PR moves `runtime/permissions` code to a upstream crate called
`deno_permissions`. The `deno_permissions::PermissionsContainer` is put
into the OpState and can be used instead of the current trait-based
permissions system.
For this PR, I've migrated `deno_fetch` to the new crate but kept the
rest of the trait-based system as a wrapper of `deno_permissions` crate.
Doing the migration all at once is error prone and hard to review.

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
Previously the sloppy resolver could not resolve the following:
- foo/bar.ts
- foo.ts
- index.ts
Where `index.ts` contains `import "./foo"`, because it did not consider
`foo.ts` a valid target for this directory import.
This commit fixes this bug.

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).
