This commit fixes "Add all missing imports" quick fix; before
it was replacing all occurrences with the same specifier. Now
every line returned from TSC is processed individually.
This commit adds "Deno.Conn.ref()" and "Deno.Conn.unref()" methods.
These methods can be used to make connection block or not block the
event loop from finishing. Refing/unrefing only influences "read"
operations - ie. scheduling writes to a connection _do_ keep event
loop alive.

This commit fixes handling of rejected promises in dynamic imports
evaluation.
Previously we were running callbacks for next ticks and macrotasks
_before_ polling
dynamic imports and checked for unhandled rejections immediately after.
This is wrong,
as `unhandledrejection` event is dispatched and its callbacks are run as
macrotasks.
This commit changes order of actions performed by the event loop to
following:
- poll async ops
- poll dynamic imports
- run next tick callbacks
- run macrotask callbacks
- check for unhandled promise rejections
This commit fixes formatting of JSError with "errors" property. Before this
commit all instances of "Error" were treated as if they were "AggregateError"
if they had "errors" property. After this commit only actual instances of
"AggregateError" are formatted in such a way, while instances of "Error"
that have "errors" property are formatted without showing details of "errors".
Previously, errored streaming response bodies did not cause the HTTP
stream to be aborted. It instead caused the stream to be closed gracefully,
which had the result that the client could not detect the difference
between a successful response and an errored response.
This commit fixes the issue by aborting the stream on error.
This PR adds the concept of a global `DrawThread`, which can receive
multiple renderers to draw information on the screen (note: the
underlying thread is released back to tokio when it's not rendering). It
also separates the concept of progress bars from the existing "draw
thread". This makes it trivial for us to do stuff like show permission
prompts and progress bars at the same time in the future.
The reason this is global is because the process' tty stderr is also a
global concept.
Right now an error in a request body stream causes an uncatchable
global promise rejection. This PR fixes this to instead propagate the
error correctly into the promise returned from `fetch`.
It additionally fixes errored readable stream bodies being treated as
successfully completed bodies by Rust.
The output of `init` are commands, so this should be treated as a "Shell
script". In Shell script, comments must start with `#`, not `//`. (This
also makes the commands example easier to be copied to somewhere.)
This commit changes implementation of "Deno.memoryUsage()" to return
correct value for "rss" field. To do that we implement a specialized function
per os to retrieve this information.
In our `require()` implementation we use a special logic to resolve
"base path" when looking for matching packages, however this logic
is in contradiction to what needs to happen if there's a local
"node_modules"
directory used. This commit changes require implementation to be aware
if we're running off of global node modules cache or a local one.
This commit adds new "--inspect-wait" flag which works similarly
to "--inspect-brk" in that it waits for inspector session to be
established before running code. However it doesn't break on the first
statement of user code, but instead runs it as soon as a session
is established.
This commit removes three unstable Deno APIs:
- "Deno.spawn()"
- "Deno.spawnSync()"
- "Deno.spawnChild()"
These APIs were replaced by a unified "Deno.Command" API.
This allows the user to completely opt out from the lock file or rename
it without having to use `--no-lock` and/or `--lock` in all commands.
## Don’t Use Lock File
```json
{
"lock": false
}
```
## Use Lock File With a Different Name
```json
{
"lock": "deno2.lock"
}
```
The CLI args `--no-lock` and `--lock` will always override what is in
the config file.

This commit changes "deno repl" command to run with no permissions by
default and accept "--allow-*" flags.
This change is dictated by the fact that currently there is no way to
run REPL with limited permissions. Technically it's a breaking
change in the CLI command, but there's agreement in the team
that it has merit and it's a good solution.
Running just "deno" command still starts the REPL with full permissions
allowed, but now a banner is printed to inform users about that:
We currently only do this for fmt. This makes it so they're excluded by
default, but you can still opt into these directories by explicitly
specifying them.
This commit adds "InspectorTester" struct which is used in
inspector tests - it encapsulated various functionalities that
we need (like reading/writing to WebSocket), but also adds
better error handling which should help with debugging flaky
tests.
Previously the inner request object of the original and the new request
were the same, causing the requests to be entangled and mutable changes
to one to be visible to the other. This fixes that.
Currently runtime exception are only displayed at the program end in
terminal, which makes it only a partial fix, as a full fix requires
https://github.com/denoland/rusty_v8/pull/1149 which adds new bindings
to the inspector that allows to notify it about thrown exceptions.
This will be handled in a follow up commit.
This commit completely rewrites inspector session polling.
Until now, there was a single function responsible for polling inspector
sessions which could have been called when polling the "JsRuntime"
as well as from internal inspector functions. There are some cases
where it's required to have reentrant polling of sessions (eg. when
"debugger" statement is run) which should be blocking until inspector
sends appropriate message to continue execution. This was not possible
before, because polling of sessions didn't have reentry ability.
As a consequence, session polling was split into two separate functions:
a) one to be used when polling from async context (on each tick of event
loop in "JsRuntime")
b) one to be used when polling synchronously and potentially blocking
(used by various inspector methods).
There are further cleanups and simplifications to be made in inspector
code, but this rewrite solves the problem at hand (being able to
evaluate
"debugger" JS statement and continue inspector functionality).

This commit updates unhelpful messages that are raised when event loop
stalls on unresolved top-level promises.
Instead of "Module evaluation is still pending but there are no pending
ops or dynamic imports. This situation is often caused by unresolved
promises." and "Dynamically imported module evaluation is still pending
but there are no pending ops. This situation is often caused by
unresolved promises." we are now printing a message like:
error: Top-level await promise never resolved

Refactors the `Deno.Command` class to not handle any state, but only being an intermediary to calling its methods, and as such any methods and properties besides `output`, `outputSync` & `spawn` have been removed. Interracting with a `spawn`ed subprocess now works by using the methods and properties on the returned class of the `spawn` method.

This reverts commit fd023cf793.
There are reports saying that Vite is often hanging in 1.28.2 and this

the only PR that changed something with HTTP server. I think we should
hold off on trying to fix this and instead focus on #16787

This commit allows to execute more JS code from extensions when
creating a snapshot from an existing snapshot.
"deno_core::RuntimeOptions::extensions_with_js" field was added
that is used to pass a list of extensions whose both "ops" and
associated JS source should be executed upon start.

This commit changes "JsRuntime" to send "executionContextDestroyed"
notification when the program finishes and shows a prompt informing
that runtime is waiting for inspector to disconnect.
With trial and error I found that most debuggers expect "isDefault" to be sent
in "auxData" field of "executionContextCreated" notification. This stems from
the fact that Node.js sends this data and eg. VSCode requires it to close
connection to the debugger when the program finishes execution.
This commit changes history handling of the REPL.
There were some situations were history wasn't properly saved and flushed to a
file, making history very spotty. This commit changes it to save every line into
the history file and flush it to disk before being evaluated.
Thanks to this all lines, including "close()" will be stored in the history
file.
If for any reason we're not able to save history file, a single warning will be
printed to the REPL and it will continue to work, even if subsequent tries will
fail to save to disk.
This PR resets the revert commit made by #16610, bringing back #16383
which attempts to fix the issue happening when we use the flash server
with `--watch` option enabled.
Also, some code changes are made to pass the regression test added in
#16610.
This code checks if permission flags are incorrectly defined after the
module name (e.g. `deno run mod.ts --allow-read` instead of the correct
`deno run --allow-read mod.ts`). If so, a simple warning is displayed.
For CommonJS packages we were not trying different extensions for files
specified as subpath of the package ([package_name]/[subpath]).
This commit fixes that.
If "--lock-write" flag was present we never passed instance of the lockfile to
the npm resolver, which made it skip adding discovered npm packages to
the lockfile. This commit fixes that, by always passing lockfile to the npm
resolver and only regenerating resolver snapshot is "--lock-write" is not
present.
Closes https://github.com/denoland/deno/issues/16666
Supports package names that aren't all lowercase.
This stores the package with a leading underscore (since that's not
allowed in npm's registry and no package exists with a leading
underscore) then base32 encoded (A-Z0-9) so it can be lowercased and
avoid collisions.
Global cache dir:
```
$DENO_DIR/npm/registry.npmjs.org/_{base32_encode(package_name).to_lowercase()}/{version}
```
node_modules dir `.deno` folder:
```
node_modules/.deno/_{base32_encode(package_name).to_lowercase()}@{version}/node_modules/<package-name>
```
Within node_modules folder:
```
node_modules/<package-name>
```
So, direct childs of the node_modules folder can have collisions between
packages like `JSON` vs `json`, but this is already something npm itself
doesn't handle well. Plus, Deno doesn't actually ever resolve to the
`node_modules/<package-name>` folder, but just has that for
compatibility. Additionally, packages in the `.deno` dir could have
collissions if they have multiple dependencies that only differ in
casing or a dependency that has different casing, but if someone is
doing that then they're already going to have trouble with npm and they
are asking for trouble in general.
If resolving types for an npm package, we didn't find "types" entry in
the conditional exports declaration we were falling-through to regular
resolution, instead of short-circuiting and giving up on resolving
types, which might lead to unwarranted errors.

Supports npm specifiers for `deno install`. This will by default always
use a lockfile (which is generated on first run) unless `--no-lock` is
specified.
Peer dependency resolution wasn't handling a peer dependency being
resolved without a dep higher in the tree and then with one being found
higher in the tree.

1. There was a lot of cloning going on with `NpmPackageInfo`. This is
now stored in an `Arc<NpmPackageInfo>` and cloning only happens on the
individual version.
2. The package cache is now cleared from memory after resolution.
3. This surfaced a bug in `deno cache` and I noticed it can be more
efficient if we have multiple root specifiers if we provide all the
specifiers as roots.
This PR adds copies of several unstable APIs that are available
in "Deno[Deno.internal].nodeUnstable" namespace.
These copies do not perform unstable check (ie. don't require
"--unstable" flag to be present). Otherwise they work exactly
the same, including permission checks.
These APIs are not meant to be used by users directly and
can change at any time.
Copies of following APIs are available in that namespace:
- Deno.spawnChild
- Deno.spawn
- Deno.spawnSync
- Deno.serve
- Deno.upgradeHttpRaw
- Deno.listenDatagram
This commit makes "npm:" specifiers not require "--unstable" flag.
At the moment some APIs used by Node polyfills still require
"--unstable" which will be addressed in follow up PRs.
This PR makes it possible for applications to create workers from custom
snapshots to improve runtime performance (without having to fork/copy
`runtime/workers.rs`).
This adds support for peer dependencies in npm packages.
1. If not found higher in the tree (ancestor and ancestor siblings),
peer dependencies are resolved like a dependency similar to npm 7.
2. Optional peer dependencies are only resolved if found higher in the
tree.
3. This creates "copy packages" or duplicates of a package when a
package has different resolution due to peer dependency resolution—see
https://pnpm.io/how-peers-are-resolved. Unlike pnpm though, duplicates
of packages will have `_1`, `_2`, etc. added to the end of the package
version in the directory in order to minimize the chance of hitting the
max file path limit on Windows. This is done for both the local
"node_modules" directory and also the global npm cache. The files are
hard linked in this case to reduce hard drive space.
This is a first pass and the code is definitely more inefficient than it
could be.
Closes #15823
This commit fixes CJS resolution when there's a local "node_modules/"
directory.
Before this commit relative imports from CJS files where resolved
relative to
root directory of the package instead of relative to referrer file.
When streaming a resource in ext/http, with compression enabled, we
didn't flush individual chunks. This became very problematic when we
enabled `req.body` from `fetch` for FastStream recently.
This commit now correctly flushes each resource chunk after compression.
This commit adds autodiscovery of lockfile.
This only happens if Deno discovers the configuration file (either
"deno.json" or "deno.jsonc"). In such case Deno tries to load
"deno.lock"
file that sits next to the configuration file, or creates one for user
if
the lockfile doesn't exist yet.
As a consequence, "--lock" and "--lock-write" flags had been updated.
"--lock" no longer requires a value, if one is not provided, it defaults
to "./deno.lock" resolved from the current working directory.
"--lock-write"
description was updated to say that it forces to overwrite a lockfile.
Autodiscovery is currently not handled by the LSP.
This commit changes lockfile to be "additive" - ie. integrity check only fails if
file/package is already specified in the lockfile, but its integrity doesn't match.
If file/package is not present in the lockfile, it will be added to the lockfile and
the lockfile will be written to disk.
In order for test cases to pass regardless of each individual's environment,
this commit adds calls to `slice` method when printing the filenames so
we can avoid getting `console.log` to truncate them.
Fixes #16305
This API needs `--allow-sys` permissions nowadays, but the docs still
mention `--allow-env` permissions.

├ Run again with --allow-sys to bypass this prompt.

This test has hung a lot recently on macOS. I am not sure if this is
because of a bug in the test or because of the macOS runner that is extremely
slow and flaky in general.
The "proposed" feature that we depend upon in tower-lsp, turns on the
"proposed" feature in lsp-types which has breaking changes in patch
releases because it's explicitly unstable. We need to pin it to prevent
it breaking cargo publish.
V8's JIT can do a better job knowing the argument count and also enable
fast call path (in future).
This also lets us call async ops without `opAsync`:
```js
const { ops } = Deno.core;
await ops.op_void_async();
```

main: 3508771 ops/sec
This commit stabilizes "Deno.consoleSize()" API.
There is one change compared to previous unstable API,
in that the API doesn't accept any arguments. Console size
is established by querying syscalls for stdio streams at fd
0, 1 and 2.
This commit adds a `reuseAddress` option for UDP sockets. When this
option is enabled, one can listen on an address even though it is
already being listened on from a different process or thread. The new
socket will steal the address from the existing socket.
On Windows and Linux this uses the `SO_REUSEADDR` option, while on other
Unixes this is done with `SO_REUSEPORT`.
This behavior aligns with what libuv does.
TCP sockets still unconditionally set the `SO_REUSEADDR` flag - this
behavior matches Node.js and Go. This PR does not change this behaviour.
Co-authored-by: Luca Casonato <hello@lcas.dev>
When listening on a UNIX socket path, Deno currently tries to unlink
this path prior to actually listening. The implementation of this
behaviour is VERY racy, involves 2 additional syscalls, and does not
match the behaviour of any other runtime (Node.js, Go, Rust, etc).
This commit removes this behaviour. If a user wants to listen on an
existing socket, they must now unlink the file themselves prior to
listening.
This change in behaviour only impacts --unstable APIs, so it is not
a breaking change.
This PR fixes a regression that caused deno binaries produced by the CI
release workflows to be larger than expected.
**The problem:** The build script will determine whether the linker
supports the `--export-dynamic-symbol-list` flag by looking at the glibc
version installed on the system. Ubuntu 20.04 ships with glibc 2.31,
which does not support this flag. Upon investigation, I discovered that
the CI pipeline does not use the gcc compiler provided by the
`build-essential` package, and instead uses *clang-14*, which does
support the new flag.
**The solution:** Whenever a custom C Compiler is configured, the build
script now assumes the compiler supports the
`--export-dynamic-symbol-list` flag. This is not always going to be the
case (you could use clang-8, for example), but it puts the onus on the
user making the override to ensure the compiler has support.
This will return deno builds for Linux to their previous size of ~100MB,
and also allow builds under older glibc/gcc versions to succeed. If a
user is compiling deno with a custom compiler that does not support this
new flag, however, their build will fail. I expect this is a rare
scenario, however, and suggest we cross that bridge if and when we come
to it.

There were still remaining bigint usages for pointers. This now finally
fixes all of them, there is only the one `type PointerValue = number |
bigint;` line that references `bigint` in the unstable type definition
file.
Potential fix for type-code mismatch in FFI buffer types. The code
supports ArrayBuffers, but types only reflect TypedArray support.
There's also an existing type for this sort of stuff: `BufferSource`.
(Although, it uses `ArrayBufferView` which doesn't actually connect with
the TypedArray interfaces specifically, but it's just a type inheritance
difference and nothing more.)

Makes `op_ffi_ptr_of` fast. One of the tests changed from printing
`false` to `true` as the fast `&[u8]` slice path creates the slice with
a null pointer. Thus the `op_ffi_ptr_of` will now return a null pointer
value whereas previously it returned a dangling pointer value.
This PR makes pointer read methods of `Deno.UnsafePointerView` Fast API
compliant, with the exception of `getCString` which cannot be made fast
with current V8 Fast API.
Introduces a new lockfile format that will be used to support locking
"npm" dependencies.
Currently the format looks as follows:
```
// This file is automatically generated by Deno, do not edit its contents
// manually. This file should be commited to your repository.
{
"version": "2",
"remote": {
"https://deno.land/std@0.160.0/http/server.ts": "asdwetsw44523asdfgfas..",
"https://deno.land/std@0.160.0/http/file_server.ts": "asdwetsw44523asdfgfas.."
}
}
```
A follow up PR will add "npm" key that will be used to store information
related
to "npm" dependencies and their resolution.
The new format is used when `--lock-write` is present, if user tries to
load
a lock file using the old format it will still work.
A small cleanup that improves errors in the lockfile as well
as prepares for adding a new format of the lock file that will
allow to provide backward compatibility with existing format
(ie. "Lockfile::content" will be changed into an enum "LockfileContent"
that will have "V1" and "V2" variants).
`deno task` has been in use for a few months now. It was very
well received and there are not many complaints. I feel like
this warning might be discouraging for some users and we don't
really plan to make drastic changes to it (besides adding support
for globs in unspecified future).
Tests and implementation are found here:
https://github.com/denoland/deno_task_shell/pull/59
This is a breaking change, but `deno task` is unstable.
> This changes async commands so that on non-zero exit code they will
fail the entire task. For example:
>
> ```jsonc
> // task that asynchronously starts a server and starts a watcher for
the frontend
> "dev": "deno task server & deno task frontend:watch"
> ```
>
> Previously when running `deno task dev`, if `deno task server` failed,
the entire command would not fail, which kept in line with `sh`, but
it's not very practical. This change causes `deno task dev` to fail.

> ```jsonc
> "dev": "deno task server || exit 0 & deno task frontend:watch"

This change adds `windowsRawArguments` to `SpawnOptions`. The option enables
skipping the default quoting and escaping while creating the command on
windows.
The option works in a similar way as `windowsVerbatimArguments` in
child_process.spawn options in Node.js, and is necessary for simulating
it in `std/node`.

Previously, the format for the Linux symbols list was simply a list of
symbols, now it follows the format:
```
{ symbol_name_a; ...; symbol_name_z };
```
Follow-up to #16208.
- Refactors build.rs behaviour to use `-exported_symbols_list` /
`--export-dynamic-symbol-list`
- Since all build systems now rely on a symbols list file, I have added
`generate_exported_symbols_list`, which derives the symbol list file
depending on the platform, which makes `tools/napi/generate_link_win.js`
redundant.
- Fixes a missed instance of `i8` being used instead of `c_char`

Fixes #15136
Currently `UnsafeCallback` class' `ref()` and `unref()` methods rely on
the `event_loop_middleware` implementation in core. If even a single
`UnsafeCallback` is ref'ed, then the FFI event loop middleware will
always return `true` to signify that there may still be more work for
the event loop to do.
The middleware handling in core does not wait a moment to check again,
but will instead synchronously directly re-poll the event loop and
middlewares for more work. This becomes a live-loop.
This PR introduces a `Future` implementation for the `CallbackInfo`
struct that acts as the intermediary data storage between an
`UnsafeCallback` and the `libffi` C callback. Ref'ing a callback now
means calling an async op that binds to the `CallbackInfo` Future and
only resolves once the callback is unref'ed. The `libffi` C callback
will call the waker of this Future when it fires to make sure that the
main thread wakes up to receive the callback.
This commit prevents panics that `deno compile` command ran into under certain
conditions from occurring. Such conditions are as follows.
- the target file name begins with `@`, OR
- the stem part of the target file name is equal to one of
["main", "index", "mod", "index"] && the parent directory name starts with `@`
Fixes #16243
This PR fixes invalid header parsing which is flaky because `g` flag is
being used in the regex, which keeps track of `lastIndex`
```javascript
try {
new Headers([["x", "\u0000x"]]); // error
} catch(e) {}
new Headers([["x", "\u0000x"]]); // no error
```
This issue affects `Response` & `Request` constructors as well
Changes introduced in #13633 have broken the ability to compile for
linux/aarch64 - specifically the use of a `i8` as a char type, which is
an `u8` on linux/aarch64.
This PR:
- Replaces instances of `i8` with the architecture-aware wrapper type
`c_char`
- Skips the use of `--export-dynamic-symbol` on linux-aarch64, because
the target environments often rely on older libc/binutils versions
This commit introduces two new buffer wrapper types to `deno_core`. The
main benefit of these new wrappers is that they can wrap a number of
different underlying buffer types. This allows for a more flexible read
and write API on resources that will require less copying of data
between different buffer representations.
- `BufView` is a read-only view onto a buffer. It can be backed by
`ZeroCopyBuf`, `Vec<u8>`, and `bytes::Bytes`.
- `BufViewMut` is a read-write view onto a buffer. It can be cheaply
converted into a `BufView`. It can be backed by `ZeroCopyBuf` or
`Vec<u8>`.
Both new buffer views have a cursor. This means that the start point of
the view can be constrained to write / read from just a slice of the
view. Only the start point of the slice can be adjusted. The end point
is fixed. To adjust the end point, the underlying buffer needs to be
truncated.
Readable resources have been changed to better cater to resources that
do not support BYOB reads. The basic `read` method now returns a
`BufView` instead of taking a `ZeroCopyBuf` to fill. This allows the
operation to return buffers that the resource has already allocated,
instead of forcing the caller to allocate the buffer. BYOB reads are
still very useful for resources that support them, so a new `read_byob`
method has been added that takes a `BufViewMut` to fill. `op_read`
attempts to use `read_byob` if the resource supports it, which falls
back to `read` and performs an additional copy if it does not. For
Rust->JS reads this change should have no impact, but for Rust->Rust
reads, this allows the caller to avoid an additional copy in many
scenarios. This combined with the support for `BufView` to be backed by
`bytes::Bytes` allows us to avoid one data copy when piping from a
`fetch` response into an `ext/http` response.
Writable resources have been changed to take a `BufView` instead of a
`ZeroCopyBuf` as an argument. This allows for less copying of data in
certain scenarios, as described above. Additionally a new
`Resource::write_all` method has been added that takes a `BufView` and
continually attempts to write the resource until the entire buffer has
been written. Certain resources like files can override this method to
provide a more efficient `write_all` implementation.
The current location was causing failures during v1.26.1 publication.

Currently, we use `-rdynamic` for exporting Node API symbols to the
symbol table. `-rdynamic` will export *all* symbols, that means
previously unused functions will not be optimized away introducing a lot
of binary bloat.
This patch uses `-exported_symbol` and `--export-dynamic-symbol` link
flags (not as universal as `-rdynamic`) to only mark Node API symbols to
be put in the dynamic symbol table.
This PR implements the NAPI for loading native modules into Deno.

Currently Content-Length is sent when the status code is 204. However,
according to the spec, this should not be sent.
Modify the if statement below to prevent the Content-Length from being
sent.
This commit adds a fast path to `Request` and `Response` that
make consuming request bodies much faster when using `Body#text`,
`Body#arrayBuffer`, and `Body#blob`, if the body is a FastStream.
Because the response bodies for `fetch` are FastStream, this speeds up
consuming `fetch` response bodies significantly.
This commit adds support for npm specifier in "deno cache" subcommand.
```
$ deno cache --unstable npm:vite npm:chalk https://deno.land/std/http/file_server.ts
```
Besides downloading requested npm package(s), it will also download
necessary code from "std/node/".
Make offering "virtual documents" via the lsp easier to parse. `deno:`
can be ambiguous to parse by editors (can conflict with linux paths)
Neovim recently landed a PR https://github.com/neovim/neovim/pull/19797
that allows it to parse `scheme:/` this PR should make deno lsp work
correctly in neovim
This commit adds a cache for CJS and ESM analysis that is backed by an
SQLite file.
The connection to the DB is lazily created on first use, so shouldn't
have impact on the startup time.

Stop allowing clippy::derive-partial-eq-without-eq and fix warnings
about deriving PartialEq without also deriving Eq.
In one case I removed the PartialEq because it a) wasn't necessary,
and b) sketchy because it was comparing floating point numbers.
IMO, that's a good argument for enforcing the lint rule, because it
would most likely have been caught during review if it had been enabled.
This commit allows the Node compatibility layer to skip
environment variable permission checks when --unstable
is passed and the variable name is one that Node uses.
