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.
```
deno run .\file.ts
⚠️ ┌ Deno requests sys access to "osRelease".
├ Requested by `Deno.osRelease()` API
├ Run again with --allow-sys to bypass this prompt.
└ Allow? [y/n] (y = yes, allow; n = no, deny) >
```
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.
