This commit adds "deno jupyter" subcommand which
provides a Deno kernel for Jupyter notebooks.
The implementation is mostly based on Deno's REPL and
reuses large parts of it (though there's some clean up that
needs to happen in follow up PRs). Not all functionality of
Jupyter kernel is implemented and some message type
are still not implemented (eg. "inspect_request") but
the kernel is fully working and provides all the capatibilities
that the Deno REPL has; including TypeScript transpilation
and npm packages support.

This is a mitigation for segfaults happening in V8 on CPU with MPK
(memory protected keys).
After much trail and error we found that unless V8 platform is
initialized on main thread the segfaults start appears once JIT
kicks in. "deno test" and "deno bench" were affected by
this problem.

Moves the watch setting out of the `Flags` struct and into the
individual subcommands

This commit adds ability to print metrics of the Tokio
runtime to the console by passing "DENO_TOKIO_METRICS=1"
env var.
Metrics will be printed every second, but this can be changed
by "DENO_TOKIO_METRICS_INTERVAL=500" env var.

This reverts commit 798c1ad0f1de80ff0e7196b6140a3f74e31fe111.
Reverting because this change caused a spike in memory usage, but we
can't fully realise gains from lower GC pressure from more optimal
malloc/ free provided by "jemalloc".
We might revisit the topic in future.

This fixes `Unhandled exception at [...] Stack overflow` on Windows,
caused by the large size of the main future.

(#19056)
Partially supersedes #19016.
This migrates `spawn` and `spawn_blocking` to `deno_core`, and removes
the requirement for `spawn` tasks to be `Send` given our single-threaded
executor.
While we don't need to technically do anything w/`spawn_blocking`, this
allows us to have a single `JoinHandle` type that works for both cases,
and allows us to more easily experiment with alternative
`spawn_blocking` implementations that do not require tokio (ie: rayon).

This is the initial support for npm and node specifiers in `deno
compile`. The npm packages are included in the binary and read from it via
a virtual file system. This also supports the `--node-modules-dir` flag,
dependencies specified in a package.json, and npm binary commands (ex.
`deno compile --unstable npm:cowsay`)
Closes #16632

Follow up to https://github.com/denoland/deno/pull/18875 that enables
`jemalloc` as a global allocator for the Deno CLI.
|
|
This removes `ProcState` and replaces it with a new `CliFactory` which
initializes our "service structs" on demand. This isn't a performance
improvement at the moment for `deno run`, but might unlock performance
improvements in the future.
|
|
1. Adds cli/standalone folder
2. Writes the bytes directly to the output file. When adding npm
packages this might get quite large, so let's not keep the final output
in memory just in case.
|
|
1. Breaks up functionality within `ProcState` into several other structs
to break out the responsibilities (`ProcState` is only a data struct
now).
2. Moves towards being able to inject dependencies more easily and have
functionality only require what it needs.
3. Exposes `Arc<T>` around the "service structs" instead of it being
embedded within them. The idea behind embedding them was to reduce the
verbosity of needing to pass around `Arc<...>`, but I don't think it was
exactly working and as we move more of these structs to be more
injectable I don't think the extra verbosity will be a big deal.
|
|
Removes the functions in the `emit` module and replaces them with an
`Emitter` struct that can have "ctor dependencies" injected rather than
using functions to pass along the dependencies.
This is part of a long term refactor to move more functionality out of
proc state.

Adds `--ext` to `deno run`, closes #5088
Additionally
- Adds `--ext` to `deno compile` and `deno bundle`
|
|
|
|
Makes the resolver required and prints a warning when vendoring and a
dynamic import can't be resolved.
Closes #16522
|
|
- Generalizes the npm version code (ex. `NpmVersion` -> `Version`,
`NpmVersionReq` -> `VersionReq`). This is a slow refactor towards
extracting out this code for deno specifiers and better usage in
deno_graph.
- Removes `SpecifierVersionReq`. Consolidates `NpmVersionReq` and
`SpecifierVersionReq` to just `VersionReq`
- Removes `NpmVersionMatcher`. This now just looks at `VersionReq`.
- Paves the way to allow us to create `NpmPackageReference`'s from a
package.json's dependencies/dev dependencies
(`VersionReq::parse_from_npm`).

Yearly tradition of creating extra noise in git.
|
|
Also adds download bytes progress when downloading remote specifiers.
Closes #16860

I'm not sure how to test this. It doesn't seem to have an existing test.
Closes #15921

1. Extracts out some code from main.rs
2. Inlines all the `x_command` functions in main.rs

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:
|
|
This is just a straight refactor and doesn't make any improvements to
the code that could now be made.
Closes #16493

cache folder (#16857)
|

|
|
|
|
|
|
This should be in the `args` folder as it's similar to `config_file`.
|
|
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.

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.
|
|
(#16637)
|
|
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.
|
|
These resolvers are used in `deno_graph` APIs. Combining them removes a
lot of code and
unblocks me on https://github.com/denoland/deno/pull/16157
|
|
Ensures that "std/node" graph is analyzed only once.
