This reverts commit 4b6305f4f25fc76f974bbdcc9cdb139d5ab8f5f4.
|
|
This commit changes the build process in a way that preserves already
registered ops in the snapshot. This allows us to skip creating hundreds of
"v8::String" on each startup, but sadly there is still some op registration
going on startup (however we're registering 49 ops instead of >200 ops).
This situation could be further improved, by moving some of the ops
from "runtime/" to a separate extension crates.

Follow-up to #18210:
* we are passing the generated `cfg` object into the state function
rather than passing individual config fields
* reduce cloning dramatically by making the state_fn `FnOnce`
* `take` for `ExtensionBuilder` to avoid more unnecessary copies
* renamed `config` to `options`
|
|
(#18210)
This implements two macros to simplify extension registration and centralize a lot of the boilerplate as a base for future improvements:
* `deno_core::ops!` registers a block of `#[op]`s, optionally with type
parameters, useful for places where we share lists of ops
* `deno_core::extension!` is used to register an extension, and creates
two methods that can be used at runtime/snapshot generation time:
`init_ops` and `init_ops_and_esm`.

raw mode (#17983)
|
|
There's no point for this API to expect result. If something fails it should
result in a panic during build time to signal to embedder that setup is
wrong.
|
|
This commit factors out APIs related to file system from "runtime/"
to a separate "deno_fs" extension crate.
|
|
This is to allow making assertions on stdout and stderr separately.
|
|
This commit merges "runtime/js/40_spawn.js" into
"runtime/js/40_process.js", and "runtime::ops::spawn"
into "runtime::ops::process".
It makes little sense to have them separated given that we want to
factor out these APIs into a separate extension crate.
|
|
This is a prerequisite to factor out FS ops to a separate crate.
|
|
This utility is useful in several contexts so it seems reasonable to
have it in `deno_core`.
|
|
This will help us with moving fs ops to a separate extension crate.

Reland https://github.com/denoland/deno/pull/16777
The codegen is disabled in async ops and when fallback to slow call is
possible (return type is a Result) to avoid hitting this V8 bug:

Uses unstable rustfmt features. Since dprint invokes `rustfmt` we do not
need to switch the cargo toolchain to nightly. Do we care about
formatting stability of our codebase across Rust versions? (I don't)

mutability (#17134)
Turns out we were cloning permissions which after prompting were discarded,
so the state of permissions was never preserved. To handle that we need to store
all permissions behind "Arc<Mutex<>>" (because there are situations where we
need to send them to other thread).
Testing and benching code still uses "Permissions" in most places - it's undesirable
to share the same permission set between various test/bench files - otherwise
granting or revoking permissions in one file would influence behavior of other test
files.

This PR adds support for `Deno.osUptime` which reports number of seconds
since os was booted. It will allow us to be compatible with Node's `os.uptime` -
https://nodejs.org/api/os.html#osuptime
Partially based on
https://docs.rs/uptime_lib/latest/src/uptime_lib/lib.rs.html
|
|
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.

This commit removes three unstable Deno APIs:
- "Deno.spawn()"
- "Deno.spawnSync()"
- "Deno.spawnChild()"
These APIs were replaced by a unified "Deno.Command" API.

Uses SeqOneByteString optimization to do zero-copy `&str` arguments in
fast calls.
- [x] Depends on https://github.com/denoland/rusty_v8/pull/1129
- [x] Depends on
https://chromium-review.googlesource.com/c/v8/v8/+/4036884
- [x] Disable in async ops
- [x] Make it work with owned `String` with an extra alloc in fast path.
- [x] Support `Cow<'_, str>`. Owned for slow case, Borrowed for fast
case
```rust
#[op]
fn op_string_len(s: &str) -> u32 {
str.len() as u32
}

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
