This commit changes how "disabled" ops behave. Instead of using "void"
functions under the hood, they now explicitly throw errors saying
that a given op doesn't exist.
|
|
With https://github.com/denoland/deno/pull/18568 landed we no longer
need "ext/flash".
This commit removes "deno_flash" extension completely.
This should have some impact on the binary and snapshot size.
Closes https://github.com/denoland/deno/issues/17356

Relanding 4b6305f4f25fc76f974bbdcc9cdb139d5ab8f5f4
|
|
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:

Closes https://github.com/denoland/deno/issues/2347
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
}
