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.
Run benchmarks on a bare metal server. The bot is a webhook on Deno
deploy which can provision a spot instance on Equinix Metal. The machine
type is `m3.small.x86` running a Ubuntu 22.04.
Commands:
`+bench` - Provision and schedule benchmarks for this PR.
`+bench status <id>` - Get current status of the metal instance.
The bot source is here: https://github.com/denoland/bench_bot
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.
>
> To opt out, developers can add an `|| exit 0`:
>
> ```jsonc
> "dev": "deno task server || exit 0 & deno task frontend:watch"
> ```

This commit removes the calls to `expect()` on `std::rc::Rc`, which caused
Deno to panic under certain situations. We now return an error if `Rc`
is referenced by other variables.

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`.
closes #8852
Fixes the error reported in #16304.
> = note:
/usr/bin/ld:/home/abotella/Projects/deno/cli/generated_symbol_exports_list_linux.def:1:
syntax error in dynamic list
collect2: error: ld returned 1 exit status
This was caused by the format of the symbols list on Linux being
malformed (as the error implies).
The format is documented in ld's
[VERSION](https://sourceware.org/binutils/docs/ld/VERSION.html) as well
as:
> --export-dynamic-symbol-list=file
Specify a --export-dynamic-symbol for each pattern in the
file. The format of the file is the same as the version node
without scope and node name. See VERSION for more
information.
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 };
```
It crashes due to the table border output from `strace`,
```
% time seconds usecs/call calls errors syscall
------ ----------- ----------- --------- --------- ---------------- # this is skipped correctly
61.27 6.012053 678 8860 637 futex
0.00 0.000000 0 4 geteuid
------ ----------- ----------- --------- --------- ---------------- # this causes the crash
100.00 11.732230 25552 1205 total
```
It's flaky because that line is not always skipped from the output, for
some reason that I've yet to find out.
This adds an implementation of `Default` for both `WorkerOptions` and
`BootstrapOptions`. Since both of these structs are rather big, this
should make it easier for people unfamiliar with the internals to focus
on the options relevant to them.
As a user of `deno_runtime` I feel like these should serve as good
defaults, getting people them started without having to tweak the
runtime. Additionally even if some changes are made, the usage of
`..Default::default()` will significantly help with code clarity and
verbosity.
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.
