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.

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.

There were still remaining bigint usages for pointers. This now finally
fixes all of them, there is only the one `type PointerValue = number |
bigint;` line that references `bigint` in the unstable type definition
file.
Potential fix for type-code mismatch in FFI buffer types. The code
supports ArrayBuffers, but types only reflect TypedArray support.
There's also an existing type for this sort of stuff: `BufferSource`.
(Although, it uses `ArrayBufferView` which doesn't actually connect with
the TypedArray interfaces specifically, but it's just a type inheritance
difference and nothing more.)

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.
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.
