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.

/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.
The return type checking for `"function"` type FFI values was incorrect
and presumed that functions were still being registered as objects
containing a "function" key.
While here, I also removed the whole return type checking logic as it
was needed for optionally creating BigInts on return when needed, but
serde_v8 does this automatically now (I think).
This commit prevents panics that `deno compile` command ran into under certain
conditions from occurring. Such conditions are as follows.
- the target file name begins with `@`, OR
- the stem part of the target file name is equal to one of
["main", "index", "mod", "index"] && the parent directory name starts with `@`
Fixes #16243
This PR fixes invalid header parsing which is flaky because `g` flag is
being used in the regex, which keeps track of `lastIndex`
```javascript
try {
new Headers([["x", "\u0000x"]]); // error
} catch(e) {}
new Headers([["x", "\u0000x"]]); // no error
```
This issue affects `Response` & `Request` constructors as well
This commit adds a new op_write_all to core that allows writing an
entire chunk in a single async op call. Internally this calls
`Resource::write_all`.
The `writableStreamForRid` has been moved to `06_streams.js` now, and
uses this new op. Various other code paths now also use this new op.
Closes #16227
Changes introduced in #13633 have broken the ability to compile for
linux/aarch64 - specifically the use of a `i8` as a char type, which is
an `u8` on linux/aarch64.
This PR:
- Replaces instances of `i8` with the architecture-aware wrapper type
`c_char`
- Skips the use of `--export-dynamic-symbol` on linux-aarch64, because
the target environments often rely on older libc/binutils versions
This commit introduces two new buffer wrapper types to `deno_core`. The
main benefit of these new wrappers is that they can wrap a number of
different underlying buffer types. This allows for a more flexible read
and write API on resources that will require less copying of data
between different buffer representations.
- `BufView` is a read-only view onto a buffer. It can be backed by
`ZeroCopyBuf`, `Vec<u8>`, and `bytes::Bytes`.
- `BufViewMut` is a read-write view onto a buffer. It can be cheaply
converted into a `BufView`. It can be backed by `ZeroCopyBuf` or
`Vec<u8>`.
Both new buffer views have a cursor. This means that the start point of
the view can be constrained to write / read from just a slice of the
view. Only the start point of the slice can be adjusted. The end point
is fixed. To adjust the end point, the underlying buffer needs to be
truncated.
Readable resources have been changed to better cater to resources that
do not support BYOB reads. The basic `read` method now returns a
`BufView` instead of taking a `ZeroCopyBuf` to fill. This allows the
operation to return buffers that the resource has already allocated,
instead of forcing the caller to allocate the buffer. BYOB reads are
still very useful for resources that support them, so a new `read_byob`
method has been added that takes a `BufViewMut` to fill. `op_read`
attempts to use `read_byob` if the resource supports it, which falls
back to `read` and performs an additional copy if it does not. For
Rust->JS reads this change should have no impact, but for Rust->Rust
reads, this allows the caller to avoid an additional copy in many
scenarios. This combined with the support for `BufView` to be backed by
`bytes::Bytes` allows us to avoid one data copy when piping from a
`fetch` response into an `ext/http` response.
Writable resources have been changed to take a `BufView` instead of a
`ZeroCopyBuf` as an argument. This allows for less copying of data in
certain scenarios, as described above. Additionally a new
`Resource::write_all` method has been added that takes a `BufView` and
continually attempts to write the resource until the entire buffer has
been written. Certain resources like files can override this method to
provide a more efficient `write_all` implementation.
This commit fixes one ocurrence of unsoundness by using the newly added
API (`v8::String::write_utf8_uninit`).

Note that it is not actually a bug. Avoiding unsoundness improves our
code quality.
