MongoDB client failed to use connectionURL containing an IPv6 host

[guyutongxue]

For example:

DATABASE_URL='mongodb://[2605:340:c0ff:eeab:be::a25a]:27017/myDatabase' npx prisma db push

Results

Error: P1013

The provided database string is invalid. An invalid argument was provided: address "[2605:340:c0ff:eeab:be::a25a]:27017" contains more than one unescaped ':' in database URL. Please refer to the documentation in https://www.prisma.io/docs/reference/database-reference/connection-urls for constructing a correct connection string. In some cases, certain characters must be escaped. Please check the string for any illegal characters.

And the buggy code is

Lines 140 to 185 in 46b8397

	let mut parts = address.split(':');
	let hostname = match parts.next() {
	Some(part) => {
	if part.is_empty() {
	return Err(ErrorKind::invalid_argument(format!(
	"invalid server address: \"{address}\"; hostname cannot be empty"
	))
	.into());
	}
	part
	}
	None => {
	return Err(
	ErrorKind::invalid_argument(format!("invalid server address: \"{address}\"")).into(),
	);
	}
	};
	let port = match parts.next() {
	Some(part) => {
	let port = u16::from_str(part).map_err(|_| {
	ErrorKind::invalid_argument(format!(
	"port must be valid 16-bit unsigned integer, instead got: {part}"
	))
	})?;
	if port == 0 {
	return Err(ErrorKind::invalid_argument(format!(
	"invalid server address: \"{address}\"; port must be non-zero"
	))
	.into());
	}
	if parts.next().is_some() {
	return Err(ErrorKind::invalid_argument(format!(
	"address \"{address}\" contains more than one unescaped ':'"
	))
	.into());
	}
	Some(port)
	}
	None => None,
	};
	Ok((hostname.to_lowercase(), port))

which just split the hostname by :... and definitely wrong for IPv6 address.
