Subject: [PATCH 2/8] [lldb-dap] Added "port" property to vscode "attach"
command.
Adding a "port" property to the VsCode "attach" command likely extends the
functionality of the debugger configuratiuon to allow attaching to a process
using PID or PORT number.
Currently, the "Attach" configuration lets the user specify a pid. We tell the
user to use the attachCommands property to run "gdb-remote <port>".
Followed the below conditions for "attach" command with "port" and "pid"
We should add a "port" property. If port is specified and pid is not, use that
port to attach. If both port and pid are specified, return an error saying that
the user can't specify both pid and port.
Ex - launch.json
{
"version": "0.2.0",
"configurations": [
{
"name": "lldb-dap Debug",
"type": "lldb-dap",
"request": "attach",
"port":1234,
"program": "${workspaceFolder}/a.out",
"args": [],
"stopOnEntry": false,
"cwd": "${workspaceFolder}",
"env": [],
}
]
}

Currently, the "Attach" configuration lets the user specify a pid. We tell the

We should add a "port" property. If port is specified and pid is not, use that
port to attach. If both port and pid are specified, return an error saying that
the user can't specify both pid and port.
Ex - launch.json
{
"version": "0.2.0",

"program": "${workspaceFolder}/a.out",
"args": [],
"stopOnEntry": false,
"cwd": "${workspaceFolder}",
"env": [],
}
]
}
In this patch we have resolved code formatting issues and fixed "test_by_name"
failure.
