gdb-command
gdb-command
is a library providing API for manipulating gdb in batch mode. It supports:
- Execution of target program (Local type).
- Opening core of target program (Core type).
- Attaching to remote process (Remote type).
Example
use std::process::Command;
use std::thread;
use std::time::Duration;
use gdb_command::*;
fn main () -> error::Result<()> {
// Get stacktrace from running program (stopped at crash)
let result = GdbCommand::new(&ExecType::Local(&["tests/bins/test_abort", "A"])).bt().run()?;
// Get stacktrace from core
let result = GdbCommand::new(
&ExecType::Core {target: "tests/bins/test_canary",
core: "tests/bins/core.test_canary"})
.bt().run()?;
// Get info from remote attach to process
let mut child = Command::new("tests/bins/test_callstack_remote")
.spawn()
.expect("failed to execute child");
thread::sleep(Duration::from_millis(10));
// To run this test: echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
let result = GdbCommand::new(&ExecType::Remote(&child.id().to_string()))
.bt()
.regs()
.disassembly()
.run();
child.kill().unwrap();
Ok(())
}
