XuNeo opened a new pull request, #14921: URL: https://github.com/apache/nuttx/pull/14921
*Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* ## Summary 1. For diagnose command, we catch any gdb error happened and report it in the final message. 2. Fix thread command not working on come circumstances. `thread` is a GDB prefix command. Use `define` can only change it to a user prefix command. In this case, `thread 3` is unable to pass the argument 3 to python. Use python code to register command to overwrite this behavior. It may not work with future GDB, but all is good for now. 3. Optimize `memleak` command by caching the global variables information parsed from elf file. This can save seconds when run the command for multiple times. ## Impact *Update this section, where applicable, on how change affects users, build process, hardware, documentation, security, compatibility, etc.* ## Testing Tested with qemu arm64. The thread command can work correctly. ``` (gdb) info threads Index Tid Pid Cpu Thread Info Frame *0 0 0 0 '\000' Thread 0x404345e0 (Name: CPU0 IDLE, State: Running, Priority: 0, Stack: 16368) 0x402b1bcc pl011_rxavailable() at /home/neo/projects/nuttx/nuttx/drivers/serial/uart_pl011.c:697 *1 1 0 1 '\001' Thread 0x40434738 (Name: CPU1 IDLE, State: Running, Priority: 0, Stack: 16368) 0x402b1bcc pl011_rxavailable() at /home/neo/projects/nuttx/nuttx/drivers/serial/uart_pl011.c:697 2 2 0 0 '\000' Thread 0x4044a000 (Name: hpwork, State: Waiting,Semaphore, Priority: 192, Stack: 16304) 0x402c32c0 nxsem_wait() at /home/neo/projects/nuttx/nuttx/sched/semaphore/sem_wait.c:213 3 3 3 1 '\001' Thread 0x4044e210 (Name: nsh_main, State: Waiting,Semaphore, Priority: 100, Stack: 16336) 0x402c32c0 nxsem_wait() at /home/neo/projects/nuttx/nuttx/sched/semaphore/sem_wait.c:213 (gdb) info nxt Index Tid Pid Cpu Thread Info Frame *0 0 0 0 '\000' Thread 0x404345e0 (Name: CPU0 IDLE, State: Running, Priority: 0, Stack: 16368) 0x402b1bcc pl011_rxavailable() at /home/neo/projects/nuttx/nuttx/drivers/serial/uart_pl011.c:697 *1 1 0 1 '\001' Thread 0x40434738 (Name: CPU1 IDLE, State: Running, Priority: 0, Stack: 16368) 0x402b1bcc pl011_rxavailable() at /home/neo/projects/nuttx/nuttx/drivers/serial/uart_pl011.c:697 2 2 0 0 '\000' Thread 0x4044a000 (Name: hpwork, State: Waiting,Semaphore, Priority: 192, Stack: 16304) 0x402c32c0 nxsem_wait() at /home/neo/projects/nuttx/nuttx/sched/semaphore/sem_wait.c:213 3 3 3 1 '\001' Thread 0x4044e210 (Name: nsh_main, State: Waiting,Semaphore, Priority: 100, Stack: 16336) 0x402c32c0 nxsem_wait() at /home/neo/projects/nuttx/nuttx/sched/semaphore/sem_wait.c:213 (gdb) t 3 (gdb) bt #0 nxsem_wait (sem=sem@entry=0x40428588 <g_uart1port+40>) at /home/neo/projects/nuttx/nuttx/sched/semaphore/sem_wait.c:213 #1 0x00000000402b2f40 in uart_read (filep=0x4044e708, buffer=0x404527af "", buflen=1) at ...
