[lldb-dev] Question on SetAsync(False) Mode

[Yin Ma]

Hi Enrico and Jim,

 

My lldb is 179.5 on mountain lion

 

What I did for the good result

File “xxx”

B main

R

Program stops at breakpoint and print thread and frame information.

 

For bad result

File “xxx”

B main

Command script import a.py

R

Process 10786 launched: ‘xxx’ (x86_64)

 

In the a.py

Def __lldb_init_module (debugger, dict):

      Debugger.SetAsync(False)

 

This is about what I did.

 

Thanks,

 

Yin

First of all the obvious

Have you checked that your breakpoint is getting hit at all?

For instance, did you manually run lldb, set the breakpoint, and then run, and watch LLDB actually stop there?

If not, it seems a worthy initial test

 

If that works, more repro steps might be necessary to figure this out.

What inferior are you using? What does your script do exactly? That kind of information

Hello,

What I want is to run a command and return to lldb only after
This command finishes. This should be the behavior of 
synchronous mode. So I called 
debugger.SetAsync(False) 
right after lldb starts. However, I never get what
I expected. I set breakpoint and run. The process
Never stops, it just shows process exited.

Based on the webpage, it says:
When we step or continue, don't return from the function
Until the process stops. 
So, when process stops at breakpoints, it should return
To lldb. Now it doesn't. 

Is this the right behavior? How I can get the behavior
I want?

Thanks,

Yin
