[issue12861] PyOS_Readline uses single lock

Well, readline is supposed to be used with a console, and there is only one 
usually.  Why would you want to use readline from multiple threads?

You might have opened several via `openpty`.

I am doing that here: https://github.com/albertz/PyTerminal

[issue12861] PyOS_Readline uses single lock

2011-08-31 Thread Albert Zeyer 

Albert Zeyer alb...@googlemail.com added the comment:

Even more problematic: The readline lib itself is absolutely not designed in a 
way to be used from multi threads at once.

[issue12861] PyOS_Readline uses single lock

2011-08-30 Thread Albert Zeyer 

New submission from Albert Zeyer alb...@googlemail.com:

In Parser/myreadline.c PyOS_Readline uses a single lock (`_PyOS_ReadlineLock`). 
I guess it is so that we don't have messed up stdin reads. Or are there other 
technical reasons?

However, it should work to call this function from multiple threads with 
different/independent `sys_stdin` / `sys_stdout`.

Ok, it seems that the Modules/readline.c implementation is also not really 
threadsafe... (Whereby, I think it should be.)
