Bug-Description:
|
|
If an application is using readline in callback mode, and a signal arrives
|
after readline checks for it in rl_callback_read_char() but before it
|
restores the application's signal handlers, it won't get processed until the
|
next time the application calls rl_callback_read_char(). Readline needs to
|
check for and resend any pending signals after restoring the application's
|
signal handlers.
