Tue Nov 21 07:04:06 UTC 2023 - Dr. Werner Fink <werner@suse.de>
- Add upstream patch readline82-002
* It's possible for readline to try to zero out a line that's not null-
terminated, leading to a memory fault.
- Add upstream patch readline82-003
- Add upstream patch readline82-004
- Add upstream patch readline82-005
* 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.
- Add upstream patch readline82-006
* This is a variant of the same issue as the one fixed by patch 5. In this
case, the signal arrives and is pending before readline calls rl_getc().
When this happens, the pending signal will be handled by the loop, but may
alter or destroy some state that the callback uses. Readline needs to treat
this case the same way it would if a signal interrupts pselect/select, so
compound operations like searches and reading numeric arguments get cleaned
up properly.
- Add upstream patch readline82-007
* If readline is called with no prompt, it should display a newline if return
is typed on an empty line. It should still suppress the final newline if
return is typed on the last (empty) line of a multi-line command.
