Patrick Palka 948578a989 tui: don't overwrite a secondary prompt that was given no input ... This patch fixes the following bug in TUI: (gdb) break foo No symbol table is loaded. Use the "file" command. Make breakpoint pending on future shared library load? (y or [n]) <ENTER> By submitting an empty command line to a secondary prompt, the line corresponding to the secondary prompt is undesirably cleared and overwritten. Outside of a secondary prompt, clearing the prompt line after submitting an empty command line is intended behavior which complements GDB's repeat-command shorthand. But inside a secondary prompt, this behavior is undesired since the shorthand is not applicable in that case. We should retain the secondary-prompt line even when it's given no input. This patch makes sure that a prompt that was given an empty command line is cleared and overwritten only if it's not a secondary prompt. To acheive this, a new predicate is defined which informs us whether the current input handler is a secondary prompt. gdb/ChangeLog: * top.h (gdb_in_secondary_prompt_p): Declare. * top.c (gdb_secondary_prompt_depth): Define. (gdb_in_secondary_prompt_p): Define. (gdb_readline_wrapper_cleanup): Decrement gdb_secondary_prompt_depth. (gdb_readline_wrapper): Increment gdb_secondary_prompt_depth. * tui/tui-io.c (tui_getc): Don't clear the prompt line if we are in a secondary prompt.		2015-08-21 16:18:39 -04:00
