* kconfig: adapt update-po-config to new UML layoutPaul Bolle2011-12-181-3/+2
| | | | | | | | | | | | | | Commit 5c48b108 ("um: take arch/um/sys-x86 to arch/x86/um") broke the make target update-po-config, as its symlink trick (again) fails. (Previous breakage was fixed with commit bdc69ca4 ("kconfig: change update-po-config to reflect new layout of arch/um").) The new UML layout allows to drop the symlick trick entirely. And if, one day, another architecture supports UML too, that should now work without again breaking this make target.

* scripts/kconfig/nconf: fix editing long stringsCheng Renquan2011-09-091-6/+23
| | | | | | | | | | | | | | The original dialog_inputbox doesn't work with longer than prompt_width strings, here fixed it in this way: 1) add variable cursor_form_win to record cursor of form_win, keep its value always between [0, prompt_width-1]; reuse the original cursor_position as cursor of the string result, use (cursor_position-cursor_form_win) as begin offset to show part of the string in form_win; Signed-off-by: Cheng Renquan <crquan@gmail.com> Cc: Arnaud Lacombe <lacombar@gmail.com> Cc: Nir Tzachar <nir.tzachar@gmail.com>

This patch changes the logic in menu_get_ext_help to display help for cases which dont have symbol names like choice.

This leads to a NULL pointer dereference when an empty menu is encountered. The following reduced testcase exposes the problem: config DEP bool menu "FOO" config BAR bool "BAR" depends on DEP endmenu Issue will happen when entering menu "FOO" and requesting help. nconf is the only front-end which do not filter the validity of the current menu. Such filter can not really happen beforehand as other key which does not deals with the current menu might be entered by the user, so just bails out earlier if we encounter an invalid menu.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nconf is the only front-end which does not use this helper, but prefer to copy/paste the code. The test wrt. menu validity added in this version of the code is bogus anyway as an invalid menu will get dereferenced a few line below by calling menu_get_prompt(). For now, convert nconf to use menu_get_ext_help(), as do every other front-end. We will deals with menu validity checks properly in a separate commit.
