lineedit: histfile can get emptied when CONFIG_FEATURE_EDITING_SAVE_ON_EXIT=y
When CONFIG_FEATURE_EDITING_SAVE_ON_EXIT is set to y, the histfile will get cleared if the total amount of history lines is less than MAX_HISTORY. Only if the histfile is not empty _and_ the amount of lines currently in memory are equal to or greater than MAX_HISTORY, history saving will work as expected with this feature enabled. Output from defconfig + CONFIG_FEATURE_EDITING_SAVE_ON_EXIT=y: $ echo "foo" > ~/.ash_history $ ./busybox ash ~/busybox/a $ echo "bar" > /dev/null ~/busybox/a $ exit $ cat ~/.ash_history $ Output with the patch applied and same config as above: $ echo "foo" > ~/.ash_history $ ./busybox ash ~/busybox/b $ echo "bar" > /dev/null ~/busybox/b $ exit $ cat ~/.ash_history foo echo "bar" > /dev/null exit $ Signed-off-by: Dennis Groenen <tj.groenen at gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
