2012-04-26lineedit: histfile can get emptied when CONFIG_FEATURE_EDITING_SAVE_ON_EXIT=yDennis Groenen
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>

2010-11-22lineedit: fix tab-completion of filenames with spacesMike Shal
Using ash in busybox git version dea28e1e, tab completion doesn't seem to work properly for filenames that have special characters (such as spaces) in them. For example, with filenames "foo bar" and "foo zap", typing "ls fo<TAB>" correctly expands to "ls foo\ ", but then continuing to type "b<TAB>" will produce "ls foo\ bbar", which is not correct (the 'b' is duplicated).
