2009-03-22libbb: make history saving/loading concurrent-safeDenis Vlasenko
* all history writers always append (not overwrite) history files * they reload history if they detect that file length has changed since last write * they trim history file only when it grows 4 times longer than MAXLINES * they do this atomically by creating new file and renaming it to old Unfortunately, this comes at a price: function old new delta load_history - 346 +346 read_line_input 3155 3358 +203 new_line_input_t 17 31 +14 ...irrelevant small jitter... ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 5/5 up/down: 573/-13) Total: 560 bytes

2008-01-18eliminated CONFIG_FEATURE_EDITING_FANCY_KEYS. the size savingsPaul Fox
was small, compared to the total size of the command-line editing features, and it removed key bindings that most wouldn't consider "fancy", like ^U, and 'l' and 'h' in vi mode, ^F and ^B in emacs mode.
2008-01-11enable use of ^V prefix to allow forced insertion of any character. inPaul Fox
particular, without this it's impossible to enter a TAB on the commandline (whether tab completion is enabled or not).
