Ron Yorston	a2fd1aaf86	vi: allow manual screen update if SIGWINCH isn't supported ... On platforms that don't support SIGWINCH vi can be configured with FEATURE_VI_USE_SIGNALS disabled and FEATURE_VI_WIN_RESIZE enabled. This allows the user to force an update with ^L when the screen is resized. However, because the SIGWINCH handler hasn't run the virtual screen buffer won't have been updated and the display becomes corrupted. Fix this by calling new_screen() if necessary.

Ron Yorston	61052d1bb8	vi: further fixes to undo after autoindent ... Commit bb983f30e (vi: fix faulty undo after autoinsert) has a number of problems: - The commit message refers to 'autoinsert' when it really means 'autoindent'. - The indentation of undo_push_insert() was incorrect. - Most seriously the commit only fixed the problem for cases where the indentation was exactly one character. This is because undo_push() only allows single characters to be queued for UNDO_INS_QUEUED. Lifting this restriction allows the example given in the previous commit message (with a three character indent) to work. function old new delta undo_push 406 435 +29 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 29/0) Total: 29 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2019-02-11 11:47:20 +01:00

Ron Yorston	d08206dce1	vi: correctly detect when a deletion empties the buffer ... Michał Berger has reported two issues: - Repeatedly deleting and undoing the deletion of the last line results in characters being lost from the end of the line. - Deleting the bottom line twice then attempting to undo each of these deletions results in a segfault. The problem seems to be an incorrect test for whether the text buffer is empty.

It was changed with commit "32afd3a vi: some simplifications" which happened before 1.23.0. Mistyping filename on command line happens fairly often and it's better we restore the old behaviour to avoid a few unnecessary flash writes and sometimes efforts of debugging bugs caused by those unneeded stray files.

Paul Fox	2724fa9d8a	remove alarm() calls which were functioning as a primitive ... watchdog function, presumably to catch infinite loop bugs. (control-C can do the same thing, and the alarms were too short in any case.) also, switch to sigsetjmp/siglongjmp in order to allow repeated use of control-C -- otherwise it works once, then not again.	2008-03-17 15:28:07 +00:00
