If the name of the file being written doesn't match the current filename and the output file already exists vi should issue a warning and not overwrite the file.
Because the test only compares the file names it's somewhat over- protective. If the current file name is 'my_text' and the user tries to save to './my_text' they'll be prevented from doing so. function old new delta colon 3092 3151 +59 .rodata 105118 105146 +28 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 87/0) Total: 87 bytes Signed-off-by: Ron Yorston <[email protected]> --- editors/vi.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/editors/vi.c b/editors/vi.c index ccf2870ab..47b13b3ca 100644 --- a/editors/vi.c +++ b/editors/vi.c @@ -2816,6 +2816,13 @@ static void colon(char *buf) // is there a file name to write to? if (args[0]) { + struct stat statbuf; + + if (!useforce && (fn == NULL || strcmp(fn, args) != 0) && + stat(args, &statbuf) == 0) { + status_line_bold("File exists (:w! overrides)"); + goto ret; + } fn = args; } # if ENABLE_FEATURE_VI_READONLY -- 2.30.2 _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
