Force core.filemode to false on Cygwin.
Many users have noticed that core.filemode doesn't appear to be automatically set right on Cygwin when using a repository stored on NTFS. The issue is that Cygwin and NTFS correctly supports the executable mode bit, and Git properly detected that, but most native Windows applications tend to create files such that Cygwin sees the executable bit set when it probably shouldn't be. This is especially bad if the user's favorite editor deletes the file then recreates it whenever they save (vs. just overwriting) as now a file that was created with mode 0644 by checkout-index appears to have mode 0755. So we introduce NO_TRUSTABLE_FILEMODE, settable at compile time. Setting this option forces core.filemode to false, even if the detection code would have returned true. This option should be enabled by default on Cygwin. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
