Permission denied error when running git in 64-bit CYGWIN console

Permission denied error when running git in 64-bit CYGWIN console

[John J Ottusch]

The transition from 32-bit CYGWIN (C32) to 64-bit CYGWIN (C64) has been 
mostly smooth, but I have encountered some unexpected difficulties. The 
latest involves 'git' version 2.5.3.

When I run 'git difftool' from my project directory in a C32 console I 
get the expected behavior, but doing the same in a C64 console produces 
the error

	fatal: cannot exec 'git-difftool': Permission denied
	
It has been suggested that git generates this error because of an 
inaccessible directory in my $PATH. All the directories check out as 
accessible from the account I am logged in to. Furthermore, logging into 
an account with administrator privileges makes no difference. Even 
reducing my $PATH to /usr/bin makes no difference. I also checked out 
all the mount points.

I have also read that running

	strace -f -e execve git difftool
	
can help find the $PATH entry that is returning EACCES. But that just 
returns the error

	strace.exe: error creating process execve, (error 2)

Running the same command without execve produces debugging output but 
does not reveal to me the source of the permission denied error.

I note that the problem is apparently related to 'git difftool' invoking 
the git alias 'git-difftool' since 'git diff' works fine.

Any help fixing or debugging this problem would be appreciated.

Git is at version 2.6.2 in Cygwin at the moment, so whatever problem you
have with version 2.5.3 might clear up once you have updated Cygwin
fully.

Achim,

Updating my 64-bit CYGWIN installation to the latest release (as of 
today), which includes git version 2.6.2, did in fact solve the problem I 
was experiencing.

Thanks,

jjo
