26.0.50; tramp-test19-directory-files-and-attributes fails on 32-bit Cygwin |

Starting with commit 3a6df2d,
tramp-test19-directory-files-and-attributes fails on 32-bit Cygwin. The
reason is that inode numbers tend to be very large, on the order of
10^17, at least on my systems. As a result, the "convert inode" code in
tramp-convert-file-attributes always falls back to tramp-get-inode.
Since this increments by 1 on every call, the file-attribute comparisons
in tramp-test19-directory-files-and-attributes always fail.
The significance of commit 3a6df2d is that it makes
tramp-get-remote-stat return a non-nil value, so that tramp uses 'stat'
for file attributes; this returns the true (large) inode number. Prior
to that commit, tramp-get-remote-stat would always return nil, so that
the tramp-perl-file-attributes script would be used for file
attributes. This script uses whatever inode number is returned by
Perl's version of 'stat', which is presumably some sort of 32-bit
truncation of the true inode number.
Although I'm seeing this on 32-bit Cygwin, it seems to me that it could
in principle happen on any 32-bit platform.

That fixes it. Thanks.
I'm closing the bug.
