For the past few weeks "make check" has been taking a looooong time on
Emacs master on my Fedora 27 desktop (AMD Phenom II X4 910e). The first
line of "make" output that causes a long delay is:
GEN lisp/net/tramp-tests.log
and some of the tests in the corresponding script look to be very slow.
Can this be sped up? Let's mark the slow tests to be expensive, so that
they are run only if one executes "make check-expensive".
Worse, there's another long wait here:
GEN lisp/net/tramp-archive-tests.log
after this line is output:
passed 20/22 tramp-archive-test40-file-system-info
and here the wait is so long that I gave up trying to run the tests and
typed control-C to exit them. Presumably the semi-inflooping test is
tramp-archive-test42-auto-load. (Why is it 42 and not 41? Why are there
two test42s? I don't know.)
Worse yet, after I control-C out of "make check" and get a shell prompt
back, a subsidiary Emacs that is running the Tramp test refuses to exit
and continues to chew up CPU time in the background until I use "kill
3304" (or whatever) to kill it. This really needs to get fixed.
Because of these problems I no longer routinely run "make check".
