How about this instead? -- >8 -- Fix git-am safety checks An earlier commit cbd64af added a check that prevents "git-am" to run without its standard input connected to a terminal while resuming operation. This was to catch a user error to try feeding a new patch from its standard input while recovery. The assumption of the check was that it is an indication that a new patch is being fed if the standard input is not connected to a terminal. It is however not quite correct (the standard input can be /dev/null if the user knows the operation does not need any input, for example). This broke t3403 when the test was run with its standard input connected to /dev/null. When git-am is given an explicit command such as --skip, there is no reason to insist that the standard input is a terminal; we are not going to read a new patch anyway. Credit goes to Gerrit Pape for noticing and reporting the problem with t3403-rebase-skip test. --- diff --git a/git-am.sh b/git-am.sh index d0af786..66a8e3d 100755 --- a/git-am.sh +++ b/git-am.sh @@ -166,10 +166,25 @@ fi if test -d "$dotest" then - if test ",$#," != ",0," || ! tty -s - then - die "previous dotest directory $dotest still exists but mbox given." - fi + case "$#,$skip$resolved" in + 0,*t*) + # Explicit resume command and we do not have file, so + # we are happy. + : ;; + 0,) + # No file input but without resume parameters; catch + # user error to feed us a patch from standard input + # when there is already .dotest.
