Actually give useful error messages if executing git remote helper fails
for some reason.
The previous error message was:
git: 'remote-fail' is not a git-command. See 'git --help'
This changes the error message to:
'Unable to find remote helper for "nonexistent"'
or
'Unable to run helper HelperThatGetsEACCESS: Permission denied'
(or whatever the errno is).
Patch series is based on v1.6.6.
One of the changes is adjacent to changes in external helper dispatch
support change and gets merge conflict. Here's how I resolved that
conflict for testing:
helper->argv[2] = remove_ext_force(transport->url);
helper->git_cmd = 0;
if (start_command(helper)) {
if (errno == ENOENT)
die("Unable to find remote helper for \"%s\"",
data->name);
else
die("Unable to run helper %s: %s", helper->argv[0],
strerror(errno));
}
The first line in that comes from dispatch support and the rest come from
exec failure reporting.
