Title:
deal with EPIPE from json hooks

Bug description:
[Impact]
json hooks ending with EPIPE on first read fail, but should simply do
nothing. This causes spurious failures of uninstalled hooks.
Also, there is a missing error exit, causing errors reported by the
script to not exit.
[Test case]
For the first part, I cannot generate one. This was discovered by snapd ci,
but I did not find a reproducer yet.
FWIW, the change should be tiny enough to see that it is not wrong:
- if (errno != ECONNRESET)
+ if (errno != ECONNRESET && errno != EPIPE)
_error->Error("Could not read response to hello message from hook
%s: %s", Opts->Value.c_str(), strerror(errno));
The missing error handling is the next lines:
else if (strstr(line, "error") != nullptr)
{
_error->Error("Hook %s reported an error during hello: %s",
Opts->Value.c_str(), line);
+ goto out;
}
that can be checked:
sudo apt -o AptCli::Hooks::Install::="/usr/bin/printf '{error should
be json}\n\n' >&3" install
[Regression potential]
JSON hooks failures with EPIPE are now ignored, so if it fails with EPIPE for
other reasons than just exiting, I guess we might miss it
