Hi!
It seems, that yaws 1.88 do not restarts. And that could be a stability
problem.
What I am doing:
Starting yaws, the command line is:
yaws --daemon --heart --heart-restart=0,0
Next I kill beam process.
kill <beam process ID>
But that kills the heart process, instead of beam process restarting.
Result is yaws death. I tried different --heart-restart=C,T, but yaws
never restarts. I remeber, that old version restarted well. How to force
restarts of new yaws? Or I'm doing something wrong?
Andrew

Works perfect for me too, Ubuntu Lucid Lynx.

Thanks all for reply!
The problem relates to additional parameter --erlarg .
(I thought it is irrelevant, but I was wrong).
Without --erlarg its works perfectly. But yaws does not restart with
--erlarg
this does not work:
yaws --daemon --heart --heart-restart=0,0 --erlarg "-env SOME_PATH
/home/user1"
and this works perfect:
yaws --daemon --heart --heart-restart=0,0
Sorry, I gave incomplete information before.
Andrew

Ok, clearly a bug, we'll look into it.
Thanks for reporting,

Did a bit of debugging here, first off a trick that some of you
may need in future debugging sessions, I added:
exec 3>&1 4>&2 >$HOME/tmp/cap.$$ 2>&1
To the top of the yaws script, thus redirecting script output from
within the script itself
It turns out that the quotes are dropped on the second invocation, thus
yaws --daemon --heart --heart-restart=0,0 --erlarg "-env SOME_PATH /home/user1"
becomes,
yaws --daemon --heart --heart-restart=0,0 --erlarg -env SOME_PATH /home/user1
making yaws reject the command line.
I see no real good way out of this, maybe some clever /bin/sh wizard on
the list knows better. I'm dropping this, you'll have to solve this some other
way.
Sorry,
/klacke

This is good debug info, so I'll try to pick up the debugging from here.

But it's not really a yaws issue any longer, it's erl -heart and quoted args
that don't work too well together. Solving it is hard/impossible at least
with the same set of flags.

OK, thanks for checking it; I've now pushed it up to github. This
solution will work for the case you provided, which is very very much
the normal case, but if anyone ever wanted to pass something like
--erlargs "-env NAME O'Keeffe"
where the name or value contains a single quote, it will still fail.
This case and the case where either name or value contains a double
quote are also fixable, but I figured they'd be so rare they're not
worth cluttering the code to handle them.
