memcached(8) loosing fd events...

[John McCaskey]

Ok, so I fixed that error in php-mcache, but libmemcache seems to have
an infinite loop of trying to do mcm_server_connect over and over when
my server is down.

I am setting the server to localhost on an invalid port, then doing a
mcm_set, this causes an infinite loop of connection attempts
immediately.  I think this should be trivial to reproduce, let me know
if you can't.  Thanks.

FYI, It's because I'm not calling McMemNewCtxt, I'm defining a ctx
struct, not a pointer, then just calling the setup function... which
used to be ok, but now its not since it needs to allocate mem for the
err ctxt within the main ctxt.

You're probably missing this:

  MCM_ERR_INIT_CTXT(ctxt, ectxt);

in your error handler.  Check out mcm_err_func(MCM_ERR_FUNC_ARGS) as a
starting point, it's pretty basic but gets everything.  I've patched
your mcache lib with the above to fix the error handling problems.
pgmemcache has some code in there too...

http://cvs.pgfoundry.org/cgi-bin/cvsweb.cgi/pgmemcache/pgmemcache/pgmemc
ache.c?rev=1.11&content-type=text/x-cvsweb-markup

Look for: memcache_err_func()

... I don't know that I have a URL for the ruby handler, but I think
those provide some decent examples.  -sc
