ts low overhead (few instructions for detached
probe site, simple shared library call for enabled probe site) and
native access to application data make it a tool of choice not only
for debugging and tracing the application during development, but also
for monitoring (and even extending!) live production systems.

Play with it in your project, it's a lot of fun!

yone, if you can't sleep knowing
that there's something that it not properly logged in your system yet,
then you better not using it. But logging aside, what your app does
when it receives "NOT STORED" from set? I'm not saying that you never
need a result from set, but I really wonder what real-world cases
might be, couldn't think of any myself.

. But straightforward compression
will likely introduce spaces and newlines as part of binary data.

There seem to be a space in your key between "W=Add/Remove" and
"World::..." Spaces are not allowed there.

it temporary sets SIGPIPE action to SIG_IGN. The latter is
not 100% correct, as it affects all threads in the application, but
will do for most users.

You set expiration time to one second. Since memcached has the timer
of 1 second granularity, it happens so that you add an item at the
edge of a second, and it expires immediately. The solution is to not
set the expiration time ;).

Run
./configure CPPFLAGS=-DAI_ADDRCONFIG=0
AI_ADDRCONFIG is indeed undefined on some BSDs, but it's not a vital
flag, zero is a safe value then.

then how to deal with the above?

tches are always welcome, even
partial UDP support may suit some.
Until then, cache your C::M::F objects! ;)
P.S.: above is just my speculation, if someone send me a script to
reproduce the problem, I'll try to look into it this weekend.
