All values in Memcached itself are strings (byte arrays, technically).

[gsecillano]

How does increment work in this case?

[gsecillano]

This doesn't seem to have feature parity with memcache-client.

[evan]

Increment works because the server itself serializes and deserializes the value to an ASCII string.

Feature parity with memcache-client isn't really the goal; what problem did you encounter?

2 issues: -Cannot store true as raw (Cannot convert true into String) -My server does not increment, saying the value stored is non-numeric.

I will post the specs later.

[evan]

Again, true is a rich type and must be serialized to a string. If you use raw=false to marshal the object it will work.

Did you initialize the key to "0" (a string with the single character 0) before trying to increment it?

By default it sets the Marshaled string which is not ASCII. Initialize your key with:

c.set 'foo', '0', true

[gsecillano]

Yes, I was about to respond saying that I did exactly that. Now increment works. Thanks!

[evan]

Great, ok. It is a known bug that the error isn't reported properly: #110
