An extra null pointer check is not needed in functions like the following.

• PrefetchTask::run
• Resource::clear

Hi,
I recompiled a package for debian based on the latest git tree.
Once teapotnet installed and started, I can create a user, but when I try attach a file, there's
nothing appearing in the little box supposed to mention it except a "/" that also appears in the message text box.
If I send that, the message is posted but instead of the picture I see "Loading attachment.../"
On the server, the file seems to be in the _upload directory.

F.

So after making and installing

$ make
$ ./teapotnet

I get an error saying "INFO:Port Mapping is not available"

System details are Ubuntu 12.04.4 LTS 64bit running on AMD E-350 APU.

Would you like to wrap any pointer data members with the template class "std::unique_ptr"?

Update candidates:

• Handler
• Pipe
• Resource

I just downloaded and tried to start (double click) on Mac - nothing happens.

Then I go into the terminal and try to start it here:

$ Teapotnet.app/Contents/MacOS/Teapotnet
Illegal instruction: 4

My Mac OS X Version is 10.7.5
