I noticed a little glitch here:
src/xml.c: virBufferAdd(buf, "(usbdevice tablet)", 13); src/xml.c: virBufferAdd(buf, "(usbdevice tablet)", 18);
So I mounted a campaign to remove all such uses of virBufferAdd and make sure no more sneak back in. First, I added this definition:
#define virBufferAddLit(buf_, literal_string_) \ virBufferAdd (buf_, "" literal_string_ "", sizeof literal_string_ - 1)
The empty double quotes ensure that you get a syntax error if you pass anything other than a string literal in the 2nd parameter.
The idea being to change, e.g., the above examples to this:
virBufferAddLit(buf, "(usbdevice tablet)");
FYI, I converted almost all of the uses of virBufferAdd like this:
This is great - every single place where virBufferAdd is used without a 3rd param of '-'1 is a bug waiting to strike. So how about we now remove the 3rd param from virBufferAdd, since it should only be used for non-literals now & you don't know the length of those ahead of time making the 3rd param useless.
