Subject Re: git commit: updated refs/heads/1843-feature-bigcouch to d260381
Date Sat, 21 Dec 2013 11:44:53 GMT
Agreed! The new work on 1843-feature-bigcouch is aimed at getting a runnable cluster with basic
CRUD, I expect we’ll come back to each commit for tidying up or, such as in this case, added
a pluggable mechanism for general use. You only have to look at some of my other commits to
see that I’m cutting corners right now. make dev currently works to the point where databases
can be created, but doc creation crashes. I’m sure it’s simple but I’ve not had time
to fix it.
