release-1.9
Last change on this file since 7777ac2 was 7777ac2, checked in by Edward Z. Yang <ezyang@mit.edu>, 10 years ago
Convert to async (both Facebook::Graph and us.) Work items: - Documentation is all out of date - Think more carefully about error handling (right now it's delayed into the response object) - Really bad HTTP POST hack in Publish.pm. Signed-off-by: Edward Z. Yang <ezyang@mit.edu>
