the code here

azureupload:function(filename,accountname,key,container,callback) { var buffer = new buffer(this.data); retryoperations = new azure.exponentialretrypolicyfilter(); blobservice = azure.createblobservice(accountname, key).withfilter(retryoperations); var blockid = this.blockarray[this.blockarray.length-1]; var stream = new readablestreambuffer(buffer); var self = this; future = npm.require('fibers/future'); var myfuture = new future; blobservice.createblockfromstream(blockid,container,filename,stream,stream.size(),function(err,response) { if(err) { myfuture.return(); } else if (response) { if (self.bytesuploaded+self.data.length >= self.size) { blobservice.commitblocks(container, filename, {latestblocks: self.blockarray}, function(error, result){ if(error){ myfuture.return(); } else { myfuture.return({url:"https://"+accountname+".blob.core.windows.net/"+container+"/"+filename}); } }); } else { myfuture.return(); } } }); homecoming myfuture.wait(); }
