-------------------------------------------
Summary: Ambari Web: convert non-async AJAX calls to async
Key: AMBARI-8310
URL: https://issues.apache.org/jira/browse/AMBARI-8310
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 1.7.0
Reporter: Antonenko Alexander
Assignee: Antonenko Alexander
Priority: Critical
Fix For: 2.0.0
We removed most of non-async calls, but there's a few that still need to be
converted.
Non-async calls are problematic. If the request is not satisfied for whatever
reason - say wifi drops, it completely blocks the browser tab (you cannot even
close the browser tab in Chrome):
ambari-web/app/controllers/wizard.js:
loadServiceComponents: function () {
return App.ajax.send({
name: 'wizard.service_components',
sender: this,
data: {
stackUrl: App.get('stackVersionURL'),
stackVersion: App.get('currentStackVersionNumber'),
async: false
},
success: 'loadServiceComponentsSuccessCallback',
error: 'loadServiceComponentsErrorCallback'
});
},
ambari-web/app/utils/ajax/ajax.js:
'router.authentication': {
'real': '/clusters?fields=Clusters/provisioning_state',
'mock': '/data/clusters/info.json',
'format': function() {
return {
async: false
};
}
},
ambari-web/app/utils/polling.js:
setRequestId: function () {
if (App.get('testMode')) {
this.set('requestId', '1');
this.doPolling();
return;
}
var self = this;
var url = this.get('url');
var method = 'PUT';
var data = this.get('data');
$.ajax({
type: method,
url: url,
async: false,
data: data,
