ajax - response.responseText adds previous responseText (node.js, prototype) -

-

यह मेरे node.js फ़ंक्शन है जो res.write का उपयोग करता है: 

  function: ping () {Res.write (JSON.stringify ({"डेटा प्रकार": "पिंग"})); SetTimeout (पिंग, 30000); }   
 यह ग्राहक है, प्रोटोटाइप में लिखित अनुरोध:  
  this.pushconnection = new Ajax.Request (pushserveraddress, {method: 'get', EvalJSON: 'झूठी', इंटरैक्टिव पर: this.pushconnectionInteractive.bind (यह)}); } पुश कनेकशन इंटरैक्टिव: फ़ंक्शन (प्रतिक्रिया) {}   
 समस्या यह है कि  प्रतिक्रिया.प्रस्पतिक पाठ  प्रत्येक  res.write  से बढ़ेगा के माध्यम से।  
 उदाहरण:  
  1 पिंग () प्राप्त किया गया है: response.responseText = {"डेटाटाइप": "पिंग"} दूसरा पिंग () प्राप्त किया गया है: response.responseText = {"डेटा प्रकार": "पिंग"} {"डेटािंग": "पिंग"} 3 पिंग () प्राप्त किया गया है: response.responseText = {"डेटाटाइप": "पिंग"} {"डेटा प्रकार": "पिंग"} {"डेटा प्रकार" : "पिंग"}   
 मुझे यकीन नहीं है कि नोड। जेएस डेटा फिर से भेज रहा है, या यदि प्रोटोटाइप डाटा जमा कर रहा है। मुझे  response.responseText =    res.end () का उपयोग किए बिना अंतिम डेटा भेजा गया है     
 
 
 आप शायद एक बार से अधिक  this.pushconnection  कॉल कर रहे हैं।  
 यदि आप  this.pushconnection  को अपनी Ajax ऑब्जेक्ट के रूप में इन्स्ताइज़ करते हैं और उसी एजेक्स ऑब्जेक्ट का उपयोग करना जारी रखते हैं, तो आपकी प्रतिक्रिया बढ़ेगी।  
 इसके बजाय इसे आज़माएं:  
 < कोड> this.pushconnection = function (pushserveraddress) {नया अजाक्स। अनुरोध (पुशस्क्रेवार्डेड्रेस, {method: 'get', evalJSON: 'false', इंटरैक्टिव पर: this.pushconnectionInteractive.bind (this)}); }   
 तब आप इसे कहकर कॉल कर सकते हैं:  
  var ajax = this.pushconnection ("example.com");

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

memcached - Django cache performance -

-
We are now using Redis for in-memory cache for our Django application (we used the first memcatch The difference in performance is no big, and we're using Redis because the disc dump feature). The problem is that Django cache's performance in my view - terrible, we have a view with 102 cache hits (no miss), and it has 81 ms (only the cash part, which is with the DJBugBug toolbar Is measured). In my opinion - this is a very long time, I know, asking for a question for DB can be 10x more (or 100x) time, but that is also not good with cash performance of that fact. We are running radis (and the first memacatch) on different hosts, connected to the local network with other servers. Is there a way to maximize cache performance in Django? Instead of displaying problem cache, there is a possibility of the number of items to be received for each page 102 Cash calls mean long time lost due to network latency. With full control of the code, you may be able to fix it with m...
