multithreading - python Queue get()/task_done() issue -

-

कतार के मेरे उपभोक्ता पक्ष: 

  m = queue.get () कतार कार्य_ऑन () & lt; बाकी प्रोग्राम & gt;

प्रश्न:

  1. क्या task_done () प्रभावी रूप से m कतार बंद पॉप करता है और कतार पर उपभोक्ता को जो भी ताला लगा है उसे रिलीज करना है?

  2. मुझे बाकी कार्यक्रम के दौरान m का उपयोग करना होगा क्या यह सुरक्षित है, या मुझे कॉल करने से पहले मुझे इसे कॉपी करने की आवश्यकता है task_done () ?

    3. P>

    नहीं, queue.get () कतार बंद आइटम चबूतरे ऐसा करने के बाद, आप जो भी चाहें कर सकते हैं, जब तक कि निर्माता इसे पसंद करता है और अब इसे स्पर्श नहीं करता। queue.task_done () को केवल कतार को सूचित करने के लिए कहा जाता है कि आप कुछ के साथ किया (यह विशिष्ट आइटम के बारे में भी नहीं पता है, यह कतार में अधूरा वस्तुओं की गणना करता है), ताकि < Code> queue.join () जानता है कि काम खत्म हो गया है।

Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

php - Laravel - Overriding a resource route into a different route filter group -

-
Does Laravel's routing work as expected? What I think, if I want to override a route, then I just have to give the expected route before each other. I have something like this: root :: group (array ('first' = & gt; 'defaultLoads' =); function () {root :: post 'Newsletter', 'newsletter controller @ store'); root: group (array ('(newsletter', 'newsletter controller');}}); That if I post this route, only http://domain.com/newsletter should run only the default loads route filter. However, when I call php Runs artisan routes , I get this: | | POST newsletter | newsletter.store | newslettercontroller@ store | default loads | login | | though it reads the route correctly (PHP artisan loads which The correct path is to the right place) but the file of the resource path even if it is not in the filter group, the path is affected. Then my question: How does it work Laravel? If so, do I post this -> Newsle...
