unit testing - What's the difference between assertEqual and assertIs (assertIs was introduced in Python 2.7)? -

-

संदर्भ - 

  assertEqual (a, b) # जांचता है कि a == b assertIs (ए, बी) # जांचता है कि ए है बी एंड एलटी; ---- जो भी इसका मतलब है ???    
 
 
  assertEqual  का उपयोग करना दो वस्तुओं की आवश्यकता नहीं है एक ही प्रकार, वे केवल एक ही मूल्य की आवश्यकता है। तुलना में,  assertIs  का उपयोग करके दो वस्तुओं को एक ही ऑब्जेक्ट की आवश्यकता होती है।  
  assertEqual  समानता के लिए  ==  परीक्षण ऑपरेटर:  
 
 ऑपरेटर & lt ;, & gt ;, ==, & gt; =, & lt; =, और! = दो वस्तुओं के मूल्यों की तुलना करें वस्तुओं को एक ही प्रकार की आवश्यकता नहीं है। यदि दोनों संख्याएं हैं, तो उन्हें एक सामान्य प्रकार में बदल दिया जाता है। अन्यथा, विभिन्न प्रकार के ऑब्जेक्ट हमेशा असमान की तुलना करते हैं, और इन्हें लगातार, लेकिन स्वैच्छिक रूप से आदेश दिए जाते हैं।   
  assertIs  ऑब्जेक्ट आइडेंट के लिए परीक्षा, जैसा कि  है  और  नहीं है  ऑपरेटर्स:  
 
 ऑपरेटर ऑब्जेक्ट आइडेंटिटी के लिए है और परीक्षा नहीं है: एक्स है y सत्य है अगर और केवल अगर एक्स और वाई समान ऑब्जेक्ट हैं X नहीं है, व्युत्क्रम सत्य मान पैदा करता है।   
 उपरोक्त उद्धरण दोनों पायथन दस्तावेज़ अनुभाग से आते हैं।

php - Creating canonical URLs with custom route-classes -

-
I am trying to implement the canonical url and to combine with custom route classes. URL-SACAME is something like this: / category-x / article / 123 / category-y / article / 123 I am creating a custom route - the expansion of the class Zend_Controller_Router_Route_Regex and checks that the article is 123 and the correct category-name is included in the URL. If the article is in 123 square-X and the user is reaching square-y, then I want to redirect to the correct URL. But there is no clear possibility to do this directly to the roads. What is the best practice approach here? I often do this in my action controller like something ... // Get / Category-Y / Article / 123 $ $ article- & gt; URL is generated, and it contains / category-x / article / 123 if (this-> --request-> getRequestUri ()! = $ Article-> URL) {return $ this- & gt; ; _helper-> Redirector-> GoToUrl ($ paragraph-> url); } In this example, $ article-> The url will need ...

In anticipation of a live scenario, I am creating my entire site, which has a 500 MHz processor with 256 MB A very large 100 MHz RAM I have loaded my database with 200k + rows of garbage data, trying to test my queries. I have seen - obviously because of this, a large display hit all my FAQ using the index, although some 15+ to join (using all indexes) using MySQL To enable 16MB cache, which brings down the query times to nothing but what results? With a dynamic website, I can not see how the cache can help completely when I allow unique queries such as a search feature. I am also using the eaccelerator for PHP. When I use the COUNT (*) total with multiple code JOIN and WHERE , then 10 + There are other queries. Other queries that only get the same line or two do at the same level when I had only a few lines I also noticed that almost 99% of the CPU in CPU CPU stress during a query Comes. Basically I do not know whether the software is on the fault or too much of the h...

mysql - Formatting problem with PHP DateTime Difference when used as part of an equation -

I am trying to write a simple invoicing system. I want to use the Datetime Diff to calculate the cost of each invoice. I have so far: / * In this example $ dayLength and $ ratePerSec is not really the case, but now we use the hypotethical values ​​of 8.0 and 0.0054 Will * / $ date1 = new date time ("Time 1 Form Database", [DateTimeJonof Chase]); $ Date2 = new date time ("Time 2 Form Database", [Datetime Joneof Choice]); $ Diff = $ date2- & gt; Diff ($ date1); $ LenInSec = $ diff- & gt; Format ("% y") * 365 * $ dayLength * 3600 + $ diff- & gt; Format ("% d") * $ dayLength * 3600 + $ diff- & gt; Format ("% H") * 3600 + $ diff- & gt; Format ("% i") * 60 + $ diff- & gt; Format ("% s"); $ Cost = $ lenInSec * $ rate per second; When I try to output cost using $ lenInSec generated from the Deltaime Diff, I actually get weird results. Occasionally, in 1 and 3 out of 1 to 3 times, I get the...
