linux - Why ulimit can't limit resident memory successfully and how? -

-

मैं एक नया बैश खोल शुरू करता हूं, और निष्पादित करता हूं: 

  ulimit -m 102400 ulimit - एक "कोर फाइल आकार (ब्लॉक, -सी) 0 डेटा सेग आकार (kbytes, -d) असीमित समयबद्धन प्राथमिकता (-e) 20 फ़ाइल आकार (ब्लॉक, -एफ) असीमित लंबित संकेत (-i) 16382 अधिकतम लॉक मेमोरी (kbytes , -एल) 64 अधिकतम स्मृति आकार (किलोबाइट, -एम) 102400 खुली फाइलें (-n) 1024 पाइप आकार (512 बाइट्स, -पी) 8 POSIX संदेश कतार (बाइट्स, -क) 819200 वास्तविक समय प्राथमिकता (-आर) असीमित वर्चुअल मेमोरी (kbytes, -v) असीमित फ़ाइल ताले (-x) असीमित "  Pre> 
 और फिर, मैं एक विशाल परियोजना संकलन निष्पादित करता हूं इसका लिंक करना बड़ी स्मृति का उपयोग करेगा, और फिर 2 जी परिणाम, प्रक्रिया ld अधिक 2 जी निवासी स्मृति का इस्तेमाल किया। 
 
 क्या कोई गलत है? निवासी मेमोरी को सीमित करने के लिए मैं कैसे अन्य प्रोग्राम का उपयोग कर सकता हूं? 
 
 सीमा निवासी स्मृति का लक्ष्य है, क्योंकि एक प्रक्रिया लगभग सभी मेमोरी का उपयोग कर कंप्यूटर स्थिर हो जाएगा।

के लिए मैन पेज के अनुसार:

RLIMIT_RSS

प्रक्रिया के निवासी सेट की सीमा (पृष्ठों में) (रैम में निवासी आभासी पेजों की संख्या) निर्दिष्ट करता है। यह सीमा केवल लिनक्स 2.4.x, x & lt; 30, और वहाँ केवल madvise (2) MADV_WILLNEED निर्दिष्ट करने के लिए कॉल को प्रभावित करता है

आप शायद इसके बजाय आभासी स्मृति आकार सेट करना चाहते हैं, ulimit -v

paypal - How to know the URL referrer in PHP? -

-
I'm new to integrating PayPal with sites, so easily from the service I can use Can the available method be? What am I trying to do, when the user clicks on "Return to my website", I want my return URL to know that the referrer is PayPal so I can send it automatically to the homepage . how to do this? I tried $ _ SERVER ['HTTP_REFERER'] but it does not seem like anything. During the IPN conversation I set the cookie and session (though I am not sure whether I am correcting it or doing this right), but on returning to my website, it does not seem to recognize any session . If I use it by using $ _ SERVER ['HTTP_REFERER'] , then I'm afraid it's a security risk, is not it? If so, is there any other way I remember? help please. Should you really know the referrer? Set the PayPal Return URL to a "secret" URL which is always redirected to the homepage. If someone reaches there and gets redirected without coming from PayPal, then ...

oauth - Facebook OAuth2 Logout does not remove fb_ cookie -

-
This is used to work so I'm not sure what's wrong the user just logs in to Facebook properly Is capable of Logging problem. I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page. However, when they return to my site, I find that the FB_ cookie is still there. PHP SDK still gives user FB session details. The strange thing is that www.facebook.com shows that I am already logged out of Facebook. What can be wrong here? Thanks, I've been stumped: (. OK, finally, what did I do? > GetLogoutUrl () with a next = address url on my logout script which will remove the Facebook cookie by setSession (null) .

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...
