  • Setting Environment Variable for nginx and Rails consumption

    - by kolrie
    Apache's module mod_env offers a handy way of setting environment variables in configuration files, like: <VirtualHost *:80> ServerName xyz.com DocumentRoot /var/www/rails_app/public PassengerAppRoot /var/www/rails_app SetEnv MY_VARIABLE contents </VirtualHost> http://httpd.apache.org/docs/2.0/mod/mod_env.html#setenv However, in nginx I couldn't find anything that serves the same purpose. What's the alternative here? I thought of setting environment variables in .profile files (I am using Ubuntu 10.04), but that wouldn't have the same "per vHost" isolation I have with Apache, right? What are the alternatives here?

  • Do ALL your variables need to be declared private? [closed]

    - by skizeey
    Possible Duplicate: Why do we need private variables? I know that it's best practice to stay safe, and that we should always prevent others from directly accessing a class' properties. I hear this all the time from university professors, and I also see this all the time in a lot of source code released on the App Hub. In fact, professors say that they will actually take marks off for every variable that gets declared public. Now, this leaves me always declaring variables as private. No matter what. Even if each of these variables were to have both a getter and a setter. But here's the problem: it's tedious work. I tend to quickly lose interest in a project every time I need to have a variable in a class that could have simply been declared public instead of private with a getter and a setter. So my question is, do I really need to declare all my variables private? Or could I declare some variables public whenever they require both a getter and a setter?

  • Where should you store variables for a search program in java?

    - by Bored915
    I'm wondering which is a more effective storage method in java. Would be better to save variables that will not change in a class or a resource? They're going to be variables that contain a set amount so that later a search program will go through the list of variables so as to recognize possible options. Also if there is a more efficient method of storing them please say so or if i doesn't matter where i store them.

  • Can I set Session timeout for a specified Session variable differently than other Session Variables

    - by Eppz
    I'd like to set the timeout on a specific Session Variable in a .Net web application, but leave other Session variables alone. Is this possible? Example: I have 5 Session Variables Session(var1) Session(var2) Session(var3) Session(var4) Session(var5) I want to set it so that Session(var1) through Session(var4) have a timeout of 8 hours (480 minutes), but Session(var5) has a timeout of 20 minutes. Can it be done?

  • Inspecting variables in Xdebug problems

    - by tom
    I've been using xdebug to do php debugging (netbeans or eclipse). I am usually able to inspect variables OK. However, sometimes when I expand a disclosure triangle for a variable -- typically when the client is making an AJAX call -- it will result in an empty response being returned and causing the AJAX call to fail. Has anyone run into this? Is there a way to make PHP debugging with xdebug more robust? (Not being able to inspect variables defeats the purpose of a debugger. Thanks

  • Python: load variables in a dict into namespace

    - by celil
    I want to use a bunch of local variables defined in a function, outside of the function, so I am passing x=locals() as a return value. How can I load all the variables defined in that dictionary into the namespace outside the function, so that instead of accessing the value using x['variable'], I could simply use variable.

  • c declaring variables in blocks

    - by anon
    I know that in C++, I can declare variables pretty much everywhere. I recall once reading that in C, variables must be declared at the top of a function i.e. the following is invalid: void foo() { int good; if (...) { int bad; } } In the above code, is the declaraing of the bad varaible legal by C standards, or only legal due to a gcc extension? Thanks!

  • PHP: How to implement a __get-like method for local function variables

    - by Tom Frost
    I'm no stranger to __get(), and have used it to make some very convenient libraries in the past. However, I'm faced with a new challenge (PHP 5.3, abbreviated and simplified my code for this question): <?php namespace test; class View { function __construct($filename, $varArray) { $this->filename = $filename; $this->varArray = $varArray; } function display() { include($this->filename); } function __get($varName) { if (isset($this->varArray[$varName])) return $this->varArray[$varName]; return "?? $varname ??"; } } ?> Above is a very, very simplified system for loading a View. This code would call the view and display it: <?php require_once("View.php"); use test\View; $view = new View("views/myview.php", array("user" => "Tom")); $view->display(); ?> My goal for this code is to allow the view "myview.php" to contain code like this: <p> Hello <?php echo $user; ?>! Your E-mail is <?php echo $email; ?> </p> And, used with the above code, this would output "Hello Tom! Your E-mail is ?? email ??" However, this won't work. The view is being included within a class method, so when it refers to $user and $email, it's looking for local function variables -- not variables belonging to the View class. For this reason, __get never gets triggered. I could change all my view's variables to things like $this-user and $this-email, but that would be a messy and unintuitive solution. I'd love to find a way where I can reference variables directly WITHOUT having PHP throw an error when an undefined variable is used. Thoughts? Is there a clean way to do this, or am I forced to resort to hacky solutions?

  • Codeigniter how to access class variables

    - by Obay
    I thought this was going to be a no-brainer but I can't seem to access member variables: class MyObject extends Controller { private $START_OF_WEEK = 1; /* constructor here */ function index() { echo $this->$START_OF_WEEK; } } echo $this->$START_OF_WEEK; says Cannot access empty property How do I access member variables? Or... how do I declare them correctly?

  • Making all variables accessible to namespace

    - by Gökhan Sever
    Hello, Say I have a simple function: def myfunc(): a = 4.2 b = 5.5 ... many similar variables ... I use this function one time only and I am wondering what is the easiest way to make all the variables inside the function accessible to my main name-space. Do I have to declare global for each item? or any other suggested methods? Thanks.

  • Using GET Method to Maintain Variables After Logging In

    - by John
    Hello, I am using a login system. When I navigate to comments/index.php without logging in, some variables get passed along using the GET method just fine. Then, if I log in while I am on this page, these variables disappear. The variables that disappear are $submission, $submissionid, and $url. I thought I could use the GET method to keep them live after logging in by appending ?submission='.$submission.'&submissionid='.$submissionid.'&url='.$url.' to the URL of the login form action as seen below. But the variables still disappeared after I made this addition. The relevant code I am trying to use is below. Any idea what I can do to make it do what I want? Thanks in advance, John In comments/index.php: require_once "header.php"; include "login.php"; include "comments.php"; In login.php: if (!isLoggedIn()) { if (isset($_POST['cmdlogin'])) { if (checkLogin($_POST['username'], $_POST['password'])) { show_userbox(); } else { echo "Incorrect Login information !"; show_loginform(); } } else { show_loginform(); } } else { show_userbox(); } In comments.php: $url = mysql_real_escape_string($_GET['url']); echo '<div class="subcommenttitle"><a href="http://www.'.$url.'">'.$submission.'</a></div>'; $submission = mysql_real_escape_string($_GET['submission']); $submissionid = mysql_real_escape_string($_GET['submissionid']); The login function: function show_loginform($disabled = false) { echo '<form name="login-form" id="login-form" method="post" action="./index.php?submission='.$submission.'&submissionid='.$submissionid.'&url='.$url.'"> <div class="usernameformtext"><label title="Username">Username: </label></div> <div class="usernameformfield"><input tabindex="1" accesskey="u" name="username" type="text" maxlength="30" id="username" /></div> <div class="passwordformtext"><label title="Password">Password: </label></div> <div class="passwordformfield"><input tabindex="2" accesskey="p" name="password" type="password" maxlength="15" id="password" /></div> <div class="registertext"><a href="http://www...com/sandbox/register.php" title="Register">Register</a></div> <div class="lostpasswordtext"><a href="http://www...com/sandbox/lostpassword.php" title="Lost Password">Lost password?</a></div> <p class="loginbutton"><input tabindex="3" accesskey="l" type="submit" name="cmdlogin" value="Login" '; if ($disabled == true) { echo 'disabled="disabled"'; } echo ' /></p></form>'; }

  • ANTLR, Dynamic variables

    - by JTS
    Hello, I have an ANTLR grammar that can parse and evaluate simple expressions like 1+2*4, etc. What I would like to do is to evaluate expressions like 2+$a-$b/4 where the $ variables are dynamic variables, that come from an external source and are continuously updated. Is there any design pattern on how to do this using ANTLR, best practices, etc? Shall I "substring" the $a with the updated value ($a - 4.34) A nicer way to do this? Thx

  • How to keep PayPal variables secure

    - by dclowd9901
    I'm trying to link my 3rd party shopping cart to PayPal, and in the process I'm finding that my variables are extremely exposed, such that, if someone uses, say, Firebug, to manipulate the values of my variables, they can change the cost of the items in the transaction. I'm very new to online carts and shopping, so my question is how do I keep this layer of exposure away from users and secure for the website?

  • View list of all JavaScript variables in Google Chrome Console

    - by GRboss
    Hello everyone. In Firebug the DOM tab shows a list of all your public variables and objects. In Chrome's console you have to type the name of the public variable or object you want to explore. Is there a way - or at least a command - for Chrome's console to display a list all the public variables and objects? It will save a lot of typing. Thank you all Stefanos

    - by haansi
    Hello, I am doing web based projects in dotnet. Currently I am implementing security using session variables. I keep current user id and user type in session and authenticate user from these session variables (say Session["UserId"],Session["UserName"] and Session["UserType"]) I do authentications. Please guide me how it is insecure ? I heard such security can be broken and applications can be hacked very easily, like it is possible to get session id and directly connect to that session id etc. Please guide me on this thanks
