In other words, inside Python code, I can define a bunch of useful variables and functions and I want them to be available in the Python shell opened later by subprocess call. It is useful in the sense that sometimes you want a customized Python shell to test your environment. </p>

2,613,762 | 2,613,763 | Content Script cross domain or message passing | <p>I am writing a javascript extention that modifies a website. The extention adds a button to the website, and when clicked it modifies the page content. My script has to send cross domain xmlhttprequests to websiteB, and gets permissions upon installation to do so. </p>
<p>My problem is that the code that runs in the content scope of the website that I am modifying does not have permission to do cross domain requests, because it is within a content scope of the webpage. Nor can I easily pass variables between my main extention code and the code that runs upon the button click on the page.</p>
<p>These are the relevant parts of my code:</p>
<pre><code> // ==UserScript==
// @include http://www.WebsiteB.com/*
// @match http://www.WebsiteB.com/*
// ==/UserScript==
var a = 1;
button.innerHTML = '<a href="javascript:void(0)" onclick="myFunc();">clickMe</a>';
menu.appendChild(button);
contentEval(function() {
myFunc = function() {
//a is undefined
//this part does not have cross domain request permission
};
}
</code></pre>
<p>I use contentEval taken from <a href="http://wiki.greasespot.net/Content_Script_Injection" rel="nofollow">http://wiki.greasespot.net/Content_Script_Injection</a> to get the relevant code to be able to interact with the page my script is running on. Without it, I would not be able to call myFunc from a button on the website.
variables can not be transferred from the main code area to myFunc() by passing them directly using myFunc(a) either. myFunc(1) works, but does not suit my needs.</p>
<p>It's possible that I am going about things the wrong way. If so, please enlighten me.</p>
<p>Is there a way to have cross domain permissions from the code that interacts with the web page?
If not, what should I use to do message passing from the main code area to the content script of the page?</p>

I also would like to have the other files in the directory:</p>

<li><code>hello.rar</code></li>
<li><code>test.part1.rar</code></li>

<p>The attacker uploads a file, it probably won't execute if it were a virus yet it's still using bandwidth/storage for that moment. Would the file go into the PHP <code>/tmp</code> directory just by doing this? Wouldn't this make every form some-what insecure as a user can upload a file in any form?</p>
<p>On a bigger scale what if 100,000 people added that to the DOM and uploaded a random gigabyte file? Wouldn't that temporarily make them hit their bandwidth and/or storage mark?</p>

4,602,891 | 4,602,892 | Problems trying to assign **varname to *varname[]. c++ | <p>In my .h, I have a variable, <code>Texture ** skyboxTextures</code>. I assign some texture pointers in one method, and use them right away:</p>
<pre><code>Texture *skt[] = {
tleft,
tright,
tfront,
tback,
tup,
tdown
};
skyboxTextures = skt;
for(int i = 0; i < 6; i++)
{
skyboxTextures[i]->load();
}
</code></pre>
<p>Then later in another method I try to use the textures again.</p>
<pre><code>Texture *skt[] = skyboxTextures;
// Render the front quad
skyboxTextures[0]->activate();
</code></pre>
<p>This is my issue I cannot access my objects any more. This will not compile because of this error:</p>
<pre><code>error C2440: 'initializing' : cannot convert from 'Texture **' to 'Texture *[]'
</code></pre>
<p>If I comment out the line <code>Texture *skt[] = skyboxTextures;</code>, all I get are invalid texture pointers.</p>

<p><strong>MISTAKE</strong>
I was using firebug to debug the code and it seems that using that code in firebugs watch window is what is causing it to break</p>
