A bit unsure where to look for this one...
Context:
HTML5 web page, that uses HTML5 EventSource / server-side events to get refresh notifications
OpenWrt BarrierBreaker server, running uHTTPd as the web server
a two-level CGI script that provides the server-side events:
the CGI is a shell script (ash, not bash), that parses QUERY_STRING, and calls...
a C application that do the true data extraction (from an SQLite database) and pushes the data to the web page
Everything works, except for a little detail: when the web page is closed,
the C application keeps running. Since it doesn't expect any user input, its current structure is a simple while(1). So after some time, the openwrt box has dozens of copies of the app running.
So the question: how can the application be changed to detect that the client isn't there anymore, and that it should quits?
Thanks
[Edit]
Since posting this a few hours ago, i investigated if the information was somehow available in the script's input stream. It appears it isn't.
I also found http://html5doctor.com/server-sent-events/ that describes a strategy to do exactly this in a Node.js environment, but I have no idea how to translate this in a script-based one.

I am going to create a language specific tool to support hight-lighting, code completion etc and found ternjs is a good framework to use. I read the document from http://ternjs.net/doc/ but not quite understand how it works. Based on that document ternjs needs a server to be launched to support the client side. I inspected the on line demo from http://ternjs.net/doc/demo/#simple. When I type command in this demo, I didn't see any http communication happens between my browser and the ternjs server. I am confused about how ternjs server work in this case. Is there a way for me to setup one locally?
I have 1 URLLoader to log the user in, then after the user has logged in successfully, I have another URLLoader which once the user is logged in, it queries back relevant information..
This works perfectly fine on my Mac OSX with MAMP running (when I'm running it as an AIR project), and on CentOS.. But when I try to test it with Windows (WAMP), it doesn't seem to remember the session of the URL-Loader... Any ideas?
What do you mean by "share session"? URLLoader only helps you create requests to the server-side
The URLLoader class downloads data from a URL as text, binary data, or URL-encoded variables. It is useful for downloading text files, XML, or other information to be used in a dynamic, data-driven application.
If you have problem with session in your AIR application, It means you have problem with inner state in your app or on server-side. From information you provided, you should find problems in your session realisation on server-side because of moving logic on WAMP setup. For example, web server doesn't store session etc.
I want to capture all the network calls from Web Driver in Java. I am not doing any UI testing, just testing JS execution and, requests and responses of some network calls.
I tried using Browser Mob as is suggested in most forums, but I need it to work across all browsers. It worked flawlessly with Firefox, but I was facing some issues with the others. Safari driver doesn't event support a Proxy capability.
I don't want to use Fiddler as it involves some manual steps around invoking and storing the calls. Whereas, Browser Mob being an in-code proxy can be integrated in a more smoother fashion.
I also tried using the RC-like package included in Selenium standalone server package. But, I have some HTTPS calls and some nested iframes in cross domains. I am particularly interested in some cross domain POST call and it doesn't work out that well. Also, people keep saying it's not recommended to use that package.
So, I had a solution where we can use a standalone proxy server running on a machine. Using host entries, we'll point Web Driver to hit the proxy instead of the actual server. The proxy will record all the incoming calls and route them to the actual server host. Later, I can make a request to the proxy which will return me all the calls it intercepted. I am not sure whether it's still called a proxy or a router.
I came across TCPmon, but it's no longer being supported. Does anyone know some similar tools that could run on Unix systems or any alternate solutions?
We modified the Fiddler rules script to include a new exec action. If you use their native script editor, it also provide auto complete features and we were comfortably able to get around it. The syntax is similar to that of JavaScript.
The Fiddler package comes with a ExecActions.exe which can be used to pass console arguments to a running Fiddler instance using the command prompt.
The code we wrote processed all the sessions captured by Fiddler and wrote it to a file in a custom JSON format and later used GSON to deserialize it.
Please let me know, if you want further details.
I'm not really sure how to word this exactly, so hopefully someone can make sense of it. I've been working on an iPad app that syncs files from a server to your iPad and lets you build presentations with the various files. The corporation I'm working with on this app has a wireless network that requires you to re-authenticate every hour. So every hour instead of getting the expected JSON api response, any HTTP request pulls down the page needed to reauth with the wireless network. I was wondering is there is a specific HTTP response code related to getting sent that page or a "best-practice" way of testing for that page as opposed to JSON.
Granted I could just test to see if the response is HTML, but that doesn't account for other redirect responses that I haven't found yet. I could just test part of the HTML to see if it matches a predetermined portion of the html, but I'm an outside contractor. I can't guarantee they won't change the markup or verbiage of the page after I've made my deliverable.
So does anyone out in the ether know a "best practices" methodology for testing if the app needs to reauth before syncing?
I noticed that on Mac OS X and maybe even iOS, when you connect to a new Wi-Fi network, it will try to contact www.apple.com. This is being done to check if the internet connectivity is available. If it's not available, the Captive Network Assistant will pop-up, showing you the authentication page, or sometimes when I'm in Starbucks, an advertisement.
Following your question, since Apple themselves is doing it this way, I think you could check for HTTP response code, look for something in the HTML markup (slightly discouraged though) or trying to connect to a known server (Reachability).
For a corporation practicing well-documented projects, I am quite sure they won't be changing things without making sure that your app, once deployed will continue to work.
We have developed a comet based application for chat (using streaming approach). The application has been developed in ASP .Net 3.5 sp1.
The browser has two connections with the server. One for posting and another for receiving chat messages. While load testing with Jmeter or VSTS the posting is getting recorded and load tested but not the receiving portion. Can some one please suggest any load testing tool which can address this issue.
I've come across the same problem, the top runner for me at the moment is browsermob.com. It has a complete API that allows you to create test scenarios that can "watch and wait" on pages recording every http request made as though they are visiting through a real browser. It gets kind of expensive if you need to test with more than 25 concurrent users (browser users), but seems very reasonably priced from what I have seen so far.
It'd be really interesting to see what tools others who are somewhat technically inept are using.
