  • Illustration of buffer overflows for students (linux, C)

    - by osgx
    Hello My friend is teacher of first-year CS students. We want to show them buffer overflow exploitation. But modern distribs are protected from simples buffer overflows: HOME=`perl -e "print 'A'x269"` one_widely_used_utility_is_here --help on debian (blame it) Caught signal 11, on modern commercial redhat *** buffer overflow detected ***: /usr/bin/one_widely_used_utility_is_here terminated ======= Backtrace: ========= /lib/libc.so.6(__chk_fail+0x41)[0xc321c1] /lib/libc.so.6(__strcpy_chk+0x43)[0xc315e3] /usr/bin/one_widely_used_utility_is_here[0x805xxxc] /usr/bin/one_widely_used_utility_is_here[0x804xxxc] /lib/libc.so.6(__libc_start_main+0xdc)[0xb61e9c] /usr/bin/one_widely_used_utility_is_here[0x804xxx1] ======= Memory map: ======== 00336000-00341000 r-xp 00000000 08:02 2751047 /lib/libgcc_s-4.1.2-20080825.so.1 00341000-00342000 rwxp 0000a000 08:02 2751047 /lib/libgcc_s-4.1.2-20080825.so.1 008f3000-008f4000 r-xp 008f3000 00:00 0 [vdso] The same detector fails for more synthetic examples from the internet. How can we demonstrate buffer overflow with modern non-GPL distribs (there is no debian in classes) How can we DISABLE canary word checking in stack ? DISABLE checking variants of strcpy/strcat ? write an example (in plain C) with working buffer overrun ?

  • Sendmail background process sometimes processes queue, but sendmail -q always works

    - by markmcb
    I'm using sendmail version 8.14.4 on Fedora 15 to send email. My Rails app uses delayed_job to queue up emails. Messages will queue up in /var/spool/mqueue as expected, but don't always get processed. I can see the messages and sendmail is definitely running in the background. Restarting the process does nothing. However, when I issue the sendmail -q command, sendmail gets to work and starts sending. The really odd thing is that this behavior only occurs sometimes. Other times message queue up and are delivered as expected. I've tried tweaking various sendmail configs to reduce the time between queue processing (for example, adding define('confMIN_QUEUE_AGE', '0')dnl to /etc/mail/sendmail.mc), but nothing seems to do the trick. Any ideas what might be the root cause?

  • Core Location in iPhone Simulator 3.2 (iPad)

    - by choise
    So, i'm trying to port my app to iPad. I'm using CoreLocation. Apple says the iPad does have Location: Wi-Fi Digital compass Assisted GPS (Wi-Fi + 3G model) Cellular (Wi-Fi + 3G model) so it should be possible to get the position of my ipad (at least with 3g model) about 3km radius would be enought. but it doesnt work in simulator (3.2 ipad) (running 3.1.3 in simulator simulates me cupertino). is there a way to get the position in simulator (3.2 ipad) ? i live in germany and here the ipad isnt released yet, so i cannot test it on my device. thanks!

  • How to search for newline or linebreak characters in Excel?

    - by Highly Irregular
    I've imported some data into Excel (from a text file) and it contains some sort of newline characters. It looks like this initially: If I hit F2 (to edit) then Enter (to save changes) on each of the cells with a newline (without actually editing anything), Excel automatically changes the layout to look like this: I don't want these newlines characters here, as it messes up data processing further down the track. How can I do a search for these to detect more of them? The usual search function doesn't accept an enter character as a search character.

  • bind (hardlink) one directory to many places

    - by PoltoS
    I need to "bind" one directory to many chrooted places. I know that I can do "mount -o bind", but this requires special processing on startup each time (run the mount). Is there a way to do it on the filesystem directly? My fs is ext4 and it seems not to support hardlinks to directories. Hardlinking all files inside is not an option too. Is thee a way to enable hardlinks to directories in ext4? Or any other options are avilable?

  • kmemsize problems in VPS even when there is about 500MB free mem

    - by Amer
    Hello, I have a site hosted on a Plesk VPS with 512MB memory and keep on getting kmemsize in "black zone" QoS errors. The soft limit of kmemsize is 12,288,832 and hard limit is 13,517,715. The definition Virtuozzo gives is: Size of unswappable memory, allocated by the operating system kernel. What's eating up the kmemsize? Is there any way to reconfigure and increase the kmemsize? The servers barely have any load or processing. Thanks for the help...

  • iPhone - strange error when testing on simulator

    - by lostInTransit
    Hi I was testing my app on the simulator when it crashed on clicking a button of a UIAlertView. I stopped debugging there, made some changes to the code and built the app again. Now when I run the application, I get this error in the console Couldn't register com.myApp.debug with the bootstrap server. Error: unknown error code. This generally means that another instance of this process was already running or is hung in the debugger.Program received signal: “SIGABRT”. I tried removing the app from the simulator, doing a clean build but I still get this error when I try to run the app. Can someone please let me know what I should do to be able to run the app on my simulator again. Thanks.

  • Why do I get a null pointer exception from TabWidget?

    - by rushinge
    I'm writing an android program in which I have an activity that uses tabs. The Activity public class UnitActivity extends TabActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TabHost tabHost = getTabHost(); TabSpec spec; Resources res = getResources(); LayoutInflater.from(this).inflate(R.layout.unit_view, tabHost.getTabContentView(), true); spec = tabHost.newTabSpec("controls"); spec.setIndicator("Control", res.getDrawable(R.drawable.ic_tab_equalizer)); spec.setContent(R.id.txtview); tabHost.addTab(spec); } } The XML referenced by R.layout.unit_view <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"> <TextView android:id="@+id/txtview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="bottom" android:text="nullpointer this!" /> </FrameLayout> </LinearLayout> </TabHost> As far as I can see I'm doing the same thing I see in the tabs1 api sample from the android sdk. I've tried "getLayoutInflator()" instead of "LayoutInflator.from(this)" with the same result. If I replace the LayoutInflater line with "setContentView(R.layout.unit_view)" my program doesn't crash with a null pointer exception but my content is completely blank and empty. I get the tab and that's it. I've checked to make sure R.layout.unit_view and tabHost are not null when it runs the LayoutInflater line and they seem to be fine. They're defenitely not null. I've also checked to make sure LayoutInflater.from(this) returns a valid layout inflater object and it does. The logcat indicating the error says E/AndroidRuntime( 541): java.lang.NullPointerException E/AndroidRuntime( 541): at android.widget.TabWidget.dispatchDraw(TabWidget.java:206) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.View.draw(View.java:6538) E/AndroidRuntime( 541): at android.widget.FrameLayout.draw(FrameLayout.java:352) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1531) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.ViewGroup.drawChild(ViewGroup.java:1529) E/AndroidRuntime( 541): at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1258) E/AndroidRuntime( 541): at android.view.View.draw(View.java:6538) E/AndroidRuntime( 541): at android.widget.FrameLayout.draw(FrameLayout.java:352) E/AndroidRuntime( 541): at com.android.internal.policy.impl.PhoneWindow$DecorView.draw(PhoneWindow.java:1830) E/AndroidRuntime( 541): at android.view.ViewRoot.draw(ViewRoot.java:1349) E/AndroidRuntime( 541): at android.view.ViewRoot.performTraversals(ViewRoot.java:1114) E/AndroidRuntime( 541): at android.view.ViewRoot.handleMessage(ViewRoot.java:1633) E/AndroidRuntime( 541): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 541): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 541): at android.app.ActivityThread.main(ActivityThread.java:4363) E/AndroidRuntime( 541): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 541): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 541): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) E/AndroidRuntime( 541): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) E/AndroidRuntime( 541): at dalvik.system.NativeStart.main(Native Method) I/Process ( 61): Sending signal.

My actual program is more complex and has more than one tab but I simplified it down to this in an attempt to find out why it's crashing but it still crashes and I don't know why. If I don't use LayoutInflator my program doesn't crash but I don't get any content either, just tabs.

  • Replace JBoss error page with Axis2 fault XML response

    - by Dario
    I'm developing a webservice with Axis2 1.4.1 on JBoss 4.2.3/Tomcat 5.5.27 and Java 1.5.0 (15-b04). It works flawlessly but when an exception happens I get a JBoss error 500 HTML page instead of an Axis2 XML/SOAP fault. This behavoir is vexing, because it difficults to handle errors in the webservice client or in SoapUI while developing. Can I change this to get the SOAP fault? Maybe it's just an Axis2 or JBoss parameter, but I didn't find any clue about. EDIT: Here goes the new stacktrace: [ERROR] WSDoAllReceiver: security processing failed org.apache.axis2.AxisFault: WSDoAllReceiver: security processing failed at org.apache.rampart.handler.WSDoAllReceiver.processBasic(WSDoAllReceiver.java:214) at org.apache.rampart.handler.WSDoAllReceiver.processMessage(WSDoAllReceiver.java:86) at org.apache.rampart.handler.WSDoAllHandler.invoke(WSDoAllHandler.java:72) at org.apache.axis2.engine.Phase.invoke(Phase.java:317) at org.apache.axis2.engine.AxisEngine.invoke(AxisEngine.java:264) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:163) at org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:275) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:133) at javax.servlet.http.HttpServlet.service(HttpServlet.java:647) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:875) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:595) Caused by: org.apache.ws.security.WSSecurityException: The security token could not be authenticated or authorized at org.apache.ws.security.processor.UsernameTokenProcessor.handleUsernameToken(UsernameTokenProcessor.java:155) at org.apache.ws.security.processor.UsernameTokenProcessor.handleToken(UsernameTokenProcessor.java:53) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:311) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:228) at org.apache.rampart.handler.WSDoAllReceiver.processBasic(WSDoAllReceiver.java:211) ... 23 more [ERROR] Servlet.service() para servlet AxisServlet lanzó excepción java.lang.NullPointerException at org.apache.rampart.RampartMessageData.<init>(RampartMessageData.java:308) at org.apache.rampart.MessageBuilder.build(MessageBuilder.java:61) at org.apache.rampart.handler.RampartSender.invoke(RampartSender.java:64) at org.apache.axis2.engine.Phase.invoke(Phase.java:317) at org.apache.axis2.engine.AxisEngine.invoke(AxisEngine.java:264) at org.apache.axis2.engine.AxisEngine.sendFault(AxisEngine.java:520) at org.apache.axis2.transport.http.AxisServlet.handleFault(AxisServlet.java:416) at org.apache.axis2.transport.http.AxisServlet.processAxisFault(AxisServlet.java:379) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:167) at javax.servlet.http.HttpServlet.service(HttpServlet.java:647) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:875) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:595) EDIT 2: After giving the bounty I found that I was wrong about 1.2.9-SNAPSHOT version of Axiom. I built it again, made sure the jars where correctly copied to lib directory and it worked! Finally, it was an Axiom bug, as said in the links provided by Vineet. Thanks!

  • Emacs - Error when calling (server-start)

    - by Jonas Gorauskas
    I am currently using GNU Emacs 23.0.93.1 in Windows Vista SP1. In my .emacs file I make a call to (server-start) and that is causing an error with the message The directory ~/.emacs.d/server is unsafe. Has anyone seen this and know a fix or workaround? ... other than leaving server turned off ;) Here is the stack trace: Debugger entered--Lisp error: (error "The directory ~/.emacs.d/server is unsafe") signal(error ("The directory ~/.emacs.d/server is unsafe")) error("The directory %s is unsafe" "~/.emacs.d/server") server-ensure-safe-dir("~\\.emacs.d\\server\\") server-start(nil) call-interactively(server-start t nil) execute-extended-command(nil) call-interactively(execute-extended-command nil nil)

  • BAD DC transfering FSMO Roles to ADC

    - by Suleman
    I have a DC (FQDN:server.icmcpk.local) and an ADC (FQDN:file-server.icmcpk.local). Recently my DC is facing a bad sector problem so I changed the Operation Masters to file-server for all five roles. but when ever i turn off the OLD DC the file-server also stops wroking with AD and GPMC further i m also unable to join any other computer to this domain. For Test purpose i also added a new ADC (FQDN:wds-server.icmcpk.local) but no succes with the old DC off i had to turn the old DC on and then joined it. I m attaching the Dcdiags for all three servers. Kindly help me so that i b able to reinstall new HDD and it can go online again. --------------------------------------- Server --------------------------------------- C:\Program Files\Support Tools>dcdiag Domain Controller Diagnosis Performing initial setup: Done gathering initial info.

  • IIS7 500 error if form is submitted more than 120 seconds after it was originally loaded

    - by user41170
    Summary: When I submit a form (via POST) to php more than 120 seconds after the form was first called I get a 500 server error. If I submit before 120 seconds, the form works fine. I'm obviously encountering some kind of timeout but I don't know where to look. I've enabled failed request tracing and received the following error: ModuleName="FastCgiModule", Notification="EXECUTE_REQUEST_HANDLER", HttpStatus="500", HttpReason="Internal Server Error", HttpSubStatus="0", ErrorCode="The I/O operation has been aborted because of either a thread exit or an application request. (0x800703e3)", ConfigExceptionInfo="" I don't understand why it matters when the form is submitted relative to the time the form is first rendered (note: the actual form processing takes a fraction of a second). Shouldn't these two requests be stateless? Suggestions? Configuration: Windows Vista SP1 IIS7 php 5.2.x under fastCGI This is a development server running on my laptop. All calls to IIS are coming from localhost.

  • UITableView background customization strange behavior

    - by Omer
    Hi, There is a couple of hours that I'm trying to set a tableView background image. My controller is a subclass of UITableViewController, and I simply wrote this lines of code in ViewDidLoad method. UIImage *image = [UIImage imageNamed:@"home-portrait-iphone.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; self.tableView.backgroundView = imageView; Everything looks great on the simulator, I mean, I see my table and as background view, y can see the image. But when the app is running on the device (ipod touch), I get this error: Program received signal: “SIGABRT”. and the stack says: * -[UITableView setBackgroundView:]: unrecognized selector sent to instance 0x812e00 Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '** -[UITableView setBackgroundView:]: unrecognized selector sent to instance 0x812e00' and the exception is thrown in the assignment, a mean this line: self.tableView.backgroundView = imageView; any ideas? Thank you in advance.

  • How to make sure my GPO are applied in the correct order

    - by Florent
    I'm deploying VMware player through a GPO, and I'd like to apply specific ACLs to the install folder, and to the D:\VMWARE folder I'm creating during the player install. I also have to add the vmware user account the "can log on locally" right. To do so, I've created a GPO whose scope is the same as my Vmware player install GPO. This GPO works well, BUT when applied at the same time as my deployment GPO, it seems to be applied before the deploy GPO, and then : - Cannot find the vmware user account - Cannot find the c:\program files\vmware folder - Cannot find the D:\vmware folder because none of them have already been created by the vmware player install. And the only way for me to apply my security GPO is to execute gpudate /force command manually, which i don't want to use (it's supposed to be an automatic install) I've checked the gpo processing order, my security GPO should be applied AFTER my install GPO (security GPO is number 1, deploy GPO is number to), but it don't seem to be the case. Does anyone got an idea to solve this ?

  • Will using Apache's ProxyPass directive on persistent Ajax connections alleviate the connection limit error?

    - by naurus
    I've got some javascript that keeps a persistent Ajax connection open for each client, and I know that this can cause some serious issues for apache, but not for lighttpd. One thing I learned from researching how to get around this was how to use the ProxyPass directive to send all requests for a certain directory to another address:port combination (without letting the user know). What I want to know is, if I put my PHP in a proxy'd (to lighttpd) directory and call that with javascript, will this still count against my apache connection limit? The reason I wonder is that apache is still serving the content, just not processing it. Seems to me that this would be a connection. Thanks

  • Boost Thread Hanging on _endthreadex

    - by FranticPedantic
    I think I am making a simple mistake, but since I noticed there are many boost experts here, I thought I would ask for help. I am trying to use boost threads(1_40) on windows xp. The main program loads a dll, starts the thread like so (note this is not in a class, the static does not mean static to a class but private to the file). static boost::thread network_thread; network_start() { // do network stuff until quit is signaled } DllClass::InitInstance() { network_thread = boost::thread(boost::bind<void>(network_start)); } DllClass::ExitInstance() { //signal quit (which works) //the following code is slightly verbose because I'm trying to figure out what's wrong try { if (network_thread.joinable() ) { network_thread.join(); } else { TRACE("Too late!"); } } catch (boost::thread_interrupted&) { TRACE("NET INTERRUPTED"); } } The problem is that the main thread is hanging on the join, and the network thread is hanging at the end of _endthreadex. What am I misunderstanding?

  • How to detect defunct processes on Linux?

    - by Hakan
    I have a parent and a child process written in C language. Somewhere in the parent process HUP signal is sent to the child. I want my parent process to detect if the child is dead. But when I send SIGHUP, the child process becomes a zombie. How can I detect if the child is a zombie in the parent process? I try the code below, but it doesn't return me the desired result since the child process is still there but it is defunct. kill(childPID, 0); One more question; can I kill the zombie child without killing the parent? Thanks.

  • Is it possible to load balance requests from a single source?

    - by Shawn
    In our application, Server A establishes a TCP connection with Server B, then it sends a large amount of requests to Server B over the TCP connection. The request message is XML-based. Server B needs to respond within a very short period, and it takes time to process the requests. So we hope a load balancer can be introduced and we can expedite the processing by using multiple Server B's. This is not a web application. I did some research but failed to find a similar application of load balancer. Can anyone tell me if there's a load balancer can help in our application?

  • Why does IHttpAsyncHandler leak memory under load?

    - by Anton
    I have noticed that the .NET IHttpAsyncHandler (and the IHttpHandler, to a lesser degree) leak memory when subjected to concurrent web requests. In my tests, the development web server (Cassini) jumps from 6MB memory to over 100MB, and once the test is finished, none of it is reclaimed. The problem can be reproduced easily. Create a new solution (LeakyHandler) with two projects: An ASP.NET web application (LeakyHandler.WebApp) A Console application (LeakyHandler.ConsoleApp) In LeakyHandler.WebApp: Create a class called TestHandler that implements IHttpAsyncHandler. In the request processing, do a brief Sleep and end the response. Add the HTTP handler to Web.config as test.ashx. In LeakyHandler.ConsoleApp: Generate a large number of HttpWebRequests to test.ashx and execute them asynchronously. As the number of HttpWebRequests (sampleSize) is increased, the memory leak is made more and more apparent. LeakyHandler.WebApp TestHandler.cs namespace LeakyHandler.WebApp { public class TestHandler : IHttpAsyncHandler { #region IHttpAsyncHandler Members private ProcessRequestDelegate Delegate { get; set; } public delegate void ProcessRequestDelegate(HttpContext context); public IAsyncResult BeginProcessRequest(HttpContext context, AsyncCallback cb, object extraData) { Delegate = ProcessRequest; return Delegate.BeginInvoke(context, cb, extraData); } public void EndProcessRequest(IAsyncResult result) { Delegate.EndInvoke(result); } #endregion #region IHttpHandler Members public bool IsReusable { get { return true; } } public void ProcessRequest(HttpContext context) { Thread.Sleep(10); context.Response.End(); } #endregion } } LeakyHandler.WebApp Web.config <?xml version="1.0"?> <configuration> <system.web> <compilation debug="false" /> <httpHandlers> <add verb="POST" path="test.ashx" type="LeakyHandler.WebApp.TestHandler" /> </httpHandlers> </system.web> </configuration> LeakyHandler.ConsoleApp Program.cs namespace LeakyHandler.ConsoleApp { class Program { private static int sampleSize = 10000; private static int startedCount = 0; private static int completedCount = 0; static void Main(string[] args) { Console.WriteLine("Press any key to start."); Console.ReadKey(); string url = "http://localhost:3000/test.ashx"; for (int i = 0; i < sampleSize; i++) { HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); request.Method = "POST"; request.BeginGetResponse(GetResponseCallback, request); Console.WriteLine("S: " + Interlocked.Increment(ref startedCount)); } Console.ReadKey(); } static void GetResponseCallback(IAsyncResult result) { HttpWebRequest request = (HttpWebRequest)result.AsyncState; HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(result); try { using (Stream stream = response.GetResponseStream()) { using (StreamReader streamReader = new StreamReader(stream)) { streamReader.ReadToEnd(); System.Console.WriteLine("C: " + Interlocked.Increment(ref completedCount)); } } response.Close(); } catch (Exception ex) { System.Console.WriteLine("Error processing response: " + ex.Message); } } } }

  • How to stop a QDialog from executing while still in the __init__ statement(or immediatly after)?

    - by Jonathan
    I am wondering how I can go about stopping a dialog from opening if certain conditions are met in its __init__ statement. The following code tries to call the 'self.close()' function and it does, but (I'm assuming) since the dialog has not yet started its event loop, that it doesn't trigger the close event? So is there another way to close and/or stop the dialog from opening without triggering an event? Example code: from PyQt4 import QtCore, QtGui class dlg_closeInit(QtGui.QDialog): ''' Close the dialog if a certain condition is met in the __init__ statement ''' def __init__(self): QtGui.QDialog.__init__(self) self.txt_mytext = QtGui.QLineEdit('some text') self.btn_accept = QtGui.QPushButton('Accept') self.myLayout = QtGui.QVBoxLayout(self) self.myLayout.addWidget(self.txt_mytext) self.myLayout.addWidget(self.btn_accept) self.setLayout(self.myLayout) # Connect the button self.connect(self.btn_accept,QtCore.SIGNAL('clicked()'), self.on_accept) self.close() def on_accept(self): # Get the data... self.mydata = self.txt_mytext.text() self.accept() def get_data(self): return self.mydata def closeEvent(self, event): print 'Closing...' if __name__ == '__main__': import sys app = QtGui.QApplication(sys.argv) dialog = dlg_closeInit() if dialog.exec_(): print dialog.get_data() else: print "Failed"

  • NAS that supports NZB downloading for around £150 ($220) or less (without hard drive)

    - by Jigs
    I have seen a number of NAS's that are around that price, but I am worried that they may not be able to handle the processing of .rar files (I know that can be quite CPU intensive). Does anyone have any experiences with sabnzbd or hellanzb - or similar on their NAS? In terms of features the main requirement is NZB downloading - I am quite flexible on the other features. Wifi support would be nice, but not essential. Torrent downloading would also be nice. One disk drive would probably be enough. Easy installation of application would be nice... but again I am sure I can follow a tutorial.

While the problem isn't reproducible on a regular basis, one page containing 3 dynamic graphs triggers it sometimes, so I suspect some kind of race condition that leads to an endless loop or a stuck busywait. The problem is, I have not yet found a way to debug this thing. There's nothing in the Zope logs and nothing in the system logs. I tried the suggestions from this question to get a stacktrace, but the only signal that has any effect is SIGKILL. Is there another possibility to find out where exactly the process is when it gets stuck?
