  • How to use pthread_atfork() and pthread_once() to reinitialize mutexes in child processes

    - by Blair Zajac
    We have a C++ shared library that uses ZeroC's Ice library for RPC and unless we shut down Ice's runtime, we've observed child processes hanging on random mutexes. The Ice runtime starts threads, has many internal mutexes and keeps open file descriptors to servers. Additionally, we have a few of mutexes of our own to protect our internal state. Our shared library is used by hundreds of internal applications so we don't have control over when the process calls fork(), so we need a way to safely shutdown Ice and lock our mutexes while the process forks. Reading the POSIX standard on pthread_atfork() on handling mutexes and internal state: Alternatively, some libraries might have been able to supply just a child routine that reinitializes the mutexes in the library and all associated states to some known value (for example, what it was when the image was originally executed). This approach is not possible, though, because implementations are allowed to fail *_init() and *_destroy() calls for mutexes and locks if the mutex or lock is still locked. In this case, the child routine is not able to reinitialize the mutexes and locks. On Linux, the this test C program returns EPERM from pthread_mutex_unlock() in the child pthread_atfork() handler. Linux requires adding _NP to the PTHREAD_MUTEX_ERRORCHECK macro for it to compile. This program is linked from this good thread. Given that it's technically not safe or legal to unlock or destroy a mutex in the child, I'm thinking it's better to have pointers to mutexes and then have the child make new pthread_mutex_t on the heap and leave the parent's mutexes alone, thereby having a small memory leak. The only issue is how to reinitialize the state of the library and I'm thinking of reseting a pthread_once_t. Maybe because POSIX has an initializer for pthread_once_t that it can be reset to its initial state. #include <pthread.h> #include <stdlib.h> #include <string.h> static pthread_once_t once_control = PTHREAD_ONCE_INIT; static pthread_mutex_t *mutex_ptr = 0; static void setup_new_mutex() { mutex_ptr = malloc(sizeof(*mutex_ptr)); pthread_mutex_init(mutex_ptr, 0); } static void prepare() { pthread_mutex_lock(mutex_ptr); } static void parent() { pthread_mutex_unlock(mutex_ptr); } static void child() { // Reset the once control. pthread_once_t once = PTHREAD_ONCE_INIT; memcpy(&once_control, &once, sizeof(once_control)); setup_new_mutex(); } static void init() { setup_new_mutex(); pthread_atfork(&prepare, &parent, &child); } int my_library_call(int arg) { pthread_once(&once_control, &init); pthread_mutex_lock(mutex_ptr); // Do something here that requires the lock. int result = 2*arg; pthread_mutex_unlock(mutex_ptr); return result; } In the above sample in the child() I only reset the pthread_once_t by making a copy of a fresh pthread_once_t initialized with PTHREAD_ONCE_INIT. A new pthread_mutex_t is only created when the library function is invoked in the child process. This is hacky but maybe the best way of dealing with this skirting the standards. If the pthread_once_t contains a mutex then the system must have a way of initializing it from its PTHREAD_ONCE_INIT state. If it contains a pointer to a mutex allocated on the heap than it'll be forced to allocate a new one and set the address in the pthread_once_t. I'm hoping it doesn't use the address of the pthread_once_t for anything special which would defeat this. Searching comp.programming.threads group for pthread_atfork() shows a lot of good discussion and how little the POSIX standards really provides to solve this problem. There's also the issue that one should only call async-signal-safe functions from pthread_atfork() handlers, and it appears the most important one is the child handler, where only a memcpy() is done. Does this work? Is there a better way of dealing with the requirements of our shared library?

  • Url rewriting stops working after changing default port on iis7

    - by Somesh
    I have migrated the IIS6 webserver 2003 websites to IIS7 webserver 2008 using msdeploy tool. Application pool setting are changed with "Enable 32-bit Applications=true", "Managed_Pipeline_Mode=Classic","Identity=NetworkService" Framework=v1.1/2.0. All the websites are working fine on default port along with url rewriting migrated from iis6. When I start the webserver on port other than default port by changing bindings, url rewriting stops workings and get 404 error in logs. I think I don't have to change the handler mapping cause I am running it in classic mode. How can I troubleshoot this?

  • Snippets between desktop and laptop

    - by Jamie F
    The Situation: At work, I have a nice beefy desktop running Windows Server 2008 R2 (SharePoint dev machine). My handy ThinkPad is right next to it. Every once in a while I'd like to cut and paste or share something (usually text) between the machines: for example, I might be headed out and I'd like to take send the URL I'm reading from the desktop to the laptop. Of course I can create a share or use the Admin shares and create files to get stuff back and forth, but that seems heavyweight for what I'm thinking of. I'm thinking more along the lines of sending myself an IM. How do you get little things from machine to machine? Keep a shared folder pinned to the taskbar? Send an email to yourself? Bookmark sync? While on it, I'm looking for a decent multiple clipboard handler: maybe these two functions are combined in some nice little utility? I suspect I'm missing something simple here... Thanks... Jamie F.

  • Google App Engine - Secure Cookies

    - by tponthieux
    I'd been searching for a way to do cookie based authentication/sessions in Google App Engine because I don't like the idea of memcache based sessions, and I also don't like the idea of forcing users to create google accounts just to use a website. I stumbled across someone's posting that mentioned some signed cookie functions from the Tornado framework and it looks like what I need. What I have in mind is storing a user's id in a tamper proof cookie, and maybe using a decorator for the request handlers to test the authentication status of the user, and as a side benefit the user id will be available to the request handler for datastore work and such. The concept would be similar to forms authentication in ASP.NET. This code comes from the web.py module of the Tornado framework. According to the docstrings, it "Signs and timestamps a cookie so it cannot be forged" and "Returns the given signed cookie if it validates, or None." I've tried to use it in an App Engine Project, but I don't understand the nuances of trying to get these methods to work in the context of the request handler. Can someone show me the right way to do this without losing the functionality that the FriendFeed developers put into it? The set_secure_cookie, and get_secure_cookie portions are the most important, but it would be nice to be able to use the other methods as well. #!/usr/bin/env python import Cookie import base64 import time import hashlib import hmac import datetime import re import calendar import email.utils import logging def _utf8(s): if isinstance(s, unicode): return s.encode("utf-8") assert isinstance(s, str) return s def _unicode(s): if isinstance(s, str): try: return s.decode("utf-8") except UnicodeDecodeError: raise HTTPError(400, "Non-utf8 argument") assert isinstance(s, unicode) return s def _time_independent_equals(a, b): if len(a) != len(b): return False result = 0 for x, y in zip(a, b): result |= ord(x) ^ ord(y) return result == 0 def cookies(self): """A dictionary of Cookie.Morsel objects.""" if not hasattr(self,"_cookies"): self._cookies = Cookie.BaseCookie() if "Cookie" in self.request.headers: try: self._cookies.load(self.request.headers["Cookie"]) except: self.clear_all_cookies() return self._cookies def _cookie_signature(self,*parts): self.require_setting("cookie_secret","secure cookies") hash = hmac.new(self.application.settings["cookie_secret"], digestmod=hashlib.sha1) for part in parts:hash.update(part) return hash.hexdigest() def get_cookie(self,name,default=None): """Gets the value of the cookie with the given name,else default.""" if name in self.cookies: return self.cookies[name].value return default def set_cookie(self,name,value,domain=None,expires=None,path="/", expires_days=None): """Sets the given cookie name/value with the given options.""" name = _utf8(name) value = _utf8(value) if re.search(r"[\x00-\x20]",name + value): # Don't let us accidentally inject bad stuff raise ValueError("Invalid cookie %r:%r" % (name,value)) if not hasattr(self,"_new_cookies"): self._new_cookies = [] new_cookie = Cookie.BaseCookie() self._new_cookies.append(new_cookie) new_cookie[name] = value if domain: new_cookie[name]["domain"] = domain if expires_days is not None and not expires: expires = datetime.datetime.utcnow() + datetime.timedelta( days=expires_days) if expires: timestamp = calendar.timegm(expires.utctimetuple()) new_cookie[name]["expires"] = email.utils.formatdate( timestamp,localtime=False,usegmt=True) if path: new_cookie[name]["path"] = path def clear_cookie(self,name,path="/",domain=None): """Deletes the cookie with the given name.""" expires = datetime.datetime.utcnow() - datetime.timedelta(days=365) self.set_cookie(name,value="",path=path,expires=expires, domain=domain) def clear_all_cookies(self): """Deletes all the cookies the user sent with this request.""" for name in self.cookies.iterkeys(): self.clear_cookie(name) def set_secure_cookie(self,name,value,expires_days=30,**kwargs): """Signs and timestamps a cookie so it cannot be forged""" timestamp = str(int(time.time())) value = base64.b64encode(value) signature = self._cookie_signature(name,value,timestamp) value = "|".join([value,timestamp,signature]) self.set_cookie(name,value,expires_days=expires_days,**kwargs) def get_secure_cookie(self,name,include_name=True,value=None): """Returns the given signed cookie if it validates,or None""" if value is None:value = self.get_cookie(name) if not value:return None parts = value.split("|") if len(parts) != 3:return None if include_name: signature = self._cookie_signature(name,parts[0],parts[1]) else: signature = self._cookie_signature(parts[0],parts[1]) if not _time_independent_equals(parts[2],signature): logging.warning("Invalid cookie signature %r",value) return None timestamp = int(parts[1]) if timestamp < time.time() - 31 * 86400: logging.warning("Expired cookie %r",value) return None try: return base64.b64decode(parts[0]) except: return None uid=1234|1234567890|d32b9e9c67274fa062e2599fd659cc14 Parts: 1. uid is the name of the key 2. 1234 is your value in clear 3. 1234567890 is the timestamp 4. d32b9e9c67274fa062e2599fd659cc14 is the signature made from the value and the timestamp

  • How to improve the HTML formatting in Evolution mail client

    - by Tom
    I have a question about viewing HTML emails in the Evolution mail client. Basically, I am receiving some emails that look lovely in Thunderbird but not in Evolution because the HTML rendering of Evolution isn't as advanced. Does anyone know how to improve the HTML rendering of Evolution? e.g. a plugin, tip, code patch, etc... The closest I've got is to right-click the email, "Save As...", save as a html file, then open in Firefox. Not exactly streamline! What emails can't it display well? We use the subversion revision control system which is set up to send an email whenever someone commits via svnnotify all nicely coloured via the --handler HTML::ColorDiff -d parameter. When Evolution fails to use the colours, I find it very had to read the raw diff.

  • Send files ending in .mp4 in Apache with HTTP 206 Partial Content

    - by Pacha
    I am using Apache as web server and the return code is always HTTP/1.1 200. I want to set some kind of handler or use a mod to return HTTP/1.1 206 when the extension of the file requested is .mp4 so it can do video seeking, my web server is already returning some headers to do seeking, but it doesn't work.

  • NGINX : Proxy pass intercepting 5xx errors - Possible to differentiate between ones fired by backed vs ones fired by nginx itself?

    - by anonymous-one
    We use proxy_intercept_errors ( http://wiki.nginx.org/HttpProxyModule#proxy_intercept_errors ) with our backends. We intercept a number of status codes, including a few 5xx ones. Our 5xx (each 500 has its own) handler has an access_log so we can see all the 5xx errors returned to the user in a nice clean logged format. The issue with this is that as it stands now, we cannot tell weather a 5xx was returned to the user by nginx or intercepted from our backend. Is there any way to differentiate between the two? Thanks.

  • Apache, Django with mod_wsgi, and large request buffering

    - by Mukul
    In my setup of Apache 2.2 MPM worker and Django 1.3 with mod_wsgi 2.8, I need to support large POST request payloads. The problem is that when there are many such simultaneous requests, Apache uses up all the memory in the system and then crashes. It seems that Apache is buffering the requests completely in memory before executing the WSGI handler and passing it the request. Is there any way to control request buffering in Apache? The log shows the following error whenever the crash happens: [Wed Jun 29 18:35:27 2011] [error] cgid daemon process died, restarting Here's my virtual host's configuration: <VirtualHost *:8080> ServerName example.com ErrorLog /var/log/apache2/error.log WSGIScriptAlias / <path to django.wsgi> WSGIPassAuthorization on WSGIDaemonProcess example.com WSGIProcessGroup example.com XSendFileAllowAbove on XSendFile on </VirtualHost>

  • Problem with socket communication between C# and Flex

    - by Chris Lee
    Hi all, I am implementing a simulated b/s stock data system. I am using flex and c# for client and server sides. I found flash has a security policy and I handled the policy-file-request in my server code. But seems it doesn't work, because the code jumped out at "socket.Receive(b)" after connection. I've tried sending message on client in the connection handler, in that case the server can receive correct message. But the auto-generated "policy-file-request" can never be received, and the client can get no data sending from server. Here I put my code snippet. my ActionScript code: public class StockClient extends Sprite { private var hostName:String = "192.168.84.103"; private var port:uint = 55555; private var socket:XMLSocket; public function StockClient() { socket = new XMLSocket(); configureListeners(socket); socket.connect(hostName, port); } public function send(data:Object) : void{ socket.send(data); } private function configureListeners(dispatcher:IEventDispatcher):void { dispatcher.addEventListener(Event.CLOSE, closeHandler); dispatcher.addEventListener(Event.CONNECT, connectHandler); dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler); dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler); dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler); dispatcher.addEventListener(ProgressEvent.SOCKET_DATA, dataHandler); } private function closeHandler(event:Event):void { trace("closeHandler: " + event); } private function connectHandler(event:Event):void { trace("connectHandler: " + event); //following testing message can be received, but client can't invoke data handler //send("<policy-file-request/>"); } private function dataHandler(event:ProgressEvent):void { //never fired trace("dataHandler: " + event); } private function ioErrorHandler(event:IOErrorEvent):void { trace("ioErrorHandler: " + event); } private function progressHandler(event:ProgressEvent):void { trace("progressHandler loaded:" + event.bytesLoaded + " total: " + event.bytesTotal); } private function securityErrorHandler(event:SecurityErrorEvent):void { trace("securityErrorHandler: " + event); } } my C# code: const int PORT_NUMBER = 55555; const String BEGIN_REQUEST = "begin"; const String END_REQUEST = "end"; const String POLICY_REQUEST = "<policy-file-request/>\u0000"; const String POLICY_FILE = "<?xml version=\"1.0\"?>\n" + "<!DOCTYPE cross-domain-policy SYSTEM \"http://www.adobe.com/xml/dtds/cross-domain-policy.dtd\">\n" + "<cross-domain-policy> \n" + " <allow-access-from domain=\"*\" to-ports=\"55555\"/> \n" + "</cross-domain-policy>\u0000"; ................ private void startListening() { provider = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); provider.Bind(new IPEndPoint(IPAddress.Parse("192.168.84.103"), PORT_NUMBER)); provider.Listen(10); isListened = true; while (isListened) { Socket socket = provider.Accept(); Console.WriteLine("connect!"); byte[] b = new byte[1024]; int receiveLength = 0; try { // code jump out at this statement receiveLength = socket.Receive(b); } catch (Exception e) { Debug.WriteLine(e.ToString()); } String request = System.Text.Encoding.UTF8.GetString(b, 0, receiveLength); Console.WriteLine("request:"+request); if (request == POLICY_REQUEST) { socket.Send(Encoding.UTF8.GetBytes(POLICY_FILE)); Console.WriteLine("response:" + POLICY_FILE); } else if (request == END_REQUEST) { Dispose(socket); } else { StartSocket(socket); break; } } } Sorry for the long code, please someone help with it, thanks a million

  • ObjectContext.SaveChanges() fails with SQL CE

    - by David Veeneman
    I am creating a model-first Entity Framework 4 app that uses SQL CE as its data store. All is well until I call ObjectContext.SaveChanges() to save changes to the entities in the model. At that point, SaveChanges() throws a System.Data.UpdateException, with an inner exception message that reads as follows: Server-generated keys and server-generated values are not supported by SQL Server Compact. I am completely puzzled by this message. Any idea what is going on and how to fix it? Thanks. Here is the Exception dump: System.Data.UpdateException was unhandled Message=An error occurred while updating the entries. See the inner exception for details.

  • NullPointerException in ItemizedOverlay.getIndexToDraw

    - by lyricsboy
    I have a relatively simple MapActivity that I'm trying to make display a list of "camps" within a given map region. I've created a custom subclass of OverlayItem called CampOverlayItem, a custom ItemizedOverlay called CampsOverlay that returns CampOverlayItems, and of course a MapActivity subclass that populates the map. I'm pulling the overlay data from a database using an AsyncTask as created in my activity. The AsyncTask is triggered from a ViewTreeObserver.OnGlobalLayoutListener attached to the MapView. In the onPostExecute method of the AsyncTask, I create a new instance of my CampsOverlay class and pass it a list of the camps returned from the database (which are fetched in doInBackground). I then call: mapView.getOverlays().add(newOverlay); where newOverlay is the CampsOverlay I just created. All of this code runs without error, but when the Map tries to draw itself, I get a NullPointerException with the following stack trace: java.lang.NullPointerException at com.google.android.maps.ItemizedOverlay.getIndexToDraw(ItemizedOverlay.java: 211) at com.google.android.maps.ItemizedOverlay.draw(ItemizedOverlay.java:240) at com.google.android.maps.Overlay.draw(Overlay.java:179) at com.google.android.maps.OverlayBundle.draw(OverlayBundle.java: 42) at com.google.android.maps.MapView.onDraw(MapView.java:476) at android.view.View.draw(View.java:6274) at android.view.ViewGroup.drawChild(ViewGroup.java:1526) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.ViewGroup.drawChild(ViewGroup.java:1524) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.View.draw(View.java:6277) at android.widget.FrameLayout.draw(FrameLayout.java:352) at android.view.ViewGroup.drawChild(ViewGroup.java:1526) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.ViewGroup.drawChild(ViewGroup.java:1524) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.ViewGroup.drawChild(ViewGroup.java:1524) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.ViewGroup.drawChild(ViewGroup.java:1524) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.ViewGroup.drawChild(ViewGroup.java:1524) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.View.draw(View.java:6277) at android.widget.FrameLayout.draw(FrameLayout.java:352) at android.view.ViewGroup.drawChild(ViewGroup.java:1526) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.View.draw(View.java:6277) at android.widget.FrameLayout.draw(FrameLayout.java:352) at com.android.internal.policy.impl.PhoneWindow $DecorView.draw(PhoneWindow.java:1883) at android.view.ViewRoot.draw(ViewRoot.java:1332) at android.view.ViewRoot.performTraversals(ViewRoot.java:1097) at android.view.ViewRoot.handleMessage(ViewRoot.java:1613) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4203) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit $MethodAndArgsCaller.run(ZygoteInit.java:791) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) at dalvik.system.NativeStart.main(Native Method) Because it seems particularly relevant, here is the code for my ItemizedOverlay subclass: public class CampsOverlay extends ItemizedOverlay<CampOverlayItem> { private ArrayList<Camp> camps = null; public CampsOverlay(Drawable defaultMarker, ArrayList<Camp> theCamps) { super(defaultMarker); this.camps = theCamps; } @Override protected CampOverlayItem createItem(int i) { Camp camp = camps.get(i); CampOverlayItem item = new CampOverlayItem(camp); return item; } @Override protected boolean onTap(int index) { // TODO Auto-generated method stub return super.onTap(index); } @Override public int size() { return camps.size(); } } Does anyone have any idea what could be happening here? I've attempted to verify that everything I have control over is non-null. I can provide more code if necessary.

  • How to start process as a daemon?

    - by Markus Johansson
    I have created a service which consists of a web fronted (nginx), python runner glue handler (uwsgi) and my own python code (fetcher). I have made a script (deploy.sh) to start the difference services: nginx uwsgi --ini inifie.ini python fetcher.py & disown My question is regarding how I start my python daemon. I want it to run in the background. It should not print anything to my current terminal. If I add "print" calls to my fetcher script I currently see them in the terminal window. So my question is: how do I start my fetcher.py script as a daemon?

  • BroadcastReceiver not reading stored value from SharedPreferences

    - by bobby123
    In my app I have a broadcast receiver that turns on GPS upon receiving a set string of text. In the onLocationChanged method, I want to pass the GPS data and a value from my shared preferences to a thread in a string. I have the thread writing to log and can see all the GPS values in the string but the last value from my shared preferences is just showing up as 'prefPhoneNum' which I initialised the string to at the beginning of the receiver class. I have the same code to read the prefPhoneNum from shared preferences in the main class and it works there, can anyone see what I might be doing wrong? public class SmsReceiver extends BroadcastReceiver implements LocationListener { LocationManager lm; LocationListener loc; public SharedPreferences sharedpreferences; public static final String US = "usersettings"; public String prefPhoneNum = "prefPhoneNum"; @Override public void onReceive(Context context, Intent intent) { sharedpreferences = context.getSharedPreferences(US, Context.MODE_PRIVATE); prefPhoneNum = sharedpreferences.getString("prefPhoneNum" , ""); lm = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE); loc = new SmsReceiver(); //---get the SMS message passed in--- Bundle bundle = intent.getExtras(); SmsMessage[] msgs = null; String str = ""; if (bundle != null) { //---retrieve the SMS message received--- Object[] pdus = (Object[]) bundle.get("pdus"); msgs = new SmsMessage[pdus.length]; for (int i=0; i<msgs.length; i++) { msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]); str += msgs[i].getMessageBody().toString() + "\n"; } Toast.makeText(context, str, Toast.LENGTH_SHORT).show(); //Display SMS if ((msgs[0].getMessageBody().toString().equals("Enable")) || (msgs[0].getMessageBody().toString().equals("enable"))) { enableGPS(); } else { /* Do Nothing*/ } } } public void enableGPS() { //new CountDownTimer(10000, 1000) { //10 seconds new CountDownTimer(300000, 1000) { //300 secs = 5 mins public void onTick(long millisUntilFinished) { lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, loc); } public void onFinish() { lm.removeUpdates(loc); } }.start(); } @Override public void onLocationChanged(Location location) { String s = ""; s += location.getLatitude() + "\n"; s += location.getLongitude() + "\n"; s += location.getAltitude() + "\n"; s += location.getAccuracy() + "\n" + prefPhoneNum; Thread cThread = new Thread(new SocketsClient(s)); cThread.start(); } @Override public void onProviderDisabled(String provider) { } @Override public void onProviderEnabled(String provider) { } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } } Here is the logcat for when the application shuts - D/LocationManager( 3912): requestLocationUpdates: provider = gps, listener = accel.working.TrackGPS@4628bce0 D/GpsLocationProvider( 96): setMinTime 0 D/GpsLocationProvider( 96): startNavigating D/GpsLocationProvider( 96): TTFF: 3227 D/AndroidRuntime( 3912): Shutting down VM W/dalvikvm( 3912): threadid=1: thread exiting with uncaught exception (group=0x400259f8) E/AndroidRuntime( 3912): FATAL EXCEPTION: main E/AndroidRuntime( 3912): java.lang.NullPointerException E/AndroidRuntime( 3912): at android.content.ContextWrapper.getSharedPreferences(ContextWrapper.java:146) E/AndroidRuntime( 3912): at accel.working.TrackGPS.onLocationChanged(TrackGPS.java:63) E/AndroidRuntime( 3912): at android.location.LocationManager$ListenerTransport._handleMessage(LocationManager.java:191) E/AndroidRuntime( 3912): at android.location.LocationManager$ListenerTransport.access$000(LocationManager.java:124) E/AndroidRuntime( 3912): at android.location.LocationManager$ListenerTransport$1.handleMessage(LocationManager.java:140) E/AndroidRuntime( 3912): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 3912): at android.os.Looper.loop(Looper.java:144) E/AndroidRuntime( 3912): at android.app.ActivityThread.main(ActivityThread.java:4937) E/AndroidRuntime( 3912): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 3912): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 3912): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) E/AndroidRuntime( 3912): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) E/AndroidRuntime( 3912): at dalvik.system.NativeStart.main(Native Method)

    I have a standard asp.net 2.0 application running on IIS 6. I have noticed some strange exception messages in the logs. They seem to be caused by random spam bots trying to submit forms. They are strange because the request string is huge and all the exception details in the event manager are messed up, they have been replaced with %21,%22, etc.. as seen in the screen shot. Is this some kind of exploit or just a bug in the asp.net exception handler/logger ? UPDATE: I traced the requests that are causing this strange log event to a bug in IE8 that causes it to request scriptresource.axd?d={html from page} as described in these links: MS Connect SO - Invalid Webresource.axd SO - IE8 Dropping Memory Pages I am still not sure why these requests would break the IIS log event like seen above, they are just long strings of jiberish being sent to the server, maybe someone reading this can shed some light on it.

  • Apache2 BufferedLogs On - anybody using it ?

    - by Qiqi
    Greetings, I am wondering, whether anybody is using BufferedLogs On with Apache2 and found any issues ? Feature is marked as experimental, but for many years now, so I guess it's rather pretty stable. I am running some servers with constrained disk IO capacity at the moment, so I turned it on hoping that even a small benefit could help in the long run ;-) I do have several to several hundreds requests per seconds so by my thoughts there is really no need to write to log after each request, cause honestly I don't think that my filesystem is the best handler for many unnecessary writes. (OCFS2 shared among several DomUs in the Xen)

  • wave.getState() returns null

    - by RMorrisey
    When trying to call wave.getState() in my Google Wave gadget, I get back null (no state object). How can I initialize the Wave state object? I am working in the Wave Sandbox. My ModulePrefs contains the following: <Require feature="wave" /> <Require feature="rpc"/> I got the "rpc" feature from some google groups post when searching for a fix, but it doesn't seem to be any help. The gadget contains a jQuery plugin, which defines the classes I use (not shown), attaches an event handler to the link that shows up in edit mode, and sets up the callback methods with the google wave gadget initializer: $.fn.extend({ $.gork.InitPass.newButtonClick = function newButtonClick() { var jer = new $.gork.InitPass.Player('Jeremias', 12, 2); var delta = {}; delta[jer.name] = jer.serialize(); wave.getState().submitDelta(delta); }; $.gork.InitPass.modeCallback = function modeCallback() { var state = wave.getState(); var mode = wave.getMode(); $.gork.InitPass.getContainer().ipCombatState(state, (mode == wave.Mode.EDIT)); }; $.gork.InitPass.stateCallback = function stateCallback() { $.gork.InitPass.getContainer().ipCombatState( wave.getState(), (wave.getMode() == wave.Mode.EDIT)); alert('state'); }; $.gork.InitPass.init = function init() { if (wave && wave.isInWaveContainer()) { var mode = wave.getMode(); $('.gork-ip-container').ipCombatState(null, (mode == wave.Mode.EDIT)); wave.setModeCallback($.gork.InitPass.modeCallback); wave.setStateCallback($.gork.InitPass.stateCallback); } }; })(jQuery); gadgets.util.registerOnLoadHandler($.gork.InitPass.init); $(function ready() { $.gork.InitPass.getContainer().find('.gork-ip-edit .addSection a.newButton').click( $.gork.InitPass.newButtonClick); }); So there are two main pieces of functionality here: When the mode changes, ipCombatState(...) is called. This changes the visual appearance of the gadget when the user puts the gadget in Edit mode (CTRL+E), by hiding the view DIV and displaying the edit DIV. The newButtonClick callback (which is attached to the link "a.newButton" in the edit container) is supposed to add Jeremias (Nate's Shadowrun character) to the gadget state, so that he'll be appear as a table row in edit mode. I have verified that the initializer method is called, and the view/edit mode switch works just fine (except the state is null). When I click on the new button link (the link at the bottom in edit mode), and trigger the newButtonClick handler, I get an error because wave.getState() also returns null. How can I initialize the wave state so that I can work with it? The purpose of my gadget will be to keep track of combat initiative order in a Shadowrun tabletop game (4th Ed). You can test it out in Wave and see what I have so far: http://gorkwobble.herobo.com/wave/init-pass.xml The actual javascript code is externalized to: http://gorkwobble.herobo.com/wave/init-pass.js P.S. If any Shadowrun players read this, and want to hear about it when I get the gadget working, leave a comment and I'll wave you.

  • How can I register a custom protocol with xdg ?

    - by julien
    I've been struggling this morning trying to associate an application with a custom protocol, namely emacsclient and org-protocol. I'm calling this protocol from a webbrowser bookmarklet, and I get the following behaviour : In chromium, the "Launch Application" dialog comes up, and calls xdg-open org-protocol://... which ends up firing a new chromium frame. In firefox, I've tried setting network.protocol-handler.app.org-protocol to an empty string or my emacsclient path, anyhow I get the following error message : "Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program" without even showing any external application selection dialog. I'm not using any desktop environment, so I need to make this work strictly with xdg, however, despite reading the shared mime info spec etc, I still can't fathom a working configuration.

  • Why do SNMP agents need MIB files?

    - by user1495181
    After reading up on SNMP and some of the questions help here I think understand the agent role as a SNMP service to device (Like SQL, it is an API to storage). When you execute a SQL query the SQL engine does all the work and returns the result - You don't need to be aware of how the storage and where the storage is done. But MIBs are not actual storage , so what is the role of my agent? if the agent only register the MIB like i follow in this tutorial, is it not used as handler at all? Say that I want monitor my application's pending request queue, so I want an agent that all SNMP request for application_pending_request will be fired for it and it will return the queue depth. Why do I need to have an actual MIB when all I need to poll my application queue in order to get result?
