  • Cross domain ajax POST ie7 with jquery

    - by DickieBoy
    been having trouble with this script, ive managed to get it working in ie8, works on chrome fine. initilize: function(){ $('#my_form').submit(function(){ if ($.browser.msie && window.XDomainRequest) { var data = $('#my_form').serialize(); xdr=new XDomainRequest(); function after_xhr_load() { response = $.parseJSON(xdr.responseText); if(response.number =="incorrect format"){ $('#errors').html('error'); } else { $('#errors').html('worked'); } } xdr.onload = after_xhr_load; xdr.open("POST",$('#my_form').attr('action')+".json"); xdr.send(data); } else { $.ajax({ type: "POST", url: $('#my_form').attr('action')+".json", data: $('#my_form').serialize(), dataType: "json", complete: function(data) { if(data.statusText =="OK"){ $('#errors').html('error'); } if(data.statusText =="Created"){ response = $.parseJSON(data.responseText); $('#errors').html('Here is your code:' +response.code); } } }); } return false; }); } I understand that ie7 does not have the XDomainRequest() object. How can I replicate this in ie7. Thanks, in advance

  • NoSQL for filesystem storage organization and replication?

    - by wheaties
    We've been discussing design of a data warehouse strategy within our group for meeting testing, reproducibility, and data syncing requirements. One of the suggested ideas is to adapt a NoSQL approach using an existing tool rather than try to re-implement a whole lot of the same on a file system. I don't know if a NoSQL approach is even the best approach to what we're trying to accomplish but perhaps if I describe what we need/want you all can help. Most of our files are large, 50+ Gig in size, held in a proprietary, third-party format. We need to be able to access each file by a name/date/source/time/artifact combination. Essentially a key-value pair style look-up. When we query for a file, we don't want to have to load all of it into memory. They're really too large and would swamp our server. We want to be able to somehow get a reference to the file and then use a proprietary, third-party API to ingest portions of it. We want to easily add, remove, and export files from storage. We'd like to set up automatic file replication between two servers (we can write a script for this.) That is, sync the contents of one server with another. We don't need a distributed system where it only appears as if we have one server. We'd like complete replication. We also have other smaller files that have a tree type relationship with the Big files. One file's content will point to the next and so on, and so on. It's not a "spoked wheel," it's a full blown tree. We'd prefer a Python, C or C++ API to work with a system like this but most of us are experienced with a variety of languages. We don't mind as long as it works, gets the job done, and saves us time. What you think? Is there something out there like this?

  • Java: How to make this main thread wait for the new thread to terminate

    - by Jeff Bullard
    I have a java class that creates a process, called child, using ProcessBuilder. The child process generates a lot of output that I am draining on a separate thread to keep the main thread from getting blocked. However, a little later on I need to wait for the output thread to complete/terminate before going on, and I'm not sure how to do that. I think that join() is the usual way to do this but I'm not sure how to do that in this case. Here is the relevant part of the java code. // Capture output from process called child on a separate thread final StringBuffer outtext = new StringBuffer(""); new Thread(new Runnable() { public void run() { InputStream in = null; in = child.getInputStream(); try { if (in != null) { BufferedReader reader = new BufferedReader(new InputStreamReader(in)); String line = reader.readLine(); while ((line != null)) { outtext.append(line).append("\n"); ServerFile.appendUserOpTextFile(userName, opname, outfile, line+"\n"); line = reader.readLine(); } } } catch (IOException iox) { throw new RuntimeException(iox); } } }).start(); // Write input to for the child process on this main thread // String intext = ServerFile.readUserOpTextFile(userName, opname, infile); OutputStream out = child.getOutputStream(); try { out.write(intext.getBytes()); out.close(); } catch (IOException iox) { throw new RuntimeException(iox); } // ***HERE IS WHERE I NEED TO WAIT FOR THE THREAD TO FINISH *** // Other code goes here that needs to wait for outtext to get all // of the output from the process // Then, finally, when all the remaining code is finished, I return // the contents of outtext return outtext.toString();

  • Significance in R

    - by Gemsie
    Ok, this is quite hard to explain, but I'm at a complete loss what to do. I'm a relative newcomer to R and although I can completely admire how powerful it is, I'm not too good at actually using it.... Basically, I have some very contrived data that I need to analyse (it wasn't me who chose this, I can assure you!). I have the right and left hand lengths of lots of people, as well as some numeric data that shows their sociability. Now I would like to know if people who have significantly different lengths of hand are more or less sociable than those who have the same (leading into the research that 'symmetrical' people are more sociable and intelligent, etc. I have got as far as loading the data into R, then I have no idea where to go from there. How on Earth do I start to separate those who are close to symmetrical to those who aren't to then start to do the analysis? Ok, using Sasha's great advice, I did the cor.test and got the following: Pearson's product-moment correlation data: measurements$l.hand - measurements$r.hand and measurements$sociable t = 0.2148, df = 150, p-value = 0.8302 alternative hypothesis: true correlation is not equal to 0 95 percent confidence interval: -0.1420623 0.1762437 sample estimates: cor 0.01753501 I have never used this test before, so am unsure how to intepret it...you wouldn't think I was on my fourth Scientific degree would you?! :(

  • Empty Postbacks on ASP.NET pages

    - by AaronLS
    We are having a problem that seems to only be a problem when accessing our websites from internal intranet machines. When logged into the domain, and accessing our websites, postbacks are not working. Basically the page behaves as if it were refreshed and nothing was changed. When logging the GETs and POSTs with an HTTP analyzer, the post is complete empty and the ContentLength is 0. It is also very sporadic, but seems to be happening fairly often. In the case where it failed, we could see that there was an extra item in the Header for the POST, it was "Authorization" and the value was the word "Negotiate " followed by a space and then a bunch of characters and two equal symbols at the end, which looked like some kind of base64 encoded value. In a case where it succeeded, this Authorization item was no in the header, but I have logged more than one successful cases to know if that is consistent. We have seen this occur only with IE8 so far, and when it occurs it is sometimes sporadic. I can close and open the browser and it will begin working sometimes, and other times it is still broken. What might be causing the postback to be empty? This means the viewstate is not sent to the server which makes the page basically broken. It seems to certainly be a client side issue, but not sure if it's not aggravated by some server settings. Thanks in advance.

  • convert old repository to mercurial

    - by nedlud
    I've been playing around with different versioning systems to find one I'm comfortable with. I started with SVN (lets call this version of the project "f1"), then changed over to GIT. But I didn't know how to convert the old SVN repo to GIT, so I just copied the folder, deleted the .svn stuff, and turned it into a GIT repo (lets call this copied version "f2"). Now I'm playing around with Mercurial and was very pleased to find that it has a Tortoise client for Windows. I was also please to find how easy it was to convert the GIT repo into Mercurial, so I preserved the history (I still cloned it first, just in case. So I'm calling this hg version "f3"). But now what I'm wondering is: what do I do with the old SVN repo that still holds my history from before I played with GIT? I guess I can convert the old SVN repo to Mercurial, but can I then merge those two histories into the one repository so I have a complete set of histories in one place? In other words, can I prepend f1 to f3?

  • [AS3] Calling Php Script with UTF-8 POST variables

    - by kornelijepetak
    AS3 documentation says that Strings in AS3 are in UTF-16 format. There is a textbox on a Flash Clip where user can type some data. When a button is clicked, I want this data to be sent to a php script. I have everything set up, but it seems that the PHP script gets the data in UTF-16 format. The data in the database (which is utf-8) shows some unrecognizable characters (where special characters are used), meaning that the data has not been sent in a correct encoding. var variables:URLVariables=new URLVariables; var varSend:URLRequest=new URLRequest("http://website.com/systematic/accept.php"); varSend.method=URLRequestMethod.POST; varSend.data=variables; var varLoader:URLLoader=new URLLoader; varLoader.dataFormat=URLLoaderDataFormat.VARIABLES; varLoader.addEventListener(Event.COMPLETE, completeHandler); When submit button is clicked, the following handler gets executed. function sendData(event:MouseEvent) : void { // i guess here is the problem (tbName.text is UTF-16) variables.name = tbName.text; varLoader.load(varSend); } Is there any way to send the data so that PHP script gets the data in UTF-8 format? (PHP script is retrieving the value using the $_POST['name']).

  • Resizing FileReference image then reuploading, only reuploads original image.

    - by pfunc
    I can;t figure out how to do this. Someone selects and image after calling FileReference.browse(). I take that image and make a thumbnail in flash. Then I upload that image like so: var newFileReq:URLRequest = new URLRequest(FILE_UPLOAD_TEMP); newFileReq.contentType = "application/octet-stream"; var fileReqVars:URLVariables = new URLVariables(); fileReqVars.image = myThumbImage; fileReqVars.folder = "Thumbs"; newFileReq.data = fileReqVars; newFileReq.method = URLRequestMethod.POST; //upload the first image fileRef.addEventListener(Event.COMPLETE, onFirstFileUp); fileRef.upload(newFileReq, "Filedata"); All this does it upload the original image. How do I change the fileRef to upload the new thumb? I have traced out the size of the "myThumbImage" and it is correct. I have placed it visually on the stage after creating the thumb, and it seems like it works. But when I upload it to an aspx page (that basically just throws it into a folder), it uploads the original larger image.

  • Why is TRest in Tuple<T1... TRest> not constrained?

    - by Anthony Pegram
    In a Tuple, if you have more than 7 items, you can provide an 8th item that is another tuple and define up to 7 items, and then another tuple as the 8th and on and on down the line. However, there is no constraint on the 8th item at compile time. For example, this is legal code for the compiler: var tuple = new Tuple<int, int, int, int, int, int, int, double> (1, 1, 1, 1, 1, 1, 1, 1d); Even though the intellisense documentation says that TRest must be a Tuple. You do not get any error when writing or building the code, it does not manifest until runtime in the form of an ArgumentException. You can roughly implement a Tuple in a few minutes, complete with a Tuple-constrained 8th item. I just wonder why it was left off the current implementation? Is it possibly a forward-compatibility issue where they could add more elements with a hypothetical C# 5? Short version of rough implementation interface IMyTuple { } class MyTuple<T1> : IMyTuple { public T1 Item1 { get; private set; } public MyTuple(T1 item1) { Item1 = item1; } } class MyTuple<T1, T2> : MyTuple<T1> { public T2 Item2 { get; private set; } public MyTuple(T1 item1, T2 item2) : base(item1) { Item2 = item2; } } class MyTuple<T1, T2, TRest> : MyTuple<T1, T2> where TRest : IMyTuple { public TRest Rest { get; private set; } public MyTuple(T1 item1, T2 item2, TRest rest) : base(item1, item2) { Rest = rest; } } ... var mytuple = new MyTuple<int, int, MyTuple<int>>(1, 1, new MyTuple<int>(1)); // legal var mytuple2 = new MyTuple<int, int, int>(1, 2, 3); // illegal

  • How do I update the UI during an event using ASP.NET?

    - by Phil Hale
    I'm a bit stuck with a problem. I feel like the solution should be fairly straight forward but I'm completely out of ideas for some reason. Here's the problem. I've got a user control with a couple of buttons. Think of them as 'On' and 'Off'. When either button is clicked an async method is called. If the method is successful an event is fired. Within the event I want to update the enabled property of the two buttons so that only a single button is clickable at any one time. The problem is that any changes I make to the properties are not shown on screen because the postback is already complete. I tried wrapping the buttons in an UpdatePanel but I get an "Update method can only be called on UpdatePanel with ID 'xxxx' before Render' error. I understand why the problem occurs but I can't think of a solution. Help! Ideally what I'd like to do is simply call a method within the event that will update the UI, but I don't know if that's possible.

  • FileReference.browse() stops playback on some Flash Players

    - by Christophe Herreman
    We have an issue were the server session associated with a Flex client times out when the browse file dialog is open for a time longer then the configured session timeout. It seems that on some players, the playback is stopped when browse or download on a FileReference is executing. This also causes remote calls to be blocked and hence our manual keep-alive messages are not sent to the server, resulting in a session timeout. I searched for some info on this in the docs and found a notice of it, but it does not explicitly list the players it does (not) work. Would anyone know were I could find a complete list? PS: here are the links that mention this behavior: http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_and_communications_7.html While calls to the FileReference.browse(), FileReferenceList.browse(), or FileReference.download() method are executing, most players will continue SWF file playback. http://livedocs.adobe.com/flex/3/langref/flash/net/FileReference.html While calls to the FileReference.browse(), FileReferenceList.browse(), or FileReference.download() methods are executing, SWF file playback pauses in stand-alone and external versions of Flash Player and in AIR for Linux and Mac OS X 10.1 and earlier Anyone knows what is meant with an "external Flash Player"? PPS: we tested this on Linux (10.0.x and 10.1.x) in Firefox where it seems to stop playback and on Windows (10.0.x) in IE where playback seems to continue.

  • Pass a Message From Thread to Update UI

    - by Jay Dee
    Ive created a new thread for a file browser. The thread reads the contents of a directory. What I want to do is update the UI thread to draw a graphical representation of the files and folders. I know I can't update the UI from within a new thread so what I want to do is: whilst the file scanning thread iterates through a directories files and folders pass a file path string back to the UI thread. The handler in the UI thread then draws the graphical representation of the file passed back. public class New_Project extends Activity implements Runnable { private Handler handler = new Handler() { @Override public void handleMessage(Message msg) { Log.d("New Thread","Proccess Complete."); Intent intent = new Intent(); setResult(RESULT_OK, intent); finish(); } }; public void getFiles(){ //if (!XMLEFunctions.canReadExternal(this)) return; pd = ProgressDialog.show(this, "Reading Directory.", "Please Wait...", true, false); Log.d("New Thread","Called"); Thread thread = new Thread(this); thread.start(); } public void run() { Log.d("New Thread","Reading Files"); getFiles(); handler.sendEmptyMessage(0); } public void getFiles() { for (int i=0;i<=allFiles.length-1;i++){ //I WANT TO PASS THE FILE PATH BACK TU A HANDLER IN THE UI //SO IT CAN BE DRAWN. **passFilePathBackToBeDrawn(allFiles[i].toString());** } } }

  • Any useful suggestions to figure out where memory is being free'd in a Win32 process?

    - by LeopardSkinPillBoxHat
    An application I am working with is exhibiting the following behaviour: During a particular high-memory operation, the memory usage of the process under Task Manager (Mem Usage stat) reaches a peak of approximately 2.5GB (Note: A registry key has been set to allow this, as usually there is a maximum of 2GB for a process under 32-bit Windows) After the operation is complete, the process size slowly starts decreasing at a rate of 1MB per second. I am trying to figure out the easiest way to quickly determine who is freeing this memory, and where it is being free'd. I am having trouble attaching a memory profiler to my code, and I don't particularly want to override the new/delete operators to track the allocations/deallocations (IOW, I want to do this without re-compiling my code). Can anyone offer any useful suggestions of how I could do this via the Visual Studio debugger? Update I should also mention that it's a multi-threaded application, so pausing the application and analysing the call stack through the debugger is not the most desirable option. I considered freezing different threads one at a time to see if the memory stops reducing, but I'm fairly certain this will cause the application to crash.

  • object / class methods serialized as well?

    - by Mat90
    I know that data members are saved to disk but I was wondering whether object's/class' methods are saved in binary format as well? Because I found some contradictionary info, for example: Ivor Horton: "Class objects contain function members as well as data members, and all the members, both data and functions, have access specifiers; therefore, to record objects in an external file, the information written to the file must contain complete specifications of all the class structures involved." and: Are methods also serialized along with the data members in .NET? Thus: are method's assembly instructions (opcodes and operands) stored to disk as well? Just like a precompiled LIB or DLL? During the DOS ages I used assembly so now and then. As far as I remember from Delphi and the following site (answer by dan04): Are methods also serialized along with the data members in .NET? sizeof(<OBJECT or CLASS>) will give the size of all data members together (no methods/procedures). Also a nice C example is given there with data and members declared in one class/struct but at runtime these methods are separate procedures acting on a struct of data. However, I think that later class/object implementations like Pascal's VMT may be different in memory.

  • receive and pass values with XML, AS3

  • Renderbuffer Width (Open GL ES)

    - by Josh Elsasser
    I'm currently experiencing an issue with an Open GL ES renderbuffer where the backing and width are are both set to 15. Is there any way to set them to the width of 320 and 480? My project is built up on Apple's EAGLView class and ES1Renderer, but I've moved it from the app delegate to a controller. I also moved the CADisplayLink outside of it (I update my game logic with the timestamp from this) Any help would be greatly appreciated. I add the glview to the window as follows: CGRect applicationFrame = [[UIScreen mainScreen] applicationFrame]; [window addSubview:gameController.glview]; [window makeKeyAndVisible]; I synthesize the controller and the glview within it. The EAGLView and Renderer are otherwise unmodified. Renderer Initialization: // Get the layer CAEAGLLayer *eaglLayer = (CAEAGLLayer *)self.layer; eaglLayer.opaque = TRUE; eaglLayer.drawableProperties = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:FALSE], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGBA8, kEAGLDrawablePropertyColorFormat, nil]; renderer = [[ES1Renderer alloc] init]; Render "resize from layer" Method - (BOOL)resizeFromLayer:(CAEAGLLayer *)layer { // Allocate color buffer backing based on the current layer size glBindRenderbufferOES(GL_RENDERBUFFER_OES, colorRenderbuffer); [context renderbufferStorage:GL_RENDERBUFFER_OES fromDrawable:layer]; glGetRenderbufferParameterivOES(GL_RENDERBUFFER_OES, GL_RENDERBUFFER_WIDTH_OES, &backingWidth); glGetRenderbufferParameterivOES(GL_RENDERBUFFER_OES, GL_RENDERBUFFER_HEIGHT_OES, &backingHeight); NSLog(@"Backing Width:%i and Height: %i", backingWidth, backingHeight); if (glCheckFramebufferStatusOES(GL_FRAMEBUFFER_OES) != GL_FRAMEBUFFER_COMPLETE_OES) { NSLog(@"Failed to make complete framebuffer object %x", glCheckFramebufferStatusOES(GL_FRAMEBUFFER_OES)); return NO; } return YES; }

  • jQuery: Targeting elements added via *non-jQuery* AJAX before any Javascript events fire? Beyond th

    - by peteorpeter
    Working on a Wicket application that adds markup to the DOM after onLoad via Wicket's built-in AJAX for an auto-complete widget. We have an IE6 glitch that means I need to reposition the markup coming in, and I am trying to avoid tampering with the Wicket javascript... blah blah blah... here's what I'm trying to do: New markup arrives in the DOM (I don't have access to a callback) Somehow I know this, so I fire my code. I tried this, hoping the new tags would trigger onLoad events: $("selectorForNewMarkup").live("onLoad", function(){ //using jQuery 1.4.1 //my code }); ...but have become educated that onLoad only fires on the initial page load. Is there another event fired when elements are added to the DOM? Or another way to sense changes to the DOM? Everything I've bumped into on similar issues with new markup additions, they have access to the callback function on .load() or similar, or they have a real javascript event to work with and live() works perfectly. Is this a pipe dream?

  • targeting sprites from a method in the document class - null object reference

    - by Freddyk
    Hi I am trying to code a flash app entirely in the document class. I am using GestureWorks with a touch screen. When a user essentially presses a button it calls a method that should hide a specific graphic but not the graphic they touched. Essentially I need a way to refer to a graphic on the screen using a method besides 'e.target'. //This code works because it can access 'e.target'. private function photo1SpriteFlickHandler(e:GestureEvent):void { var openTween:Tween = new Tween(e.target, "x", Strong.easeOut, 232, 970, 5, true); } //this code gives me a null object reference because I am using 'photo1Sprite' rather than 'e.target' private function photo1SpriteFlickHandler(e:GestureEvent):void { var openTween:Tween = new Tween(photo1Sprite, "x", Strong.easeOut, 232, 970, 5, true); } //photo1Sprite has already been programatically added to the screen as so: var photo1Sprite = new TouchSprite(); var photo1Loader=new Loader(); photo1Loader.load(new URLRequest("media/photos1/photo1.jpg")); photo1Loader.contentLoaderInfo.addEventListener(Event.COMPLETE,loaderComplete); photo1Sprite.x = 232; photo1Sprite.y = 538; photo1Sprite.scaleX = .3; photo1Sprite.scaleY = .3; photo1Sprite.blobContainerEnabled = true; photo1Sprite.addEventListener(TouchEvent.TOUCH_DOWN, startDrag_Press); photo1Sprite.addEventListener(TouchEvent.TOUCH_UP, stopDrag_Release); photo1Sprite.addChild(photo1Loader); addChild(photo1Sprite); So I can make photo1Sprite react if my method is attached to it directly using 'e.target' but not if I am trying to call it from a method that was called from another element on the screen.

  • How big can I make an Android application's canvas in terms of pixels?

    - by user279112
    I've determined an estimate of the size of my Android emulator's screen in pixels, although I think its resolution can be changed to other numbers. Quite frankly though that doesn't eliminate the general problem of not knowing how many pixels on each axis I have to work with on my Android applications in general. The main problem I'm trying to solve is this: How do I make sure I don't use a faulty resolution on Android applications if I want to keep things' sizes constant (so that if the application screen shrinks, for instances, objects will still show up just as big - there just won't be as many of them being shown) if I wish to do this with a single universal resolution for each program? Failing that, how do I make sure everything's alright if I try to do everything the same way with maybe a few different pre-set resolutions? Mainly it seems like a relevant question that must be answered before I can come across a complete answer for the general problem is how big can I always make my application in pixels, NOT regarding if and when a user resizes the application's screen to something smaller than the maximum size permitted by the phone and its operating system. I really want to try to keep this simple. If I were doing this for a modern desktop, for instance, I know that if I design the application with a 800x600 canvas, the user can still shrink the application to the point they're not doing themselves any favors, but at least I can basically count on it working right and not being too big for the monitor or something. Is there such a magic resolution for Android, assuming that I'm designing for API levels 3+ (Android 1.5+)? Thanks

    I have a function which gives me the complete file structure upto n-level, function getDirectory($path = '.', $ignore = '') { $dirTree = array (); $dirTreeTemp = array (); $ignore[] = '.'; $ignore[] = '..'; $dh = @opendir($path); while (false !== ($file = readdir($dh))) { if (!in_array($file, $ignore)) { if (!is_dir("$path/$file")) { //display of file and directory name with their modification time $stat = stat("$path/$file"); $statdir = stat("$path"); $dirTree["$path"][] = $file. " === ". date('Y-m-d H:i:s', $stat['mtime']) . " Directory == ".$path."===". date('Y-m-d H:i:s', $statdir['mtime']) ; } else { $dirTreeTemp = getDirectory("$path/$file", $ignore); if (is_array($dirTreeTemp))$dirTree = array_merge($dirTree, $dirTreeTemp); } } } closedir($dh); return $dirTree; } $ignore = array('.htaccess', 'error_log', 'cgi-bin', 'php.ini', '.ftpquota'); //function call $dirTree = getDirectory('.', $ignore); //file structure array print print_r($dirTree); Now here my requirement is , I have two sites The Development/Test Site- where i do testing of all the changes The Production Site- where I finally post all the changes as per test in development site Now, for example, I have tested an image upload in the Development/test site, and i found it appropriate to publish on Production site then i will completely transfer the Development/Test DB detail to Production DB, but now I want to compare the files structure as well to transfer the corresponding image file to Production folder. There could be the situation when I update the image by editing the image and upload it with same name, now in this case the image file would be already present there, which will restrict the use of "file_exist" logic, so for these type of situations....HOW CAN I COMPARE THE TWO FILE STRUCTURE TO GET THE SYNCHRONIZATION DONE AS PER REQUIREMENT??

  • Simple App Engine Sessions Implementation

    - by raz0r
    Here is a very basic class for handling sessions on App Engine: """Lightweight implementation of cookie-based sessions for Google App Engine. Classes: Session """ import os import random import Cookie from google.appengine.api import memcache _COOKIE_NAME = 'app-sid' _COOKIE_PATH = '/' _SESSION_EXPIRE_TIME = 180 * 60 class Session(object): """Cookie-based session implementation using Memcached.""" def __init__(self): self.sid = None self.key = None self.session = None cookie_str = os.environ.get('HTTP_COOKIE', '') self.cookie = Cookie.SimpleCookie() self.cookie.load(cookie_str) if self.cookie.get(_COOKIE_NAME): self.sid = self.cookie[_COOKIE_NAME].value self.key = 'session-' + self.sid self.session = memcache.get(self.key) if self.session: self._update_memcache() else: self.sid = str(random.random())[5:] + str(random.random())[5:] self.key = 'session-' + self.sid self.session = dict() memcache.add(self.key, self.session, _SESSION_EXPIRE_TIME) self.cookie[_COOKIE_NAME] = self.sid self.cookie[_COOKIE_NAME]['path'] = _COOKIE_PATH print self.cookie def __len__(self): return len(self.session) def __getitem__(self, key): if key in self.session: return self.session[key] raise KeyError(str(key)) def __setitem__(self, key, value): self.session[key] = value self._update_memcache() def __delitem__(self, key): if key in self.session: del self.session[key] self._update_memcache() return None raise KeyError(str(key)) def __contains__(self, item): try: i = self.__getitem__(item) except KeyError: return False return True def _update_memcache(self): memcache.replace(self.key, self.session, _SESSION_EXPIRE_TIME) I would like some advices on how to improve the code for better security. Note: In the production version it will also save a copy of the session in the datastore. Note': I know there are much more complete implementations available online though I would like to learn more about this subject so please don't answer the question with "use that" or "use the other" library.

  • JQuyer slide and stop issues: animated element freezes with quick mouse movement

    - by sherlock
    Here is Zi JsFiddle. In order to replicate my issue you have to hover over the link that says 'javascript', then mouseout that, then mouseback in. If you do this before the animation is complete, the pink slidedown #subMenu will freeze midway through sliding. Is there a way to prevent this from happening? I have tried some .stop()s , but i really don't want the animation to re-start every time you mouseenter or leave the .navLink . The animation should begin from where it left off. In other words, if the pink section is halfway down, and a slideDown() gets executed, the pink should not dissappear and then slide down, it should slide down from where it is. Thanks!! JS: $('header#subHeader').hide(); $('.navLink').hover(function () { if ($(this).children('div').length > 0) { var subMenu = $(this).find('.subMenu').html(); $('header#subHeader').empty().append('<div>' + subMenu + '</div>').stop().slideDown(); } else { $('header#subHeader').stop().slideUp(); } }); $('hgroup:first').on('mouseleave', function(){ $('header#subHeader').slideUp(); });
