  • GAE Task Queue oddness

    - by b3nw
    I have been testing the taskqueue with mixed success. Currently I am using the default queue, in default settings ect ect.... I have a test url setup which inserts about 8 tasks into the queue. With short order, all 8 are completed properly. So far so good. The problem comes up when I re-load that url twice under say a minute. Now watching the task queue, all the tasks are added properly, but only the first batch execute it seems. But the "Run in Last Minute" # shows the right number of tasks being run.... The request logs tell a different story. They show only the first set of 8 running, but all task creation urls working successfully. The oddness of this is that if I wait say a minute between the task creation url requests, it will work fine. Oddly enough changing the bucket_size or execution speed does not seem to help. Only the first batch are executed. I have also reduced the number of requests all the way down to 2, and still found only the first 2 execute. Any others added display the same issues as above. Any suggestions? Thanks

  • Problem comparing keys in Appengine/Python

    - by ana
    I'm trying to create a relationship between "tables" with Appengine/Python. Imagine I have a "table" for items, and a table for colors. I save the color of an item by saving the color key as an atribute of the item. That's working well, but this particular piece of code is not working: <select id="colorKey" name="colorKey"> {% for color in colors %} <option value="{{ color.key }}"{% if color.key = item.colorKey %} selected="selected"{% endif %}> {{ color.name }} - {{ item.colorKey }} - {{ color.key }} </option> {% endfor %} </select> Since the {{ item.colorKey }} and {{ color.key }} variables are actually the same chain of characters, I only can think in a problem with the types. {{ item.colorKey }} is a string for sure. But maybe {{ color.key }} is not?

  • Hudson: how do i use a parameterized build to do svn checkout and svn tag?

    - by Derick Bailey
    I'm setting up a parameterized build in hudson v1.362. the parameter i'm creting is used to determine which branch to checkout in subversion. I can set my svn repository url like this: https://my.svn.server/branches/${branch} and it does the checkout and the build just fine. now I want to tag the build after it finishes. i'm using the SVN tagging plugin for hudson to do this. so i go to the bottom of the project config screen for the hudson project and turn on "Perform Subversion tagging on successful build". here, i set my Tag Base URL to https://my.svn.server/tags/${branch}-${BUILD_NUMBER} and it gives me errors about those properties not being found. so i change them to environment variable usages like this: https://my.svn.server/tags/${env['branch']}-${env['BUILD_NUMBER']} and the svn tagging plugin is happy. the problem now is that my svn repository at the top is using the ${branch} syntax and the svn tagging plugin barfs on this: moduleLocation: Remote -https://my.svn.server/branches/$branch/ Tag Base URL: 'https://my.svn.server/tags/thebranchiused-1234'. There was no old tag at https://my.svn.server/tags/thebranchiused-1234. ERROR: Publisher hudson.plugins.svn_tag.SvnTagPublisher aborted due to exception java.lang.NullPointerException at hudson.plugins.svn_tag.SvnTagPlugin.perform(SvnTagPlugin.java:180) at hudson.plugins.svn_tag.SvnTagPublisher.perform(SvnTagPublisher.java:79) at hudson.tasks.BuildStepMonitor$3.perform(BuildStepMonitor.java:36) at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:601) at hudson.model.AbstractBuild$AbstractRunner.performAllBuildSteps(AbstractBuild.java:580) at hudson.model.AbstractBuild$AbstractRunner.performAllBuildSteps(AbstractBuild.java:558) at hudson.model.Build$RunnerImpl.cleanUp(Build.java:167) at hudson.model.Run.run(Run.java:1295) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:124) Finished: FAILURE notice the first line, there: the svn tag is looking at ${branch} as part of the repository url... it's not parsing out the property value. i tried to change my original Repository URL for svn to use the ${env['branch']} syntax, but that blows up on the original checkout because this syntax is not getting parsed at all by the checkout. help?! how do i use a parameterized build to set the svn url for checkout and for tagging my build?!

  • Exception in setDrawingCache in Android 1.5?

    - by sunil
    Hi, I am developing an application where I am using setDrawingCache and then once I get the Bitmap I destroy the cache by using destroyDrawingCache(). The application has been developed with Android SDK 1.6. When testing the application in emulator with Android 1.5 the application throws NullPointerException when try to manipulate the Bitmap returned by getDrawingCache(). It probably gives error since getDrawingCache returns null. The interesting thing in this is that the NullPointerException comes only after I run the application twice or thrice. It means I am able to get the Bitmap for two times and then it throws this exception. The error that I am getting is as below java.lang.NullPointerException E/AndroidRuntime( 1036): at com.babbleville.HomeScreenActivity.resizeBitmap(HomeScreenActivity.java: 394) E/AndroidRuntime( 1036): at com.babbleville.HomeScreenActivity.access $0(HomeScreenActivity.java:392) E/AndroidRuntime( 1036): at com.babbleville.HomeScreenActivity $1.handleMessage(HomeScreenActivity.java:327) E/AndroidRuntime( 1036): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 1036): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 1036): at android.app.ActivityThread.main(ActivityThread.java:3948) E/AndroidRuntime( 1036): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 1036): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 1036): at com.android.internal.os.ZygoteInit $MethodAndArgsCaller.run(ZygoteInit.java:782) E/AndroidRuntime( 1036): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:540) E/AndroidRuntime( 1036): at dalvik.system.NativeStart.main(Native Method) Can someone please let me know the problem?

    - by Cinaird
    I have a question, if i set a image height in css and try to get height/width i get different results in different browsers. Is there a way to get the same dimension in all browsers? You can find a live example here and the concept is like this: CSS: img{ height:100px; } Script: $(document).ready(function(){ $("#text").append($("#img_0").attr("height")); $("#text").append($("#img_0").attr("width")); }); Output Firefox: img height: 100 img width: 150 Output Chrome: img height: 100 img width: 0 Output Chrome: img height: 100 img width: 93? i have tried this from StackOverflow: stackoverflow.com/questions/1873419/jquery-get-height-width but still get the same result Any one know a good solution?

  • What's constitute an entry on the IPTables and how to find out which client it is originated from

    - by cbd
    I have a Billion BiPac 7700N Modem/Router/Access Point and I connect another router (TP-Link TL-WR1043ND) in wan-bypass mode to extend the wireless coverage. Lately, I noticed that the connection through TP-Link has been dropping out quite regularly. Having read some posts on the Internet, I checked system log on 7700N and found that there are many "nf_conntract: expectation table full" errors, which I suppose the iptables are full. My questions: What does constitute an entry on the iptable? Is it a client or a connection (which means one client can have multiple connections) How could I find out where are those connections originated from? Note: Many reported that the issue is usually related to having torrents running but I don't have any torrents running. Thank you.

  • Problems with jQuery load and getJSON only when using Chrome

    - by leftend
    I'm having an issue with two jQuery calls. The first is a "load" that retrieves HTML and displays it on the page (it does include some Javascript and CSS in the code that is returned). The second is a "getJSON" that returns JSON - the JSON returned is valid. Everything works fine in every other browser I've tried - except Chrome for either Windows or Mac. The page in question is here: http://urbanistguide.com/category/Contemporary.aspx When you click on a Restaurant name in IE/FF, you should see that item expand with more info - and a map displayed to the right. However, if you do this in Chrome all you get is the JSON data printed to the screen. The first problem spot is when the "load" function is called here: var fulllisting = top.find(".listingfull"); fulllisting.load(href2, function() { fulllisting.append("<div style=\"width:99%;margin-top:10px;text-align:right;\"><a href=\"#\" class=\"" + obj.attr("id") + "\">X</a>"); itemId = fulllisting.find("a.listinglink").attr("id"); ... In the above code, the callback function doesn't seem to get invoked. The second problem spot is when the "getJSON" function is called: $.getJSON(href, function(data) { if (data.error.length > 0) { //display error message } else { ... } In this case - it just seems to follow the link instead of performing the callback... and yes, I am doing a "return false;" at the end of all of this to prevent the link from executing. All of the rest of the code is inline on that page if you want to view the source code. Any ideas?? Thanks

  • Qt 4.6 Adding objects and sub-objects to QWebView window object (C++ & Javascript)

    - by Cor
    I am working with Qt's QWebView, and have been finding lots of great uses for adding to the webkit window object. One thing I would like to do is nested objects... for instance: in Javascript I can... var api = new Object; api.os = new Object; api.os.foo = function(){} api.window = new Object(); api.window.bar = function(){} obviously in most cases this would be done through a more OO js-framework. This results in a tidy structure of: >>>api ------------------------------------------------------- - api Object {os=Object, more... } - os Object {} foo function() - win Object {} bar function() ------------------------------------------------------- Right now I'm able to extend the window object with all of the qtC++ methods and signals I need, but they all have 'seem' to have to be in a root child of "window". This is forcing me to write a js wrapper object to get the hierarchy that I want in the DOM. >>>api ------------------------------------------------------- - api Object {os=function, more... } - os_foo function() - win_bar function() ------------------------------------------------------- This is a pretty simplified example... I want objects for parameters, etc... Does anyone know of a way to pass an child object with the object that extends the WebFrame's window object? Here's some example code of how I'm adding the object: mainwindow.h #ifndef MAINWINDOW_H #define MAINWINDOW_H #include <QtGui/QMainWindow> #include <QWebFrame> #include "mainwindow.h" #include "happyapi.h" class QWebView; class QWebFrame; QT_BEGIN_NAMESPACE class MainWindow : public QMainWindow { Q_OBJECT public: MainWindow(QWidget *parent = 0); private slots: void attachWindowObject(); void bluesBros(); private: QWebView *view; HappyApi *api; QWebFrame *frame; }; #endif // MAINWINDOW_H mainwindow.cpp #include <QDebug> #include <QtGui> #include <QWebView> #include <QWebPage> #include "mainwindow.h" #include "happyapi.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) { view = new QWebView(this); view->load(QUrl("file:///Q:/example.htm")); api = new HappyApi(this); QWebPage *page = view->page(); frame = page->mainFrame(); attachWindowObject(); connect(frame, SIGNAL(javaScriptWindowObjectCleared()), this, SLOT(attachWindowObject())); connect(api, SIGNAL(win_bar()), this, SLOT(bluesBros())); setCentralWidget(view); }; void MainWindow::attachWindowObject() { frame->addToJavaScriptWindowObject(QString("api"), api); }; void MainWindow::bluesBros() { qDebug() << "foo and bar are getting the band back together!"; }; happyapi.h #ifndef HAPPYAPI_H #define HAPPYAPI_H #include <QObject> class HappyApi : public QObject { Q_OBJECT public: HappyApi(QObject *parent); public slots: void os_foo(); signals: void win_bar(); }; #endif // HAPPYAPI_H happyapi.cpp #include <QDebug> #include "happyapi.h" HappyApi::HappyApi(QObject *parent) : QObject(parent) { }; void HappyApi::os_foo() { qDebug() << "foo called, it want's it's bar back"; }; I'm reasonably new to C++ programming (coming from a web and python background). Hopefully this example will serve to not only help other new users, but be something interesting for a more experienced c++ programmer to elaborate on. Thanks for any assistance that can be provided. :)

  • chrome extension login security with iframe

    - by Weaver
    I should note, I'm not a chrome extension expert. However, I'm looking for some advice or high level solution to a security concern I have with my chrome extension. I've searched quite a bit but can't seem to find a concrete answer. The situation I have a chrome extension that needs to have the user login to our backend server. However, it was decided for design reasons that the default chrome popup balloon was undesirable. Thus I've used a modal dialog and jquery to make a styled popup that is injected with content scripts. Hence, the popup is injected into the DOM o the page you are visiting. The Problem Everything works, however now that I need to implement login functionality I've noticed a vulnerability: If the site we've injected our popup into knows the password fields ID they could run a script to continuously monitor the password and username field and store that data. Call me paranoid, but I see it as a risk. In fact,I wrote a mockup attack site that can correctly pull the user and password when entered into the given fields. My devised solution I took a look at some other chrome extensions, like Buffer, and noticed what they do is load their popup from their website and, instead, embed an iFrame which contains the popup in it. The popup would interact with the server inside the iframe. My understanding is iframes are subject to same-origin scripting policies as other websites, but I may be mistaken. As such, would doing the same thing be secure? TLDR To simplify, if I embedded an https login form from our server into a given DOM, via a chrome extension, are there security concerns to password sniffing? If this is not the best way to deal with chrome extension logins, do you have suggestions with what is? Perhaps there is a way to declare text fields that javascript can simply not interact with? Not too sure! Thank you so much for your time! I will happily clarify anything required.

  • Advantages of Terminal Server instead of normal client-Server installation?

    - by Sam
    What are the advantages of using a (Windows) Terminal Server and thin clients instead of using a normal Server and full clients? So far I've only really used normal servers and clients, but now customers ask about terminal Server, and I'd like to know pro's and con's of using them instead of an "old-fashioned" client-server network. Some things I can guess: easier administration (don't need to install/update office/stuff on 20 computers but only on the server). Easier backup (no need to backup client computers). And I'd guess it would be hard (impossible) to connect and use local (like USB) hardware with Terminal Server? What else are the reasons for or against switching to Terminal Server?

  • Optimising RSS parsing on App Engine to avoid high CPU warnings

    - by Danny Tuppeny
    I'm pulling some RSS feeds into a datastore in App Engine to serve up to an iPhone app. I use cron to schedule updating the RSS every x minutes. Each task only parses one RSS feed (which has 15-20 items). I frequently get warnings about high CPU usage in the App Engine dashboard, so I'm looking for ways to optimise my code. Currently, I use minidom (since it's already there on App Engine), but I suspect it's not very efficient! Here's the code: dom = minidom.parseString(urlfetch.fetch(url).content) if dom: items = [] for node in dom.getElementsByTagName('item'): item = RssItem( key_name = self.getText(node.getElementsByTagName('guid')[0].childNodes), title = self.getText(node.getElementsByTagName('title')[0].childNodes), description = self.getText(node.getElementsByTagName('description')[0].childNodes), modified = datetime.now(), link = self.getText(node.getElementsByTagName('link')[0].childNodes), categories = [self.getText(category.childNodes) for category in node.getElementsByTagName('category')] ); items.append(item); db.put(items); def getText(self, nodelist): rc = '' for node in nodelist: if node.nodeType == node.TEXT_NODE: rc = rc + node.data return rc There isn't much going on, but the scripts often take 2-6 seconds CPU time, which seems a bit excessive for looping through 20ish items and reading a few attributes. What can I do to make this faster? Is there anything particularly bad in the above code, or should I change to another way of parsing? Are there are any libraries (that work on App Engine) that would be better, or would I be better parsing the RSS myself?

  • How do I send email in plain text rather than HTML in my email client?

    - by JS Bangs
    For various reasons, I often have to help friends and family to send email in plain text rather than HTML. However, many of them use email clients that I'm not familiar with, forcing me to search the internet, read help files, or click randomly through dialogs looking for the setting. I've often wished there was a single page that included instructions for changing this setting for every popular email client. So let's make one. Write instructions for changing email settings from plain text to HTML in your preferred email client below. If someone else has already done so, please upvote their description so that the most used email clients rise to the top. (For obvious reasons, there won't be an "accepted answer" for this question. I'll set this question to community wiki after a few days.)
