How to call a SOAP webservice with a simple String (xml in string format)
|
<p>I have this string representing a XML: </p>
<pre><code>String soapCall="<soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding"> <soap:Body xmlns:m="http://www.example.org/stock"> <m:addDownloadParams> <m:idApp>";
soapCall+=idApp;
soapCall+="<m:versionApp>";
soapCall+=versonApp;
soapCall+="</m:versionApp> <m:os>Android</m:os> </m:addDownloadParams> </soap:Body> </soap:Envelope>";
</code></pre>
<p>And i have this soap webservice: </p>
<pre><code>http://stats.mywebsite.com/ws/adddownload
</code></pre>
<p>Now, i need to pass that string to that soap webservice on android, but i dont know the way, i know i need to use httpcliente:</p>
<pre><code>HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
</code></pre>
<p>but i dont know how to call the soapwebservice with that string.</p>
<p>Anyone haves a code example? i can't find it on google. I dont want to use a library, i need to do it by myself</p>
<p>Thanks</p>
<p><strong>EDIT: this is the code now, but it is not working, i get error 500 internal server error:</strong></p>

ExpressJS/Typescript - Unabe to Retrieve ZoneAwarePromise value?

<p><strong>UPDATE 1 STARTS</strong></p>
<p>Issue is that I am not able to get all the cities and locations in sequence once I draw the FormArray again and this is becuase of the loop only. Anyways, I am new to TS, you might understand much better. Thanks again.</p>

<h2><strong>UPDATE 1 ENDS</strong></h2>
<p>I am using TypeScript in MeanStack and using a function with <strong>async</strong> because it was not working in sequential order</p>
<pre><code>// Calling Function (In Main.ts file)
let rs = getVPDetails("2132");
// Function Definition (In Main.ts file)
async getVPDetails(pid) {
let res = await this.vpService.getPlansInfo({plan_id: pid});
return res;
}
// Middle Ware (IN service.ts file)
getPlansInfo(data) {
return new Promise((resolve, reject) => {
this.http.post('/vehicle-plan/plan-info', data)
.map(res => res.json())
.subscribe(res => {
resolve(res);
}, (err) => {
reject(err);
});
});
}
</code></pre>
<p>I am getting the exact value while returning res (in "return res;") as I require. But in rs (Where I call), I am getting a value like this:</p>
<p>ZoneAwarePromise {__zone_symbol__state: null, __zone_symbol__value: Array(0)}</p>
<p>In __zone_symbol__value I am having my data as I require but by no means I am able to access it. I know that I am breaking the Promise object but how can I resolve it exactly when I dont want to use then() in getVPDetails();</p>
<p>Please let me know what am I missing OR how can I get the data I require. </p>
<p>Thanks in advance.</p>

How to use QThread correctly in pyqt with moveToThread()?

<p>i read this article <a href="http://mayaposch.wordpress.com/2011/11/01/how-to-really-truly-use-qthreads-the-full-explanation/" rel="noreferrer">How To Really, Truly Use QThreads; The Full Explanation</a>, it says instead of subclass qthread, and reimplement run(), one should use moveToThread to push a QObject onto QThread instance using moveToThread(QThread*)</p>
<p>here is the c++ example, but i don't know how to convert it to python code.</p>
<pre class="lang-cpp prettyprint-override"><code>class Worker : public QObject

};

worker->moveToThread(&workerThread);
connect(workerThread, SIGNAL(finished()), worker, SLOT(deleteLater()));

What's the correct way to implement AsyncTask? static or non static nested class?
|
<p>The "Login" from Android examples implemented <code>AsyncTask</code> as a non-static inner class. However, according to Commonsguys, this class should be static and use weak-reference to the outside activity <a href="http://commonsware.com/blog/2010/09/10/asynctask-screen-rotation.html">see this</a>.</p>
<p>So what is the correct way to implement <code>AsyncTask</code>? Static or non-static?</p>

ReferenceError: Parse is not defined

How to click a particular button within a window (without using XPOS YPOS)
|
<p>I have just started using AUTOHOTKEY and its been phenomenal.I have a doubt though.
I want to automate the launching of an application and then clicking on a specific button in it.I would like to accomplish this using AHK.</p>
<p>Once I launch the applicaton this window appears <a href="https://www.dropbox.com/s/vkmoccc4hhhxmng/LOGIN%20screenshot.jpg" rel="nofollow">here</a>.
I want to hit the "Connect" button, but I cant figure out a good way to move the cursor to the connect button. I tried the following code which uses tab.</p>
<pre><code>Loop ,5
{
sleep 2*1000
Send {Tab down}
}
</code></pre>
<p><strong>This works, But i feel this is crude and need a better way. Is there a way to use button_name or button_text to my advantage?</strong> </p>
<p><strong>I dont want to use screen positions XPOS AND YPOS either.</strong></p>

Binding Path Fill to Button Foreground in ContentPresenter
|
<p>I have a Button Style with a Template containing a ContentPresenter, in which I am attempting to bind the Fill of a Path to the Foreground of a button:</p>
<pre><code><!-- This is inside the template of a button style -->
<ContentPresenter>
<ContentPresenter.Resources>
<Style TargetType="{x:Type Path}">
<Setter Property="Fill" Value="{Binding Path=Foreground, RelativeSource={RelativeSource AncestorType=Button}}"/>
</Style>
</ContentPresenter.Resources>
</ContentPresenter>
</code></pre>
<p>I also have a Path with no Fill set, that I can reference in the button as the content, like so:</p>
<pre><code><Button Style="{DynamicResource MyButtonStyle}" Content="{DynamicResource PathIcon}" Foreground="Blue"/>
</code></pre>
<p>I would expect the Path inside the button to be blue, but it isn't... it doesn't grab the foreground from the button.</p>
<p>How can I get the Path to bind to the color of the button?</p>
<p>Thank you!</p>
<p>P.S.:</p>
<p>If I put a hardcoded color in the Value (i.e. Value="Red"), the Path inside the button is red... so I know that works...</p>
<pre><code><ContentPresenter>
<ContentPresenter.Resources>
<Style TargetType="{x:Type Path}">
<Setter Property="Fill" Value="Red"/>
</Style>
</ContentPresenter.Resources>
</ContentPresenter>
</code></pre>
<hr>
<p>Edit:</p>
<p>Here is the complete Style and ControlTemplate:</p>
<pre><code><Style x:Key="Button_Style" TargetType="{x:Type Button}">
<Setter Property="Foreground" Value="{StaticResource White_Brush}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid x:Name="grid" Background="Transparent">
<ContentPresenter>
<ContentPresenter.Resources>
<Style TargetType="{x:Type Path}">
<Setter Property="Fill" Value="{Binding Path=Foreground, RelativeSource={RelativeSource AncestorType=Button}}"/>
</Style>
</ContentPresenter.Resources>
</ContentPresenter>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<!-- Should affect Text as well as Paths in the Content property of the button! -->
<Setter Property="Foreground" Value="{StaticResource Black_Brush}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

SonarLint plugin not working in Eclipse Oxygen
|
<p>I am trying to get SonarLint plugin working in Eclipse but I am not having much luck.
More specifically, I don't see any issues detected or highlighted in the "SonarLint On-the-fly" tab when looking at a simple Java class in a Java project.</p>
<p>I use the following software.</p>
<p><strong>OS</strong>: </p>
<p>Win 10 Pro - Version 1709</p>
<p><strong>Java</strong>: </p>
<p>java version "1.8.0_161"</p>
<p>Java(TM) SE Runtime Environment (build 1.8.0_161-b12)</p>
<p>Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)</p>
<p><strong>Eclipse</strong>:</p>
<p>Version: Oxygen.3 Release (4.7.3)</p>
<p>Sonar software: </p>
<p><strong>SonarLint Eclipse plugin</strong>: </p>
<p>org.sonarlint.eclipse.site-3.4.0
source: <a href="https://www.sonarlint.org/eclipse/" rel="nofollow noreferrer">https://www.sonarlint.org/eclipse/</a></p>
<p><strong>SonarQube</strong>:</p>
<p>SonarQube 7.0
source: <a href="https://www.sonarqube.org/downloads/" rel="nofollow noreferrer">https://www.sonarqube.org/downloads/</a></p>
<p><strong>SonarScanner</strong>:</p>
<p>sonar-scanner-3.1.0.1141
source: <a href="https://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Scanner" rel="nofollow noreferrer">https://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Scanner</a> (Windows 64 bit - link)</p>
<p>I downloaded the SonarLint Eclipse plugin and successfully installed it in Eclipse. I can see all the SonarLint tabs and configuration options. </p>
<p>I downloaded and successfully setup SonarQube server (localhost on the default port 9000). I also downloaded and set up Sonar Scanner. </p>
<p>I created a simple Java project in Eclipse and I created a Java class in it. I added the sonar-project.properties file to the Java project. </p>
<p><strong>sonar-project.properties</strong></p>
<pre><code># must be unique in a given SonarQube instance
sonar.projectKey=sp
# this is the name and version displayed in the SonarQube UI. Was mandatory prior to SonarQube 6.1.
sonar.projectName=Simple Project
sonar.projectVersion=1.0
# Path is relative to the sonar-project.properties file. Replace "\" by "/" on Windows.
# This property is optional if sonar.modules is set.
sonar.sources=.
# Encoding of the source code. Default is default system encoding
#sonar.sourceEncoding=UTF-8
</code></pre>
<p>My Eclipse Java project looks like this:</p>
<p><a href="https://i.stack.imgur.com/3lavt.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3lavt.png" alt="enter image description here"></a></p>
<p>I have set up my project bindings successfully.</p>
<p><a href="https://i.stack.imgur.com/ybZ4a.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ybZ4a.png" alt="enter image description here"></a></p>
<p>I can start the SonarQube and login without issues.
I navigated to the location of my "Simple Project" in Windows Explorer and opened a Windows PowerShell from there.</p>
<p>I executed the command <strong>sonar-scanner</strong> in the Windows PowerShell which successfully scanned the <strong>Simple Project</strong> and I can see the results in my SonarQube server.</p>
<p><a href="https://i.stack.imgur.com/2dnkQ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2dnkQ.png" alt="enter image description here"></a></p>
<p>So all is good so far. BUT... There is no indication of issues in Eclipse. I don't see any issues under the SonarLint On-the-fly tab in Eclipse.</p>
<p><a href="https://i.stack.imgur.com/Zi0F9.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Zi0F9.png" alt="enter image description here"></a></p>
<p>I do have "Run SonarLint automatically" enabled (checked) and I also tried to manually analyze the App.java file by <em>right-clicking on the file > SonarLint > Analyze</em>.</p>
<p>I see no issues underlined in either the code or listed in the "SonarLint On-the-fly" tab. I must be missing a step somewhere. Could anyone please give me any tips how to get the automatic SonarLint issue detection working in Eclipse?</p>
<p>Thank you!</p>

Ant script: Have <exec> tag dump out entire command line
|
<p>I have an ant build script with a fairly complex <code><exec></code> command with lots of <code><arg></code> tags that I'm trying to troubleshoot. I was wondering if it is possible to view the entire command line after ant has constructed it; either in the eclipse debugger or maybe by dumping it to a file.</p>

JtaTransactionManager no rollback after failed commit during "flush"
|
<p><br/>
<strong>Update:</strong> I was testing it with Bitronix TM and it rollbacks perfectly, so the issue is in JBoss TM (arjuna) or in my configuration.
<br/></p>
<p><strong>Update 2:</strong> It looks like transactions are not global, I've tried different datasources, Bitronix datasource has <em>allowLocalTransactions</em> property and after setting it my application throws an exception that something tried to use it in local mode. If I use Bitronix with this datasource it works without any errors. I believe there is something wrong in configs.</p>
<p>I have an issue with JTA transactions. I'm using Tomcat 7 + Hibernate 4 + Spring 3 + JBoss TS 4 and JTA transactions.</p>
<p>Suppose there is the following method:</p>
<pre><code>@Transactional(propagation = Propagation.REQUIRED)
public void testMethod() {
insertOfSomeNewEntityInstance();
updateOfAnotherEntity();
}
private void insertOfSomeNewEntityInstance() {
SomeEntity entity = new SomeEntity();
someEntityDAO.save(entity);
}
private void updateOfAnotherEntity() {
AnotherEntity anotherEntity = anotherEntityDAO.findBySomeProperty(1L);
anotherEntity.incrementSomeValue();
anotherEntityDAO.save(anotherEntity);
}
</code></pre>
<p>If this method throws <em>"org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect)"</em> during "updateOfAnotherEntity()" method execution or any other runtime exception that might happen during "flush" (Hibernate also shows: <em>HHH000346: Error during managed flush [Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect)</em>.
then the result of insertOfSomeNewEntityInstance() execution is not rolled back.</p>
<p>After debugging this issue I found "doCommit" method in org.springframework.transaction.jta.JtaTransaction Manager</p>
<pre><code>@Override
protected void doCommit(DefaultTransactionStatus status) {
JtaTransactionObject txObject = (JtaTransactionObject) status.getTransaction();
try {
int jtaStatus = txObject.getUserTransaction().getStatus();
if (jtaStatus == Status.STATUS_NO_TRANSACTION) {
throw new UnexpectedRollbackException("JTA transaction already completed - probably rolled back");
}
if (jtaStatus == Status.STATUS_ROLLEDBACK) {
try {
txObject.getUserTransaction().rollback();
}
catch (IllegalStateException ex) {
if (logger.isDebugEnabled()) {
logger.debug("Rollback failure with transaction already marked as rolled back: " + ex);
}
}
throw new UnexpectedRollbackException("JTA transaction already rolled back (probably due to a timeout)");
}
txObject.getUserTransaction().commit();
}
catch (RollbackException ex) {
throw new UnexpectedRollbackException(
"JTA transaction unexpectedly rolled back (maybe due to a timeout)", ex);
}
catch (HeuristicMixedException ex) {
throw new HeuristicCompletionException(HeuristicCompletionException.STATE_MIXED, ex);
}
catch (HeuristicRollbackException ex) {
throw new HeuristicCompletionException(HeuristicCompletionException.STATE_ROLLED_BACK, ex);
}
catch (IllegalStateException ex) {
throw new TransactionSystemException("Unexpected internal transaction state", ex);
}
catch (SystemException ex) {
throw new TransactionSystemException("JTA failure on commit", ex);
}
}
</code></pre>
<p>If "txObject.getUserTransaction().commit();" fails with RollbackException then this method throws UnexpectedRollbackException and here is the part of org.springframework.transaction.support.AbstractPl atformTransactionManager processCommit(...) that catches it:</p>
<pre><code>}
catch (UnexpectedRollbackException ex) {
// can only be caused by doCommit
triggerAfterCompletion(status, TransactionSynchronization.STATUS_ROLLED_BACK);
throw ex;
}
</code></pre>
<p>I do not see any rollbacks in triggerAfterCompletion() method and after this method everything else just cleans up resources.</p>
<p><strong>To sum up</strong>, spring/jboss just commits the result of insertOfSomeNewEntityInstance(), fails to execute updateOfAnotherEntity() because of concurrent modification error, and does not rollback anything. If I manually throw any runtime or checked exception from updateOfAnotherEntity() it rollbacks correctly, the issue occurs only when Hibernate throws some runtime exception during "flush".</p>

Angular 2 Routing with Home Page
|
<p>I am learning Angular2 Routing and try to display the Welcome Page.
My app has three pages</p>
<ul>
<li>Welcome Page (it's just a blank page with just links to other Routes)</li>
<li>Home Page - Some texts and Description</li>
<li>Todo List Page - List of ToDos</li>
</ul>
<p>The problem is that I cannot manage to display the Welcome Page. It automatically loads Home page and show the content from the HomeComponent by default.</p>
<p>As shown in the screenshot, I want to display only 2 links. I want to load the content from Home/Todo only when it is clicked. But by default, it goes to localhost:xxx/Home and load the Home page.</p>
<p><a href="https://i.stack.imgur.com/Dj7Ev.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Dj7Ev.png" alt="enter image description here"></a></p>
<p>I tried to set the '' blank path to AppComponent as below, but it loads AppComponent twice and shows the links two times.</p>
<pre><code>{ path: '', component: AppComponent, pathMatch: 'full' },
</code></pre>

Cakephp 3.0.3 How do I use the default layout?
|
<p>I just installed cakephp 3.0.3 with composer and I am running the built in development cake server to view my site. I have only made two changes to the project. After working with the project for a little while, I realized the default.ctp layout is not loading on my pages.</p>
<p>The first thing I did was configure the database connection to MySQL. The next thing I wanted to do was include bootstrap and jQuery. Naturally, I followed the cakephp cookbook and put the css and js in their appropriate folders under webroot. Next I linked to those files in src/Templates/Layout/default.ctp. </p>
<p>At first when they did not show up, I guessed it must have been an issue with the command linking them, but when I tried to add other content to be displayed within default.ctp, I realized that the layout is not rendering at all.</p>
<p>I am totally new to cakephp and php, but I read straight from the cookbook and just followed their example, I don't know why the default layout would not be loaded at all.</p>
<p>I tried to change the appController to include <code>$this->layout = 'default';</code> as suggested <a href="https://stackoverflow.com/questions/7426469/assigning-layout-in-cakephp">here</a> but that just gave me a strict error saying that appController beforeRender() must be compatible with Controller beforeRender() so I just changed it back to the way it was by default.</p>
<p>I am using OS X Yosemite and Google Chrome to view the page if that makes a difference. Everything on the default homepage has check marks saying that everything is installed and configured properly, and I have seen other people that have similar issues where mod_rewrite is their problem but I do not have any errors about mod_rewrite.</p>
<p>Here is my default.ctp:</p>

Get PDF hyperlinks on iOS with Quartz
|
<p>I've spent all day trying to get hyperlinks metadata from PDFs in my iPad application.
The CGPDF* APIs are a true nightmare, and the only piece of information I've found on the net about all this is that I have to look for an "Annots" dictionary, but I just can't find it in my PDFs. </p>
<p>I even used the old <a href="https://github.com/below/PDF-Voyeur/network" rel="nofollow noreferrer">Voyeur Xcode sample</a> to inspect my test PDF file, but no trace of this "Annots" dictionary...</p>
<p>You know, this is a feature I see on every PDF reader - this same question has <a href="https://stackoverflow.com/questions/93297/newbie-wants-to-create-a-pdf-reader-for-ipod-touch-whats-the-best-approach">been</a> <a href="https://stackoverflow.com/questions/3257057/iphone-cgpdfdocument-pdf-links">asked</a> <a href="https://stackoverflow.com/questions/2609602/pdf-hyperlinks-on-iphone-ipad">multiple</a> <a href="https://stackoverflow.com/questions/1247792/how-to-access-hyperlinks-in-pdf-documents-iphone">times</a> here with no real practical answers. I usually never ask for sample code directly but apparently this time I really need it... anyone got this working, possibly with sample code?</p>
<p><strong>Update</strong>: I just realized the guy who has done my testing PDF had just inserted an URL as text, and not a real annotation. He tried putting an annotation and my code works now... But that's not what I need, so it seems I'll have to analyze text and search for URLs. But that's another story... </p>
<p><strong>Update 2</strong>: So I finally came up with some working code. I'm posting it here so hopefully it'll help someone. It assumes the PDF document actually contains annotations. </p>
<pre><code>for(int i=0; i<pageCount; i++) {
CGPDFPageRef page = CGPDFDocumentGetPage(doc, i+1);
CGPDFDictionaryRef pageDictionary = CGPDFPageGetDictionary(page);
CGPDFArrayRef outputArray;

return;

int arrayCount = CGPDFArrayGetCount( outputArray );
if(!arrayCount) {
continue;

return;
}

if(!CGPDFObjectGetValue(rectObj, kCGPDFObjectTypeReal, &coord)) {
return;
}
coords[k] = coord;
}
char *uriString = (char *)CGPDFStringGetBytePtr(uriStringRef);
NSString *uri = [NSString stringWithCString:uriString encoding:NSUTF8StringEncoding];
CGRect rect = CGRectMake(coords[0],coords[1],coords[2],coords[3]);
CGPDFInteger pageRotate = 0;
CGPDFDictionaryGetInteger( pageDictionary, "Rotate", &pageRotate );
CGRect pageRect = CGRectIntegral( CGPDFPageGetBoxRect( page, kCGPDFMediaBox ));
if( pageRotate == 90 || pageRotate == 270 ) {
CGFloat temp = pageRect.size.width;
pageRect.size.width = pageRect.size.height;
pageRect.size.height = temp;
}
rect.size.width -= rect.origin.x;
rect.size.height -= rect.origin.y;
CGAffineTransform trans = CGAffineTransformIdentity;
trans = CGAffineTransformTranslate(trans, 0, pageRect.size.height);
trans = CGAffineTransformScale(trans, 1.0, -1.0);
rect = CGRectApplyAffineTransform(rect, trans);
// do whatever you need with the coordinates.
// e.g. you could create a button and put it on top of your page
// and use it to open the URL with UIApplication's openURL

ui-bootstrap-tpls failed to load template
|
<p>I've inherited an angular project, and it's having problems loading the ui-bootstrap-tpls modules.</p>
<p>For each directive it's trying to use from bootstrap, I get something similar to the following:</p>
<p>Error: [$compile:tpload] Failed to load template: template/datepicker/popup.html</p>
<p>I've read about the need to include the tpls version of the ui-bootstrap lib. (ui-bootstrap-tpls-0.10.0.js (instead of ui-bootstrap.js)), but having done that as well as every permutation of module injected into my module as a dependency (ui.bootstrap, ui.bootstrap.tpls, template/datepicker/datepicker.html'), but I can't beat it.</p>

ConstraintViolationException when trying to persist

<p>I get the following error whenever I try to persist a child objects to a existing father object in JPA:</p>

<p>My DAO class for Sucursal looks like this:</p>
<pre><code>@Stateless

} else {
update(sucursal);
}
}
// ...
}
</code></pre>
<p>Whenever I click on a save button in front end it calls this method:</p>
<pre><code>public void guardar() {
System.out.println(newSucursal.getDireccion());
System.out.println(newSucursal.getTelefono());
for (int i = 0; i < listproductos.size(); i++) {
// listproductos.get(i).setSucursal(newSucursal);
System.out.println(listproductos.get(i).toString());
newSucursal.getProductos().add(listproductos.get(i));
}
sucursalDAO.save(newSucursal);
}
</code></pre>
<p>When I call this save method I add the new child <strong>Productos</strong> to my <strong>Sucursales</strong> but when I try to persist the Parent it give me the error I posted above.
I have tried many things but cant seem to figure out what the problem is?
Is there another way of saving child entities to existing parent entities?</p>
<p><strong>EDIT</strong></p>
<p>This is the code that fixed my problem for my save method:</p>
<pre><code>public void guardar() {
System.out.println(newSucursal.getDireccion());
System.out.println(newSucursal.getTelefono());
for (int i = 0; i < listproductos.size(); i++) {
listproductos.get(i).setSucursal(newSucursal);
Categoria cat = new Categoria();
cat = categoriaDAO.read(listproductos.get(i).getCategoria().getId());
listproductos.get(i).setCategoria(cat);
Subcategoria subcat = new Subcategoria();
subcat = subcategoriaDAO.read(listproductos.get(i).getSubcategoria().getId());
listproductos.get(i).setSubcategoria(subcat);
System.out.println(listproductos.get(i).toString());
newSucursal.getProductos().add(listproductos.get(i));
}
// newSucursal.setProductos(listproductos);
sucursalDAO.save(newSucursal);

jQuery: Clearing Form Inputs
|
<p>I have tried to different ways to clear a form:</p>
<pre><code><form action="service.php" id="addRunner" name="addRunner" method="post">
First Name: <input type="text" name="txtFirstName" id="txtFirstName" /><br />
Last Name: <input type="text" name="txtLastName" id="txtLastName" /><br />
Gender: <select id="ddlGender" name="ddlGender"><option value="">--Please Select--</option>
<option value="f">Female</option>
<option value="m">Male</option>
</select><br />
Finish Time:
<input type="text" name="txtMinutes" id="txtMinutes" size="10" maxlength="2">(Minutes)
<input type="text" name="txtSeconds" id="txtSeconds" size="10" maxlength="2">(Seconds)
<br />
<button type="submit" name="btnSave" id="btnSave">Add Runner</button>
<input type="hidden" name="action" value="addRunner" id="action">
</form>
</code></pre>
<p>jQuery #1:</p>
<pre><code>function clearInputs(){
$("#txtFirstName").val('');
$("#txtLastName").val('');
$("#ddlGender").val('');
$("#txtMinutes").val('');
$("#txtSeconds").val('');
}
</code></pre>
<p>This works perfectly.</p>
<p>jQuery #2:</p>
<pre><code>function clearInputs(data){
$("#addRunner :input").each(function(){
$(this).val('');
});
</code></pre>
<p>This clears the form but does not let me submit any more any information to it. I try and click the button again and it does nothing.</p>
<p>Here's the button click handler:</p>
<pre><code>$("#btnSave").click(function(){
var data = $("#addRunner :input").serializeArray();
$.post($("#addRunner").attr('action'), data, function(json){
if (json.status == "fail"){
alert(json.message);
}
if (json.status == "success"){
alert(json.message);
clearInputs();
}
}, "json");
});
</code></pre>
<p>PHP Post code:</p>
<pre><code><?php
if($_POST){
if ($_POST['action'] == 'addRunner') {
$fname = htmlspecialchars($_POST['txtFirstName']);
$lname = htmlspecialchars($_POST['txtLastName']);
$gender = htmlspecialchars($_POST['ddlGender']);

<p>If I use jQuery method #2, I get this error in the console:</p>
<pre><code>Uncaught TypeError: Cannot read property 'status' of null
</code></pre>
<p>Why does this happen?</p>
<p>I forgot to include this key information:</p>
<pre><code>function fail ($message){
die(json_encode(array('status'=>'fail', 'message'=>$message)));
}
function success ($message){
die(json_encode(array('status'=>'success', 'message'=>$message)));
</code></pre>
<p>This sends the message back to the AJAX function in jQuery. It looks like after I submit the form once using method #2 the success/fail messages are blanked out.</p>

Accessing Keys from Linux Input Device
|
<h2>What I am trying to do</h2>
<p>So, I have been trying to access keyboard input in Linux. Specifically, I need to be able to access modifier key presses <strong>without</strong> other keys being pressed. Furthermore, I want to be able to do this <strong>without</strong> an X system running.</p>
<p>So, in short, my requirements are these:</p>
<ul>
<li>Works on Linux</li>
<li>Does not need X11</li>
<li>Can retrieve modifier key press <strong>without</strong> any other keys being pressed
<ul>
<li>This includes the following keys:
<ul>
<li>Shift</li>
<li>Control</li>
<li>Alt</li>
</ul></li>
<li>All I need is a simple <code>0 = not pressed</code>, <code>1 = currently pressed</code> to let me know if
the key is being held down when the keyboard is checked</li>
</ul></li>
</ul>
<h2>My computer setup</h2>
<p>My normal Linux machine is on a truck towards my new apartment; so, I only have a Macbook Air to work with right now. Therefore, I am running Linux in a VM to test this out.</p>
<p><strong>Virtual Machine in VirtualBox</strong></p>
<ul>
<li>OS: Linux Mint 16</li>
<li>Desktop Environment: XFCE</li>
</ul>
<p>Everything below was done in this environment. I've tried both with X running and in one of the other ttys.</p>
<h2>My Thoughts</h2>
<p>I'll alter this if someone can correct me.</p>
<p>I've done a fair bit of reading to realize that higher-level libraries do not provide this kind of functionality. Modifier keys are used with other keys to provide an alternate key code. Accessing the modifier keys themselves through a high-level library in Linux isn't as easy. Or, rather, I haven't found a high-level API for this on Linux. </p>
<p>I thought <a href="http://www.leonerd.org.uk/code/libtermkey/" rel="noreferrer" title="Link to the library">libtermkey</a> would be the answer, but it doesn't seem to support the Shift modifier key any better than normal keystroke retrieval. I'm also not sure if it works without X.</p>
<p>While working with libtermkey (before I realized it didn't get shift in cases like Shift-Return), I was planning to write a daemon that would run to gather keyboard events. Running copies of the daemon program would simply pipe requests for keyboard data and receive keyboard data in response. I could use this setup to have something always running in the background, in case I cannot check key code statuses at specific times (have to be receive key codes as they happen).</p>
<p>Below are my two attempts to write a program that can read from the Linux keyboard device. I've also included my small check to make sure I had the right device.</p>
<h2>Attempt #1</h2>
<p>I have tried to access the keyboard device directly, but am encountering issues. I have tried the suggestion <a href="https://stackoverflow.com/a/4225290" title="Stack Overflow suggestion">here</a> that is in another Stack Overflow thread. It gave me a segmentation fault; so, I changed it from fopen to open:</p>
<pre><code>// ...
int fd;
fd = open("/dev/input/by-path/platform-i8042-serio-0-event-kbd", O_RDONLY);
char key_map[KEY_MAX/8 + 1];
memset(key_map, 0, sizeof(key_map));
ioctl(fd, EVIOCGKEY(sizeof key_map), key_map);
// ...
</code></pre>
<p>While there was no segmentation fault, there was no indicator of any key press (not just modifier keys). I tested this using:</p>
<pre><code>./foo && echo "TRUE" || echo "FALSE"
</code></pre>
<p>I've used that to test for successful return codes from commands quite a lot; so, I know that's fine. I've also outputted the key (always 0) and mask (0100) to check. It just doesn't seem to detect anything.</p>
<h2>Attempt #2</h2>
<p>From here, I thought I'd try a slightly different approach. I wanted to figure out what I was doing wrong. Following <a href="http://baruch.siach.name/blog/posts/linux_input_keys_status/" rel="noreferrer" title="Linux Input Key Status">this</a> page providing a snippet demonstrating printing out key codes, I bundled that into a program:</p>
<pre><code>#include <stdio.h>
#include <stdint.h>
#include <string.h>
#include <fcntl.h>
#include <linux/input.h>
int main(int argc, char** argv) {
uint8_t keys[128];
int fd;
fd = open("/dev/input/by-path/platform-i8042-serio-event-kbd", O_RDONLY);
for (;;) {
memset(keys, 0, 128);
ioctl (fd, EVIOCGKEY(sizeof keys), keys);
int i, j;
for (i = 0; i < sizeof keys; i++)
for (j = 0; j < 8; j++)
if (keys[i] & (1 << j))
printf ("key code %d\n", (i*8) + j);
}
return 0;
}
</code></pre>
<p>Previously, I had the size to 16 bytes instead of 128 bytes. I should honestly spend a bit more time understanding ioctl and EVIOCGKEY. I just know that it supposedly maps bits to specific keys to indicate presses, or something like that (<strong>correct me if I'm wrong, please!</strong>).</p>
<p>I also didn't have a loop initially and would just hold down various keys to see if a key code appeared. I received nothing; so, I thought a loop might make the check easier to test in case a missed something.</p>
<h2>How I know the input device is the right one</h2>
<p>I tested it by running <code>cat</code> on the input device. Specifically:</p>
<pre><code>$ sudo cat /dev/input/by-path/platform-i8042-serio-0-event-kbd
</code></pre>
<p>Garbage ASCII was sent to my terminal on key press and release events starting with the return (enter) key when I began the output using cat. I also know that this seems to work fine with modifier keys like shift, control, function, and even Apple's command key on my Macbook running a Linux VM. Output appeared when a key was pressed, began to appear rapidly from subsequent signals sent by holding the key down, and outputted more data when a key was released.</p>
<p>So, while my approach may not be the right one (I'm willing to hear <strong>any</strong> alternative), the device seems to provide what I need.</p>
<p>Furthermore, I know that this device is just a link pointing to /dev/input/event2 from running:</p>
<pre><code>$ ls -l /dev/input/by-path/platform-i8042-serio-0-event-kbd
</code></pre>
<p>I've tried both programs above with /dev/input/event2 and received no data. Running cat on /dev/input/event2 provided the same output as with the link.</p>

Block Check-In on Policy Failure
|
<p>I've created the check-in policy <a href="https://msdn.microsoft.com/en-us/library/bb668980.aspx" rel="nofollow noreferrer">from this MSDN article</a> as an example (code is just copy / pasted).</p>
<p>This works fine, it appears when I try and do a check-in, however it appears as an warning. So I can ignore it by just pressing Check In again. How can I change the code, as listed in the URL, so that it will return an Error not a warning. I can't see any properties on PolicyFailure to do this.</p>
<p>Essentially I want it to look like the error in this screenshot:
<img src="https://i.stack.imgur.com/oHXIT.png" alt="enter image description here"></p>
<p><sup><a href="http://blogs.msmvps.com/vstsblog/2014/05/13/turning-off-policy-overrides-in-tfs/" rel="nofollow noreferrer">Image Source</a></sup></p>
<p><strong>EDIT:</strong> Here is the exact code that I'm using. Now it is slightly modified from the original source, but not in any massive way I wouldn't have thought. Unfortunately I can't post screenshots, but I'll try and describe everything I've done.</p>
<p>So I have a DLL from the code below, I've added it into a folder at C:\TFS\CheckInComments.dll. I added a registry key under Checkin Policies with the path to the DLL, the string value name is the same as my DLL (minus .dll). In my project settings under source control I've added this Check-In Policy.</p>
<p>It all seems to work fine, if I try and do a check-in it will display a warning saying "Please provide some comments about your check-in" which is what I expect, what I'd like is for it to stop the check-in if any policies are not met, however I would still like the user to be able to select Override if necessary. At the moment, even though there is a warning, if I was to click the Check In button then it would successfully check-in the code.</p>
<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Microsoft.TeamFoundation.VersionControl.Client;

How do I get jqGrid to work using ASP.NET + JSON on the backend?
|
<p>ok, I'm back. I totally simplified my problem to just three simple fields and I'm still stuck on the same line using the addJSONData method. I've been stuck on this for days and no matter how I rework the ajax call, the json string, blah blah blah...I can NOT get this to work! I can't even get it to work as a function when adding one row of data manually. Can anyone PLEASE post a working sample of jqGrid that works with ASP.NET and JSON? Would you please include 2-3 fields (string, integer and date preferably?) I would be happy to see a working sample of jqGrid and just the manual addition of a JSON object using the addJSONData method. Thanks SO MUCH!! If I ever get this working, I will post a full code sample for all the other posting for help from ASP.NET, JSON users stuck on this as well. Again. THANKS!! </p>

Warning Prop `href` did not match. using react server-side-rendering
|
<p>I am using <code>react-router-dom</code> and I am guessing that this is causing the problem, but I have no clue where to even start looking or how to fix it. I also am getting errors like <code>Warning: Did not expect server HTML to contain a <nav> in <div></code>.</p>
<p>As I stated, I'm not really sure where to look so if you think there is certain code that would be helpful please let me know and I will post it. Otherwise, I can post my code that I use to do SSR.</p>
<p><strong>EDIT</strong>: Exact error: <code>Warning: Prop</code>href<code>did not match. Server: "/profile/5a073dc44cb45b00125e5c82" Client: "profile/5a073dc44cb45b00125e5c82"</code></p>
<p>I have checked the client and it has <code>/profile/:id</code> so not sure where it says there is not a <code>/</code>, as for the other error with the <code><nav></code> in <code><div></code> , I have a <code>nav</code> inside my header , but I'm not really sure how to go about "fixing" that.</p>

Deleting File and Directory in JUnit
|
<p>I'm writing a test for a method that creates a file in a directory. Here's what my JUnit test looks like:</p>
<pre><code> @Before
public void setUp(){
objectUnderTest = new ClassUnderTest();
//assign another directory path for testing using powermock
WhiteBox.setInternalState(objectUnderTest, "dirPathField", mockDirPathObject);
nameOfFile = "name.txt";
textToWrite = "some text";
}
@Test
public void shouldCreateAFile(){
//create file and write test
objectUnderTest.createFile(nameOfFile, textToWrite);
/* this method creates the file in mockPathObject and performs
FileWriter.write(text);
FileWriter.close();
*/
File expect = new File(mockPathObject + "\\" + nameOfFile);
assertTrue(expect.exist());
//assert if text is in the file -> it will not be called if first assert fails
}
@After
public void tearDown(){
File destroyFile = new File(mockPathObject + "\\" + nameOfFile);
File destroyDir = new File(mockPathObject);
//here's my problem
destroyFile.delete(); //why is this returning false?
destroyDir.delete(); //will also return false since file was not deleted above
}
</code></pre>
<p>I was able to delete the File using deleteOnExit() but I will not be able to delete the directory using delete or deleteOnExit. I will also perform other test for other scenarios in this test script so I don't want to use deleteOnExit.</p>
<p>I don't know why I cannot delete it in JUnit test script while I can delete a file created and modified by FileWriter in runtime when the code is not a JUnit test. I also tried performing an infiniteLoop after the test method and delete the file manually but it tells me that other program is still using the file though I'm able to modify its content.</p>
<p>Hope somebody can suggest a way to delete the files and directories created during the tests. Thanks :D</p>
<p>For more clarity, the method I test looks like this <a href="https://stackoverflow.com/questions/11878716/unit-testing-method-that-invokes-filewriter">Unit testing method that invokes FileWriter</a></p>
<p>Edit:Here is the method to test</p>
<pre><code> public void createFile(String fileName, String text){
//SOME_PATH is a static string which is a field of the class
File dir = new File(SOME_PATH); //I modified SOME_PATH using whitebox for testing
if(!dir.exists()){
booelan createDir = dir.mkdirs();
if(!createDir){
sysout("cannot make dir");
return;
}
}
try{
FileWriter fileWrite = new FileWriter(dir.getAbsolutePath() + "/" + fileName, true);
fileWrite.write(text);
fileWrite.close();
}
catch(Exception e){
e.printStackTrace();
}
}
</code></pre>
<p>I cannot modify this method as other developers created it. I was just instructed to create unit tests for test automation. Thanks.</p>

GDB won't load source file
|
<ol>
<li>I'm using <code>arm-linux-gcc</code> to compile a simple C file at host (debian i386) with <code>-g</code>.</li>
<li>Then copy the <code>a.out</code> file to the target (arm,uclibc) computer.</li>
<li>Run the <code>a.out</code> – it's just ok.</li>
<li>Use GDB (target) <code>gdb a.out</code> and list the source code, it says <code>No such file or directory</code>.
The fact has always been so?</li>
<li>If I copy the <code>1.c</code> file to the target, then <code>list</code> command it lists the source code.</li>
</ol>
<p>My Question:</p>
<h3>GDB has always been so, or there are other options I can control?</h3>
<h3>Do you have any suggestions to debug the program?</h3>
<p>Some information maybe is useful:</p>
<p><strong>source code 1.c file</strong>:</p>
<pre><code>#include <stdio.h>
#include <string.h>
#include <stdlib.h>
// main function
int main(void)
{
int i;
for(i=0;i<3;i++){
printf("i=%d\n",i);
}
return 0;
}

How to use a RegExp literal as object key?
|
<p>I would like to use create a object that contains regular expressions as the key value. I tried to use the following syntax:</p>
<pre><code>var kv = {
/key/g : "value"
};
</code></pre>
<p>But it fails according <a href="http://www.javascriptlint.com/">JavaScript lint</a>:</p>
<pre><code>SyntaxError: invalid property id
</code></pre>
<p>How can I fix it?</p>
<h3>Update</h3>
<p>Background: The reason why I want to do this is to implement a workaround that fixes wrong unicode in a HTTP API result. I know this is very hackish, but since I have no control over the API server code I think this is the best I can do.</p>
<p>Currently I implemented the mapping by having a keys array and a values array:</p>
<pre><code>function fixUnicode(text) {
var result = text;
var keys = [];
var values = [];
keys.push(/&Atilde;&copy;/g); values.push("&eacute;");
keys.push(/&Atilde;&uml;/g); values.push("&egrave;");
keys.push(/&Atilde;&ordf;/g); values.push("&ecirc;");
keys.push(/&Atilde;&laquo;/g); values.push("&euml;");
keys.push(/&Atilde;&nbsp;/g); values.push("&agrave;");
keys.push(/&Atilde;&curren;/g); values.push("&auml;");
keys.push(/&Atilde;&cent;/g); values.push("&acirc;");
keys.push(/&Atilde;&sup1;/g); values.push("&ugrave;");
keys.push(/&Atilde;&raquo;/g); values.push("&ucirc;");
keys.push(/&Atilde;&frac14;/g); values.push("&uuml;");

How to .Scan() a MySQL TIMESTAMP value into a time.Time variable?
|
<p>I have this Go code:</p>
<pre><code>package main
import (
"fmt"
"database/sql"
_"github.com/go-sql-driver/mysql"
"time"
)
type User struct {
id uint32
name string
email string
rating uint8
subscription uint8
date_registered time.Time
online string
}
// main entry point
func main() {
// setup db connection
db, err := sql.Open("mysql", "user:@tcp(127.0.0.1:3306)/c9?parseTime=true")
if err != nil {
fmt.Println(err)
}
defer db.Close()
// query
rows, err := db.Query("SELECT * FROM users WHERE id = ?", 1)
if err != nil {
fmt.Println(err)
}
defer rows.Close()
usr := User{}
for rows.Next() {
err := rows.Scan(&usr.id, &usr.name, &usr.email, &usr.rating, &usr.subscription, &usr.date_registered, &usr.online)
if err != nil {
fmt.Println(err)
}
}
fmt.Println(usr)
err = rows.Err()
if err != nil {
fmt.Println(err)
}
}
</code></pre>
<p>This is what I get from MySQL console:</p>
<pre><code>mysql> describe users;
+-----------------+---------------------+------+-----+-------------------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------------+---------------------+------+-----+-------------------+----------------+
| id | int(10) unsigned | NO | PRI | NULL | auto_increment |
| name | varchar(50) | NO | | NULL | |
| email | varchar(50) | NO | | NULL | |
| rating | tinyint(3) unsigned | YES | | NULL | |
| subscription | tinyint(3) unsigned | NO | | 0 | |
| date_registered | timestamp | NO | | CURRENT_TIMESTAMP | |
| online | char(1) | NO | | N | |
+-----------------+---------------------+------+-----+-------------------+----------------+
7 rows in set (0.00 sec)
mysql> SELECT * FROM users;
+----+------------+-----------------------+--------+--------------+---------------------+--------+
| id | name | email | rating | subscription | date_registered | online |
+----+------------+-----------------------+--------+--------------+---------------------+--------+
| 1 | alakhazamm | abcdefghhhh@gmail.com | NULL | 0 | 2014-10-28 15:37:44 | N |
+----+------------+-----------------------+--------+--------------+---------------------+--------+
1 row in set (0.00 sec)
</code></pre>
<hr>
<p>After <code>.Scan()</code>, <code>fmt.Println(usr)</code> prints</p>
<pre><code>{1 alakhazamm abcdefghhhh@gmail.com 0 0 {0 0 <nil>} }
</code></pre>
<p>The last two fields of the struct are wrong but I have no idea why.
I've tried using <code>date_registered string</code> in the struct definition, but I get an empty string after <code>.Scan()</code>.
I've also read in the driver's docs that <code>?parseTime=true</code> parses MySQL DATE and DATETIME values into time.Time, but they don't mention TIMESTAMP which is what I'm currently using.</p>
<p>Am I missing something important or is it a bug/missing feature of the library?</p>

Under Spring Framework: WARN: WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader)
|
<p>I have spent all day trying to solve the logging problem I'm having with log4j in a webapp. No matter what I do, I cannot get rid of the following:</p>
<pre><code>log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
</code></pre>
<p>Just to be clear, I have read all of the articles here on Stack Overflow addressing this issue. I've read the log4j manual. I've been through a dozen different tutorials. I've tried the properties approach and the XML approach (log4j.properties and log4j.xml, respectively). Also, I have confirmed that the log4j.xml file is being read. Aside from the fact that the server tells me so during startup, I can influence the level of feedback through the .xml file. So, yes, the log4j.xml file is in the CLASSPATH.</p>

<p>What needs to be done now is I need to create a method that will search through the tree to find the binary code (011001 etc) to the specific character. What is the best way to do this? I thought maybe I would do a normal search through the tree as if it were an AVL tree going to the right if its bigger or left if it's smaller. </p>
<p>But because the nodes don't use ints doubles etc. but only using objects that contain characters as strings or null to signify its not a leaf but only a root. The other option would be to do an in-order run through to find the leaf that I'm looking for but at the same time how would I determine if I went right so many times or left so many times to get the character.</p>
<pre><code>package huffman;
public class Frequency implements Comparable {
private String s;
private int n;
public Frequency left;
public Frequency right;
Frequency(String s, int n)
{
this.s = s;
this.n = n;
}
public String getString()
{
return s;
}
public int getFreq()
{
return n;
}
public void setFreq(int n)
{
this.n = n;
}
@Override
public int compareTo(Object arg0) {
Frequency other = (Frequency)arg0;
return n < other.n ? -1 : (n == other.n ? 0 : 1);
}
}
</code></pre>
<p>What I'm trying to do is find the binary code to actually get to each character. So if I were trying to encode <code>aabbbcccc</code> how would I create a string holding the binary code for a going left is 0 and going right is 1. </p>
<p>What has me confused is because you can't determine where anything is because the tree is obviously unbalanced and there is no determining if a character is right or left of where you are. So you have to search through the whole tree but if you get to a node that isn't what you are looking for, you have backtrack to another root to get to the other leaves.</p>

Transpose of a sparse matrix in C++
|
<p>I am very new to C++. Here, I am trying to find out transpose of a sparse matrix. Here is the code:</p>
<pre><code>#include<iostream>
using namespace std;
class transposeM{
int m1[20][20],m2[20][20],i,j,row,column,t;

cout<<"enter the number of column: \n";
cin>>column;
for(i=0;i<row;i++){
for(j=0;j<column;j++){
cin>>m1[i][j];
if(m1[i][j]){
t++;
// cout<<"first t is:"<<t;
//if non zero
m2[t][0]=i+1;
m2[t][1]=j+1;
m2[t][2]=m1[i][j];
}
}
}
m2[0][0]=row;
m2[0][1]=column;
m2[0][2]=t;

int main(int argc,char ** argv){
transposeM obj;
obj.read();
obj.display();

<p>Output:</p>
<pre><code>Enter the number of row:

2 2 2
1 2 1
2 1 2
Transpose is:
2 2 2
2 1 2
1 2 1

<p>But something went wrong; read matrix and convert the same to sparse matrix is fine. But finding out transpose got some logical error.</p>

View layout doesn't refresh on orientation change in android
|
<p>I'd like my VIEW layout to be adjusted on orientation change.</p>
<p>My Manifest is set up with: <code>android:configChanges="keyboardHidden|orientation"</code> on the activity.</p>
<p>I have <code>res/layout-land</code>, <code>res/layout-port</code>.</p>
<p>I have <code>onConfigurationChanged</code> in my <code>Activity</code> (it get's called on rotation).</p>
<p>In my <code>Activity</code> I have a <code>ViewFlipper</code> and inside it I have <code>LinearLayouts</code>.</p>
<p>When I START the <code>Activity</code> in port or land mode, the View's layout is correct (according
to my <code>res/layout-????</code> files).</p>
<p>But when I'm already in the <code>Activity</code> and I rotate the phone, then my View layout is not changed. The screen is rotated, and the <code>onCreate</code> of the activity is not called, as it's supposed to be, the <code>onConfigurationChanged</code> is called in the <code>Activity</code>, but the screen is always redrawn with the <code>LinearLayout</code> that was loaded when the <code>Activity</code> started.</p>
<p>I have a feeling that I miss out something in the <code>onConfigurationChanged</code>, but don't know what. I guess I need to call some function on the <code>ViewFlipper</code> or on the <code>LinearLayout</code> that's inside. What functions should I call?</p>
<pre><code>ViewFlipper flipper;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
flipper = new ViewFlipper(getApplicationContext());
setContentView(flipper);
initLayout();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
setContentView(flipper);
}
void initLayout() {
MyView myview = createMyView(0);
flipper.addView(myview, 0);
myview = createMyView(1);
flipper.addView(myview, 1);
myview = createMyView(1);
flipper.addView(myview, 1);
}
</code></pre>
<p>I tried to add <code>flipper = new ViewFlipper(getApplicationContext());</code> to <code>onConfigurationChanged()</code> but that made everything black after rotation. I guess I'll have to call initLayout, but that would recalculate everything (and that's exactly what I don't want to do, and that's why I'm trying to do it with <code>onConfigurationChanged</code>, as opposed to the android default "dropMyActivity & createANewActivity"</p>
<p><strong>SOLUTION:</strong>
Previously I thought I can trigger the layout to be refreshed on rotation, but it seems I have to re-create the layout with the current context (after the orientation change)</p>
<pre><code>@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
setContentView(R.layout.category_flipper);
ViewFlipper oldFlipper = viewFlipper;
viewFlipper = (ViewFlipper)findViewById(R.id.categoryFlipper);
for (int i = 0; i < 3; i++) {
final CardLayout cl = new CardLayout(this, cardData[i]);
viewFlipper.addView(cl);
}
cardData[viewIndex].restorePlayer();
viewFlipper.setDisplayedChild(viewIndex);
oldFlipper.removeAllViews();
}

How to cast object to type described by Type class?
|
<p>I have a object:</p>
<pre><code>ExampleClass ex = new ExampleClass();
</code></pre>
<p>And:</p>
<pre><code>Type TargetType
</code></pre>
<p>I would like to cast ex to type described by TargetType like this:</p>
<pre><code>Object o = (TargetType) ex;
</code></pre>
<p>But when I do this I get:</p>
<blockquote>
<p>The type or namespace name 't' could
not be found</p>
</blockquote>
<p>So how to do this? Am I missing something obious here?</p>
<p>Update:</p>
<p>I would like to obtain something like this:</p>
<pre><code>public CustomClass MyClassOuter
{
get
{
return (CustomClass) otherClass;
}
}
private otherClass;
</code></pre>
<p>And because I will have many properties like this I would like do this:</p>
<pre><code>public CustomClass MyClassOuter
{
get
{
return (GetThisPropertyType()) otherClass;
}
}
private SomeOtherTypeClass otherClass;
</code></pre>
<p>Context:</p>
<p>Normally in my context in my class I need to create many properties. And in every one replace casting to the type of property. It does not seem to have sense to me (in my context) because I know what return type is and I would like to write some kind of code that will do the casting for me. Maybe it's case of generics, I don't know yet. </p>
<p>It's like I can assure in this property that I get the right object and in right type and am 100% able to cast it to the property type. </p>
<p>All I need to do this so that I do not need to specify in every one property that it has to "cast value to CustomClass", I would like to do something like "cast value to the same class as this property is".</p>
<p>For example:</p>
<pre><code>class MYBaseClass
{
protected List<Object> MyInternalObjects;
}
class MyClass
{
public SpecialClass MyVeryOwnSpecialObject
{
get
{
return (SpecialClass) MyInteralObjects["MyVeryOwnSpecialObject"];
}
}
}
</code></pre>
<p>And ok - I can make many properties like this one above - but there is 2 problems: </p>
<p>1) I need to specify name of object on MyInternalObjects but it's the same like property name. This I solved with System.Reflection.MethodBase.GetCurrentMethod().Name.</p>
<p>2) In every property I need to cast object from MyInternalObjects to different types. In MyVeryOwnSpecialObject for example - to SpecialClass. It's always the same class as the property.</p>
<p>That's why I would like to do something like this:</p>
<pre><code>class MYBaseClass
{
protected List<Object> MyInternalObjects;
}
class MyClass
{
public SpecialClass MyVeryOwnSpecialObject
{
get
{
return (GetPropertyType()) MyInteralObjects[System.Reflection.MethodBase.GetCurrentMethod().Name];
}
}
}
</code></pre>
<p>And now concerns: Ok, what for? Because further in my application I will have all benefits of safe types and so on (intellisense).</p>
<p>Second one: but now you will lost type safety in this place? No. Because I'm very sure that I have object of my type on a list.</p>

How to properly copy/clone DOM element and then paste/insert it as HTML element in Angular.js?
|
<p>So I've got such big webapp that uses Angular.js.<br />Small part of this webapp has sidebar which, currently, displays two div containers: one that shows user profile stats (thumbnail, reputation, messages, some skills .etc) and second which is slider (angular-ui) carousel showing some images.</p>
<p>What I want to do, is to clone this whole skills sidebar and paste this cloned DOM object into slider as another slide, but converted into HTML element.</p>
<p>Here's code of this slider:</p>
<pre><code><div id="scrolling-sidebar">
<carousel interval="myInterval">
<slide ng-repeat="slide in slides" active="slide.active">
<a href="{{slide.link}}" ng-if="$index != 1">
<img ng-src="{{slide.image}}" />
</a>
<a href="{{slide.link}}" ng-bind-html="slide.content"></a>
</slide>
</carousel>
</div>
</code></pre>
<p>Here's part of this whole sidebar controller .coffee script:</p>
<pre><code>'use strict'
angular.module('someApp')
.controller 'SidebarCtrl', ($scope, $modal, $http, $location, settings) ->
$scope.myInterval = 5000
$scope.slides = [
{
image: "/images/_getpro_banners1.png"
link: "#/get-pro"
}
{
content: $("#profile-skills-sidebar").clone()
link: "#/get-pro"
}
{
image: "/images/_getpro_banners2.png"
link: "#/get-pro"
}
{
image: "/images/_getpro_banners3.png"
link: "#/get-noticed"
}
{
image: "/images/_getpro_banners4.png"
link: "#/get-pro"
}
{
image: "/images/_getpro_banners5.png"
link: "#/get-pro"
}
{
image: "/images/_getpro_banners6.png"
link: "#/get-pro"
}
{
image: "/images/_getpro_banners7.png"
link: "#/get-pro"
}
]
console.log "Cloned dom element: " + $scope.slides[1].content[0].html()
</code></pre>
<p>When running this webapp (basically refreshing webpage), I get following error in developer console: <code>TypeError: Cannot read property 'html' at new <anonymous> (http://127.0.0.1:9000/scripts/controllers/sidebar.js:39:69) of undefined</code> which corresponds to this line <code>console.log("Cloned dom element: " + $scope.slides[1].content[0].html());</code> in compiled to js sidebar.js file.</p>
<p>So this basically means, that this line <code>content: $("#profile-skills-sidebar").clone()</code> doesn't work like intended - it looks like the DOM element isn't even cloned.</p>
<p>Thus, second slide is <code>[object Object]</code> instead copied skills bar.</p>
<p>I got jQuery loaded in (using bower and grunt for frontend development), I can use in while in browser devtools:</p>
<pre><code>> var skills = $("#profile-skills-sidebar");
< undefined
> skills
< [<div id="profile-skills-sidebar">…</div>]
> skills[0]
< <div id="profile-skills-sidebar">…</div>
</code></pre>
<p>I tried creating directive in .coffee script:</p>
<pre><code>.directive "skillsBarSlide", ['$compile', ($scope, $compile, $timeout) ->
restrict: 'A'
#template: '<a href="{{slide.link}}"></a>'
link: (scope, elem, attrs) ->
$timeout( ->
scope.slides[1].content = angular.element($("#profile-skills-sidebar")).copy()
element.append($compile(scope.slides[1].content)(scope))
)
]
</code></pre>
<p>but it didn't worked.</p>
<p>So what steps precisely I have to make to:<br />
1. clone needed DOM element<br />
2. Probably convert it to string of HTML elements (because cloned DOM will be an object)<br />
3. Insert into desired div container</p>
<p>I know that I need here probably $sce, $compile maybe $sanitize (I've read the angular docs a bit), but I'm fresh to angular, didn't understood it well yet.</p>
<p>Thanks for eventual help.</p>

<p>I was playing with docker and mounted my local mysql to a docker container and connected MySql-Workbench so I could view the DB (experimenting) here is the command I ran.</p>
<pre><code>docker run -d --name alldb-mysql -v /var/lib/mysql:/var/lib/mysql -e MYSQL_USER=root -e MYSQL_PASSWORD=password -p 3306:3306 mysql:latest
</code></pre>
<p>after I stopped my container and removed it, I can't start/restart mysql (local install). when I run <code>sudo /etc/init.d/mysql start</code> it returns </p>
<pre><code>[....] Starting mysql (via systemctl): mysql.serviceJob for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
failed!
</code></pre>
<p>so I checked <code>systemctl status mysql.service</code></p>

<p>By the looks of this, I (well docker did) managed to changed the owner and group of all the directories in mysql directory.</p>
<p><strong>Do I need to do a complete reinstall of MySQL Server?</strong></p>
<p><strong>What is the simplest, easiest way to fix this?</strong></p>
<p>your help will be much appreciated.</p>
<p><strong>Updated with FIX</strong></p>
<blockquote>
<p>Just what Andy Shinn said in point one, I just ran <code>sudo chown -R
mysql:mysql /var/lib/mysql</code> to change the owner back and started mysql
by running <code>sudo /etc/init.d/mysql start</code> and mysql returned </p>
<p><code>[ ok ]Starting mysql (via systemctl): mysql.service.</code></p>

HTTP/1.1 401 Unauthorized in Response Headers in Load runner for GET Requests

<p>I am new to Load runner , Am facing am issue while play back of the script</p>
<p>LR 12.50</p>
<p>O.S Windows 7 SP2</p>
<p>Protocol is Mobile HTTP/HTML</p>
<p>Recording mode is Proxy</p>
<p>Let me explain my scenario</p>
<p>While executing following function:</p>
<pre><code> web_custom_request("authenticate",
"URL=https://ws-xx.xxx.com/tcs/rest/authenticate?include=user,company",
"Method=POST",

</code></pre>
<p>For the above POST method , am getting response as below </p>
<pre><code> HTTP/1.1 200 OK\r\n

<p>I refereed <a href="http://www.sqaforums.com/showflat.php?Number=645138" rel="nofollow noreferrer">this link</a>.</p>
<p>My understanding from the above custom request , login is success but the next
subsequent requests are getting failed.</p>
<p>I have used web_cleanup_cookies() function but didn't solve the issue .</p>
<p>I tried to capture the Cookie ID using the below function</p>
<pre><code>web_reg_save_param("COOKIE_ID",

web_add_header("Cookie",lr_eval_string("{COOKIE_ID}"));
</code></pre>
<p>Now question is where to place parameter "COOKIE_ID" in my script while there is </p>
<p>no value in script for COOKIE_ID?</p>
<p>How to handle this issue ? Can anybody please help me .</p>

Top 1 on Left Join SubQuery
|
<p>I am trying to take a person and display their current insurance along with their former insurance. I guess one could say that I'm trying to flaten my view of customers or people. I'm running into an issue where I'm getting multiple records back due to multiple records existing within my left join subqueries. I had hoped I could solve this by adding "TOP 1" to the subquery, but that actually returns nothing...</p>
<p>Any ideas?</p>

How can I fix Laravel 5.1 - 404 Not Found?
|
<p>I am trying to use Laravel 5.1 for the first time. I was able to install it and <code>https://sub.example.com/laravel/public/</code> is displaying what is should. However, views I create are giving me a 404 error Page not found.</p>
<p>Here is what I have done so far:</p>
<p>I created a controller in <code>laravel\app\Http\controllers\Authors.php</code></p>
<p>Here is the code behind the <code>Authors.php</code> file</p>
<pre><code><?php
class Authors_Controller extends Base_Controller {
public $restful = true;
public function get_index() {
return View::make('authors.index')
->with('title', 'Authors and Books')
->with('authors', Author::order_by('name')->get());
}
}
</code></pre>
<p>Then I created a view in <code>laravel\resources\views\Authors\index.blade.php</code></p>
<p>Here is the code behind the <code>index.blade.php</code> file</p>
<pre><code>@layout('layouts.default')
@section('content')
Hello, this is a test
@endsection
</code></pre>
<p>Then I created a layout in <code>laravel\resources\views\layouts\default.blade.php</code></p>
<p>Here is the code behind the <code>default.blade.php</code> file</p>
<pre><code><!DOCTYPE html>
<html>
<head>
<title>{{ $title }}</title>
</head>
<body>
@if(Session::has('message'))
<p style="color: green;">{{ Session::get('message') }}</p>
@endif
@yield('content')
Hello - My first test
</body>
</html>
</code></pre>
<p>Finally I created a route in <code>laravel\app\Http\routes.php</code></p>
<pre><code><?php
Route::get('/', function () {
return view('welcome');
});
Route::get('authors', array('as'=>'authors', 'uses'=>'authors@index'));
</code></pre>
<p>But for some reason I keep getting 404 error Page not found.</p>
<p>I enabled the mod_rewrite on my Apache 2.4.9 by uncommenting out the line</p>
<pre><code>LoadModule rewrite_module modules/mod_rewrite.so
</code></pre>
<p>Then restarted Apache.</p>
<p>From what I can tell in the <code>php_info()</code> output the mod_rewrite is enabled</p>
<pre><code>Loaded Modules
core mod_win32 mpm_winnt http_core mod_so mod_php5 mod_access_compat mod_actions mod_alias mod_allowmethods mod_asis mod_auth_basic mod_authn_core mod_authn_file mod_authz_core mod_authz_groupfile mod_authz_host mod_authz_user mod_autoindex mod_cgi mod_dir mod_env mod_include mod_isapi mod_log_config mod_mime mod_negotiation mod_rewrite mod_setenvif mod_socache_shmcb mod_ssl
</code></pre>
<p>My current .htaccess file looks like this "which is the factory default"</p>
<p>
Options -MultiViews
</p>
<pre><code>RewriteEngine On
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</code></pre>
<p></p>
<p>I have also tried to change it to the code below as per the <a href="http://laravel.com/docs/5.1" rel="nofollow noreferrer">documentation</a>:</p>
<pre><code>Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</code></pre>
<p>However, I am still getting the 404 page when I go to</p>
<pre><code>https://sub.example.com/laravel/public/authors
</code></pre>
<p>What am I doing wrong?
How can I fix this problem?</p>

spring-boot datasource profiles w/ application.properties
|
<p><strong><em>Updated Question based upon feedback:</em></strong></p>
<p>I have a spring-boot application that has three databases: H2 for integration testing, and Postgresql for qa & production. Since spring-boot creates a default datasource for you, I don't have anything defined for my integration tests. I thought I would use application.properties to define my datasource connection values but I am not certain what is the best way to handle this. </p>
<p>I have two files:</p>
<p><strong>src/main/resources/application.properties</strong></p>
<pre><code>spring.profiles.active=production
appName = myProduct
serverPort=9001
spring.datasource.url=jdbc:postgresql://localhost/myDatabase
spring.datasource.username=user
spring.datasource.password=password
spring.datasource.driverClassName=org.postgresql.Driver
spring.jpa.hibernate.hbm2ddl.auto=update
spring.jpa.hibernate.ejb.naming_strategy=org.hibernate.cfg.EJB3NamingStrategy
spring.jpa.hibernate.show_sql=true
spring.jpa.hibernate.format_sql=true
spring.jpa.hibernate.use_sql_comments=false
spring.jpa.hibernate.type=all
spring.jpa.hibernate.disableConnectionTracking=true
spring.jpa.hibernate.default_schema=dental
</code></pre>
<p><strong>src/main/resources/application-test.properties</strong></p>
<pre><code>spring.profiles.active=test
serverPort=9002
spring.datasource.url = jdbc:h2:~/testdb
spring.datasource.username = sa
spring.datasource.password =
spring.datasource.driverClassName = org.h2.Driver
liquibase.changeLog=classpath:/db/changelog/db.changelog-master.sql
</code></pre>
<p>I used to run my tests with with gradle (using "gradle build test") or within IntelliJ. I updated my gradle file to use:</p>
<pre><code>task setTestEnv {
run { systemProperty "spring.profiles.active", "test" }
}
</code></pre>
<p>But when I run <strong>gradle clean build setTestEnv test</strong> I get errors that seem to indicate the test is trying to connect to an actual Postgresql database: </p>

How do I scroll in tmux using the mouse?
|
<p>I'm using tmux 1.8 on Mac OS X 1.9.3 in the Terminal.app with an Apple magic mouse. I'm also using oh-my-zsh.</p>
<p>I can't scroll at all with the mouse when tmux is running. It just scrolls the whole terminal window up which goes beyond the output of tmux.</p>

<pre><code>set -g mode-mouse on

C# Parallel Vs. Threaded code performance
|
<p>I've been testing the performance of System.Threading.Parallel vs a Threading and I'm surprised to see Parallel taking longer to finish tasks than threading. I'm sure it's due to my limited knowledge of Parallel, which I just started reading up on.</p>
<p>I thought i'll share few snippets and if anyone can point out to me paralle code is running slower vs threaded code. Also tried to run the same comparison for finding prime numbers and found parallel code finishing much later than threaded code.</p>
<pre><code>public class ThreadFactory
{
int workersCount;
private List<Thread> threads = new List<Thread>();
public ThreadFactory(int threadCount, int workCount, Action<int, int, string> action)
{
workersCount = threadCount;
int totalWorkLoad = workCount;
int workLoad = totalWorkLoad / workersCount;
int extraLoad = totalWorkLoad % workersCount;
for (int i = 0; i < workersCount; i++)
{
int min, max;
if (i < (workersCount - 1))
{
min = (i * workLoad);
max = ((i * workLoad) + workLoad - 1);
}
else
{
min = (i * workLoad);
max = (i * workLoad) + (workLoad - 1 + extraLoad);
}
string name = "Working Thread#" + i;
Thread worker = new Thread(() => { action(min, max, name); });
worker.Name = name;
threads.Add(worker);
}
}
public void StartWorking()
{
foreach (Thread thread in threads)
{
thread.Start();
}
foreach (Thread thread in threads)
{
thread.Join();
}
}
}
</code></pre>
<p>Here is the program:</p>
<pre><code>Stopwatch watch = new Stopwatch();
watch.Start();
int path = 1;
List<int> numbers = new List<int>(Enumerable.Range(0, 10000));
if (path == 1)
{
Parallel.ForEach(numbers, x =>
{
Console.WriteLine(x);
Thread.Sleep(1);
});
}
else
{
ThreadFactory workers = new ThreadFactory(10, numbers.Count, (min, max, text) => {
for (int i = min; i <= max; i++)
{
Console.WriteLine(numbers[i]);
Thread.Sleep(1);
}
});
workers.StartWorking();
}
watch.Stop();
Console.WriteLine(watch.Elapsed.TotalSeconds.ToString());
Console.ReadLine();
</code></pre>
<p><strong>Update:</strong></p>
<p>Taking Locking into consideration: I tried the following snippet. Again the same results, Parallel seems to finish much slower.</p>
<p>path = 1;
cieling = 10000000;</p>
<pre><code> List<int> numbers = new List<int>();
if (path == 1)
{
Parallel.For(0, cieling, x =>
{
lock (numbers)
{
numbers.Add(x);
}
});
}
else
{
ThreadFactory workers = new ThreadFactory(10, cieling, (min, max, text) =>
{
for (int i = min; i <= max; i++)
{
lock (numbers)
{
numbers.Add(i);
}
}
});
workers.StartWorking();
}
</code></pre>
<p><strong>Update 2:</strong>
Just a quick update that my machine has Quad Core Processor. So Parallel have 4 cores available.</p>

</code></pre>
<p>Apache version 2.4.4</p>
<p>Everything must be ok, but... no. When I tried to insert a integer value (like 87 or 1) in the "nivel" field, mysql give me the next error:</p>
<p><code>"No se pudo insertar Data truncated for column 'nivel' at row 1 1integer"</code>, like the comment I wrote in the code.</p>
<p>("No se pudo insertar" means "Cannot insert").</p>
<p>As you can see, I forced the variable $nivel as integer, and PHP recognice correctly (that's the reason I put $nivel and $muestra in the die sentence). I tried change the type "nivel" variable from int (3) to Varchar (3) in MySql, and let me introduce the character, but... I preffer use the type int (the level of a character ever is a integer, obviusly).</p>
<p>Anyone know why MySql give me this error? What can I do to solve this? </p>
<p>Thanks for help!</p>

How to show validation message below each textbox using jQuery?
|
<p>I am trying to make a login form in which I have email address and password as the textbox. I have done the validation on the email address part so that it should have proper email address and also on the empty check both for email address and password text box.</p>
<p>Here is my <a href="https://jsfiddle.net/aoksoh69/5/" rel="nofollow noreferrer">jsfiddle</a>.</p>
<p>As of now, I have added an alert box saying, <code>Invalid</code> if email address and password textbox is empty. Instead of that, I would like to show a simple message just below each text box saying , please enter your email address or password if they are empty?</p>
<p>Just like it has been done here on <a href="https://www.sitepoint.com/basic-jquery-form-validation-tutorial/" rel="nofollow noreferrer">sitepoint blog</a>.</p>
<p>Is this possible to do in my current HTML form?</p>
<p><strong>Update:-</strong></p>
<pre><code><body>
<div id="login">
<h2>
<span class="fontawesome-lock"></span>Sign In
</h2>
<form action="login" method="POST">
<fieldset>
<p>
<label for="email">E-mail address</label>
</p>
<p>
<input type="email" id="email" name="email">
</p>
<p>
<label for="password">Password</label>
</p>
<p>
<input type="password" name="password" id="password">
</p>
<p>
<input type="submit" value="Sign In">
</p>
</fieldset>
</form>
</div>
<!-- end login -->
</body>
</code></pre>
<p>And my JS -</p>
<pre><code><script>
$(document).ready(function() {
$('form').on('submit', function (e) {
e.preventDefault();
if (!$('#email').val()) {
if ($("#email").parent().next(".validation").length == 0) // only add if not added
{
$("#email").parent().after("<div class='validation' style='color:red;margin-bottom: 20px;'>Please enter email address</div>");
}
} else {
$("#email").parent().next(".validation").remove(); // remove it
}
if (!$('#password').val()) {
if ($("#password").parent().next(".validation").length == 0) // only add if not added
{
$("#password").parent().after("<div class='validation' style='color:red;margin-bottom: 20px;'>Please enter password</div>");
}
} else {
$("#password").parent().next(".validation").remove(); // remove it
}
});
});
</script>
</code></pre>
<p>I am working with JSP and Servlets so as soon as I click Sign In button, it was taking me to another page with valid email and password earlier but now nothing is happening after I click Sign In button with valid email and password.</p>
<p>Any thoughts what could be wrong?</p>

Generic Linked List of Objects (Java)
|
<p>I'm pretty new to Java, with this being my second class (in College) using it. Towards the beginning of the semester, I made a simple class representing Zombies that holds their age, type, and name. Later on, I made a linked list of integers. Now, I need to make a generic linked list that can hold these 'Zombies'. I also have to make a menu that allows me to add, remove, count, and display 'Zombies'. I've been staring at this for hours, going through my book, and looking online for the answer to my problem. I can add and display these 'Zombies', but counting them in the list and trying to remove them simply has it tell me there's none with the parameters I entered. In other words, there might be a problem with how I compare the 'Zombies'. Here's my code. I understand it's a good 300 lines of code to look through... but i'm out of ideas.</p>
<p>Zombie.java</p>
<pre><code>public class Zombie
{
private String zAge;
private String zType;
private String zName;
public Zombie(String zA, String zT, String zN)
{
zAge = zA;
zType = zT;
zName = zN;
}
public void setZAge(String zA)
{
zAge = zA;
}
public void setZType(String zT)
{
zType = zT;

{
zName = zN;

ErrorHandling in Spring Security for @PreAuthorize AccessDeniedException returns 500 rather then 401
|
<p>Dear all I like to customize the error handling in a Spring 4 Rest application so it should return a HTTP Code 401 rather a Server Error 500 in case the check in @PreAuthorize annotation in my controller fails.</p>
<p>I have an own AuthenticationEntryPoint and AuthenticationFailureHandler registered which its commence / error handling methods returns a 401. This works fine for my JWT authentication but in case of a failed @PreAuthorize check with "AccessDeniedException" these error methods get never called and spring returns a server error 500. </p>
<p>How can I customize that? Looks like I missed something? Thanks for any hints in advance.</p>
<p>Here my AuthenticationEntryPoint class:</p>
<pre><code>@Component
public class RestAuthenticationEntryPoint implements AuthenticationEntryPoint {
@Override
public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException ) throws IOException, ServletException {
response.setContentType("application/json");
response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
response.getOutputStream().println("{ \"error\": \"" + authException.getMessage() + "\" }");
}
}
</code></pre>
<p>Here my AuthenticationFailureHandler:</p>
<pre><code>public class JWTAuthenticationFailureHandler implements AuthenticationFailureHandler {
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
response.sendError(401, (new StringBuilder()).append("Authentication Failed: ").append(exception.getMessage()).toString());
}
}
</code></pre>
<p>Here my spring security configuration</p>
<pre><code><security:global-method-security pre-post-annotations="enabled"/>
<security:http pattern="/api/**" entry-point-ref="restAuthenticationEntryPoint" >

NIO load file in an unit test from src/test/resources
|
<p><strong>The Problem</strong></p>
<p>I'd like to write a data import in java with java7s NIO. The user enters the path of a file as a String and the programm try to open it by using Paths. When it want to read its DosFileAttributes an java.nio.file.NoSuchFileException: file.txt occures.</p>
<p><strong>What i've found</strong></p>
<p>The only answers i've found till yet is to use an resource Stream - but this seams not practicable, because the file to be loaded is provided by the user and should not be part of the jar. Or did i missunderstood it? <a href="http://docs.oracle.com/javase/7/docs/api/java/lang/Class.html#getResourceAsStream%28java.lang.String%29" rel="noreferrer">http://docs.oracle.com/javase/7/docs/api/java/lang/Class.html#getResourceAsStream%28java.lang.String%29</a></p>
<p><strong>What i've got</strong></p>
<p>The Setup:</p>
<ul>
<li>Maven 3</li>
<li>Java7</li>
<li>TestNG</li>
<li>Spring</li>
</ul>
<p>Project Structure:</p>
<ul>
<li>src/main/java - the classes</li>
<li>src/test/java - the testcases</li>
<li>src/test/resources - perhaps file.txt ? actual it is there</li>
</ul>
<p>The source that loads the file:</p>
<pre><code>import java.io.BufferedReader;
import java.io.IOException;
import java.nio.charset.Charset;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.attribute.DosFileAttributes;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Component;
@Component( "fileLoader" )
public class BufferdFileLoader
implements FileLoader {
@Override
public List<String> loadFile( String path )
throws IOException {
if ( path == null || path.length() == 0 ) {
throw new IllegalArgumentException( "path should not be null" );
}
Path file = Paths.get( path );
// here the Exception is thrown
DosFileAttributes attrs = Files.readAttributes( file, DosFileAttributes.class );
if ( !attrs.isRegularFile() ) {
throw new IOException( "could not read file, invalid path" );
}
List<String> result = new ArrayList<String>();
try (BufferedReader reader = Files.newBufferedReader( file, Charset.forName( "UTF-8" ) )) {
String line = null;
while ( ( line = reader.readLine() ) != null ) {
result.add( line );
}
}
return result;
}
}
</code></pre>
<p>And the Test case is as simple:</p>
<pre><code>import java.io.IOException;
import java.util.List;
import javax.inject.Inject;
import lombok.Setter;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;
import org.testng.Assert;
import org.testng.annotations.Test;
/**
* Class under test {@link BufferdFileLoader}
*
*/
@ContextConfiguration
public class BufferdFileLoaderTest
extends AbstractTestNGSpringContextTests {
/**
* Class under test
*/
@Inject
@Setter
private BufferdFileLoader bufferdFileLoader;
/**
* Method under test {@link BufferdFileLoader#loadFile(String)}
*
* @throws IOException
*/
@Test( groups = { "integration" }, enabled = true )
public void testImportFeedsFromXMLFileWitEmptyXml()
throws IOException {
String filename = "empty-example-takeout.xml";
List<String> list = this.bufferdFileLoader.loadFile( filename );
Assert.assertEquals( list.size(), 0 );
}
}
</code></pre>
<p><strong>So my question is</strong></p>
<p>How to load a file using NIO so it is testable with maven and also works in production environment?</p>

Array merge on multidimensional array
|
<p>Either I'm blind or I can't find this problem anywhere here on SO.
Yesterday I had a problem with merging arrays, which I could fix with the help of SO. Today I have, again, a problem with merging arrays, but this time it's with multidimensional Arrays.</p>
<p>I have an array <code>$usergroup['groups']</code> and an array <code>$usergroup['lang']</code></p>
<p><code>$usergroup['groups']</code> looks like this:</p>
<pre><code>Array
(
[0] => Usergroup_Model Object
(
[id] => 1
[deleted] => 0
)
[1] => Usergroup_Model Object
(
[id] => 2
[deleted] => 0
)
[2] => Usergroup_Model Object
(
[id] => 3
[deleted] => 0
)
)
</code></pre>
<p>And <code>$usergroup['lang']</code> looks like this:</p>
<pre><code>Array
(
[0] => Usergroup_Model Object
(
[id] =>
[id_usergroup] => 1
[name] => Administratoren
[id_lang] => 1
)
[1] => Usergroup_Model Object
(
[id] =>
[id_usergroup] => 2
[name] => Benutzer
[id_lang] => 1
)
[2] => Usergroup_Model Object
(
[id] =>
[id_usergroup] => 3
[name] => Gäste
[id_lang] => 1
)
)
</code></pre>
<p>I want my merged array to look like this:</p>
<pre><code>Array
(
[0] => Usergroup_Model Object
(
[id] => 1
[id_usergroup] => 1
[name] => Administratoren
[id_lang] => 1
[deleted] => 0
)
[1] => Usergroup_Model Object
(
[id] => 2
[id_usergroup] => 2
[name] => Benutzer
[id_lang] => 1
[deleted] => 0
)
[2] => Usergroup_Model Object
(
[id] => 3
[id_usergroup] => 3
[name] => Gäste
[id_lang] => 1
[deleted] => 0
)
)
</code></pre>
<p><a href="http://www.whathaveyoutried.com" rel="nofollow">What have I tried?</a></p>
<p>I've tried several merging functions (<code>array_merge()</code> and <code>array_merge_recursive()</code>) of PHP, the closest result I got was, that the second Array (<code>['lang']</code>) overwrote the first Array (<code>['groups']</code>). To fix that, I tried to remove the empty values on the <code>lang</code> Array (which is always <code>id</code>). But that does not fix it. The code - at the moment - looks like this:</p>
<pre><code>public static function getAll()
{
$usergroup['groups'] = self::find();
$usergroup['lang'] = self::findInTable(array(
'id_lang' => Language_Model::getDefaultLanguage()
), self::dbTranslationTable);
foreach ($usergroup as $ug) {
$ug = array_filter($ug, function($val) {
return $val != '';
});
}
return array_merge($ug);
}
</code></pre>
<p>The array_merge() on the return command doesn't seem to do anything at all, so I'm probably not gathering the data correctly or I mess something up with the Arrays (forgetting to add [], or I don't know...). I kinda miss the forest for the trees here.</p>
<p>Any suggestions in which direction I could go?</p>
<p><strong>Edit:</strong> With the code provided by Pé de Leão I was able to solve the problem. My function now looks like this:</p>
<pre><code>public static function getAll()
{
$usergroup['groups'] = self::find();
$usergroup['lang'] = self::findInTable(array(
'id_lang' => Language_Model::getDefaultLanguage()
), self::dbTranslationTable);
$out = array();
foreach ($usergroup['groups'] as $key => $value) {
$out[] = (object) array_merge((array) $usergroup['lang'][$key], (array) $value);
}
return $out;
}
</code></pre>
<p>And the result is exactly how I wanted it!</p>

Where to put default-servlet-handler in Spring MVC configuration
|
<p>In my <code>web.xml</code>, the default servlet mapping, i.e. <code>/</code>, is mapped to Spring dispatcher. In my Spring dispatcher configuration, I have <code>DefaultAnnotationHandlerMapping</code>, <code>ControllerClassNameHandlerMapping</code> and <code>AnnotationMethodHandlerAdapter</code> which allows me to map url to controllers either by its class name or its <code>@Requestmapping</code> annotation. However, there are some static resources under the web root which I also want spring dispatcher to serve using default servlet. According to <a href="http://static.springsource.org/spring/docs/3.0.5.RELEASE/spring-framework-reference/htmlsingle/spring-framework-reference.html#mvc-default-servlet-handler" rel="noreferrer">Spring documentation</a>, this can be done using <code><mvc:default-servlet-handler/></code> tag.</p>
<p>In the configuration below, there are 4 candidate locations that I marked which are possible to insert this tag. Inserting the tag in different location causes the dispatcher to behave differently as following :</p>
<p><strong>Case 1</strong> : If I insert it at location 1, the dispatcher will no longer be able to handle mapping by the @RequestMapping and controller class name but it will be serving the static content normally.</p>
<p><strong>Cas 2, 3</strong> : It will be able to handle mapping by the @RequestMapping and controller class name as well as serving the static content if other mapping cannot be done successfully.</p>
<p><del><strong>Case 4</strong> : It will not be able to serve the static contents.</del> <em>Removal Note : This was a bug when implementing a controller which has a method mapped to <code>/**</code> but does not have explicit request mapping on the controller class name.</em></p>
<p>Therefore, <strong>Case 2</strong> and <strong>3</strong> are desirable .According to Spring documentation, this tag configures a handler which precedence order is given to lowest so why the position matters? and Which is the best position to put this tag?</p>

Unable to use webpack dynamic import because of static publicPath
|
<p>I love the ability to dynamically import a chunk using the <code>import</code> command in webpack 3. Unfortunately it seems as if it can only be used if the resources are in a rather static directory configuration on the server.</p>
<p>In my environment the html pages generated dynamically in the backend (let's say <code>http:/localhost/app</code>). All other resources (js, css, images, etc.) are in a different directory (let's say <code>http:/localhost/res</code>) but additionally <code>res</code> is not static but can rather change dynamically in the backend.</p>
<p>As long as I do not use any dynamic imports everything works as expected but when trying to dynamically load any chunks this fails because webpack by default expects the chunks to be in <code>http:/localhost/app</code> and I cannot use <code>publicPath</code> because the url where the resources are is dynamic.</p>
<p>Is there any way to (runtime) configure webpack into loading the resources relative to the path where the current resource is located.
If for example the chunk <code>page1.js</code> located in <code>http:/localhost/resA</code> dynamically loads the chunk <code>sub1.js</code> he should look for it in <code>http:/localhost/resA</code> instead of <code>http:/localhost/app</code>.</p>
<p><strong>generated html will be available at <code>http:/localhost/app/page1</code>:</strong></p>
<pre><code><!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<script src="http:/localhost/resA/page1.bundle.js"></script>
</body>
</html>
</code></pre>
<p><strong>file <code>src/page1.js</code> will be available as <code>http:/localhost/resA/page1.bundle.js</code>:</strong></p>
<pre><code>import(/* webpackChunkName: "sub1" */ './sub1').then(({MyClass}) => {/*...*/});
</code></pre>
<p><strong>file <code>src/sub1</code> will be available as <code>http:/localhost/resA/sub1.bundle.js</code>:</strong></p>
<pre><code>export class MyClass {};
</code></pre>
<p><strong>file `webpack.config.js':</strong></p>

How to filter and map array of documents in MongoDB query?
|
<p>So I've got these documents in my people collection:</p>
<pre><code>{
"_id" : ObjectId("595c0630939a8ae59053a9c3"),
"name" : "John Smith",
"age" : 37,
"location" : "San Francisco, CA",
"hobbies" : [
{
"name" : "Cooking",
"type" : "Indoor",
"regular" : true
},
{
"name" : "Baseball",
"type" : "Outdoor",
"regular" : false
}
]
}
{
"_id" : ObjectId("595c06b7939a8ae59053a9c4"),
"name" : "Miranda Thompson",
"age" : 26,
"location" : "Modesto, CA",
"hobbies" : [
{
"name" : "Lego building",
"type" : "Indoor",
"regular" : false
},
{
"name" : "Yoga",
"type" : "Indoor",
"regular" : false
}
]
}
{
"_id" : ObjectId("595c078e939a8ae59053a9c5"),
"name" : "Shelly Simon",
"age" : 26,
"location" : "Salt Lake City, UT",
"hobbies" : [
{
"name" : "Hunting",
"type" : "Outdoor",
"regular" : false
},
{
"name" : "Soccer",
"type" : "Outdoor",
"regular" : true
}
]
}
</code></pre>
<p>I am trying to filter my "hobbies" array only to regular hobbies AND project the fields _id, name, age and hobby's name and type.</p>
<p>I want my output to be something like this:</p>
<pre><code>{
"_id" : ObjectId("595c0630939a8ae59053a9c3"),
"name" : "John Smith",
"age" : 37,
"hobbies" : [
{
"name" : "Cooking",
"type" : "Indoor"
}
]
}
{
"_id" : ObjectId("595c06b7939a8ae59053a9c4"),
"name" : "Miranda Thompson",
"age" : 26,
"hobbies" : []
}
{
"_id" : ObjectId("595c078e939a8ae59053a9c5"),
"name" : "Shelly Simon",
"age" : 26,
"hobbies" : [
{
"name" : "Soccer",
"type" : "Outdoor"
}
]
}
</code></pre>
<p>Well... I can achieve this output using this command in mongo shell:</p>
<pre><code>db.people.aggregate([
{
$project: {
hobbies: {
$filter: {
input: "$hobbies",
as: "hobby",
cond: { $eq: ["$$hobby.regular", true] }
}
},
name: 1,
age: 1
}
},
{
$project: {
"hobbies.name": 1,
"hobbies.type": 1,
name: 1,
age: 1
}
}
])
</code></pre>
<p>As you can see, I had to use two $project operators in sequence and I think this smells bad.</p>
<p>Is there a way to achieve the same result with another query that does not use the same operator twice and in sequence?</p>

.NET Core RuntimeIdentifier vs TargetFramework
|
<p>Can someone explain the purpose of this two in csproj file (VS2017):</p>
<pre><code><TargetFramework>netstandard1.6</TargetFramework>
<RuntimeIdentifier>win7</RuntimeIdentifier>
</code></pre>
<p>I just migrated from VS2015 and now can't publish my web api because it looks I should use only one target framework. In addition I can't specify multiple RIDs.
All these changed things make me frustrated. Nothing works from scratch, should overcome something over and over. </p>
<p>I just want developing my web-api on windows, run xUnit tests here and then deploy web-api to run on linux (ubuntu) server.
What I should put in both parameters in csproj ?
Links with good explanation is highly appreciated. </p>
<p><strong>Update1</strong></p>
<p>I have web api with referenced .net core libraries. Everything where migrated from VS2015. Now in root project I have
<code><TargetFrameworks>netcoreapp1.1;net461</TargetFrameworks></code>. When I publish via VS2017 I got error: </p>
<blockquote>
<p>C:\Program
Files\dotnet\sdk\1.0.3\Sdks\Microsoft.NET.Sdk\buildCrossTargeting\Microsoft.NET.Sdk.targets(31,5):
error : The 'Publish' target is not supported without specifying a
target framework. The current project targets multiple frameworks,
please specify the framework for the published application.</p>
</blockquote>
<p>But I have specified target framework in publish as <code>netcoreapp1.1</code>.
OK. Then I updated my csproj with <code><PropertyGroup Condition="$(TargetFramework)'=='netcoreapp1.1'">
<RuntimeIdentifier>ubuntu.16.10-x64</RuntimeIdentifier>
</PropertyGroup></code> as suggested below.
But now I even can't build app, get error:</p>
<blockquote>
<p>5>C:\Program Files (x86)\Microsoft Visual
Studio\2017\Enterprise\MSBuild\Sdks\Microsoft.NET.Sdk\build\Microsoft.NET.Sdk.targets(92,5):

you have restored this project for TargetFramework='netcoreapp1.1' and
RuntimeIdentifier='ubuntu.16.10-x64'.</p>
</blockquote>
<p>I just want develop with VS2017 at windows 8.1/windows7 and deploy to ubuntu 16.10.
What I'm doing wrong ?</p>
<p><strong>Update2</strong></p>
<p>I have 8 projects in solution. 3 of them are xUnit tests. Thus we have 5 projects. 4 of these 5 are class libraries and 1 is my web-app.
All 4 class libraries have this: </p>
<pre><code><TargetFrameworks>netstandard1.6;net461</TargetFrameworks>
<ItemGroup Condition=" '$(TargetFramework)' == 'net461' ">
<Reference Include="System" />
<Reference Include="Microsoft.CSharp" />
</ItemGroup>
</code></pre>
<p>My web app:</p>

STM32F429 is not receiving the CAN Message
|
<p>I am using STM32F429 Microcontroller and need to implement CAN Bus Communication between CAN2 and PCAN View.I am able to transmit the message from CAN2 but I am not able to receive any message.I am using TJA1041A CAN transreceiver in the microcontroller.The Problem is that during debugging my CAN bus are properly initalized but it doesn't go to the receive command although I have initalized FIFO0.Herewith I am attching the program for further reference.I have used STM32 HAL Cube for programming.</p>

$httpBackend in AngularJs Jasmine unit test
|
<p>I'm unable to get my unit test to work properly. I have a $scope array that starts out empty, but should be filled with an $http.get(). In the real environment, there'd be approx 15 or so objects in the array, but for my unit test I just grabbed 2. For the unit test, I have:</p>
<pre><code>expect($scope.stuff.length).toBe(2);
</code></pre>
<p>But jasmine's error is: Expected 0 to be 2.</p>
<p>here's my controller.js:</p>
<pre><code>$scope.stuff = [];
$scope.getStuff = function () {
var url = site.root + 'api/stuff';
$http.get(url)
.success(function (data) {
$scope.stuff = data;
})
.error(function(error) {
console.log(error);
});
};
</code></pre>
<p>and my controller.spec.js is:</p>
<pre><code>/// <reference path="../../../scripts/angular-loader.min.js" />
/// <reference path="../../../scripts/angular.min.js" />
/// <reference path="../../../scripts/angular-mocks.js" />
/// <reference path="../../../scripts/angular-resource.js" />
/// <reference path="../../../scripts/controller.js" />
beforeEach(module('ui.router'));
beforeEach(module('ngResource'));
beforeEach(module('ngMockE2E'));
beforeEach(module('myApplication'));
var $scope;
var controller;
var httpLocalBackend;
beforeEach(inject(function ($rootScope, $controller, $injector) {
$scope = $rootScope.$new();
controller = $controller("StuffController", {
$scope: $scope
});
}));
beforeEach(inject(function ($httpBackend) {
httpLocalBackend = $httpBackend;
}));
it('should get stuff', function () {
var url = '/api/stuff';
var httpResponse = [{ "stuffId": 1 }, { "stuffId": 2 }];
httpLocalBackend.expectGET(url).respond(200, httpResponse);
$scope.getStuff();
expect($scope.stuff.length).toBe(2);
//httpLocalBackend.flush();
} );
</code></pre>
<p>Now, obviously, I changed variable names and such since this is for work, but hopefully this is enough information for anybody to help me. I can provide more if needed. I also get a second error when uncommenting the .flush() line, but I'll get to that a bit later.</p>
<p>Any help is greatly appreciated and thanks in advance!</p>
<p>EDIT:</p>
<p>Finally got it working! Here's my final code:</p>
<pre><code>it('should get stuff', function () {
var url = '/api/stuff';
var httpResponse = [{ "stuffId": 1 }, { "stuffId": 2 }];
httpLocalBackend.expectGET(url).respond(200, httpResponse);
$scope.getStuff();
httpLocalBackend.flush();
expect($scope.stuff.length).toBe(2);
} );
</code></pre>
<p>EDIT 2:
I ran into another problem, which I think may have been the root cause of this. See <a href="https://stackoverflow.com/questions/25794501/unit-test-failing-when-function-called-on-startup">Unit test failing when function called on startup</a></p>

Can I use ng-model with isolated scope?
|
<p>I am creating simple ui-datetime directive. It splits javascript Date object into _date, _hours and _minutes parts. _date uses jquery ui datepicker, _hours and _minutes - number inputs.</p>
<pre><code>angular.module("ExperimentsModule", [])
.directive("uiDatetime", function () {
return {
restrict: 'EA',
replace: true,
template: '<div class="ui-datetime">' +
'<input type="text" ng-model="_date" class="date">' +
'<input type="number" ng-model="_hours" min="0" max="23" class="hours">' +
'<input type="number" ng-model="_minutes" min="0" max="59" class="minutes">' +
'<br />Child datetime1: {{datetime1}}' +
'</div>',
require: 'ngModel',
scope: true,
link: function (scope, element, attrs, ngModelCtrl) {
var elDate = element.find('input.date');
ngModelCtrl.$render = function () {
var date = new Date(ngModelCtrl.$viewValue);
var fillNull = function (num) {
if (num < 10) return '0' + num;
return num;
};
scope._date = fillNull(date.getDate()) + '.' + fillNull(date.getMonth() + 1) + '.' + date.getFullYear();
scope._hours = date.getHours();
scope._minutes = date.getMinutes();
};
elDate.datepicker({
dateFormat: 'dd.mm.yy',
onSelect: function (value, picker) {
scope._date = value;
scope.$apply();
}
});
var watchExpr = function () {
var res = scope.$eval('_date').split('.');
if (res.length == 3) return new Date(res[2], res[1] - 1, res[0], scope.$eval('_hours'), scope.$eval('_minutes'));
return 0;
};
scope.$watch(watchExpr, function (newValue) {
ngModelCtrl.$setViewValue(newValue);
}, true);
}
};
});
function TestController($scope) {
$scope.datetime1 = new Date();
}

<p><a href="http://jsfiddle.net/andreev_artem/nWsZp/3/"><kbd>jsfiddle</kbd></a></p>
<p>On github: <a href="https://github.com/andreev-artem/angular_experiments/tree/master/ui-datetime">https://github.com/andreev-artem/angular_experiments/tree/master/ui-datetime</a></p>
<p>As far as I understand - best practice when you create a new component is to use isolated scope.</p>
<p>When I tried to use isolated scope - nothing works. ngModel.$viewValue === undefined.</p>
<p>When I tried to use new scope (my example, not so good variant imho) - ngModel uses value on newly created scope.</p>
<p>Of course I can create directive with isolated scope and work with ngModel value through "=expression" (<a href="https://github.com/andreev-artem/angular_experiments/blob/uiDatetime_impl2/ui-datetime/ui-datetime.js">example</a>). But I think that working with ngModelController is a better practice.</p>
<p>My questions:</p>
<ol>
<li>Can I use ngModelController with isolated scope?</li>
<li>If it is not possible which solution is better for creating such component?</li>
</ol>

In python, how can I print lines that do NOT contain a certain string, rather than print lines which DO contain a certain string:
|
<p>I am trying to condense a very large log file, and to do so, I must eliminate every line which contains the string "StatusRequest" and "StatusResponse", while printing the other lines w/o this string. The code I have so far is as follows (to run from the command prompt):</p>
<blockquote>
<pre><code> if (sys.argv[1])=="--help":
print ("\n")
print ("Argument 1: Enter name of '.py' file")
print ("-i or --input: name of Catalina log")
print ("-o or --output: file to output to")
print ("\n")
if (sys.argv[1])=="-h":
print ("\n")
print ("Argument 1: Enter name of '.py' file")
print ("-i or --input: name of Catalina log")
print ("-o or --output: file to output to")
print ("\n")
else:
print 'Number of arguments:', len(sys.argv), 'arguments.'
print 'Argument List:', str(sys.argv)
Numarg = (len(sys.argv))
i=1
while i<=(Numarg-4):
search1="StatusRequest"
search2="StatusResponse"
if (sys.argv[Numarg-2])=="-o":
outputfile=sys.argv[Numarg-1]
if (sys.argv[Numarg-2])=="--output":
outputfile=sys.argv[Numarg-1]
if (sys.argv[i])=="-i":
filename=(sys.argv[i+1])
log=(filename)
print ("You entered the log: " + log)
f=open(log, 'r')
read_data = f.read()
f.close
f=open(log, 'r')
readlines_data=f.readlines()
f.close()
i=i+1
if (sys.argv[i])=="--input":
filename=(sys.argv[i+1])
log=(filename)
print ("You entered the log: " + log)
f=open(log, 'r')
read_data = f.read()
f.close
f=open(log, 'r')
readlines_data=f.readlines()
f.close()
i=i+1
for line in readlines_data:
if not ("StatusRequest" or "StatusResponse") in line:
result=line
print (line)
f=open(outputfile, 'a')
f.write(result + "\n")
f.close()
</code></pre>
</blockquote>
<p>You can just focus on the end of the script to answer my question, really...Anyways, I am not sure why this doesn't work...It is outputting every line still. And I already tried switching the place of the not so it would make more sense idiomatically, but it didn't change anything with the code. Any help is much appreciated :)</p>

Android Camera Server Died and Camera Error - 100

How to create a oAuth request using java?
|
<p>I need to make a connection with <a href="http://developer.viagogo.net/documentation/api-security/oauth-authentication-for-public-services">Viagogo website</a> using oAuth. Referring to their <a href="http://developer.viagogo.net/documentation/api-security/oauth-authentication-for-public-services">documentation</a> I need to create a request similar to the following one </p>
<pre><code>Using the example in step 1A, this means you may generate a signature base string that looks like the following:
GET&http%3A%2F%2Fapi.viagogo.net%2FPublic%2FSimpleOAuthAccessRequest&oauth_consumer_key%3Dtestkey%26oauth_nonce%3Dmyn0nc3%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1292404912%26oauth_version%3D1.0%26scope%3DAPI.Public

Reading in environmental Variable Using Viper Go
|
<p>I am trying to make Viper read my environment variables, but its not working. Here is my configuration:</p>
<pre><code># app.yaml
dsn: RESTFUL_APP_DSN
jwt_verification_key: RESTFUL_APP_JWT_VERIFICATION_KEY
jwt_signing_key: RESTFUL_APP_JWT_SIGNING_KEY
jwt_signing_method: "HS256"
</code></pre>
<p>And my <code>config.go</code> file:</p>
<pre><code>package config
import (
"fmt"
"strings"
"github.com/go-ozzo/ozzo-validation"
"github.com/spf13/viper"
)
// Config stores the application-wide configurations
var Config appConfig
type appConfig struct {
// the path to the error message file. Defaults to "config/errors.yaml"
ErrorFile string `mapstructure:"error_file"`
// the server port. Defaults to 8080
ServerPort int `mapstructure:"server_port"`
// the data source name (DSN) for connecting to the database. required.
DSN string `mapstructure:"dsn"`
// the signing method for JWT. Defaults to "HS256"
JWTSigningMethod string `mapstructure:"jwt_signing_method"`
// JWT signing key. required.
JWTSigningKey string `mapstructure:"jwt_signing_key"`
// JWT verification key. required.
JWTVerificationKey string `mapstructure:"jwt_verification_key"`
}
func (config appConfig) Validate() error {
return validation.ValidateStruct(&config,
validation.Field(&config.DSN, validation.Required),
validation.Field(&config.JWTSigningKey, validation.Required),
validation.Field(&config.JWTVerificationKey, validation.Required),
)
}
func LoadConfig(configpaths ...string) error {
v := viper.New()
v.SetConfigName("app")
v.SetConfigType("yaml")
v.SetEnvPrefix("restful")
v.AutomaticEnv()
v.SetDefault("error_file", "config/errors.yaml")
v.SetDefault("server_port", 1530)
v.SetDefault("jwt_signing_method", "HS256")
v.SetEnvKeyReplacer(strings.NewReplacer(".", "_"))
for _, path := range configpaths {
v.AddConfigPath(path)
}
if err := v.ReadInConfig(); err != nil {
return fmt.Errorf("Failed to read the configuration file: %s", err)
}
if err := v.Unmarshal(&Config); err != nil {
return err
}
// Checking with this line. This is what I get:
// RESTFUL_JWT_SIGNING_KEY
fmt.Println("Sign Key: ", v.GetString("jwt_signing_key"))
return Config.Validate()
}
</code></pre>
<p>This line <code>fmt.Println("Sign Key: ", v.GetString("jwt_signing_key"))</code> gives me just the key passed in the yaml file <code>RESTFUL_JWT_SIGNING_KEY</code>. I don't know what I'm doing wrong.</p>
<p>According to doc:</p>
<blockquote>
<p>AutomaticEnv is a powerful helper especially when combined with
SetEnvPrefix. When called, Viper will check for an environment
variable any time a viper.Get request is made. It will apply the
following rules. It will check for a environment variable with a name
matching the key uppercased and prefixed with the EnvPrefix if set.</p>
</blockquote>
<p>So, why isn't it reading the environment variables?</p>
<p>Using <code>JSON</code></p>
<pre><code>{
"dsn": "RESTFUL_APP_DSN",
"jwt_verification_key": "RESTFUL_APP_JWT_VERIFICATION_KEY",
"jwt_signing_key": "RESTFUL_APP_JWT_SIGNING_KEY",
"jwt_signing_method": "HS256"
}
</code></pre>
<p>And my parser looks like thus:</p>
<pre><code>// LoadConfigEnv loads configuration from the given list of paths and populates it into the Config variable.
// Environment variables with the prefix "RESTFUL_" in their names are also read automatically.
func LoadConfigEnv(environment string, configpaths ...string) error {
v := viper.New()
v.SetConfigName(environment)
v.SetConfigType("json")
v.SetEnvPrefix("restful")
v.AutomaticEnv()
v.SetDefault("jwt_signing_method", "HS256")
v.SetDefault("error_file", "config/errors.yaml")
v.SetDefault("server_port", 1530)
v.SetEnvKeyReplacer(strings.NewReplacer(".", "_"))
for _, path := range configpaths {
v.AddConfigPath(path)
}
if err := v.ReadInConfig(); err != nil {
return fmt.Errorf("Failed to read the configuration file: %s", err)
}
if err := v.Unmarshal(&Config); err != nil {
return err
}
return Config.Validate()
}
</code></pre>
<p>In the <code>Validate</code> function, I decided to check the <code>Config</code> struct, and this is what I got:</p>
<p><code>Config: {config/errors.yaml 1530 RESTFUL_APP_DSN HS256 RESTFUL_APP_JWT_SIGNING_KEY RESTFUL_APP_JWT_VERIFICATION_KEY}</code></p>

Representing an Abstract Syntax Tree in C
|
<p>I'm implementing a compiler for a simple toy language in C. I have a working scanner and parser, and a reasonable background on the conceptual function/construction of an AST. My question is related to the specific way to represent an AST in C. I've come across three styles pretty frequently in different texts/resources online:</p>
<p><strong>One struct per type of node.</strong></p>
<p>This has a base node "class"(struct) that is the first field in all the child structs. The base node contains an enum that stores the type of node(constant, binary operator, assignment, etc). Members of the struct are accessed using a set of macros, with one set per struct. It looks something like this:</p>
<pre><code>struct ast_node_base {
enum {CONSTANT, ADD, SUB, ASSIGNMENT} class;
};
struct ast_node_constant {
struct ast_node_base *base;
int value;
};
struct ast_node_add {
struct ast_node_base *base;
struct ast_node_base *left;
struct ast_node_base *right;
};
struct ast_node_assign {

#define ASSIGN_RIGHT(node) ((ast_node_assign*)node)->right;
</code></pre>
<p><strong>One struct per layout of node.</strong></p>
<p>This appears to be mostly the same as the above layout, except instead of having ast_node_add and ast_node_assign it would have an ast_node_binary to represent both, because the layout of the two structs is the same and they only differ by the contents of base->class. The advantage to this seems to be a more uniform set of macros(LEFT(node) for all nodes with a left and right instead of one pair of macros per), but the disadvantage seems that the C type checking won't be as useful(there would be no way to detect an ast_node_assign where there should only be an ast_node_add, for example).</p>
<p><strong>One struct total, with a union to hold different types of node data.</strong></p>
<p>A better explanation of this than I can give can be found <a href="http://lambda.uta.edu/cse5317/notes/node25.html">here</a>. Using the types from the previous example it would look like:</p>
<pre><code>struct ast_node {
enum { CONSTANT, ADD, SUB, ASSIGNMENT } class;
union { int value;
struct { struct ast_node* left;
struct ast_node* right; } op;
};
</code></pre>
<p>I'm inclined to like the third option the most because it makes recursive traversal much easier(in that lots of pointer casting is avoided in favor of the union), but it also doesn't take advantage of C type checking. The first option seems the most dangerous in that it relies on pointers to structs being cast to access the member of any node(even different members of the same node requiring different cases to access(base vs. left)), but these casts are type checked so that might be moot. The second option to me seems like the worst of both worlds, although maybe I'm missing something.</p>
<p><strong>Which of these three schemes are the best, and why? Is there a better fourth option I haven't come across yet?</strong> I'm assuming none of them are a "one size fits all" solution, so if it matters the language I'm implementing is a statically typed imperative language, almost a small subset of C.</p>
<p>A specific question I have about the third(union) layout. <strong>If I use only the value field, will there be empty space following the value to accommodate for the possibility of op being written to?</strong></p>

UIView Round Corners with Shadow
|
<p>I am trying to display a UIView with round corners and with a drop shadow. But the problem is that maskToBounds property only works for either of the case. </p>
<p>If maskToBounds is YES then round corners show up and when NO then shadow shows up. Here is the implementation but it only displays round corners with no shadow: </p>
<pre><code>[self.view setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"blue_gradient.jpeg"]]];
self.view.layer.masksToBounds = YES;
self.view.layer.opaque = NO;
self.view.layer.cornerRadius = 15.0f;
self.view.layer.shadowColor = [UIColor blackColor].CGColor;
self.view.layer.shadowRadius = 5.0;
self.view.layer.shadowOffset = CGSizeMake(3.0, 3.0);
self.view.layer.shadowOpacity = 0.9f;
</code></pre>
<p>ideas!</p>
<p>NOTE: I have read and implemented the code in the following thread but it does not work:
<a href="https://stackoverflow.com/questions/4754392/uiview-with-rounded-corners-and-drop-shadow">UIView with rounded corners and drop shadow?</a></p>
<p><strong>UPDATE 1:</strong> </p>
<p>I tried to create two separate views. One will represent the radius and one will represent the shadow. The problem is that is creates the shadow on top of the radius view as shown in the screenshot below: </p>
<p><img src="https://i.stack.imgur.com/1EiIh.png" alt="enter image description here"></p>
<p>H</p>
<pre><code>ere is the code:
self.view.layer.masksToBounds = YES;
self.view.layer.opaque = NO;
self.view.layer.cornerRadius = 15.0f;
// self.view.backgroundColor = [UIColor clearColor];
self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"blue_gradient.jpeg"]];
//
UIView *shadowView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
shadowView.layer.shadowColor = [UIColor blackColor].CGColor;
shadowView.layer.shadowRadius = 2.0;
shadowView.backgroundColor = [UIColor clearColor];
shadowView.layer.shadowOffset = CGSizeMake(3.0, 3.0);
shadowView.layer.shadowOpacity = 0.9f;
shadowView.layer.shadowPath = [UIBezierPath
bezierPathWithRect:CGRectMake(0, 0, 100, 100)].CGPath;
[self.view addSubview:shadowView];
</code></pre>
<p>UPDATE 2: </p>
<p>Inverted still does not work. No round corners are created. </p>
<pre><code>UIView *roundCornerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
roundCornerView.layer.masksToBounds = YES;
roundCornerView.layer.opaque = NO;
roundCornerView.layer.cornerRadius = 15.0f;
self.view.layer.shadowColor = [UIColor blackColor].CGColor;
self.view.layer.shadowRadius = 2.0;
//self.view.backgroundColor = [UIColor clearColor];
self.view.layer.shadowOffset = CGSizeMake(3.0, 3.0);
self.view.layer.shadowOpacity = 0.9f;
self.view.layer.shadowPath = [UIBezierPath
bezierPathWithRect:CGRectMake(0, 0, 100, 100)].CGPath;
[self.view addSubview:roundCornerView];
</code></pre>
<p><strong>SOLUTION:</strong> </p>
<pre><code> UIView *roundCornerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
roundCornerView.layer.masksToBounds = YES;
roundCornerView.layer.opaque = NO;
roundCornerView.layer.cornerRadius = 15.0f;
roundCornerView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"blue_gradient.jpeg"]];
self.view.layer.shadowColor = [UIColor blackColor].CGColor;
self.view.layer.shadowRadius = 2.0;
self.view.backgroundColor = [UIColor clearColor];
self.view.layer.shadowOffset = CGSizeMake(3.0, 3.0);
self.view.layer.shadowOpacity = 0.9f;
//self.view.layer.shadowPath = [UIBezierPath
// bezierPathWithRect:CGRectMake(0, 0, 100, 100)].CGPath;
[self.view addSubview:roundCornerView];

zf2 navigation - 'Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for navigation'
|
<p>Hy everybody!</p>
<p>I am learning zf2, and trying to set up a navigation panel(based on: <a href="https://stackoverflow.com/questions/11397226/zend-framework-2-zend-navigation">Zend Framework 2: Zend_Navigation</a>), but the answer from the computer is still:</p>
<p>An error occurred
An error occurred during execution; please try again later.
Additional information:
Zend\ServiceManager\Exception\ServiceNotFoundException
File:
/var/www/zf2-tutorial/vendor/zendframework/zendframework/library/Zend/ServiceManager/ServiceManager.php:453
Message:
Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for navigation</p>
<p>The module.config.php contain:</p>
<pre><code> 'servicemanager' => array(
'factories' => array(
'navigation' => function($sm) {
$config = $sm->get('Config');
$navigation = new \Zend\Navigation\Navigation($config->get('navigation'));
return $navigation;
}
),
),
</code></pre>
<p>I have an application.global.php in the main config/autoload folder which is looks like:</p>
<pre><code><?php
return array(
// All navigation-related configuration is collected in the 'navigation' key
'navigation' => array(
// The DefaultNavigationFactory we configured in (1) uses 'default' as the sitemap key
'default' => array(

'Application' => array(
'label' => 'Alap alkalmazás',
'route' => 'application',
'action' => 'index',
)
),
),
);
</code></pre>
<p>And from the controller i give this command:</p>
<pre><code>$config = $this->getServiceLocator()->get('navigation');
</code></pre>
<p>Could somebody help me to solve this problem?
I read about <a href="http://adam.lundrigan.ca/2012/07/quick-and-dirty-zf2-zend-navigation/" rel="nofollow noreferrer">http://adam.lundrigan.ca/2012/07/quick-and-dirty-zf2-zend-navigation/</a> , I tried it, and I did it, but I would like to combine with acl so that I wrote this question.</p>
<p>Thanks for every help!</p>

OpenCV: how to use createBackgroundSubtractorMOG
|
<p>I was trying to go through this tutorial på OpenCV.org:</p>
<p><a href="http://docs.opencv.org/trunk/doc/tutorials/video/background_subtraction/background_subtraction.html#background-subtraction" rel="noreferrer">http://docs.opencv.org/trunk/doc/tutorials/video/background_subtraction/background_subtraction.html#background-subtraction</a></p>
<p>The MOG pointer is initialized as</p>
<pre><code>Ptr<BackgroundSubtractor> pMOG; //MOG Background subtractor
</code></pre>
<p>and in main, it is used in the following manner:</p>
<pre><code>pMOG = createBackgroundSubtractorMOG();
</code></pre>
<p>However, this yields the following error:</p>
<pre><code> Error: Identifier "createBackgroundSubtractorMOG" is undefined
</code></pre>
<p>Also, when the background model is to be updated, the following command is used:</p>
<pre><code>pMOG->apply(frame, fgMaskMOG);
</code></pre>
<p>Which in turn yields the following error:</p>
<pre><code> Error: class "cv::BackgroundSubtractor" has no member "apply"

<p>Any idea of what can be done about this?

rgb to yuv420 algorithm efficiency

<p>I wrote an algorithm to convert a RGB image to a YUV420. I spend a long time trying to make it faster but I haven't find any other way to boost its efficiency, so now I turn to you so you can tell me if this is as good as I get, or if there's another more efficient way to do it (the algorithm is in C++ but C and assembler are also options)</p>

How to set custom handler_name metadata for subtitle stream using FFMPEG
|
<p>I'm currently using <a href="https://www.ffmpeg.org/" rel="noreferrer">FFMPEG</a> to embed subtitles into my MP4 files and I am stumped trying to figure out how to custom set the "handler_name" metadata tag on my subtitle stream so I can control the name that is displayed when selecting the subtitle within a player like <a href="http://mpc-hc.org/" rel="noreferrer">MPC-HC</a> (Media Player Classic)?</p>
<p>My current command to embed the subtitle is:</p>
<pre><code>ffmpeg -i "video.mp4" -sub_charenc UTF-8 -i "video.srt" -c:v copy -c:a copy -c:s mov_text -metadata:s:s:0 language=eng -metadata:s:s:0 handler_name="English" -id3v2_version 3 -write_id3v1 1 "subbed_video.mp4"
</code></pre>
<p>Output:</p>
<pre><code>C:\path\to>ffmpeg -y -i "video.mp4" -sub_charenc UTF-8 -i "video.srt" -c:v copy -c:a copy -c:s mov_text -metadata:s:s:0 language="eng" -metadata:s:s:0 handler_name="English" -id3v2_version 3 -write_id3v1 1 "subbed_video.mp4"

</code></pre>
<p>No matter what options I have tried or what order I place the -metadata tags in, this tag simply will not set with <a href="https://www.ffmpeg.org/" rel="noreferrer">FFMPEG</a>? I find it really ugly to see <strong>SubtitleHandler [eng] (tx3g) (English)</strong> within my player's menu instead of simply saying <strong>English</strong>.</p>
<p>Now, I can work around this issue by using <a href="http://gpac.wp.mines-telecom.fr/mp4box/" rel="noreferrer">MP4BOX</a> to embed the subtitles into my mp4's using:</p>
<pre><code>MP4BOX -lang eng -add "video.srt:name=English" "video.mp4" -out "subbed_video.mp4"
</code></pre>
<p>Adding <strong>"name=English"</strong> allows me to set the subtitle stream's "handler_name" to "English"; which displays perfectly in <a href="https://www.ffmpeg.org/" rel="noreferrer">FFMPEG</a> and <a href="http://mpc-hc.org/" rel="noreferrer">MPC-HC</a>, but the problem is that I do not want my app to be dependent on an additional external tool like <a href="http://gpac.wp.mines-telecom.fr/mp4box/" rel="noreferrer">MP4BOX</a> if it can be avoided?</p>
<p>I would greatly appreciate any advice regarding how to properly set the "handler_name" tag on my subtitle stream using <a href="https://www.ffmpeg.org/" rel="noreferrer">FFMPEG</a>, or maybe a confirmation as to whether <a href="https://www.ffmpeg.org/" rel="noreferrer">FFMPEG</a> can even handle this tag seeing as it is not technically listed in <a href="https://www.ffmpeg.org/doxygen/2.4/group__metadata__api.html" rel="noreferrer">FFMPEG's valid metadata tag list</a>?</p>
<p><em>P.S. As an alternative to <a href="https://www.ffmpeg.org/" rel="noreferrer">FFMPEG</a>, I would be willing to use <a href="http://atomicparsley.sourceforge.net/" rel="noreferrer">AtomicParsley</a> to set the "handler_name" as I will already be using it to set advanced metadata on the "subbed_video.mp4" after I embed the subtitles. It does seem like it would be possible to do with <a href="http://atomicparsley.sourceforge.net/" rel="noreferrer">AtomicParsley</a>, but I have not been able to understand half the help information with regards to setting custom ATOM's.</em></p>
<p>TIA!!</p>

Cancel async_read due to timeout
|
<p>I'm trying to write a wrapper synchronous method around <code>async_read</code> to allow non blocking reads on a socket. Following several examples around internet I have developed a solution that seems to be almost right but which is not working.</p>
<p>The class declares these relevant attributes and methods:</p>
<pre><code>class communications_client
{
protected:
boost::shared_ptr<boost::asio::io_service> _io_service;
boost::shared_ptr<boost::asio::ip::tcp::socket> _socket;
boost::array<boost::uint8_t, 128> _data;
boost::mutex _mutex;
bool _timeout_triggered;
bool _message_received;
boost::system::error_code _error;
size_t _bytes_transferred;
void handle_read(const boost::system::error_code & error, size_t bytes_transferred);
void handle_timeout(const boost::system::error_code & error);
size_t async_read_helper(unsigned short bytes_to_transfer, const boost::posix_time::time_duration & timeout, boost::system::error_code & error);
...
}
</code></pre>
<p>The method <code>async_read_helper</code> is the one that encapsulates all the complexity, while the other two <code>handle_read</code>and <code>handle_timeout</code> are just the event handlers. Here is the implementation of the three methods:</p>
<pre><code>void communications_client::handle_timeout(const boost::system::error_code & error)
{
if (!error)
{
_mutex.lock();
_timeout_triggered = true;
_error.assign(boost::system::errc::timed_out, boost::system::system_category());
_mutex.unlock();
}
}
void communications_client::handle_read(const boost::system::error_code & error, size_t bytes_transferred)
{
_mutex.lock();
_message_received = true;
_error = error;
_bytes_transferred = bytes_transferred;
_mutex.unlock();
}
size_t communications_client::async_read_helper(unsigned short bytes_to_transfer, const boost::posix_time::time_duration & timeout, boost::system::error_code & error)
{
_timeout_triggered = false;
_message_received = false;
boost::asio::deadline_timer timer(*_io_service);
timer.expires_from_now(timeout);
timer.async_wait(
boost::bind(
&communications_client::handle_timeout,
this,
boost::asio::placeholders::error));
boost::asio::async_read(
*_socket,
boost::asio::buffer(_data, 128),
boost::asio::transfer_exactly(bytes_to_transfer),
boost::bind(
&communications_client::handle_read,
this,
boost::asio::placeholders::error,
boost::asio::placeholders::bytes_transferred));
while (true)
{
_io_service->poll_one();
if (_message_received)
{
timer.cancel();
break;
}
else if (_timeout_triggered)
{
_socket->cancel();
break;
}
}
return _bytes_transferred;
}
</code></pre>
<p>The main question I have is: why this works with a loop on <code>_io_service->poll_one()</code>and no without a loop and calling <code>_io_service->run_one()</code>? Also, I would like to know if it looks correct to anyone who is more used to work with Boost and Asio. Thank you!</p>
<hr>
<h2><strong>FIX PROPOSAL #1</strong></h2>
<p>According to the comments done by <a href="https://stackoverflow.com/users/981959/jonathan-wakely">Jonathan Wakely</a> the loop could be replaced using <code>_io_service->run_one()</code> with a call to <a href="http://www.boost.org/doc/libs/1_49_0/doc/html/boost_asio/reference/io_service/reset.html" rel="nofollow noreferrer"><code>_io_service->reset()</code></a> after the operations have finished. It should look like:</p>
<pre><code>_io_service->run_one();
if (_message_received)
{
timer.cancel();
}
else if (_timeout_triggered)
{
_socket->cancel();
}
_io_service->reset();
</code></pre>
<p>After some testing, I have checked that this kind of solution alone is not working. The <code>handle_timeout</code>method is being called continuously with the error code <code>operation_aborted</code>. How can these calls be stopped?</p>
<h2><strong>FIX PROPOSAL #2</strong></h2>
<p>The answer by <a href="https://stackoverflow.com/users/1053968/twsansbury">twsansbury</a> is accurate and based onto solid documentation basis. That implementation leads to the following code within the <code>async_read_helper</code>:</p>
<pre><code>while (_io_service->run_one())
{
if (_message_received)
{
timer.cancel();
}
else if (_timeout_triggered)
{
_socket->cancel();
}
}
_io_service->reset();
</code></pre>
<p>and the following change to the <code>handle_read</code> method:</p>
<pre><code>void communications_client::handle_read(const boost::system::error_code & error, size_t bytes_transferred)
{
if (error != boost::asio::error::operation_aborted)
{
...
}
}
</code></pre>
<p>This solution has proved solid and correct during testing.</p>

Reclassing an instance in Python
|
<p>I have a class that is provided to me by an external library. I have created a subclass of this class. I also have an instance of the original class.</p>
<p>I now want to turn this instance into an instance of my subclass without changing any properties that the instance already has (except for those that my subclass overrides anyway).</p>
<p>The following solution seems to work.</p>
<pre><code># This class comes from an external library. I don't (want) to control
# it, and I want to be open to changes that get made to the class
# by the library provider.
class Programmer(object):
def __init__(self,name):
self._name = name
def greet(self):
print "Hi, my name is %s." % self._name
def hard_work(self):
print "The garbage collector will take care of everything."
# This is my subclass.
class C_Programmer(Programmer):
def __init__(self, *args, **kwargs):
super(C_Programmer,self).__init__(*args, **kwargs)
self.learn_C()
def learn_C(self):
self._knowledge = ["malloc","free","pointer arithmetic","curly braces"]
def hard_work(self):
print "I'll have to remember " + " and ".join(self._knowledge) + "."
# The questionable thing: Reclassing a programmer.
@classmethod
def teach_C(cls, programmer):
programmer.__class__ = cls # <-- do I really want to do this?
programmer.learn_C()
joel = C_Programmer("Joel")
joel.greet()
joel.hard_work()
#>Hi, my name is Joel.
#>I'll have to remember malloc and free and pointer arithmetic and curly braces.
jeff = Programmer("Jeff")
# We (or someone else) makes changes to the instance. The reclassing shouldn't
# overwrite these.
jeff._name = "Jeff A"
jeff.greet()
jeff.hard_work()
#>Hi, my name is Jeff A.
#>The garbage collector will take care of everything.
# Let magic happen.
C_Programmer.teach_C(jeff)
jeff.greet()
jeff.hard_work()
#>Hi, my name is Jeff A.
#>I'll have to remember malloc and free and pointer arithmetic and curly braces.
</code></pre>
<p>However, I'm not convinced that this solution doesn't contain any caveats I haven't thought of (sorry for the triple negation), especially because reassigning the magical <code>__class__</code> just doesn't feel right. Even if this works, I can't help the feeling there should be a more pythonic way of doing this.</p>
<p>Is there?</p>
<hr>
<p>Edit: Thanks everyone for your answers. Here is what I get from them:</p>
<ul>
<li><p>Although the idea of reclassing an instance by assigning to <code>__class__</code> is not a widely used idiom, most answers (4 out of 6 at the time of writing) consider it a valid approach. One anwswer (by ojrac) says that it's "pretty weird at first glance," with which I agree (it was the reason for asking the question). Only one answer (by Jason Baker; with two positive comments & votes) actively discouraged me from doing this, however doing so based on the example use case moreso than on the technique in general.</p></li>
<li><p>None of the answers, whether positive or not, finds an actual technical problem in this method. A small exception is jls who mentions to beware of old-style classes, which is likely true, and C extensions. I suppose that new-style-class-aware C extensions should be as fine with this method as Python itself (presuming the latter is true), although if you disagree, keep the answers coming.</p></li>
</ul>
<p>As to the question of how pythonic this is, there were a few positive answers, but no real reasons given. Looking at the Zen (<code>import this</code>), I guess the most important rule in this case is "Explicit is better than implicit." I'm not sure, though, whether that rule speaks for or against reclassing this way.</p>
<ul>
<li><p>Using <code>{has,get,set}attr</code> seems more explicit, as we are explicitly making our changes to the object instead of using magic.</p></li>
<li><p>Using <code>__class__ = newclass</code> seems more explicit because we explicitly say "This is now an object of class 'newclass,' expect a different behaviour" instead of silently changing attributes but leaving users of the object believing they are dealing with a regular object of the old class.</p></li>
</ul>
<p>Summing up: From a technical standpoint, the method seems okay; the pythonicity question remains unanswered with a bias towards "yes." </p>
<p>I have accepted Martin Geisler's answer, because the Mercurial plugin example is a quite strong one (and also because it answered a question I even hadn't asked myself yet). However, if there are any arguments on the pythonicity question, I'd still like to hear them. Thanks all so far.</p>
<p>P.S. The actual use case is a UI data control object that needs to grow additional functionality <em>at runtime</em>. However, the question is meant to be very general.</p>

Wampserver icon not going green fully, mysql services not starting up?
|
<p>I'm running an application on <code>localhost</code>, it's been running successfully for at least a year now, but suddenly today wampserver isn't starting up. Whenever I rightclick on the taskbar icon and "start all services", it gets orange, but never green. Yesterday there was a data loss problem because one of the mysql tables crashed and had to be repaired, if that's related to this in any way.</p>
<p>If I try <code>http://localhost/phpmyadmin</code>, I get a <code>403 Forbidden</code> error, which I never got before.</p>
<p>I checked the apache log today and its latest entries are:</p>

<p>But now I don't know what to make of this. I made sure my.ini had specified port 3306, and it had (anyway noone changed it in a year how could it suddenly have another value). Any help please! I think Apache is working because when I type in <code>http://localhost</code>, it works and gives the option to go to phpmyadmin or my application folder, but it appears mysql services aren't starting up or something? I confirmed with the admin and no new software (such as Skype) have been installed or anything. </p>
<h2>Update</h2>
<p>I went to <code>Services.msc</code> and checked <code>wampapache</code>, the status was "started".
But <code>wampmysqld</code> had no status. So I right-clicked and chose "Start".
A message said "Windows is attempting to start the service on the local computer", but then I got this error: </p>
<pre><code>Windows could not start the wampmysqld service on Local Computer
Error 1067: The process terminated unexpectedly
</code></pre>
<p>What on earth is up? :(</p>
<h2>Update 2</h2>
<p>I got the mysql working again, here:</p>
<p><a href="https://stackoverflow.com/questions/17770846/mysqld-working-but-wampmysqld-not-starting-up/17770958#17770958">mysqld working but wampmysqld not starting up</a></p>
<p>HowEVER, <code>localhost://phpmyadmin</code> still gives me a <code>403 forbidden</code> error, and <code>mysql_connect</code> keeps giving me an "Access denied" error.</p>

How to force Java FX scene refresh?
|
<p>I have an Java FX scene with a start button and several rectangles which represent the tiles of a map. I also have drawn a sphere which represents my explorer (it has to explore the map), but I am having difficulties with running the animation.</p>
<p>In my OnMouseClicked handler for the start button, I start an algorithm for exploring the map which changes the position of the sphere and the colors of the tiles which have been visited. The problem is that the scene won't update itself while the algorithm is running, so I only get to see how the final scene will look like (after the algorithm has stopped running). How can I force a scene update so I can see all the color changes sequentially?</p>
<p>Later edit:</p>

<p>Initially all the rectangles are blue. The behavior I want to obtain here is to see the rectangles changing colors sequentially. The problem is that I only get to see the end result (all the rectangles change their color at the same time).</p>
