Testing Flutter code that uses a plugin and platform channel : <p>I have a flutter plugin which uses the platform channel to do some native work.</p> <p>How do I properly write tests for my application that requires this plugin?</p> <p>Unit tests only are good for pure dart functions. I don't believe Widget testing will be able to test things that use the platform channel to native. So that leaves integration testing.</p> <p>From what I understand is that integration testing will start your main application and you can control it around your app and test things.</p> <p>For my case, I want to test just the code that uses the plugin (that uses the platform channel for native stuff).</p> <p>Also what is important is the values that come back from the platform channel, so it is important to call the native side using a real platform channel and not a mock one.</p> <p>Is that possible? Can I tell the integration tester to open a dummy version of my application, kind of like an integrated widget tester?</p>

How to get lineno of "end-of-statement" in Python ast : <p>I am trying to work on a script that manipulates another script in Python, the script to be modified has structure like:</p> <pre><code>class SomethingRecord(Record): description = 'This records something' author = 'john smith' </code></pre> <p>I use <code>ast</code> to locate the <code>description</code> line number, and I use some code to change the original file with new description string base on the line number. So far so good.</p> <p>Now the only issue is <code>description</code> occasionally is a multi-line string, e.g.</p> <pre><code> description = ('line 1' 'line 2' 'line 3') </code></pre> <p>or</p> <pre><code> description = 'line 1' \ 'line 2' \ 'line 3' </code></pre> <p>and I only have the line number of the first line, not the following lines. So my one-line replacer would do</p> <pre><code> description = 'new value' 'line 2' \ 'line 3' </code></pre> <p>and the code is broken. I figured that if I know both the lineno of start and end/number of lines of <code>description</code> assignment I could repair my code to handle such situation. How do I get such information with Python standard library?</p>

Github showing (develop) branch behind master by x commits : <p>I have been searching for the answer to this problem but have not found a solution or explanation. </p> <p>We just switched to Github for our repo and are still trying to find the best way to use it in a team environment. Our current workflow is like this:</p> <p>We have two branches <code>develop</code> and <code>master</code></p> <ol> <li><p>Developer clones <code>develop</code> branch onto their machine and creates a branch using: <code>git clone https://github.com/username/repo</code></p></li> <li><p>Developer creates the branch for the feature they are working on using: <code>git checkout -b branchname</code></p></li> <li><p>Developer finishes branch and pushes to Github using: <code>git pull</code> then <code>git push -u origin branchname</code></p></li> <li><p>Developer creates pull request and the lead developer will first merge the just pushed branch into <code>develop</code> and then merges <code>develop</code> into <code>master</code></p></li> </ol> <p>Now the thing that concerns me and makes me wonder if we are doing something wrong is that when we look at the <code>master</code> branch in Github everything appears fine, but when we view the <code>develop</code> branch inside of Github it says <code>This branch is x commits behind master</code>. Everytime we merge a pull request the number <code>x</code> goes up. Github gives the option on the same line to "Compare" or create a "Pull Request" but when I click either of those options it shows the branches are identical.</p> <p>I have tried to fixed this previously by merging <code>master</code> into <code>develop</code> which does make the branches both even but as soon as a pull request is merged we get the same problem again. </p> <p>When we first switched to Github I don't ever recall seeing that <code>develop</code> was behind <code>master</code> but our workflow has not changed. I don't know if maybe I just didn't notice it before or not.</p> <p>If I compare the commits between the branches I can see that in fact <code>develop</code> is behind <code>master</code> by <code>x</code> number of commits. The commits that are showing up are the ones where I merge <code>develop</code> into <code>master</code>. What I am wondering is if it is something to be concerned about? The branches are identical besides the number of commits. Are we not using Git/Github correctly and is that why we are getting this, or is this a normal thing?</p>

Fit mixture of Gaussians with fixed covariance in Python : <p>I have some 2D data (GPS data) with clusters (stop locations) that I know resemble Gaussians with a characteristic standard deviation (proportional to the inherent noise of GPS samples). The figure below visualizes a sample that I expect has two such clusters. The image is 25 meters wide and 13 meters tall.</p> <p><a href="https://i.stack.imgur.com/cECqI.png" rel="noreferrer"><img src="https://i.stack.imgur.com/cECqI.png" alt="enter image description here"></a></p> <p>The <code>sklearn</code> module has a function <a href="http://scikit-learn.org/stable/modules/generated/sklearn.mixture.GaussianMixture.html#sklearn.mixture.GaussianMixture.fit" rel="noreferrer"><code>sklearn.mixture.GaussianMixture</code></a> which allows you to fit a mixture of Gaussians to data. The function has a parameter, <code>covariance_type</code>, that enables you to assume different things about the shape of the Gaussians. You can, for example, assume them to be uniform using the <code>'tied'</code> argument.</p> <p>However, it does not appear directly possible to assume the covariance matrices to remain constant. From the <code>sklearn</code> source code it seems trivial to make a modification that enables this but it feels a bit excessive to make a pull request with an update that allows this (also I don't want to accidentally add bugs in <code>sklearn</code>). Is there a better way to fit a mixture to data where the covariance matrix of each Gaussian is fixed?</p> <p>I want to assume that the SD should remain constant at around 3 meters for each component, since that is roughly the noise level of my GPS samples.</p>

Can getDrawable() throw a NullPointerException? : <p>I have a class extending ImageView. In it, I have a function that calls <code>getDrawable().getIntrinsicWidth();</code>. I have about 100 000 installs, and I have 10 reports of this line producing a nullpointerexception. I can't reproduce this, but would still like to fix this. For this, I need to know what throws it, but I can't test it.</p> <p>Can I safely assume that getDrawable() can not throw a nullpointer exception, but returns null for some reason, so getIntrinsicWidth() throws the exception? </p> <p>Also, why would it return null, unless it was set to null? I set the image only by from ShareIntents, and I filter by mimetyp "image/*". If the Uri wasn't pointing to an image, wouldn't that get sorted out during the sharing process? Or do I need to take care of that myself?</p>

Need help defining the getPrice method in this subclass : //I am trying to determine how I should define the getPrice method. The shirts can range from Small to XXXL and the price varies. The price is determined by the size: $22.99 for XXL or XXXL, and $19.99 for all other sizes. There are two other classes that I have complied.

Sequencing of function parameter destruction : <p>According to C++14 [expr.call]/4:</p> <blockquote> <p>The lifetime of a parameter ends when the function in which it is defined returns.</p> </blockquote> <p>This seems to imply that a parameter's destructor must run before the code which called the function goes on to use the function's return value. </p> <p>However, this code shows differently:</p> <pre><code>#include &lt;iostream&gt; struct G { G(int): moved(0) { std::cout &lt;&lt; "G(int)\n"; } G(G&amp;&amp;): moved(1) { std::cout &lt;&lt; "G(G&amp;&amp;)\n"; } ~G() { std::cout &lt;&lt; (moved ? "~G(G&amp;&amp;)\n" : "~G()\n"); } int moved; }; struct F { F(int) { std::cout &lt;&lt; "F(int)\n"; } ~F() { std::cout &lt;&lt; "~F()\n"; } }; int func(G gparm) { std::cout &lt;&lt; "---- In func.\n"; return 0; } int main() { F v { func(0) }; std::cout &lt;&lt; "---- End of main.\n"; return 0; } </code></pre> <p>The output for gcc and clang , with <code>-fno-elide-constructors</code>, is (with my annotations):</p> <pre><code>G(int) // Temporary used to copy-initialize gparm G(G&amp;&amp;) // gparm ---- In func. F(int) // v ~G(G&amp;&amp;) // gparm ~G() // Temporary used to copy-initialize gparm ---- End of main. ~F() // v </code></pre> <p>So, clearly <code>v</code>'s constructor runs before <code>gparm</code>'s destructor. But in MSVC, <code>gparm</code> is destroyed before <code>v</code>'s constructor runs.</p> <p>The same issue can be seen with copy-elision enabled, and/or with <code>func({0})</code> so that the parameter is direct-initialized. <code>v</code> is always constructed before <code>gparm</code> is destructed. I also observed the issue in a longer chain, e.g. <code>F v = f(g(h(i(j())));</code> did not destroy any of the parameters of <code>f,g,h,i</code> until after <code>v</code> was initialized.</p> <p>This could be a problem in practice, for example if <code>~G</code> unlocks a resource and <code>F()</code> acquires the resource, it would be a deadlock. Or, if <code>~G</code> throws, then execution should jump to a catch handler without <code>v</code> having been initialized.</p> <p>My question is: does the standard permit both of these orderings? . Is there any more specific definition of the sequencing relationship involving parameter destruction, than just that quote from expr.call/4 which does not use the standard sequencing terms?</p>

How to refresh the page after a ServiceWorker update? : <p>I've consulted a lot of resources on Service Workers:</p> <ul> <li><a href="https://jakearchibald.com/2014/using-serviceworker-today/#updating-your-serviceworker" rel="noreferrer">Updating your ServiceWorker</a></li> <li><a href="https://ponyfoo.com/articles/serviceworker-revolution" rel="noreferrer">ServiceWorker: Revolution of the Web Platform</a></li> <li>Jake Archibald's lovely <a href="https://github.com/jakearchibald/svgomg/blob/6c21157b65dd779bbf2dd2adf9831aaf71d4bb08/src/js/sw/index.js" rel="noreferrer">SVGOMG</a>. </li> </ul> <p>However, I can't for the life of me figure out how to update the page after a new ServiceWorker has been installed. No matter what I do, my page is stuck on an old version, and only a hard refresh (Cmd-Shift-R) will fix it. No combination of 1) closing the tab, 2) closing Chrome, or 3) <code>location.reload(true)</code> will serve the new content.</p> <p>I have a <a href="https://github.com/nolanlawson/serviceworker-update-demo" rel="noreferrer">super simple example app</a> mostly based on SVGOMG. On installation, I cache a bunch of resources using <code>cache.addAll()</code>, and I also do <code>skipWaiting()</code> if the current version's major version number doesn't match the active version's number (based on an IndexedDB lookup):</p> <pre><code>self.addEventListener('install', function install(event) { event.waitUntil((async () =&gt; { var activeVersionPromise = localForage.getItem('active-version'); var cache = await caches.open('cache-' + version); await cache.addAll(staticContent); var activeVersion = await activeVersionPromise; if (!activeVersion || semver.parse(activeVersion).major === semver.parse(version).major) { if (self.skipWaiting) { // wrapping in an if while Chrome 40 is still around self.skipWaiting(); } } })()); }); </code></pre> <p>I'm using a semver-inspired system where the major version number indicates that the new ServiceWorker can't be hot-swapped for the old one. This works on the ServiceWorker side - a bump from v1.0.0 to v1.0.1 causes the worker to be immediately installed on a refresh, whereas from v1.0.0 to v2.0.0, it waits for the tab to be closed and reopened before being installed.</p> <p>Back in the main thread, I'm manually updating the ServiceWorker after registration &ndash; otherwise the page never even gets the memo that there's a new version of the ServiceWorker available (oddly I found very few mentions of this anywhere in the ServiceWorker literature):</p> <pre><code>navigator.serviceWorker.register('/sw-bundle.js', { scope: './' }).then(registration =&gt; { if (typeof registration.update == 'function') { registration.update(); } }); </code></pre> <p>However, the content that gets served to the main thread is always stuck on an old version of the page ("My version is 1.0.0"), regardless of whether I increment the version to 1.0.1 or 2.0.0.</p> <p>I'm kind of stumped here. I was hoping to find an elegant semver-y solution to ServiceWorker versioning (hence my use of <code>require('./package.json').version</code>), but in my current implementation, the user is perpetually stuck on an old version of the page, unless they hard-refresh or manually clear out all their data. :/</p>

Should my Django site's main page be an app? : <p>I have finished reading the Django official tutorial which teaches how to create a simple polls app, which is the way they chose to teach beginners the Django basics. My question is, now that I know how to make a simple app and want to create my own website (using Django), should the main (front) page of my website, be an app as well? If so, how do people usually call it and configure it? I mean, it should do nothing but render a html template, so why make it so complicated? If not, where do I put all the static files and how do I reference them? I am a bit confused and could use your help. Maybe I misunderstood Django's main use?</p>
