• How to merge branches in Git by "hunk"

  - by user1316464

  Here's the scenario. I made a "dev" branch off the "master" branch and made a few new commits. Some of those changes are going to only be relevant to my local development machine. For example I changed a URL variable to point to a local apache server instead of the real URL that's posted online (I did this for speed during the testing phase). Now I'd like to incorporate my changes from the dev branch into the master branch but NOT those changes which only make sense in my local environment. I'd envisioned something like a merge --patch which would allow me to choose the changes I want to merge line by line. Alternatively maybe I could checkout the "master" branch, but keep the files in my working directory as they were in the "dev" branch, then do a git add --patch. Would that work?

Here is the exact scenerio- I have a class two classes A and B and A has a private object of B and in a method of A i am internally calling the method of B and then doing some calculation and returning the result. Can i mock the method of B in this scenerio? Please try to give me full detail about the conditions where i can mock the methods and functions of the class. Thanx

• TCP 30 small packets per second polutes connection with server

  - by Denis Ermolin

  I'm testing connection with flash client and cloud server(boost::asio for software) over TCP connection. My connection with server already is really poor - 120 ms ping in average. I found when i start to send packets with 2 bytes size (without tcp header) with speed 30 packets/s ping grow to 170-200 average. I think that it's really bad and my bad connection and bad cloud provider is reason for this high ping without any load. What do you think? (I tested my software and can compute about 50k packets/s so software is not a problem).

• Is there a slick way to deploy my silverlight app and change settings programmatically?

  - by MIke S.

  I am fairly new to web development. I am at the point of deployment (for testing). I have a few places (maybe 4 places) where I had to add a URI that was non-relative into the appliation. So now, at deployment, those need to be changed. Is there a slick way of handling this? By slick I mean not manually going through the app and changing the URIs or a blanket find and replace (too risky). I only have 4 places to change now, but this could easily change and cause deployment issues. I am using a Microsoft technology stack. Silverlight, ASP.NET, RIA, etc. Development is done in Visual Studio 2010. I noticed that the web projects have a nifty transformation for the web.config...which is nice. Is there an equivalent mechanism for silverlight resources? Any other ways? Any thoughts?

• jQuery Swap Image on Click and if/else

  - by jrutter

  Im stuck, Im setting a variable when someone clicks, then testing with if to see if the variable exists and doing something else. Its a simple script which Im probably overthinking, would love someone's thoughts. $('.view-alternatives-btn').live('click', function() { //$("#nc-alternate-wines").scrollTo(); //$('.nc-remove').toggle(); var showBtn = null; if (showBtn == null) { $('.view-alternatives-btn img').attr("src","../images/wsj_hide_alternatives_btn.gif"); $('#nc-alternate-wines').show(); showBtn = 1; console.log(showBtn); } else if (showBtn == 1) { $('.view-alternatives-btn img').attr("src","../images/wsj_view_alternatives_btn.gif"); $('#nc-alternate-wines').hide(); console.log("this " + showBtn); } return false; });

• What is the '@(' doing in this Perl code?

  - by Anthony Veckey

  In this code snippet: use strict; use warnings; use Data::Dumper; my $r = [qw(testing this thing)]; print Dumper($r); foreach my $row (@({$r}) { print "$row\n"; $row .= 'mod'; } print Dumper($r); print Dumper(@({$r}); I figured out that the '(' after the '@' in the foreach is causing this not to loop correctly. I have no idea why this code even works as there is no ending parenthesis. What is this doing? It looks to be creating a new variable on the fly, but shouldn't 'use strict' have fired or something? Please help explain what that '@(' is doing and why it still runs without an ending parenthesis.

• Can I use MFC objects in STL containers?

  - by Jesse Stimpson

  The following code doesn't compile for me in MSVC2005: std::vector<CMenu> vec(10); CMenu is an MFC menu object (such as a context menu). Through some testing I learned that CMenu does not have a public copy constructor. To do what I wanted to do, I needed to use a dynamic array. CMenu* menus = new CMenu[10]; // ... delete [] menus; Of course, now I've lost all the benefits of using an STL container. Do I have any other options?

• Jmeter Query new user

  - by Sri

  First of all apologies for the below question. Am from a Testing background for the past 8 years and very novice to Jmeter. I went through the Jmeter site, and ran a sample recording using the jmeter.apache.org site and it went fine. I want to test my knowledge and understanding. So, I did the following way. Created a thread group. Added a config element HTTP Default Requests with server name as mail.google.com. Added a Sampler as HTTP request, set the METHOD to POST and gave the username and password, and i ran the test. When i see the Results Viewer, i could see the login page of gmail, I need to know how to pass my username and password and simulate the clicking of Submit button and getting the next page. Please help, am very new and will really appreciate if it's explained as simple as possible.

• Patterns for avoiding jQuery silent fails

  - by Matias

  Is there any good practice to avoid your jQuery code silently fail? For example: $('.this #is:my(complexSelector)').doSomething(); I know that every time this line get executed, the selector is intended to match at least one element, or certain amount of elements. Is there any standard or good way to validate that? I thought about something like this: var $matchedElements = $('.this #is:my(complexSelector)'); if ($matchedElements.length < 0) throw 'No matched elements'; $matchedElements.doSomething(); Also I think unit testing would be a valid option instead of messing the code. My question may be silly, but I wonder whether there is a better option than the things that I'm currently doing or not. Also, maybe I'm in the wrong way checking if any element match my selector. However, as the page continues growing, the selectors could stop matching some elements and pieces of functionality could stop working inadvertently.

• Application wide messaging... without singletons?

  - by StormianRootSolver

  So, I want to go for a more Singleton - less design in the future. However, there seem to be a lot of tasks in an application that can't be done in meaningful way without singletons. I call them "application wide services", but they also fall into the same category as the cross cutting concerns, which I usually fix via AOP. Lets take an example: I want an application wide message queue that dispatches messages to components, every component can subscribe and publish there, it's a very nice multicast thing. The message queue and dispatching system are usually a (rather short) singleton class, which is very easy to implement in, say, C#. You can even use double dispatching and utilize message type metadata and the like, it's all so easy to do, it's almost trivial. However, having singletons is not really "object oriented design" (it introduces global variables) and it makes testing harder. Do you have any ideas? I'm asking this question because I'm willing to learn more about this topic, a LOT more. :-)

• Parent Thread exiting before Child Threads [python]

  - by crgwbr

  I'm using Python in a webapp (CGI for testing, FastCGI for production) that needs to send an occasional email (when a user registers or something else important happens). Since communicating with an SMTP server takes a long time, I'd like to spawn a thread for the mail function so that the rest of the app can finish up the request without waiting for the email to finish sending. I tried using thread.start_new(func, (args)), but the Parent return's and exits before the sending is complete, thereby killing the sending process before it does anything useful. Is there anyway to keep the process alive long enough for the child process to finish?

• In XHR, is it possible to distinguish network errors from cross-origin errors?

  - by greim

  http://www.w3.org/TR/access-control/ Reading the CORS spec linked above, it seems to be the case that it's impossible to reliably distinguish between a generic "network error" and a cross-origin access denied error. From the spec: If there is a network error Apply the network error steps. Perform a resource sharing check. If it returns fail, apply the network error steps. http://www.w3.org/TR/access-control/#simple-cross-origin-request0 In my testing, I couldn't locate any features of Firefox's implementation that seem to indicate that the resource sharing check definitely failed. It just switches readyState to 4 and sets status to 0. Ultimately I'd like the ability to pass a success callback, a general fail callback, and an optional cross-origin fail callback, to my function. Thanks for any help or insight.

• Online compilers/runtime for Java, C++, Python and ObjC?

  - by Nocturne

  Does anyone know of a good online compiler/runtime (for C++, Java, Python, ObjC etc.) that I can access on the web? What I'm looking for is something that would allow me to type in a program in a web form and to run the program and see the results online. (Let's not get into the why for now. Suffice it to say for the moment that I don't always have access to a compiler/runtime, and firing up an IDE is just overkill for testing out some code snippets) I know of codepad.org -- but I'm looking for something better.

• Empty Post with JQuery Ajax Post

  - by chandru

  Hi, I am getting a some unusual problem with JQuery ajax. I am using IIS to host my web application and I have http handler for which I have enabled only POST verb on it. Using JQuery ajax, I am posting data to this http handler, this is working fine in our development and testing environment and also most of the time on production environment as well. But sometimes we are getting empty post data on to the server. When we look into the csBytes on IISLog we found that it was very less compare to other success post requests. We are using JSON.js to convert the javascript object back to raw json string and latest jquery.1-3.js for posting to server. Anbody know why this is happening?

• Mock Objects properties not changing

  - by frictionlesspulley

  I am new to using Mock test in .Net. I am testing out a financial transaction which is of the following nature: int amt =20; //sets all the props and func and returns a FinaceAccount. //Note I did not SetUp the amt of the account. var account =GetFinanceAccount() //service layer to be tested _financeService.tranx(account,amt); //checks if the amt was added to the account.amt //here the amt comes out same as that set in GetFinanceAccount. Assert.AreEqual(account.amt ,amt) I know that the function tranx works correctly but there is an issue with the test. Are there any GOOD reference material on Mocking in .Net

• PHP+MYSQL Server Config

  - by Matias

  Hi guys, I am parsing an XML file with PHP and inserting the rows in a MYSQL database. I am using PHP simplexml_load_files to load the XML and a foreach to loop through the array and insert the rows into my database. It works perfectly fine with small files i am testing, but it comes to reality I need to parse a large 500mb XML file and nothing happens. I was wondering what was the right Php.ini config for this case ? I have a VPS Linux Cent OS, with 256 mb of dedicated Memory and MYSQL 5.0.5. I have also set php memory_limit = 256M (maximum of my server) Any suggestions, similar experiences will be greatly appreciated Thanks

• HTML5 video element non-seekable when using Django development server

  - by Ory Band

  Hey everyone. I've got a Django app serving a webpage with an HTML5 element. There's a wierd "feature", turning the video element to be non-seekable: video.seekable returns a timeRanges object with length=0, whereas it should be length=1. This means I can't edit the video. JavaScript can't do anything either. The thing is, when I upload the problematic webpage, statically - no Django, just plain HTML/JS/CSS - to my website for testing, it works fine - length=1. However, if I try to serve the same static page on my Django dev server still gives the same problem. I am using Django's static serving for dev/debug purposes - Do you have any idea what is causing this, or how can I fix it? Thanks.

  I'm running windows xp and I've got MiniMagick and ImageMagick installed (latest versions). I'm now using the console to test out that everything works. Using the ms command prompt image magick works no problem. I'm testing this by using the identify command. Now, when I try to use MiniMagick from the console by entering image = MiniMagick::Image.new('image.jpg') It returns MiniMagickError, "ImageMagick command ("identify \"input.jpg\"") failed: {:status_code = #"'identify' is not recognized as an internal or external command,\noperable program or batch file.\n"} Can anybody help?

• Google Play: how dev can give (already purchased) app to customer as a gift?

  - by Tertium

  Yes, SO, I know, it's not a "programmer's" question:) But customers sometimes help us (devs) with our code, so we (devs) shold be grateful. I think answer to my question will be useful for all fellow android devs. User has purchased my app. Refund period (15min) is over of course. Now I'd like to return money to him as a gift, because he helped me in testing a little. If I refund the entire order in Checkout-Orders will user keep my app 'purchased'? I mean will he be able to uninstall and install it again from GooglePlay-MyApps and will app be marked "purchased"? Will Google LVL accept him to run the app? I've done such refunds before, but then they called it "Android Market", and refund was 12h, and there were no LVL. Maybe somebody know another way to make a small gift using Google Play?

• Aptana Studio is opening but not ever closing a python.exe process

  - by SC Ghost

  I am developing a small testing website using Django 1.2 in Aptana Studio build 2.0.4.1268158907. I have a Django project that I test by running the command "runserver 8001" on my project. This command runs the project on a small server that comes with Django. However the problem arises that every time I run this command Aptana opens two instances of the process "python.exe". Upon terminating the command only one of these instances is ended. The other process continues to run and use memory. My server is not online, and the process doesn't seem to do anything that I can find. This happens every time i run the runserver command on my project and therefore more and more python.exe instances will open up through my development period. Any help discovering either the purpose of this extra python.exe or a way to prevent it from opening would be much appreciated.

• What non-standard behaviour features does Gmail exhibit, when it is programmatically used as a POP3 server?

  - by Mike Green

  I am trying to prepare a complete list of behaviour that Gmail POP3 exhibits, that you wouldn’t expect to generally find in a POP3 server. For example, Gmail appears to ignore the DELE (delete) command from a POP3 client. Instead, it implements its own delete and archive strategy. The purpose of preparing a list is to avoid developers testing a POP3 client against the Gmail POP3 server and then assuming that all POP3 servers behave in the same way. Can anyone provide a more complete list of non-standard behaviour?

• How do I get stdout into mstest output when running in new app domain?

  - by btlog

  I have been working on test framework, which creates a new app domain to run the tests in. The primary reason being the dll's that we are testing has some horrible code that relies on the dll being located in the app domain path. (No I can't change this code.) The problem that I am having is that my test team is writing a bunch of functional tests in mstest and one of the loggers, that writes to Console.Out, does not have any of the log information captured in the trx output. When running the code through a console app all of the log information is output fine. So do the other loggers that have been implemented. My thought is that mstest is setting its own TextWriter to Console.Out, but the new app doamin has it's own TextWriter for Console.Out as the new app domain has it's own set of statics. I appreciate your ideas.
