  • Git push current branch to a remote with Heroku

    - by cmaughan
    I'm trying to create a staging branch on Heroku, but there's something I don't quite get. Assuming I've already created a heroku app and setup the remote to point to staging-remote, If I do: git checkout -b staging staging-remote/master I get a local branch called 'staging' which tracks staging-remote/master - or that's what I thought.... But: git remote show staging-remote Gives me this: remote staging Fetch URL: [email protected]:myappname.git Push URL: [email protected]:myappname.git HEAD branch: master Remote branch: master tracked Local branch configured for 'git pull': staging-remote merges with remote master Local ref configured for 'git push': master pushes to master (up to date) As you can see, the pull looks reasonable, but the default push does not. It implies that if I do: git push staging-remote I'm going to push my local master branch up to the staging branch. But that's not what I want.... Basically, I want to merge updates into my staging branch, then easily push it to heroku without having to specify the branch like so: git push staging-remote mybranch:master The above isn't hard to do, but I want to avoid accidentally doing the previous push and pushing the wrong branch... This is doubly important for the production branch I'd like to create! I've tried messing with git config, but haven't figured out how to get this right yet...

  • Why can't I debug my ASP project through a remote desktop connection?

    - by Anthony Benavente
    I just asked this question in Stack Overflow but I figured this stack exchange forum is a better fit. It's been about a month of trying to figure out this problem and we've still not found a solution. We have about seven virtual machines on a server running Windows XP Professional w/ SP 3 all with Visual Studio Interdev and IIS 5.1 installed. Running the programs all work fine, but we just can't debug through remote desktop. When we are logged into the server console (through VM Sphere) and log into one of the virtual machines through there, we are able to debug properly. We figured the issue lies with some kind of permissions for Remote Desktop Users. We've tried nearly every article on the internet (exaggerating of course) and are about to give up hope. One more thing, when we are logged into the virtual machine through the server console and then remote in, the user that was logged into the console is kicked off but debugging works! Does remoting in trick the computer into giving us the correct permissions? I'm really not sure how it works. I know that this technology predates human history, but we are in the process of migrating from ASP Classic to ASP.NET Specs: - Windows XP Professional W/ SP3 - IIS 5.1 - Visual Studio 6 Interdev EDIT: By "debug" I mean running the project with breakpoints. Interdev doesn't stop at breakpoints.

  • What's ideal debugging setup? window placement etc.

    - by Padmarag
    I am interested in knowing Debugging setup that'll allow me to be most productive. I am mainly interested in knowing how and where you place different windows like the variables window, code window, the stack. Also possibly the relative size of different windows. I'd prefer if there are screenshots attached and a description of why the setup works for you. I mainly use Eclipse and Netbeans. PS: I am open to making this community wiki if needed.

  • Tools for Debugging ThreadPool Issues in Visual Studio 2010.

    - by ProfK
    I have never spent much time debugging multithreaded .NET apps (or others), and have quite a simple one to solve very quickly. Ideally I would imagined and would lurve to be able to intercept thread creation and use by worker objects, so that nothing unexpected happens while I'm on a breakpoint in my thread. Is that realistic? What else is there in VS 2010?

  • Printing Variable names and contents as debugging tool; looking for emacs/Python shortcut

    - by Schof
    I find myself adding debugging "print" statements quite often -- stuff like this: print("a_variable_name: %s" % a_variable_name) How do you all do that? Am I being neurotic in trying to find a way to optimize this? I may be working on a function and put in a half-dozen or so of those lines, figure out why it's not working, and then cut them out again. Have you developed an efficient way of doing that? I'm coding Python in Emacs.

  • Attach certificate to remote desktop connection - not gateway services

    - by Jordan S
    I have a Windows server that I want to attach a 3rd party signed certificate for remote desktop connections. This is not a remote desktop services server, i.e. it is just remote desktop administration. There is lots of info on the internet about attaching a certificate to remote desktop services, but I want to attach mine to just plain remote desktop connection for administration purposes. If anyone know how to do this, please holler! I have imported the certificate into the Remote Desktop store in the certificates mmc snap in, and have tried running the wmic command in this question (Configure custom SSL certificate for RDP on Windows Server 2012 in Remote Administration mode?) but this fails. THANKS!

  • SQL Developer Debugging, Watches, Smart Data, & Data

    - by thatjeffsmith
    After presenting the SQL Developer PL/SQL debugger for about an hour yesterday at KScope12 in San Antonio, my boss came up and asked, “Now, would you really want to know what the Smart Data panel does?” Apparently I had ‘made up’ my own story about what that panel’s intent is based on my experience with it. Not good Jeff, not good. It was a very small point of my presentation, but I probably should have read the docs. The Smart Data tab displays information about variables, using your Debugger: Smart Data preferences. You can also specify these preferences by right-clicking in the Smart Data window and selecting Preferences. Debugger Smart Data Preferences, control number of variables to display The Smart Data panel auto-inspects the last X accessed variables. So if you have a program with 26 variables, instead of showing you all 26, it will just show you the last two variables that were referenced in your program. If you were to click on the ‘Data’ debug panel, you’ll see EVERYTHING. And if you only want to see a very specific set of values, then you should use Watches. The Smart Data Panel As I step through the code, the variables being tracked change as they are referenced. Only the most recent ones display. This is controlled by the ‘Maximum Locations to Remember’ preference. Step through the code, see the latest variables accessed The Data Panel All variables are displayed. Might be information overload on large PL/SQL programs where you have many dozens or even hundreds of variables to track. Shows everything all the time Watches Watches are added manually and only show what you ask for. Data on Demand – add a watch to track a specific variable Remember, you can interact with your data If you want to do more than just watch, you can mouse-right on a data element, and change the value of the variable as the program is running. This is one of the primary benefits to debugging over using DBMS_OUTPUT to track what’s happening in your program. Change the values while the program is running to test your ‘What if?’ scenarios

  • A debugging experience with "highly compatible" ASP.NET 4.5

    - by Jeff
    I have to admit that I will pretty much upgrade software for no reason other than being on the latest version. I won't do it if it's super expensive (Adobe gets money from me about once every three or four years at best), but particularly with frameworks and stuff generally available as part of my MSDN subscription, I'll be bleeding edge. CoasterBuzz was running on the MVC 4 framework pretty much as soon as they did a "go live" license for it. I didn't really jump in head-first with Windows 8 and Visual Studio 2012, in part because I just wasn't interested in doing the reinstalls for each new version. Turns out there weren't that many revisions anyway. But when the final versions were released a week and a half ago, I jumped in. I saw on one of the Microsoft sites that .Net 4.5 was a "highly compatible in-place update" to the framework. Good enough for me. I was obviously running it by default in Windows 8, and installed it on my production server. I suppose it's "highly compatible," except when it isn't. Three of my sites are running with various flavors of the MVC version of POP Forums. All of them stopped working under ASP.NET 4.5. It was not immediately obvious what the problem might be beyond an exception indicating that there were no repository classes registered with Ninject, which I use for dependency injection in the forums. This was made all the more weird by the fact that it ran fine locally in the dev Web host. My first instinct was to spin up a Windows Server VM on my local box and put the remote debugger on it. (Side note: running multiple VM's on a Retina MacBook Pro with 16 gigs of RAM is pretty much the most awesome thing ever. I can't believe this computer is for real, and not a 50-pound tower under my desk.) What might have been going on in IIS that doesn't happen in Visual Studio? In the debugging process, I realized that I might be looking in the wrong place. POP Forums creates a Ninject container using a method called from a PreApplicationStartMethod attribute, and at that time registers a module (what Ninject uses to map interfaces to implementations) that maps all of the core dependencies. It also creates an instance of an HttpModule that originally hosted the "services" (search indexing, mailer, etc.), but now just records errors. That's all well and good, but the actual repository mapping, where data is actually read or persisted, happens in Application_Start() in global.asax. The idea there is that you can swap out the SqlSingleWebServer repos for something tuned for multiple servers, Oracle or something else. Of course, if I used something like StructureMap, which does convention-based mapping for dependency injection (a class implementing ISettingsRepository called SettingsRepository is automagically mapped), I wouldn't have to worry about it. In any case, the HttpModule, being instantiated before Application_Start() gets to run, would throw because there was no repo mapped where it could get settings from the database. This makes total sense. The fix is sort of a hack, where I don't setup the innards of the HttpModule until a call to its BeginRequest is made. I say it's a hack, because its primary function, logging exceptions, won't work until the app has warmed up. Still, this brings up an interesting question about the race condition, and what changed in 4.5 when it's running in IIS. In ASP.NET 4, it would appear that the code called via the PreApplicationStartMethod was either failing silently, and running again later, or it was getting to that code after Application_Start was called. In any case, weird thing. The real pain point I'm experiencing now is a bug in MVC 4 that is extremely serious because it renders the mobile/alternate view functionality very much broken.

  • teamviewer in "client only" mode

    - by Tommy
    I have a remote PC with the teamviewer on it. I want to use my local teamviewer installation only for connecting to that remote PC, and I don't want any services (teamviewerd) running on my local Ubuntu 14.04. I've tried to disable the service by doing sudo teamviewer --daemon disable but after that I'm not able to connect to the remote PC, because teamviewer reports an error "The Teamviewer daemon is not running!" on start, and I'm not able to access the gui. Is there a way to connect to the remote PC with teamviewer with no teamviewerd running?

  • SSH'ing to my machine attaches an existing screen session and detaching it ends my SSH session

    - by jsplaine
    ssh'ing to my Ubuntu machine automatically attaches an existing screen session and detaching ends my ssh session What I want is to be able to ssh to my Ubuntu machine without automatically attaching to the screen session on that machine. Or at least, I should be able to to detach from that screen session w/o ending my ssh session .. right? Doesn't seem to work. This so that I can attempt to run firefox --display <whichever one is being forwarded to my ssh session>, so that I can debug a website that the remote Ubuntu machine is running (via localhost). Best case scenario is that I could just remote-desktop to my Ubuntu machine. But it's not set up to allow remote-desktop, and I see no way to set it up remotely via shell/ssh. Also, it sounds like you need a static IP in order to remote desktop to an Ubuntu machine (so I keep reading).

  • SSIS Debugging Tip: Using Data Viewers

    - by Jim Giercyk
    When you have an SSIS package error, it is often very helpful to see the data records that are causing the problem.  After all, if your input has 50,000 records and 1 of them has corrupt data, it can be a chore.  Your execution results will tell you which column contains the bad data, but not which record…..enter the Data Viewer. In this scenario I have created a truncation error.  The input length of [lastname] is 50, but the output table has a length of 15.  When it runs, at least one of the records causes the package to fail.     Now what?  We can tell from our execution results that there is a problem with [lastname], but we have no idea WHICH record?     Let’s identify the row that is actually causing the problem.  First, we grab the oft’ forgotten Row Count shape from our toolbar and connect it to the error output from our input query.  Remember that in order to intercept errors with the error output, you must redirect them.     The Row Count shape requires 1 integer variable.  For our purposes, we will not reference the variable, but it is still required in order for the package to run.  Typically we would use the variable to hold the number of rows in the table and refer back to it later in our process.  We are simply using the Row Count as a “Dead End” for errors.  I called my variable RowCounter.  To create a variable, with no shapes selected, right-click on the background and choose Variable.     Once we have setup the Row Count shape, we can right-click on the red line (error output) from the query, and select Data Viewers.  In the popup, we click the add button and we will see this:     There are other fancier options we can play with, but for now we just want to view the output in a grid.  WE select Grid, then click OK on all of the popup windows to shut them down.  We should now see a grid with a pair of glasses on the error output line.     So, we are ready to catch the error output in a grid and see that is causing the problem!  This time when we run the package, it does not fail because we directed the error to the Row Count.  We also get a popup window showing the error record in a grid.  If there were multiple errors we would see them all.     Indeed, the [lastname] column is longer than 15 characters.  Notice the last column in the grid, [Error Code – Description].  We knew this was a truncation error before we added the grid, but if you have worked with SSIS for any length of time, you know that some errors are much more obscure.  The description column can be very useful under those circumstances! Data viewers can be used any time we want to see the data that is actually in the pipeline;  they stop the package temporarily until we shut them.  Also remember that the Row Count shape can be used as a “Dead End”.  It is useful during development when we want to see the output from a dataflow, but don’t want to update a table or file with the data.  Data viewers are an invaluable tool for both development and debugging.  Just remember to REMOVE THEM before putting your package into production

  • Connecting to an Amazon AWS database [closed]

    - by Adel
    so I'm a bit overwhelmed/bewildered by the whole concept of networking/remote-desktop , etc. The context is that - in my company I need to access a remote database. The standard way I use is to first connect using a VPN-Client( called Shrew Soft Access manager), then once that says: "network device configured tunnel enabled" I'm good to connect using windows "Remote Desktop Connection" . But now our company set up an Amazon AWS database, and I'm told I need to connect, and I ony need to use RDP. So I tried the standard windows one - but it doesn't work. On wikipedia , I looked up remote desktop sftware and downloaded one called VNC Viewer. but it doesn't work. Any advice/tips/comments appreciated EDIT: YAYA! I finally got a little more connected . I had to use my username as a fully qualified name: Computer: XYZ.XYZ.XYZ.XYZ USERNAME: XYZ.XYZ.XYZ.XYZ\aazzam

  • Looking at desktop virtualization, but some users need 3D support. Is HP Remote Graphics a viable solution?

    - by Ryan Thompson
    My company is looking at desktop virtualization, and are planning to move all of the desktop compute resources into the server room or data center, and provide users with thin clients for access. In most cases, a simple VNC or Remote Desktop solution is adequate, but some users are running visualizations that require 3D capability--something that VNC and Remote Desktop cannot support. Rather than making an exception and providing desktop machines for these users, complicating out rollout and future operations, we are considering adding servers with GPUs, and using HP's Remote Graphics to provide access from the thin client. The demo version appears to work acceptably, but there is a bit of a learning curve, it's not clear how well it would work for multiple simultaneous sessions, and it's not clear if it would be a good solution to apply to non-3D sessions. If possible, as with the hardware, we want to deploy a single software solution instead of a mishmash. If anyone has had experience managing a large installation of HP Remote Graphics, I would appreciate any feedback you can provide.

  • Debugging Tips for Skinning

    - by Christian David Straub
    Another guest post by Jeanne Waldman.If you are developing a skin for your Fusion Application in JDeveloper you should know these tips.   1. Firebug is your friend 2. Uncompress the css style classes 3. CHECK_FILE_MODIFICATION so that you see your skinning changes right away 4. View the generated CSS File   1. Firebug is your friend Install Firebug (http://getfirebug.com/layout) into Firefox and use it to view your rendered jspx page in the browser. You can select the HTML dom nodes on your page and you can see the css styles applied to each dom node.   2. Uncompress the css style classes By default the styleclasses that are rendered are compressed. You may see style classes like class="x10" and class="x2e". But in your skin css file you have styleclasses like: af|inputText::content or af|panelBox::header   It is easier for you to develop a skin and debug a skin with Firebug if you see the uncompressed styleclasses. To do this, a. open web.xml b. add   <context-param>     <param-name>org.apache.myfaces.trinidad.DISABLE_CONTENT_COMPRESSION</param-name>     <param-value>true</param-value>   </context-param> c. save d. restart the server and re-run your page.   3. CHECK_FILE_MODIFICATION so that you see your skinning changes right away   For performance sake the ADF Faces framework does not check if you skin .css file has changed on every render. But this is exactly what you want to happen when you are developing or debugging a skin. You want your changes to get noticed right away, without restarting the server.   To do this, a. open web.xml b. add   <context-param>     <description>If this parameter is true, there will be an automatic check of the modification date of your JSPs, and saved state will be discarded when JSP's change. It will also automatically check if your skinning css files have changed without you having to restart the server. This makes development easier, but adds overhead. For this reason this parameter should be set to false when your application is deployed.</description>     <param-name>org.apache.myfaces.trinidad.CHECK_FILE_MODIFICATION</param-name>     <param-value>false</param-value>   </context-param> c. save d. restart the server and re-run your page. e. from then on, you can change your skin's .css file, save it and refresh your page and you should see the changes right away   4. View the generated CSS File   There are different ways to view the generated CSS File which is your skin's css file merged in with all the skins it extends and processed and generated to the filesystem and linked to your generated html page. One way is to view it with Firebug. The problem with this approach is you might see something that is a little different than the actual css file because Firebug may do some extra processing. I like to view the generated css file by: Right click on your page in the browser

  • VisualStudio2010 Debugging - The process cannot access the file ... because it is being used by anot

    - by Richard Forss
    I'm unable to debug a WinForms C# application using the released version of Visual Studio 2010 Prof. I get the following error message after the second debugging run. Error 9 Unable to copy file "obj\x86\Debug\Arrowgrass Reports.exe" to "bin\Debug\Arrowgrass Reports.exe". The process cannot access the file 'bin\Debug\Arrowgrass Reports.exe' because it is being used by another process. I've tried a pre-build script to attempt to delete this file, but it's locked by Visual Studio. There are a few references to this on the net so it is a know problem. Does anyone have a hotfix or effective work-around?

  • Web service SSL handshake fails in production environment unless SSL debugging enabled

    - by JST
    Scenario: calling a client web service over SSL (https) with mutual SSL authentication. Different service endpoint URLs and certs (both keystore and truststore) for test vs. production environments. Both test and production environments run tomcat / JBoss clustered. Production environment has load balancing / BigIP, runs Blade and non-Blade machines. Truststore is set (using -Djavax.net.ssl.trustStore=value) at startup. Keystore is set using System.setProperty("javax.net.ssl.keyStore", "value") in Java code. Web service call made using Axis2. All works fine in test environment, but when we moved to production environment (6 servers), it appears certs are not being forwarded for the handshake. Here's what we've done: in test environment, handshake using test versions of certs has been working all along, with no ssl debugging enabled confirmed in test environment that handshake with client production endpoint succeeds (production certs, both ours and theirs, are fine) -- this was done using -Djavax.net.debug=handshake,ssl confirmed that the error condition occurs on all 6 production servers took one server out of the cluster, turned on ssl debugging for just that one (with a restart), hit it directly, handshake works! switched to a different server without the debugging turned on, handshake error condition occurs turned debugging on on that second server (with a restart), hit it directly, handshake works! From the evidence, it seems like somehow the debugging being enabled causes the certificates to be properly retrieved/conveyed, although that makes no sense! I wonder whether somehow the enabled debugging makes the system pay attention to the System.setProperty call, and ignore it otherwise. However, in local and test environments, handshake worked without debugging enabled. Do I maybe need to be setting keystore on server startup like I'm setting truststore? Have been avoiding that because the keystore will differ for each of our test environments (16 of them).

  • When Debugging in Xcode what does "out of scope" mean?

    - by Buffernet
    I'm in xcode debugging my iphone application. when i get to a break point and I roll over my object and properties of that object say "out of scope" instead of their respective values. Here's what I do: I have inited a view with nib name (initwithnibname). Then set the property of that view to the object that I want. I have placed the breakpoint in the viewwillappear method. I rollover my reference to the variable that was is my property. All properties in the object say "out of scope" Does anyone know why this is happening?

  • Is it possible to implement a GC.GetAliveInstancesOf<T>() (for use in debugging)?

    - by Omer Raviv
    Hi, I know this was answered before, but I'd like to pose a somewhat different question. Is there any conceivable way to implement GC.GetAliveInstancesOf(), that can be evaluated in Visual Studio Debug Watch window? Sasha Goldstein shows one solution in this article, but it requires every class you want to query inherit from a specific base class. I'll emphasize that I only want to use this method during debugging, so I don't care that the GC may change an object's address in memory during runtime. One idea might be to somehow harness the !dumpheap –type command of SOS, and do some magic trick to create a temporary variable and have it point out to the memory address printed by SOS. Does anyone have a solution that works?

  • Launch external application from C++ program and attach it to visual 2008 debugger while debugging host in WinAPI

    - by PiotrK
    Basically I have Host and Child program. I do not have sources for Child so I can't change anything in it. I want to launch Host from debugger, which at some point should launch Child program. I want to attach Child automatically for debugging session as well (so any breakpoints set in DLL sources loaded under Child process will hit). How to do this in Visual Studio 2008 C++ with standard WinAPI? I tried this: SHELLEXECUTEINFO sei = {0}; sei.cbSize = sizeof (SHELLEXECUTEINFO); sei.fMask = SEE_MASK_NOCLOSEPROCESS; sei.lpVerb = "open"; sei.lpFile = "Child.exe"; sei.lpParameters = "/Param"; sei.nShow = SW_SHOWNORMAL; if (ShellExecuteEx (&sei)) { WaitForSingleObject (sei.hProcess, INFINITE); } But this does not attach debugger for Child.exe

  • Why is the dictionary debug visualizer less useful in Visual Studio 2010 for Silverlight debugging?

    - by Kevin
    I was debugging in Visual Studio 2010, which we just installed and trying to look at a dictionary in the quick watch window. I see Keys and Values, but drilling into those shows the Count and Non-Public members, Non-Public members continues the trail and I never see the values in the dictionary. I can run test.Take(10) and see the values, but why should I have to do that. I don't have VS 2008 installed anymore to compare, but it seems that I could debug a dictionary much easier. Why is it this way now? Is it just a setting I set somehow on my machine? Test code: Dictionary<string, string> test = new Dictionary<string, string>(); test.Add("a", "b"); EDIT: I've just tried the same debug in a Console app and it works as expected. The other project is a Silverlight 4 application, why are they different? Console Debug Screen Shot Silverlight 4 Debug Screen Shot:

  • Screen recorder for tracking back your steps while debugging?

    - by hstoerr
    I am wondering whether there is a screen recorder that is usable for checking what exactly you did a couple of minutes ago while debugging, or just checking what value for a variable was displayed the last time you hit that breakpoint etc. (Of course this latter question would be something terrific for an IDE to implement, but I've never seen something like that so far. :-) For this you would need a screen recorder that could record all day and preferably automatically delete the recording the recording that is, say, older than an hour. Probably the recording format should be something that is good for screen recording instead of natural scenes. Do you know a screen recorder like that or at least one that comes close?
