  • Push TFS 2008 code to remote VSS over VPN?

    - by drovani
    We have a local Team Foundation Server 2008 that we keep our code under version control. However, we also have a paranoid client that has their own Visual Source Safe installation that wants us to keep a running copy of the code on their server as well. As such, I'm hoping there is a way I can just do a nightly push from our TFS repository to their VSS repository. I'm not concerned about keeping each changeset on TFS as a different changeset on the VSS, just a once-nightly push that creates a new changeset on the VSS and uploads the latest changeset from TFS. I guess the first part is if it is even possible for TFS to push an update to VSS. I've noticed that most replies to this question have been something to the tune of "don't do it", but I can't find anything that specifically states that it cannot be done. The second part would then be automating the process by having the TFS server connect to the client's VPN, then push the code changes. I have full control over the TFS server and I can customize the VSS install, if there are settings that need changing, but I'm limited on what I can do about settings on either firewall or server specific settings on the client's VSS server.

  • An error saying unidentifed function "push", "pop", and"display" occurs, what should i add to fix i

  • What is Perl doing with this argument to push in this case?

    - by Morinar
    I just saw some code in our code base (and it's OLD code, as in Perl 3 or Perl 4 days) that looks like this (I'm simplifying greatly): my @array; push( array, $some_scalar ); Notice that the array in the push() doesn't have an @. I would assume that the code behind push knows that the first argument is supposed to be array so grabs the array from the array typeglob. Is that more or less it? If Perl is able to do that without problem, why would you need to include the @ at all?

  • How do I write Push and Pop in Scheme?

    - by kunjaan
    Right now I have (define (push x a-list) (set! a-list (cons a-list x))) (define (pop a-list) (let ((result (first a-list))) (set! a-list (rest a-list)) result)) But I get this result: Welcome to DrScheme, version 4.2 [3m]. Language: Module; memory limit: 256 megabytes. > (define my-list (list 1 2 3)) > (push 4 my-list) > my-list (1 2 3) > (pop my-list) 1 > my-list (1 2 3) What am I doing wrong? Is there a better way to write push so that the element is added at the end and pop so that the element gets deleted from the first?

  • Google analytics iframe code measuring visitor as two visitors

    - by Maarten
    I'm trying to measure visitors in an iframe and the site containing the iframe. What I would like is that visitors clicks in the iframe are seen being from the same visitor as the containing site, but somehow it is seen as two seperate visitors. I followed examples from http://www.blastam.com/blog/index.php/2011/02/google-analytics-cross-domain-tracking/, trimmed down to an even simpler version based on the comments about setDomainName not being needed anymore but with setDomainName I get the same result: a click on a page and a click on the iframe is seen as 2 clicks by 2 seperate visitors. This is the code in my iframe if (_gaq && gaAccount.length > 0){ _gaq.push(['_setAccount', gaAccount]); _gaq.push(['_setAllowLinker', true]); //_gaq.push(['_setDomainName', 'none']); _gaq.push(['_trackPageview', 'mytestcountername']); } And this is the code in the containing page: <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-9605474-4']); _gaq.push(['_setAllowLinker', true]); //_gaq.push(['_setDomainName', '.domain.nl']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); </script>

  • How to push changes from Test server to Live server?

    - by anonymous
    As a beginner, I finally noticed the issue with making changes to the live server I've been working on, now that I have a couple users on it, since I bring it down so often. I created an EC2 image of my live server and set up a separate instance on EC2, so now I have 2 EC2 instances, Stage and Production. I set up GitHub and push changes to stage and test my code there, and when it's all done and working, I push it to the production branch, and everything is good. And there is a slight issue here since I name my files config_stage.js and config_production.js and set up .gitignore on each server, and in my code, I would have it read the ENV flags and set up the appropriate configs, is this the correct approach? And my main question is: how do you keep track of non-code changes to the server? For example, I installed HAProxy, Stunnel, Redis, MongoDB and several other things onto the Stage server for testing and now that it's all working and good, how do I deploy them to production? Right now, I'm just keeping track of everything I installed and copying configuration files over, which is very tedious and I'm afraid I may have missed a step somewhere. Is there a better way to port these changes over from my test server to my live server?

  • Git clone/push/pull - where's that username comes from?

    - by Kuroki Kaze
    I've set up gitosis and able to pull/push through ssh. Gitosis is installed on Debian Lenny server, I'm using git from windows machine (msysgit). The strange thing, if I enable loglevel = DEBUG in gitosis.conf, I see something like this when doing any actions with gitosis server: D:\Kaze\source\test-project>git pull origin master DEBUG:gitosis.serve.main:Got command "git-upload-pack 'test_project.git'" DEBUG:gitosis.access.haveAccess:Access check for '[email protected]' as 'writable' on 'test_project.git'... DEBUG:gitosis.access.haveAccess:Stripping .git suffix from 'test_project.git', new value 'test_project' DEBUG:gitosis.group.getMembership:found '[email protected]' in 'test' DEBUG:gitosis.access.haveAccess:Access ok for '[email protected]' as 'writable' on 'test_project' DEBUG:gitosis.access.haveAccess:Using prefix 'repositories' for 'test_project' DEBUG:gitosis.serve.main:Serving git-upload-pack 'repositories/test_project.git' From 192.168.175.128:test_project * branch master -> FETCH_HEAD Already up-to-date. Question is: why am I *[email protected]? This email is in global user.email config variable, too. Yesterday, when the gitosis was installed, it seen me as kaze@KAZE, this is the name under which I was added to gitosis-admin group (and it worked). But today git (or gitosis) started to see me as [email protected]. This is true for all repositories I push or clone. I had to add this address to gitosis.conf directly on server to be able to edit configs again (it worked). There is 2 public keys in keydir: [email protected] and [email protected], their content is identical and they have kaze@KAZE at end. Origin URL looks like git@lennyserver:test_project. Now, the question is - why Git (or gitosis) suddenly decided to call me by email instead of name@machinename? I've changed a couple things trying to set up Gitosis (updated git on server to 1.6.0 for example), but maybe I broke something in my local git installation?

  • Push or Pull Input Data In the Game Logic?

    - by Qua
    In the process of preparing my game for networking I'm adding a layer of seperation between the physical input (mouse/keyboard) and the actual game "engine"/logic. All input that has any relation to the game logic is wrapped inside action objects such as BuildBuildingAction. I was thinking of having an action processing layer that would determine what to do with the input. This layer could then be set up to either just pass the actions locally to the game engine or send it via sockets to the network server depending on whether the game was single- or multiplayer. In network games it would make sense that the player's actions should be sent to the server, but should the game logic be pulling (polling?) the data through some sort of interface or should the action processing layer be adding the actions to an input queue in the game logic code?

  • Is it OK to push my code to GitHub while it is still in early development?

    - by marco-fiset
    I have some projects that are in a very early development state. They are nowhere nearing completion but I do host them (as public repos) on GitHub because: I have multiple computers and I want access to my code everywhere I want a backup for my code I want it to be easy if someone wants to collaborate in some way I use GitHub Issues as a poor man's project management software Is it OK to publish a project on GitHub even when it is very early in the development? I am a bit concerned about someone to come by and say OMG this is total BS, this code is so bad! while looking at unpolished/still in development/not tested code. What are your practices when you start new public projects? Do you wait until you have something substantial to show or you create a bare repo directly on GitHub and start from there? I used GitHub throughout this post but this applies to every code hosting service out there.

  • Does Ubuntu ever push new versions of GCC into the package repository between releases?

    - by Lex Fridman
    Current version of GCC in Ubuntu 11.04 is 4.5.2. For certain C++0x features, I need GCC version 4.6, but would like to avoid compiling from source. Is there hope that Ubuntu will update GCC in the package repository before the next release in October (11.10). This question asks a similar thing except for an earlier version of Ubuntu and GCC. A second part of the question, if the answer is "no" to the first, then can I hope to see it appear in Ubuntu's unstable repository?

  • Can I push my working directory without first committing it?

    - by Derek
    I have my web server set up as a remote git repo, so I can type "git push staging" and my last commit goes live on the server. I used this tutorial to set this up. A lot of the time, I'm testing a new feature, and I want to test several iterations of it on the staging server, before it's ready to quality as a commit. Is there a way to push my working directory to the server without having to commit it first?

  • How to get push notifications for email on iPhone?

    - by Josh Stodola
    Is it possible to receive a standard push notification on the iPhone (like receiving a text message) when a new email is received? Or even if it was a every ~5 minutes type of thing, that would also be acceptable. How can this be achieved? Currently I have to open the mail app to check for new messages, and I would much rather be notified.

  • How can you avoid being asked to enter your BitBucket password when you push to BitBucket wiki?

    - by CalumJEadie
    I'm not sure if everyone experiences this - when I edit a BitBucket wiki locally (through a git repository) I have to enter my BitBucket password for every pull and push. Is there any way around this? I have ssh correctly configured to use a key that is unlocked by gnome-keyring. Pushing to the code repository for my project in BitBucket works fine - I do not need to enter either by BitBucket or ssh key password.

  • How to push a new feature to a central Mercurial repo?

    - by Sly
    I'm assigned the development of a feature for a project. I'm going to work on that feature for several days over a period of a few weeks. I'll clone the central repo. Then I'm going to work locally for 3 weeks. I'll commit my progress to my repo several times during that process. When I'm done, I'm going to pull/merge/commit before I push. What is the right way push my feature as a single changeset to the central repo? I don't want to push 14 "work in progress" changesets and 1 "merged" changeset to the central repo. I want other collaborators on the project to see only one changeset with a significant commit message (such as "Implemented feature ABC"). I'm new to Mercurial and DVCS so don't hesitate to provide guidance if you think I'm not approaching that the right way. <My own answer> So far I came up with a way of reducing 15 changeset to 2 changeset. Suppose changesets 10 to 24 are "work in progress" changesets. I can 'hg collapse -r 10:24 -m "Implemented feature ABC"' (14 changesets collapsed into 1). Then, I must 'hg pull' + 'hg merge' + 'hg commit -m "Merged with most recent changes"'. But now I'm stuck with 2 changesets. I can no longer 'hg collapse', because pull/merge/commit broke my changeset sequence. Of course 2 changesets is better then 15 but still, I'd rather have 1 changeset. </My own answer>

  • How to correctly track the analytics when using iframe

Inside the iframe we setup this analytics code <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-1301114-2']); _gaq.push(['_setDomainName', 'reservations.synxis.com']); _gaq.push(['_setAllowLinker', true]); _gaq.push(['_trackPageview', 'AvailabilityResults']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ?

The first one is a direct traffic and the other one is a cpc. How come that they have different source? I was expecting that both of them is using a direct traffic.

  • Offlineimap -- push changes to all folders; only pull from INBOX folder

    - by g33kz0r
    I would like to be able to set up offlineimap to do the following Sync Remote/INBOX - Local Sync Local/Maildirs/* - Remote Possible? The use case here is: I download all new mail from my remote IMAP INBOX folder with offlineimap. offlineimap's posthook command calls a custom python script which does junk filtering, then sorts and categorizes my mail in the local INBOX folder to various local maildirs based on sender, etc. I read my mail with mutt and perhaps do some more categorization. ? Step 4 is what I'm after. I want offlineimap to push my local changes (categorization, filtering, deletion in the case of spam) back to the various folders on the imap server, but as you can see, there's no need for me to be pulling any changes from folders other than Remote/INBOX, as no changes happen on the IMAP server itself. I hope that's a clear explanation of the problem.

  • How do I scale EC2 and push out code / data to my instances?

    - by chris
    Unfortunately I only have a limited knowledge of server architecture, I come from a development background. I am looking to ensure my new app can scale properly using EC2. I currently have a T1.micro for development running Windows with SQL server 2008. The system allows students to come to our site to search for a mentor, update their profile with pictures and employment history etc. Roughly the same sort of work as a LinkedIn profile. I need this to be able to scale very quickly without wasted resources. I understand the following is important. Separation of data, application etc. I will achieve this I think by hosting images using S3, Database instance via RDS and upgrade the EC2 instance. My main question is: How do I push data / code out to multiple ec2 / RDS instances seamlessly?

  • Why do I get this error when I try to push my SQLite3 to Postgresql (via Taps) on Cedar Stack?

  • What should I do or don't do to avoid Delphi "push dword" bug.

    - by Maksee
    I found that Delphi 5 generates invalid assembly code in specific cases. I can't understand in what cases in general. The example below produces access violation since a very strange optimization occurs. For a byte in a record or array Delphi generates push dword [...], pop ebx, mov .., bl that works correctly if there are data after this byte (we need at least three to push dword correctly), but fails if the data is inaccessible. I emulated the strict boundaries here with win32 Virtual* functions Specifically the error occurs when the last byte from the block accessed inside FeedBytesToClass procedure. And if I try to change something like using data array instead of object property of remove actionFlag variable, Delphi generates correct assembly instructions. const BlockSize = 4096; type TSomeClass = class private fBytes: PByteArray; public property Bytes: PByteArray read fBytes; constructor Create; destructor Destroy;override; end; constructor TSomeClass.Create; begin inherited Create; GetMem(fBytes, BlockSize); end; destructor TSomeClass.Destroy; begin FreeMem(fBytes); inherited; end; procedure FeedBytesToClass(SrcDataBytes: PByteArray; Count: integer); var j: integer; Ofs: integer; actionFlag: boolean; AClass: TSomeClass; begin AClass:=TSomeClass.Create; try actionFlag:=true; for j:=0 to Count-1 do begin Ofs:=j; if actionFlag then begin AClass.Bytes[Ofs]:=SrcDataBytes[j]; end; end; finally AClass.Free; end; end; procedure TForm31.Button1Click(Sender: TObject); var SrcDataBytes: PByteArray; begin SrcDataBytes:=VirtualAlloc(Nil, BlockSize, MEM_COMMIT, PAGE_READWRITE); try if VirtualLock(SrcDataBytes, BlockSize) then try FeedBytesToClass(SrcDataBytes, BlockSize); finally VirtualUnLock(SrcDataBytes, BlockSize); end; finally VirtualFree(SrcDataBytes, MEM_DECOMMIT, BlockSize); end; end; Initially the error occured when I used access to RGB data of bitmap bits, but the code there is too complex so I narrowed it to this fragment. So the question is what is here so specific that makes Delphi produce push,pop,mov optimization. I need to know this in order to avoid such side effects in general.

  • In UISplitViewController rootView/masterView to tell detailView to push a viewcontroller ?

    - by arash13
    This is almost a follow up of my last question. Now i have a splitview with a rootview / leftview that has a table and detailview / rightView that has some view controller pushed into it's navigationcontroller. So this is what i want to achieve: When i tap on a tablerow on my rootView , i want my detail view to push a viewController associated with that row... any ideas ? I also tried making a protocol on my tableviewcontroller and have it implemented in detailview controller .. but i dont know how to call it, is it [self performselector:.... ? case 1:{switch ([indexPath row]) { case 0:{[_detailViewController.navigationController pushViewController:_s2d animated:YES]; // just trying to push it from here but didnt work }break; case 1:{ [_detailViewController loadEqViewController]; // this one is an instance method in detailview it is being called but nothing happends }break; }}break;
