  • TFS Folders - Getting them to work like Subversion "Trunk/Tags/Branches"

    - by Sam Schutte
    I recently started using Team Foundation Server, and am having some trouble getting it to work the way I want it to. I've used Subversion for a couple years now, and love the way it works. I always set up three folders under each project, Trunk, Tags, and Branches. When I'm working on a project, all my code lives under a folder called "C:\dev\projectname". This "projectname" folder can be made to point to either trunk, or any of the branches or tags using Subversion (with the switch command). Now that I'm using TFS (my client's system), I'd like things to work the same way. I created a "Trunk" folder with my project in it, and mapped "Project/Trunk/Website" to "c:\dev\Website". Now, I want to make a release under the "tags" folder (located in "Project/Tags/Version 1.0/Website", and TFS is giving me the following error when I execute the branch command: "No appropriate mapping exists for $Project/tags/Version 1.0/Website" From what I can find on the internet, TFS expects you to have a mapping to your hard drive at the root of the project (the "Project" folder in my case), and then have all the source code that lives in trunk, tags and branches all pulled down to your hard drive. This sucks because it requires way too much stuff on your hard drive, and even worse, when you are working in a solution in Visual Studio, you won't be able to pull down "Version 2.0" and have all your project references to other projects work, because they'll all be pointing to "trunk" folders under the main folder, not just the main folder itself. What I want to do is have the root "Project/Website" folder on my hard drive, and be able to have it point to (mapped to) either tags, branches, or trunk, depending on what i'm doing, without having to screw around with fixing Visual Studio project references. Ideas?

  • Why does Git.pm on cygwin complain about 'Out of memory during "large" request?

    - by Charles Ma
    Hi, I'm getting this error while doing a git svn rebase in cygwin Out of memory during "large" request for 268439552 bytes, total sbrk() is 140652544 bytes at /usr/lib/perl5/site_perl/Git.pm line 898, <GEN1> line 3. 268439552 is 256MB. Cygwin's maxium memory size is set to 1024MB so I'm guessing that it has a different maximum memory size for perl? How can I increase the maximum memory size that perl programs can use? update: This is where the error occurs (in Git.pm): while (1) { my $bytesLeft = $size - $bytesRead; last unless $bytesLeft; my $bytesToRead = $bytesLeft < 1024 ? $bytesLeft : 1024; my $read = read($in, $blob, $bytesToRead, $bytesRead); //line 898 unless (defined($read)) { $self->_close_cat_blob(); throw Error::Simple("in pipe went bad"); } $bytesRead += $read; } I've added a print before line 898 to print out $bytesToRead and $bytesRead and the result was 1024 for $bytesToRead, and 134220800 for $bytesRead, so it's reading 1024 bytes at a time and it has already read 128MB. Perl's 'read' function must be out of memory and is trying to request for double it's memory size...is there a way to specify how much memory to request? or is that implementation dependent? UPDATE2: While testing memory allocation in cygwin: This C program's output was 1536MB int main() { unsigned int bit=0x40000000, sum=0; char *x; while (bit > 4096) { x = malloc(bit); if (x) sum += bit; bit >>= 1; } printf("%08x bytes (%.1fMb)\n", sum, sum/1024.0/1024.0); return 0; } While this perl program crashed if the file size is greater than 384MB (but succeeded if the file size was less). open(F, "<400") or die("can't read\n"); $size = -s "400"; $read = read(F, $s, $size); The error is similar Out of memory during "large" request for 536875008 bytes, total sbrk() is 217088 bytes at mem.pl line 6.

  • Django + Virtualenv: manage.py commands fail with ImportError of project name.

    - by Bartek
    This is blowing my mind because it's probably an easy solution, but I can't figure out what could be causing this. So I have a new dev box and am setting everything up. I installed virtualenv, created a new environment for my project under ~/.virtualenvs/projectname Then, I cloned my project from github into my projects directory. Nothing fancy here. There are no .pyc files sitting around so it's a clean slate of code. Then, I activated my virtualenv and installed Django via pip. All looks good so far. Then, I run python manage.py syncdb within my project dir. This is where I get confused: ImportError: No module named projectname So I figured I may have had some references of projectname within my code. So I grep (ack, actually) through my code base and I find nothing of the sorts. So now I'm at a loss, given this environment why am I getting an ImportError on a module named projectname that isn't referenced anywhere in my code? I look forward to a solution .. thanks guys!

  • How should I detect unnecessary #include files in a large C++ project?

    - by shambolic
    I am working on a large C++ project in Visual Studio 2008, and there are a lot of files with unnecessary #include's. Sometimes the #include's are just artifacts and everything will compile fine with them removed, and in other cases classes could be forward declared and the #include could be moved to the .cpp file. Are there any good tools for detecting both of these cases?

  • How do I make lines scale when using GLOrtho?

    - by Mason Wheeler
    I'm using GLOrtho to set up a 2D view that I can render textures onto. It works really well, up until I try to zoom in on the image. If I pass half the width and half the height of the viewport to GLOrtho, I end up with all my textures displayed twice as big as normal, which is exactly what I expect. But then I try to draw a box around part of the image and it all falls apart. I call glBegin(GL_LINE_LOOP), place the four vertices, and call glEnd, and I expect to see the same thing I would see if I drew it at normal zoom level, doubled. Instead, I get lines that are all the right length, but they all come out one pixel wide, instead of two, and it looks really bad. What am I missing?

  • Version Control: multiple version hell, file synchronization

    - by SigTerm
    Hello. I would like to know how you normally deal with this situation: I have a set of utility functions. Say..5..10 files. And technically they are static library, cross-platform - SConscript/SConstruct plus Visual Studio project (not solution). Those utility functions are used in multiple small projects (15+, number increases over time). Each project has a copy of a few files or of an entire library, not a link into one central place. Sometimes project uses one file, two files, some use everything. Normally, utility functions are included as a copy of every file and SConscript/SConstruct or Visual Studio Project (depending on the situation). Each project has a separate git repository. Sometimes one project is derived from other, sometimes it isn't. You work on every one of them, in random order. There are no other people (to make things simpler) The problem arises when while working on one project you modify those utility function files. Because each project has a copy of file, this introduces new version, which leads to the mess when you try later (week later, for example) to guess which version has a most complete functionality (i.e. you added a function to a.cpp in one project, and added another function to a.cpp in another project, which created a version fork) How would you handle this situation to avoid "version hell"? One way I can think of is using symbolic links/hard links, but it isn't perfect - if you delete one central storage, it will all go to hell. And hard links won't work on dual-boot system (although symbolic links will). It looks like what I need is something like advanced git repository, where code for the project is stored in one local repository, but is synchronized with multiple external repositories. But I'm not sure how to do it or if it is possible to do this with git. So, what do you think?

  • What is the best way to organize directories within a large grails application?

    - by egervari
    What is the best way to organize directories within a large grails application? In a typical Spring application, we'd have myproject/domain/ and myproject/web/controllers and myproject/services Since grails puts these artifacts in their own directories... and then just uses the same base project package for everything, what is the best practice? Use the same sub package name for domain objects, controllers, services too? Ken

  • What are the reasons to use SQL Server instead of MySQL with a complex .Net project?

    - by cdeszaq
    We currently have a 10 year old nasty, spaghetti-code-style SQL Server database that we are soon looking to pretty much re-write from scratch as part of a re-write to a large web application. (The existing application will serve as the functional requirements for the next incarnation of the app) The new version will be developed in .Net, so a large portion of the application stack will be based on Microsoft technologies (Visual Studio will be used IIS will be the application server). One of the developers on the project has raised the possibility of switching to MySQL instead of SQL Server in order to save on cost for both the licence of the DB server, as well as the tools to design and manipulate the DB (such as the wonderfully free MySQL Workbench). What are the various pros and cons of using SQL Server vs. MySQL as the database for a complex .Net project? Price is one factor we have identified, both in terms of the DB server licence as well as tools to manipulate the DB, but what other factors come into play?

  • Can I version dotfiles within a project without merging their history into the main line?

    - by istrasci
    I'm sure this title is fairly obscure. I'm wondering if there is some way in git to tell it that you want a certain file to use different versions of a file when moving between branches, but to overall be .gitignored from the repository. Here's my scenario: I've got a Flash Builder project (for a Flex app) that I control with git. Flex apps in Flash Builder projects create three files: .actionScriptProperties, .flexProperties, and .project. These files contain lots of local file system references (source folders, output folders, etc.), so naturally we .gitignore them from our repo. Today, I wanted to use a new library in my project, so I made a separate git branch called lib, removed the old version of the library and put in the new one. Unfortunately, this Flex library information gets stored in one of those three dot files (not sure which offhand). So when I had to switch back to the first branch (master) earlier, I was getting compile errors because master was now linked to the new library (which basically negated why I made lib in the first place). So I'm wondering if there's any way for me to continue to .gitignore these files (so my other developers don't get them), but tell git that I want it to use some kind of local "branch version" so I can locally use different versions of the files for different branches.

  • Low cost way to host a large table yet keep the performance scalable?

    - by Leo Liang
    I have a growing table storing time series data, 500M entries now, and 200K new records every day. The total size is around 15GB for now. My clients are querying the table via a PHP script mostly, and the size of the result set is around 10K records (not very large). select * from T where timestamp > X and timestamp < Y and additionFilters And I want this operation cheap. Currently my table is hosting in Postgres 7, on a single 16G memory Box, and I would love to see some good suggestion for me to host this in low cost and also allow me to scale up for performance if needed. The table serves: 1. Query: 90% 2. Insert: 9.9% 2. Update: 0.1% <-- very rare.

  • How to scale JPEG images with a non-standard sampling factor in Java?

    - by HRJ
    I am using Java AWT for scaling a JPEG image, to create thumbnails. The code works fine when the image has a normal sampling factor ( 2x2,1x1,1x1 ) However, an image which has this sampling factor ( 1x1, 1x1, 1x1 ) creates problem when scaled. The colors get corrupted though the features are recognizable. The original and the thumbnail: The code I am using is roughly equivalent to: static BufferedImage awtScaleImage(BufferedImage image, int maxSize, int hint) { // We use AWT Image scaling because it has far superior quality // compared to JAI scaling. It also performs better (speed)! System.out.println("AWT Scaling image to: " + maxSize); int w = image.getWidth(); int h = image.getHeight(); float scaleFactor = 1.0f; if (w > h) scaleFactor = ((float) maxSize / (float) w); else scaleFactor = ((float) maxSize / (float) h); w = (int)(w * scaleFactor); h = (int)(h * scaleFactor); // since this code can run both headless and in a graphics context // we will just create a standard rgb image here and take the // performance hit in a non-compatible image format if any Image i = image.getScaledInstance(w, h, hint); image = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB); Graphics2D g = image.createGraphics(); g.drawImage(i, null, null); g.dispose(); i.flush(); return image; } (Code courtesy of this page ) Is there a better way to do this? Here's a test image with sampling factor of [ 1x1, 1x1, 1x1 ].

  • What are some best practices for making sure your .NET code will scale well?

    - by billmaya
    Last week I interviewed for a position at a TripleA MMORPG game company here in NE. I didn't get the job but one of the areas that came up during the interview was the about the scalability of the code that you write and how it should be considered early on in the design of your architecture and classes. Sadly to say I've never thought very much about the scalability of the .NET code that I've written (I work with single user desktop and mobile applications and our major concerns are usually with device memory and rates of data transmission). I'm interested in learning more about writing code that scales up well so it can handle a wide range of remote users in a client server environment, specifically MMORPGs. Are there any books, web sites, best practices, etc. that could get me started researching this topic?

  • How to extend a large website to an iPhone app?

    - by xoail
    I am trying to create an iPhone app for a large website (as big as amazon.com) and it involves using cookies and what not to get authenticated via the Apache intercepter and access the web services exposed by the main website. For that I am looking for strategies to go about developing it. I am new to iPhone development and I am mostly looking for some architectural guidance. Does anyone know how services like eBay and Amazon work seamlessly across the website and iPhone app?

  • How to process large block data visualization with Flex?

    - by hydra1983
    I know that's a big topic. However, it's better to know some general ideas to handle such problems. I have an application which requires Flex to render statistics data calculated instantly on the client side from a downloaded data set. The problems are: the data set is large and needs more than 10 seconds to be downloaded. there are some filters to control the statistics calculation algorithms. If user changes the filters, it would take a long time to recalculate the result and freeze the UI.

  • NHibernate One to One Foreign Key ON DELETE CASCADE

    - by xll
    I need to implement One-to-one association between Project and ProjecSettings using fluent NHibernate: public class ProjectMap : ClassMap<Project> { public ProjectMap() { Id(x => x.Id) .UniqueKey(MapUtils.Col<Project>(x => x.Id)) .GeneratedBy.HiLo("NHHiLoIdentity", "NextHiValue", "1000", string.Format("[EntityName] = '[{0}]'", MapUtils.Table<Project>())) .Not.Nullable(); HasOne(x => x.ProjectSettings) .PropertyRef(x => x.Project); } } public class ProjectSettingsMap : ClassMap<ProjectSettings> { public ProjectSettingsMap() { Id(x => x.Id) .UniqueKey(MapUtils.Col<ProjectSettings>(x => x.Id)) .GeneratedBy.HiLo("NHHiLoIdentity", "NextHiValue", "1000", string.Format("[EntityName] = '[{0}]'", MapUtils.Table<ProjectSettings>())); References(x => x.Project) .Column(MapUtils.Ref<ProjectSettings, Project>(p => p.Project, p => p.Id)) .Unique() .Not.Nullable(); } } This results in the following sql for Project Settings: CREATE TABLE ProjectSettings ( Id bigint PRIMARY KEY NOT NULL, Project_Project_Id bigint NOT NULL UNIQUE, /* Foreign keys */ FOREIGN KEY (Project_Project_Id) REFERENCES Project() ON DELETE NO ACTION ON UPDATE NO ACTION ); What I am trying to achieve is to have ON DELETE CASCADE for the FOREIGN KEY (Project_Project_Id), so that when the project is deleted through sql query, it's settings are deleted too. How can I achieve this ? EDIT: I know about Cascade.Delete() option, but it's not what I need. Is there any way to intercept the FK statement generation?
