Hardware for The Build Lab

by scmgalaxy KBuild Management & ToolsLeave a Comment on Hardware for The Build Lab

The build lab should include some high-end hardware for building the applications. Because the entire team depends on the results of a build, the high-end computers ensure that the build is completed as quickly as possible. Furthermore, you can use high-speed network equipment to push bits around from source control to build machines to release servers.

At a minimum, the build lab should have four machines:

  • Server that contains the Source Code Control program— This is your product. Do you really want this server residing someplace where you have little control over this box?
  • Debug build machine for the mainline builds— If you don’t separate your debug and release machines, you will accidentally ship debug binaries, which is not a good thing.
  • Release build machine for the mainline builds— This is a “golden goose” that turns out the “gold eggs” of your company or group. Treasure this machine like a princess, and guard it like all the king’s fortunes.
  • Internal release share server— This is one more piece of hardware that stores the “bread and butter” of the group or company. Don’t give up control of this hardware to anyone unless your IT department reports through your development group.

Hardware Requirements

Each machine in the preceding list should meet the following requirements:

  • Number of processors— This depends on the build tool you use. One is usually sufficient, because few build tools really take advantage of multiple processors.
  • Processor speed— The lab budget dictates this, but the faster the processor, the better it is.
  • Amount of installed RAM— Max out the machine. RAM is relatively cheap these days, especially when you consider the performance increase you get. Increasing the RAM is usually the first upgrade done when trying to improve the performance of any computer.
  • Number of hard drives— A minimum of two drives (or partitions) is preferred:
    • Drive 1 (C:) is for the operating system and installed applications.
    • Drive 2 (D:) is for building binaries, release shares, or the source database; the minimum space required is roughly ten times the space needed to build your application.
    • The split partitions are good because if you ever need to format or blow away a drive due to corruption, only part of the project will be affected. The recovery is much faster and easier.
  • Hard drive type— This is most likely SCSI, but it could be IDE.
  • Number of power supplies— If you purchase server class hardware (pizza boxes) that belong in racks, you need to consider how many power supplies to order.
  • Motherboard BIOS version— This does make a difference. Make sure you note what is being used and standardize on it.

Tag SVN “Nightly” Builds with CruiseControl.Net

by scmgalaxy KOther build ToolsLeave a Comment on Tag SVN “Nightly” Builds with CruiseControl.Net

rajeshkumar created the topic: Tag SVN “Nightly” Builds with CruiseControl.Net
How would I do a nightly or other scheduled build for CruiseControl.NET without having a duplicate project?

In my current config, every 60 seconds, I am checking out the trunk using Subversion, running MSBuild, then either NUnit or MSTest.

I would like to commit back to SVN as a tag, but I don’t want it on every successful build. I want it to make a nightly build or some other set schedule. To me, it seems a bit tedious to have two CruiseControl.Net projects with basically the same options. What is the best way to handle that?

As a bonus, I would like it to build as a release build and commit the binaries in the same tag.

Rajesh Kumar

rajeshkumar replied the topic: Re:Tag SVN “Nightly” Builds with CruiseControl.Net
i’ll tell you how we use ccnet (and we’re quite happy with it that way).

we’ve got 20 projects on the build server and several release branches of previous versions. we only start builds on demand using the cctray application. so after a developer is done implementing a feature, he clicks the “force build” button and ccnet starts to do its thing (build, test, tag, copy build output to a network drive, notify other devs,…).

the advantage is that devs can decide when to start a build. projects that haven’t changed aren’t built. projects with work in progress can be built several commits later, only when a developer thinks that he needs a build.

one idea that comes to mind for starting nightly builds would be to use ccnet’s remoting interface (which is also used by cctray), connect it to the ccnet instance and call the force-build-method at midnight.

concerning “committing binaries to the same tag”:

there is a problem in ccnet that causes it to sometimes tag a revision from the trunk and sometimes to tag the working copy. it does this depending on if there were changes since the last build (in which case it tags the revision from the trunk), or if there were no changes since the last build (in which case it tags the working copy).

this is pretty annoying because you never know what will be committed – in the first case your binaries won’t get committed, in the second case they will.

we have actually patched ccnet ourselves to make it always commit the working copy so we get deterministic behaviour. i have once submitted the patch but it never made it in…

scmuser replied the topic: Re:New Setup issues of CruseControl
I’m using Cruisecontrol 2.6.2 and I’m having problems with the JMX Control Panel.

First off, the URL for the Control Panel contains the hostname of the computer, which can’t be resolved over the network. I have tried setting the jmxhost parameter in the web.xml file to its IP adress, but it doesn’t work; it still uses the host name. As a workaround I’ve now entered the host name and the corresponding IP adress in my Hosts file, but I don’t want to do that for every computer, so is there a way to do this within cruisecontrol?

With the above workaround the host name can be resolved, but all that I get when I click the button for the control panel is an XML file:

“There is no/ style /i/nformation/ connected to this /XML file/. Subsequent the /Tree/-/View/ of the //document// is /shown/.”

….

Does anybody know how to fix this? Thanks.

Msbuild slower than devenv

by scmgalaxy KOther build ToolsLeave a Comment on Msbuild slower than devenv

scmuser created the topic: msbuild slower than devenv
Hi, I’m experiencing performance inconsistencies with regards to build duration when building a VS2008 solution file with either devenv or msbuild from command line.

My solution contains both C# and C++ projects, and I have these results:

devenv.exe (either command line or within the ide): 7 minutes msbuild.exe: 14 minutes

I tried tuning the msbuild switches passing /maxcpucount and /p:VCBuildAdditionalOptions=m# but with no luck so far.

Any idea?

scmuser replied the topic: Re:msbuild slower than devenv
what is the full msbuild command you are running?

As a side point, have you got the build output turned down to Quiet or Minimal? That reduces build time a little…

7 minutes to build in the IDE!! Personally I’d go insane, debugging must be a nightmare
