[cross-project-issues-dev] Improving Hudson (was Why allowing Hudson to write to your downloads is a Bad Idea.)

Unfortunately it is not only argument sake... I think everybody understands the possibilities/benefits of a CI system because they've experienced it at their companies but the one available at Eclipse is hard to work with because of the restrictions imposed. Your initial suggestion of reducing the ability to move files around, which IMO is fundamental to a build system, is just causing all these moments of pain dealing with hudson at eclipse to resurface.

At a time where the foundation is thinking of providing a common build infrastructure in the context of the LTS initiative, it seems that this decisions / recommendations are being at odds with the overall goal of making it easy to build at Eclipse (and fuel the discussions of continuing building things being corporate firewalls: the infrastructure is hard to work with and can't be trusted (this is the conclusion someone would get looking at this thread)).

At this point I don't have a particular solution to offer for the given problem and instead I'm proposing to start list of the "freedoms" committers need to have to be able to successfully leverage the infrastructure put in place. So here it is:
- Need to request creation of a build job. 
you trust me to write code and commit it but not to create a job
- Difficulties to follow the typical workflows of deploying from Hudson (be it a file system, or a maven repo)
Btw, the cron approach may ends up partially copying repos. Also it does not anyone to control the complete end to end build from Hudson.
- Inability to get a stack dump from a slave when the test are the build is stuck

I never said anyone should do any of that. I never said you shouldn't trust the output of Hudson either.

I only suggested what is in the subject line of this email: allowing Hudson to write to your downloads is a Bad Idea.  And I explained why.

We simply got here for argument's sake.

So... suddenly our builds will take days for someone to build it, grab it, test it, and promote it, and even then it's highly unlikely that they'd catch anything that a somewhat competent attacker would throw at us. There's no way anyone is going to take on this overhead.

      At no point have I seen anyone answer this question:
          What can be done manually to determine if what's produced by Hudson is compromised or not?
Off the top of my head:

1. run a build on a remote system and compare the pre-signed binaries.

2. run a past build and compare today's binaries with those in the past.

3. run a build and examine the execution trace.

4. run a build, run the executable and examine network output for unknown activity.

      I also have to question whether this change during the SR1 shutdown phase is appropriate timing...
Go download the latest Linux Kernel from and tell me if there is ever a more appropriate time than 'now' to discuss security.

          I'll come back to something Dave Carver mentioned yesterday. If we don't trust Hudson, then we shouldn't be using it, or at least should be wrapping it up in tighter security, like a VPN for example. If someone is going to do something malicious and they're smart, you're likely not going to be able to discover it. You have to cut it at the source.

          And is this not an issue other Hudson/Jenkins users have run into? What are they doing for security. Or do they trust Hudson as much as they do ssh.
