Take a fresh 2.0 #20212 image and execute something like: ZnClient new signalProgress: true; url: 'http://zn.stfx.eu/zn/small.html'; downloadTo: FileSystem workingDirectory fullPath Bam! The second time, it works as expected.

Issue 6376: [Jenkis] test runs fails due to error loading CISupport http://code.google.com/p/pharo/issues/detail?id=6376

As we can't run tests, nothing will be integrated other than fixes that fix this.

Found it!

Very good! And yes, that looks very much like the problem... For the image itself: As we can't load anything, I will do a pre-build where the problem happend once and we start with that. Then we can add the fix to that. (not perfect but good enough) Marcus

Issue 6376: New ProcessSpecificVariables & Running Processes http://code.google.com/p/pharo/issues/detail?id=6376

It seems that Zinc has exposed a lurking bug with ProcessSpecificVariables. From issue 6376... If a process is already using a ProcessSpecificVariable, and another is added to the system, this new PSV is not added to the env instVar of those processes. When access to the new PSV is attempted, a subscript error is thrown.

To reproduce, evaluate: ZnClient new signalProgress: true; url: 'http://zn.stfx.eu/zn/small.html'; downloadTo: FileSystem workingDirectory fullPath

Process class>>allocatePSKey: adds the psv ZnSignalProgress to PSKeys. Later, when Process>psValueAt:put: is called, env is initialized if nil, but it's not nil (maybe because ZnConnectionTimeout has been used previously?). This is probably the first time we encountered two PSVs in the image at the same time, which flushed out the bug. In this case, env is not updated, and access is attempted to index 2, which doesn't exist.

This attached fileout resizes already-initialized envs if they need to be updated due to more PSVs having been added. It's ugly, but I want Igor to take a look before I clean it up to make sure we're on the right track.
