Graft Glob Bug #145

Open jhclark opened 11 years ago

jhclark commented 11 years ago

Graft globs that are routed to a parent task via a global variable do not work. The following should have only 1 realization for "broken" but instead has 2:

task feeder < in=(TestSet: x=/dev/null y=/dev/null) > out {}

task works1 < in=$out@feeder[TestSet:*] {}

global {
  file=(TestSet: x=/dev/null y=/dev/null)
}
task works2 < in=$file[TestSet:*] {}

global {
  var=$out@feeder
}
task broken < in=$var[TestSet:*] {}

Output:

RUN: /home/jhclark/software/ducttape/syntax/issues/shouldSucceed/./works2/Baseline.baseline (Baseline.baseline)
RUN: /home/jhclark/software/ducttape/syntax/issues/shouldSucceed/./feeder/Baseline.baseline (TestSet.x)

To be clear, this bug is that because "broken" uses a glob, and introduces no other branch points, it should have exactly one realization.
