Bug 1304815 - rearrange Rust crate structure for newer Rust releases; r=ted.mielczarek In our current Rust world, we have the following dependency structure: xul.so --------------------------+ | xul-gtest.so -+--> xul.a --------+-> gkrust | +--> gkrust-gtest This structure results in link errors with multiply-defined symbols between gkrust-gtest and gkrust with newer Rust releases when linking xul-gtest.so. So we have to do something different. Our new structure is: xul.so --------------------------+ | xul-gtest.so -+--> xul.a --------+-> gkrust --+-> gkrust-shared | | +--> gkrust-gtest --------------+ and we enforce that a given shared library can only have at most one Rust library that it depends on. Said Rust library is assumed to include all significant Rust dependencies of the dependent static libraries as well. (In the above structure, gkrust is simply a wrapper around gkrust-shared, so gkrust-gtest doesn't have to include gkrust as a dependency.)

# Available mustache parameters (see the mozilla-taskcluster source):
# - owner:          push user (email address)
# - source:         URL of this YAML file
# - url:            repository URL
# - project:        alias for the destination repository (basename of
#                   the repo url)
# - level:          SCM level of the destination repository

# - revision:       (short) hg revision of the head of the push
# - revision_hash:  (long) hg revision of the head of the push
# - comment:        comment of the push
# - pushlog_id:     id in the pushlog table of the repository
# and functions:
# - as_slugid:      convert a label into a slugId
# - from_now:       generate a timestamp at a fixed offset from now

# The resulting tasks' taskGroupId will be equal to the taskId of the first
# task listed here, which should be the decision task.  This gives other tools
# an easy way to determine the ID of the decision task that created a
# particular group.
