# Given a git source repo, generate a tarball from the desired branch, modify
|
|
# the spec file and upload it to lookaside cache if the tarball unpacks and
|
|
# gets patched cleanly.
|
|
#
|
|
# Usage:
|
|
#
|
|
# 1. Invoke the script as follows:
|
|
#
|
|
# ./sync-upstream.sh upstream-repo
|
|
#
|
|
# where upstream-repo is the path to the synced upstream git repo.
|
|
#
|
|
# 2. Watch the script run. If it proceeds to building the package, then
|
|
# everything seems good and you just need to test the build after it
|
|
# is complete. If it exits before the build (you'll know if you read
|
|
# the output of the script) then manual intervention is required to
|
|
# complete the sync. This will typically happen when a patch fails
|
|
# to apply on the new sources.
|
|
|
|

|
|
# another branch.
