NOTE: recipe llvm3.3-3.3-r0: task do_unpack: Failed
ERROR: Task (/home/jenkins/oe/world/shr-core/meta-openembedded/meta-oe/recipes-core/llvm/llvm3.3_3.3.bb:do_unpack) failed with exit code '1'Maybe I don't have the latest version of this patch (I'm not using your poky-contrib branch yet), but it should fail with nicer message when git log fails for whatever reason.
Conditionally set some environment variables in order to achieve
improved binary reproducibility. Providing BUILD_REPRODUCIBLE_BINARIES is
set to "1", we set the following environment variables:
export PYTHONHASHSEED=0
export PERL_HASH_SEED=0
export TZ="UTC"
We also export and set SOURCE_DATE_EPOCH. The value for this variable
is obtained after source code for a recipe has been unpacked, but before it is
patched. If the code comes from a GIT repo, we get the timestamp from the top
commit. (This usually corresponds to the mktime of "changelog".)
Otherwise we go through all files and get the timestamp from the youngest
one. We create a timestamp for each recipe. The timestamp is stored in the file
'src_date_epoch.txt'. Later on, each task reads this file and sets SOURCE_DATE_EPOCH
based on the value found in the file.
