+# Script to bootstrap the 'wheel' wheel from deps.pst. You only need to run

Consider doing a script path discovery and constructing paths from that. This
would allow someone to run the script in another directory and still have it
work.

Alternatively you could assert "$0 == ./bootstrap_wheel_wheel.sh".

Done.

+./bootstrap.py --env_path BUILD_ENV
+
+. ./BUILD_ENV/bin/activate
+
+read -r -d '' PROG <<EOF

Consider exporting this to a "bootstrap_wheel_wheel_pre.py" script and just
running it. This would be pylintable and (IMO) cleaner.

[iannucci, 2014/07/11 02:14:46]

meh. there's already too many files here. Having this script self-contained is
more important, imo.

+import bootstrap
+print bootstrap.read_deps('deps.pst')['wheel']['gs']
+EOF
+SHA=$(echo "$PROG" | python -)

[dnj, 2014/07/10 16:06:18]

Either set "-e" (errexit) or explicitly check the return value.

[iannucci, 2014/07/11 02:14:46]

Done.

+pip install wheel "https://storage.googleapis.com/chrome-python-wheelhouse/sources/$SHA"
+
+rm -rf wheelhouse

Surround this w/ a directory check and maybe print a notice or something that
you're deleting user files.

[iannucci, 2014/07/11 02:14:45]

wheelhouse is only used by these scripts for building. If the user puts stuff in
there... um... ??

+mkdir wheelhouse
+
+python - <<EOF

[dnj, 2014/07/10 16:06:18]

Consider exporting this to a "bootstrap_wheel_wheel_post.py" script and just
running it. This would be pylintable and (IMO) cleaner.

[iannucci, 2014/07/11 02:14:45]

Acknowledged.
