This reduces the container size from 1.4 GB to 640 MB. 129 MB is
jessie, 489 MB jdk, and 22 MB grpc-java. When we swap from jessie to
stretch, we could swap to openjdk:8-jdk-slim-stretch which would make
the entire image 265 MB.
Python was never needed; it was added by mistake in 0589e533.
Pre-downloading gradle artifacts isn't helpful these days, because we
build on a clean machine. Git isn't needed as cp is sufficient. libapr1
has not been required by tcnative for a long time, and we even use
tcnative-boringssl-static since at least 1.0, which also doesn't need
it. The final cleanup is to remove source and downloaded artifacts when
done compiling.
All these changes need to go together to make sense
- changes to use new version of upb in bazel
- allowing includes in build target option
- script for generating c code (upb) for protos
- generated code for example protos
- adding changes for non-bazel builds
- change sanity tests to ignore the generated files.
* Use latest pylint in Python 3.7 (they dropped support for PY2)
* Make latest pylint happy
* Forced to upgrade to shellcheck 0.4.4
* Make shellcheck 0.4.4 happy
* Adopt reviewers' advice to reduce global disabled rules
using ccache when building under a docker image isn't useful when
building on kokoro as each build runs on a fresh VM.
Originally ccache builds were used to speed up jenkins builds,
now removing to guarantee build isolation and simplify stuff.
