Upstream envoyproxy/envoy-wasm. #12546
Conversation
|
The Linux-x64 release seems to be a flake. I don't know that this code has ever been tested on Windows or arm64. Any suggestions on how to debug these things locally and/or disable the Wasm extensions for these environments? |
|
@jplevyak we can skip arm / windows, just modify build_setup / do_ci script to add bazel flags. |
|
@jplevyak how far does this get us to Wasm upstreaming? Is this mission complete? Would be good to document the support status after this PR in the commit message and version history. |

The api/ tree is for xDS APIs, why is there Wasm docs and build files here?

This is all going to be removed. Pending envoyproxy/envoy-wasm#613 which I will merge in here and ping this thread.

@lizan thoughts on relationship to https://github.com/envoyproxy/envoy/blob/master/tools/clang_tools/support/BUILD.prebuilt?
|
@htuch with this we will be 95% complete. There are a couple things which are still under development by interns and there is one thing that istio needs, but for all intents and purposes this will be enough for most users. |
Which flags do you mean? I don't think we have a flag to remove Wasm support i.e. we have --define wasm=enabled and --define wsam=wavm, but I don't think we have --define wasm=none. |

Please toggle the default value of whether wasm is compiled here, so it is tested in CI:

@lizan I have made v8 support optional. We now need to add --define wasm=enabled to make it enabled. Which C builds should it default to being enabled? |
In general, most/all things default to enabled/included. Also, please the settings here: https://github.com/envoyproxy/envoy/blob/master/bazel/README.md#disabling-optional-features |

Wavm has a cmake build system, why can't we build it under rules_foreign_cc rather than this handcrafted blob thing?

WAVM is built using rules_foreign_cc, this here is a BUILD file for Proxy-Wasm C++ host implementation, which optionally includes WAVM support.

Is there any possibility here of not checking in this long glob file?

Do you want all the files called out separately for each case? It will be longer, but perhaps that is OK?

It looks like you folks are contributors to https://github.com/proxy-wasm/proxy-wasm-cpp-host. Can you add some Bazel BUILD files there?
So what's the default that we want to implement? V8 enabled by default, WAVM (only?) enabled with |
I don't know the tradeoffs or considerations for V8 vs WAVM. Someone else can chime on that. My request is just that there be a way to not compile either one in (which it looks like is now provided), and that we try to test as many variations as possible in CI. |
