@htuch - quick summary

there is a remaining issue on what to do with the validation checks that previously happened in the bazel macro - i can either readd by adding extensions names to source bazel build files - or we can validate these in generate_extension_db

i have added a regression test for generate_extension_db this should be removed before landing i think

there is an override extensions_build_config.bzl file for mac osx that is still using the old format - nothing seems to break - but im still wondering whether it should be updated to use the newer format

related to this im noticing that other repos also use or override the extensions_build_config.bzl file - eg

• https://github.com/envoyproxy/envoy-mobile
• https://github.com/GoogleCloudPlatform/esp-v2

not sure how these will be affected by changing the format of the config in this way - im happy to open downstream PRs to fix if necessary

im also noticing that there are some dev docs that will need to be updated...

re breaking https://github.com/envoyproxy/envoy-mobile - i have opened a ticket here envoyproxy/envoy-mobile#1475 to resolve

re breaking https://github.com/GoogleCloudPlatform/esp-v2 - this seems to be quite a way behind envoy HEAD so its unlikely to break soon - i can open a ticket there warning of impending extensions config change
