This directory contains a copy of Chromium‘s QUIC, along with what is (hopefully) a minimum set of dependencies from Chromium. All of the build files were rewritten to avoid also porting Chromium’s build infrastructure (gn flags, configs, and absolute-path imports).
The QUIC code is all covered by the BUILD.gn in this directory. The remaining Chromium code is covered by a BUILD.gn for each top-level directory under src/ (e.g. net, url, etc.). src/base/ is handled slightly differently, because it is a submodule where we still want to rewrite BUILD.gn, as well as some generated files. In this case, we use build/base/, which contains our new BUILD.gn and generated files from an existing Chromium checkout.
At a basic level, the original cloning process was as follows:
The process is mostly encapsulated in the script clone_helper.sh
. The only caveat is that the original cloning process was done as described, but now src/base/ is included as a submodule with its BUILD.gn and generated files in build/base/.
The original clone is from Chromium commit 8b90885e60134c34176df2dd1834a94dbd6b73b9.
