# Chromium's QUIC
|
||
|
|
|
||
|
|
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).
|
||
|
|
|
||
|
|
## Build files
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
## Cloning process
|
||
|
|
|
||
|
|
At a basic level, the original cloning process was as follows:
|
||
|
|
1. Copy net/third_party/quic and add its files to BUILD.gn.
|
||
|
|
2. Try to compile.
|
||
|
|
3. Fix errors by copying evidently necessary files from Chromium and adding
|
||
|
|
them to the appropriate BUILD.gn
|
||
|
|
4. Repeat from 2 until everything works.
|
||
|
|
|
||
|
|
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
