fauxfaux / jdk9-repotools

This repo exists to work around Oracle's OpenJDK project using hg, and using it badly.

flatten.py

1. git clone hg::...jdk9
2. for each submodule, git submodule add that into this repo
3. destory the .gitmodules file (i.e don't commit anything)

This leaves you with a super weird git repo:

$ cat jdk9/.git/config
[core]
	repositoryformatversion = 0
	filemode = true
	bare = false
[remote "origin"]
	url = hg::http://hg.openjdk.java.net/jdk9/jdk9
	fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
	remote = origin
	merge = refs/heads/master
[submodule "corba"]
	url = hg::http://hg.openjdk.java.net/jdk9/jdk9/corba
[submodule "jaxp"]
	url = hg::http://hg.openjdk.java.net/jdk9/jdk9/jaxp
[submodule "jaxws"]
	url = hg::http://hg.openjdk.java.net/jdk9/jdk9/jaxws
[submodule "langtools"]
	url = hg::http://hg.openjdk.java.net/jdk9/jdk9/langtools
[submodule "nashorn"]
	url = hg::http://hg.openjdk.java.net/jdk9/jdk9/nashorn
[submodule "hotspot"]
	url = hg::http://hg.openjdk.java.net/jdk9/jdk9/hotspot
[submodule "jdk"]
	url = hg::http://hg.openjdk.java.net/jdk9/jdk9/jdk

% ls jdk9/.git/modules
corba  hotspot  jaxp  jaxws  jdk  langtools  nashorn

Unlike with normal submodules, you can just cd into these things and pull them, and you should.

Once you've pulled everything, you can:

mkdir flattened; (cd flattened; git init)
python3 flatten.py
cd flattened
git reset --hard

Then, you'll have a sane repo!
