How to submit patch

1. Watch libxcam project
   go to libxcam, and hit 'watch'.
   Then you can receive any others commit/comments
2. Fork libxcam to your own account, hit 'fork'
   
3. Get libxcam code to local.
   $ git clone git@github.com:user/libxcam.git
4. Add 'upstream' for rebase
   $ git remote add upstream https://github.com/intel/libxcam.git
$ git fetch upstream
   
5. Edit patch.
6. Format patch before commit.
   $ ./code_style.sh
$ git commit -m "xxxx"
7. Rebase with upstream
   $ git fetch upstream
$ git rebase upstream/master
   If failed, fix conflicts first.
8. Push commit to your account.
   $ git push origin
9. Go to github home, create 'pull request'
10. Wait for review, If accepted, maintainer would merge to upstream; else, continue edit patch

How to sync up local repo with upstream

• Every time, before edit source code, run
  $ git fetch upstream
$ git rebase upstream
  

• If there's conflicts but you are sure can be fixed. try to edit conflict files, then
  $ git add xxxx # xxxx means conflict files
  $ git rebase --continue

• If maintainer fixed your patch. Try
  $ git fetch upstream
$ git format-patch -2 #backup your local patches, 2 means there are 2 local patches to backup
  $ git reset --hard upstream/master # be careful of --hard, this may reset all your local patches. that's why need to backup at first
  $ git am 000*.patch # to restore you local patches, if there's conflicts, try to fix.
