[swift-users] Trouble with initial checkout

Wed Dec 7 22:00:32 CST 2016

I’ve been using Git for about 8 years now, so I know my way around. But in checking out a release of Swift, I’m running into errors.

```
$ git clone -q -b swift-3.0.2-PREVIEW-1 https://github.com/apple/swift.git;
Note: checking out 'dc2c3d580f52367eebaada34901a945466e947df'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>
```

So far, so good. (I also did this exact same thing with swift-3.0.1-RELEASE — same issue.)

Now, for the util scripts:

```
$ cd swift && \
    ./utils/update-checkout --clone && \
    ./utils/build-script -r \
;

When you have resolved this problem, run "git rebase --continue".
If you prefer to skip this patch, run "git rebase --skip" instead.
To check out the original branch and stop rebasing, run "git rebase --abort".

```

I tried following the white rabbit for a while, resolving the merge conflicts (in favor of non-HEAD), but after a while I decided that this probably wasn’t normal and I should try asking here.

Am I encountering something weird?

Thanks for any pointers.
