Tsrc

Highlights

Add support for multiple remotes

yaml
still valid (implicit 'origin' remote)
src: foo
url: gitgithub.com/foo

also valid (two explicit remotes)
src: fooo
remotes:
- { name: origin, url: gitgithub.com:john/foo }
- { name: upstream, url: gitgithub.com:foo/foo}

not valid (ambiguous)
src: foo
url: gitgithub.com:john/foo
remotes:
- { name: upstream, url: gitgithub.com:foo/foo }


Thanks tst2005 and cgestes for their help with the configuration format.


tsrc foreach

* `tsrc foreach`: add a `--group` option to select the repositories to run the command on. Fix 40

Other fixes

* Fix [113](https://github.com/SuperTanker/tsrc/issues/113): do not hide branch when showing tag status.
* Add support for Python 3.7

* Add support for setting approvers with the `-r,--approvers` option in `tsrc push` (GitLab Enterprise Edition only).

* Fixed regression: `tsrc push` was no longer able to create a merge request on GitLab if `--target` was not set.

Highlights

* Preliminary GitHub support
* `tsrc push`: new features and bug fixes
* Improved fixed reference handling
* Support for shallow clones

See below for the details.

Preliminary GitHub support

* Added support for creating merge requests on GitHub. No configuration required. Just make sure you are using `tsrc` from a repository which has a URL starting with `gitgithub.com`.

`tsrc` will prompt you once for your login and password and then store an API token.

Afterwards, you'll be able to use `tsrc` push to:

* Create a pull request (or update it if it already exists)
* Assign people to the request (with the `-a/--assignee` option)
* Request reviewers (with the `--reviewers` option)
* Merge the pull request (with the `--merge` option)

This change has no impact if you were already using `GitLab`.

`tsrc push`: new features and bug fixes

* Add ``--close`` option.
* **Breaking change**: `-m/--message` option is gone, use `--title` instead. There's a concept of "description" or "message" for pull requests and merge requests, but the value of the option was only used to update the *title*, so it had to be renamed.
* Do not assume local and remote tracking branch have the same name.
* Allow using `tsrc push <local>:<remote>` to explicitly specify local and remote branch names.
* Fix bugs when target is not specified on the command line. See [this commit](https://github.com/SuperTanker/tsrc/pull/107/commits/5940f96284fe13d9977fafbb05fcc3dad15ac32d) for details.
* Fix missing merge requests in `tsrc push` (see [issue 80](https://github.com/SuperTanker/tsrc/issues/80)). Patch by maximerety.


Improve fixed reference handling

**Breaking change**: Instead of using `fixed_ref` in the manifest, you should now use `tag` or `sha1`:

*old*:
yaml
repos:
- src: gitexample.com/foo
fixed_ref: 42a70


*new*:

repos:
- src: gitexample.com/foo
tag: v0.1


See the [dedicated section about manifest format](ref/formats.mdrepos) and the [57 pull request discussion](https://github.com/SuperTanker/tsrc/pull/57) for the details.

This allow us to implement different behaviors depending on whether or not the fixed ref is a tag or just a sha1.

Support for shallow clones

To save time and space, you can use `tsrc init --shallow` to only have shallow clones in your workspace.

Note that due to limitations in `git` itself, the `shallow` option cannot be used with a fixed SHA1. If you need this, prefer using a `tag` instead.


Misc

* Organization `TankerApp` was renamed to `SuperTanker`. New urls are:

* [github.com/SuperTanker/tsrc](https://github.com/SuperTanker/tsrc) for the git repository
* [supertanker.github.io/tsrc](https://supertanker.github.io/tsrc) for the documentation


* We now use [pipenv](https://docs.pipenv.org/) for dependency handling.

* Improve `tsrc status` to handle tags. Patch by arnaudgelas
* Fix crash when running `tsrc version`

* Improve `tsrc status` output. Now also shows number of commits ahead and behind, and display a short SHA-1 when not on any branch. Initial patch by arnaudgelas.
