VCS Synchronizers
=================

[](#vcs-synchronizers)

This repository contains multiple synchronizers to synchronize multiple VCS repositories (of the same type).

Symmetric vs. Asymmetric synchronisation
----------------------------------------

[](#symmetric-vs-asymmetric-synchronisation)

Symmetric synchronisation means that each repository is compared and synchronized against each other. If a conflict is detected - two remotes have divergent branches - no repository of the concerned branch is synchronized.

Asymmetric synchronisation means that one - the primary - repository is compared and synchronized against all the others repositories. If a conflict is detected - one remote branch is ahead of the primary - the branch in the concerned repository is not synchronized.

Working repository
------------------

[](#working-repository)

The synchronizers work on a local *working repository*. But they won't create them for you! This let you keep control of what happened.

Here is an example, how you could create the local *working repository*.

```
use ContaoCommunityAlliance\BuildSystem\Repository\GitRepository;

$path = tempnam(sys_get_temp_dir());
unlink($path);
mkdir($path);

$repository = new GitRepository($path);
$repository->init()->execute();
$repository->remote()->add('github', 'git@github.com:contao-community-alliance/vcs-synchronizer.git')->execute();
$repository->remote()->add('bitbucket', 'git@bitbucket.org:contao-community-alliance/vcs-synchronizer.git')->execute();
```

GIT Synchronizers
=================

[](#git-synchronizers)

Symmetric branch synchronizer
-----------------------------

[](#symmetric-branch-synchronizer)

**CLI usage**

```
./bin/git-branches-symmetric-sync -b github -b bitbucket /path/to/repository
```

**PHP usage**

```
use ContaoCommunityAlliance\BuildSystem\VcsSync\Synchronizer\GitSymmetricBranchSynchronizer;

$synchronizer = new GitSymmetricBranchSynchronizer(
    // the working repository
    $repository,
    // the remotes to synchronize
    ['github', 'bitbucket']
);
$synchronizer->setLogger($logger);
$synchronizer->sync();
```

Asymmetric branch synchronizer
------------------------------

[](#asymmetric-branch-synchronizer)

**CLI usage**

```
./bin/git-branches-asymmetric-sync -b github -b bitbucket -p github /path/to/repository
```

**PHP usage**

```
use ContaoCommunityAlliance\BuildSystem\VcsSync\Synchronizer\GitAsymmetricBranchSynchronizer;

$synchronizer = new GitAsymmetricBranchSynchronizer(
    // the working repository
    $repository,
    // the remotes to synchronize
    ['github', 'bitbucket'],
    // the primary remote
    'github'
);
$synchronizer->setLogger($logger);
$synchronizer->sync();
```

Asymmetric tag synchronizer
---------------------------

[](#asymmetric-tag-synchronizer)

**CLI usage**

```
./bin/git-tags-asymmetric-sync -b github -b bitbucket -p github /path/to/repository
```

**PHP usage**

```
use ContaoCommunityAlliance\BuildSystem\VcsSync\Synchronizer\GitAsymmetricTagSynchronizer;

$synchronizer = new GitAsymmetricTagSynchronizer(
    // the working repository
    $repository,
    // the remotes to synchronize
    ['github', 'bitbucket'],
    // the primary remote
    'github'
);
$synchronizer->setLogger($logger);
$synchronizer->sync();
```
