Provide a way to rollback to certain commit

[Zeymo]

when commit has error , we want rollback configuration for a short time , like git revert commentId ... HEAD

Because 'short time' is ambiguous, I think adding an ability to add a revert commit for a certain revision is just enough. A user could choose to send a revert commit of the revert commit, i.e. revert the reversion.

Thanks for a good suggestion by the way. I'm curious if you are a LINE employee or just evaluating Central Dogma. Please feel free to hop into our Slack workspace so we could have some chat! :-)

Currently, does dogma provide a simple way to revert a file to previous version, i can't find similar api in docs. Is there any other way to achieve it? Thanks!

[trustin]

There's no such API in Central Dogma, but you can generate a revert commit and push it, i.e. there's no simple way, but we can implement it.

Is this function(revert a file to previous version) developing or released? Thanks

[trustin]

Not under development at the moment, but we hope to add it someday. Are you interested in working on this?

[puppylpg]

Yeah sure. I'm trying to using centraldogma to replace the config part on zookeeper. It'd be my pleasure to make some effort for this project.

Awesome! I think this feature can be implemented basically like this:

1. Expose a REST operation that allows a user send a revert request.
2. Create a Command implementation, which is a serializable form of (1).
3. Implement GitRepository.revert() operation, which will be invoked by CommandExecutor with the properties of (2).

Please feel free to let us know if you need any questions about this.

Thanks for your detailed guidance. I'll try to understand the code first quickly, then may disscuss more with you.
