# Merging New XtraDB Releases (obsolete)

### Background

Percona used to maintain XtraDB as a patch series against the InnoDB plugin. This affected how we started merging XtraDB in.

Now Percona maintains a normal source repository on launchpad (`lp:percona-server`). But we continue to merge the old way to preserve the history of our changes.

### Merging

There used to be a `lp:percona-xtradb` tree, that we were merging from as:

```
bzr merge lp:percona-xtradb
```

Now we have to maintain our own XtraDB-5.5 repository to merge from. It is `lp:~maria-captains/maria/xtradb-mergetree-5.5`. Follow the procedures as described in [Merging with a merge tree](/docs/server/reference/product-development/mariadb-internals/mariadb-internals-documentation-merging-into-mariadb/merging-with-a-merge-tree.md) to merge from it.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://mariadb.com/docs/server/reference/product-development/mariadb-internals/mariadb-internals-documentation-merging-into-mariadb/merging-new-xtradb-releases-obsolete.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
