-## Configuration of working clone repositories
-
-These are repositories (Clone 1 .. N in the image) usually setup to
-avoid permission problems with the working directory used by ikiwiki
-itself. They also represent the most convenient way to add content to
-the wiki on a different machine (that is, not the machine the wiki is
-published on) which is more convenient.
-
-The use case for these clones is this: If you want to edit your wiki
-on your development box, or on your laptop, you usually set up a clone
-as above. But very often, you also want to test what the changes look
-like, locally, before pushing it to the root repository and publishing
-the wiki for the world to see.
-
-In order to do this, you should another setup file and setup a private
-ikiwiki on the local machine (your laptop, for instance) where you do
-most of your editing. You will also need to set up a webserver, and
-install ikiwiki on this machine. Only when you are happy with any
-changes do you push them to the root repository.
-
-Here are some things to be aware of when configuring ikiwiki on the
-local machine:
-
-* By default, ikiwiki pulls and pushes from `origin`. This is not
- ideal for the working clones on the local machine, since you might
- go through several iterations of a page before pushing to the bare
- root of the repository tree and publishing it on your public
- wiki. In the configuration, set:
-
- gitorigin_branch => "",
- ## git post-commit wrapper
- wrapper => "/working/dir/.git/hooks/post-commit",
-
- Then just committing should refresh the private ikiwiki on the local
- host.
-
-* You can optionally enable to the [[plugins/mirrorlist]] plugin,
- and configure it so that each page links to the corresponding page on the
- server.
-
-Now just run `ikiwiki -setup wiki.setup -getctime` and you should be
-good to go. (You only need the slow `-getctime` option the first time you
-run setup.)
-
-Use standard git commands to handle pulling from and pushing to the server.
-
-Note: Currently, after pulling changes, you will need to manually update
-the wiki, with a command such as `ikiwiki -setup wiki.setup -refresh`. This
-is because git 1.5.4 doesn't have a hook that is run locally after pulling
-changes. Newer versions of git will have a `post-merge` hook that should
-work for this purpose.
+## git repository with untrusted committers
+
+By default, anyone who can commit to the git repository can modify any file
+on the wiki however they like. A `pre-receive` hook can be set up to limit
+incoming commits from untrusted users. Then the same limits that are placed
+on edits via the web will be in effect for commits to git for the users.
+They will not be allowed to edit locked pages, they will only be able to
+delete pages that the [[plugins/remove]] configuration allows them to
+remove, and they will only be allowed to add non-page attachments that the
+[[plugins/attachment]] configuration allows.
+
+To enable this, you need to set up the git repository to have multiple
+committers. Trusted committers, including the user that ikiwiki runs as,
+will not have their commits checked by the `pre-receive` hook. Untrusted
+committers will have their commits checked. The configuration settings to
+enable are `git_test_receive_wrapper`, which enables generation of a
+`pre-receive` hook, and `untrusted_committers`, which is a list of
+usernames of the untrusted committers.
+
+Note that when the `pre-receive` hook is checking incoming changes, it
+ignores the git authorship information, and uses the username of the unix
+user who made the commit. Then tests including the `locked_pages` [[PageSpec]]
+are checked to see if that user can edit the pages in the commit.
+
+You can even set up an anonymous user, to allow anyone to push
+changes in via git rather than using the web interface.
+
+## Optionally using a local wiki to preview changes
+
+When working on the "working clones" to add content to your wiki,
+it is common (but optional) practice to preview your changes using a
+private wiki on the local host before publishing the updates by
+sending it to the root repository. If you do want to setup a private
+wiki, you will have to have another setup file and and an ikiwiki
+installation on your local machine. You will need all the packages
+this implies -- a web server, git, ikiwiki, etc. However, there is a
+_caveat_: by default, ikiwiki pulls and pushes from `origin`. This is
+not ideal for the working clones on the local machine, since you might
+go through several iterations of a page before pushing to the bare
+root of the repository tree (and thus publishing it on your public wiki).
+You do not want the action of refreshing the local wiki in order to
+review your work to accidentally publish the
+contents before you are ready. In order to prevent the git push that
+is the normal behaviour of ikiwiki, set the configuration of the local wiki:
+
+ gitorigin_branch => "",
+ ## git post-commit wrapper
+ wrapper => "/working/dir/.git/hooks/post-commit",
+
+Then just committing should refresh the private ikiwiki on the local
+host. Now just run `ikiwiki -setup localwiki.setup -getctime` and
+you should be good to go. (You only need the slow `-getctime` option
+the first time you run setup.) Use standard git commands to handle
+pulling from and pushing to the server. **Note**: Currently, after
+pulling changes from the bare root repository, you will need to
+manually update the local wiki, with a command such as `ikiwiki
+-setup localwiki.setup -refresh`. This is because git 1.5.4 doesn't
+have a hook that is run locally after pulling changes. Newer
+versions of git will have a `post-merge` hook that should work for
+this purpose.

+## Fix for error on git pull origin
+
+Error message when running git pull origin:
+
+ You asked me to pull without telling me which branch you
+ want to merge with, and 'branch.master.merge' in
+ your configuration file does not tell me either. Please
+ name which branch you want to merge on the command line and
+ try again (e.g. 'git pull <repository> <refspec>').
+ See git-pull(1) for details on the refspec.
+
+ If you often merge with the same branch, you may want to
+ configure the following variables in your configuration
+ file:
+
+ branch.master.remote = <nickname>
+ branch.master.merge = <remote-ref>
+ remote.<nickname>.url = <url>
+ remote.<nickname>.fetch = <refspec>
+
+ See git-config(1) for details.
+
+The solution is to run this command in your srcdir:
+
+ git config branch.master.remote origin
