working clones.
One of the leaf node clone repositories is special; it has working
-directory which is used to compile the wiki from, and is also used by the
+directory which is used to compile the wiki, and is also used by the
[[cgi]] to commit changes made via the web interface. It is special
-since the `post-commit` hook for the bare root repository is used to
+since the `post-update` hook for the bare root repository is used to
trigger an update of this repository, and then an ikiwiki refresh
updates the published wiki itself.
The other (optional) leaf node repositories are meant for you to work
on, and commit to, changes should then be pushed to the bare root
-repository. In theory, you could work on the same leaf node repository
-that ikiwiki uses to compile the wiki from, and the [[cgi]] commits
-to, as long as you ensure that permissions and ownership don't hinder
-the working of the [[cgi]]. This can be done, for example, by using
-ACL's, in practice, it is easier to just setup separate clones for
-yourself.
+repository.
So, to reiterate, when using Git, you probably want to set up three
repositories:
* The root repository. This should be a bare repository (meaning that
it does not have a working tree checked out), which the other
repositories will push to/pull from. It is a bare repository, since
- there are problems pushing to a repository that has a working
+ git does not support pushing to a repository that has a working
directory. This is called _repository_ in [[ikiwiki-makerepo]]'s
- manual page. Nominally, this bare repository has a `post-commit` hook
+ manual page. This bare repository has a `post-update` hook
that either is or calls ikiwiki's git wrapper, which changes to the
- working directory for ikiwiki, does a _git pull_, and refreshes ikiwiki
+ working directory for ikiwiki, does a `git pull`, and refreshes ikiwiki
to regenerate the wiki with any new content. The [[setup]] page describes
how to do this.
* The second repository is a clone of the bare root repository, and
has a working tree which is used as ikiwiki's srcdir for compiling
- the wiki. **Never** push to this repository. When running as a
- [[cgi]], the changes are committed to this repository, and pushed to
- the master repository above. This is called _srcdir_ in
- [[ikiwiki-makerepo]]'s manual page.
+ the wiki. **Never** push to this repository. It is wise to not make
+ changes or commits directly to this repository, to avoid conflicting
+ with ikiwiki's own changes. When running as a [[cgi]], the changes
+ are committed to this repository, and pushed to the master repository
+ above. This is called _srcdir_ in [[ikiwiki-makerepo]]'s manual page.
* The other (third, fourth, fifth, sixth -- however many pleases you)
repositories are also clones of the bare root repository above --
hack on your wiki. you can commit local changes to the version on
the laptop, perhaps while offline. Any new content should be pushed to the
bare master repository when you are ready to publish it, and then
- the post-commit hook of the bare repository will ensure that the
+ the post-update hook of the bare repository will ensure that the
ikiwiki's source directory is updated, and the ikiwiki refreshed
with the new content.
Instead, clone the bare repository as mentioned above, and push
**only** to the bare repository.

## git repository with multiple committers
commit to an ikiwiki git repository. As the [[security]] page mentions,
for a secure ikiwiki installation, only one person should be able to write
to ikiwiki's srcdir. When other committers make commits, their commits
-should go to the bare repository, which has a `post-update` hook that uses
-ikiwiki to pull the changes to the srcdir.

One setup that will work is to put all committers in a group (say,
"ikiwiki"), and use permissions to allow that group to commit to the bare git
group. Take care that ikiwiki uses a umask that does not cause files in
the srcdir to become group writable. (umask 022 will work.)
+## 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|tips/untrusted_git_push]], 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,
gitorigin_branch => "",
## git post-commit wrapper
- wrapper => "/working/dir/.git/hooks/post-commit",
+ git_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
