Here is a quickie guide to get you started in IPA development.
|
|
|
|
Dependencies
|
|
------------
|
|
|
|
The quickest way to get the dependencies needed for building is:
|
|
|
|
# yum install rpm-build `grep "^BuildRequires" freeipa.spec.in | awk '{ print $2 }' | grep -v "^/"`
|
|
|
|
This is currently (01/05/11):
|
|
|
|
yum install 389-ds-base-devel mozldap-devel svrcore-devel nspr-devel \
|
|
openssl-devel openldap-devel e2fsprogs-devel krb5-devel nss-devel \
|
|
libcap-devel python-devel autoconf automake libtool popt-devel m4 \
|
|
policycoreutils python-setuptools python-krbV xmlrpc-c-devel \
|
|
libcurl-devel gettext authconfig libuuid-devel
|
|
|
|
Building
|
|
--------
|
|
|
|
From the root of the source tree run:
|
|
$ make rpms
|
|
|
|
The resulting rpm packages are in dist/rpms:
|
|
|
|
# yum --nogpgcheck localinstall dist/rpms/*
|
|
# ipa-server-install
|
|
|
|
It may be possible to do a simple make all install but this has not been
|
|
well-tested. Additional work is done in pre/post install scripts in the ipa
|
|
spec file.
|
|
|
|
Developing plugins
|
|
------------------
|
|
|
|
It is possible to do management plugin development within the source tree.
|
|
|
|
To start with, you need a full IPA install on the current system. Build and
|
|
install the rpms and then configure IPA using ipa-server-install.
|
|
|
|
Get a TGT for the admin user with: kinit admin
|
|
|
|
Next you'll need 2 sessions in the source tree. In the first session run
|
|
python lite-server.py. In the second session you can run the ./ipa
|
|
tool and it will make requests to the lite-server listening on 127.0.0.1:8080.
|
|
|
|
This makes developing plugins much faster and you can also make use of the
|
|
Python pdb debugger on the server side.
|
|
|
|
You'll find you may need to refresh the underlying build if schema or other
|
|
changes are required.
|
|
|
|
Testing
|
|
-------
|
|
|
|
We use python nosetests to test for regressions in the management framework
|
|
and plugins. You'll need the python-nose package installed to run the tests.
|
|
|
|
To run all of the tests you will need 2 sessions, one to run the lite-server
|
|
and the other to execute the tests. You'll also need a TGT before starting
|
|
the lite-server:
|
|
|
|
% kinit admin
|
|
% make test
|
|
|
|
Some tests may be skipped. For example, all the XML-RPC tests will be skipped
|
|
if you haven't started the lite-server. The DNS tests will be skipped if
|
|
the underlying IPA installation doesn't configure DNS, etc.
|
|
|
|
API.txt
|
|
-------
|
|
The purpose of the file API.txt is to prevent accidental API changes. The
|
|
program ./makeapi creates file and also validates it (with the --validate
|
|
option). This validation is part of the build process.
|
|
|
|
There are three solutions to changes to the API:
|
|
|
|
1. Changes to existing API require a change to the MAJOR version.
|
|
2. Addition of new API requires a change to the MINOR version.
|
|
3. Or just back out your changes and don't make an API change.
|
|
|
|
If the API changes you'll need to run ./makeapi to update API.txt and
|
|
commit it along with VERSION with your API change.
|
|
|
|
If a module is optionally loaded then you will need to be able to
|
|
conditionally load it for API validation. The environment variable
|
|
api.env.validate_api is True during validation.
|
|
|
|
General Notes
|
|
-------------
|
|
IPA is not relocatable.
|
|
|
|
When building rpms the version contains the GIT id in the version. To prevent
|
|
this pass the argument IPA_VERSION_IS_GIT_SNAPSHOT=yes to make.
