You need to install the git command line tool, part of git-core (on Debian/Ubuntu) or git (Fedora/CentOS) package:
apt-get install git-core
Create the folder where you want to clone the repository, for example:
mkdir ~/kamailio cd ~/kamailio
If you have developer write access to GIT repository, clone the repository with:
git clone ssh://email@example.com/sip-router kamailio-dev
Replace userid with your developer GIT username.
If you don't have developer write access, you can clone read-only the repository with:
git clone --depth 1 git://git.sip-router.org/sip-router kamailio-dev
The clone is tracking automatically the remote master branch (the development version).
Not an absolute MUST, but it SHOULD be used almost always. It helps to track changes and follow the development easier (better commit mail messages and ChangeLogs are easier to generate).
Note: there is no list of owners and the code parts, the guidelines here are not to prevent contributions to any parts of code, but to keep the coherence of the code and sanity of development. As generic rule, if you are not the initial author of a component, then someone else is the maintainer. If you don't know who is that developer, just ask on mailing list sr-dev [at] lists.sip-router.org.
Whenever possible, commit first into master branch and then backport the patch - a recommended way is to cherry-pick the patch by commit id from master branch in your target branch.
By committing first into master branch, we ensure that the development version is always the most up-to-date. Also, people can review and test the commit from master branch before it is backported to a stable branch.
If it is a major change, then it is recommended to commit first into a personal or tmp branch. Then send an announcement to sr-dev mailing list, describing shortly the changes and where they are located. In this way, first, we avoid development conflicts between main (other) author(s) of the code and the other developers. Second, other developers can review or test, giving feedback or suggesting improvements or alternatives.
In some cases, the main author of the code may provide a different implementation, for the same purpose, that will fit better in existing architecture or future plans for that component. Very often, the contributions will be just merged in the main devel branch.
Each developer has access to a personal branch on GIT remote repository hosted on sip-router.org. The name of the branch starts with the GIT username of developer, followed by a forward slash and then the effective branch name. For example:
Only the respective developer can do commit in such branch.
If many developers need to work on a branch, it can be created in the tmp/ space:
Please create the commit messages following the GIT convention:
Think of the first line as of an email “Subject” line. In fact it will be used as “Subject” in the generated commit emails and it will also be used when generating the Changelog (e.g. git log –pretty=oneline).
Please start always with the prefix of the subsystem that is modified by the commit, for example:
If the module_name is duplicated, one in modules_k and one in modules_s, add (k) or (s), depending where the changes was done, for example:
Examples of commit messages:
usrloc(s): fixed name conflict - destroy_avps() renamed to reg_destroy_avps() to avoid conflicts with the usr_avp.h version.
core: loadpath can now use a list of directories - loadpath can use a list of directories separated by ':', e.g.: loadpath "modules:modules_s:modules_k". First match wins (e.g. for loadmodule "textops" if modules/textops.so or modules/textops/textops.so exists, it will be loaded and the search will stop).
The suggestions here target to make easier to track the changes and do the backporting to stable branches whenever is the case:
When you finish doing the changes, you can see affected files with:
If you are in the root of source tree, you can commit all changes with:
git commit .
In case you added new files, first you have to add them with:
git add path/to/file
To split the commits, you can give the list of files as argument to git commit command:
git commit path/to/file1 /path/to/file2
You can commit the changes in a directory with:
git commit path/to/directory/
For example, commit the changes for module auth:
git commit modules/auth/
