This page is intended to provide some basic background about development nits and the maintenance of the developer site.
The Apache HTTP Server Project has switched to Subversion for hosting its source code.
To check out the 2.4.x branch:
svn checkout http://svn.apache.org/repos/asf/httpd/httpd/branches/2.4.x httpd-2.4.x
To check out the current development version (as of this writing, 2.5.x), use:
svn checkout http://svn.apache.org/repos/asf/httpd/httpd/trunk httpd-trunk
Committers should check out via https instead of http (so that they can commit their changes). For more info about Subversion, please read the ASF version control FAQ.
The developers continue to seek to maintain module compatibility between 2.4.1 and future 2.4 releases for administrators and end users, while continuing the forward progress that has made the 2.2 server faster and more scalable.
Almost all files relating to Apache, both the actual sources and the files that aren't part of the distribution, are now maintained in an SVN repository. Here is the way in which changes are applied:
This step only needs to be performed once (unless the private working directory is tainted or deleted.) Committers should use a URL prefix of https on the checkout, to save themselves headaches later.
This should probably be done daily or even more frequently during periods of high activity.
There are several different branches under the httpd subtree in the Apache SVN repository that pertain to the different releases. The top level can be perused with the SVN ViewCVS pages. The main subtrees pertaining to the httpdserver source are:
To create a directory tree containing the 2.2 sources, and call it httpd-2.2, change your current directory to the parent of the tree and then check the 2.2 sources out as follows:
% cd /usr/local/apache % svn checkout http://svn.apache.org/repos/asf/httpd/httpd/branches/2.2.x httpd-2.2
To create a directory tree containing the 2.4 sources, and call it httpd-2.4, change your current directory to the parent of the tree and then check the 2.4 sources out as follows:
% cd /usr/local/apache % svn checkout http://svn.apache.org/repos/asf/httpd/httpd/branches/2.4.x httpd-2.4
If you want to check out the bleeding edge of development, the httpd-2.5 development tree (slated for a release 2.6), and call it httpd-trunk, checkout as follows:
% cd /usr/local/apache % svn checkout http://svn.apache.org/repos/asf/httpd/httpd/trunk httpd-trunk
This subtree contains the files that live at http://httpd.apache.org/. The directory on the host that maps to that URL is actually a set of checked-out working copies of the SVN files.
The SVN URL
Like the httpd-sitesubtree, this one is used to maintain the files that comprise a website - in this case, http://www.apache.org/dist/httpd/. Also like the previous subtree, the directory on the server is a checked-out working copy of this subtree. However, since this is a distribution directory, we only have the surrounding documentation and control files checked into this subtree -- the actual tarballs are simply copied to www.apache.org.
The SVN URL is https://svn.apache.org/repos/asf/httpd/httpd/dist.
Committers will generally deal with this subtree when "rolling" a release. This is a series of steps taken to create a complete new release of the Apache httpd software. Amongst other things, the key to this subtree is the tools/directory, which contains the release.shshell script. More information on the policies and procedures relating to rolling releases can be found on the Release Guidelines page.
A brief overview of getting started with SVN committer access can be found here. One key change to note is that SSH is not used anymore for committer access, due to the functional differences with SVN.
