Changes

Source While there is no Rsync repository for CentOS source rpms , they can only be downloaded manually through yum or curl/wgetor yum. Therefore, since there creating a bash script to automate download processes is no Rsync repository for Centos source rpmshighly recommended.

: <u>Solution</u>: Add 4.x support to the system checking script(just a IF statement of checking version number)

; Build test/check failed: <u>Reason</u>: Can be random reasons or the software is just unable to run perfectly on AArch64: <u>Solution</u>: Try to look for solutions, otherwise comment out the <tt>%check</tt> section in spec file ; BuildError <span>:</span> No matching arches were found: <u>Reason</u>: Package only supports the specific architectures on the <tt>ExclusiveArch</tt> list in the spec file: <u>Solution</u>: Checkout similar version of the package on [http://arm.koji.fedoraproject.org Fedora ARM Koji ] and [http://buildlogs.centos.org/centos/7 CentOS AArch64 repo ] and determine whether the package is possible to support AArch64 or not

There a few standards to follow during modificationto make life easier:

* When commenting out a existing line of code, add one more '''<tt>%''' </tt> before any rpm macro otherwise rpmbuild will treat it as a error/warning. For instance:

* Add '''<tt>.leap''' </tt> after the release version, add '''<tt>.leap.1'''</tt>, '''<tt>.leap.2''' </tt> ... and so on for further modifications

=== Rebranding Re-branding === The packages that contain the word ''extension <tt>.centos'' </tt> in their release version are branded packages. In order to properly rebranding re-branding those packages for LEAP, here is the checklist:* Replace the word ''"CentOS'' " or ''"CentOS Linux'' " with ''"LEAP'' ", and "centos" with "leap" in spec package descriptions and patches (make sure they are branding-related)* Replace CentOS branding patches with LEAP branding patchesone

* Replace CentOS links with links for LEAP links accordingly

* Remove CentOS/RHEL certificate certificates, binaries, or any enterprise support files and binaries  ==== Particular branded packages ====

: '''Libreport''' and '''abrt''' are the library and application for automatic bug detection and reporting to RHEL bug tracker servers. Since CentOS added several significant patches to both packages for supporting their own bug tracker, removing those patches can be very complicated process. The best way to solve this problem is retrieving the original RHEL versions from http://git.centos.org, add our own de-branding patches, and bump the version-release number + ''.leap'' to match the requirements of dependency.

It is possible that a A few packages in the package set contain patches or sources having identical file names. When installing source rpms to rpmbuild tree (<tt>$HOME/rpmbuild/*</tt>), try to avoid installing too many of them at a the same time (50+). Wipe the rpmbuild tree after finishing modification and build of those packages on Koji. There are a few problematic packages have been discovered:* OpenJDK 6 / '''java-1.7 / .0-openjdk''' and '''java-1.8 packages.0-openjdk'''* '''xorg-x11-drv-dummy ''' and '''xorg-x11-drv-fbdev''' == Other special cases ==* '''libreoffice''' - Require at least 50GB of space to build* '''binutils''' - was intentionally upgraded to 2.24, be careful not to downgrade it.* '''httpd''' - <tt>centos-noindex.tar.gz</tt> contains branded default webpages, replace it with <tt>leap-noindex.tar.gz</tt> from previous version of httpd = Fixing broken dependencies =After all of the packages have been done, it's time to fix minor broken dependencies. <tt>repoclosure</tt> and <tt>leap-closure-report.sh</tt> (by Chris Markieta) are the tools to check dependency stats of a repository. You should always check the build-tag repository since new packages may require some of the old packages.
