Most upstream packages +are actually maintained in git repositories as well, so they often +just need to be pulled into git.debian.org in a "upstream-*" branch. +Otherwise, the upstream sources are manually installed in the Debian +git repository. + +The .orig.tar.gz upstream source file could be generated this +"upstream-*" branch in the Debian git repository but it is actually +copied from upstream tarballs directly. + +Due to X.org being highly modular, packaging all X.org applications +as their own independent packages would have created too many Debian +packages. For this reason, some X.org applications have been grouped +into larger packages: xutils, xutils-dev, x11-apps, x11-session-utils, +x11-utils, x11-xfs-utils, x11-xkb-utils, x11-xserver-utils. +Most packages, including the X.org server itself and all libraries +and drivers are, however maintained independently. + +The Debian packaging is added by creating the "debian-*" git branch +which contains the aforementioned "upstream-*" branch plus the debian/ +repository files. +When a patch has to be applied to the Debian package, two solutions +are involved: +* If the patch is available in one of the upstream branches, it + may be git'cherry-picked into the Debian repository. In this + case, it appears directly in the .diff.gz. +* Otherwise, the patch is added to debian/patches/ which is managed + with quilt as documented in /usr/share/doc/quilt/README.source. + +quilt is actually invoked by the Debian X packaging through a larger +set of scripts called XSFBS. XSFBS brings some other X specific +features such as managing dependencies and conflicts due to the video +and input driver ABIs. +XSFBS itself is maintained in a separate repository at + git://git.debian.org/pkg-xorg/xsfbs.git +and it is pulled inside the other Debian X repositories when needed. + +The XSFBS patching system requires a build dependency on quilt. Also +a dependency on $(STAMP_DIR)/patch has to be added to debian/rules +so that the XSFBS patching occurs before the actual build. So the +very first target of the build (likely the one running autoreconf) +should depend on $(STAMP_DIR)/patch. It should also not depend on +anything so that parallel builds are correctly supported (nothing +should probably run while patching is being done). And finally, the +clean target should depend on the xsfclean target so that patches +are unapplied on clean. + +When the upstream sources contain some DFSG-nonfree files, they are +listed in text files in debian/prune/ in the "debian-*" branch of +the Debian repository. XSFBS' scripts then take care of removing +these listed files during the build so as to generate a modified +DFSG-free .orig.tar.gz tarball. --- libxxf86dga-1.1.4.orig/debian/changelog +++ libxxf86dga-1.1.4/debian/changelog @@ -0,0 +1,173 @@ +libxxf86dga (2:1.1.4-1) unstable; urgency=low + + * New upstream release. + * Bump debhelper compat level to 7. + * Use dh_prep instead of dh_clean -k. + * Use dpkg-buildflags. + * Disable silent build rules. + + -- Julien Cristau Mon, 12 Aug 2013 23:16:53 +0200 + +libxxf86dga (2:1.1.3-2+deb7u1) wheezy-security; urgency=high + + * integer overflows calculating memory needs for replies [CVE-2013-1991] + * buffer overflows due to not validating length or offset values in replies + [CVE-2013-2000] + + -- Julien Cristau Wed, 15 May 2013 18:55:18 +0200 + +libxxf86dga (2:1.1.3-2) unstable; urgency=low + + * Pull build fix from upstream for BSD (closes: #671047) + + -- Julien Cristau Sat, 30 Jun 2012 20:44:15 +0200 + +libxxf86dga (2:1.1.3-1) unstable; urgency=low + + * New upstream release. + * Remove David and Andres from Uploaders. + * d/rules: add build-{arch,indep} target, don't use dh_testroot in clean. + * Build for multiarch. + * Drop useless Depends on x11-common. + + -- Julien Cristau Mon, 30 Apr 2012 15:11:07 +0200 + +libxxf86dga (2:1.1.2-1) unstable; urgency=low + + [ Julien Cristau ] + * Rename the build directory to not include DEB_BUILD_GNU_TYPE for no + good reason.
