Run the "clean" target in debian/rules + +Alternatively, instead of using quilt directly, you can drop the patch in to +debian/patches and add the name of the patch to debian/patches/series. + +------------------------------------ +Guide To The X Strike Force Packages +------------------------------------ + +The X Strike Force team maintains X packages in git repositories on +git.debian.org in the pkg-xorg subdirectory. 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. --- libxdmcp-1.1.3.orig/debian/changelog +++ libxdmcp-1.1.3/debian/changelog @@ -0,0 +1,244 @@ +libxdmcp (1:1.1.3-0ubuntu5) jammy; urgency=high + + * No change rebuild for ppc64el baseline bump. + + -- Julian Andres Klode Thu, 24 Mar 2022 17:15:10 +0100 + +libxdmcp (1:1.1.3-0ubuntu4) impish; urgency=medium + + * No-change rebuild to build packages with zstd compression. + + -- Matthias Klose Thu, 07 Oct 2021 12:19:34 +0200 + +libxdmcp (1:1.1.3-0ubuntu3) hirsute; urgency=medium + + * No-change rebuild to drop the udeb package. + + -- Matthias Klose Thu, 25 Feb 2021 06:58:59 +0100 + +libxdmcp (1:1.1.3-0ubuntu2) hirsute; urgency=medium + + * No-change rebuild to drop the udeb package. + + -- Matthias Klose Mon, 22 Feb 2021 10:35:04 +0100 + +libxdmcp (1:1.1.3-0ubuntu1) eoan; urgency=medium + + * New upsteam version + + -- Sebastien Bacher Sat, 24 Aug 2019 16:36:56 +0300 + +libxdmcp (1:1.1.2-3) unstable; urgency=medium + + * Merge 1:1.1.2-1.1 NMU, lost by mistake in 1:1.1.2-2. + + -- Julien Cristau Thu, 02 Mar 2017 15:27:19 +0100 + +libxdmcp (1:1.1.2-2) unstable; urgency=medium + + * CVE-2017-2625: Build-depend on libbsd-dev for arc4random_buf. + Closes: #856399. + + -- Emilio Pozuelo Monfort Tue, 28 Feb 2017 22:47:22 +0100 + +libxdmcp (1:1.1.2-1.1) unstable; urgency=medium + + * Non-maintainer upload. + * Remove &fullrelver; usage from doc/xdmcp.xml to make libxdmcp-dev M-A:same + safe when built with different versions of xorg-sgml-doctools.
