Chapter 7. Sanitization of the source

This is suitable for avoiding auto-generated files and removes them in the “debian/rules clean” target

	Note
	The “debian/rules clean” target is called before the “dpkg-source --build” command by the dpkg-buildpackage command and the “dpkg-source --build” command ignores removed files.

This is for the non-native Debian package.

The problem of extraneous diffs can be fixed by ignoring changes made to parts of the source tree by adding the “extend-diff-ignore=…​” line in the debian/source/options file.

debian/source/options to exclude the config.sub, config.guess and Makefile files: 

# Don't store changes on autogenerated files
extend-diff-ignore = "(^|/)(config\.sub|config\.guess|Makefile)$"

	Note
	即使您无法删除文件，这种做法总可以正常工作。您无需在每次构建之前手动删除文件并手动进行恢复。

	Tip
	如果您转而使用 debian/source/local-options 文件，您可以在生成的源码包中隐藏该项设置。这种做法在本地非标准版本控制系统和您的打包工作有冲突时可能有用。

This is for the native Debian package.

You can exclude some files in the source tree from the generated tarball by tweaking the file glob by adding the “tar-ignore=…​” lines in the debian/source/options or debian/source/local-options files.

Note

If, for example, the source package of a native package needs files with the file extension .o as a part of the test data, the setting in “Section 4.5, “devscripts setup”” is too aggressive. You can work around this problem by dropping the -I option for DEBUILD_DPKG_BUILDPACKAGE_OPTS in “Section 4.5, “devscripts setup”” while adding the “tar-ignore=…​” lines in the debian/source/local-options file for each package.

The problem of extraneous contents in the second build can be avoided by restoring the source tree by committing the source tree to the Git repository before the first build.

您可以在第二次构建软件包之前恢复最初的源码树。例如：

 $ git reset --hard
 $ git clean -dfx
