From 00a5df641b94ef47eec36e742630db7b659102a4 Mon Sep 17 00:00:00 2001 From: Mazliana Date: Fri, 23 Aug 2019 10:29:18 +0800 Subject: oeqa/kerneldevelopment: Able to apply a single patch to the Linux kernel source MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Purpose of kernel development is basically to customize our own recipes kernel by reused existing recipes.   This is an initiative of automating manual kernel development test cases. Applying a single patch to the Linux kernel source is one of the manual test cases of kernel development. Objective of this test is as a developer we can make changes of a file in kernel source and able to apply a single patch to the kernel source.   ref:https://wiki.yoctoproject.org/wiki/Kernel_Development_Test_Cases Signed-off-by: Mazliana Signed-off-by: Richard Purdie --- meta/lib/oeqa/selftest/cases/kerneldevelopment.py | 67 +++++++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 meta/lib/oeqa/selftest/cases/kerneldevelopment.py (limited to 'meta/lib/oeqa/selftest') diff --git a/meta/lib/oeqa/selftest/cases/kerneldevelopment.py b/meta/lib/oeqa/selftest/cases/kerneldevelopment.py new file mode 100644 index 0000000000..a61876ee61 --- /dev/null +++ b/meta/lib/oeqa/selftest/cases/kerneldevelopment.py @@ -0,0 +1,67 @@ +import os +from oeqa.selftest.case import OESelftestTestCase +from oeqa.utils.commands import runCmd, get_bb_var +from oeqa.utils.git import GitRepo + +class KernelDev(OESelftestTestCase): + + @classmethod + def setUpClass(cls): + super(KernelDev, cls).setUpClass() + # Create the recipe directory structure inside the created layer + cls.layername = 'meta-kerneltest' + runCmd('bitbake-layers create-layer %s' % cls.layername) + runCmd('mkdir -p %s/recipes-kernel/linux/linux-yocto' % cls.layername) + cls.recipes_linuxyocto_dir = os.path.join \ + (cls.builddir, cls.layername, 'recipes-kernel', 'linux', 'linux-yocto') + cls.recipeskernel_dir = os.path.dirname(cls.recipes_linuxyocto_dir) + runCmd('bitbake-layers add-layer %s' % cls.layername) + + @classmethod + def tearDownClass(cls): + runCmd('bitbake-layers remove-layer %s' % cls.layername, ignore_status=True) + runCmd('rm -rf %s' % cls.layername) + super(KernelDev, cls).tearDownClass() + + def setUp(self): + super(KernelDev, self).setUp() + self.set_machine_config('MACHINE = "qemux86-64"\n') + + def test_apply_patches(self): + """ + Summary: Able to apply a single patch to the Linux kernel source + Expected: The README file should exist and the patch changes should be + displayed at the end of the file. + Product: Kernel Development + Author: Yeoh Ee Peng + AutomatedBy: Mazliana Mohamad + """ + runCmd('bitbake virtual/kernel -c patch') + kernel_source = get_bb_var('STAGING_KERNEL_DIR') + readme = os.path.join(kernel_source, 'README') + + # This test step adds modified file 'README' to git and creates a + # patch file '0001-KERNEL_DEV_TEST_CASE.patch' at the same location as file + patch_content = 'This is a test to apply a patch to the kernel' + with open(readme, 'a+') as f: + f.write(patch_content) + repo = GitRepo('%s' % kernel_source, is_topdir=True) + repo.run_cmd('add %s' % readme) + repo.run_cmd(['commit', '-m', 'KERNEL_DEV_TEST_CASE']) + repo.run_cmd(['format-patch', '-1']) + patch_name = '0001-KERNEL_DEV_TEST_CASE.patch' + patchpath = os.path.join(kernel_source, patch_name) + runCmd('mv %s %s' % (patchpath, self.recipes_linuxyocto_dir)) + runCmd('rm %s ' % readme) + self.assertFalse(os.path.exists(readme)) + + recipe_append = os.path.join(self.recipeskernel_dir, 'linux-yocto_%.bbappend') + with open(recipe_append, 'w+') as fh: + fh.write('SRC_URI += "file://%s"\n' % patch_name) + fh.write('FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"') + + runCmd('bitbake virtual/kernel -c clean') + runCmd('bitbake virtual/kernel -c patch') + self.assertTrue(os.path.exists(readme)) + result = runCmd('tail -n 1 %s' % readme) + self.assertEqual(result.output, patch_content) -- cgit 1.2.3-korg
