From: Nathan Rossi <[email protected]> Add a new selftest to validate minidebuginfo support. This selftest builds a complete target image with PACKAGE_MINIDEBUGINFO enabled. ELFs included in the image are expected to have minidebuginfo included in the resulting executables and shared libraries, the self test validates this by unpacking the image and checking for the associated ".gnu_debugdata" section on busybox and libc ELFs.
Signed-off-by: Nathan Rossi <[email protected]> Signed-off-by: Alexandre Belloni <[email protected]> (cherry picked from commit 5063a31ad05b75ec6ac12158fe759e81fcdb1585) --- The commit from master relies on the 'target_sys' parameter of runCmd, this was introduced in afa3d3ba00b40fd29e9852eeaa2c2c9b68f18659 (langdale and later). That commit could be backported alongside this commit however it adds '/bin' to the PATH by default which may cause issues (?). As such this commit is modified to add the TARGET_SYS path into the PATH environment passed into the runCmd call. --- meta/lib/oeqa/selftest/cases/minidebuginfo.py | 49 +++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 meta/lib/oeqa/selftest/cases/minidebuginfo.py diff --git a/meta/lib/oeqa/selftest/cases/minidebuginfo.py b/meta/lib/oeqa/selftest/cases/minidebuginfo.py new file mode 100644 index 0000000000..414dad64a3 --- /dev/null +++ b/meta/lib/oeqa/selftest/cases/minidebuginfo.py @@ -0,0 +1,49 @@ +# +# Copyright OpenEmbedded Contributors +# +# SPDX-License-Identifier: MIT +# +import os +import subprocess +import tempfile +import shutil + +from oeqa.selftest.case import OESelftestTestCase +from oeqa.utils.commands import bitbake, get_bb_var, runCmd + + +class Minidebuginfo(OESelftestTestCase): + def test_minidebuginfo(self): + target_sys = get_bb_var("TARGET_SYS") + binutils = "binutils-cross-{}".format(get_bb_var("TARGET_ARCH")) + + self.write_config(""" +PACKAGE_MINIDEBUGINFO = "1" +IMAGE_FSTYPES = "tar.bz2" +""") + bitbake("core-image-minimal {}:do_addto_recipe_sysroot".format(binutils)) + + deploy_dir = get_bb_var("DEPLOY_DIR_IMAGE") + native_sysroot = get_bb_var("RECIPE_SYSROOT_NATIVE", binutils) + readelf = get_bb_var("READELF", "core-image-minimal") + + # add usr/bin/${TARGET_SYS} to PATH + env = os.environ.copy() + paths = [os.path.join(native_sysroot, "usr", "bin", target_sys)] + paths += env["PATH"].split(":") + env["PATH"] = ":".join(paths) + + # confirm that executables and shared libraries contain an ELF section + # ".gnu_debugdata" which stores minidebuginfo. + with tempfile.TemporaryDirectory(prefix = "unpackfs-") as unpackedfs: + filename = os.path.join(deploy_dir, "core-image-minimal-{}.tar.bz2".format(self.td["MACHINE"])) + shutil.unpack_archive(filename, unpackedfs) + + r = runCmd([readelf, "-W", "-S", os.path.join(unpackedfs, "bin", "busybox")], + native_sysroot = native_sysroot, env = env) + self.assertIn(".gnu_debugdata", r.output) + + r = runCmd([readelf, "-W", "-S", os.path.join(unpackedfs, "lib", "libc.so.6")], + native_sysroot = native_sysroot, env = env) + self.assertIn(".gnu_debugdata", r.output) + --- 2.38.1
