2016-12-07kernel-yocto: exit on non-zero return codeBruce Ashfield1
Historically the processing of kernel meta data contained some commands that exited with a non-zero return code. Special processing was required to properly deal with their exit. That is no longer true, and instead of handling all return codes and doing an explicit 'exit' call, we can remove set -e from the routine and have all errors be trapped and stop processing.

2016-12-07kernel.bbclass: let do_deploy depend on do_packagedataRobert Yang1
The do_deploy runs depmodwrapper which requires pkgdata/kernel-depmod/kernel-abiversion, which is generated by PACKAGEFUNCS. So we need let do_deploy depend on do_packagedata. This can fix the errors which happens sometimes when kernel upgrades: DEBUG: Executing shell function do_deploy Error: Kernel version 4.8.8-WR9.0.0.1_standard does not match kernel-abiversion (4.8.8-WR9.0.0.0_standard) And we only see this error when kernel upgrades and rebuild, but doesn't see it in a normal build, this is becuase depmodwrapper doesn't exit error when kernel-depmod/kernel-abiversion doesn't exit, it just prints an error which should go into log.do_deploy: if [ ! -r /path/to/sysroots/qemux86-64/pkgdata/kernel-depmod/kernel-abiversion ]; then echo "Unable to read: /path/to/sysroots/qemux86-64/pkgdata/kernel-depmod/kernel-abiversion" >&2 else [foo] fi We can see that there is no "exit 1", I guess it was designed to let it can run without kernel-abiversion Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com>

2016-11-30systemd.bbclass: don't block on service restartMark Asselstine1
The current class works fine when a recipe uses SYSTEMD_AUTO_ENABLE 'enable' and has no on device pkg_postinst(), ie when the postinst is run as part of rootfs creation. However, when there is a component of pkg_postinst() that is run on device the 'systemctl restart' is run as part of the run_postinsts.service at boot. This results in the boot spinning indefinitely with: [ *** ] A start job is running for Run pending postinsts (7s / no limit) The issue could potentially be that the packages service has an 'After' clause which comes later in the boot, beyond run_postinsts.service, creating a chicken before the egg scenario. Even service files without an 'After' clause cause this situation however. Despite this not being the cause of the issue this fix will prevent this scenario from happenning. Using strace we are able to find that during boot, when run_postinsts.service is running attempting to start or restart any service will result in the call get stuck on poll(). Since the run_postinsts.service does not monitor the outcome of the call to restart we can work around this by using '--no-block'.

2016-11-30qemuboot.bbclass: do not hook into do_rootfsPatrick Ohly1
Writing qemuboot.conf in write_qemuboot_conf() does not modify the rootfs and thus conceptually shouldn't be executed as part of rootfs creation. Running it as separate task is cleaner and fixes the problem of missing qemuboot.conf files for meta-swupd virtual images; those images replace do_rootfs and ROOTFS_POSTPROCESS_COMMANDs don't run at all. The task gets added such that it runs roughly at the same time as before. Probably it doesn't actually need to depend on do_rootfs, but this way we don't write a useless qemuboot.conf in cases where do_rootfs fails.

2016-11-28conf: add C++ flags for uninative interoperatilityRoss Burton1
Create a common include file for compiler flags which allow native binaries to be interoperable on a wide range of hosts. In particular the C++ ABI is problematic so choose the CXX11 version to allow interoperation between gcc4 and gcc5 based hosts. Moving this to a common include instead of uninative.bbclass allows uninative to be configured later and used in the eSDK (where its mandatory) even if the base configuration doesn't enable uninative by default (e.g. nodistro in OE-Core).

If you run "devtool modify" on such a recipe, make changes to the commit for the patch and then run devtool update-recipe, we need to correctly associate the commit back to the compressed patch file and re-compress the patch, neither of which we were doing previously.

2016-11-23cmake.bbclass: Set CXXFLAGS and CFLAGSKhem Raj1
We strip the TOOLCHAIN_OPTIONS and HOST_CC_ARCH from CC/CXX in cmake.bbclass whereas CFLAFS and CXXFLAGS assume that TOOLCHAIN_OPTIONS are part of CC/CXX variables, this causes compile failures when cmake is running compiler tests during configure on some architectures especially armhf, because hf ABI information -mfloat-abi is part of TOOLCHAIN_OPTIONS, so what happens is that testcase gets compiled without hard-float, howver, during linking the float ABI option is passed via LDFLAGS, now linker rejects this and fails like /mnt/a/build/tmp-glibc/sysroots/x86_64-linux/usr/libexec/arm-oe-linux-gnueabi/gcc/arm-oe-linux-gnueabi/6.2.0/ld: error: cmTC_27947 uses VFP register arguments, CMakeFiles/cmTC_27947.dir/src.cxx.o does not mnt/a/build/tmp-glibc/sysroots/x86_64-linux/usr/libexec/arm-oe-linux-gnueabi/gcc/arm-oe-linux-gnueabi/6.2.0/ld: failed to merge target specific data of file CMakeFiles/cmTC_27947.dir/src.cxx.o collect2: error: ld returned 1 exit status This means that CMake now fails the configure time test too which is not right, e.g. it might disable features which actually do exist and should be enabled e.g. in case above it is resulting as below Performing C++ SOURCE FILE Test HAS_BUILTIN_SYNC_SUB_AND_FETCH failed with the following output: Its actually a bug in CMake see https://gitlab.kitware.com/cmake/cmake/issues/16421 CMake is ignoring CMAKE_CXX_FLAGS when using CHECK_CXX_SOURCE_COMPILES function. Until it is fixed upstream, we add HOST_CC_ARCH and TOOLCHAIN_OPTIONS to CFLAGS and CXXFLAGS, so that we can ensure that compiler invocation remains consistent.

2016-11-15image-buildinfo: treat staged changes as modified branch, tooAndré Draszik1
When staging changes in a layer using git add, image-buildinfo doesn't detect this as a modification, because of the way it uses git diff. Surely, merely staging, but not committing changes to git should not result in image-buildhistory assuming that the git repository hasn't been modified compared to the branch HEAD, this state should be treated similarly to modifications being unstaged.

2016-11-06classes/license: copy licenses even if there are no checksummed filesRoss Burton1
Previously do_populate_lic would bail writing the license files (such as the MIT license text) to deploy/licenses/${PN}/ if there were no files listed in LIC_FILES_CHKSUM. In general this isn't a problem since LIC_FILES_CHKSUM was effectively a required field, and for packages which don't have traditional content was generally set to a separate license such as ${COREBASE}/meta/COPYING.MIT. However LIC_FILES_CHKSUM is now only required if there are sources in SRC_URI, so oe-core b18fa5f removed these now redundant values. The unexpected side effect of this is that that recipes that generate their content (such as os-release) or are otherwise "interesting" (such as perf) don't have their license files copied over, resulting in warnings from do_rootfs. Resolve this by not returning early if LIC_FILES_CHKSUM is empty, and always copy the references license files. Signed-off-by: Ross Burton <ross.burton@intel.com>
2016-11-06classes/populate_sdk_ext: require uninativePaul Eggleton1
It seems that possibly due to OE-Core commit ac59063bee0e32d0737340974f657341717a6abe, binaries produced without uninative aren't compatible with the uninative glibc. I did try earlier to ensure that the eSDK could work without uninative since the default configuration in OE-Core does not enable it, but it seems like I didn't go far enough. Given the practical considerations, just give up and require uninative to be enabled in order to build the eSDK. I'm not particularly happy about this, but I don't seem much of an alternative.

2016-11-06classes/populate_sdk_ext: prevent invalid TEMPLATECONF entering eSDKPaul Eggleton1
If you are using a repository which contains a .templateconf file that sets TEMPLATECONF to point into a layer it contains, but you aren't using that layer in your bblayers.conf, the eSDK would produce an error during the preparation step of the installation. An example would be using the poky repository but setting DISTRO to your own custom distro and removing meta-poky from your bblayers.conf. The eSDK doesn't support creating new build directories, so we don't care about the templates and can thus force a known good value to prevent this from happening. Fixes [YOCTO #10568].

2016-11-06classes/nativesdk: set SDK_OLDEST_KERNEL appropriatelyPaul Eggleton2
SDK_OLDEST_KERNEL currently only controls the check on SDK installation, however as with OLDEST_KERNEL it should be controlling the OLDEST_KERNEL value for building glibc used in the SDK. Thus, set it in nativesdk.bbclass. This means we need to move the default to bitbake.conf so that it can be seen in both places. Also set a more reasonable default for SDK_OLDEST_KERNEL for x86/x86-64 as glibc 2.24 still supports back to 2.6.32 there and there are still people wanting to build SDKs that will install on older distros (e.g. CentOS 6). However it's not possible to set this with overrides since there aren't any for the SDK_ARCH, however we can instead set the variable from conf files in conf/machine-sdk especially as there is now a soft default for SDKMACHINE.
