2017-01-23classes/testsdk: Migrate to use the new OESDKExtTestContextAníbal Limón1
Signed-off-by: Aníbal Limón <anibal.limon@linux.intel.com>
2017-01-23oeqa/sdkext: Adds case and context modules.Aníbal Limón3
The extensible sdk context and case modules extends the sdk ones, this means that the tests from sdk are run also the sdkext tests. Enables support in context for use oe-test esdk command for run the test suites, the same options of sdk are required for run esdk tests. Removes old related to case and context inside oetest.py.

2017-01-23oeqa/sdkext: Move test cases inside cases directoryAníbal Limón3
For match with the new structure of the OEQA framework. In the new framework Test component base directory in this case sdk module will contain case and context implementations. [YOCTO #10599] Signed-off-by: Aníbal Limón <anibal.limon@linux.intel.com>
2017-01-23classes/testsdk: Remove the need of TEST_LOG_DIR variableAníbal Limón4
The TEST_LOG_DIR was used for store sdk_target_log this log contains the output of the run of build commands now that information could be found also on log.do_testsdk under WORKDIR. The log will continue to store into SDK_DIR instead of TEST_LOG_DIR. Signed-off-by: Aníbal Limón <anibal.limon@linux.intel.com>
2017-01-23oeqa/sdk/cases: Migrate tests to the new OEQA frameworkAníbal Limón7
Summary of the changes: - Remove auto extend_path using pkgutil at __init__, is not needed. - Change base class to OESDKTestCase. - Add td_vars attr to set dependencies of certain variables in test data. - Change skips from module level to class level because Test context (tc) now isn't at module level. - Variable names changes to be consistent (i.e. sdktestdir -> sdk_dir). [YOCTO #10599] - Don't use bb.utils functions use instead remove_safe and shutil for copy files. - SDKBuildProject pass test data variables instead of call getVar inside.

2017-01-23oeqa/utils: {Target,SDK,}BuildProject remove dependency of bbAníbal Limón3
Don't use bitbake references inside utils modules, in order todo that changes getVar calls for arguments in the __init__ method like dl_dir for all the classes and testlogdir, builddatetime in SDKBUildProject. Also don't export proxies inside _download_archive method, a good practice is to setup the proxies at init of the process instead of do it in this helper module.

2017-01-23oeqa/utils/__init__.py: Adds compatibility with bitbake loggerMariano Lopez1
The bitbake logger changes the way debug is logged and adds different levels within debug, this is passed as argument to the function and breaks compatibility with vanilla loggers. This implements a way to handle this adding a new function for debug, that will dispatch the correct logging method signature. Also overrides info method to use logging.INFO + 1 in order to see plain data. Also this commit fix the issue of not showing the test summary and results when running from bitbake.

This meta recipe is for building tools used by wic. It allows wic to find tools in recipe specific sysroot as all tools will be present in wic-tools sysroot. NOTE: task do_build_sysroot is created to ensure that sysroot is re-populated when package is built. Otherwise it will be taken from sstate and sysroot will not be populated. Generated wic-tools.env file for wic to be able to get values of wic-tools variables when wic run from bitbake. Also add dependency to grub-efi Without grub-efi test_iso_image test case fails with this error: AssertionError: Command 'wic create mkhybridiso --image-name core-image-minimal' returned non-zero exit status 1: Error: Please build grub-efi first Fixed by adding dependency wic-tools -> grub-efi.

2017-01-23bitbake.conf: Exclude extend_recipe_sysroot function from sstate checksumsRichard Purdie1
The extend_recipe_sysroot itself is excluded from the task hashes. This is because it only ever acts upon the contents of the task dependencies and hence those checksums accurately relfect what its doing. It does mean sysroots don't repopulate if this function changes but there are other easy ways to achieve that if needed. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2017-01-23selftest/devtool: Update to account for recipe specific sysrootRichard Purdie1
There is no common sysroot any more so add the libusb dependency using DEPENDS and check for the output in the sysroot output directory so the tests work with recipe specific sysroots. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2017-01-23Switch to Recipe Specific SysrootsRichard Purdie52
This patch is comparatively large and invasive. It does only do one thing, switching the system to build using recipe specific sysroots and where changes could be isolated from it, that has been done. With the current single sysroot approach, its possible for software to find things which aren't in their dependencies. This leads to a determinism problem and is a growing issue in several of the market segments where OE makes sense. The way to solve this problem for OE is to have seperate sysroots for each recipe and these will only contain the dependencies for that recipe. Its worth noting that this is not task specific sysroots and that OE's dependencies do vary enormously by task. This did result in some implementation challenges. There is nothing stopping the implementation of task specific sysroots at some later point based on this work but that as deemed a bridge too far right now. Implementation details: * Rather than installing the sysroot artefacts into a combined sysroots, they are now placed in TMPDIR/sysroot-components/PACKAGE_ARCH/PN. * WORKDIR/recipe-sysroot and WORKDIR/recipe-sysroot-native are built by hardlinking in files from the sysroot-component trees. These new directories are known as RECIPE_SYSROOT and RECIPE_SYSROOT_NATIVE. * This construction is primarily done by a new do_prepare_recipe_sysroot task which runs before do_configure and consists of a call to the extend_recipe_sysroot function. * Other tasks need things in the sysroot before/after this, e.g. do_patch needs quilt-native and do_package_write_deb needs dpkg-native. The code therefore inspects the dependencies for each task and adds extend_recipe_sysroot as a prefunc if it has populate_sysroot dependencies. * We have to do a search/replace 'fixme' operation on the files installed into the sysroot to change hardcoded paths into the correct ones. We create a fixmepath file in the component directory which lists the files which need this operation. * Some files have "postinstall" commands which need to run against them, e.g. gdk-pixbuf each time a new loader is added. These are handled by adding files in bindir with the name prefixed by "postinst-" and are run in each sysroot as its created if they're present. This did mean most sstate postinstalls have to be rewritten but there shouldn't be many of them. * Since a recipe can have multiple tasks and these tasks can run against each other at the same time we have to have a lock when we perform write operations against the sysroot. We also have to maintain manifests of what we install against a task checksum of the dependency. If the checksum changes, we remove its files and then add the new ones. * The autotools logic for filtering the view of m4 files is no longer needed (and was the model for the way extend_recipe_sysroot works). * For autotools, we used to build a combined m4 macros directory which had both the native and target m4 files. We can no longer do this so we use the target sysroot as the default and add the native sysroot as an extra backup include path. If we don't do this, we'd have to build target pkg-config before we could built anything using pkg-config for example (ditto gettext). Such dependencies would be painful so we haven't required that. * PKDDATA_DIR was moved out the sysroot and works as before using sstate to build a hybrid copy for each machine. The paths therefore changed, the behaviour did not. * The ccache class had to be reworked to function with rss. * The TCBOOTSTRAP sysroot for compiler bootstrap is no longer needed but the -initial data does have to be filtered out from the main recipe sysroots. Putting "-initial" in a normal recipe name therefore remains a bad idea. * The logic in insane needed tweaks to deal with the new path layout, as did the debug source file extraction code in package.bbclass. * The logic in sstate.bbclass had to be rewritten since it previously only performed search and replace on extracted sstate and we now need this to happen even if the compiled path was "correct". This in theory could cause a mild performance issue but since the sysroot data was the main data that needed this and we'd have to do it there regardless with rss, I've opted just to change the way the class for everything. The built output used to build the sstate output is now retained and installed rather than deleted. * The search and replace logic used in sstate objects also seemed weak/incorrect and didn't hold up against testing. This has been rewritten too. There are some assumptions made about paths, we save the 'proper' search and replace operations to fixmepath.cmd but then ignore this. What is here works but is a little hardcoded and an area for future improvement. * In order to work with eSDK we need a way to build something that looks like the old style sysroot. "bitbake build-sysroots" will construct such a sysroot based on everything in the components directory that matches the current MACHINE. It will allow transition of external tools and can built target or native variants or both. It also supports a clean task. I'd suggest not relying on this for anything other than transitional purposes though. To see XXX in that sysroot, you'd have to have built that in a previous bitbake invocation. * pseudo is run out of its components directory. This is fine as its statically linked. * The hacks for wayland to see allarch dependencies in the multilib case are no longer needed and can be dropped. * wic needed more extensive changes to work with rss and the fixes are in a separate commit series * Various oe-selftest tweaks were needed since tests did assume the location to binaries and the combined sysroot in several cases. * Most missing dependencies this work found have been sent out as separate patches as they were found but a few tweaks are still included here. * A late addition is that extend_recipe_sysroot became multilib aware and able to populate multilib sysroots. I had hoped not to have to add that complexity but the meta-environment recipe forced my hand. That implementation can probably be neater but this is on the list of things to cleanup later at this point. In summary, the impact people will likely see after this change: * Recipes may fail with missing dependencies, particularly native tools like gettext-native, glib-2.0-native and libxml2.0-native. Some hosts have these installed and will mask these errors * Any recipe/class using SSTATEPOSTINSTFUNCS will need that code rewriting into a postinst * There was a separate patch series dealing with roots postinst native dependency issues. Any postinst which expects native tools at rootfs time will need to mark that dependency with PACKAGE_WRITE_DEPS. There could well be other issues. This has been tested repeatedly against our autobuilders and oe-selftest and issues found have been fixed. We believe at least OE-Core is in good shape but that doesn't mean we've found all the issues. Also, the logging is a bit chatty at the moment. It does help if something goes wrong and goes to the task logfiles, not the console so I've intentionally left this like that for now. We can turn it down easily enough in due course.
