classes/base: reformat HOSTTOOLS error

2017-03-16T22:11:32+00:00

Adjust the message slightly to make it clearer, in particular mentioning the HOSTTOOLS variable. (From OE-Core rev: e022b27d189c1dcc7b3baea2b99dba8d724e6e2b) Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

base/bitbake.conf: Filter contents of PATH to only allow whitelisted tools

2017-03-11T16:09:14+00:00

We currently have a determinism problem in that the host tools present in PATH can influence the build. In particular, the presence of pkg-config on the build host can mask missing pkgconfig class dependencies. This adds in a new HOSTTOOLS variable and then uses it to set up a directory of symlinks to the whitelisted host tools. This directory is placed as PATH instead of the usual /usr/bin:/bin and so on. This should improve determinism of builds and avoid the issues which have been particularly obvious since the introduction of recipe specific sysroots. If users find there is a tool missing, they can extend HOSTTOOLS from a global class or global conf file. Right now the settings should be enough to build everything in OE-Core.

base.bbclass: improve wording when skipping recipes with incompatible licenses

2017-03-08T11:52:56+00:00

The previous wording, e.g. ERROR: wget was skipped: incompatible with license GPLv3 isn't very clear and could be taken to imply that the recipe is incompatible with its own license.

2017-02-15T17:29:55+00:00

Now that the datastore works dynamically we don't need the update_data calls so we can just remove them. They're not actually done anything at all for a while. (From OE-Core rev: 8de0c5d3bd01919e2bf0394f9c485936d6098cec) Signed-off-by: Richard Purdie

Switch to Recipe Specific Sysroots

2017-01-23T12:05:17+00:00

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.

classes/base: fix license file checksumming when source not under TMPDIR

2016-12-14T12:30:49+00:00

With the changes to the code for extracting source for a recipe, we are properly executing the tasks for a recipe, which means their stamps (and therefore signatures) are important. When running devtool extract on the lsof recipe I noticed that do_fetch and do_unpack were executing a second time when we called for do_patch, and this turned out to be because LIC_FILES_CHKSUM in that recipe contains an entry which is an absolute path (has ${S} at the start). Normally this wouldn't be an issue since S is under TMPDIR and thus the existing code would ignore it, however devtool's extraction code extracts to a temporary directory which is not under TMPDIR; the result was the path to this file was not being ignored and the second time around when the license file had been extracted it was incorporated into the signature. We don't want this, so explicitly exclude S as well as B and WORKDIR for good measure.

base.bbclass: Use bb.fatal() instead of raising FuncFailed

2016-10-04T15:29:04+00:00

This sets a good example and avoids unnecessarily contributing to perceived complexity and cargo culting. Motivating quote below: < kergoth> the *original* intent was for the function/task to error via whatever appropriate means, bb.fatal, whatever, and funcfailed was what you'd catch if you were calling exec_func/exec_task. that is, it's what those functions raise, not what metadata functions should be raising < kergoth> it didn't end up being used that way < kergoth> but there's really never a reason to raise it yourself FuncFailed.__init__ takes a 'name' argument rather than a 'msg' argument, which also shows that the original purpose got lost.

SDK: Allow changing SDKMACHINE without wiping TMP folder

2016-09-28T09:16:03+00:00

When changing SDKMACHINE, we may encounter an error forcing us to wipe the TMP folder. Since only SDK_ARCH is captured in the PN of the crosssdk recipes, changes to SDK_OS result in conflicts. Eventually we hit the error: ERROR: ...: The recipe <...> is trying to install files into a shared area when those files already exist. The build has stopped as continuing in this scenario WILL break things This patchset addresses the problem by SDK_SYS as the recipe name suffix instead of SDK_ARCH.
