2014-03-05base.bbclass: Deprecate the PRINC logicRichard Purdie1
The PRINC logic is now deprecated, the PR server should be used to handle the automatic incrementing of the PR (package release) field. Add a warning message to alert users to the change. The functionality will be removed in the next release cycle. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2014-03-05sanity.bbclass: support wildcards in SANITY_TESTED_DISTROSOlof Johansson1
With this change, you can use shell like globbing expressions (as supported by Python's fnmatch) for entries in SANITY_TESTED_DISTROS. This makes it possible to say that, e.g. "all Debian 7 Wheezy releases are supported" with the entry "Debian-7.*".

AUTOTOOLS_COPYACLOCAL variable Introduce a AUTOTOOLS_COPYACLOCAL variable which forces the copy of the aclocal files even when a configure.ac/.in file isn't present. Use this new feature in alsa-tools. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2014-03-05autotools: Limit aclocal files to those in dependenciesRichard Purdie1
We still occasionally see race issues with cp-noerror, and it copies too many files, we should limit the the m4 files to those explicitly in the DEPENDS for the recipe. This change takes advantage of the BB_TASKDEPDATA data from bitbake to only copy in those files listed in the manifest of the recipes in DEPENDS.

2014-02-28autotools-brokensep: Mark recipes with broken separate build dir supportRichard Purdie1
This patch goes through the OE-Core recipes and marks those which use autotools but don't support a separate build directory (${S} != ${B}). A new class, autotools-brokensep is used for this purpose. This doesn't introduce any change in behaviour in its own right. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2014-02-28kernel-yocto: always checkout machine branch when existing validate_branchesBruce Ashfield1
The validate_branches routine is responsible for ensuring that the specified SRCREV exists, and that the tree has been prepared for eventual patching starting directly from that SRCREV. On exit, the routine checks out the specified machine branch and the preparation is complete .. except if a KMETA branch isn't used, we exit early since the branch can't be validated. To make the exit condition consistent for all cases, we can move the KMETA validation inside a conditional and allow the same exit path for both cases.

2014-02-28base: Remove pointless createCopy/update_data callsRichard Purdie1
I was asked why we had these copy and update_data calls. I can offer no good explanation other than them perhaps once being needed for reasons long since forgotten and superceeded. With modern bitbake these should not be needed and shouldn't have been for a long time. Lets therefore remove them and simplify the code.

2014-02-24sstate: Drop 'SafeDep' code from setscene validation functionRichard Purdie1
I have a feeling this code exists from the time before we had proper coverage of one sstate task by another task. At that time it was a "poor" persons version of that idea, we now have much better code internal to bitbake which handles this. Worse, this code actually breaks certain rebuild scenarios, e.g.: bitbake libtool-cross bitbake libtool-cross -c cleansstate rm tmp -rf bitbake libtool-cross would fail as binutils-cross wasn't installed from sstate. The easiest fix is to remove the obsolete/broken code. [YOCTO #5773] Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2014-02-24package: Drop do_package_write taskRichard Purdie4
The reasons this task was introduced are lost in the mists of time. It allowed for the a single "package_write" task instead of spelling out the explicit package backends, however in all but one case we do that anyway. As such as might as well give in and delete the task, converting that single reference into explicit dependencies. This gives bitbake a bit less work to to when processing the runqueue since there are less tasks (but more dependencies in some cases).

* Sort the list so it's at least in some form of logical order. I looked at sorting by dependencies, but that's a topological sort, and given no such function is shipped as part of the python standard libraries it would seem excessive to pull one in just for this.

2014-02-24classes/sstate: fix taints being undone on execution of sstate tasksPaul Eggleton1
The code here that deletes stamps was also deleting the taint files; so forcing an sstate task with -f would force it to execute and then because the taint file was deleted in the process, the next execution would simply restore the output from sstate again. We need to exclude the taint files just like we did in bb.build.make_stamp(). Fixes [YOCTO #5805].

2014-02-17classes/populate_sdk_base: fix race condition with do_rootfsPaul Eggleton1
do_rootfs has ${S} in cleandirs, and during do_populate_sdk we call exec_func() several times, which by default uses ${B} as the working directory. If do_populate_sysroot and do_rootfs race against eachother, the directory may not exist at the exact instant that the setup code for do_populate_sdk tries to cd into it. We don't actually use ${B} for do_populate_sysroot so we can set it to something else just for that task to avoid the race. NOTE: because this task name contains an underscore, the override will not work; the BitBake patch that changes these to hyphens for the task override is required for this patch to work (but won't break things without it.)

2014-02-17package.bbclass: do_split_packages should always return something.Josua Mayer1
So far, when do_split_packages is passed a non-existing folder, it will return nothing. While building Mesa with PACKAGECONFIG="egl gles" for qemux86, do_package threw a nice exception on a line reading "pkgs += do_split_packages": "Exception: TypeError: 'NoneType' object is not iterable" I think a function should always return something, and in this specific case, returning an empty list should be right.

2014-02-17classes/cpan-base: fix signatures changing when perl is in sysrootPaul Eggleton1
The previous fix for this same issue (OE-Core rev f31f6a70ec24e8c9515d69c5092e15effc5e7d4d) was not sufficient - we are setting the PERLVERSION variable from the get_perl_version function, but we're setting it using immediate expansion; thus the value is going into the signature and is still different between the time the recipe is cached on an empty TMPDIR and after perl is in the sysroot and we run bitbake -S perf. We could remove the immediate expansion, but that would mean the get_perl_version function would be called more often, so just set vardepvalue on the PERLVERSION variable to fix the problem instead.

I got hit by a missing dependency in generation of sum.jffs2 images - at runtime, when images are generated using bitbake pool, it is possible for sum.jffs2 image to be scheduled for generation before jffs2 image is fully generated.

Class is used to save data about errors after every task that failed. Errors saved as json files in ERROR_REPORT_DIR (defaults to tmp/log/error-report). To use this class one has to add INHERIT += "report-error" to local.conf. scripts/send-error-report is a simple script that sends the json file to a HTTP server that collects data (git://git.yoctoproject.org/error-report-web is a Django web interface that can be used to receive and visualize the error reports).

2014-02-13kernel.bbclass, base.bbclass: Fix support for old kernel configurationOtavio Salvador2
This solves a regression introduced by OE-Core:9b75f6a (kernel: use oldnoconfig before yes '' | make oldconfig). The original oe_runmake explicitly calls 'die' command in case of failure so the fallback code never runs. The fallback code needs to handle the oe_runmake return code to call the backward compatible callback so we introduced a new command called oe_runmake_call which is used by oe_runmake. This does not change the functional behaviour of oe_runmake so it avoids any change except for the code which does need to handle the oe_runmake exit code.

2014-02-12package: Remove the before do_build constraint of the do_package taskRichard Purdie1
Currently, if you bitbake xxxx, it will restore the package_write_, packagedata, populate_sysroot *and* the package data from sstate. We generally care about the packagedata and the actual packages, we no longer need/care about the do_package data itself unless something is going to repackage.

2014-02-11sstate: Exclude SSTATE_EXTRAPATH from checksumsRichard Purdie1
After the change to allow target recipes to depend on native recipes, the native checksums becomes all the more critical. Add to this that we're now accounting for pre/postfuncs and we have a cache reuse issue since the distro LSB string is getting coded in when it shouldn't be. This excludes that string and allows one set of native sstate to share checksums with another set from a different host distro. They're separated into different directories so this is fine for our use cases. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2014-02-11classes/buildhistory: avoid buildhistory triggering rebuilds (again)Paul Eggleton1
Postfuncs are now incorporated into task signatures as of BitBake rev b84d010144de687667cf855ddcb41c9b863c236e, so we need to exclude the one we're adding to do_fetch. The change to the SSTATEPOSTINSTFUNCS variable value was also entering the signatures of do_populate_sysroot and probably other tasks, so we need to use a slightly hacky trick to avoid that as well. Apart from the final do_rootfs / do_populate_sysroot, this now means that adding and removing INHERIT += "buildhistory" will not cause tasks to be re-run.

The USERADD_ERROR_DYNAMIC needs to check that both users and groups that are defined need to be represented as static ids, or an error should occur. For the user check, we want to make sure the uid is a numeric value. (The gid can be name, as the GROUPADD check will validate for a number there -- or during install useradd will fail if that group is not defined.)

2014-02-11kernel: stop using -exec rm for deleting filesBruce Ashfield1
Removing files from the source tree via find, exec and rm is not the most efficient operation, due to (among other things) the many forked processes. If we use -delete, it saves a significant amount of time. But -delete does not work with -prune (since it forces -depth). To maintain the lib, tools and scripts source files, we can hide them temporarily, skip their hidden directories and then finally restore them. Time for install before this change: real 2m48.563s user 0m35.220s sys 0m33.036s Time for install after this change: real 1m21.301s user 0m33.160s sys 0m28.388s We could further speed this up by using inline perl to delete the files, but that complexity is avoided for now.
