2016-05-25sstate.bbclass: Don't create symlinks, download to the correct locationRandy Witt1
Previously the sstate was all downloaded to the same directory and then symlinks were added in the directories that pointed to the siginfo and sstate in the parent directory. This change makes it so that now the files are just downloaded to the correct location without the need for symlinks.

2016-04-08sstatesig.py: Split single locked sigs check into multiple checksRandy Witt1
Add the SIGGEN_LOCKEDSIGS_TASKSIG_CHECK and SIGGEN_LOCKEDSIGS_SSTATE_EXISTS_CHECK variables to replace SIGGEN_LOCKEDSIGS_CHECK_LEVEL. SIGGEN_LOCKEDSIGS_TASKSIG_CHECK will no control whether there is a warning or error if a task's hash in the locked signature file doesn't match the computed hash from the current metadata. SIGGEN_LOCKEDSIGS_SSTATE_EXISTS_CHECK will control whther there is a warning or error if a task that supports sstate is in the locked signature file, but no sstate exists for the task. Previously you could only have warning/errors for both controlled by SIGGEN_LOCKEDSIGS_CHECK_LEVEL. This was an issue in the extensible sdk, because we know sstate won't exist for certain items in the reverse dependencies list for tasks. However, we still want to error if task signatures don't match.

2016-04-06useradd.bbclass: remove user/group created by the package in clean* taskMaxin B. John1
At present, if a recipe is built which creates users/groups via useradd.bbclass, those users/groups are not removed from sysroot when the recipe/package is cleaned using clean/cleansstate/cleanall or when a recipe is rebuild and 'unstaged' from the the sysroot.

2016-02-04sstate: Fix SSTATE_SWSPEC only used by populate_lic tasksRichard Purdie1
This variable is only used by populate_lic tasks (gcc-source overrides it) and refers to BPN. In recipes like gcc, where there are multiple variants, it is resulting in sstate objects which encode PN (they install into a PN subdir) but the sstate object reflects BPN. This leads to corruption between then and eventually, warnings from image builds like: WARNING: The license listed GPLv3 was not in the licenses collected for recipe gcc WARNING: The license listed GPL-3.0-with-GCC-exception was not in the licenses collected for recipe gcc WARNING: The license listed GPLv3 was not in the licenses collected for recipe gcc WARNING: The license listed NCSA was not in the licenses collected for recipe gcc-sanitizers WARNING: The license listed MIT was not in the licenses collected for recipe gcc-sanitizers WARNING: The license listed GPL-3.0-with-GCC-exception was not in the licenses collected for recipe gcc WARNING: The license listed GPLv3 was not in the licenses collected for recipe gcc WARNING: The license listed NCSA was not in the licenses collected for recipe gcc-sanitizers By referring to PN, as used by license.bbclass, this issue is resolved.

In http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=2d89cff42af2bb0049224bfaaebaa2b21966169f we added a workaround for dealing with lack of time sync between build machines and their users.

2016-01-29sstate: Improve handling of useradd dependenciesRichard Purdie1
useradd has sstate [depends] for both do_package and do_populate_sysroot yet the dependency validation code only covers do_package. Add coverage of populate_sysroot, else the order inversion that [depends] creates means unexpected installation of users of useradd.bbclass (e.g. avahi do_populate_sysroot) in cases where it shouldn't be (e.g. libnss-mdns -c packagedata). The code needs to move above the other populate_sysroot intercept code since there are specific cases we need to cover before that code. The result of this change is more optimal installation of sstate objects in common usage scenarios.

2016-01-19sstate: replace verbose manifest removal with a single countRoss Burton1
If there are lots of changes between the previous build and the build about to start bitbake will potentially print pages of: DEBUG: Stamp $BUILD/stamps/corei7-64-poky-linux/libdrm/2.4.66-r0 is not reachable, removing related manifests Instead of spamming the console with this list, write the list of manifests only to the debug log and simply write a count to the console. This way the user doesn't get spammed but still knows what is happening if bitbake appears to stall with heavy I/O. Signed-off-by: Ross Burton <ross.burton@intel.com>
2016-01-19sstate: Add packagedata to list of tasks not to recurseRichard Purdie1
If we "bitbake X -c packagedata" and the packagedata comes from sstate, we don't need any of the tasks dependencies. This is similar to the populate_lic case, we only care about the end result. Therefore short circuit the dependencies so packagedata doesn't pull in any other dependencies. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2015-12-14sstate: Ensure populate_lic dependencies are not followedRichard Purdie1
It was observed that do_fetch dependencies (e.g. subversion-native of tremor) were being installed even when sstate was available and hence no fetch was needed. This turned out to be due to the recursive nature of the rootfs dependencies which include populate_lic. We can explicitly whitelist these dependencies as being ones we don't need to follow when installing sstate (the code defaults to being paranoid).

2015-11-25sstate: Ensure siginfo and sig files are also touchedRichard Purdie1
Maintaining an sstate mirror is complicated at the moment as only the main sstate tgz files have their timestamp updated when they're used. This causes problems as the siginfo files can be removed from the server due to inactivity but the sstate fetch code tries to fetch them leading to confusing warnings and reduced debug capability. This change ensures we touch any sig/siginfo files present and should help ageing of the objects on sstate mirrors. It doesn't handle the intermediate task siginfo files but those are never fetched by the current sstate code so are an order of magnitude less problematic.

2015-11-24sstate: respect GPG_BIN and GPG_HOMERoss Burton1
The package feed signing code supports the user providing the path to the gpg binary and an alternative gpg 'home' (usually ~/.gnupg), which are useful for both deployment and QA purposes. Factor out the gpg command line construction to a function which can fetch both of these variables, and also use pipes.quote() to sanitise the arguments when used in a shell context.

2015-06-10sstate: Add eventhandler which cleans up stale recipe dataRichard Purdie1
"Incremental builds do not work well when renaming recipes or changing architecture" is a long standing issue which causes people considerable pain. We've struggled for a long time to come up with a way to generically address the problem. There are additional issues where removal of a layer caused data to continue to exist and additionally, changing DISTRO_FEATURES also caused problems in an existing TMPDIR. This patch attempts to address this by adding a mapping between stamp files and manifests. After parsing we can easily tell which stamp files are still reachable, if any manifest has a stamp that can no longer be reached, we can remove it. Since this code ties this to the sstate architecture list, it will not remove data from other than the current MACHINE (and its active architectures). It does not clean the sstate cache so if another build activates something which was cleaned, it should reinstall from sstate. We can also go one step further, depending on the setting of SSTATE_PRUNE_OBSOLETEWORKDIR, workdirs which are no longer active can also be removed. This avoids the buildup of many old copies of data in WORKDIR for example when versions are upgraded. The one thing which may surprise people with this change is if you remove a layer, data added by that layer will be "uninstalled" before the next build continues. I believe this is a feature and a good thing to do though. This code is safe with existing builds. If something isn't in the new index it simply isn't removed. Since changes to the sstate code trigger a rebuild, after this merges, we can assume the code will start to detect changes from that point onwards.

2014-09-29sstate: Change overlapping files warning to a fatal errorRichard Purdie1
When files overlap in the sysroot, something bad usually happened. We've had two independent cases recently where a couple of months after one of these warnings was shown, builds failed due to corruption. This change moves the warning to become a fatal error. The complaint I've had about this is that we need to tell the user what happened and more importantly how to recover from it. If we could recover from it, great but the trouble is we simply don't know what happened. As a compromise, we can document several of the possible scenarios in the error message. We don't normally go to this level of detail however in this case, I'm lacking other viable alternatives. I do believe it is important to stop as corruption occurs rather than letting the build contunue into territory that is not deterministic amongst other things. The complex message is followed by a simpler one in case the long message is too much for the user.

2014-09-17sstatesig/sstate: Add support for locked down sstate cache usageRichard Purdie1
I've been giving things some thought, specifically why sstate doesn't get used more and why we have people requesting external toolchains. I'm guessing the issue is that people don't like how often sstate can change and the lack of an easy way to lock it down. Locking it down is actually quite easy so patch implements some basics of how you can do this (for example to a specific toolchain). With an addition like this to local.conf (or wherever): SIGGEN_LOCKEDSIGS = "\ gcc-cross:do_populate_sysroot:a8d91b35b98e1494957a2ddaf4598956 \ eglibc:do_populate_sysroot:13e8c68553dc61f9d67564f13b9b2d67 \ eglibc:do_packagedata:bfca0db1782c719d373f8636282596ee \ gcc-cross:do_packagedata:4b601ff4f67601395ee49c46701122f6 \ " the code at the end of the email will force the hashes to those values for the recipes mentioned. The system would then find and use those specific objects from the sstate cache instead of trying to build anything. Obviously this is a little simplistic, you might need to put an override against this to only apply those revisions for a specific architecture for example. You'd also probably want to put code in the sstate hash validation code to ensure it really did install these from sstate since if it didn't you'd want to abort the build. This patch also implements support to add to bitbake -S which dumps the locked sstate checksums for each task into a ready prepared include file locked-sigs.inc (currently placed into cwd). There is a function, bb.parse.siggen.dump_lockedsigs() which can be called to trigger the same functionality from task space. A warning is added to sstate.bbclass through a call back into the siggen class to warn if objects are not used from the locked cache. The SIGGEN_ENFORCE_LOCKEDSIGS variable controls whether this is just a warning or a fatal error. A script is provided to generate sstate directory from a locked-sigs file.
