Paul Eggleton 2c14be3507 gen-lockedsig-cache: fix bad destination path joining
When copying the sstate-cache into the extensible SDK, if the source
path had a trailing / and the destination path did not, there would be a
missing / between the path and the subdirectory name, and you'd end up
with subdirectories like "sstate-cacheCentOS-6.7". There are functions
in os.path for this sort of thing so let's just use them and avoid the
problem.

Paul Eggleton 477fa84390 gen-lockedsig-cache: copy correct native sstate into ext SDK
When constructing the sstate-cache directory for the extensible SDK,
we were copying in any matching native sstate packages, and as the
signature doesn't actually change when the distro changes (since
NATIVELSBSTRING is just a path separator for the artifacts and is not
part of the signature) we ended up copying duplicated packages when the
distro changed e.g. upon host distro upgrade. Only search in the
NATIVELSBSTRING-named subdirectory for native packages and the issue
goes away.

Fixes [YOCTO #8885].

Paul Eggleton 5febb1dc5b scripts/gen-lockedsig-cache: fix race with temp file creation
As part of populating the sstate-cache with an artifact (.tgz file) we
create a temp file and then atomically move it to the final name. Due to
the glob used in this script such temp files were being matched, and
between the time they were matched and the time the script started
copying files, the temp file may have vanished.

This fixes random "No such file or directory" failures building the
extensible SDK on build setups where the sstate-cache directory is shared
amongst multiple build machines.

Randy Witt 67c1d2eeb7 gen-lockedsig-cache: Allow cross-filesystem copies.
Since this previously always tried to use hardlinks you couldn't have
the source and destination be on different devices. This change allows
for that and also prevents failure in situations where the files already
existed.

Richard Purdie c5cc4993f0 sstatesig/sstate: Add support for locked down sstate cache usage
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.
