Unfortunately, .pyc files can be generated in meta/lib/oe which corrupt the pseudo
database so we need to extend the ignore list to cover this as well.

This is a pretty big change to the way pseudo operates when used in OpenEmbedded.
Normally, pseudo monitors and logs (adds to its database) any file created or
modified whilst in a fakeroot environment. There are large numbers of files
we simply don't care about the permissions of whilst in that fakeroot context,
for example ${S}, ${B}, ${T}, ${SSTATE_DIR}, the central sstate control
directories,
This change uses new functionality in pseudo to ignore these directory trees,
resulting in a cleaner database with less chance of "stray" mismatches if files
are modified outside pseudo context. It also should reduce some overhead from
pseudo as the interprocess round trip to the server is avoided.
There is a possible complication where some existing recipe may break, for
example, we found a recipe which was writing to "${B}/install" for
"make install" in do_install and since we listed ${B} as not to be tracked,
there were errors trying to chown root for files in this location.
This patch fixes a few corner cases in OE-Core when used with this new
ignore list:
* The archiver directory matched a "${WORKDIR}/deploy*" pattern so was renamed
to something else since that directory does need its root permissions
* The ${S} and ${B} ignoring is conditional on them being different to ${WORKDIR}
* package_write_* task output (the debs/rpms/ipks) are now owned by the build
user so we don't want the file ownership information in the hashequiv outhash
calculation even if they are built under pseudo.
* The fontcache postinstall intercept is run under qemu outside of pseudo context
so delete files it may delete up front where pseudo can see this.
* SSTATE_DIR is in PSEUDO_PATHS_IGNORE, which is in FAKEROOTENV which is cached
by bitbake. We therefore need to trigger reparsing if this changes, which means
SSTATE_DIR can be in BB_HASHBASE_WHITELIST but not BB_HASHCONFIG_WHITELIST.
Rework the variables to handle this. This otherwise breaks some of our sstate
tests in oe-selftest.
* Ignore the temp directory wic uses for rebuilding rootfs.

* similar to kernel-artifact-names for other recipes/bbclasses which

* bitbake.conf: move IMAGE_BASENAME, IMAGE_VERSION_SUFFIX, IMAGE_NAME,

image_types.bbclass and meta/recipes-core/images/build-appliance-image_15.0.0.bb
but if it's needed by some recipe which isn't itself an image, then
it's useful in bitbake.conf, e.g. we have a recipe for creating
VirtualBox appliances which combines .wic.vmdk with .ovf file to
create .zip with appliance, but for that we need the filename of
.wic.vmdk which now contains IMAGE_NAME_SUFFIX

When the PR service is enabled a number of small changes may happen
to variables. In the do_package step a call to package_get_auto_pr
will end up setting PRAUTO and modifying PKGV (if AUTOINC is there).
PRAUTO is then used by EXTENDPRAUTO, which is then used to generate
PKGR.
Since this behavior typically happens BEFORE the BB_UNIHASH is
calculated for do_package, we need a way to defer the expansion
until after we have the unihash value.
Writing out the pkgdata files w/o AUTOPR and PKGV (AUTOINC) expanded
to placeholder values is the easiest way to deal with this. All other
variables are expanded as expected.
In the next task, typically do_packagedata, we will then use the
UNIHASH from the do_package to get the PR (AUTOPR) as well as
generate the AUTOINC replacement value (now PRSERV_PV_AUTOINC).
The do_packagedata then translates the placeholders to the final values
when copying the data from pkgdata to pkgdata-pdata-input.
Also update the prservice test case. With unihash, just changing the
do_package (via a _append) will not change the PR. So write the date
to a specific file that is incorporated into the unihash to ensure it
is always different for the test. Various assert messages were also
updated to make it easier to figure out where/why a problem occured.

The number of threads used, and the amount of memory allowed
to be used, should not affect sstate signatures, as they
don't affect the outcome of the compression if xz operates
in multi-threaded mode [1].
Otherwise, it becomes impossible to re-use sstate from
automated builders on developer's machines (as the former
might execute bitbake with certain constraints different
compared to developer's machines).
This is in particular a problem with the opkg package writing
backend, as the OPKGBUILDCMD depends on XZ_DEFAULTS. Without
the vardepexclude, there is no re-use possible of the
package_write_ipk sstate.
Whitelist the maximum number of threads and the memory limit
given assumptions outlined in [2] below.
Signed-off-by: André Draszik <git@andred.net>
[1] When starting out in multi-threaded mode, the output is always
deterministic, as even if xz scales down to single-threaded later,
the archives are still split into blocks and size information is
still added, thus keeping them compatible with multi-threaded mode.
Also, when starting out in multi-threaded mode, xz never scales
down the compression level to accomodate memory usage restrictions,
it just scales down the number of threads and errors out if it
can not accomodate the memory limit.
[2] Assumptions
* We only support multi-threaded mode (threads >= 2), builds
should not try to use xz in single-threaded mode
* The thread limit should be set via XZ_THREADS, not via
modifying XZ_DEFAULTS or XZ_OPTS, or any other way
* The thread limit should not be set to xz's magic value
zero (0), as that will lead to single-threaded mode on
single-core systems.

xz archives can be non-deterministic / non-reproducible:
a) archives are created differently in single- vs
multi-threaded modes
b) xz will scale down the compression level so as to
be try to work within any memory limit given to
it when operating in single-threaded mode
This means that due to bitbake's default of using as many
threads as there are cores in the system, files compressed
with xz will be different if built on a multi-core system
compared to single-core systems. They will also potentially
be different if built on single-core systems with different
amounts of physical memory, due to bitbake's default of
limiting xz's memory consumption.
Force multi-threaded operation by default, even on single-core
systems, so as to ensure archives are created in the same
way in all cases.

By default, we won't copy and strip static libraries. However, this
functionality can be useful in some cases where people are doing
development on the target, and don't generally want the larger debug
capable static libraries. To enable the new functionality set:
PACKAGE_DEBUG_STATIC_SPLIT = '1'
Add a new function splitstaticdebuginfo. Thus function will copy the
unmodified static library into the specific debug directory location.
By keeping an unmodified version, it is possible for a user trying
to debug something to use -L /usr/lib/.debug-static and their existing
build commands to switch from stripped to full debug versions.
The PACKAGE_DEBUG_SPLIT_STYLE will select between two different
approaches, /usr/lib/debug-static or <path>/.debug-static.
Additionally you can now choose to strip static libraries to conserve
space. If either 'PACKAGE_DEBUG_STATIC_SPLIT' or 'PACKAGE_STRIP_STATIC'
is set to 1, the static library will be stripped. (This is not on by
default, as it could make diagnosing static library usage difficult in
some cases.)
Add to insane.bbclass a skip to the staticdev warning for the specific
-dbg package versions.

Permanently adds the -src source package to ${PACKAGES} instead of
relying on creating it dynamically at packaging time. The source package
is now defined in bitbake.conf, just like -dev and -dbg packages.
For compatibility, the -src package is still added dynamically if it was
missing, since some recipes have a tendency to completely override
PACKAGES and do so without manually adding back the -src package.
This allows RDEPENDS on the -src packages, which wasn't previously

The previous ccache.bbclass has the following problems:
- It uses host's ccache for native recipes, but this may not work on some
hosts, for example, it nerver works on my Ubuntu 14.04.4, there are always
build failures (m4-native failed at do_configure, and others will also be
failed if I disable CCACHE for m4-native)
- native/nativesdk/cross/crosssdk recipes use host's ccache, but target uses
ccache-native, this may confuse user.
- The target recipes may use both host's ccache and ccache-native, this may
cause unexpected problems and be hard to debug. This is because ccache-native is
in SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS, so ccache-native may not be present when
rebuild target recipes, and then it would use hosttools/ccache, but the
previous ccache files were generated by ccache-native.
- Target recipes can't use ccache when no ccache is installed on the host:
CCACHE = "${@bb.utils.which(d.getVar('PATH'), 'ccache') and 'ccache '}"
After refactored:
All types recipes (native, target and others) will use ccache-native except
ccache-native itself, host's cache won't be used any more. It is more
reliable now, which will work everywhere when ccache-native can be built.
And now we need use "CCACHE_DISABLE = '1'" to disable ccache for the recipe
rather than "CCACHE = ''" since we set CCACHE in anonymous function, and
d.getVar('CCACHE') works after "CCACHE ??=" which is set in bitbake.conf, so we
can't check whether CCACHE is set or not in anonymous function since it is
always set. Use CCACHE_DISABLE to disable it would be more clear.
