Pkgcore

--------------------------

- add TIMESTAMP header to binpkg Packages cache.

- mangle and add compatibility to source_repository handling to make
it play nice w/ past transgressions, and generate in a form portage
will like.

- fix traceback in binpkg installation

- fix pclone_cache hang

- suppress spurious slot shadowing test failure; occurs dependant on
GC behaviour, the complaint however doesn't matter (it false-negatives
on a mock object used for tests).


------------------------

------------------------

- pmaint regen now supports regenerating binary and install repository
caches.

- pkgcore now tracks and records the originating/source repository
when installing to the vdb.

- new pkg attribute; source_repository. This tracks where a package
originated from- primarily useful for binpkgs and vdb.
pquery --attr source_repository is how to access it from the CLI.

- pkg_config can now be invoked via:
pconfig package <target>

- splitdebug no longer runs if the pkg has been split already.

- arbitrary exceptions during merging/unmerging no longer stop the
merge/unmerge; a traceback is displayed instead.

- added initial profile inspection tool; pinspect profiles.

- pmaint copy arguments have changed; check the help, short version,
it's now sane.

- pkgcore now lives at googlecode; http://pkgcore.googlecode.com/

- large scale conversion of internals to argparse. Saner parsing namely,
although it's still a work in progress to make it pretty.

- man pages and docs in general have been converted to sphinx. Definite
improvement already, but more to come.

- pkgcore observer api's were heavily gutted and split into observer and
outputter. This should enable easier UX integration, while enabling
our next step towards parallelization.


--------------------------

--------------------------

- make use/useq/usev extremely obnoxious towards offending devs who use them
in global scope when they're not supposed to. Pretty much, I'm tired of
pkgcore being broken for being PMS compliant; as such I'm now pointing
users loud and clear at the offenders.

- fix traceback in user profile support (/etc/portage/profiles).


--------------------------

--------------------------

- Log an error, rather than throwing an exception when binpkg cache cannot
be updated. Needs refinement long term, but for average users, this is
preferable.

- loosen up pebuild a bit; choose the max version if slot/repo are all the
same. This allows pebuild dev-util/nano to choose 2.3.1 for example.

- tighten up econf implementation; ctarget/cbuild are now forced as early
arguments to configure to work around some misbehaviours in configure
scripts (broken scripts, but so it goes).

- tighten up ebuild environments variable handling- had a bleed through
of variable 'x' that was breaking mesa builds.

- yet another src_install fix for EAPI=4; this time ensuring the default
function is available.

- we now run bashrcs (profile and user) every phase to match portage
behaviour. If folks desire it, a patch making that optional would be
welcome.

- add support for /etc/portage/package.env and /etc/portage/env/. Note
that we only allow settings there to affect the bash environment- trying
to adjust FEATURES from those files isn't on the intended support list.

- use ${LIBDIR_${ABI}} for ccache/distcc pathways; gentoo bug 355283.

- profile interpretation of make.defaults now has access to variables
defined by its parents, per PMS.


--------------------------

--------------------------

- intercept and suppress exceptions from triggers unless the trigger
explicitly disables it.

- work around libmagic python bindings sucking and not always being
able to be used.

- fix 'default' support for src_install for EAPI=4.


--------------------------

--------------------------

- support for /etc/portage/make.profile; Please Do Not Use it, while
pkgcore is forced to support it, usage of it breaks most tools and is
bluntly lock-in (no reason to move it- it's the same, been in the same
place for a decade now). Duly warned.

- misc env/bug fixes for EMERGE_FROM to ensure compatibility.

- deploy eselect support via pinspect portageq

- added man page for pinspect

- added pmaint env-update

- expose /usr/local/* through PATH for ebuilds.
