The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.
Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure. Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.
Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

# OVERALL: Nemesis now supports an "--enable-yield=..." configure
option for better performance/behavior when oversubscribing
processes to cores. Some form of this option is enabled by default
on Linux, Darwin, and systems that support sched_yield().
# OVERALL: Added support for Intel Many Integrated Core (MIC)
architecture: shared memory, TCP/IP, and SCIF based communication.
# OVERALL: Added support for IBM BG/Q architecture. Thanks to IBM
for the contribution.
# MPI-3: const support has been added to mpi.h, although it is
disabled by default. It can be enabled on a per-translation unit
basis with "#define MPICH2_CONST const".
# MPI-3: Added support for MPIX_Type_create_hindexed_block.
# MPI-3: The new MPI-3 nonblocking collective functions are now
available as "MPIX_" functions (e.g., "MPIX_Ibcast").
# MPI-3: The new MPI-3 neighborhood collective routines are now available as
"MPIX_" functions (e.g., "MPIX_Neighbor_allgather").
# MPI-3: The new MPI-3 MPI_Comm_split_type function is now available
as an "MPIX_" function.
# MPI-3: The new MPI-3 tools interface is now available as "MPIX_T_"
functions. This is a beta implementation right now with several
limitations, including no support for multithreading. Several
performance variables related to CH3's message matching are exposed
through this interface.
# MPI-3: The new MPI-3 matched probe functionality is supported via
the new routines MPIX_Mprobe, MPIX_Improbe, MPIX_Mrecv, and
MPIX_Imrecv.
# MPI-3: The new MPI-3 nonblocking communicator duplication routine,
MPIX_Comm_idup, is now supported. It will only work for
single-threaded programs at this time.
# MPI-3: MPIX_Comm_reenable_anysource support
# MPI-3: Native MPIX_Comm_create_group support (updated version of
the prior MPIX_Group_comm_create routine).
# MPI-3: MPI_Intercomm_create's internal communication no longer interferes
with point-to-point communication, even if point-to-point operations on the
parent communicator use the same tag or MPI_ANY_TAG.
# MPI-3: Eliminated the possibility of interference between
MPI_Intercomm_create and point-to-point messaging operations.
# Build system: Completely revamped build system to rely fully on
autotools. Parallel builds ("make -j8" and similar) are now supported.
# Build system: rename "./maint/updatefiles" --> "./autogen.sh" and
"configure.in" --> "configure.ac"
# JUMPSHOT: Improvements to Jumpshot to handle thousands of
timelines, including performance improvements to slog2 in such
cases.
# JUMPSHOT: Added navigation support to locate chosen drawable's ends
when viewport has been scrolled far from the drawable.
# PM/PMI: Added support for memory binding policies.
# PM/PMI: Various improvements to the process binding support in
Hydra. Several new pre-defined binding options are provided.
# PM/PMI: Upgraded to hwloc-1.5
# PM/PMI: Several improvements to PBS support to natively use the PBS
launcher.
# Several other minor bug fixes, memory leak fixes, and code cleanup.

# OVERALL: MPICH2 is now fully compliant with the CIFTS FTB standard
MPI events (based on the draft standard).

RMA operations.
# OVERALL: Performance improvements for Group_translate_ranks.
# COLLECTIVES: Collective algorithm selection thresholds can now be controlled
at runtime via environment variables.

Changes in 1.3
# OVERALL: Initial support for fine-grained threading in
ch3:nemesis:tcp.
# OVERALL: Support for Asynchronous Communication Progress.
# OVERALL: The ssm and shm channels have been removed.
# OVERALL: Checkpoint/restart support using BLCR.
# OVERALL: Improved tolerance to process and communication failures
when error handler is set to MPI_ERRORS_RETURN. If a communication
operation fails (e.g., due to a process failure) MPICH2 will return
an error, and further communication to that process is not
possible. However, communication with other processes will still
proceed normally. Note, however, that the behavior collective
operations on communicators containing the failed process is
undefined, and may give incorrect results or hang some processes.
# OVERALL: Experimental support for inter-library dependencies.
# PM/PMI: Hydra is now the default process management framework
replacing MPD.
# PM/PMI: Added dynamic process support for Hydra.
# PM/PMI: Added support for LSF, SGE and POE in Hydra.
# PM/PMI: Added support for CPU and memory/cache topology aware
process-core binding.
# DEBUGGER: Improved support and bug fixes in the Totalview support.
# Build system: Replaced F90/F90FLAGS by FC/FCFLAGS. F90/F90FLAGS are
not longer supported in the configure.
# Multi-compiler support: On systems where C compiler that is used to
build mpich2 libraries supports multiple weak symbols and multiple aliases,
the Fortran binding built in the mpich2 libraries can handle different
Fortran compilers (than the one used to build mpich2). Details in README.
# Several other minor bug fixes, memory leak fixes, and code cleanup.

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
MPICH2 is an all-new implementation of MPI from the group at Argonne
National Laboratory. It shares many goals with the original MPICH but
no actual code. It is a portable, high-performance implementation of
the entire MPI-2 standard. This release has all MPI-2 functions and
features required by the standard with the exception of support for the
"external32" portable I/O format.
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
