Update to bmake-20200902

Browse Source 
Lots of code refactoring, simplification and cleanup.
Lots of new unit-tests providing much higher code coverage.
All courtesy of rillig at netbsd.

Other significant changes:

o new read-only variable .SHELL which provides the path of the shell
  used to run scripts (as defined by  the .SHELL target).

o variable parsing detects more errors.

o new debug option -dl: LINT mode, does the equivalent of := for all
  variable assignments so that file and line number are reported for
  variable parse errors.

A target is considered out-of-date if it does not exist, or if its

FILE DEPENDENCY SPECIFICATIONS
Dependency lines consist of one or more targets, an operator, and zero or
more sources. This creates a relationship where the targets ``depend''
on the sources and are usually created from them. The exact relationship
between the target and the source is determined by the operator that sep-
arates them. The three operators are as follows:
on the sources and are customarily created from them. A target is con-
sidered out-of-date if it does not exist, or if its modification time is
less than that of any of its sources. An out-of-date target will be re-
created, but not until all sources have been examined and themselves re-
created as needed. Three operators may be used:
: A target is considered out-of-date if its modification time is less
than those of any of its sources. Sources for a target accumulate
over dependency lines when this operator is used. The target is
removed if bmake is interrupted.
: Many dependency lines may name this target but only one may have
attached shell commands. All sources named in all dependency lines
are considered together, and if needed the attached shell commands
are run to create or re-create the target. If bmake is inter-
rupted, the target is removed.
! Targets are always re-created, but not until all sources have been
examined and re-created as necessary. Sources for a target accumu-
late over dependency lines when this operator is used. The target
is removed if bmake is interrupted.
! The same, but the target is always re-created whether or not it is
out of date.
:: If no sources are specified, the target is always re-created. Oth-
erwise, a target is considered out-of-date if any of its sources
has been modified more recently than the target. Sources for a
target do not accumulate over dependency lines when this operator
is used. The target will not be removed if bmake is interrupted.
:: Any dependency line may have attached shell commands, but each one
is handled independently: its sources are considered and the
attached shell commands are run if the target is out of date with
respect to (only) those sources. Thus, different groups of the
attached shell commands may be run depending on the circumstances.
Furthermore, unlike :, for dependency lines with no sources, the
attached shell commands are always run. Also unlike :, the target
will not be removed if bmake is interrupted.
All dependency lines mentioning a particular target must use the same
operator.

This creates a relationship where the targets
.Dq depend
on the sources
and are usually created from them.
The exact relationship between the target and the source is determined
by the operator that separates them.
The three operators are as follows:
and are customarily created from them.
A target is considered out-of-date if it does not exist, or if its
modification time is less than that of any of its sources.
An out-of-date target will be re-created, but not until all sources
have been examined and themselves re-created as needed.
Three operators may be used:

.It Ic \&:
A target is considered out-of-date if its modification time is less than
those of any of its sources.

is used.

The same, but the target is always re-created whether or not it is out
of date.
.It Ic \&::
If no sources are specified, the target is always re-created.
Otherwise, a target is considered out-of-date if any of its sources has
been modified more recently than the target.
Sources for a target do not accumulate over dependency lines when this
operator is used.
The target will not be removed if
Any dependency line may have attached shell commands, but each one
is handled independently: its sources are considered and the attached
shell commands are run if the target is out of date with respect to
(only) those sources.
Thus, different groups of the attached shell commands may be run
depending on the circumstances.
Furthermore, unlike
.Ic \&:,
for dependency lines with no sources, the attached shell
commands are always run.
Also unlike

2020-08-26 Simon J Gerraty <sjg@beast.crufty.net>
* dirdeps.mk: ensure we cannot confuse a static cache for dynamic
(even more rare that use of static cache is playing clever tricks
with it)
2020-08-16 Simon J Gerraty <sjg@beast.crufty.net>
* dirdeps-cache-update.mk: allow
MK_STATIC_DIRDEPS_CACHE_UPDATE_IMMEDIATE to control when we
actually update STATIC_DIRDEPS_CACHE.
* stage-install.sh: create dest directory if needed
before running install(1)
2020-08-10 Simon J Gerraty <sjg@beast.crufty.net>
* dirdeps-targets.mk: include Makefile.dirdeps.options
* dirdeps.mk: use _TARGETS if defined for DIRDEPS_CACHE
2020-08-09 Simon J Gerraty <sjg@beast.crufty.net>
* dirdeps.mk: default BUILD_DIRDEPS_MAKEFILE to empty
* dirdeps-cache-update.mk: building parallel cache update
under the context of dirdeps-cached would be ideal, but
is problematic, so it runs as a sibling.
Use cache-built target to ensure we wait for it to complete if
necessary.
2020-08-06 Simon J Gerraty <sjg@beast.crufty.net>
* install-mk (MK_VERSION): 20200806
* dirdeps-options: allow TARGET_SPEC to affect option values.
Use DIRDEPS_OPTIONS_QUALIFIER_LIST before using bare MK_*
* dirdeps-targets.mk: check for MK_STATIC_DIRDEPS_CACHE defined
before looking for STATIC_DIRDEPS_CACHE
2020-08-05 Simon J Gerraty <sjg@beast.crufty.net>
* host-target.mk: Darwin use MACHINE for HOST_ARCH too
* dirdeps-options.mk: improve debug output
2020-07-22 Simon J Gerraty <sjg@beast.crufty.net>
* dirdeps.mk: set and export DYNAMIC_DIRDEPS_CACHE
for use by dirdeps-cache-update.mk
* dirdeps-targets.mk: set and export STATIC_DIRDEPS_CACHE
for use by dirdeps-cache-update.mk even if we don't use it.
* dirdeps-cache-update.mk: we only need worry about the background
update case, with the above, the update from DIRDEPS_CACHE is
simple.
* meta2deps.py: R 1234 . is not interesting
2020-07-20 Simon J Gerraty <sjg@beast.crufty.net>
* sys.mk: default MK_STATIC_DIRDEPS_CACHE from MK_DIRDEPS_CACHE
* dirdeps-options.mk: do not :tu DIRDEPS_OPTIONS
allows use of lower case for pseudo options.
* dirdeps-cache-update.mk: magic to deal with STATIC_DIRDEPS_CACHE
2020-07-18 Simon J Gerraty <sjg@beast.crufty.net>
* dirdeps-targets.mk: Look for Makefile.dirdeps.cache
which allows us to have a static cache for expensive targets.
Use -DWITHOUT_STATIC_DIRDEPS_CACHE -DWITH_DIRDEPS_CACHE
to regenerate the dirdeps.cache it is a copy of.

* dirdeps.mk (DIRDEP_LOADAVG_REPORT): make it easy to record
load averages at intervals during build.
2020-07-15 Simon J Gerraty <sjg@beast.crufty.net>
* install-mk (MK_VERSION): 20200715
* dirdeps.mk: tweak Checking line to make matching Finished
lines for post-build analysis easier.
* meta.autodep.mk: use !defined(WITHOUT_META_STATS)
* progs.mk: avoid prog.mk outputting multiple Finished lines
2020-07-11 Simon J Gerraty <sjg@beast.crufty.net>

generate a DIRDEPS.${.TARGET} list for other purposes

# This makefile deals with the updating of STATIC_DIRDEPS_CACHE.
# Some targets are so huge that computing dirdeps takes a significant
# amount of time. For such targets a STATIC_DIRDEPS_CACHE can make
# sense.
#
# If the target is represented by targets/pseudo/production
# it's normal DIRDEPS would be in
# targets/pseudo/production/Makefile.depend
# and STATIC_DIRDEPS_CACHE would be
# targets/pseudo/production/Makefile.dirdeps.cache
# which is simply initialized by copying dirdeps.cache.production
# from $OBJTOP
#
# When dirdeps-targets.mk is initializing DIRDEPS it will look for
# Makefile.dirdeps.cache and unless told not to
# (MK_STATIC_DIRDEPS_CACHE=no) will use it as DIRDEPS_CACHE.
#
# If MK_STATIC_DIRDEPS_CACHE_UPDATE is "yes", then this makefile
# comes into play.
#
# We usually get included from local.dirdeps.mk
# as well as Makefile.depend of RELDIR with a static Makefile.dirdeps.cache
#
# If we see that STATIC_DIRDEPS_CACHE is in use, we need to hook a
# cache-update target into the build to regenerate dirdeps.cache
# in parallel with the rest of the build.
# If MK_STATIC_DIRDEPS_CACHE_UPDATE_IMMEDIATE is "yes" we update
# STATIC_DIRDEPS_CACHE as soon as the update is ready,
# otherwise it will be done at the end of the build.
#
# If STATIC_DIRDEPS_CACHE is not in use, but a DIRDEPS_CACHE is,
# then we need do nothing except export STATIC_DIRDEPS_CACHE and
# DYNAMIC_DIRDEPS_CACHE for use when we are include during the visit
# to the ultimate target (targets/pseudo/production).
#
# Regardless of which happens, when included at .MAKE.LEVEL > 0
# for a target other than cache-update we simply copy
# DYNAMIC_DIRDEPS_CACHE to STATIC_DIRDEPS_CACHE with some optional
# filtering.
#
# If we are included for the target cache-update we take care of
# running dirdeps.mk again to generate the DYNAMIC_DIRDEPS_CACHE.
