Quite a lot of churn on style, but lots of
good work refactoring complicated functions
and lots more unit-tests.
Thanks mostly to rillig at NetBSD
Some interesting entries from ChangeLog
o .MAKE.{UID,GID} represent uid and gid running make.
o allow env var MAKE_OBJDIR_CHECK_WRITABLE=no to skip writable
checks in InitObjdir. Explicit .OBJDIR target always allows
read-only directory.
o add more unit tests for META MODE

# Tests for the effective RunFlags of a shell command (run/skip, echo/silent,
|
|
# error check, trace), which are controlled by 12 different switches. These
|
|
# switches interact in various non-obvious ways. To analyze the interactions,
|
|
# this test runs each possible combination of these switches, for now.
|
|
#
|
|
# As soon as an interaction of switches is identified as obvious and expected,
|
|
# this particular interaction may be removed from the test, to focus on the
|
|
# remaining ones.
