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

# As of 2020-08-09, the code in Var_Export is shared between the .export
|
|
# directive and the .MAKE.EXPORTED variable. This leads to non-obvious
|
|
# behavior for certain variable assignments.
|
|
|
|
-env= make-exported-value-env
|
|
-literal= make-exported-value-literal
|
|
UT_VAR= ${UNEXPANDED}
|
|
|
|
# Before 2020-10-03, the following line took the code path of .export-env,
|
|
# which was surprising behavior. Since 2020-10-03 this line tries to
|
|
# export the variable named "-env", but that is rejected because the
|
|
# variable name starts with a hyphen.
|
|
.MAKE.EXPORTED= -env
|
|
|
|
# Before 2020-10-03, if the value of .MAKE.EXPORTED started with "-literal",
|
|
# make behaved like a mixture of .export-literal and a regular .export.
|
|
#
|
|
# Since 2020-10-03, the "variable" named "-literal" is not exported anymore,
|
|
# it is just ignored since its name starts with '-'.
|
|
.MAKE.EXPORTED= -literal UT_VAR

all:

@env | sort | egrep '^UT_|make-exported-value' || true
