TASKFILE_DIR doesn't resolve with respect to the task file its referenced in when in an included task file

[OldTechNeck]

Description

Overview

I have a three level Taskfile inclusion hierarchy. When setting a variable in a "middle-level" task file and executing a task in the third level, the TASKFILE_DIR value only evaluates to the third level.

I've searched and see a number of issues related to variable resolution and even tried to grok a couple of the open issues but I'm not sure if this is captured from this angle so just in case I'm doing it here. Feel free to delete if this is just noise. Or, if it will be "fixed" (maybe too strong a term) in an upcoming release please let me know.

Details

TASKFILE_DIR used in a task file doesn't seem to be evaluated at the time/scope the file is included, but rather at the time that the final task, however deep in include levels a task is run.

I'll show the files below. To illustrate the problem I run:

task level1:level2:print-test

and I get the following output:

TEST_ROOT = /tmp/root/level1/level2
VTEST_ROOT = /tmp/root/level1/level2
TEST_LEVEL1 = /tmp/root/level1/level2
VTEST_LEVEL1 = /tmp/root/level1/level2
TEST_LEVEL2 = /tmp/root/level1/level2
VTEST_LEVEL2 = /tmp/root/level1/level2

When, at least the way I read the docs and also the way I would expect it to work, the output should be:

TEST_ROOT = /tmp/root
VTEST_ROOT = /tmp/root
TEST_LEVEL1 = /tmp/root/level1
VTEST_LEVEL1 = /tmp/root/level1
TEST_LEVEL2 = /tmp/root/level1/level2
VTEST_LEVEL2 = /tmp/root/level1/level2
