# debugpy can also be invoked directly rather than via -m. In this case, the first
|
|
# entry on sys.path is the one added automatically by Python for the directory
|
|
# containing this file. This means that import debugpy will not work, since we need
|
|
# the parent directory of debugpy/ to be in sys.path, rather than debugpy/launcher/.
|
|
#
|
|
# The other issue is that many other absolute imports will break, because they
|
|
# will be resolved relative to debugpy/launcher/ - e.g. `import state` will then try
|
|
# to import debugpy/launcher/state.py.
|
|
#
|
|
# To fix both, we need to replace the automatically added entry such that it points
|
|
# at parent directory of debugpy/ instead of debugpy/launcher, import debugpy with that
|
|
# in sys.path, and then remove the first entry entry altogether, so that it doesn't
|
|
# affect any further imports we might do. For example, suppose the user did:
|
|
#
|
|
# python /foo/bar/debugpy/launcher ...
|
|
#
|
|
# At the beginning of this script, sys.path will contain "/foo/bar/debugpy/launcher"
|
|
# as the first entry. What we want is to replace it with "/foo/bar', then import
|
|
# debugpy with that in effect, and then remove the replaced entry before any more
|
|
# code runs. The imported debugpy module will remain in sys.modules, and thus all
|
|
# future imports of it or its submodules will resolve accordingly.
