The shared CFG library overrides ControlFlowNode.toString() as 'final'
(shared/controlflow/codeql/controlflow/Cfg.qll:1217), so the legacy
'ControlFlowNode for X' prefix is gone — the new toString returns just
'X' for normal nodes and 'After X' for after-nodes. This produces a
large cosmetic diff in test expected files with no semantic change.
Mass-rebless 78 .expected files whose actual output differs from the
checked-in expected only by this rename. Each file was verified to be
identical after normalising 'ControlFlowNode for ' and 'After ' away
from both sides.

I'm beginning to realise why I didn't do the `toString` overriding way
back when. Thankfully, now that all of our tests are in the same place,
this is actually not a terrible ordeal.
I reckon this is due to the Python 3 version used by the Python 2 tests
is different from 3.12, so even with --lang=3 the tests are still using
an incompatible version :(
since
- Python 3 is ok from 3.7 onwards
- support for Python 3.6 was just dropped
- we do not actually know the minor version of the analysed code
(only of the extractor)
For syntax errors, we simply report the major version.
For unused imports, we were getting a result for `typing.py` when run under
Python 3.7.3. To prevent this import from being considered, I've set the maximum
import depth to `0`.
Fixes#1969.
The points-to analysis does not know that the assignment `input = raw_input`
cannot fail under Python 2, and so there are two possible values that `input`
could point-to after exiting the exception handler: the built-in `input`, or the
built-in `raw_input`. In the latter case we do not want to report the alert, and
so adding a check that the given function does not point-to the built-in
`raw_input` suffices.
Due to internal PR#35123 we now actually run the tests under
`python/ql/test/2/...`
Since we haven't done this in a while, test output has changed a bit. These
changes look perfectly fine.
