sys.path does not include subdirectory

[achalddave]

In python and ipython, when running a script from a parent directory (e.g. python foo/bar.py), sys.path contains the script's immediate parent directory. However, this does not seem to be the case for ptpython.

I thought this might be related to davidhalter/jedi#1148 and #246 , but downgrading to jedi <0.12 (0.11.1 specifically) does not fix the issue.

~/tmp/ptpython-path-debug ~ mkdir foo
~/tmp/ptpython-path-debug ~ cat <<EOF >foo/bar.py
import sys
print(sys.path)
EOF

~/tmp/ptpython-path-debug ~ python foo/bar.py
['/home/achald/tmp/ptpython-path-debug/foo', <global_paths>]

~/tmp/ptpython-path-debug ~ ipython foo/bar.py
['/home/achald/tmp/ptpython-path-debug/foo', '', <global_paths>]

~/tmp/ptpython-path-debug ~ ptpython foo/bar.py
['', <global_paths>]

Note the lack of /home/achald/tmp/ptpython-path-debug/foo in the last sys.path.

Hi @achalddave,

Can you try to upgrade to the latest ptpython version and try again? I just pushed a new version to pypi.
There was indeed a bug in Jedi, and now we have a workaround that ensures that the current directory is always in sys.path.

[achalddave]

I just upgraded and tried, and the issue still seems to exist. Note that ptpython does always add the current directory in sys.path (although I'm unsure if that's expected or a bug: python by default only adds the directory that the file is in, while ipython adds the current directory and the directory that the file is in), but fails to add the directory the file is in.

That is, the following things are always in the path for each of the interpreters:

python <script>: parent directory of <script>
ipython <script>: parent directory of <script>, current working directory
ptpython <script>: current working directory (after jedi bug fix)

I believe a new Jedi version has been released. Can you try again upgrading both ptpython and Jedi to the latest version?

[achalddave]

Just upgraded both. Still seeing the same issue.
python

~/t/ptpython-debug ~ py foo/bar.py
['/home/achald/tmp/ptpython-debug/foo', <global paths>]

ptpython

~/t/ptpython-debug ~ ptpy foo/bar.py
['', <global paths>]

@achalddave, Are you sure that the same environment is used for both pip and ptpython?

Can you run the pip-show commands using the python -m pip show ptpython syntax, and start ptpython by running python -m ptpython? I wonder if that shows the same results.

[achalddave]

Yeah they should be the same environment. Does this issue not show up for you? I can debug this more on my end, if you're not seeing the issue (maybe with a separate python install or try removing and re-installing).
