`dxtbx.serialize.filename.resolve_path` fails on Windows for data collected on a POSIX platform about dxtbx HOT 4 OPEN

Actually it seems like this is delegated back to a Reader object

>>> iset.reader()
<dxtbx.format.FormatMultiImage.Reader object at 0x0000025952A310F0>
>>> iset.reader()._filename
'c:\\dls\\mx\\data\\nt30330\\nt30330-15\\VMXi-AB1698\\well_42\\images\\image_58766.nxs'

from dxtbx.

Ok, where it goes wrong is here:

On entry:

• path is '/dls/mx/data/nt30330/nt30330-15/VMXi-AB1698/well_42/images/image_58766.nxs'
• directory is 'c:\\Users\\fcx32934\\sw\\cctbx\\build\\dials_data\\dtpb_serial_processed'

Then os.path.join(directory, path) produces

'c:/dls/mx/data/nt30330/nt30330-15/VMXi-AB1698/well_42/images/image_58766.nxs'

Finally, os.path.abspath(path) escapes the path separators, resulting in

'c:\\dls\\mx\\data\\nt30330\\nt30330-15\\VMXi-AB1698\\well_42\\images\\image_58766.nxs'

from dxtbx.

Sorry, not quite right (I hate debugging on Windows).

It's just the action of os.path.abspath(path). The directory is irrelevant as the condition is False

In [5]: os.path.abspath(path)
Out[5]: 'c:\\dls\\mx\\data\\nt30330\\nt30330-15\\VMXi-AB1698\\well_42\\images\\image_58766.nxs'

from dxtbx.

What is the intended behaviour of resolve_path when it is passed a POSIX path on a Windows platform?
