Description
CFITSIO is not able to open a fits file if there is a blank character in the path name. This situation happens when one segment of the dataId contains a blank. For instance some early CFHT data have an OBJECT entry in the fits header which is equal to "D3 (Groth)", when ingesting the image, the blank is kept in the butler directory structure and CFITSIO is returning and error status = 104 when trying to open the file.

I tried to open the file using the fitsio python module and it returned an error. The same file (with the blank in the path name) can be opened by astropy. So it can be considered as a bug in cfitsio. I don't know what is best: correct cfitsio or try to find a workaround in DM ?

I'll try to remember to sanitize filenames after template expansion in gen3 butler.
Team → DAX since this is a Butler/persistence problem. Fritz Mueller, if you need Pipelines to futz with cfitsio, give us a shout.
Is the correct filename getting to cfitsio? That is, is this a bug in cfitsio or our system?
