Cannot open GZip compressed file

[karlwessel]

When I try to open a GZipped file (.fits.gz-extension) I get the following error message

julia> using FITSIO

julia> FITS("pyobs-20210305-0228-e00.fits.gz")
ERROR: CFITSIO has encountered an error while processing pyobs-20210305-0228-e00.fits.gz. Error code 113: could not allocate memory
Detailed error message follows: 
Failed to reduce size of allocated memory (compress_open)
failed to find or open the following file: (ffopen)

Stacktrace:

Opening the file with astropy works fine.

If you want I can also upload the fits file where it does not work.

This is the state of my environment:

(jl_BYqwHQ) pkg> st
Status `/tmp/jl_BYqwHQ/Project.toml`
  [525bcba6] FITSIO v0.16.7

It works for me with this FITS file, compressed with gzip:

julia> using FITSIO

julia> FITS("WFPC2u5780205r_c0fx.fits.gz")
File: WFPC2u5780205r_c0fx.fits.gz
Mode: "r" (read-only)
HDUs: Num  Name                   Type

      2    u5780205r_cvt.c0h.tab  ASCIITable  

But 99% this is an upstream issue with CFITSIO, we don't do anything special to open compressed files (differently from Astropy, see #135)

Thanks for the quick check!

For that one it works for me to. It also works if I create a gzipped FITS file with astropy.

Don't know whats wrong with that file.

For now I will just use GZip.jl to decompress the file it into a temporary file beforehand.

I will close this, since it seems to be some special problem with my file. And maybe it could be solved by FileIOs handling of compressed files...
