-h option not working for decompression

[yunhua-deng]

zfp -i datafile -z datafile.zfp <options> works perfectly
zfp -z datafile.zfp -o datafile.raw <options> works perfectly
zfp -i datafile -z datafile.zfp -o datafile.raw <options> works perfectly

but,
zfp -i datafile -z datafile.zfp <options> -h works
zfp -z datafile.zfp -o datafile.raw -h doesn't work and reports array size must be nonzero

What is the correct way to use -h option in order to avoid typing <options> in decompression?

PS: datafile is around several MB in byte size

I confirm that header support is broken in zfp 0.5.4. In this version, we added a test to ensure that any user-specified array dimensions are nonzero for compression, which is incorrectly triggered when decompressing using a header. We will push a fix in the next 24 hours.

@yunhua-deng, I have pushed a fix on the develop branch. Can you please verify that it addresses your issue?

[yunhua-deng]

After applying the fix, zfp -i datafile -z datafile.zfp <options> -h & zfp -z datafile.zfp -o datafile.raw -h works perfectly! Please feel free to close the issue once the fix is in the master.

This fix has been added to zfp 0.5.5 and has been pushed to master. I am closing the issue.
