Comment 4 for bug 1537721

Yep, I analyzed the bug a bit.
Glance does not send the size to the swift, so by default glance_store splits the file to 200 Mb chunks.
But it seems not linked to the issue root cause: radosgw create doesn't delete 0-length chunk when glance_store generated ZeroSize exception. I tested this with Swift installation and it works well - no zero-length chunk.
I digged into requests library without no success (but still analyzing).
I am wondering if it is RadosGW issue (it doesn't expect ZeroLength exception) or Apache issue.
