* Add build-time option to suffix library names sent to dlopenTim Burke2021-10-261-2/+2
| | | | | | This is useful when repacking libraries for python wheels, for example. Change-Id: Ie7b36584de5054c14a9b77d87a5c5fa5cc7a3719
* Add Phazr.IO libphazr backend to liberasurecodeJim Cheung2017-02-281-1/+2
| | | | | | | | | | | | | | | | Currently, there are several implementations of erasure codes that are available within OpenStack Swift. Most, if not all, of which are based on the Reed Solomon coding algorithm. Phazr.IO’s Erasure Coding technology uses a patented algorithm which are significantly more efficient and improves the speed of coding, decoding and reconstruction. In addition, Phazr.IO Erasure Code use a non-systematic algorithm which provides data protection at rest and in transport without the need to use encryption. Please contact support@phazr.io for more info on our technology. Change-Id: I4e40d02a8951e38409ad3c604c5dd6f050fa7ea0
