- update to 1.6.2:
* Allow the writing of fragments with the legacy, non-standard CRC-32.
This is intended to smooth upgrades from liberasurecode 1.5.0 and
earlier in a system with multiple readers and writers.
See https://bugs.launchpad.net/liberasurecode/+bug/1886088 for more
information, including a script you can run on already-written
fragments to determine whether you are affected.
If you are affected:
- Upgrade liberasurecode on all systems, restarting processes as needed.
Upgraded writers will continue writing CRCs that not-yet-upgraded
readers can use.
- After liberasurecode is upgraded everywhere, remove the environment
variable. zlib CRCs will be used for new writes, and data written with
either CRC will still be readable.
