Subject: [PATCH 500/511] features/shard: Convert shard block indices to uint64
|
|
|
17b94a |
|
|
|
17b94a |
This patch fixes a crash in FOPs that operate on really large sharded
|
|
|
17b94a |
files where number of participant shards could sometimes exceed
|
|
|
17b94a |
signed int32 max.
|
|
|
17b94a |
|
|
|
17b94a |
The patch also adds GF_ASSERTs to ensure that number of participating
|
|
|
17b94a |
shards is always greater than 0 for files that do have more than one
|
|
|
17b94a |
shard.
