space:truncate() and space:delete() could fail on memory allocations
when reaching memtx_memory limit. As far as it is quite an ill
behaviour, it is fixed in this patchset through memtx quota enlargement.
Also possible bps_tree_create_leaf NULL dereference issue is fixed.
Branch: https://github.com/tarantool/tarantool/tree/i.kosarev/gh-3807-safe-alloc-on-truncation
Issue: https://github.com/tarantool/tarantool/issues/3807
Changes in v2:
Approach changed completely: now we are not trying to allocate
service tuples in some safe way, but increasing memtx quota so
that space:truncate() and space:delete() won't fail on allocation.
Ilya Kosarev (2):
b-tree: return NULL on matras_alloc fail
memtx: increase the memory quota if needed to truncate or delete
