[Tarantool-patches] [PATCH 0/3] Safe allocation on truncation and deletion

[Ilya Kosarev]

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 denial of extra
memory reservation and unconstrained allocation of service tuples
in BOX_TRUNCATE_ID space.

Branch: https://github.com/tarantool/tarantool/tree/i.kosarev/gh-3807-safe-alloc-on-truncation
Issue: https://github.com/tarantool/tarantool/issues/3807

Ilya Kosarev (3):
  b-tree: return NULL on matras_alloc fail
  memtx: don't reserve extra memory if not needed
  tuple: use calloc for service truncation tuples
