------------------------------------
Summary: MemoryPool's Release_All() should free
Key: LUCY-263
URL: https://issues.apache.org/jira/browse/LUCY-263
Project: Lucy
Issue Type: Bug
Components: Index, Util
Affects Versions: 0.3.3, 0.3.2, 0.3.1, 0.3.0 (incubating), 0.2.2
(incubating), 0.2.1 (incubating), 0.2.0 (incubating), 0.1.0 (incubating)
Reporter: Marvin Humphrey
Assignee: Marvin Humphrey
Fix For: 0.3.4, 0.4.0
The MemoryPool method Release_All() was originally conceived to allow
reuse of arena memory after being invoked, but that is not how it is
being used -- existing call sites in PostingListWriter, SortWriter and
SortFieldWriter expect the memory to be freed, resulting in memory
leaks. This phenomenon is probably behind out-of-memory issues which
may occur on lengthy indexing sessions. To fix these problems, the most
straightforward approach is to change the behavior of Release_All() to
free memory.
