| -** This file contains code to support the concept of "benign"
|
| -** malloc failures (when the xMalloc() or xRealloc() method of the
|
| -** sqlite3_mem_methods structure fails to allocate a block of memory
|
| -** and returns 0).
|
| -**
|
| -** Most malloc failures are non-benign. After they occur, SQLite
|
| -** abandons the current operation and returns an error code (usually
|
| -** SQLITE_NOMEM) to the user. However, sometimes a fault is not necessarily
|
| -** fatal. For example, if a malloc fails while resizing a hash table, this
|
| -** is completely recoverable simply by not carrying out the resize. The
|
| -** hash table will continue to function normally. So a malloc failure
|
| -** during a hash table resize is a benign fault.
