---------------------------------------
Summary: Incorrect assertion for cache size
Key: IGNITE-5950
URL: https://issues.apache.org/jira/browse/IGNITE-5950
Project: Ignite
Issue Type: Bug
Components: persistence
Affects Versions: 2.1
Reporter: Sergey Chugunov
Assignee: Sergey Chugunov
Priority: Critical
Fix For: 2.2
*PagePartitionCountersIO::readCacheSizes* incorrectly asserts cache size:
{noformat}
public boolean readCacheSizes(long pageAddr, Map<Integer, Long> res) {
int cnt = getCount(pageAddr);
assert cnt >= 0 && cnt <= Short.MAX_VALUE : cnt;
if (cnt == 0)
return true;
int off = ITEMS_OFF;
for (int i = 0; i < cnt; i++) {
int cacheId = PageUtils.getInt(pageAddr, off);
off += 4;
assert cacheId != 0;
long cacheSize = PageUtils.getLong(pageAddr, off);
off += 8;
assert cacheSize > 0 : cacheSize; //WRONG assertion! cache of zero
size if totally legal
Long old = res.put(cacheId, cacheSize);
assert old == null;
}
return getLastFlag(pageAddr);
}
{noformat}
Correct assertion is {{cacheSize >= 0}}.
