### Apache Iceberg version
main (development)
### Query engine
None
### Please describe the bug 🐞
It seems stats diff is computed only from the current snapshot, which may
not track deleted files. For example the following test case would fail:
```java
@Test
public void test() throws Exception {
Table testTable =
TestTables.create(tempDir("my_test"), "my_test", SCHEMA, SPEC, 2,
fileFormatProperty);
DataFile dataFile1 =
DataFiles.builder(SPEC)
.withPath("/df1.parquet")
.withPartitionPath("c2=a/c3=a")
.withFileSizeInBytes(10)
.withRecordCount(1)
.build();
DataFile dataFile2 =
DataFiles.builder(SPEC)
.withPath("/df2.parquet")
.withPartitionPath("c2=b/c3=b")
.withFileSizeInBytes(10)
.withRecordCount(1)
.build();
testTable.newAppend().appendFile(dataFile1).appendFile(dataFile2).commit();
testTable
.updatePartitionStatistics()
.setPartitionStatistics(PartitionStatsHandler.computeAndWriteStatsFile(testTable))
.commit();
testTable.newDelete().deleteFile(dataFile1).commit();
testTable.newDelete().deleteFile(dataFile2).commit();
PartitionStatisticsFile statsFile =
PartitionStatsHandler.computeAndWriteStatsFile(testTable);
assertThat(
PartitionStatsHandler.readPartitionStatsFile(
PartitionStatsHandler.schema(Partitioning.partitionType(testTable)),
Files.localInput(statsFile.path())))
.allMatch(s -> s.dataRecordCount() == 0);
}
```
