mysqldumpslow does not aggregate times.

Best regards

Martin Kirchner

How to repeat:
I activated the slow query log and produced some slow queries. The slow query log contains now entries like 

# Time: 080129 11:51:12
# User@Host: root[root] @ localhost []
# Query_time: 0.001565  Lock_time: 0.000051 Rows_sent: 1  Rows_examined: 1839
SET timestamp=1201603872;
SELECT COUNT(*) FROM city_huge, Country WHERE city_huge.CountryCode=Country.Code AND Country.Continent='Asia' AND Country.Population < 1000000;

If I now run mysqldumpslow the aggregated times are always 0.00:

Count: 8  Time=0.00s (0s)  Lock=0.00s (0s)  Rows=0.0 (0), root[root]@localhost
  # Query_time: N.N  Lock_time: N.N Rows_sent: N  Rows_examined: N
  SET timestamp=N;
  SELECT COUNT(*) FROM city_huge, Country WHERE city_huge.CountryCode=Country.Code AND Country.Continent='S' AND Country.Population < N

Here is a working fix for this problem:

Line 86 has to be

s/^# Query_time: (\d+\.?\d*)\s+Lock_time: (\d+\.?\d*)\s+Rows_sent: (\d+\.?\d*).*\n//;

instead of

s/^# Query_time: (\d+)  Lock_time: (\d+)  Rows_sent: (\d+).*\n//;

      Bug#34129: mysqldumpslow does not aggregate times
      Query times were changed to contain subsecond information after a decimal.
      Change the capturing regex to account for decimal also.
