2  v10r18  :       BUG FIXED: crash (ToF, probably also CALO and ORB) when reprocessing full file (probably any reprocessing) without extended tracks  v10r18  :       BUG FIXED: crash (ToF, probably also CALO and ORB) when reprocessing full file (probably any reprocessing) without extended tracks
3                  New methods for tracks retrieving added in CaloLevel2.h, ToFLevel2.h and OrbitalInfo.h                  New methods for tracks retrieving added in CaloLevel2.h, ToFLevel2.h and OrbitalInfo.h
4    v10r19  :       testing purpose (ExtTrack processing only)
5    v10r20  :       BUG FIXED: crash due to new default in MySQL >=5.5.5,
6                    The query that is failing is something like:
7                    select ID_ROOT_L0, FROM_TIME, TO_TIME, EV_ROOT from GL_CALO_CALIB where SECTION=0 and VALIDATION=1 ORDER BY ABS(1322051607-FROM_TIME) asc limit 1
8                    this issue and it seems that is related to the "NO_UNSIGNED_SUBTRACTION" mode of MySQL.
9                    "As of MySQL 5.5.5, overflow during numeric expression evaluation results in
10                    an error. For example, the largest signed BIGINT value is
11                    9223372036854775807, so the following expression produces an error."
12                    You can find other infos about this here
13                    http://dev.mysql.com/doc/refman/5.5/en/server-sql-mode.html
14                    essentialy now, by default, subtraction between integer operands produces an
15                    UNSIGNED result if any operand isUNSIGNED. This is something that I think is
16                    weird and in the code there is not such an assumption of course, I expect
17                    that the subtraction between two unsigned integer COULD result in a negative number...
