## first step execute SQL to export list of duplicate Build_ID
cur.execute('SELECT builds.Build_ID, Job_Name, Build_Number, Start_Time \ FROM Jenkins_Builds builds INNER JOIN ( \ SELECT Build_ID FROM Jenkins_Builds \ WHERE Build_ID IN (SELECT Build_ID FROM CII_Builds) \ GROUP BY Build_ID HAVING Count(Build_ID) > 1 \ ) duplicate ON builds.Build_ID = duplicate.Build_ID \ ORDER BY builds.Job_Name, builds.Build_Number ')  


for user in cur.fetchall():
    start_list.append(user)


for x in start_list:
    if  Job_name_dict.has_key(x[1]):
        Job_name_dict[x[1]].append(x)
        Job_name_dict[x[1]]=sorted(Job_name_dict[x[1]],key=lambda x : x[2])
    else:

        Job_name_dict[x[1]].append(x)
    if entry_build_id.has_key(x[1]):
        continue

    else:
        Job_Build_Number_dict[x[1]] = list()
        Job_Build_Number_dict[x[1]].append(x[2])


##second 2 pick one duplicated Build_ID, (with job_name & build_number in hand),
for a in Job_name_dict:
    i=1
    for x in Job_name_dict[a]:
        lenx=len(Job_name_dict[a])
        if i<lenx:
            if  new_Build_dict.has_key(Job_name_dict[a][i][1]):
                new_Build_dict[Job_name_dict[a][i][1]].append(Job_name_dict[a][i][2])
            else:
                new_Build_dict[Job_name_dict[a][i][1]] = list()
                new_Build_dict[Job_name_dict[a][i][1]].append(Job_name_dict[a][i][2])

            try:
                str_duplicate="P_DUPUUID '%s', @Do_Delete=1" % Job_name_dict[a][i][0]
            except:
                print 'none'
            cur.execute(str_duplicate)
            i=i+1
        else:
            break


##second 3 get the new Build_ID
for x in new_Build_dict:
    for y in new_Build_dict[x]:
        str_build="select Build_ID from Jenkins_Builds where Job_Name='%s' and Build_Number=%d" % (x,y)
        cur.execute(str_build)
        for user in cur.fetchall():
            if new_Build_Id_dict.has_key(x):
                new_Build_Id_dict[x].append(user)
            else:
                new_Build_Id_dict[x] = list()
                new_Build_Id_dict[x].append(user)
            new_Build_list.append(user)

##step4 get the runtime Platform ,Language and Start_Time 
for x in new_Build_list:
    str_new_Build="SELECT jenkins.Display_Name, Build_Type, Platform, Language, jenkins.Start_Time FROM CII_Builds cii \ INNER JOIN Jenkins_Builds jenkins ON jenkins.Build_ID = cii.Build_ID \ WHERE cii.Build_ID = '%s' \ " % x
    cur.execute(str_new_Build)
    for user in cur.fetchall():
            runtime_list.append(user)

##step 5 find sub job by platform and start_time
for x in runtime_list:
    mytime = str(x[4]).split(".")[0]
    sub_job_build="SELECT jenkins.Start_Time, jenkins.Build_Number, jenkins.Duration, jenkins.Result ,* FROM Jenkins_Builds jenkins\ WHERE Job_Name = '%s' \ AND Start_Time >= '%s' \ ORDER BY jenkins.Build_Number\ "%(x[0],mytime)
    cur.execute(sub_job_build)
    for user in cur.fetchall():
        sub_job_list.append(user)

## step 6 create relation 
for x in entry_build_id:
    for m in entry_build_id[x]:
        cur.execute('DELETE FROM CII_Build_Detail WHERE Entry_Build_ID = %s',m)
        #print 'ok'
        for y in new_Build_Id_dict[x]:
            cur.execute("INSERT INTO CII_Build_Detail SELECT j.Build_ID, %s, 'linux', 'en', j.Duration, j.Result \ FROM Jenkins_Builds j WHERE j.Build_ID = %s ",(m,y))
            #print 'right'

cur.close()
