From the following:
http://dev.mysql.com/doc/refman/5.6/en/timestamp-initialization.html
it looks like the semantics of "timestamp" may have changed in 5.6.
Maybe we need to declare that field differently.
(We use "timestamp" in workunit, result, and several forum-related tables.)

I don't have a 5.6 server set up right now; I'll do that soon.
In the meantime, can anyone poke around and see what's going on?

I'm running 5.6.12 and I'm missing the on update CURRENT_TIMESTAMP

Are there other timestamps that should have that?

That's odd;
workunit.mod_time is of type "timestamp",
which means that it's supposed to get automatically set (by MySQL)
to the current date/time whenever the row is modified.

When you do "explain workunit" in mysql, what do you see for mod_time?
On my server (5.5.23) I see

   Field: mod_time
    Type: timestamp
    Null: NO
     Key:
Default: CURRENT_TIMESTAMP
   Extra: on update CURRENT_TIMESTAMP

What version of MySQL are you using?

Is the db_purge working in the latest and greatest from Git?

I'm using it like this
db_purge -min_age_days 14 --max_wu_per_file 10000 --gzip --daily_dir --one_pass 
-d 3

Looking at the code in db_purge.cpp the do_pass routine
     bool did_something = false;
     DB_WORKUNIT wu;
     char buf[256];

     if (min_age_days) {
         min_age_seconds = (int) min_age_days*86400;
         if (id_modulus) {
             sprintf(buf,
                 "where file_delete_state=%d and mod_time<current_timestamp() - 
interval %d second and id %% %d = %d limit %d",
                 FILE_DELETE_DONE, min_age_seconds, id_modulus, id_remainder, 
DB_QUERY_LIMIT
             );
         } else {
             sprintf(buf,
                 "where file_delete_state=%d and mod_time<current_timestamp() - 
interval %d second limit %d",
                 FILE_DELETE_DONE, min_age_seconds, DB_QUERY_LIMIT
             );
         }
     } else {
         if (id_modulus) {
             sprintf(buf,
                 "where file_delete_state=%d and id %% %d = %d limit %d",
                 FILE_DELETE_DONE, id_modulus, id_remainder, DB_QUERY_LIMIT
             );
         } else {
             sprintf(buf,
                 "where file_delete_state=%d limit %d",
                 FILE_DELETE_DONE, DB_QUERY_LIMIT
             );
         }
     }

     int n=0;
     while (1) {
         retval = wu.enumerate(buf);
         if (retval) {


The code should create the where clause
where file_delete_state=%d and mod_time<current_timestamp() - interval %d 
second limit %d

But in my database for work units mod_time is null for everything. Looking at 
file_deleter.cpp it seems to only set file_delete_state.

Anyone seen anything like this before?

Kevin
