Error when updating Drupal 6 to Drupal 7

Can someone reproduce this?

I have what appears to be the same issue.

The following updates are pending:

masquerade module : 
  7000 -   Update masquerade block delta. 
  7001 -   Update masquerade block caching. 

Do you wish to run all pending updates? (y/n): y
7000SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'marinelli-masquerade-masquerade' for key 'tmd'                          [error]

Finished performing updates.           

In case it helps, here are the relevant database table rows:

+-----+------------+------------+---------------+--------+--------+---------------+--------+------------+-------+-------+-------+

Note that the blocks with IDs 375 and 679 have the same theme ("marinelli") and module ("masquerade") in the table results.

Quick Fix: I was able to get the update to run by removing the almost-duplicate row (679 in this example).

The other thing that may be unique about my situation I should note is that this happened during a Drupal upgrade (using drush site-upgrade from 6 to 7), where Marinelli theme was downloaded and upgraded (and drush had incorrectly downloaded it to the modules directory so I had to move it and enable it manually).

After masquerade_update_7000() ran without errors, my table looked as it should:

mysql> select * from drupal_block where module = 'masquerade';

Hope that helps anyone else who might have this issue.

Upgrading from Masquerade 6.x-1.9 to 7.x-1.0-rc7 received the error

a. Update #7000 Failed: PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'garland-masquerade-masquerade' for key 'tmd': UPDATE {block} SET delta=:db_update_placeholder_0 WHERE (module = :db_condition_placeholder_0) AND (delta = :db_condition_placeholder_1) ; Array ( [:db_update_placeholder_0] => masquerade [:db_condition_placeholder_0] => masquerade [:db_condition_placeholder_1] => 0 ) in masquerade_update_7000() (line 171 of sites\all\modules\masquerade\masquerade.install).

Contents of blocks table (minus a couple of columns) as follows

| bid | module     | delta      | theme   | status | weight | region |

| 47  | masquerade | 0          | irecord | 1      | -9     | footer |

| 67  | masquerade | masquerade | garland | 0      | 0      | -1     |

Deleted block with bid=67, ran update.php again and all seems well.

Thanks kruser. Worked a treat

Well this is a weird one. This module's update code (7000 and 7001) both looks fine and should not cause this problem. I too experienced this doing a D6 -> D7 upgrade. I was using drush for the upgrade. My D6 DB has the following (similar column values omitted for brevity):

+-----+-------+-----------+--------+--------+--------+-------+
| bid | delta | theme     | status | weight | region | cache |
+-----+-------+-----------+--------+--------+--------+-------+
| 223 | 0     | co_custom |      1 |    -66 | right  |    -1 |
| 226 | 0     | blueprint |      0 |      0 |        |    -1 |
| 293 | 0     | garland   |      0 |      0 |        |    -1 |
+-----+-------+-----------+--------+--------+--------+-------+

But the D7 DB has:

+-----+------------+-----------+--------+--------+----------------+-------+
| bid | delta      | theme     | status | weight | region         | cache |
+-----+------------+-----------+--------+--------+----------------+-------+
| 223 | masquerade | co_custom |      1 |    -66 | sidebar_second |    -1 |
| 226 | masquerade | blueprint |      0 |      0 |                |    -1 |
| 293 | 0          | garland   |      0 |      0 |                |    -1 |
| 508 | masquerade | garland   |      0 |      0 | -1             |    -1 |
+-----+------------+-----------+--------+--------+----------------+-------+

I have no idea where bid '508' came from and bid '293' should have delta 'masquerade'. This looks to be caused by another module?

Can confirm this issue as well from a Drupal 6 -> 7 site upgrade.

Haven't got time to step through exactly and see why there are 'duplicate' blocks being inserted into the database *with* the masquerade delta, thus causing masquerade_update_7000 to fail.

Confirmed that the quick fix is to delete the duplicate entries in the {block} table, maybe one day if I have more time can try and see at what point in the site upgrade process this issue occurs and can work a fix :)

#2 works for me ...Thanks
