Description Julian Maurice 2013-05-03 15:19:59 UTC
Update number 3.09.00.025 can remove all reserves from reserves table when there is no entries in old_reserves.
This is due to @ai which is set to NULL in
  SET @ai = ( SELECT MAX( reserve_id ) FROM tmp_reserves )
and reserve_id > NULL returns no results in
  INSERT INTO reserves SELECT * FROM tmp_reserves WHERE reserve_id > @ai

This can be fixed easily by using COALESCE
  INSERT INTO reserves SELECT * FROM tmp_reserves WHERE reserve_id > COALESCE(@ai, 0)

Comment 4 Katrin Fischer 2013-05-04 08:44:12 UTC
Can you please write a test plan for this?
Comment 5 Julian Maurice 2013-05-05 08:48:24 UTC
1/ Do a fresh 3.8 install
2/ Do some reserves
3/ Check your old_reserves table is empty
4/ Update your sources to 3.10
5/ Run updatedatabase.pl
6/ Your reserves table is now empty!

Now repeat steps 1 to 4, then apply the patch and run updatedatabase.pl
Your reserves table should still contains the reserves made at step 2
Comment 6 Katrin Fischer 2013-05-05 20:06:51 UTC
Thank you, Julian!
Comment 7 Katrin Fischer 2013-05-05 21:20:37 UTC
Hi Julian,

thx for the test plan. It works as described, but I found something that is weird here - we are losing the suspended holds in the update process.
The reserves seem ok, but the suspend_until is empty after the update.
Comment 8 Katrin Fischer 2013-05-05 21:39:39 UTC
Ok, I guess I found it: suspend_until is missing from the update?

Could you take a look at that and add a follow up?

It can remove all reserves from reserves table when there is no entries
in old_reserves.
This is due to @ai which is set to NULL in
  SET @ai = ( SELECT MAX( reserve_id ) FROM tmp_reserves )
and reserve_id > NULL returns no results in
  INSERT INTO reserves SELECT * FROM tmp_reserves WHERE reserve_id > @ai

SQL only changes fixing an important database update.

IMPORTANT: Patches must be backported to all versions containing
the database update 3.09.00.025.

I used the test plan provided by Julian with some additions:
1/ Do a fresh 3.8 install
2/ Do some reserves
3/ Check your old_reserves table is empty
4/ Update your sources to 3.10
5/ Run updatedatabase.pl
6/ Your reserves table is now empty!

I made sure I had item level and title level holds, also
suspended holds.

I repeated the test with entries in my old_reserves table
(cancelled and filled holds) to make sure this is also still
working correctly.

Before the patch we lost all suspended holds and when the
old_reserves table was empty also all holds in general.
After the patch the reserve_id is added but the other data
in both tables is not altered.

NOTE: Adding the reserve_id first to old_reserves and then
to reserves we are missing one id in between.
old_reserves: 1,2,3
reserves: 5,6
Comment 17 Katrin Fischer 2013-05-07 06:50:06 UTC
Treating the second patch as a QA follow up.

Comment 20 Julian Maurice 2013-06-13 08:55:23 UTC
Ok in master, 3.12.x and 3.10.x
