Description Andrew Fuerste-Henry 2020-09-24 15:07:22 UTC
To recreate:
1 - Set ReservesControl to item home library
2 - confirm your circ rules allow holds at both the All Libraries and library-specific levels
3 - confirm Default checkout, hold and return policy is totally unset at both the All Libraries and library-specific levels
4 - place a hold on an item at Branch A for pickup at Branch A
5 - check item in, confirm hold triggers
6 - cancel hold
7 - go to Default checkout, hold and return policy for Branch A
8 - enter 1 for Total current checkouts allowed, save that with no other values entered
9 - re-place hold, confirm no error when placing hold
10 - check item in, hold does not trigger
11 - set Hold policy and Hold pickup library match at to Any Library at All Libraries level
12 - confirm hold still doesn't capture
set Hold policy and Hold pickup library match at to Any Library for Branch A
13 - confirm hold now captures

If these rules aren't set at the branch level we should be falling back to All Libraries. If they're not set anywhere, we should be assuming holds are allowed is the circ rules allow them.

Starting from default testing docker data, this is what my db shows at step 7:
MySQL [koha_kohadev]> select * from circulation_rules;
+----+------------+--------------+----------+-------------------+------------+
| id | branchcode | categorycode | itemtype | rule_name         | rule_value |
+----+------------+--------------+----------+-------------------+------------+
|  1 | NULL       | NULL         | NULL     | maxissueqty       | 5          |
|  2 | NULL       | NULL         | NULL     | maxonsiteissueqty | 5          |
+----+------------+--------------+----------+-------------------+------------+

And this is what it shows at step 8:
MySQL [koha_kohadev]> select * from circulation_rules;
+----+------------+--------------+----------+--------------------------+------------+
| id | branchcode | categorycode | itemtype | rule_name                | rule_value |
+----+------------+--------------+----------+--------------------------+------------+
|  1 | NULL       | NULL         | NULL     | maxissueqty              | 5          |
|  2 | NULL       | NULL         | NULL     | maxonsiteissueqty        | 5          |
|  8 | CPL        | NULL         | NULL     | patron_maxissueqty       | 1          |
|  9 | CPL        | NULL         | NULL     | returnbranch             |            |
| 10 | CPL        | NULL         | NULL     | hold_fulfillment_policy  |            |
| 11 | CPL        | NULL         | NULL     | patron_maxonsiteissueqty |            |
| 12 | CPL        | NULL         | NULL     | max_holds                |            |
+----+------------+--------------+----------+--------------------------+------------+

Bug 26529: Define some rules as not able to be blank

This patch uses the existing hash that controls the scope of rules and adds a
new parameter 'can_be_blank'

To test:
1 - Goto to Admin -> Circulation and fines rules and select a library
2 - Under "Default checkout, hold, and return policy" set:
    Total current checkouts allowed: 1
    Hold policy: Not set
    Hold pickup library match: Not set
    Return policay: Not set
3 - Save the rule
4 - Check the DB
    SELECT * FROM circulation_rules WHERE branchcode = 'BRANCHCODE'
    using the branchcode for the library you chode
5 - Note holdallowed, returnbranch, and hold_fulfillment_policy rules exist with blank value
6 - Apply patch and restart all the things
7 - Reload the page and save the rules as before
8 - Check the DB and note the rules no longer exist
9 - pr0ve -v t/db_dependent/Koha/CirculationRules.t

Comment 7 Katrin Fischer 2020-09-26 20:39:54 UTC
This one is confusing to me...

1) Andrew said he could not reproduce the problem neither in master nor in 20.05.
2) The test plan of the patch does only show the difference in the data, but doesn't explain why this change is important and how it related to the initial hold issue.
3) Same for the test - it only verifies that no rules with "" are entered.
4) There is no database update to remove problmatic(?) empty rules.

Can we have some more information here?

Bug 26529: Define some rules as not able to be blank

Currently, the 'Default checkout, hold, and return policy' have a conditional to blank
'holdallowed' when not set, but other rules don't get the same treatment

This patch uses the existing hash that controls the scope of rules and adds a
new parameter 'can_be_blank' Default is assumed to be true, can_be_blank, but if set to '0' then
blank rule values will not be save to the database

To test:
 0 - Set CircControl to 'the library the item is from'
 1 - Goto to Admin -> Circulation and fines rules and select a library
 2 - Under "Default checkout, hold, and return policy" set:
    Total current checkouts allowed: 1
    Hold policy: Not set
    Hold pickup library match: Not set
    Return policy: Not set
 3 - Save the rule
 4 - Check the DB
    SELECT * FROM circulation_rules WHERE branchcode = 'BRANCHCODE'
    using the branchcode for the library you chode
 5 - Note returnbranch, and hold_fulfillment_policy rules exist with blank value
 6 - Set 'All libraries'->'Default checkout, hold and return policy'->'Item floats'
 7 - Checkin an item from the library with blank rules at another library
 8 - It returns home rather than floating
 9 - Apply patch and restart all the things
10 - Reload the page and save the rules as before
11 - Check the DB and note the rules no longer exist
12 - Check in the item, it floats!
13 - prove -v t/db_dependent/Koha/CirculationRules.t

Bug 26529: Unit tests

This tests tries to set some rules to blank, and then fetch the effective rule - nothing should be
returned as these values are 'Not set'

To test:
1 - Apply just this patch
2 - Tests fail
3 - Apply second patch
4 - Tests pass

If testing only 'holdallowed' the problem is not apparent as we catch that case in the script

Updated test plan with a test to illustrate the problem

> 3) Same for the test - it only verifies that no rules with "" are entered.

It also verifies that those rules aren't returned - run the tests on their own and they fail on master

> 4) There is no database update to remove problmatic(?) empty rules.

Comment 15 Martin Renvoize 2020-10-05 16:06:16 UTC
This all works well and I'm surprised we didn't already handle such cases.

Unit tests pass and we're dealing with the obvious cases where rules should not be blank.

I suspect there may be a few other cases crop up in the future where we've been allowing errant blank rules in, but we can handle them as we find them.

Passing QA
Comment 16 Jonathan Druart 2020-10-08 08:13:23 UTC
Should not we then remove those 2 lines?

466     $holdallowed =~ s/\s//g;
