Cleanup_database can delete all statistics entries more than X days
old. If one is using pseudonymization to create pseudonymized_transactions
data, then one may wish to use that cleanup_database function to delete
statistics entries that have been duplicated in pseudonymized_transactions.
However, not all types of transactions in statistics are duplicated in
pseudonymized transactions.
Pseudonymized_transactions currently only includes checkouts, returns,
and renewals.
This patch adds two additional parameters to cleanup_database.pl:
1. --statistics-type
Defines the types of statistics to purge. Will purge all types if
parameter is omitted. Repeatable.
2. --statistics-type-pseudo
Grabs values from @Koha::Statistic::pseudonymization_types. At the
time of writing this patch, they are:
renew, issue, return and onsite_checkout
To test:
1. prove t/db_dependent/Koha/Statistic.t
2. Before applying this patch:
3. Create some statistics entry by checking out, renewing and checking in
items.
4. perl misc/cronjobs/cleanup_database.pl --statistics 1 --verbose
Observe:
Purging statistics older than 1 days
n statistics would have been removed
Where n is the amount of statistics rows matching your test environment
5. Apply patch
6. Repeat step 4, observe same result
7. perl misc/cronjobs/cleanup_database.pl --statistics 1 --statistics-type-pseudo --verbose
Observe:
Purging statistics older than 1 days with types "onsite_checkout,renew,return,issue".
n statistics would have been removed
Where n is the amount of statistics rows matching your test environment
(order of listed types does not matter)
8. perl misc/cronjobs/cleanup_database.pl --statistics 1 --statistics-type test1 --statistics-type test2 --verbose
Observe:
Purging statistics older than 1 days with types "test1,test2".
n statistics would have been removed
Where n is the amount of statistics rows matching your test environment
(order of listed types does not matter)
9. perl misc/cronjobs/cleanup_database.pl --statistics 1 --statistics-type-pseudo --statistics-type test1 --verbose
Observe:
Purging statistics older than 1 days with types "test1,onsite_checkout,renew,return,issue".
n statistics would have been removed
Where n is the amount of statistics rows matching your test environment
(order of listed types does not matter)
10. Try previous cleanup_database.pl commands with --confirm flag and make sure correct rows are purged
