Description joachim.ganseman 2016-09-29 21:44:49 UTC
Created attachment 55947 [details]
Example: after trying to merge PERSO_NAME and TOPIC_TERM "Rossini", the PERSO_NAME record is now authtypecoded as "default" and cannot be edited anymore

Editing authorities whose authtypecode is not set to a common value is not possible in Koha 16.05 .

This occurs e.g. after trying to (accidentally) merge a PERSO_NAME and TOPIC_TERM authority into one. The resulting authority will have its authtypecode set to "default".

Upon trying to correct such an authority, it turns out to be impossible to edit the said authority. An error very similar to 'Can't call method "authtypecode" on an undefined value' appears instead of the editor.

This occurs even when there are no authority frameworks defined (i.e. all in the default frameworks), in Koha 16.05 on Debian.
Comment 1 Jonathan Druart 2016-10-05 07:51:29 UTC
Could you give us the exact error with the file and line number where it crashes?
Comment 2 Marcel de Rooy 2017-02-23 09:00:10 UTC

Bug 17380: Add some checks around Authorities::Types->find

Resolves:
Use of uninitialized value $biblio_fields in scalar chop at authorities/detail.pl line 212.
Can't call method "authtypetext" on an undefined value at authorities/detail.pl line 216.
Can't call method "authtypecode" on an undefined value at authorities/detail.pl line 180.

NOTE: Some of these problems have actually been resolved now by bugs 18801
and 18811, but it is still better imo to have these checks.

Test plan:
[1] Verify unchanged behavior. Search for some authorities on authorities.pl
    and click on the details of a record.
[2] Open an authorities detail page and change the authid in the URL to a
    not existing number. Instead of an internal server error, you should see
    a message like "The authority record you requested does not exist".

Bug 17380: Do not use GuessAuthTypeCode in MetadataRecord::Authority

If we got an authtypecode from the database and this value is not NULL
since the table column does not allow it, there is no need to call
GuessAuthTypeCode for empty string (read: Default framework) in the
sub get_from_authid.

Furthermore, we remove three Koha::MetadataRecord::Authority->new calls.
They are useless, since we do not pass a record. It just generates:
  No record passed at authorities/merge.pl line 96.
  Can't bless non-reference value at Koha/MetadataRecord/Authority.pm line 66.
Instead we throw an ObjectNotFound exception.

Test plan:
[1] Run t/db_dependent/Koha_Authority.t
[2] Interface will be tested in the following patches.

Bug 17380: Graceful resolution of missing reporting tag in merge

Altough this patch deals with a mostly hypothetical case and this report
makes it practically impossible anymore to merge with records in the
Default framework (having no reporting tag), we can make the code of
sub merge still a bit more robust here.

If you would merge biblio records from one authtype to another and the new
framework would not have a reporting tag, before this patch the result would
be data loss. Merge would handle this request as a delete. This patch makes
merge handle it differently: instead of clearing the biblio records, it
keeps $a and $9 in order to make a future corrective merge possible.

Note: The additional condition on line 1468 for $tags_using_authtype
makes sure that we do not select all fields when the authtype should
unexpectedly be empty string (Default). This prevents crashing on
a "Control fields do not have subfields" error.

Test plan:
[1] Run t/db_dependent/Authorities/Merge.t

Bug 17380: Do not allow Default template in merge form

This patch makes the following changes:
[1] Removes Default from the template list. We should not merge with the
    Default framework, since it does not have a reporting tag.
[2] Rearranges the error section in the template. It is confusing to have
    two error sections in this template. The error CANNOT_MOVE is not used.
    The error FRAMEWORK_NOT_SELECTED is replaced by WRONG_FRAMEWORK.
[3] Do not allow to merge a record with itself.
[4] Check if the merge reference record still contains any MARC tags.
[5] Additional polishing: Simplify passing frameworks to template. Remove
    an unused Koha::Authority::Types->search. Remove obsolete POD header
    for functions from the script.

Test plan:
[1] Select two authorities to merge. Verify that you cannot select Default
    anymore as framework for the reference record.
[2] Reproduce error WRONG_COUNT by adding another authid=999 in the URL
    after you selected two authority records for merging.
[3] Remove the third authid from the URL and change the first or second
    authid into an unexisting record id. You should generate an Internal
    Server Error. The log should show the exception message.
[4] Merge two authorities. Deselect all MARC tags. Should trigger the
    error EMPTY_MARC in the template.
[5] Select the same authority record twice for merging. Should trigger the
    error DESTRUCTIVE_MERGE in the template.

Bug 17380: Add some checks around Authorities::Types->find

Resolves:
Use of uninitialized value $biblio_fields in scalar chop at authorities/detail.pl line 212.
Can't call method "authtypetext" on an undefined value at authorities/detail.pl line 216.
Can't call method "authtypecode" on an undefined value at authorities/detail.pl line 180.

NOTE: Some of these problems have actually been resolved now by bugs 18801
and 18811, but it is still better imo to have these checks.

Test plan:
[1] Verify unchanged behavior. Search for some authorities on authorities.pl
    and click on the details of a record.
[2] Open an authorities detail page and change the authid in the URL to a
    not existing number. Instead of an internal server error, you should see
    a message like "The authority record you requested does not exist".

Bug 17380: Do not use GuessAuthTypeCode in MetadataRecord::Authority

If we got an authtypecode from the database and this value is not NULL
since the table column does not allow it, there is no need to call
GuessAuthTypeCode for empty string (read: Default framework) in the
sub get_from_authid.

Furthermore, we remove three Koha::MetadataRecord::Authority->new calls.
They are useless, since we do not pass a record. It just generates:
  No record passed at authorities/merge.pl line 96.
  Can't bless non-reference value at Koha/MetadataRecord/Authority.pm line 66.
Instead we throw an ObjectNotFound exception.

Test plan:
[1] Run t/db_dependent/Koha_Authority.t
[2] Interface will be tested in the following patches.

Bug 17380: Graceful resolution of missing reporting tag in merge

Altough this patch deals with a mostly hypothetical case and this report
makes it practically impossible anymore to merge with records in the
Default framework (having no reporting tag), we can make the code of
sub merge still a bit more robust here.

If you would merge biblio records from one authtype to another and the new
framework would not have a reporting tag, before this patch the result would
be data loss. Merge would handle this request as a delete. This patch makes
merge handle it differently: instead of clearing the biblio records, it
keeps $a and $9 in order to make a future corrective merge possible.

Note: The additional condition on line 1468 for $tags_using_authtype
makes sure that we do not select all fields when the authtype should
unexpectedly be empty string (Default). This prevents crashing on
a "Control fields do not have subfields" error.

Test plan:
[1] Run t/db_dependent/Authorities/Merge.t

Bug 17380: Do not allow Default template in merge form

This patch makes the following changes:
[1] Removes Default from the template list. We should not merge with the
    Default framework, since it does not have a reporting tag.
[2] Rearranges the error section in the template. It is confusing to have
    two error sections in this template. The error CANNOT_MOVE is not used.
    The error FRAMEWORK_NOT_SELECTED is replaced by WRONG_FRAMEWORK.
[3] Do not allow to merge a record with itself.
[4] Check if the merge reference record still contains any MARC tags.
[5] Additional polishing: Simplify passing frameworks to template. Remove
    an unused Koha::Authority::Types->search. Remove obsolete POD header
    for functions from the script.

Test plan:
[1] Select two authorities to merge. Verify that you cannot select Default
    anymore as framework for the reference record.
[2] Reproduce error WRONG_COUNT by adding another authid=999 in the URL
    after you selected two authority records for merging.
[3] Remove the third authid from the URL and change the first or second
    authid into an unexisting record id. You should generate an Internal
    Server Error. The log should show the exception message.
[4] Merge two authorities. Deselect all MARC tags. Should trigger the
    error EMPTY_MARC in the template.

Pushed to 17.05.x, will be in 17.05.06.

Needed to revert "Bug 17380: (QA followup) Fix parameter in tests" because C4::Biblio::GetMarcBiblio has not changed in 17.05.x

Doesn't apply cleanly on 16.11.x, please rebase if you want this to be included.

See comment on the dependency 18811.
Recommend to close it now.
Comment 39 Katrin Fischer 2017-10-30 13:18:36 UTC
Looking at Marcel's comments, this won't get pushed to 16.11.x. Closing.
