[EP-tech] use of uninitialized value in string eq during eprint->commit
Hi David,
Thank you! That is brilliant use of grep. Using this method, I was able to pinpoint the line, super helpful!
We are on 3.3.12, but the problematic line comes from the orcid_support_advance plugin version 1.5.1 from the bazaar.
It is this line:
Line 384: if( $old_c->{putcode} eq $new_c->{putcode} )
In this file: /cfg/cfg.d/z_orcid_support_advance.pl
That is actually line 384 in the default file from the bazaar: https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbazaar.eprints.org%2F1138%2F1%2Fepm%2Forcid_support_advance%2Fcfg%2Fcfg.d%2Fz_orcid_support_advance.pl&data=01%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7C6c505b2aaea14ff8784e08d825439424%7C4a5378f929f44d3ebe89669d03ada9d8%7C0&sdata=8gdz%2B0NQTPyTqeETuIw4uW9Y5VyNiN8ZN%2F62r%2F2y%2FVM%3D&reserved=0
I see that this line is actually updated/fixed on GitHub, I guess it just didn't make its way to the Bazaar yet?
Line 384: if( defined $old_c->{putcode} && defined $new_c->{putcode} && $old_c->{putcode} eq $new_c->{putcode} )

I know I mentioned line 379, but that's because I was testing on two different dev servers where that same line was in position 379 on a different server, but also being flagged on commit.
Thanks again!
Tomasz

Hi Tomasz,
I have do deal with these sorts of issues quite a lot. As you probably won't be surprised to hear, I do not know of the top of my head what is causing this issue. However, what typical I do is grep over the archive's cfg and possibly bin directories to see if I can spot any code that may relate to this error. Using the following command you will find any code that could lead to that error on line 379:
grep -rn " eq " EPRINTS_PATH/archives/ARCHIVE_NAME/cfg/ EPRINTS_PATH/archives/ARCHIVE_NAME/bin/ | grep ":379:"
If you don't find anything then it may be worth having a look in perl_lib, lib, flavours/pub_lib. ingredients, site_lib etc. The reason for the "(eval 173)" is probably due to line 379 calling a user-defined function (sub).
If you can tell me the specific version of EPrints you are running I can probably have a look though the code codebase to give some suggestions. There is a good chance that line 379 will be in the core codebase and line 173 will be the line in the archive level user-defined function.
Regards
David Newman

I just finished a CLI script that updates some metadata field values in some items in my repository. Everything is working fine as far as I can tell, values get saved/updated, except that when I run the script, I get this warning every time I do $eprint->commit:
"Use of uninitialized value in string eq at (eval 173) line 379."
Has anyone seen this before? It is rather cryptic and I can't even tell what file it is referring to?
