Errors validating Repository in Openarchive

Software Support
1

Good afternoon.

We are trying to validate our OJS repository in Openarchive, however it is giving us 3 bugs that we have not been able to solve. They are the following:

Checking ListRecords response

REQUEST http://iberoamericasocial.com/ojs/index.php/index/oai?verb=ListRecords&from=2017-04-17T18:26:44Z&until=2017-04-17T18:26:44Z&metadataPrefix=oai_dc GET
FAIL Server failed to respond to the ListRecords request (HTTP header values: status=500 Internal Server Error, age=0, lifetime=0, is fresh:=)

Checking for version 2.0 specific exceptions

REQUEST http://iberoamericasocial.com/ojs/index.php/index/oai?verb=ListRecords&metadataPrefix=oai_dc&from=2002-02-05&until=2002-02-06T05:35:00Z GET

FAIL Error in parsing XML response to exception request: verb=ListRecords&metadataPrefix=oai_dc&until=2016-04-17T09:05:37Z

Could someone help us?

Thank you very much.

Hi @jmbarroso,

Check your PHP error log for details.

Hi @asmecher

this is my PHP error log:

Hi @jmbarroso,

Those “Warning” messages are cosmetic and can be ignored – but what is that garble at the end? I’ve never seen something like that before in a PHP error log.

Thanks for the support @asmecher

I do not know what that garble means. It appeared when I activated the debug in config.inc.php. This is the correct way to view PHP errors, right?

Thank you for your patience, I’m new to this and there are many things that I still do not understand well.

Hi @jmbarroso,

The error log is usually somewhere in your hosting directory, but the details will depend on your service provider. See e.g. How do I find my PHP error log?.

Thanks @asmecher,

I have the error.log in the logs folder of my server, but the error.log file is empty. :frowning:

I imagine there should be some mistake in him, right?

Sorry, and thanks for your patience.

Hi @jmbarroso,

I’m afraid you’ll have to check with your service provider to find out where error messages are logged, and if that’s the file, why they aren’t being recorded there.

Hello,

I’m a brother of @jmbarroso. We study the problem. The binary code show by php was gzipped message. After disabling gzip / cloudfire we could see:

Fatal error</b>:  Uncaught Error: Using $this when not in object context in /srv/www/iberoamericasocial.com/www/ojs/lib/pkp/classes/oai/OAIUtils.inc.php:59

Reviewing the file, we changed the line 48 of OIAUtils.inc-2.php from:
function UTCtoTimestamp($date, $checkGranularity = true) {
to
function UTCtoTimestamp($date, $checkGranularity = false) {

Maybe there is any configuration error or a code bug, not sure. After this patch the OAI Validator passes successfully all the tests

Where should we report this issue ?

Thank yoy very much

Hi @jmbarroso/@i5513,

What version of OJS are you running?

Hi @asmecher,

is the 3.0.2.0 version.

Regards!

Hi all,

Thanks for the details. I’ve added a fix – see issue 2782, particularly the first patch (“Fix kludgey use of $this in static calls”), which will need to be applied in the lib/pkp subdirectory. The older code works for me, but isn’t well written, and probably your version of PHP is stricter about such things.
