Cron job updating currencies is logging a warning... working, but warning

[s_mack]

I've used a currency updating script for ages without problems (I think I wrote it, but I don't recall for sure lol). Anyway, now that I'm finally updating to 1.5.4 I found the current rendition of automatic currency updating but I get a warning logged everytime the cron job runs. It looks like this:

[26-Oct-2015 07:07:01 MST] PHP Warning: session_start(): Cannot send session cookie - headers already sent in /home/smartiep/public_html/test/includes/functions/sessions.php on line 107

I think I get what's happening. The "new" way for the currency updating is to start the file with "require_once('includes/application_top.php');" and I think that tries to begin a session. Since nobody's home, no cookie can be set and it tries to output a "turn on your cookies" message but (again) nobody's home so the message can't output and it throws that warning. That's kind of a guess, but I'm thinking I'm close.

So is calling application_top the wrong way to do it? Or is there a way to treat the cron 'session' as a bot so the cookies aren't tried?

Or am I way off base?

When I wrote the cron script for v160 I started by setting the user agent, but then discovered it was better to simply set a new $loader_prefix to point to a dedicated auto_loader script which skipped starting any sessions.

Actually most of the commits related to implementing this are summarized here: https://github.com/zencart/zencart/c...rency_cron.php

Is this going to be backward applicable to 1.5.4?

A variation of it has been backported into the upcoming v155.

And so far it seems to work fine with this new plugin I made for openexchangerates, inspired from your post the other day: https://www.zen-cart.com/downloads.php?do=file&id=2035

Ah, well then... you're welcome :)

Is 1.5.5 imminent?

Btw, in the instructions for that you say "Login to your Admin, go to Admin->Configuration->My Store, and set the primary currency server to openexchangerates"... primary whatnow? No such setting exists.

And I see you say it can easily be set with a cron in 1.5.5... but what about 1.5.4? The contrib suggests it is compatibel with 1.5.4
