Headers already sent

this fix is already in bootstrap.inc as:

    $parts = parse_url($base_url);
    if (!isset($parts['path'])) {
      $parts['path'] = '';
    }
    $base_path = $parts['path'] . '/';

on the other hand, aggregator2 is still crapping out on a refresh sometimes, I suspect it's in the aggregator2 code somewhere (perhaps getting the feed information via http outputs a header somehow?).

Conclusion - i'm changing this to an aggregator2 module bug.

Okay, turns out the refresh bug is in fact in aggregator2, i've attached a patch that fixes it.

Commentary:

It's not so critical because normally the refresh is handled by the cron, and the refresh is actually working, it just fails at the end with the drupal_goto() call. The problem is in the calls to flush() immediately before various sleep commands included in the feed parsing. I don't know why those flush commands are there, but they are generating headers that show up when I check with a header_sent (they seem to be empty headers). I tried putting ob_start() and ob_end_clean() around the flushes but that didn't work (because it was outputing headers, not content), but then i converted the flushes to ob_clean() and that solved it. I suspecting those flushes were there in error (you use the flush() trick if you're trying to use sleep as a way of animating output, i'm guessing they just got put in by copying from some sleep() function example).

adixon,

Thanks for researching and resolving this issue. It has been hounding me for awhile.

My previous attempts in diagnosing the problem revealed that ob_get_length() was zero immediately before executing

drupal_goto('admin/aggregator2');

at the end of content_import_admin_refresh_feed(), yet the "headers already sent" message persisted.

I am beginning to suspect that this is a PHP 5 issue because I don't remember this occurring with PHP 4.x.

In any event thanks again.

Could you attach the correct files let me to replace the error one?

I have no idea about coding.

Do I have a chance to get all the stuff working ok if I UPGRADE?
