redirect not invoked

Very strange ... I've gone so far as to disable all other modules besides path, page, menu and globalredirect. I've cleared the cache, I've changed the default front page. My aliases work just fine, but nothing will get it to redirect.

I assume this actually does work for somebody, right?

just to confirm - you have mapped node/21 to about and when you go to node/21 (not node/21/ - no trailing slash) it doesn't redirect to the alias?

Correct. No trailing slash. No redirect.

I am running on a current CVS checkout of the DRUPAL-4-7 branch. This is basically 4.7.3, plus any bug fixes that have gone into that branch since the release. This makes it much easier to upgrade ... when 4.7.4 comes out all I have to do is type 'cvs up -dP' in my drupal directory and it's upgraded. No downloading, unzipping, copying files, etc.

I suppose it's *possible* that a change since 4.7.3 breaks your module, but that shouldn't happen on a stable branch.

So I am baffled. For what it's worth the path_redirect module *is* working, as are all other installed modules. I have clean URLs enabled, and I have my modules installed in sites/default/modules. I get the same behavior on my dev site running on Mac OS X and my production server running on Linux.

Any suggestions for helping to debug this?

OK, I have error_reporting = E_ALL & ~E_NOTICE. Turning off all other modules except menu, path, page, and globalredirect makes no difference. If I slip the following code into globalredirect_init() right after the call to drupal_lookup_path() ...

echo "\n";
echo "\$path = '$path'\n";
echo "\$alias = '$alias'\n";
echo "drupal_get_path_alias(\$path) = '" . drupal_get_path_alias($path) . "'\n";
echo "drupal_lookup_path('alias', 'node/21') = '" . drupal_lookup_path('alias', 'node/21') . "'\n";
echo "drupal_lookup_path('alias', 'node/23') = '" . drupal_lookup_path('alias', 'node/23') . "'\n";
echo "drupal_get_path_alias('node/21') = '" . drupal_get_path_alias('node/21') . "'\n";
echo "drupal_get_path_alias('node/23') = '" . drupal_get_path_alias('node/23') . "'\n";
echo "\n";
exit();

... and then access 'node/23' (which is aliased to 'about/cornell'), I get the following ...

$path = 'node/23'
$alias = ''
drupal_get_path_alias($path) = 'node/23'
drupal_lookup_path('alias', 'node/21') = 'about'
drupal_lookup_path('alias', 'node/23') = ''
drupal_get_path_alias('node/21') = 'about'
drupal_get_path_alias('node/23') = 'node/23'

If I access 'node/21' (which is aliased to 'about'), I get the following ...

$path = 'node/21'
$alias = ''
drupal_get_path_alias($path) = 'node/21'
drupal_lookup_path('alias', 'node/21') = ''
drupal_lookup_path('alias', 'node/23') = 'about/cornell'
drupal_get_path_alias('node/21') = 'node/21'
drupal_get_path_alias('node/23') = 'about/cornell'

So it looks like the alias lookup is failing for the current page? Hmmm.

OK, looks like it is a bug in drupal core introduced since drupal 4.7.3 was released. It was introduced by this patch http://drupal.org/node/83234. Backing out this patch fixes the problem.

I submitted an issue for core here http://drupal.org/node/89947.

It appears so to me ... but I'd love to have someone else confirm it.

Fixed by this patch http://drupal.org/node/65493

I believe the conclusion is that it works fine on drupal 4.7.3 (and probably earlier 4.7.x), but not on 4.7.4. Unfortunately, 4.7.4 introduced a bug that breaks the functionality of the globalredirect module. Applying the patch in #14 of http://drupal.org/node/65493 fixes the bug in 4.7.4 that broke this module.

For me, it appears to work for all but the front page. I assume it is still due to http://drupal.org/node/65493, which has not yet been fixed.

In my case, the variable site_frontpage = 'frontpage' and 'node/312' is aliased to 'frontpage'. It will redirect 'http://example.com/node/312' to 'http://example.com/frontpage'. But it won't redirect 'http://example.com/frontpage' to 'http://example.com/'.

Ah ... hmmm ... I see your point. I guess I set up my site_frontpage in admin>settings before deciding how I was going to create the home page (a node, a view ...?).

However, that still doesn't change the fact that globalredirect does not work for the home page. When I change my site_frontpage to 'node/312' and get rid of the 'frontpage' alias, then access node/312, there is no redirect.

I think if http://drupal.org/node/65493 gets fixed that should take care of both scenarios, but I haven't been able to check the latest patch there.
