Description Christopher Head 2013-03-10 19:05:15 UTC
Behaviour differs between "emerge -uatvDN @world" and asking to emerge a specific package individually. Example:

# emerge -uatvDN @world

These are the packages that would be merged, in reverse order:

Total: 3 packages (1 in new slot, 2 reinstalls), Size of downloads: 28,847 kB

The following USE changes are necessary to proceed:
 (see "package.use" in the portage(5) man page for more details)
#required by virtual/httpd-php-5.4-r1, required by www-apps/mediawiki-1.20.3, required by @selected, required by @world (argument)
=dev-lang/php-5.4.8 apache2

(observe that I have dev-lang/php installed with the cgi USE flag but not the apache2 USE flag, and that virtual/httpd-php-5.4-r1.ebuild depends on the OR of php[apache2], php[cgi], and php[fpm]).

Now when I try to emerge just www-apps/mediawiki on its own, it doesn't complain; rather, it lets me go ahead and update it!

Comment 2 Christopher Head 2013-03-10 19:12:57 UTC
In fact, even when all the depending packages are up to date, "emerge -uatvDN @world" still complains, though it changes to complaining about virtual/httpd-php being depended upon by www-apps/drupal instead of www-apps/mediawiki (I have both installed).
Comment 3 Christopher Head 2013-03-10 19:23:06 UTC
Interestingly, after adding dev-php/pecl-uploadprogress to package.provided (it would otherwise depend on dev-lang/php[apache2], and I have absolutely no use for it since it doesn't work in Lighttpd Drupal anyway), the problem goes away. Yet emerge never printed any message about dev-php/pecl-uploadprogress when complaining about the needed USE flag changes; it insisted that virtual/httpd-php was at fault even though that virtual's dependencies were very happily satisfied with dev-lang/php[cgi].

This sounds like an issue with the dependency calculation of Portage. There is nothing wrong with the virtual, as it blindly depends on any web-related SAPI of PHP. Pecl-uploadprogressbar however strictly depends on apache2 since it does not work without it.

My suggestion is that drupal only conditionally depends on pecl-uploadprogressbar.
Comment 5 Christopher Head 2013-03-11 07:03:27 UTC
I suspect this is indeed a bug in Portage (in the output printing, not in the actual dependency enforcement, note—it stopped asking for the php[apache2] once pecl-uploadprogress was package.provided, the issue is that it’s printing out that it needs it due to www-apps/mediawiki via virtual/httpd-php, which is false).
