With >=app-eselect/eselect-php-0.8.1, to enable PHP support

needs to read

but

  APACHE2_OPTS="......... -D PHP"

unification in context of the advent of PHP 7.x.

With that change, guard "<IfDefine PHP>" in file

has a chance to actually pull in PHP support.

Without updating APACHE2_OPTS, websites could end up serving
PHP code (include configuration files with passwords)

Vague.

We'd like to be pretty certain that PHP application server is going to
"actually" do that.

That would mean there is an additional (local) security problem.

Do you have any timeline in place for the change happening in tree (in
particular for stable users).

Such a change should really be avoided if possible. Would it be
possible to have a conditional approach where either one can be used,
or maybe set the new variable/defin if the old one is used?

Hi Sebastian,

to be honest I was very upset when I first stumbled upon this problem.
And yes I only found about it when my apache webserver started to
deliver php source code instead of the real sites.
Doing such a change without getting in contact with me as apache
maintainer before the change was done is very... eh... impolite at best.

Kind regards
Lars

In particular we should avoid both of these scenarios:
1. Stable users make a change now which breaks their existing config
(because the change isn't deployed to stable yet).
2. Stable users get the news item today, and the change six months
later after they've forgotten about it.

I'm not sure whether either applies in this case.

Maybe I'm thinking things too difficult, why not just define both -D
PHP and -D PHP5 in the transition period and suggest this config for
any change?

Well, if this is the common outcome, then I dare say it's very bad,
at least. Gentoo was never the distribution people could seriously
consider stable, and it not uncommon for breakages like this to happen.
But still, it's very bad if an upgrade is going to suddenly cause
webserver to disclose script sources rather than running it.

While of course the sole fact that this can happen is a complete
disastrous design failure, we can't really do much about it or cause
people to stop using such misdesigned software. Nevertheless, I think
it would be reasonable to at least try to reduce the intentional
breakage to bare minimum.

Therefore, I think you should really work on some kind of backwards
compatibility for people using '-D PHP5' that would prevent those kind
of issues at least for some migration period. With big fat warnings for
people who run it.

And while at it, in additional to news item, this should likely follow

Because it mostly just defers the problem.

If the desire is to move away from PHP5 then I would suggest to force
a failure when starting Apache, if PHP5 is defined when PHP is required.

Ie. fail closed.

I can be talked into supporting the idea to only print a warning when
PHP5 is set and to not fail (no source served) for some period of
time until which the forced failure starts, if PHP5 is still set.

Don't fail open, fail closed. Since manual interaction is required
some people will forget or overlook it, and will get a failure.

I would introduce the failure right away, but maybe a warning will
make some happy who would otherwise have gotten a failure.

I don't want to be too prescriptive with the solutions.  However,
clearly /some/ kind of orderly transition is necessary.  News before,
an elog, etc.  And that news needs to be timely - not 12 months before
stable mysteriously breaks one day, unless it is safe to make the
change before the update.  I'd leave it up to the maintainer to decide
whether it is more work to coordinate the timing around all the
communications or to have a more graceful transition so that the
timing isn't as critical.

The problem is really two-fold with the new eselect-php.

For future compatibility (to not have this happen again with say
PHP8), the PHP team changed the symlink created by eselect to be
libphp.so instead of the current libphp${MAJOR}.so.

The user must also reselect with `eselect php set X`, even for the
current PHP versions and not just 7.

mjo explored the option of "<IfDefine PHP5>Define PHP</IfDefine>" but
that is apache-2.4+ only.

If we wanted a "compatibility" layer, it would be the same section
repeated until 2.4 was the only version available.  That might confuse
users even more.

afaics this only affects users using the mod_php variant of PHP and not
any fcgid or fpm solution. I think this should be mentioned.

I wasn't able to come up with something that worked on apache-2.2 and
was backwards-compatible or failed "off."

The apache module name for PHP changed with php-7.0. This forces a big
change in 70_mod_php.conf, and a corresponding change in eselect-php
(which must be run once before anything will work). The problem is to
come up with an apache-2.2 config that works for new 5.6 users, 5.6 ->
7.0 eselect switchers, and new 7.0 users. Someone always gets screwed.

If anyone has a concrete idea that works better, it's not too late to
change it.

Add code to init script and service file to check the config before
starting the program, and react if PHP5 is still set.

Which init script? It's only "bad" to have PHP5 set if the user has
installed >=eselect-php-0.8.1, and run it at least once. You don't want
to e.g. kill working php-5.x installations for people who have apache
keyworded ~arch.

For Apache.

So pkg_postinst for >=eselect-php-0.8.1 should say something, but
ideally also the invocation - but I don't know if eselect-php is also
code or only data managed by eselect?

IMO that would be a much lesser evil than serving source in another
case, as long as it is clear how to unkill (sed s,PHP5,PHP,) the setup.

The pkg_postinst is already there. The eselect-php routines are bash
code so theoretically we can do anything we want. How do people feel
about making eselect-php spit out a warning every time the apache2
module is messed with?

It wouldn't be that simple; at the very least, those people would have
to keyword eselect-php, upgrade it, run it, and fix their config. To do
that properly would make eselect-php a dependency of the new apache, and
that's wrong.

All PHP applications are written by the sort of people who will tell you
to put a config file in the public DocumentRoot, and that's not easy to
fix as the system administrator. Those virtual hosts should really
really really really really be wrapped in <IfModule> statements.

Perhaps grep for -DPHP5 or if -DPHP is missing in the conf.d and shout
then as part of the "eselect php set apache2 X"?

My understanding (which could be wrong) is that this update will break
things even if the user never runs eselect php afterwards.  I can't
tell you the last time I touched the php eselect module, because major
updates to php are rare.

I was going to say "no, everything should keep working" but I decided to
test a fresh upgrade before sticking my foot in my mouth. Now I know
what people are complaining about.

If you've never touched 70_mod_php5.conf, portage will remove it when
you upgrade eselect-php. That does break an existing installation until
you've run `eselect php...` and munged -DPHP5 to -DPHP. What I intended
was for 70_mod_php5.conf to stick around until you've had a chance to
deal with the configuration change. In that case everything keeps
working until after you've run eselect.

I may be able to fix that by simply including the old 70_mod_php5.conf
for backwards compatibility.

I just pushed a new revision with this fix. In eselect-php-0.8.2-r1,
we ship both the new 70_mod_php.conf and the old 70_mod_php5.conf. The
latter comes with a big warning at the top of it, stating that it is for
backwards compatibility only.

The way this should work for upgraders is:

  * You currently have php-5.x eselected, -DPHP5 defined, and a symlink
    to libphp5.so in your apache2 modules directory.

  * You upgrade eselect-php.

  * The way we handle the module symlink and conf.d definition has
    changed, but the new eselect won't touch your old libphp5.so
    symlink, and you still have -DPHP5 defined.

  * With 70_mod_php5.conf still around, everything keeps working
    exactly as it did before the eselect-php upgrade.

  * If you try to use `eselect php ... apache2`, it will create a NEW
    symlink, under the new scheme. Nothing else happens. Hopefully
    this convinces you to read the elog or apache config.

  * If you define both -DPHP5 and -DPHP, you can get problems. Don't do
    that?

  * If you switch from -DPHP5 to -DPHP, the new 70_mod_php.conf kicks
    in, and the new scheme gets used, and your eselect choice will
    start working. Now you can delete 70_mod_php5.conf.

tl;dr it should keep working until you try to eselect and "it doesn't do
anything." Then hopefully you try to figure out why and realize you need
to update to -DPHP. But until then your current PHP keeps running.

If you had trouble with the upgrade, first of all -- sorry, and could
you please give the new revision a try? This upgrade should only be
annoying, not fatal.

Cool, sounds like a great idea to me.

I guess we don't need a news item any more then?

Exactly the same with me.

Upgraders still have a problem, but a much less severe one. After
upgrading eselect-php, further attempts to `eselect php set apache2`
will appear to have no effect, because the old 70_mod_php5.conf is
loading the old symlink to libphp5.so. There are a few options:

1. Leave things as is, and tell people what to do (read the elog) if
   they hit this situation.

2. Proceed with a news item that basically says "read the elog."

3. I could try to hack some magic into eselect-php to detect whether or
   not you have -DPHP5 set. Something simple, like grepping /etc/conf.d
   /apache2 for "PHP5". In that case we could omit a notice.
   This one simultaneously makes the most sense and feels like the
   biggest hack.

+1 for 3.

You can remove the hack in a year or so. I think most important is a 
good user experience. If this requires a hack because the design of the 
tools give you no other choice than be it.

Done in recent eselect-php:

  $ sudo eselect php set apache2 1
  !!! Warning: The apache2 configuration has changed in this
  !!! Warning: version of eselect-php. You should define "-D PHP"
  !!! Warning: and not "-D PHP5" for apache. The module is now
  !!! Warning: loaded by 70_mod_php.conf (was 70_mod_php5.conf).
  !!! Warning: After you have changed "-D PHP5" to "-D PHP",
  !!! Warning: you should remove 70_mod_php5.conf to eliminate
  !!! Warning: this warning. Until you have done so, your eselect
  !!! Warning: choices for apache2 will have no effect.

  Please restart apache for the changes to take effect.

Users may get that warning more than once if we reinstall
70_mod_php5.conf, but it's harmless and less hacky than grepping
/etc/conf.d/apache2.

I think we can forego the news item? Thanks for the suggestions.
