Subject: php-pear: Invalid argument supplied for foreach() in /usr/share/php/PEAR/Command.php on + XML Extension not found

Date: Wed, 27 Apr 2016 12:36:45 +0200

Package: php-pear
Version: 1:1.10.1+submodules+notgz-8
Severity: grave
Justification: renders package unusable

I discovered I've the same problem described here:
http://serverfault.com/questions/589877/pecl-command-produces-long-list-of-errors
examining horde log files

A long list of
Invalid argument supplied for foreach() in /usr/share/pear/PEAR/...
ending with

PHP Warning:  require_once(/lib/Application.php): failed to open stream:
No such file or directory in /usr/bin/horde-alarms on line 21
PHP Fatal error:  require_once(): Failed opening required
'/lib/Application.php' (include_path='.:/usr/share/php:') in
/usr/bin/horde-alarms on line 21

This also seems to be related with some pear issue not setting horde_dir

Simply running
pear list-all
or any other pear command end up in the same list of
Invalid argument supplied for foreach() in /usr/share/pear/PEAR/...
ending with
XML Extension not found

thanks

Can you send the complete log. I need at least the file and line number.

How have you installed Horde? Using PEAR or apt?

What does aptitude search "php~i" outputs?

> This also seems to be related with some pear issue not setting horde_dir

What does pear config-get horde_dir outputs?

I can't reproduce.

You have a mix of php5 and php7. Ensure you have the corresponding
versions (for xml, ...)

Subject: xml actually missing from php5

Date: Tue, 10 May 2016 12:47:17 +0200

Possibly I got a clue.

There is just a php-xml and no php5-xml or php7-xml packages.

Looking in /etc/php/5.6/mods-available there is no xml.ini while there 
is a xml.ini in /etc/php/7.0/mods-available

After installing php7.0-cli

ivan@caronte:~$ php5.6 xml.php
PHP Fatal error:  Call to undefined function xml_parser_create() in 
/home/ivan/xml.php on line 3

while

ivan@caronte:~$ php7.0 xml.php
doesn't report any error.

I was not able to uninstall php7 due to dependencies.

These and only these packages where automatically installed even if I 
didn't explicitly asked to install php7:
php7.0-common
php7.0-gd
php7.0-json
php7.0-mbstring
php7.0-xml

Trying to purge php7.0-xml says it depends on php-xml but horde depends 
on it.

I'm not completely convinced it is a php/xml problem only.
I'll try to understand what a proper installation of xml should be for 
php5 and see if I can fix it it manually if it's just a matter of 
configuration files but evidently at least there is a problem with php5 
and xml.

BTW I did try to aptitude reinstall php-xml but it didn't help.

You're probably using php5.6 from deb.sury.org? php5 from Debian
doesn't have this binary.

Do you have any third-party repos?

If this is the case, try to install php5.6-xml.

Yes, php5 is going away from Debian testing.

php5 is no more supported in stretch. Why do you need it?

Subject: somehow SOLVED: php5/7 mix

Date: Sun, 15 May 2016 17:31:09 +0200

I sorted it out.
I created a sid lxc container, installed just php-pear and noticed no 
php5 package was installed and pear was working with no error.

I installed horde in the container.
I took note of the php packages that were installed and installed them 
on the machine that was having problems with pear.

No more pear errors but I've found a couple of related problems to the 
transition.

horde was not working for an incompatibility issue in php-text-wiki.
/usr/share/php/Text/Wiki.php suffer from
New objects cannot be assigned by reference
http://php.net/manual/en/migration70.incompatible.php

and I had to change all instances of
=& new
to
= new

Then I got to fix

PHP Warning:  PHP Startup: Unable to load dynamic library 
'/usr/lib/php/20151012/http.so' - /usr/lib/php/20151012/http.so: 
undefined symbol: php_resource_factory_handle_ctor in Unknown on line 0

Installing
php-propro
and
php-raphf

fixed the problem

Finally I removed all php5 packages and everything was still working.


There are some actual problem in the php5 -> php7 transition and while a 
fresh install of php7 works, coming from php5 may not.
Once I got horde working on that box I didn't install any other php 
package but upgrades took in php7 even when it was not installed and 
this most probably caused the problem.

Unless you help me to track down the "transitioning" issue I can't help 
any further on this. At least I solved *my* problem and I documented how.

I hope it helps to find the issue.

I'll issue other 2 separate bug reports for php-common 
(/usr/lib/php/sessionclean) and php-text-wiki 
(/usr/share/php/Text/Wiki.php) shortly.

thanks

CLosing, as this was probably a setup problem.
