PHP 5.2 not compatible

[barbuslex]

Hi,

I have this error on PHP 5.2 :

Call to undefined function array_replace_recursive() in //lib/Minz/Configuration.php

array_replace_recursive() is available on PHP 5.3. In FreshRSS documentation it is writtent compatible with PHP 5.2.1+.

Can you help me ?

Ok, this should be easy to fix. I will make a patch.

[barbuslex]

Ok thanks !
Maybe there are other inconsistencies I did not go further in the script.

[Alkarex]

@barbuslex Here is a patch. Could you please test #1059 ?

[barbuslex]

@Alkarex I've tested.

Another error now :

Fatal error: Cannot redeclare recurse() (previously declared in /lib/lib_rss.php:20) in /lib/lib_rss.php on line 20

I've tried to change recurse() by recurse_arr() (_arr for array replace recursive) and i get the same error :

Fatal error: Cannot redeclare recurse_arr() (previously declared in /lib/lib_rss.php:20) in /lib/lib_rss.php on line 20

[barbuslex]

In your modification in /lib/lib_rss.php,

I have replace :

function recurse($array, $array1) {
    foreach ($array1 as $key => $value) {
        if (!isset($array[$key]) || (isset($array[$key]) && !is_array($array[$key]))) {
            $array[$key] = array(); //create new key in $array, if it is empty or not an array
        }
        if (is_array($value)) {
            $value = recurse($array[$key], $value); // overwrite the value in the base array
        }
        $array[$key] = $value;
     }
    return $array;
}

By :

if (!function_exists('recurse')) {
    function recurse($array, $array1) {
        foreach ($array1 as $key => $value) {
            if (!isset($array[$key]) || (isset($array[$key]) && !is_array($array[$key]))) {
                $array[$key] = array(); //create new key in $array, if it is empty or not an array
            }
            if (is_array($value)) {
                $value = recurse($array[$key], $value); // overwrite the value in the base array
            }
            $array[$key] = $value;
        }
        return $array;
    }
}

And it work's !

But now, in installation steps (url : /p/i/index.php?step=2) i have this error :

Parse error: syntax error, unexpected '{' in /lib/password_compat.php on line 10

The line in question is (/lib/password_compat.php line 10) :

namespace {

[Alkarex]

Ah, yes indeed. The password form requires PHP 5.3.3, and the inclusion of this code needs to check for cryptAvailable() first.

On line https://github.com/FreshRSS/FreshRSS/blob/dev/app/install.php#L133

if ($password_plain != false && cryptAvailable()) {

I will make a patch later.

[barbuslex]

With this fix i stay on step 2 with this html alert error in top of the form :

Veuillez corriger les erreurs avant de passer à l’étape suivante.

[Alkarex]

It looks like for some reason you have been able to select form as a login method. It is a bug if this option is available for < PHP 5.3.3. Could you please try again by selecting HTTP or nothing for login?

[Alkarex]

P.S. Loging with HTTP requires that you make a password protection with your Web server, e.g. a .htaccess with Apache:

AuthUserFile /xxx/.htpasswd
AuthGroupFile /dev/null
AuthName "FreshRSS news"
AuthType Basic
Require valid-user

[Alkarex]

Indeed, there is a bug https://github.com/FreshRSS/FreshRSS/blob/dev/app/install.php#L684 which pre-selects form login even when not available. I will fix it.

[Alkarex]

I have made another attempt in #1059 (not tested).
I may have to install a virtual machine with PHP 5.2 to test...

[barbuslex]

I have succefully install FreshRSS with this fix.
But it's impossible to enable authentication. Non authentication mode is very dangerous :(

[Alkarex]

Yes, form-based login requires PHP 5.3.3+. With older version, you can use HTTP login. See #1055 (comment)
(This is the login system I use myself)

[barbuslex]

Yes but if i want generate a rss feed aggregated must not authentication in this case.

[Alkarex]

HTTP login is less convenient for that indeed, but there are different possibilities such as making some URL rewriting for those URLs or a proxy. (I do that for my Shaarli, of which I only expose an RSS feed, the rest being with an HTTP password).

Until November 2016, you can also use Persona for login #1052

On a related topic, here is a reference to a discussion from a year ago about PHP versions #789 (comment)

Out of curiosity, on which distribution do you run PHP 5.2? (It is interesting to get some feedback from users to help setting minimal requirements).

[barbuslex]

I will try persona.

I use 000webhost.com hosting ^^

[royalterra]

@barbul..... 000 is a share hosting with very bad performance one and is hack several times. Really if you use free hosting like that why you post bugs?

[Alkarex]

In any case, my plan is more or less to have one last version of FreshRSS supporting PHP 5.2, then to set the minimal version to PHP 5.3.3 for some time (for CentOS 6, which stops in Q2 2017, but we may not wait that long).

[Alkarex]

@barbuslex Maybe your hosting plan allows to change the PHP version. Did you check?

[barbuslex]

Yes i know it's just for test this plan. I will migrate to better hosting plan later.
Not possible to change PHP version in free hosting :)

[royalterra]

That host not allow changes and is full of limitations and bugs for that is hack several times a year. Still I got emails from the admin every time go down. really a hosting can be free but you choice the worse free hosting in internet

[barbuslex]

Yes ^^ i have migrate to GoogieHost with last version of PHP.

[Alkarex]

Just to close the topic here, can you please confirm, @barbuslex , that #1059 works with your PHP 5.2?

[barbuslex]

Yes it work's fine
