## Description

Turns out that it is a PHP page that is not working. Also CKEDITOR is not visible.

=> https://github.com/genenetwork/genenetwork2/issues/421 From GitHub

=> http://gn1.genenetwork.org/webqtl/main.py?FormID=annotation The annotations page in GN1
is broken. An exception stack trace is displayed, instead of the annotations page content.

## Info

Lily runs a PHP from 2006(!)

PHP 5.1.6 (cli) (built: Mar 18 2014 20:48:55)
Copyright (c) 1997-2006 The PHP Group
Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies

In guix-bioinformatics we have

```
php     5.6.40  out     /home/gn1/guix-bioinformatics/gn/packages/php.scm:14:2
```

Even if this page is for windows, it is the best description of using PHP:

=> https://www.thesitewizard.com/php/install-php-5-apache-windows.shtml

On lily:

```
AddType application/x-httpd-php .htm .html
```

And Apache:

```
[root@lily conf]# /usr/sbin/httpd -V
Server version: Apache/2.2.3
Server built:   Sep 16 2014 11:05:09
Server's Module Magic Number: 20051115:3

 -D DEFAULT_ERRORLOG="logs/error_log"
 -D AP_TYPES_CONFIG_FILE="conf/mime.types"
 -D SERVER_CONFIG_FILE="conf/httpd.conf"
```

This is similar what we have in Guix GN1. No mention of PHP in either.

For simplicity we may switch to php-cgi

## Test instance of GN1

I started a test instance that listens on port 8044 and is hosted in this dir and started with:

```
gn1@tux01:~/production/gnshare/gn-pjotr-test
. .guix-deploy
gn1@tux01 ~/production/gnshare/gn-pjotr-test [env]$ httpd -f `pwd`/etc/pjotr-test-httpd.conf
```

Restart with

```
pkill httpd ; sleep 1 ; httpd -f `pwd`/etc/pjotr-test-httpd.conf
```

Created a file in web/test/index.html and it displays as

=> http://gn1-pjotr.genenetwork.org/test/index.html

Now a php version

=> http://gn1-pjotr.genenetwork.org/test/index.php

works after setting

```
# CUSTOM: Add PHP 5 parsing (via CGI) handler and action
ScriptAlias /local-bin /gnu/store/213zqkj0r6q41cqarwkz5x568ybhd62b-profile/bin
AddHandler application/x-httpd-php5 php
Action application/x-httpd-php5 /local-bin/php-cgi
<Directory "/usr/local/bin">
    Order allow,deny
    Allow from all
</Directory>

<Directory /home/gn1/production/gnshare/gn-pjotr-test/web/test>
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>
```

## Finding PHP files

All files that have ?php are in ./infoshare. Try

```
gn1@tux01:~/production/gnshare/gn-pjotr-test$ grep '?php' -r > phpfiles.txt
```

they end in .htm and .html so we need to wire that together.

So adding a test in

=> http://gn1-pjotr.genenetwork.org/infoshare/manager/test/index.html

and updating Addhandler to parse .htm and .html works.

```
AddHandler application/x-httpd-php5 php htm html
```

## MySQL connector

We need to tell GN1 to use a more recent mysql connector and drive it over sockets, rather than the web interface. This requires telling it where the INI file is.

This required adding a path for Apache:

```
SetEnv PHP_INI_SCAN_DIR /home/gn1/production/gnshare/gn-pjotr-test
```

and a php.ini file with

```
[Pdo_mysql]
pdo_mysql.default_socket= /run/mysqld/mysqld.sock

[MySQLi]
mysqli.default_socket = /run/mysqld/mysqld.sock
```

Now it remains to replace the mysql connectors with mysqli - a newer driver for PHP. For this we use a translation script from

=> https://github.com/rubo77/php-mysql-fix/blob/master/fix_mysql.inc.php

that gets included with

```
include_once('../includes/fix_mysql.inc.php')
```

At the final step we have to fix CKEDITOR

## CKEDITOR

FF console says:

```
Uncaught ReferenceError: CKEDITOR is not defined
    <anonymous> Ember
```
