# GN1 annotation page broken
## Tags
* assigned: zsloan, pjotrp
* priority: high
* status: testing
* type: bug
* keywords: GN1, genenetwork1, annotation, from github
## Tasks
* [ ] Fix PHP view
* [ ] Fix CKEDITOR
## 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
Server loaded: APR 1.2.7, APR-Util 1.2.7
Compiled using: APR 1.2.7, APR-Util 1.2.7
Architecture: 64-bit
Server MPM: Prefork

forked: yes (variable process count)
Server compiled with....
-D APACHE_MPM_DIR="server/mpm/prefork"
-D APR_HAS_SENDFILE
-D APR_HAS_MMAP
-D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
-D APR_USE_SYSVSEM_SERIALIZE

-D DEFAULT_PIDLOG="run/httpd.pid"
-D DEFAULT_SCOREBOARD="logs/apache_runtime_status"
-D DEFAULT_LOCKFILE="logs/accept.lock"
-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
=> https://stackoverflow.com/questions/28823252/installing-php-5-3-29-from-sources-on-ubuntu-14-with-apache-2-module
=> https://www.bobulous.org.uk/coding/apache-php-cgi.html
## 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
```
Turns out that lily URLs were hard-coded in the source. So, that was an easy fix. There are still some complaints about CSS links missing in the browser console, but until someone sees a difference I does not need fixing.
Changing the status to testing now.
## Updating production
The source code is now in sync on 'master' branch. Now I need to update guix-bioinformatics package to set up the container correctly with Apache httpd.conf.
