Web UI in PHP - support thread

Howdy WebUI Team,

Can you take a peak at my issue on this thread [http://forum.serviio.org/viewtopic.php?f=5&t=6821&p=69075#p69075]

Basically, the webui doesn't seem to want to cross devices. Is this an issue in serviio or the WebUI?

Hey jlcooke,

What type of partition are these mounts?
What PHP version are you running?
Have you tried changing some of the permissions? I've not tested it, but wondering if scandir() is tripping up there.

Screenshots are awesome and proves something is going on. Thanks for including them.

Hey jlcooke,

What type of partition are these mounts?

They're SATA drives mounted as EXT-4 FS.

What PHP version are you running?

PHP 5.4.9 (cli) (built: Nov 22 2012 10:03:10)
Copyright (c) 1997-2012 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies

Have you tried changing some of the permissions? I've not tested it, but wondering if scandir() is tripping up there.

Permissions in the screenshots show 755 for all the top-level folders for the mount points. And inside it's just as permissive.

I tried doing this on my machine:

  Code:

echo '<?php print_r( scandir("/var/ftp/pub") );'|php

and got this:

  Code:

Array
(
    [0] => .
    [1] => ..
    [2] => Backup
    [3] => Mirrors
    [4] => Movies
    [5] => Music
    [6] => Pictures
    [7] => TV
    [8] => Upload
    [9] => sdb1
    [10] => sdc1
    [11] => sdd
)

Screenshots are awesome and proves something is going on. Thanks for including them.

No problem at all. I try to be helpful, and it was just easier to show than to explain.

[mpemberton5]

Great info. So it looks like we should be able to eliminate the partition type and PHP version. Nice. One other thing, is your virtual directory in Apache set to follow symbolic links (FollowSymLinks)? This might be where our problem is.

The Folder Tree code that I use was from a third party and here's the code they use:

  Code:

if( file_exists($base.$dir.$file) && $file != '.' && $file != '..' && is_dir($base.$dir.$file)){
   if(check_for_subdirs($base.$dir.$file)==true){
      echo '<li><a href="#" class="collapsed" rel="'.$dir.$file.'/"></a><a href="'.$dir.$file.'/" class="folder">'.$file.'</a></li>';
   }else{
      echo '<li><a href="#" class="nosubs" rel="'.$dir.$file.'/"></a><a href="'.$dir.$file.'/" class="folder">'.$file.'</a></li>';
   }
}

Since the symbolic links aren't showing, it's not making it past the first if statement. So, run these two commands to see what responses we get:

  Code:

echo '<?php print_r( file_exists("/var/ftp/pub/Music") );'|php

  Code:

echo '<?php print_r( is_dir("/var/ftp/pub/Music") );'|php

One of those are probably failing. Also, try this to see what it gives:

  Code:

echo '<?php print_r( is_link("/var/ftp/pub/Music") );'|php

Great info.

They all return "1".

  Code:

echo '<?php print_r(array( file_exists("/var/ftp/pub/Music"), is_dir("/var/ftp/pub/Music"), is_link("/var/ftp/pub/Music"), ));'|php
Array
(
    [0] => 1
    [1] => 1
    [2] => 1
)


But from apache (http://myhost/mypath/testing.php) I get this:

  Code:

Array
(
    [0] =>
    [1] =>
    [2] => 1
)


Now it gets weird... I tried adding:

  Code:

<Directory /var/ftp/pub>
    Options FollowSymLinks
    AllowOverride None
</Directory>

Then did a graceful restart. No change. Did a hard restart, no change. Changed path to /var/ftp/pub/Music and no change.

Did a few other things in apache conf - I don't recall what - then it returns 1,1,1 and serviio-webui works.

I back out all my changes (in VIM did a 99 'u') and saved, existed, hard restart. The problem doesn't come back.

I am full confused now. Only possible explanation is I had updated the mod_php days (weeks?) ago and it didn't take until a hard restart ... donno.

Thanks for the help!

[mpemberton5]

I've seen enough "unexplainable" issues that it's now the norm.

Glad it's working now.

Cheers!

Can you elaborate further on the bug you've described? Are the sources addedd automatically as RSS and you later need to edit it accordingly? Is maybe a category parameter somewhere to be found?

When "Web Resource" items are added from ServiiDB, WebUI add it but the ResourceType as "RSS Feed" not "Web Resource"
Currently i have to edit it to "Web Resource" and save.

ServiiDB is getting bigger and bigger, easy to add items for custom Serviio plugins

[Swoop]

Ah, ok. Got it.

Tried something. Anyone wants to check?

[Xmantium]

Tried something. Anyone wants to check?

Add as "Live Stream" instead of "Web Resource"

[Swoop]

Thanks for checking. Have to admit it was a quick shot.

At least I'm on the right path, it seems. I'll have a deeper look...

*EDIT* Stupid me. Swapped the values of the variables accidentially... Wanna try again?

[Xmantium]

Success! Thanks Swoop!
Since theres no iOS app for iPad, this is my most used Web app.
Would be cool if Up/Down buttons can be added to Online Library.

Probably a question for Mark: How often does these fixes merge to Marks Official build?

[Swoop]

Awesome, glad to hear

Since I'm no web programmer (and especially a noob with jquery), changes to ServiiDB might take a little while from my side... But as I prefer havin things I use my self working correctly (fun and learning is also given here), I'm happy to support and maintain.

Haven't issued a pull request to Mark with the latest changes as I'm pretty sure there's still something Maybe Mark is willing to add a link of my "dev repo" @Git to the Wiki page, so that the latest can be downloaded before merged into the official build.

Show Logs in Console (only useful for headless or NAS Serviio servers) - Others please do not attempt.

Please make a backup of files you need to modify.

If you are like me, running serviio in an ubuntu headless or in a NAS, and constantly using IOS Devices or ServiioWeb to manage the serviio, also frequently having to use ssh
or WinSCP to review the serviio log, then this post might just for you. This adds serviio Log tab to ServiioWeb and displays current logs once clicked.

1. ServiioWeb/config.php add following to line 12 and modify log folder location as necessary.

  Code:

$log = "/usr/share/serviio/log/serviio.log";

2. ServiioWeb/content.php - replace line 9 with following:

  Code:

if ($tab!="library" && $tab!="metadata" && $tab!="delivery" && $tab!="about" && $tab!="presentation" && $tab!="remote" && $tab!="settings" && $tab!="about" && $tab!="log") {

3. ServiioWeb/index.php - add following line to index.php at line 359

  Code:

<li><a href="content.php?tab=log" rel="indexcontainer"><?php echo tr('tab_log','Log')?></a></li>

4. save following code as log.php in ServiioWeb/view folder.

  Code:

<html>

<head>
<title>Show Serviio Log</title>
</head>
<body>
<?php
include("../config.php");
$file = fopen( $log, "r") or exit('<strong><span style="color:#FF0000;text-align:left;"> Unable to open Serviio log file! </span></strong>');
//Output a line of the file until the end is reached
while(!feof($file))
  {
  echo fgets($file). "<br>";
  }
fclose($file);
?>

</body>
</html>

Wow this is cool, finally no more WinSCP to see what's going on my QNAP Server.

Does it auto refresh?
Would be even cooler it can be formatted, ie view only errors, view my date
About tab should be at the end.

I've been having some issues installing this, here is the area (as seen from the web browser). I am attempting to install the latest version listed on the wiki (1.4beta)

  Code:

The website encountered an error while retrieving http://192.168.1.17/serviio/. It may be down for maintenance or configured incorrectly.
Here are some suggestions:
Reload this webpage later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

My apache.conf:

  Code:

#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned. 
#
# The configuration directives are grouped into three basic sections:
#  1. Directives that control the operation of the Apache server process as a
#     whole (the 'global environment').
#  2. Directives that define the parameters of the 'main' or 'default' server,
#     which responds to requests that aren't handled by a virtual host.
#     These directives also provide default values for the settings
#     of all virtual hosts.
#  3. Settings for virtual hosts, which allow Web requests to be sent to
#     different IP addresses or hostnames and have them handled by the
#     same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "foo.log"
# with ServerRoot set to "/etc/apache2" will be interpreted by the
# server as "/etc/apache2/foo.log".
#

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE!  If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs/2.2/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
#ServerRoot "/etc/apache2"

#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
LockFile ${APACHE_LOCK_DIR}/accept.lock

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 5

Can you confirm you have curl installed? Is there any entries in the Apache error log?

[Xmantium]

@Mark - Definitely think having logs is a brilliant idea, excellent suggestion by npuser for the mod, works great

Im sure you may have some other brilliant ideas to display it on the webui
