Any reports from the front lines? Is the development environment still plagued by broken/conflicting/missing dependencies in ClearOS 6.6.0? What about in the upcoming ClearOS 7?

I just fired up a 32-bit ClearOS 6 instance and it looks like the "clearos-epel" repo won't work as is. The development environment needs a whole bunch of packages from EPEL, so that's a show stopper. To get things working, I changed the following two lines in /etc/yum.repos.d/clearos-epel.repo:

From:

#baseurl=http://download.fedoraproject.org/pub/epel/$releasever/$basearch

mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-$releasever&arch=$basearch

To:

baseurl=http://download.fedoraproject.org/pub/epel/$releasever/$basearch

#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-$releasever&arch=$basearch

Perhaps EPEL changed their 32-bit mirror handling? I raised a but in the tracker - https://tracker.clearos.com/view.php?id=3681

What is broken or missing?

Any reports from the front lines? Is the development environment still plagued by broken/conflicting/missing dependencies in ClearOS 6.6.0? What about in the upcoming ClearOS 7?

Is the development environment fixed in ClearOS Community 6.6.0 32-bit or are there still broken/missing dependencies?

Thanks a lot. I will go through the document.

I'll write up a developer document on the topic. More to come!

Thanks for the information. It helped me a lot to understand the functionality of form submission and storing the data. But have a query regarding the configuration file.

In ClearOS, the changes are written directly to the configuration file.

You will need to create a similar configuration file for your daemon.

-- Does it mean every app has their separate configuration file? If so, then in which location shall we create the configuration file and how to establish relationship between the configuration file and daemon?

If there is only one configuration file in which all changes/settings are mentioned, then how the changes (can be a modification or additional change) will be recognised by daemon ?

Also, i have understood very little about how to enable(start) and disable(stop) the working process of an app. You mentioned to checkout controllers/server.php file and i did so. Arguments are being passed to constructor but there is no indication of enabling and disabling the process (or, it can be a mistake of my understanding). Can you please provide more details about it?

Yup, the above PPTP example will show you the way.

Means, how can i execute a command in shell internally with the help of app which will enable or disable a process.For example, enabling/disabling a cron script by executing command internally through an app.

For normal daemons (in /etc/rc.d/init.d), follow the PPTP app as an example. In general, you can execute commands using the Shell class. Here's an example:

#!/usr/clearos/sandbox/usr/bin/php

<?php



///////////////////////////////////////////////////////////////////////////////

// B O O T S T R A P

///////////////////////////////////////////////////////////////////////////////



$bootstrap = getenv('CLEAROS_BOOTSTRAP') ? getenv('CLEAROS_BOOTSTRAP') : '/usr/clearos/framework/shared';

require_once $bootstrap . '/bootstrap.php';



///////////////////////////////////////////////////////////////////////////////

// D E P E N D E N C I E S

///////////////////////////////////////////////////////////////////////////////



use \clearos\apps\base\Shell as Shell;



clearos_load_library('base/Shell');



///////////////////////////////////////////////////////////////////////////////

// M A I N

///////////////////////////////////////////////////////////////////////////////



$shell = new Shell();

$shell->execute('/bin/ls', '/etc');

$output = $shell->get_output();



print_r($output);

Thanks for the answers Peter. I will checkout the PPTP app.

Do you mean how do you start and stop a daemon?

I'm not sure what you mean here. What app are you building?

Hi Debashis,

We will continue to chip away at the developer documentation as time permits. It's a high priority, so it won't stay stagnant.

1) How apps establish connection with core function after installation? What is actually executing internally?
4) Where the form datas are being stored after submission?

I'm going to answer 1 and 4 together.

Take a look at the PPTP server app. It's simple to understand, but still has enough complexity to make it a good starting point. Ultimately, a web form submission runs a bunch of API calls. For example, when a user submits the PPTP settings through the web form, the CodeIgniter framework sends the information to the API with the following block of code in the controller/settings.php file:

    $this->pptpd->set_remote_ip($this->input->post('remote_ip'));

    $this->pptpd->set_local_ip($this->input->post('local_ip'));

    $this->pptpd->set_wins_server($this->input->post('wins'));

    $this->pptpd->set_dns_server($this->input->post('dns'));

    $this->pptpd->reset(TRUE);

The API (in library/PPTPd.php) does the actual configuration change. In other projects, configuration changes are written to some kind of internal database, and then the configuration file is re-generated. In ClearOS, the changes are written directly to the configuration file.

2) How to enable(start) and disable(stop) the working process of an app after installation?

Do you mean how do you start and stop a daemon? If so, take a look at the /var/clearos/base/daemon/pptpd.php file (if PPTP is installed) as an example. You will need to create a similar configuration file for your daemon. Next, follow the controllers/server.php example in the PPTP app. If you get stuck, just let me know -- this answer should really be a standalone document (not just a handful of sentences!)

3) How to enable / disable a core functionality with the help of an app?

I'm not sure what you mean here. What app are you building?

Keep the questions coming, I'm more than happy to help!

Hello everyone,

I have gone through the below mentioned urls to get familiar with clearos app development process and developed 'hello world' app by following the instructions.

www.clearfoundation.com/docs/developer/apps/start
www.clearfoundation.com/docs/developer/framework/start


However, i want to learn more like:
1) How apps establish connection with core function after installation? What is actually executing internally?
2) How to enable(start) and disable(stop) the working process of an app after installation?
3) How to enable / disable a core functionality with the help of an app?
4) Where the form datas are being stored after submission?

I tried to know the above process but found nothing useful. Can you provide any tutorial or url so that i can have idea about all these information and the rest?
Or, can you suggest how can i start core app development process?

My bad. Update the the "policy_manager" app:

If we had our continuous integration system running, that would not have happened!

Thanks. It fixed the issue.

Documentation has been updated here
http://www.clearfoundation.com/ClearFoundation-Blog/423-clearos-6-developer-tools-now-available.html

yum upgrade

yum --enablerepo=clearos-developer,clearos-epel install clearos-devel

You can also use this.

yum --enablerepo=clearos-current,clearos-dev,epel install clearos-devel

Peter,

How can i view the first version of AD connector?

Hi DavidAdams and Arnold.

The first version of the Active Directory Connector is available, but I would wait for the updated version that is coming out shortly (with the release of ClearOS Professional Beta 3). If you send a quick note to me (pbaldwin@clearcenter.com) with your ClearCenter account name, I'll make sure there's an evaluation subscription added to your account -- I'm not sure the self-serve evaluation will be available in Beta 3.

not avaible?

Same here, I click on the link in the web interface and it takes me to the marketplace with nothing available. Pity as we are in the process of a WAN based active directory config and the ability to have the same user base across all ClearOS locations would be good.

Something else that would be nice and I can't seem to find a mention of if/when it is going to happen is Central Management. We have 15 systems scattered across Europe and the Far East and having to check for updates and patches one by one is time consuming and error prone.

Yes, indeed that is the problem. Solved now.

I never had this problem before. So i suppose with beta 2 the character set has changed???

Hi Marcel, this might help

Today i played a bit with srpm's and rpm's. I saw something weird.

Length: 663543 (648K) [application/x-rpm]

Saving to: âlibevent-devel-2.0.10-2.clearos.i686.rpmâ

i mean the â in front and after of libevent-devel-....... Any idea why this happens?

Thank you :bow:

Here's a better yum command so that you don't pull in the "testing" (read: bleeding edge) RPMs:

yum --enablerepo=clearos-current --enablerepo=clearos-dev --enablerepo=epel install clearos-devel

oh.., good new's.

Thank you for the quick reply. :cheer:

Hi Marcel,

If you have the beta1-to-beta2 upgrade, you should be able to run:

yum --enablerepo=clear* --enablerepo=epel* install clearos-devel

And then continue with the documentation from http://www.clearfoundation.com/docs/developer/development_environment I'm not 100% sure if this still works especially since we have upgraded everything to upstream's version 6.2. I don't have my devel environment up and running right now for a quick sanity check. Regardless, the devel environment will be yum-installable in beta 2 and I think we might green light the release in the next 24-48 hours :-)

Status update please?

Thanks for the update Peter.

I was really keen to get started on this

I'm (hopefully) finishing up this topic with Shad today. We started the conversation this morning but was interrupted by a product meeting. We have another meeting in a few minutes and hopefully we can get back on track after that call.

Any update on this subject?

I have some time this weekend to "prutsen" with RPM's and SPEC files but i have to re install my devel environment.

Peter Baldwin wrote:

Update - Download No Longer Available :-(

Wow. We were expecting maybe a dozen people to create this development environment, but over 200 have taken the plunge. That put too much bandwidth strain on the staging download server, so we are making plans to use our usual mirror system. Please stay tuned.

Wow over 200... ClearOS is populair!

The Clearfoundation has to expand their server capabilities.

Good catch. I updated the document using version 6 and the extra line in .rpmmacros is no longer necessary. It's better to have it there to cover both versions though :-)

Good point Nick! i've added it to the environment variables section
