Upgrade Jaxon-PHP from 2.0-beta.24 to 2.2.6

[tom-lp-at]

Hello again,
i go back until Version 2.0-beta.28 (i had 2.0-beta24 before) and there it works. With the update to 2.0.0 all the responses are empty. I followed the examples (btw: the online example show´s an error) with no success.
I cant find a document where is described what is to do by changing from 2.0-beta to stable :(
I checked the commit from the 2.0.0-Verison of jaxon-core and realize that there is the step to Armanda. Could it be that the jaxon-codeigniter is outdated ? The last version is after the commit of jaxon-core 2.0.0, but i can not find a glue to bring it back to work >= 2.0.0....

Hello again,
i recognized that only some functions are working. Only the functions with a return $this->response are working. With 2.0-beta.24 all response methods are working and give responses - also without a explicit return $this->response.
It seams that i stuck on this beta release :(

Hi,
In the case you have some classes which do not return the jaxon response, you have to add your response to the returned reponse by yourself. You will then need to edit the the jaxon controller provided in the CodeIgniter plugin.
https://github.com/jaxon-php/jaxon-codeigniter/blob/master/app/controllers/jaxon/Process.php

    /**
     * Callback after processing a Jaxon request.
     *
     * @param object            $instance               The Jaxon class instance called
     * @param string            $method                 The Jaxon class method called
     *
     * @return void
     */
    public function afterRequest($instance, $method)
    {
        $xResponseManager = jaxon()->getResponseManager();
        $xResponseManager->clear();
        $xResponseManager->append(jaxon()->getResponse());
    }

[tom-lp-at]

Dear feuzeu,
thx for your response. It seams that my problem is a little bit deeper :(
i wrote this sample code:

<?php
 
 namespace Jaxon\App;
 use Jaxon\Sentry\Armada as JaxonClass;

 class welcome_ajax extends JaxonClass { 

         public function index() {
            log_message('info','Bin hier');
            $this->response->assign('testtom','innerHTML','HALLLO');
            return $this->response;
        }
 }

 ?\> 

The Method index() will is not called, but i get a (empty) response, if i entered in the JavaScript-Console of the browser :

Jaxon.App.welcome_ajax.index();
false

so - in my opinion, that JS-Callback-function is build, but it call not the index()-method on the php-side :(
In the Developertools i see the request to process.php with the right parameter:

jxncls      | Jaxon.App.welcome_ajax
jxnmthd     | index
jxnr        | 1570964591097

but the logs show no entry of my message, so it seams that the PHP-Function is not called....

(it´s a complete new build up installation of CI 3 with all defaults and last stable versions....)
i implement your suggestion (not needed in the test, but may be later) :

<?php

Hi Tom,

I suggest first to use the beforeRequest() to make sure the right method is called.

    public function beforeRequest($instance, $method, &$bEndRequest)
    {
        log_message('info', "Jaxon class name is " . get_class($instance) . " and method is $method");
    }

You can then make sure the response and response manager return the same output.

    public function afterRequest($instance, $method)
    {
        log_message('info', "Jaxon response output is " . jaxon()->getResponse()->getOutput());
        log_message('info', "Jaxon response manager output is " . jaxon()->getResponseManager()->getOutput());
    }

The outputs must contain the instructions you added in your Jaxon class.

[tom-lp-at]

Dear Feuzeu,
thanks for your response. Jaxon-php didn´t :)
the 'BeforeRequest' is not passed:

[feuzeu]

Hi,

Seems like the library is not able to find the invoked Jaxon class.
Have you setup the autoloading?

[tom-lp-at]

Dear Feuzeu,
before i recocnized that CI-3 has its implementation of autoloading, i put this lines into index.php (=> the old stil ).

/*
 * --------------------------------------------------------------------
 * LOAD THE BOOTSTRAP FILE
 * --------------------------------------------------------------------
 * 
 * And away we go...
 */
require_once BASEPATH.'../vendor/autoload.php';
require_once BASEPATH.'core/CodeIgniter.php';

The direction seams to be the right one, but the javascript functions are build up, so i can call in the console the Jaxon.App.welcome_ajax.index() ?!?! So in the initialization he found the *.php-files in the /jaxon/classes directory. But if he likes to call them, they seams to be ignored/not found....
There is the point i am lost :(

The access-log from nginx :

[16/Oct/2019:11:56:55 +0200] "POST /jaxon/process HTTP/1.1" 200 23

no error is logged on the call...
the config.php

$config['app'] = array(
    'classes' => array(
        array(
            'directory' => rtrim(APPPATH, '/') . '/jaxon/classes',
            'namespace' => '\\Jaxon\\App',
            // 'separator' => '', // '.' or '_'
            // 'protected.' => array(),
        ),
    ),
);
$config['lib'] = array(
    'core' => array(
        'language' => 'en',
        'encoding' => 'UTF-8',
        'request' => array(
            'uri' => 'jaxon/process',
        ),
        'prefix' => array(
            'class' => '',
        ),
        'debug' => array(
            'on' => true,
            'verbose' => true,
        ),
        'error' => array(
            'handle' => false,
        ),
    ),
    'js' => array(
        'lib' => array(
            // 'uri' => '',
        ),
        'app' => array(
            // 'uri' => '',
            // 'dir' => '',
            'extern' => false,
            'minify' => false,
            'options' => '',
        ),
    ),
);

i added a log_message in the process.php and it will be passed:

[feuzeu]

I don't know how to include Jaxon classes in the CI-3 autoloading config.
Try to ask Jaxon to use the composer autoloader.

    public function index()
    {
        ∕∕ Use the composer autoloader
        jaxon()->useComposerAutoloader();

        $this->jaxon->onInit(function ($instance) {
            $this->initInstance($instance);
        });
        $this->jaxon->onBefore(function ($instance, $method, &$bEndRequest) {

[feuzeu]

It most likely means Jaxon is not able to create an instance of the invoked class.
It is the case if following code returns null in the index() method.

$instance = $this->Jaxon->instance($_POST['jxncls']);

Are you able to instantiate the Jaxon\App\welcome_ajax class in index()?

[tom-lp-at]

not with "Jaxon" but with "jaxon" :

    {
		log_message("info","in index() of Process.php");
		jaxon()->useComposerAutoloader();

		$instance = $this->jaxon->instance($_POST['jxncls']);
		log_message("info","Instance = ".var_export($instance,true));
	....

the result is NULL - you are right...

so i inserted the creation of a instance

$welcome = new Jaxon\App\welcome_ajax;
		log_message("info","Welcome = ".var_export($welcome,true));

and it comes something back:

INFO - 2019-10-16 15:07:41 --> Welcome = Jaxon\App\welcome_ajax::__set_state(array(
   'response' => NULL,
   'rqFactory' =>
  Jaxon\Sentry\Factory\Request::__set_state(array(
     'instance' => NULL,
  )),
   'pgFactory' =>
  Jaxon\Sentry\Factory\Paginator::__set_state(array(
     'instance' => NULL,
     'nItemsTotal' => 0,
     'nItemsPerPage' => 0,
     'nCurrentPage' => 0,
  )),
   'xJaxonCallable' => NULL,
))

the NULL´s are OK ?

with a uppercase "J" it comes to this error :

<p>Severity: Notice</p>
<p>Message:  Undefined property: Process::$Jaxon</p>

Hi,
You're right, there's a typo in my previous comment. It's $this->jaxon->instance($_POST['jxncls']);, sorry.
The first reason I can see why Jaxon cannot find your classes is they are not located where expected.
Check if the Jaxon library is able to export your PHP classes to Js.

[tom-lp-at]

hello,
it seams so - i can call in the Javascript-Console the "Jaxon.App.welcome_ajax.index()".
All my tests depends on the "knowledge" that this JS-Functions are build and i can call them. But the Functions are not entered/called and the response from the call is empty....
My question is: why the get not called ? The Process.php seams to be passed (except the init ?!).
As i understand, the Process.php calls the Jaxon-Classes, isn´t it ?
I placed two log_message into Jaxon.php in library:

if (! defined('BASEPATH')) exit('No direct script access allowed');

[tom-lp-at]

Hello,
regarding your comment "is not located where expected" i log the entrys in jaxonSetup()

INFO - 2019-10-17 16:28:16 --> BaseURL = http://ci-test.linuxprofi.at / BaseDir = /home/tom/entwicklung/CI-Test-Jaxon

I recognised that the Library tells $sentry that the Jaxon-JS-Librarys are stored in '/home/tom/entwicklung/CI-Test-Jaxon/jaxon/js' - but there is no files. In the documentation is written that the jaxon-libraries are taken from a cdn (what is right - i see it in the Javascript-Developer-tools).
I placed the jaxon.core.js & jaxon.debug.js in this directory, but it has no effect....
Wrong way ?
kr Tom

[feuzeu]

Hi,
For example, your welcome_ajax PHP class should be located in the APPPATH/jaxon/classes/ dir, which in this case is /home/tom/entwicklung/CI-Test-Jaxon/application/jaxon/classes/.
The corresponding js class should also be declared in the generated js code.

Jaxon = {};
Jaxon.App = {};
Jaxon.App.welcome_ajax = {};
Jaxon.App.welcome_ajax.index = function() {
    return jaxon.request(
        { jxncls: 'Jaxon.App.welcome_ajax', jxnmthd: 'index' },
        { parameters: arguments }
    );
};

The /home/tom/entwicklung/CI-Test-Jaxon/jaxon/js/ dir contains the generated js files.

[tom-lp-at]

Dear Feuzeu,
ok - it seams we come closer to the problem. The Directory .../CI-Test-Jaxon/jaxon/js exists and has the right permissions.
SeLinux is disabled - no errors in nginx-logs, but : there are no generated files.
I checked my running project with jaxon-php-v2.0-beta24 and there are also no generated files....
Could it be that this "feature" of cached JS-Files comes after the V2.0-beta24 ?
That could be the point why the project didnt run with newer versions.... :(
Could you give me a glue where i can investigate the generation of the JS-Files ?
(to be honest - i thought that the JS-Code is only send out with the browsercode, so i don´t miss the generated JS-Files :( )
One further question to understand something more : If the code is not generated, why can i call the function in the JS-Console and have a (empty) jxnobj-response to it ? Are this two different parts ?
thx for your time & kr Tom

[tom-lp-at]

Dear Feuzeu,
in the transmitted code to the browser, i found the part you mentioned :

    }

     */
    command.response = jaxon.tools.queue.create(jaxon.config.responseQueueSize);
    while((obj = jaxon.tools.queue.pop(jaxon.response)) != null)
    {
        jaxon.tools.queue.push(command.response, obj);
        delete obj;
    }
    if(confirm(msg)){jaxon.ajax.response.process(command.response);}else{jaxon.confirm.skip(command);jaxon.ajax.response.process(command.response);};
    return true;
};

jaxon.dom.ready(function() {
    jaxon.command.handler.register('cc', jaxon.confirm.commands);


jaxon.command.handler.register("jquery", function(args) {
    jaxon.cmd.script.execute(args);

Jaxon = {};
Jaxon.App = {};
Jaxon.App.welcome_ajax = {};
Jaxon.App.welcome_ajax.index = function() {
    return jaxon.request(
        { jxncls: 'Jaxon.App.welcome_ajax', jxnmthd: 'index' },
        { parameters: arguments }
    );
};


/* ]]> */

so the code is send, but not stored in the /jaxon/js-directory ....
kR Tom

[feuzeu]

Hi Tom,
I finally found what's going wrong. Since a few versions now, dots and underscores can be used as separators in javascript class names.
As an unforeseen drawback of this feature, underscores can no more be used in Jaxon class or directory names. That's the cause of this issue. When processing your request, the Jaxon library looks for the Jaxon\App\welcome\ajax class, instead of Jaxon\App\welcome_ajax.

So you need to rename your classes and remove underscores. Unfortunatelly, there's no simple way for me to fix this issue now.

I should have been able to find this earlier. Sorry.

[feuzeu]

Regarding the generated js code, it is inserted into the HTML code because you have this in your configuration.

    'js' => array(
        'lib' => array(
            // 'uri' => '',
        ),
        'app' => array(
            // 'uri' => '',
            // 'dir' => '',
            'extern' => false,
            'minify' => false,
            'options' => '',
        ),
    ),

Change the extern and minify options to true, and set the dir and uri options with a directory path on your server and the corresponding url. Make sure the directory is writable.
The js code will then be exported to a file in this dir, which will then be loaded from the main page.

[tom-lp-at]

Dear Feuzeu,
sensationell - with the changing of "welcome_ajax.php" to "welcomeajax.php" (the classname in it too). The Response is working !!!! 👍
In the other project's it would be a heavy change to the code to remove all the "_" ....
Stupid question : Is there a other option to allow the underscore in method-names ? Let´s say every method of my code had a "_" in it :(
Of course, i can change to upper-/lowercase names, but there are thousands of method´s :(

kr Thomas

[tom-lp-at]

I searched a little bit around and the issue with "_" seams to be a new one. But, as i understand its for functions and variables that starts with a underscore. I could not find a proposal for functions or variables with a "_" in the name....
Could it be that the method/class names are replaced/use the "_" in the whole string as separator and not only on the starting position ? Could it be a way to replace/use only the starting "_" ?
kr Thomas

[tom-lp-at]

I test it with methods with a "_" in the name and they works ! 👍
So the only job will be the change of the Classnames - that should be possible with the usage of KDE´s KFileReplace....
Thank you for your time !!!
And last but not least - i love Jaxon-php again :D
kr Thomas

[tom-lp-at]

One further question before i close. Is it useful to generate the Jaxon-JS-Files on the filestore ? Bring it some performance benefits or something else ?
kr Thomas

[feuzeu]

One further question before i close. Is it useful to generate the Jaxon-JS-Files on the filestore ? Bring it some performance benefits or something else ?
kr Thomas

Yes, it has many benefits.
Browsers can cache the file allowing pages to load faster, and the library does not parse the classes to generate the js code when the file already exists.

[tom-lp-at]

Thank you again - i give it a try :)
best wishes - issue closed....
