Module for developer and debug tools for use with laminas-mvc applications.

Laminas Developer Tools

🇷🇺 Русским гражданам

Мы, участники Laminas, родились и живем в разных странах. У многих из нас есть друзья, родственники и коллеги как в России, так и в Украине. Некоторые из нас родились в России. Некоторые из нас живут в России. У некоторых бабушки и дедушки сражались с фашистами во Второй мировой войне. Здесь никто не поддерживает фашизм.

У одного из нас есть украинская родственница, которая спаслась из дома вместе с сыном. Поезд задержался из-за бомбежки на дороге впереди. У нас есть друзья, которые прячутся в бомбоубежищах. Мы с тревогой ждем весточки от них после воздушных налетов, которые беспорядочно наносят удары и попадают по больницам, школам, детским садам и домам. Мы не берем это из каких-либо СМИ. Мы наблюдаем это напрямую.

Вы доверяете нам достаточно, чтоб использовать наши программы, и мы просим вас довериться нам вновь. Мы нуждаемся в помощи. Выходите и протестуйте против этой бесполезной войны. Остановите кровопролитие. Скажите "Нет войне!"

🇺🇸 To Citizens of Russia

We at Laminas come from all over the world. Many of us have friends, family and colleagues in both Russia and Ukraine. Some of us were born in Russia. Some of us currently live in Russia. Some have grandparents who fought Nazis in World War II. Nobody here supports fascism.

One team member has a Ukrainian relative who fled her home with her son. The train was delayed due to bombing on the road ahead. We have friends who are hiding in bomb shelters. We anxiously follow up on them after the air raids, which indiscriminately fire at hospitals, schools, kindergartens and houses. We're not taking this from any media. These are our actual experiences.

You trust us enough to use our software. We ask that you trust us to say the truth on this. We need your help. Go out and protest this unnecessary war. Stop the bloodshed. Say "stop the war!"

PHP 8.0 support

Feature Request

Q	A
New Feature	yes

Summary

To be prepared for the december release of PHP 8.0, this repository has some additional TODOs to be tested against the new major version.

In order to make this repository compatible, one has to follow these steps:

• Modify composer.json to provide support for PHP 8.0 by adding the constraint ~8.0.0
• Modify composer.json to drop support for PHP less than 7.3
• Modify composer.json to implement phpunit 9.3 which supports PHP 7.3+
• Modify .travis.yml to ignore platform requirements when installing composer dependencies (simply add --ignore-platform-reqs to COMPOSER_ARGS env variable)
• Modify .travis.yml to add PHP 8.0 to the matrix (NOTE: Do not allow failures as PHP 8.0 has a feature freeze since 2020-08-04!)
• Modify source code in case there are incompatibilities with PHP 8.0

ApplicationConfig unescaped

Hi.
Broken page because the code is displayed unescaped.
It seems there is a problem in ConfigCollector::unserializeArray().

See zendframework/zendframework#6166

Resolution is to wait for the next release (2.2.8 and 2.3.2) and then remove the patched code at https://github.com/zendframework/ZendDeveloperTools/blob/9f93faecc1c9c31b8af67491f0e706e75b1f85bf/src/ZendDeveloperTools/Listener/EventLoggingListenerAggregate.php#L120

Page for background-collection

this PR sets up a page, where you can view former collected toolbar entries by accessing the route /zdt-background-reque.

Known Bugs:

• It’s ugly
• If you scroll to the page’s bottom, it’s horrible to read the bar’s content
• it uses a very high amount of memory

Missing:

• Tests
• Some cookie-stuff to assign and filter the requests (that’s, what the :uuid in the route is for)
• A way to cleanup the cache
• Review

Feature: CSS Markup

Would it be possible to add all the CSS Markup into a CSS File so that when you view the source in a browser you don't have to scroll to find your code?

Right now I have to scroll past all the ZDT CSS Markup in the source to look at my own source and it can be quite annoying at times.

in the application config ,i have a route its type is 'Zend\Mvc\Router\Http\Chain', this type need a parameter 'route_plugins', so i new it in the application config.
but in the \Zend\Mvc\Router\RoutePluginManager, the initializer propery store some closures. so when the application config is serialized, the error happend.

i think we need a method named makeObjectProperySerializable in the class Collector\ConfigCollector

Tooltip in icons to show info or show title

I believe a good addition to ZendDeveloperTools, is to add a tooltip so that when you mouse over any icon or information, it displays information about what that is talking (or title of that information).
Presented the ZendDeveloper for some friends, but they felt a bit of trouble to use, because they do not know what were some of the information displayed.

If the hover, it showed the title of that information, the example below, I think it would be easier for anyone to notice. And this extender title display all items in this wonderful bar.

DeveloperTools fatal error when using named Adapters

Bug Report

Summary

I was using named Adapter in my database configuration as shown in https://docs.laminas.dev/tutorials/db-adapter/#configuring-named-adapters:

    'db' => [
        'adapters' => [
            'Application\Db\ApplicationAdapter' => [

How to reproduce

Expected behavior

Wrong data type returned in implementation of serialization methods

Psalm uncovered wrong types returned by serialization methods.

Before 2.9.0 can be tagged this issue and other psalm complaints must be addressed.

Use with ZF2

The project page (url below) starts with the line "Module for developer and debug tools for working with the ZF2 MVC layer". (url: https://github.com/zendframework/ZendDeveloperTools )

The line makes you wonder if the module is compatible (or applicable for) with in ZF3 MVC projects.

I feel this should be changed to show that this module will work in ZF2 and ZF3, perhaps like this:
"Module for developer and debug tools for working with the ZF2 MVC layer, works with ZF3"

Whitespace Bleed

The toolbar bleeds 8 new lines into each response, which can cause issues (if, for example, you try and build a zip file then those 8 new lines will be included in that zip file causing it to be invalid).

Could this be fixed?

CSS box-sizing

I know, that this is not an error at all, but:

If I use bootstratp CSS, for example - there present this style definition:

/* bootstrap.css #259 */
* {
  -webkit-box-sizing: border-box;
     -moz-box-sizing: border-box;
          box-sizing: border-box;
}

So with this borders I've got some irritating behavior when mouseover on some ZendTools button and popup content showed over button and I'm trying move my mouse to this content - it disappears!

Because of borders adds some extra space and mouseover event brokes.
Works if I move mouse over green arrow :)

I know, that this is behavior of bootstrap.css, but if u will add this:

#zend-developer-toolbar {
...
    -webkit-box-sizing: content-box;
    -moz-box-sizing: content-box;
    box-sizing: content-box;
...
}

then problem will be fixed on all possible CSS frameworks, I think.

Sorry for my english.
Thx

All my requests return json, either a html output to replace the current toolbar or just a json object of the reports would be nice.
I looked throw the code but could not figure out where all the reports come together and injected in the view so i can hijack it and do something with it.

In HTML5, the <head> element can be omitted. The zend-developer-tools css requires it.

• I was not able to find an open or closed issue matching what I'm seeing.
• This is not a question. (Questions should be asked on chat (Signup here) or our forums.)

Provide a narrative description of what you are trying to accomplish.

Code to reproduce the issue

In HTML5, the <head> element can be omitted. The following code will validate as HTML5:

<!DOCTYPE html>
<html>
<title>Title of the document</title>

<body>
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
</body>

</html>

However, ZendDeveloperTools\Listener->injectToolbar() requires it to work

$injected = preg_replace('/<\/head>/i', $style . "\n</head>", $injected, 1);

Expected results

Styles should be displayed in the html document even if there is no <head> html element when the document is html 5 document.

Actual results

html document does not include zend-developer-tools required css, if <head> element is missing from the layout.

Toolbar hidden will soon not be remembered because of cookie settings

Bug Report

Q	A
Version(s)	2.4.0

Summary

Firefox warns about the laminas-hidden cookie. In specific, it references the following documentation: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite#samesitenone_requires_secure

The problem is that the cookie will be rejected by future browser versions.

Current behavior

laminas-hidden cookie is set with SameSite=None and without secure.

I believe the code responsible for this behaviour is located here: https://github.com/laminas/laminas-developer-tools/blob/2.4.x/view/laminas-developer-tools/toolbar/toolbar.js

How to reproduce

Enable the laminas-developer-tools toolbar. Visit your website. Observe the console output of your browser.

Expected behavior

No warnings should be thrown.

Since not all websites under development are served over a secure connection, I propose setting SameSite=Lax.

Incorrect Content-Lenght after toolbar injection

When the Content-Lenght is set by some module for an text/html asset (think asset manager for static html files in a data directory served via standard resolver :-) ) the Content-Lenght header will be incorrect after the Toolbar is injected. This results pages in half loaded.

adding the following at https://github.com/zendframework/ZendDeveloperTools/blob/master/src/ZendDeveloperTools/Listener/ToolbarListener.php#L163 will solve this

    if (function_exists('mb_strlen')) {
        $contentLength = mb_strlen($injected, '8bit');
    } else {
        $contentLength = strlen($injected);
    }

    $response->getHeaders()
        ->addHeaderLine('Content-Transfer-Encoding',   'binary')
        ->addHeaderLine('Content-Length',              $contentLength);

I don't actually need the toolbar on static pages, and i realize this only affects development environments, still I though "lets create a record of this...".

I also wonder why the Response object does not do this automatically...
