Tracy Debugger

Thanks @bernhard - those Breadcrumb and $process methods have been persistent for a while. I think you'll actually need one more update for them to disappear. I "reset" my cache when I was updating Tracy yesterday by going from 152 back to 151, then to 152 and today to 153. Can you remember to check on upgrade to 154 and let me know if the problem still persists please? Thanks.

Thanks @bernhard - is that just the start of things - is it listing virtually everything as new? It is kinda looking like the old cached version was removed somehow in the downgrade / upgrade process. Let's see what others report their experience to be.

@adrian Hi. 

I'm facing a small issue and I'm not sure that this one is relative to Tracy, but I feel that it's better to ask anyway.
I have quite a simple template that outputs page views based on the GET parameters.

Spoiler

<?php namespace ProcessWire;

	bp('template before');
	if (!config('ajax') || !input()->get('post_ids')) {
		wire404();
	}

	$layout->preventOutput(true);
	$dirty_post_ids = input()->get('post_ids');
	$post_ids = implode('|', sanitizer('intArray', $dirty_post_ids));



	header('Content-Type: application/json; charset=utf-8;');
	$data = cache()->getFor('PostViews', $post_ids, 300, function () use ($post_ids) {
		return pages()->getById($post_ids, [
			'getNumChildren' => false,
			'joinFields'     => [
				'phits'
			]
		])->explode(function ($p) {
			return [
				'id'    => $p->id,
				'views' => (int) $p->getViewsCount(3.3)
			];
		});
	});

	echo wireEncodeJSON($data, 0);
	bp('template after');
	$this->halt();

URL of this page is /ua/views/.

The issue is that I have significant and unreasonable leap in memory usage

image.png.b53bb594a76de53db13001323e8dc983.png

The strange thing is that if I change URL ( page name) to something else like v or view I get (if not contains 'views')

image.png.9bb5fdd73198780eb605dd1e6438b52e.png

I have reviewed all the code and did not find anything where occurs 'views'.

I don’t have any idea what can cause it, it's just some kind of mysticism, so I thought maybe it could be an issue with Tracy or Performance Panel. 

Thanks.

Hey @adrian

I've just started using live.js because I'm doing some work in the backend where I need JS/LESS a lot. After getting tired of reloading the browser I thought I'd try browsersync that I recently discovered but it did not work. Then I found live.js and added this to my module:

if(!$this->user->isSuperuser()) return;
if(!$this->config->debug) return;
$this->config->scripts->add('http://livejs.com/live.js');

And this just works!!

The great thing about it is that it even recognizes when my style.less file changed. The great thing here is that it does not reload the browser but only replaces the CSS file (which is crazy because the CSS is parsed via RockLESS on demand, so the server must somehow be involved. Anyway... the style gets updated without reloading the page as soon as I change my LESS file 😎

I thought this would be very easy to include in Tracy. For the frontend it would need to add the whole script tag instead of doing $config->styles->add(), but that would also be simple.

What do you think?

Edit: I understand now how the less-part works. On every poll of live.js the server is involved, so live.js results in lots of requests to your server! I don't think that's a very good option...

@Zeka - sorry, I am not sure - that Performance panel is not my own work - it comes from https://github.com/Zarganwar/PerformancePanel although it hasn't seen any updates in a long time. It would be great if you could figure out where the problem is coming from though if you have the time.

@bernhard - thanks for the idea - but sounds like it's a no go afterall.

Hi @adrian,

Is it possible to switch into a user with the guest role only using the User Switcher panel? I didn't see the default guest user available there so I created a new user with only the guest role but it doesn't appear either.

Or do you know of another way to get the debug bar to appear on a remote site when not logged in? (of course you would never to this on a live site - my site isn't publicly accessible)

Use the logout button on the user switcher panel and it should do what you want.

Thanks! I just had to start a User Switcher session and then the logout button did the trick.

Major new release, thanks in big part to @Robin S for ideas, testing, and feedback.

1. The Console panel now stores it's snippets on disk so they can be backed up, be under version control, and also editable via your external code editor (with direct link from the entry in the Console snippet sidebar). They are stored in either /site/templates/TracyDebugger/snippets/ or /site/assets/TracyDebugger/snippets/

Note that all your pre-existing snippets that were previously stored along with Tracy's module settings will be automatically written to disk when you upgrade to the new version of Tracy.

2. You can define a block of code to be prepended to the snippet when it is saved to disk. For example, Robin is using:

<?php namespace ProcessWire;
//<editor-fold desc="API variables">
/**
 * @var Config $config
 * @var Fieldgroups $fieldgroups
 * @var Fields $fields
 * @var Languages $languages
 * @var Modules $modules
 * @var Page $page
 * @var Pages $pages
 * @var Paths $urls
 * @var Permissions $permissions
 * @var ProcessWire $wire
 * @var Roles $roles
 * @var Sanitizer $sanitizer
 * @var Session $session
 * @var Templates $templates
 * @var User $user
 * @var Users $users
 * @var WireCache $cache
 * @var WireDatabasePDO $database
 * @var WireDateTime $datetime
 * @var WireFileTools $files
 * @var WireInput $input
 * @var WireLog $log
 * @var WireMail $mail
 * @var \ProCache $procache
 * @var FormBuilder $forms
 **/
//</editor-fold>

 

3. The SnippetRunner panel has been removed because it's no longer necessary with the new behavior of the Console panel.

4. The Console panel has a new inbuilt DB backup feature. If checked, it will backup your complete DB. The backups are stored under /site/assets/backups/database/ which is where Ryan's Database Backups module (http://modules.processwire.com/modules/process-database-backups/) stores its backups. It is recommended to install this module to make managing and restoring backups much easier. Backups can be automatically named: tracy-console-2020-04-14-18-23-38.sql or you can specify a custom name in the Console panel if you'd like to set something more meaningful before a major change. Automatically named backups are automatically pruned when there are a set number of backups (default is 25, but is configurable in module settings).

5. The user switcher panel now has the option to use a PW API selector string as a way to determine which users will be listed.

6. There is a new Quicklinks section at the top of the module settings to more quickly get to what you're looking for (code thanks to Robin).

7. Lots of other tweaks, fixes and improvements.

8. New core versions of Tracy and ACE editor.

Please let me know what you think and if you have any problems.

PS - please do a hard reload in your browser to ensure you get the new css and js files.

Hello There @adrian

I am having a strange problem with the wonderfull tracy that started a long time ago but i havent notice until now because i have not used it in a while.

But i am getting errors about:
- The Console Panel
- The ProcesswireInfoPanel
- The ApiExplorerPanel

I will attach screenshots of the errors with some sensitive parts blured out for security.

I hope we can resolve this because i love to use the Console.

I am running:
- Processwire 3.0.153
- Tracy Debugger 4.21.1
- PHP 7.3.16

Hi @EyeDentify - what host are you using? Any chance it's nextcloud or one.com ? https://github.com/nextcloud/server/issues/16752

I can see why you might be getting the error in the PW Info panel, but am confused about the other two. Can you please try disabling the PW Info panel and see if that fixes the other two as well. If it does, then I think we might be able to do a try / catch for the PW Info panel that will fix it.

Finally, do you know why there are two copies of the main Tracy bar - that looks strange to me.

Hi @adrian

Thanks for getting back to me.

I have one.com as host.

I am baffled by the double bar as well, but it says AJAX on the other one.

I tried to disable Info panel but that did not do any difference to the Console error.

Where do i check for the disable_functions list?

If the other bar says AJAX, then that is expected, but your screenshot didn't show that at all, hence my question.

Looking at the error messages for the Console and API Explorer panels more closely, it shows it's actually coming from PW's core FileCompiler.php file on line 384. The PW core uses set_time_limit in many places: https://github.com/processwire/processwire/search?q="set_time_limit"&unscoped_q="set_time_limit" so I think your only decent option is a different host because from what I can tell, one.com doesn't let you enable set_time_limit.

Oki.

Thats unfortunate, because i just changed to one.com 🙂

But everything else seem to work with PW other then the Tracy Debugger.

I get this string:
"disk_total_space, diskfreespace, exec, system, popen, proc_open, proc_nice, shell_exec, passthru, dl"

When i run:
 

<?PHP print_r(ini_get('disable_functions')); ?>

Can you try a few different things for me:

1) Empty the PW trash

2) Do a field export (from the main fields list page)

3) Install the core ProcessPageClone module and click the new "COPY" page list action button

If those all succeed without error, I'll revisit, but otherwise I'll need to update Tracy to be PW 3.x only so that it avoids the FileCompiler completely. That would solve the Console and APIExplorer panel error. The PW Info panel error is due to the Versions List feature trying to check if the system allows runtime modification of max_execution_time so I could conditionally remove or deal with that, but I'd like to make sure those other core PW things work on that host first.

It's also weird how one.com seems to disable set_time_limit / max_execution_time some other way - ie not in disable_functions - make it much harder to detect.

I did the following:
1. Empty trash
2. Did a sucessfull field export

Did not install the ProcessPageClone because it had no install button, it seems to be manual only.
i am not sure how to install it manually.

And PW says i have an newer version of the ProcessPageClone in the system "1.0.4?"

It looks like you already have ProcessPageClone installed - do you have the "copy" button in the Page list action buttons?

Not sure where to go from here - I feel like one.com should be failing on those PW core calls to set_time_limit() as well. Any chance you can give me access to the server - either this one, or another test one at one.com?

Hello Again.

I Get a "Copy" option on any pages under the Root in pagelist.

I am going to uninstall Tracy Debugger and install it again and see what happens.
Cause some things have been acting strange like the image upload issue i postet about a short while ago then went away.

I will think about the server access thing.

      This fieldtype and inputfield bundle was built for storing measurement values within a field, rendering them in a variety of formats and converting them to other units or otherwise modifying them via the API.
      The API consists of a number of predefined functions, some of which include...
      render() for rendering the measurement object, valueAs() for converting the value to another unit value, convertTo() for converting the whole measurement object to different units, and add() and subtract() for for modifying the stored value by the value (converted as required) in another measurement. In the admin the inputfield includes a checkbox (which can be optionally disabled) for converting values on page save. For an example if a value was typed in as centimeters, the unit was changed to metres, and the page saved with this checkbox selected, said value would be automatically converted so that e.g. 170 cm becomes 1.7 m.

      A simple length field using Fieldtype Measurement and Inputfield Measurement.
      Combination units (e.g. feet and inches) are also supported.
      Please note that this module is 'proof of concept' at the moment - there are limited units available and quite a lot of code tidying to do. More units will be added shortly.
      See the GitHub at https://github.com/MetaTunes/FieldtypeMeasurement for full details and updates.

      This module implements the website live chat service from tawk.to. Actually the module doesn't have to do much. It just need to inserted a few lines of JavaScript just before the closing body tag </body> on each side. However, the module offers additional options to display the widget only on certain pages.
      Create an account
      Visit https://www.tawk.to and create an account. It's free! At some point you will reach a page where you can copy the required JavaScript-code.

      Open the module settings and paste the JavaScript-code into the field as shown below. Click "Submit" and that's all.

      Open the module settings
      The settings for this module are located int the menu Modules=>Configure=>LiveChatTawkTo.

      Session Viewer is a module for ProcessWire to list session files and display session data. This module is helpful to display the session data of a specific session or to kick out a logged in user by simply delete his session file. After installation the module is available in the Setup menu.

      The following conditions must be met for the module to work properly:
      Session files
      Session data must be stored in session files, which is the default way in ProcessWire. Sessions stored in the database are not supported by this module. The path to the directory where the session files are stored must be declared in the ProcessWire configuration which is by default: site/assets/sessions.
      Serialize handler
      In order to transform session data easier back to a PHP array, the session data is stored serialized. PHP offers a way to declare a custom serialize handler. This module supports only the default serialize handlers: php, php_binary and php_serialize. WDDX was dropped in PHP 7.4.0 and is therefore not supported by this module as well as any other custom serialize handler. Which serialize handler is actually used you can find out in the module configuration which is available under Modules=>Configure=>SessionViewer.

      Session data
      The session data can be displayed in two different ways. PHP's default output for arrays print_r() or by default for this module nice_r() offered on github: https://github.com/uuf6429/nice_r. There is a setting in the module configuration if someone prefers print_r(). Apart from the better handling and overview of the folded session data the output of nice_r() looks indeed nicer.

      Repeater Easy Sort
      Adds a compact "easy-sort" mode to Repeater and Repeater Matrix, making those fields easier to sort when there are a large number of items.
      The module also enhances Repeater Matrix by allowing a colour to be set for each matrix type. This colour is used in the item headers and in the "add new" links, to help visually distinguish different matrix types in the inputfield.
      Screencasts
      A Repeater field

      A Repeater Matrix field with custom header colours

      Easy-sort mode
      Each Repeater/Matrix item gets an double-arrow icon in the item header. Click this icon to enter easy-sort mode.
      While in easy-sort mode:
      The items will reduce in width so that more items can be shown on the screen at once. The minimum width is configurable in the field settings. Any items that were in an open state are collapsed, but when you exit easy-sort mode the previously open items will be reopened. You can drag an item left/right/up/down to sort it within the items. The item that you clicked the icon for is shown with a black background. This makes it easier to find the item you want to move in easy-sort mode. You can click an item header to open the item. An "Exit easy-sort mode" button appears at the bottom of the inputfield. Configuration
      In the field settings for Repeater and Repeater Matrix fields you can define a minimum width in pixels for items in easy-sort mode. While in easy-sort mode the items will be sized to neatly fill the available width on any screen size but will never be narrower than the width you set here.
      In the field settings for Repeater Matrix you can define a custom header colour for each matrix type using an HTML "color" type input. The default colour for this type of input is black, so when black is selected in the input it means that no custom colour will be applied to the header.
      Exclusions
      The easy-sort mode is only possible on Repeater/Matrix fields that do not use the "item depth" option.
