Tracy Debugger

Recommended Posts

I have latest PW+Tracy installed and when I go to edit a page in the admin I randomly get these notifications

Quote

 404 occurred: /wire/modules/Inputfield/InputfieldFile/InputfieldFile.css.map
 404 occurred: /wire/modules/LanguageSupport/LanguageTabs.css.map

I looked in those folders and there are no map files, not sure why PW is trying to find them or why they would be missing.

This seems occur when I use the "inspector" in the browser to look at elements.

I'm seeing an issue in the Console panel where the indentation (tabs) of saved snippets gets lost when the page is reloaded.

Thanks @Robin S - I am seeing it too - the solution however I am not seeing :) I'll try to take another look tomorrow.

Hi @neosin - this is not related to Tracy. Have a read:

Hey Robin - sorry for the delay on this, but it should now be fixed - please let me know if it works for you.

Thanks. Did you push the changes to GitHub? It's still showing 4.9.31 which is the version I was seeing the issue with.

Oops - sorry, I committed the tag and release for 4.9.32 but not the actual code :)

Try again now!

hey @adrian

I'm working on my DataTables module (that might get renamed to RockGrid btw because I'm experimenting with another grid software :) ) and have 30k sample data pages (basic-page with only title field). When I open such a page in the admin, the page load takes very long (around 10s). I looked at the network tab and saw that the request for initial page load (?id=1017) loads 5.7MB of data.

Cookie: pagelist_open=JSON%5B%221-0%22%2C%221016-0%22%2C%221017-0%22%2C%227-0%22%5D;
wire=...;
wire_challenge=...;
tracyCodeError=ERROR%3A+Maximum+execution+time+of+120+seconds+exceeded+on+line%3A+454+in+D%3A%5Claragon%5Cwww%5Caggrid1%5Cwire%5Ccore%5CWireDatabasePDO.php

When i switch off tracy the page load is instant.

The code for the debug bar is huge:

Any ideas which feature of the panel is causing this behaviour?

Thanks in advance, no hurry at all with this one :)

My guess is that it's the Field List & Values section of the Request Info panel. Can you try disabling just that section and let me know?

Debug Mode is also very slow, but only if Request Info is ON. If Request Info is OFF the Debug Mode is 10ms (first screenshot)

Can you post a screenshot of the contents of the Field List & Value section?

Or maybe you can send me a test version of the module so I can take a look?

I don't see any suspicious information in the panel. Only the HTML code of the debug bar is totally bloated. I think the simplest is to test it on your own. I'm running a fresh dev installation with blank profile and tracy v4.9.33

I've just created a page "data" under /home and added 30k pages with the tracy console:

for($i=0; $i<30000; $i++) {
    $p = new Page();
    $p->template = 'basic-page';
    $p->parent = $pages->get('/data');
    $p->title = uniqid();
    $p->save();
}

Then when I open one of those pages in edit mode the tracy bar takes 10s to load..

@bernhard - could you please let me know how it goes when you disable the "Pages Loaded" section in the Debug Mode panel. This seems to be the main issue at my end.

As a followup @bernhard - I notice that when editing a child with thousands of siblings, all the siblings get loaded, but this doesn't seem to be a Tracy issue - take a look at the PW core Debug Mode panel. I wonder if that's a bug?

Hm, I have "pages loaded: 23"

$config->debug = true/false does not make any difference. Only difference is when I hit the "Disable Tracy" Button in the Debug Bar it instantly becomes fast as usual. I can send you a site profile, maybe that helps :)

Hey @bernhard - sorry for the delay on this - had family in town.

Please try the latest version - it prevents all siblings from being loaded by the prev/next links in the Request Info panel (which was a bug I hadn't noticed). This should actually make a huge different to anyone using Tracy on a page with a lot of siblings - can't believe I didn't come across this till now - thanks for bringing it to my attention.

One caveat - if you are running AOS with the "Add links to edit previous and next pages" feature enabled you might still have problems, although it shouldn't affect page load speed. I have made a note here:

Thanks @adrian, that solves the issue and my pw admin is lightning fast again :) I've experienced slower loading with tracy several times, but I was not able to identify when it occured. Maybe this was the reason, I'll keep an eye.

BTW: Where do I find the prev/next links?

In the Request Info Panel. The name is a View link and the ID is an Edit link.

Don't forget to also take a look at it when editing a field, template, or module - shows all the settings for those in addition to the normal sections. Can be very handy for certain dev needs.

@bernhard - could you please check the latest version for me - I left out "include=all" for the prev/next links in the last commit. Everything still seems fast here, but would appreciate it if you could confirm it's ok at your end too please?

Hi everyone - looking for some feedback. The Tracy core has just introduced an option to dump objects using the __debugInfo() magic method which PW also supports.

It changes this:

to:

image.png.bfb0aa40445b6cd37b4bb37ac1a068e6.png

 

What I am wondering is whether to make using __debugInfo() the default or not. And also wondering how often you guys might want to switch between one vs the other - in other words, will it be ok as a config setting, or do you think it's something that should be easier to change on-the-fly?

Thanks for any input.

Would you mind adding some additional information to your question? What is the difference between the two? What would be the pros/cons?

I use dumping a lot but I use only very basic features I guess. Most of the information in the first screencap does not seem to be very helpful to me (at least most of the time, or at least not yet). The second looks cleaner to me, but what I do not like is that "template" is a string and not a ProcessWire\Template as shown in the first pic (though that's a tiny detail and i guess dumping $page->template would show the correct classname?).

[2min later] To me, the second looks cleaner and more helpful.

You'll know more about this than me, but my understanding is that what is available in a dump from __debugInfo() depends on what the developer of the class makes available in the method. So if that method in a class was quite limited in what it made available (either intentionally or not intentionally) then the Tracy user potentially misses out on a lot of relevant information.

To give a silly example, if I do this in a class...

public function __debugInfo() {
    return ['Nothing to see here.'];
}

...then dumping an instance of it will be useless.

It looks like most of the __debugInfo() work is done in the dedicated WireDebugInfo class. If you think that Ryan has covered everything that anyone could ever need here then I guess shorter/tidier is better. But if you have doubts I'd rather get all the data as per the status quo than be wondering about what might have been overlooked.

      A simple module to enable easy navigation between the public and the admin side of the site. After installation a green bar will appear to the upper side of the screen, containing a few navigation elements and displaying the PW version number.
      Heavily inspired by @apeisa's great AdminBar (Thanks!). I needed a bit simpler tool for my projects and as a result, this was made. Available on GitHub .

      I've created a small module which lets you define a timestamp after which a page should be accessible. In addition you can define a timestamp when the release should end and the page should not be accessable any more.
      Github: https://github.com/Sebiworld/PageAccessReleasetime
      Usage
      PageAccessReleasetime can be installed like every other module in ProcessWire. Check the following guide for detailed information: How-To Install or Uninstall Modules
      After that, you will find checkboxes for activating the releasetime-fields at the settings-tab of each page. You don't need to add the fields to your templates manually.
      Check e.g. the checkbox "Activate Releasetime from?" and fill in a date in the future. The page will not be accessable for your users until the given date is reached.
      If you have $config->pagefileSecure = true, the module will protect files of unreleased pages as well.
      How it works
      This module hooks into Page::viewable to prevent users to access unreleased pages:
      public function hookPageViewable($event) { $page = $event->object; $viewable = $event->return; if($viewable){ // If the page would be viewable, additionally check Releasetime and User-Permission $viewable = $this->canUserSee($page); } $event->return = $viewable; } To prevent access to the files of unreleased pages, we hook into Page::isPublic and ProcessPageView::sendFile.
      public function hookPageIsPublic($e) { $page = $e->object; if($e->return && $this->isReleaseTimeSet($page)) { $e->return = false; } } The site/assets/files/ directory of pages, which isPublic() returns false, will get a '-' as prefix. This indicates ProcessWire (with activated $config->pagefileSecure) to check the file's permissions via PHP before delivering it to the client.
      The check wether a not-public file should be accessable happens in ProcessPageView::sendFile. We throw an 404 Exception if the current user must not see the file.
      public function hookProcessPageViewSendFile($e) { $page = $e->arguments[0]; if(!$this->canUserSee($page)) { throw new Wire404Exception('File not found'); } } Additionally we hook into ProcessPageEdit::buildForm to add the PageAccessReleasetime fields to each page and move them to the settings tab.
      Limitations
      In the current version, releasetime-protected pages will appear in wire('pages')->find() queries. If you want to display a list of pages, where pages could be releasetime-protected, you should double-check with $page->viewable() wether the page can be accessed. $page->viewable() returns false, if the page is not released yet.
      If you have an idea how unreleased pages can be filtered out of ProcessWire selector queries, feel free to write an issue, comment or make a pull request!

      Thanks to the great Pro module "RepeaterMatrix" I have the possibility to create complex repeater items. With it I have created a quite powerful page builder. Many different content modules, with many more possible design options. The RepeaterMatrix module supports the cloning of items, but only within the same page. Now I often have the case that very design-intensive pages and items are created. If you want to use this module on a different page (e.g. in the same design), you have to rebuild each item manually every time.
      With this proof of concept I have created a module which adds the feature to copy a repeater item to the clipboard so that you can paste this item to another page with the same repeater field. The module has been developed very rudimentarily so far. It is currently not possible to copy nested items. There is also no check of Min/Max. You can also only copy items that have the same field on different pages. And surely you can solve all this more elegantly with AJAX. But personally I lack the deeper understanding of the repeaters. Also missing on the Javascript side are event triggers for the repeaters, which would make it easier. Like e.g. RepeaterItemInitReady or similar.
      it would be great if @ryan would implement this functionality in the core of RepeaterMatrix. I think he has better ways to implement this. Or what do you think, Ryan?
      Everybody is welcome to work on this module and improve it, if it should not be integrated into the matrix core. Therefore I put it for testing and as download on GitHub: https://github.com/FlipZoomMedia/InputfieldRepeaterMatrixDublicate
      You can best see the functionality in the screencast:

      Hi,
      Please take a look at this:
      https://templatemag.com/demo/Good/
      The upper nav bar, including dropdowns like "pages" and "portfolios", what do you call this whole thing? At first I guess it's called "dropdown nav bar", but seems not.
      AND of course, what's the simplest way/module to achieve this in PW?
      Thanks in advance.

      Hey, I'm new and I created a simple module for tagging pages because I didn't found a module for it (sadly this is not a core feature). This module is licensed under the GPL3 and cames with absolutly no warranty at all. You should test the module before using it in production environments. Currently it's an alpha release. if you like the module or have ideas for improvements feel free to post a comment. Currently this fieldtype is only compatible with the Inputfield I've created to because I haven't found  an Inputfield yet, that returns arrays from a single html input.
