Tracy Debugger

Recommended Posts

Hey @Zeka - I have a fix for you, although I think you'll have to do it in your module - I haven't figured out how to do it from the Tracy side yet.

Add this to the top of your TemplateFile::render hook:

    if(strpos($event->object->filename, 'TracyDebugger') !== false) return;

I haven't had a good look (too busy atm), but if someone else has an idea on how Tracy could remove/cancel a TemplateFile::render hook when running code via Console/Snippet Runner I'd be happy to do it from Tracy's side instead.


PS - here's another possible option instead of the above:

    if(str_replace('site/assets/cache/FileCompiler/', '', $event->object->filename) !== $this->wire('page')->template->filename) return;

This will ignore your hook if the template file from the hook event is different to the template file for the current page. I am not sure about this in your situation, but if it works it's obviously more flexible than just blocking Tracy template files.

Quite a noob question about WireExceptions. 

Have two exceptions ( output of PW logs) :

exceptions 2018‑03‑02 15:34:22 | admin | http://test.local:4000/shop/Method | TemplaterLayout::render does not exist or is not callable in this context (in D:\laragon\www\test\app\wire\core\Wire.php line 519) 

modules | 2018‑03‑02 15:31:10 | admin |http://test.local:4000/shop/ | Failed to ready module: Templater - Method TemplaterLayout::setTemplateFile does not exist or is not callable in this context

The first one generates full report like

The second one is only visible in PW logs panel without full report.

Why are they handled in different ways? 

Thanks.

Hi @Zeka

I am not totally sure about why, but from what I can tell errors that show up in PW logs, but are not picked up by Tracy because the error is triggered in PW before Tracy is loaded. I have asked @ryan about adding a special method to allow loading Tracy earlier - he initially sounded supportive, but he hasn't gotten back to me since my follow up request. I think it's  only ever a problem when doing something in init() so it doesn't happen that often.

How did you go with those snippets to fix the Console panel problem?

@adrian Do you have a future request on git, so I can support it? 

As for Console panel, both of your snippets didn't work. I have sent you a PM.

No - it was a PM that I sent to Ryan - I didn't want to bug him about it publicly. I just tried to add you to the PM, but it said you couldn't be added - not sure, I haven't used that feature before.

Thanks for the module link - I'll take a look.

Hi @adrian, just wondering if Tracy should create the "tracy-debugger" permission on install to save the user creating it manually?

Only reason I didn't do this for Tracy is that I doubt many people use this option - just figured it was one extra permission to clog up the list that perhaps only a very small percentage of users will actually apply to a role in their system.

Does that seem fair enough? Or are lots of you actually using to to give Tracy access to non-superusers? If so, I can add to the install routine.

Yes, that's fair enough. I don't give anyone but myself access to Tracy, but need it sometimes when testing from non-superuser roles on a live server. But not all that regularly, and it doesn't take long to create the permission manually.

That's what the User Switcher panel is for :) Have you tried it out?

You can even test as a guest user by clicking the Logout button and the debug bar will still display.

Hi @adrian,

I just installed the MarkupLoadRSS module and all kinds of stuff started happening with Tracy. :D

First, I noticed that I can't place the mouse in the snippet name field. As soon as you click in the text box the cursor is immediately placed back in the console window. This is fresh PW.94 localhost install and Tracy.25 is the only other module installed.

Second, I now get the following:

Exception: Objects returned by MarkupLoadRSS::getIterator() must be traversable or implement interface Iterator in /var/www/tgp/site/assets/cache/FileCompiler/site/modules/TracyDebugger/panels/RequestInfoPanel.php:181
Stack trace:
#0 /var/www/tgp/site/assets/cache/FileCompiler/site/modules/TracyDebugger/tracy-master/src/Tracy/Bar.php(159): RequestInfoPanel->getPanel()
...

Lastly, I cannot scroll the results pane horizontally. There is no scroll bar.

I have uninstalled the rss module, shutdown pw, and restarted... the behavior is consistent. So I am not sure whether this was present before I installed the rss module.

I am not sure if this is related, but on another localhost development site (never had rss module installed), I upgraded Tracy from .23 to .25 and got this error:

Failed to init module: TracyDebugger - Tracy\Debugger::dispatch() called after some output has been sent. Output started at /.../wire/core/FileCompiler.php:980

And the behavior is identical as seen with the other localhost site.

 

Edit: Additional Info...

I am not able to select any text from within the results pane. It behaves as if some selection is already in progress. When attempting to make a selection, either by mouse or keyboard, the selection starts at the very beginning of the results pane content and selects wherever the mouse or keyboard control was initiated. I have seen something like this before quite a while back. If I remember correctly it was a JS issue. I do not remember how it was resolved.

Hey @rick - sorry you've hard a bad run with Tracy here.

1) I believe the issue with MarkupRSSLoad to be a bug in that module. Replace this line:

https://github.com/ryancramerdesign/MarkupLoadRSS/blob/16e735b9ccc015eb36814689f862c007bff935a9/MarkupLoadRSS.module#L207

with:

    protected $items = array();

and this function:

https://github.com/ryancramerdesign/MarkupLoadRSS/blob/16e735b9ccc015eb36814689f862c007bff935a9/MarkupLoadRSS.module#L428-L430

with:

    public function getIterator() {
        return new ArrayObject($this->items);
    }

If that works and you find the module still works as expected, perhaps you could post an issue for Ryan on that module's github page.

 

2) As for the snippet name field in the Console panel - that is fixed in the latest version just committed.

3) I am getting a horizontal scrollbar in the Console panel here. Maybe there is some specific I am not doing to reproduce - can you provide more details?

image.thumb.png.99a1ba0868adcd1370e9067f1afbce21.png

 

4) I have seen the "Failed to init module: TracyDebugger - Tracy\Debugger::dispatch()" error a few times - it can happen when some error is output to the browser before Tracy is called. I am keeping my eye on this to see if it's something that can be fixed, but not sure it can. Let me know if you continue to see it on a regular basis and if something specific triggers it.

 

5) I can select text from the results pane, but maybe I just fixed that at the same time I fixed the snippet name focus issue. Let me know if you still have problems with this.

Hi @adrian,

I haven't had a bad run with Tracy at all. On the contrary, I nominate Tracy for module of the year. And you have done an excellent job of maintaining this indispensable tool.

I've made the changes to the rss module. I don't see anything crop up yet. Thanks for those.

Upgraded to Tracy.26 on both local installs and all is functioning well.

I appreciate your time and help!

A couple of tweaks today.

1) The "Template Info" section in Request Info panel now properly shows the data for the template being edited when you are editing the settings for a template in the admin.

2) The User Switcher now has an option to limit the list of available users by restricted roles. I had a site where I was using the Users system to store details for frontend members so the list was ridiculously long. Now I can exclude that member role to keep the list concise and easy to use.

Most of the time you can debug modules just fine - it all depends on the load order of things. I have asked Ryan via PM if he'd consider a special hook so that Tracy can be loaded earlier so that it's always available for all modules.

Perhaps we need a Github feature request for this?

Maybe it should come from someone other than me?

@adrian Here you are. Please take a look. I am not sure I put it well enough.

 

Thanks for that - I have commented on your request and also provided a very simple hack this get it working right now by including the tracy core file in the index.php at the root of your site. It seems to work brilliantly - great for debugging PW core files even.

Would be great if others could add their +1 to this please!

Is there an easy way to enable/disable Tracy debugger via API? As I am still on my way to create test with PHPUnit it would be awesome if there's an easy way (ideally via config.php) to disable tracy if it's called from the phpunit testing scripts.

Hi @adrian,

I'm seeing an issue in the Console panel where the indentation (tabs) of saved snippets gets lost when the page is reloaded. In the screen capture below I save the snippet with the correct indentation and I can load that snippet again okay until I reload the page. After that the snippet doesn't load with the correct indentation.

      LogMaintenance
      A simple ProcessWire module to give some maintenance control over log files. I found myself often having lots of log files for different things that can grow more or less quickly to a size where they can be difficult to maintain. The built in Logger of PW does a good job of giving you the possibility to delete or prune logs. But it has to be done manually and sometimes a log grows into millions of lines, which makes it often impossible to even prune it as it's too large.
      LogMaintenance uses LazyCron to run the maintenance task and there's several settings you can setup on a global or per log basis.
      Archive: will create zip files for each log file in logs/archive/ folder and add the log each time the maintenance is run to a subfolder containing the datetime.
      Lines: keeps logs to a certain number of lines 
      Days: keeps the log to a certain number of days
      Bytes: keeps the log to a certain amount of bytes
      Each setting is checked from top down, the first setting to contain something is used. So if you check the "Archive" option, all other settings are ignored and logs are archived everytime the LazyCron is executed. If you want to keep your logs to a certain amount of bytes just leave all other settings to 0 or blank.
      Per Log Settings
      There's a textarea that you can use to setup a config for a specific log file one per line. All the logs you define here ignore the global settings above. The syntax for the settings is:
      logname:[archive]:[lines]:[days]:[bytes] 
      errors:1:0:0:0 // would archive the errors log messages:0:10000:0:0 // will prune the errors log to 10000 lines  
      The module can be found on github for you to check out. It's still fresh and I'm currently testing.

      Fieldtype Page IDs is a third party Fieldtype that, simply put, stores Page references as integers (Page IDs).
      This fieldtype was built as a quick and dirty workaround for Page Reference fields' inability handle self-references due to circular reference issues. A project I've been working on for a while now includes a combination of RepeaterMatrix content blocks and tagging/categorization system that would've resulted in a lot of duplicate pages (and plenty of unnecessary manual work for content editors) had I used built-in Page Reference fields, and thus a new Fieldtype felt like the most sensible approach.
      Fieldtype Page IDs was designed to be loosely compatible with Page References in order to make conversions between the two feasible, but it is quite limited feature wise:
      largely due to the fact that stored values are actually just integers with no connection to Pages whatsoever some advanced selectors and related features are not supported, and page values can't be directly accessed configuration settings are limited to the bare essentials (selector string and Inputfield class) only a handful of Inputfields (AsmSelect, Checkboxes, Text) are (currently) supported Anyway, in case you need to store Page IDs (and Page IDs only) and are happy with the limitations mentioned above, feel free to give this Fieldtype a try. It has been working fine for me in one particular project, but hasn't been tested that much, so please tread carefully – and let me know if you run into any issues.

      This is a lightweight alternative to other newsletter & newsletter-subscription modules.
      You can find the Module in the Modules directory and on Github
      It can subscribe, update, unsubscribe & delete a user in a list in Mailchimp with MailChimp API 3.0. It does not provide any forms or validation, so you can feel free to use your own. To protect your users, it does not save any user data in logs or sends them to an admin.
      This module fits your needs if you...
      ...use Mailchimp as your newsletter / email-automation tool ...want to let users subscribe to your newsletter on your website ...want to use your own form, validation and messages (with or without the wire forms) ...don't want any personal user data saved in any way in your ProcessWire environment (cf. EU data regulation terms) ...like to subscribe, update, unsubscribe or delete users to/from different lists ...like the Mailchimp UI for creating / sending / reviewing email campaigns *I have only tested it with PHP 7.x so far, so use on owners risk
      EDIT:
      I've updated the module to 0.0.4. I removed the instructions from this forum, so I don't have to maintain it on multiple places. Just checkout the readme on github 🙂
      If you have questions or like to contribute, just post a reply or create an issue or pr on github.

      WHY?
      This module was built to fill the gap between simple $pages->find() operations and complex SQL queries.
      The problem with $pages->find() is that it loads all pages into memory and that can be a problem when querying multiple thousands of pages. Even $pages->findMany() loads all pages into memory and therefore is a lot slower than regular SQL.
      The problem with SQL on the other hand is, that the queries are quite complex to build. All fields are separate tables, some repeatable fields use multiple rows for their content that belong to only one single page, you always need to check for the page status (which is not necessary on regular find() operations and therefore nobody is used to that).
      In short: It is far too much work to efficiently and easily get an array of data based on PW pages and fields and I need that a lot for my RockGrid module to build all kinds of tabular data.

      Hej,
      A module which helps including Photoswipe and brings some modules for rendering gallery markup. Feedback highly appreciated
      (Also pull requests are appreciated 😉 - have a new Job now and don't work a lot with ProcessWire anymore, yet, feel free to contact me here or on GitHub, Im'm still "online"!)

      Modules directory: http://modules.processwire.com/modules/markup-processwire-photoswipe
      .zip download: https://github.com/blynx/MarkupProcesswirePhotoswipe/archive/master.zip
      You can add a photoswipe enabled thumbnail gallery / lightbox to your site like this. Just pass an image field to the renderGallery method:
      <?php $pwpswp = $modules->get('Pwpswp'); echo $pwpswp->renderGallery($page->nicePictures); Options are provided like so:
      <?php $galleryOptions = [ 'imageResizerOptions' => [ 'size' => '500x500' 'quality' => 70, 'upscaling' => false, 'cropping' => false ], 'loresResizerOptions' => [ 'size' => '500x500' 'quality' => 20, 'upscaling' => false, 'cropping' => false ], 'pswpOptions' => (object) [ 'shareEl' => false, 'indexIndicatorSep' => ' von ', 'closeOnScroll' => false ] ]; echo $pswp->renderGallery($page->images, $galleryOptions); More info about all that is in the readme: https://github.com/blynx/MarkupProcesswirePhotoswipe
      What do you think? Any ideas, bugs, critique, requests?
      cheers
      Steffen
