Tracy Debugger

Recommended Posts

Hey @bernhard - sorry for the recent silence. I am back in the office this week, but triaging work stuff first. Will try to take a good look at your other suggestions as soon as I can.

Regarding disabling Tracy on certain pages, that is what the "No debug bar in selected templates" setting is for. It seems to work fine here - is it not working for you?

That said, I can also see having a tracy=0 get variable as a useful addition for sure. I'll add that soon. 

Regarding the performance issue - could you narrow down which panel is the cause? I am constantly on the lookout for ways to improve performance, so it would be helpful if I could reproduce to see if something can be improved.

Actually thinking about this a little more - maybe the disabler should be turned into a panel with more options:

1) Disable Tracy all pages

2) Disable Tracy this page

And have Once and Sticky buttons to determine how long it's disabled for.

How does this sound compared to the get variable approach?

Of course this sounds better, but I'd also be happy with the get variable. Disable tracy on some templates does not work in my case because I'm developing process modules. So maybe the "disable tracy for selected templates" option could also be moved to this panel and away from the module settings (they are getting more and more complex 🙂 ).

So it totally depends on you and your spare time and if you think you'd also benefit from such a feature. Again: In my case the get var would be sufficient and I guess this would be a lot easier to implement.

Thanks and welcome back 😉

Hey @bernhard - regarding your fd() idea - is there a major difference between it and using l() which already dumps to Tracy log files?

Hi, in a new PW install after install the Tracy module and enable the "Development" mode I get strange responses from the site:

- On the frontend after clicking on a link the site stays processing and after a while gives a 404 page
- On the admin the site stays processing for a while and is slow.

I need to select the "Production" mode for the site to able to work. This is strange, the module never had this behaviour.

The installation is using:

- Processwire 3.0.98
- Tracy Debugger v4.10.22

Right now I do not know if there a module conflict or configuration that is making this behaviour.

Thank you

Hi @vmo - sorry I don't have any idea why you'd be getting a 404. Can you try unchecking all panels via the Panel Selector and see if that helps. Also, do older versions of Tracy work any better?

Is this a local or server install? What OS are you running? Apache or Nginx?

Could you try another install on the same server?

Could you try the Module Disabler panel to disable all other modules to see if there is a conflict?

Hi, @adrian - the installation is on a cpanel with Apache. The installation is a basic one with a few fields and templates (with no page) and with no modifications done to the original template files.
I copied the installation with the issue to another sub-domain and did the following actions:

- Disabled all extra site modules
- Removed all the custom templates and fields
- Only enabled the Tracy module in DEVELOPMENT mode (with no errors and 404 pages)
- With the Tracy in DEVELOPMENT mode: I reenabled all the others extra site modules one by one and tested for any errors, delays or 404 pages
- After reenabled all the modules no errors, delays or 404 pages were detected.
- Recreated the custom templates
- Recreated the custom fields

After this actions there wasn't datect any issue, but... after added a repeater field to the "home" template the same issue appeared
and started again to receive 404 pages and delayed page processing on the admin.

I did the following steps to try understand if there was any issue on the repeater field:

On the "home" template:
- Removed the repeater field from the "home" template
- After field was removed, No 404 errors were detected navigating the site
- Added again the repeater field to the "home" template and the same issue started
- Removed the field

On the "basic-page" template:
- Added the field to the "basic-page" template
- After added the repeater field to the "basic-page" template, no 404 errors were detected navigating in the site


Any ideia?
I can make a zip of the installation and send it to you, if it helps.

Hi @vmo - thanks for the hard work narrowing it down to repeaters on the homepage. I have no idea why though at this point. I think the one thing you missed in your debugging was unchecking all the debugbar panels. It would be helpful to know if that helps. If it does, try to narrow it down it a particular panel - most likely the RequestInfo panel. If that doesn't help, then sure send me the zip - I might not have time to look for a little while though.

Hi @adrian - After disabled the "RequestInfo panel" on the frontend panels stop receiving the 404 errors

and after disabled the "RequestInfo panel" on the backend panels the admin navigation and save is normal, does not delay.

Any next steps?

Thank you

I guess it's a matter of figuring out what part of that panel is causing the problem. It will most likely be the "Field List & Values" section. So you could try disabling that section only in the module config settings. If everything is still fine with the panel enabled, but that section disabled, then we need to figure out what bit of code in that section is causing the problem. Here's the code for that section: https://github.com/adrianbj/TracyDebugger/blob/2689b8ccc57bd5776a21cf6413a400c68d71a555/panels/RequestInfoPanel.php#L450-L473

In particular I would recommend looking through the getFieldArray() method that it calls. 

If you feel up to investigating the cause, that would be greatly appreciated. Otherwise, I will need to get some more details about that repeater field, because I have many sites with lots of repeater fields and haven't noticed a problem, so would need to be able to reproduce to debug.

Thanks for your help so far.

Hi @adrian - thank you for the hints to research the issue.

I just disabled the "Fields Object" on the Request Info Panel > Panel sections and the issue of the 404 does not appear.

I will take time to debug it but right now I need to put everything working for tomorrow and I will give feedback asap.

Thank you, all the best

Good to know - I haven't enabled that section in my RequestInfo panel in forever - I guess that's why I am not seeing the issue with repeater fields.

Thanks for narrowing it down.

Hi @adrian,

I'm still experiencing the issue below in the latest Tracy:

I can fix it with the CSS I mentioned earlier...

...but it would be handy to have that as an option built into the module so no custom CSS is needed. Thanks!

Hey @Robin S - I have been experiencing this again too. I though it was solved in some Tracy core updates, but apparently not 🙂

I tend to agree with you that there really isn't a need to move the bar, so I think a fixed option is probably a good idea, so I have added it in the latest version - the option is called: "Fixed Position". You might need a hard reload after changing this to see the effects.

This version also includes some more MySQL info in the Diagnostics panel. It's all about the current number of connections etc:

Hi! I always used Tracy Debugger. Now on a fresh installation, based on the Multilanguage version, i installed the Tracy Debugger module, but it doesn't show on the frontend! Idea? All the options seems right...

HI @pandaman - I really don't have any idea why it wouldn't be showing up. I use it on Multilanguage installs regularly. Does it show on the backend, or not at all?

Are you on a local dev setup? If not, make sure that Force Superuser into Development mode is checked, or force the Output Mode to Development.

Are there any JS errors in the browser dev console?

Hi @adrian

A feature request for your consideration: please could you apply the lovely code editor to the custom PHP textarea in the module settings? Would make editing custom PHP much easier.

Many thanks for your consideration!

Hi Steve,

Thanks for the suggestion. I have added it to the just released version. Please let me know if you have any issues with it.

PS - I am curious what you are using this panel for - I haven't had much feedback on it thus far.

@adrian Thank you. I was putting together a version-gathering script to collect the data to paste, as Markdown, into GitHub issues - then guess what I found elsewhere in TD 🤔

@adrian Thanks for the update - just tried it - but the value of the field no longer seems to save. Whatever I enter into the custom PHP code editor is lost on submit of the module settings.

Glad you found the "Version's List" functionality - pretty handy isn't it 🙂 Let me know if you think of any other info that should be added to it.

Sorry about the code saving bug - hope you didn't lose too much! It is fixed in the latest commit.

@adrian Thanks, that's fixed it, and nothing lost.

While you have this feature in your working memory, another request: could you have the config scroll to the custom PHP field if it were changed on the last save? That would allow a smoother flow of iterations using the field, and shouldn't interfere with anyone else's use of the config area. That would be the icing on the cake, but I'm totally happy with the cake the way it is at the moment 🙂

---

With regard to the Version List functionality, if anything, I think a "lite" version for initial reporting of just the PW, PHP, Webserver & MySQL versions as a markdown table would be useful. One thing that's struck me reading through the issues is that clarity matters. I really like the comprehensive data you've made available with the existing feature - but I completely missed the data, tucked away at the bottom of a couple of issues. It was only when I found the feature in Tracy that I had a lightbulb moment and realised that's where those three lines in the issue reports came from. (I like to follow the KISBIS rule where possible: Keep It Simple, Because I'm Stupid)

Check out the latest version - I think it works pretty nicely!

Happy to implement, but not sure the best interface - are you thinking about maybe splitting the the button into two: 

1) Copy Simple for Github

2) Copy Detailed for Github


Or do you have other ideas?

@adrian Fantastic! Thank-you, that works great.

Regarding the "Lite" reporting button idea; I'd gather a few more opinions on this before doing anything.

For example, another alternative is to just keep the existing button but make the basics a non-collapsed table with all the additional details in the collapsed sections following it. That would make the basics stand out pretty well in the issue reports.

      A community member raised a question and I thought a new sanitizer method for the purpose would be useful, hence...
      Sanitizer Transliterate
      Adds a transliterate method to $sanitizer that performs character replacements as defined in the module config. The default character replacements are based on the defaults from InputfieldPageName, but with uppercase characters included too.
      Usage
      Install the Sanitizer Transliterate module.
      Customise the character replacements in the module config as needed.
      Use the sanitizer on strings like so:
      $transliterated_string = $sanitizer->transliterate($string);

      Hello,
      this module can publish content of a Processwire page on a Facebook page, triggered by saving the Processwire page.
      To set it up, configure the module with a Facebook app ID, secret and a Page ID. Following is additional configuration on Facebook for developers:
      Minimum Required Facebook App configuration:
      on Settings -> Basics, provide the App Domains, provide the Site URL, on Settings -> Advanced, set the API version to 2.10, add Product: Facebook Login, on Facebook Login -> Settings, set Client OAuth Login: Yes, set Web OAuth Login: Yes, set Enforce HTTPS: Yes, add "http://www.example.com/processwire/page/" to field Valid OAuth Redirect URIs. This module is configurable as follows:
      Templates: posts can take place only for pages with the defined templates. On/Off switch: specify a checkbox field that will not allow the post if checked. Specify a message and/or an image for the post.
      Usage
      edit the desired PW page and save; it will post right after the initial Facebook log in and permission granting. After that, an access token is kept.
       
      Download
      PW module directory: http://modules.processwire.com/modules/auto-fb-post/ Github: https://github.com/kastrind/AutoFbPost   Note: Facebook SDK for PHP is utilized.

      I created a little helper module to trigger a CI pipeline when your website has been changed. It's quite simple and works like this: As soon as you save a page the module sets a Boolean via a pages save after hook. Once a day via LazyCron the module checks if the Boolean is set and sends a POST Request to a configurable Webhook URL.
      Some ideas to extend this:
      make request type configurable (GET, POST) make the module trigger at a specified time (probably only possible with a server cronjob) trigger manually Anything else? If there's interest, I might put in some more functionality. Let me know what you're interested in. Until then, maybe it is useful for a couple of people 🙂

      I created this module a while ago and never got around to publicising it, but it has been outed in the latest PW Weekly so here goes the support thread...
      Unique Image Variations
      Ensures that all ImageSizer options and focus settings affect image variation filenames.

      Background
      When using methods that produce image variations such as Pageimage::size(), ProcessWire includes some of the ImageSizer settings (height, width, cropping location, etc) in the variation filename. This is useful so that if you change these settings in your size() call a new variation is generated and you see this variation on the front-end.
      However, ProcessWire does not include several of the other ImageSizer settings in the variation filename:
      upscaling cropping, when set to false or a blank string interlace sharpening quality hidpi quality focus (whether any saved focus area for an image should affect cropping) focus data (the top/left/zoom data for the focus area) This means that if you change any of these settings, either in $config->imageSizerOptions or in an $options array passed to a method like size(), and you already have variations at the requested size/crop, then ProcessWire will not create new variations and will continue to serve the old variations. In other words you won't see the effect of your changed ImageSizer options on the front-end until you delete the old variations.
      Features
      The Unique Image Variations module ensures that any changes to ImageSizer options and any changes to the focus area made in Page Edit are reflected in the variation filename, so new variations will always be generated and displayed on the front-end.
      Installation
      Install the Unique Image Variations module.
      In the module config, set the ImageSizer options that you want to include in image variation filenames.
      Warnings
      Installing the module (and keeping one or more of the options selected in the module config) will cause all existing image variations to be regenerated the next time they are requested. If you have an existing website with a large number of images you may not want the performance impact of that. The module is perhaps best suited to new sites where image variations have not yet been generated.
      Similarly, if you change the module config settings on an existing site then all image variations will be regenerated the next time they are requested.
      If you think you might want to change an ImageSizer option in the future (I'm thinking here primarily of options such as interlace that are typically set in $config->imageSizerOptions) and would not want that change to cause existing image variations to be regenerated then best to not include that option in the module config after you first install the module.

      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.
      ProcessWire-Module: http://modules.processwire.com/modules/page-access-releasetime/
      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!
