Tracy Debugger

Recommended Posts

Hey @adrian, thanks for the update.

At the moment  Tracy doesnt check whether ready.php and finished.php exists or not, and gives this error.

Sorry about that - should be fixed in the latest version.

More improvements to the Captain Hook panel which I think now makes it the definitive source for browsing and understanding what each hook does. 

You have always been able to click the line number to open the file to the line of the method in your code editor (if you have things set up correctly), but this new version adds the following two new features:

1) Inline documentation for each hook - click method (last column) to expand/collapse the docs:

2) Direct link to PW API reference (from the Class::method link in the first column), eg clicking on "Pages::saved" will take you directly to this page:

Another small update for Captain Hook.

Now if you have Ryan's ProcessWire API Explorer module installed, the Class::method link will take you to the appropriate page of the API Explorer interface, rather than to the processwire.com API docs page.

This means it will work offline, and of course also means it will be updated to the version of PW running on your site.

Yep - another Captain Hook update. Often hookable methods for a class are derived from a parent class.

Take the "Roles" class for example. It lists add, delete, & save as the hookable methods that are available. But because it extends the "PagesType" class, its hookable methods are also available from the "Roles" class, eg: Roles::deleted.

To make these derived methods easier to find, I have added a new:

ClassName extends ParentClassName line to each file section. Both names are also linked directly to the API docs so you can find out more info there as well.

hi adrian,

just updated tracy from the version before the console ready.php include and now i got an error

Call to a member function addHookAfter() on null

because i add my hooks like this:

  // set all languages active automatically
  $wire->addHookAfter('Pages::added', function($event) {
    $page = $event->arguments(0);
    foreach ($this->wire->languages as $lang) $page->set("status$lang", 1);
    $page->save();
  });

as quickfix i added this on top of the file:

$wire = $this->wire;

i think it would be nice to have the wire variable available by default. what do you think?

hi adrian, me again :)

just wanted to try captain hook and got a memory error with the default 128M php setting:

Quote

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 72 bytes) in /var/www/vhosts/.../httpdocs/site/assets/cache/FileCompiler/site/modules/TracyDebugger/panels/CaptainHook/CaptainHookSearch.php on line 47

setting it to 256M helped but I'm not sure why this happend or if tracy should also work with 128M of memory and this is a bug?

Hi @bernhard - that $wire issue is interesting. I will take a look soon.

As far as the memory limit issue with Captain Hook - I reduced my memory down to 64MB and it still worked. I had to go to 32MB to get the error so I am wondering what file caused the error on your system. Could you please debug the path of $file in this function: https://github.com/adrianbj/TracyDebugger/blob/8b92a7d6aec5d9999a77f591496fe8b3ed32080b/panels/CaptainHook/CaptainHookSearch.php#L44

Hopefully that last one to be output should be the file that is causing the limit to be reached. That will at least give me an idea of what is going on. I could of course just set a higher memory limit for this panel, but would like to see what is causing it to fail first.

Thanks!

Hey @bernhard - I took another look at the $wire variable not being available in ready.php (and init.php / finished.php) and this has been fixed in the latest version. Please confirm it all works at your end please.

Small update to the ProcessWire Info panel which adds a new redirecting "Login" button. 

Obviously this is only relevant if you have checked the "Force Guest Users into Development Mode on Localhost" option in the config settings. I always do this because I like the Tracy debug bar enabled whether I am logged in or not when developing. 

The nice thing about this login button is that it redirects to the page you were on when you clicked it, so you can be viewing a page on the frontend of your site, click this button, enter your credentials and you will be automatically redirected back to the page you were viewing.

Showing the login button:

And if you are already logged in, then you'll get a logout button instead (which also returns you to the current page after logout):

The Captain Hook cache should be reset when you update any modules (including Tracy), or the PW core, so it should already be taken care of, but just in case, go to the database "caches" table and delete the "TracyCaptainHook" row.

Just an idea: could you please implement it in @Soma'Clear Cache Admin and create a pull request for it? You might also want to pull up your sleeves and try to persuade him to register it in the Modules Directory:-[

Or you might just want to integrate his module into Tracy? (At least its features.) ;)

I hope I'm not asking for too much. Thanks for all your great community service as always!!!

Soma's module already includes it - it finds all WireCache caches automatically - note "TracyCaptainHook" at the bottom.

I am tempted to incorporate the features from his module into Tracy - it seems like an appropriate feature to have and I do like having less modules to install/update. I'll have a think on it for a bit!

Anyone else have any strong feelings on this?

Cool, good to know, thanks! I have not yet tried TracyCaptainHook – to tell the truth – so I guess that is why I did not notice it.

Thanks. It might be useful to have it as a separate module but I do not think editors should use it, so probably it is a good fit for Tracy. Let's see what others say.

That would explain it - now to figure out how to fix it. Ideally it would be good if libraries included in PW modules were excluded from the Captain Hook search (since there obviously won't be any hookable methods in them), but not sure there is a foolproof way to do that. I think an easy fix (which should work in most cases) is to do an initial check for "___" in the file before scanning fully. This will only fail if a vendor library also uses the three underscore method prefix approach. I'll try this and see how we go.

It's actually a nice speed improvement for the panel (when not cached), so a good thing to do regardless.

Please try the latest version, remembering to clear the cache, and let me know how it goes for you.

Great, thanks for letting me know.

I just committed another update which fixes the issues you were having with the Captain Hook cache not automatically clearing when upgrading Tracy. It will now clear when you upgrade, install, or uninstall any modules, click the modules > refresh button, or change PW core versions.

Also, uninstalled (but not deleted) modules will no longer have their hooks shown.

Hi everyone,

For those of you running the core SessionHandlerDB module, I just committed an experimental fix for the problem of the "Redirect" bar not showing. The redirect bar can be very handy in debugging many things that may otherwise be lost when there is a redirect, so it's been a real shame for those who haven't had it all this time.

59bd49ff1d133_ScreenShot2017-09-16at8_57_07AM.png.0fded13a06e1c8e16251ea68267c44da.png

I discussed the approach of my fix with Ryan and long time ago (I was hoping he might include it in the core) and this was his response to me:

Quote

in experimenting with this stuff in the past, we came across servers that basically halted the PHP after a redirect or connection close header. I never experienced that behavior, but others did.

Basically what the fix does is when a $session->redirect is called, it now makes the header() call before closing down ProcessPageView. The current PW core behavior is to close it down before the redirect.

I don't think it should be an issue for your sites to use this new version because it only makes this change if:

1) SessionHandlerDB is installed
2) The debug bar is enabled

#2 in particular means that regular users won't be impacted by this at all - only users with Tracy permission (typically just superusers).

However if you notice any problems at all, just add this line to your config.php file to disable it.

$config->disableTracySHDBRedirectFix = true;

And, of course let me know if you have problems so I can revisit my decision on incorporating this fix.

Hi @adrian,

Might be a silly question, but just wondering why the dump output doesn't appear in the same order that the dumps occur in. So if I do...

 2017-09-26_183741.png.4acb0f939c4be146152bc5961399a186.png

...how come the output order is reversed?

      Repeater Images
      Adds options to modify Repeater fields to make them convenient for "page-per-image" usage. Using a page-per-image approach allows for additional fields to be associated with each image, to record things such as photographer, date, license, links, etc.
      When Repeater Images is enabled for a Repeater field the module changes the appearance of the Repeater inputfield to be similar (but not identical) to an Images field. The collapsed view shows a thumbnail for each Repeater item, and items can be expanded for field editing.
      Screencast

      Installation
      Install the Repeater Images module.
      Setup
      Create an image field to use in the Repeater field. Recommended settings for the image field are "Maximum files allowed" set to 1 and "Formatted value" set to "Single item (null if empty)". Create a Repeater field. Add the image field to the Repeater. If you want additional fields in the Repeater create and add these also. Repeater Images configuration
      Tick the "Activate Repeater Images for this Repeater field" checkbox. In the "Image field within Repeater" dropdown select the single image field. You must save the Repeater field settings to see any newly added Image fields in the dropdown. Adjust the image thumbnail height if you want (unlike the core Images field there is no slider to change thumbnail height within Page Edit). Note: the depth option for Repeater fields is not compatible with the Repeater Images module.
      Image uploads feature
      There is a checkbox to activate image uploads. This feature allows users to quickly and easily add images to the Repeater Images field by uploading them to an adjacent "upload" field.
      To use this feature you must add the image field selected in the Repeater Images config to the template of the page containing the Repeater Images field - immediately above or below the Repeater Images field would be a good position.
      It's recommended to set the label for this field in template context to "Upload images" or similar, and set the visibility of the field to "Closed" so that it takes up less room when it's not being used. Note that when you drag images to a closed Images field it will automatically open. You don't need to worry about the "Maximum files allowed" setting because the Repeater Images module overrides this for the upload field.
      New Repeater items will be created from the images uploaded to the upload field when the page is saved. The user can add descriptions and tags to the images while they are still in the upload field and these will be retained in the Repeater items. Images are automatically deleted from the upload field when the page is saved.
      Tips
      The "Use accordion mode?" option in the Repeater field settings is useful for keeping the inputfield compact, with only one image item open for editing at a time. The "Repeater item labels" setting determines what is shown in the thumbnail overlay on hover. Example for an image field named "image": {image.basename} ({image.width}x{image.height})

      Hello There Guys.

      I am in the process of getting into making my first modules for PW and i had a question for you PHP and PW gurus in here.

      I was wondering how i could use an external library, lets say TwitterOAuth in my PW module.
      Link to library
      https://twitteroauth.com/

      Would the code below be correct or how would i go about this:
      <?PHP namespace ProcessWire; /* load the TwitterOAuth library from my Module folder */ require "twitteroauth/autoload.php"; use Abraham\TwitterOAuth\TwitterOAuth; class EyeTwitter extends WireData,TwitterOAuth implements Module { /* vars */ protected $twConnection; /* extend parent TwitterOAuth contructor $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $access_token, $access_token_secret); */ public function myTwitterConnection ($consumer_key, $consumer_secret, $access_token, $access_token_secret) { /* save the connection for use later */ $this->twConnection = TwitterOAuth::__construct($consumer_key, $consumer_secret, $access_token, $access_token_secret); } } ?> Am i on the right trail here or i am barking up the wrong tree?
      I don´t need a complete solution, i just wonder if i am including the external library the right way.
      If not, then give me a few hint´s and i will figure it out.

      Thanks a bunch.

      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 (has been tested up to v3.3), 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.

      FieldtypeRuntimeMarkup and InputfieldRuntimeMarkup
       
      Modules Directory: http://modules.processwire.com/modules/fieldtype-runtime-markup/
      GitHub: https://github.com/kongondo/FieldtypeRuntimeMarkup
      As of 11 May 2019 ProcessWire versions earlier than 3.x are not supported
      This module allows for custom markup to be dynamically (PHP) generated and output within a page's edit screen (in Admin).
       
      The value for the fieldtype is generated at runtime. No data is saved in the database. The accompanying InputfieldRuntimeMarkup is only used to render/display the markup in the page edit screen.
       
      The field's value is accessible from the ProcessWire API in the frontend like any other field, i.e. it has access to $page and $pages.
       
      The module was commissioned/sponsored by @Valan. Although there's certainly other ways to achieve what this module does, it offers a dynamic and flexible alternative to generating your own markup in a page's edit screen whilst also allowing access to that markup in the frontend. Thanks Valan!
       
      Warning/Consideration
      Although access to ProcessWire's Fields' admin pages is only available to Superusers, this Fieldtype will evaluate and run the custom PHP Code entered and saved in the field's settings (Details tab). Utmost care should therefore be taken in making sure your code does not perform any CRUD operations!! (unless of course that's intentional) The value for this fieldtype is generated at runtime and thus no data is stored in the database. This means that you cannot directly query a RuntimeMarkup field from $pages->find(). Usage and API
       
      Backend
      Enter your custom PHP snippet in the Details tab of your field (it is RECOMMENDED though that you use wireRenderFile() instead. See example below). Your code can be as simple or as complicated as you want as long as in the end you return a value that is not an array or an object or anything other than a string/integer.
       
      FieldtypeRuntimeMarkup has access to $page (the current page being edited/viewed) and $pages. 
       
      A very simple example.
      return 'Hello'; Simple example.
      return $page->title; Simple example with markup.
      return '<h2>' . $page->title . '</h2>'; Another simple example with markup.
      $out = '<h1>hello '; $out .= $page->title; $out .= '</h1>'; return $out; A more advanced example.
      $p = $pages->get('/about-us/')->child('sort=random'); return '<p>' . $p->title . '</p>'; An even more complex example.
      $str =''; if($page->name == 'about-us') { $p = $page->children->last(); $str = "<h2><a href='{$p->url}'>{$p->title}</a></h2>"; } else { $str = "<h2><a href='{$page->url}'>{$page->title}</a></h2>"; } return $str; Rather than type your code directly in the Details tab of the field, it is highly recommended that you placed all your code in an external file and call that file using the core wireRenderFile() method. Taking this approach means you will be able to edit your code in your favourite text editor. It also means you will be able to type more text without having to scroll. Editing the file is also easier than editing the field. To use this approach, simply do:
      return wireRenderFile('name-of-file');// file will be in /site/templates/ If using ProcessWire 3.x, you will need to use namespace as follows:
      return ProcessWire\wireRenderFile('name-of-file'); How to access the value of RuntimeMarkup in the frontend (our field is called 'runtime_markup')
       
      Access the field on the current page (just like any other field)
      echo $page->runtime_markup; Access the field on another page
      echo $pages->get('/about-us/')->runtime_markup; Screenshots
       
      Backend
