Ticket: Bloqs crash if the template is to long and you have an if-statement outside of the field

Status Resolved
Add-on / Version Bloqs 3.3.1
Severity
EE Version 3.5.14

Description:
If you use :total_blocks variable in an if-statement outside of the field and the template size is too big the template crashes.

Detailed steps to reproduce the issue:
1.Create a bloq element with a text input inside.
2.Create an entry with bloq elements to test the issue.
3.Create an ee template with a lot of lorem ipsum text and one bloq element. It does not matter where the bloq-code is inserted in the template. To rebuild the template, check the code snippet.
4.Call the template in the browser.

<!DOCTYPE html>
<html>
<head>
<title>Website Title</title>
</head>
<body>
{exp:channel:entries channel="your_channel_name"}

{if "{your_fieldname:total_blocks}" > "1"}TRUE{/if}

{your_fieldname}
    {your_blocktype_shortname}
        {your_atom_name}
    {/your_blocktype_shortname}
{/your_fieldname}

[here insert your lorem ipsum text (+- 400 lines)]

{/exp:channel:entries}
</body>
</html>

This certainly seems odd. You’re saying it crashes… do you get an error message? Did you try :total_rows? What about trying the unquoted version, e.g. {if {your_fieldname:total_blocks} > 1}

Also, what is 400 “lines” of lorem ipsum. Lines aren’t really a thing on the web due to viewport width. Can you share the exact text you were using when experiencing the issue so I can use it to replicate?

Thanks for your response. No there is no error message and there is no difference between the unquoted and the other version. If I use :total_rows I have still the same bug. Sorry I can’t copy my whole code inside because the lorem ipsum text is 107596 characters long but you can create the text yourself.

<!DOCTYPE html>
<html>
<head>
<title>Website Title</title>
</head>
<body>
{exp:channel:entries channel="your_channel_name"}

{if "{your_fieldname:total_blocks}" > "1"}TRUE{/if}

{your_fieldname}
    {your_blocktype_shortname}
        {your_atom_name}
    {/your_blocktype_shortname}
{/your_fieldname}

[here insert your lorem ipsum text (107596 characters)]

{/exp:channel:entries}
</body>
</html>

Here is my output from my browser:

{your_fieldname}{your_blocktype_shortname} {your_atom_name} {/your_blocktype_shortname} {/your_fieldname} Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

Its going to be a day or two before I can replicate this. What other add-ons do you have installed? Did you try to replicate this in a clean EE environment with no other add-ons besides Bloqs?

This is without a doubt the most puzzling bug I’ve had reported.

I’m able to replicate this locally, and based on what I’m seeing I feel like this is a deeper issue with EE’s template parsing because the Bloqs code that is supposed to parse the tag isn’t even called, so something is failing before Bloqs gets a chance to do anything with it. I’m going to report this to EllisLab and see what they say.

So you can follow https://expressionengine.com/support/bugs/23434/fieldtype-replace-tags-not-parsed-when-very-large-blocks-of-text-are-present

We use these other add-ons: - ansel - channel-images - Low Seg2Cat - NavEE - stash - tag - Treasury

We found a way to temporarily fix the bug: You can create an embed and then insert your new embed into the template. With this trick the template can be parsed.

If you increase your pcre.backtrack_limit it should fix the issue. Seems a regular expression is failing inside of EE somewhere before Bloqs gets to parse the field contents. Either edit your php.ini, or add this to your .htaccess file:

php_value pcre.backtrack_limit 10000000

Thanks for your help, with your idea we were able to fix the error. We increased the pcre.backtrack_limit and now we have no problems with big templates and bloqs.
