Recursion due PageArray request.

[M-O-Z-G]

Hello, I'm testing PW3 now, and found some buggy behavior with get request to dump panel or logger. For example:

$page->get("FIELD_PAGE_ARRAY_NAME");

With Tracy Debugger 1.8* such requests runs to 500 Server error. But after upgrade to 1.9.0 the request gets a recursion from array item _wire protected => ProcessWire\ProcessWire.

Works well in PW2.7.*

HI @M-O-Z-G - thanks for the report. Did you by any chance change the Maximum Nesting Depth setting of 3? That setting wasn't being used by fireLog calls until recently. That is the only change I can think of that might be causing this.

It is the ERR_RESPONSE_HEADERS_TOO_BIG that you were getting? I am still getting that with PW 3.x and TD 1.9.x

I am running a newer version of the Tracy core though, so maybe that's it.

Can you please give me more details on the field you are dumping?

Hello @adrianbj,

Thanks for attention. I had updated to 1.9.1 - same result. I have attached dump below.

What is the exact code you typed in the console to get that response?

Have you changed the Max Nesting Depth setting - what is it set to?

What is the exact code you typed in the console to get that response?

dump($page->get("PAGE_FIELD_NAME"));

Have you changed the Max Nesting Depth setting - what is it set to?

Five in this case. Why do you ask about? PW2.7 doesn't have a recursion for same request even when MaxDepth is ten. Or the recursion is normal for PW3? I just assumed that issue with Tracy, don't sure may be it's PW3 behavior.

[adrianbj]

Ok, I have just been comparing the results of a page field dump between PW 2 and 3 and the difference is that PW 3 adds this section:

I haven't changed anything else. Even if I revert to an older version of Tracy, eg 1.7.9 the same problem exists - very slow loading of the page, the extra content in the dump and the recursion error. It seems like it's PW 3 specific at the moment - now just to figure out if it can be fixed in Tracy, or if the change needs to be in PW. I'll keep investigating.

[adrianbj]

Hi @M-O-Z-G - I am looking at this again and honestly don't know how you are ending up with that dump result. Could you send me some more details of the field that is referenced by "PAGE_FIELD_NAME". Any chance you could also send me the html from the dump.

[M-O-Z-G]

Hello @adrianbj,

In fact, I really don't know how exactly to check it. I opened front page of default multilang site template, and Recursion appears right in the Page Object Stack on the Info Panel. And so on any page.

I had also tried disable extra modules.

Tested on 3.0.21, 3.0.25

Thanks, but if that is the only issue, then I don't think there is anything actually wrong here. Here is a comment from Ryan:

the _wire reference present in every Wire derived object points to the current ProcessWire (class) instance. Because the ProcessWire class extends Wire, that means it also has a _wire property, and that property points to itself. That's not inherently a problem, and it's necessary for access to API variables by all Wire-derived objects. This is one of the means by which we support multiple instances of PW. There is no recursion unless some code tries to follow the protected _wire property of the protected _wire variable.

Tracy is actually recognizing this and returning the { RECURSION } text (https://github.com/nette/tracy/blob/b4ecf4371a5a2e406cea99061b01f33fc7393bb5/src/Tracy/Dumper.php#L208) rather than actually trying to render them at all.

Does that sound ok to you?

[adrianbj]

@M-O-Z-G - any final thoughts on this? I really don't think there is anything actually wrong that needs fixing. Both Tracy and ChromeLogger (https://github.com/ccampbell/chromephp/blob/master/ChromePhp.php#L291) deal with objects referencing themselves by marking them as recursion.

Is it ok if I close this?

[M-O-Z-G]

Hello @adrianbj, sorry for delay. Understand, but in fact I not seen problem in recursion itself. Problem was with freezing of browser with a lot of recursion. I had updated PW and TracyDebugger for Latest versions, and don't see such a critical behavior, even with big nesting. May be something changing in PW. So, you can close this issue, I will reopen if something critical will appear in future. Thank you for your hard work, you are one of thorough developers that I know!

[adrianbj]

Glad it seems to be working better.

Thanks for the kind words!
