Topic on Extension talk:StructuredDiscussions

Hello, I am running a private enterprise SMW with Echo and Flow with VisualEditor and parsoid. The entire combination seems to work great except that for *some* users, using the mention feature results in the message "Internal Database Error" upon submitting the comment. However, the comment DID submit if the page is refreshed, and the mention link is intact, yet no notification is sent to the user mentioned. How can I debug this?

Product	Version
MediaWiki	1.28.2
PHP	5.6.32 (apache2handler)
MariaDB	5.5.56-MariaDB
ICU	50.1.2

Flow	1.1 (6ecdef3)2017-04-16T23:46:13
Echo	– (f55bdd9)2016-10-25T16:11:28
VisualEditor	0.1.0 (93528b7)2016-10-25T16:23:47
parsoid	/0.7.1+git

@Cindy.cicalese test

@Revansx

To help troubleshoot the issue, I have promoted a few users to the exact same list of groups and rights as I have as sysop to no avail. I was thinking that it might just be a permissions error for the "added rights" introduced with the Flow extension, but based on the test with the promoted user that doesn't seem to be the case.

this just in ... it turns out that I am getting the error.. hmm?

--> screenshot <--

how does one determine if the issue is with Flow or Echo or VisualEditor or Parsoid?

I have users complaining about a similar error, @Revansx (and, hey Echo/Flow, devs, shouldn't you promote users in the thread in the completion box for mentions?)

Let me see if it is coming from the same sort of db error.

Ok, my first error is a content warning. Somehow "https:" is becoming "http:" somewhere along the way, so this doesn't look like your error (yet).

Did you try running update.php? What does the debug log say?

(Somehow "https:" is becoming "http:" somewhere along the way) ... this could explain a lot of other quirky behavior I am experiencing.. yes, I have run the update script, however, I run it with the "--skip-external-dependencies" because of some reason I can't remember. It won't work without that.

I'll check the debug.. sec..

Can you try turning on the debug log for one request and reporting what errors it contains?

Here's the debug log when the error happens (I had to alter and delate some of the particulars

@MarkAHershberger someday I hope to be able to look at the debug logs and make some meaningful observations, ha ha :-)

I see 2 errors here:

• [error] [WgODrr21@lacG74H9ca8XQAAAAI] /mywiki/api.php ErrorException from line 295 of /var/www/html/mywiki/includes/changes/RecentChange.php: PHP Notice: Undefined index: rc_new
  • This is just a PHP notice, not really an error, but probably worh reporting it
• [fatal] [d89208cc] PHP Fatal Error: Cannot override final method EchoEventPresentationModel::getType()
  • This seems to be the real error here

Thank you for looking at it. Does that mean I should look in the PHP logs for more clues?

here are the corresponding PHP errors:

@MarkAHershberger, @Ciencia Al Poder .. this?

/extensions/Flow/includes/Notifications/MentionPresentationModel.php on line 65

That is probably what is causing the problem. It looks like your Flow extension is from a different, incompatible point in time of your Echo extension.

How did you get both of those extensions?

Ah! ("I see!" said the blind man :-) ) ... oh, I just installed them at different times from the download manager and manually imported them to my site, etc.. . Since I'm running MW 1.28.2 should I use composer to update them? If so, which versions would you recommend

So the download manager skips MW 1.28 on both Echo and Flow.. I think I have the 1.27 version of each loaded.. is there something specifically tricky about getting them to work in a 1.28 MW core?
