[4.x]: IntegrityException when saving entry at same time as automatic saving

[smcyr]

What happened?

Description

When I have an entry with a couple of simple fields. Sometimes, when I save rapidly at the same time as the automatic saving (which happens often for me when I save with ctrl+s), I get this error:

This also happens in Craft 3.7.x. I've just had this twice in the last 10 minutes when quick-saving while writing an article.

[adrienpicard]

Same as @darylknight, I just faced that exact error on a 3.7.40.1 install.

[FransvdWijst]

We encounter similar issues in Craft 3.7.42 and are able te reproduce it in a fresh install of Craft.

This error occurs in a very specific situation.

Needed to reproduce: Craft version: 3.7.42 Plugins: Vizy (1.0.13)

What we did: 1: Create a second website in /admin/settins/sites, so we have 2 websites. 2: Create a file volume, we need that to upload images. 2: Create a text field, file field, and a vizy field (with previously created text and file field (or any other)). 3: Create a new single and set as homepage. 4: Assign Vizy field and image field to this single (in this order: Vizy / Text / File ) 5: Try adding Content (in every field). -> wait when draft is saved 6: Save entry.

The error enclosed will occur,

What you can do to not show this error is one of the following:

• Disable vizy plugin
• Disable second website of the homepage single
• remove the file field from homepage (not from a vizy block, this can stay)
• set autosaveDrafts to false in config file

We're also seeing this issue. Craft version - 3.7.40

It only occurs with a specific entry type. All other entry types save without throwing this error.

The error thrown.

Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`klr_prod`.`changedfields`, CONSTRAINT `changedfields_elementId_fk` FOREIGN KEY (`elementId`) REFERENCES `elements` (`id`) ON DELETE CASCADE ON UPDATE CASCADE)
The SQL being executed was: INSERT INTO `changedfields` (`dateUpdated`, `propagated`, `userId`, `elementId`, `siteId`, `fieldId`) VALUES ('2022-05-19 17:56:21', 0, 1, 167141, 1, 78) ON DUPLICATE KEY UPDATE `dateUpdated`='2022-05-19 17:56:21', `propagated`=0, `userId`=1 in /home/forge/kahnlitwin.com/vendor/yiisoft/yii2/db/Schema.php:67

If I hit the back button and reload the entry edit screen I see the "Entry Saved" cp message and the data I've edited has been saved.

@JohnCBent that sounds more like #11083, which was fixed in 3.7.41.

[domstubbs]

I’m seeing the same errors when saving entries with 3.7.42.

SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (DB.craft_changedfields, CONSTRAINT craft_changedfields_elementId_fk FOREIGN KEY (elementId) REFERENCES craft_elements (id) ON DELETE CASCADE ON UPDATE CASCADE)

Thanks all! Just released Craft 3.7.43 and 4.0.3 with a fix for this.
