Not all image edits are applied to all subsizes

[mitogh]

When editing an image using the admin editor, not all edits are applied correctly to all image subsizes. Specifically, the problem occurs when an edit results in a smaller size than the defined image size. Given the following image subsizes, and the attached image.

=> array(6) {
  ["thumbnail"]=>
  array(3) {
    ["width"]=>
    int(150)
    ["height"]=>
    int(150)
    ["crop"]=>
    bool(true)
  }
  ["medium"]=>
  array(3) {
    ["width"]=>
    int(300)
    ["height"]=>
    int(300)
    ["crop"]=>
    bool(false)
  }
  ["medium_large"]=>
  array(3) {
    ["width"]=>
    int(768)
    ["height"]=>
    int(0)
    ["crop"]=>
    bool(false)
  }
  ["large"]=>
  array(3) {
    ["width"]=>
    int(1024)
    ["height"]=>
    int(1024)
    ["crop"]=>
    bool(false)
  }
  ["1536x1536"]=>
  array(3) {
    ["width"]=>
    int(1536)
    ["height"]=>
    int(1536)
    ["crop"]=>
    bool(false)
  }
  ["2048x2048"]=>
  array(3) {
    ["width"]=>
    int(2048)
    ["height"]=>
    int(2048)
    ["crop"]=>
    bool(false)
  }
}

The defined sizes above are the ones coming by default with the setting provided below.

Steps to replicate the problem:

1. Upload the image into your installation.
2. After the image is uploaded, click on edit to open the image editor or go to the image editor from within the media library.
3. Click on Edit image
4. Click on rotate image (either right or left) only once.
5. Make sure the changes are applied to all images by checking that the setting Apply changes to: All image sizes is set
6. Click on save

After the image is saved observe the changes were applied only to the following image sizes:

• thumbnail
• medium
• large
• full

The only size that was not updated as expected was:

• medium_large

Good catch @mitogh! Looks like some conditional checks for in image-edit.php aren't working as expected.

In my testing this happened when the i rotated to the vertical position. rotating again and saving my medium_large size was correctly edited. flipping images always seemed to work. cropping worked until i tried a vertical thin crop, then some sizes were saved and others not.

[mitogh]

Right, it seems like the issue happens for rotation specifically on images that do not have dimensions like a landscape or portrait image if is rotated the dimensions are different, flip works normally on my end due to the image dimensions are not modified from the original image.

Let me know in case you have any additional questions. @adamsilverstein, thanks for taking a look and replicating the steps for this issue.

If time allows I can try to find a patch for this one as well.

[SergeyBiryukov]

Hi there, welcome back to WordPress Trac! Thanks for the ticket.

Just noting that I was able to reproduce the issue with the steps described. I was also able to confirm comment:1.

[mitogh]

I've added a patch with a suggested fix. The suggested fix follows the same approach as WordPress follows when the image is uploaded for the first time, this approach is basically that when an uploaded image is smaller in dimensions than an image size the image size is not created for the image, which was the case for this image when the image Was rotated it was smaller in dimensions that the failed size creating an error and not saving the edit.

As described this approach would not save any image that was errored out by the editors, images would remain in the backup sizes and can be restored at any point in time, by rolling back an existing size.

The function wp_get_additional_image_sizes was replaced with wp_get_registered_image_subsizes in order to have a more accurate access to the defined image sizes by the user.

Cast of values to int was introduced as well in order to make sure settings (as strings) were converted to integers.

[costdev]

Per the discussion in the bug scrub, this still needs-testing, needs-unit-tests and a review to ensure no BC breaks are introduced. Moving to the 6.1 milestone.

[adamsilverstein]

I've added a patch with a suggested fix

@mitogh is the patch you uploaded complete?

[mitogh]

YEs @adamsilverstein the patch work is complete let me know if you have any additional questions.

[alaca]

The provided patch does not fix the issue with missing image, in this case for medium_large size.

As you already wrote, @mitogh, the new image will not be created when the image dimensions are smaller than the image size, e.g. this will happen when rotating the image to a vertical position.

However, I still found this patch useful as it adds a few small improvements.
Replacing wp_get_additional_image_sizes with the wp_get_registered_image_subsizes function returns a more accurate list of defined image sizes, and casting options settings to an integer is what was missing in the first place.

[joedolson]

Refresh patch with minor changes

[joedolson]

Refreshed patch also changes the variable name from $_wp_additional_image_sizes to $_wp_registered_image_sizes, so that the variable matches the data source. While the results of wp_additional_image_sizes and wp_registered_image_sizes should be very similar, it will make the code easier to follow for these to match.

@alaca In my tests, these changes do fix the missing file in the case you described: rotating a horizontal image to a vertical position produces all the expected image edits. Are you getting a different result?

[adamsilverstein]

@joedolson this ticket came up in the performance team bug scrub today. Is this still a candidate for 6.1 given that we are waiting for more testing/reviewer feedback? Or can we punt this to 6.2?

[joedolson]

I think we should still get this into 6.1. I can't identify the additional issue cited by @alaca, but I think that even if this patch is incomplete in some unidentified way, it does fix a significant image editing error. If there's a separate issue, that can be a new ticket.

[pushpak.pop]

The latest patch does fix issues with edits not applying to some sizes.

I did not encounter any specific issues with the testing I did.

This can go as is to fix the main issue and any related issues can be a new separate ticket

[joedolson]

Punting to 6.2. Still need some work to get the unit tests together for this fix; perhaps we'll get feedback about the potential missing fix.

[mukesh27]

@joedolson this ticket came up in the performance team bug scrub today. Are you working on unit tests?

[adeltahri]

I just tested it on WordPress trunk 6.2.0 with and without the latest patch, and it works. I didn't encounter any issues during my testing.

[adamsilverstein]

I just tested it on WordPress trunk 6.2.0 with and without the latest patch, and it works. I didn't encounter any issues during my testing.

I tested this with the latest patch applied and still see the issue. The medium_large rotated image is not created.

• note: use the original image attached to this ticket for testing. use the default wp theme with no plugins active.
• after uploading, check the uploads folder and see which image seizes were created.
• edit the image, rotate 90 degrees and save
• note the newly created rotated versions - there is one fewer version

the image is excluded because it violates the out of bounds check in image_resize_dimensions ​here. As far as I can tell the patches don't address this, so it needs more testing. Also, this definitely needs unit tests that validate the issue and the fix.

[flixos90]

@joedolson Is there a recent PR or patch for this ticket? I'm conscious that there haven't been any code updates for this ticket in the past few months and we're getting close to 6.2-RC phase.

Is this still reasonable to land at this time, or should we punt it? I acknowledge it is a bug, but it appears to be a rather complex one, and one that's not introduced by any recent WordPress core version, but has been around for a while.

On that note, I'm gonna remove the 5.9.1 version annotation here, as that field should be used for the version where this bug was introduced, not which version it was tested with. I'm not sure which version it was introduced in, but it has there been longer than 5.9.1.

[joedolson]

Yes, I think this should be punted to 6.3. It does seem to be a pretty fussy bug, and it's definitely not new.

I haven't done the archaeology to figure out where this comes from, but I agree that it's considerably older than 5.9.1.

[agnieszkaszuba]

I tried to test this but default image size medium_large doesn't exist in the latest WordPress version and theme.
I can confirm that the edit was applied to all the existing default sizes (thumbnail, medium, large, fullsize) though.

Moving 6.4 to keep focus on the higher priority issues in 6.3

[mukesh27]

This ticket was discussed during the Performance bug scrub.

This ticket is currently being actively worked on by @joedolson for the 6.4 release cycle. It was agreed to remove the performance focus.

Additional props to: @joemacgill @flixos90 @spacedmonkey

[oglekler]

Patch needs to be tested, it is possible that it will need refresh, but someone needs to try it to check.

[huzaifaalmesbah]

@oglekler I tried to test. its needs refresh.

[nicolefurlan]

@joedolson just checking on this one, are you able to refresh the patch?

[antpb]

With 6.4 RC1 fast approaching this should move to 6.5. Confirmed okay with @joedolson .
