Unmount images while loading

[sospedra]

I'm loading few images per scene but they take a few seconds to load.
That means that in the meantime the user can navigate to another scene.
Causing the images to unmount before they finish loading.
Which triggers the following warning:
Task orphaned for request <NSMutableURLRequest: [[SOME_HEX_CODE]]> { URL: [[IMG_URL]] }

It's not crashing. I just want to know if relying the loading cancellation to React unmounting is ok? Having these warning all around is safe?

Note variables wrapped in [[]]

This is also an issue when using FlatList with a list of items that contains images. Because the View gets unloaded all the time when scrolling, you will get a lot of these warnings.

This will help: https://github.com/kfiroo/react-native-cached-image
It inserts View first, before image loading is complete.
I forked repository (https://github.com/iegik/react-native-cached-image) and try to reach following goals:

• Customizable image loader (Suggestion: passing a customised ActivityIndicator or SpinnerComponent kfiroo/react-native-cached-image#25) (Suggestion: Progressive image loading algorithm by Medium kfiroo/react-native-cached-image#55)
• Cache image request, save on device`s temporary folder
• Cache with expiration policy (Is there any way to set expiration policy for cache? kfiroo/react-native-cached-image#40)
• Support 304 Not modified (304 Not modified and Cache-Control kfiroo/react-native-cached-image#56)
• Responsive image (https://github.com/expo/react-native-responsive-image)

Any news from the RN team? :) It's been a loooong time

[shergin]

It is community driven project, so PRs are always welcome!

[sospedra]

Before make any PR I usually wait until one collaborator tell me that's something needed. I'll take your comment @shergin as a call ;)

[shergin]

Well, honestly I have no any idea why this happening. But... usually code is worth a thousand words.
Is this expected behavior? Probably not. Someone just have to investigate this.

I had the same issue with FlatList with images on rows. Not only warning but also there are serious performance problems too. I convert it to ListView, its all works great now. There is definitely something going on with FlatList

Having same issues, I am rendering 3 images in a view using images uploaded on cloudinary

I'm also experiencing this while loading images into a flatlist

[Malagasy]

having a similar issue

it works well on android 6 but ios 11.0
actually images called with remote uri aren't displaying at all

has someone found a workaround?

[Malagasy]

ok my bad, images were called with http
switching to https worked for me

I'm encountering the same problem after switching from RN 0.48.4 to 0.52.0.

I get the impression that this is not just a warning. I think that somehow this problem combined with the flat list may be causing some sporadic crashes in my application.

I am using the appsee service and I have noticed that many crashes that are not a JS exception happen to many users when they enter the section of my application where the image list is built.

This is the list of crashes that I have not yet been able to solve, but thanks to appsee I was able to realize that 90% of the time it happens loading theflatist rendering image in each row.

- SIGTRAP
- SIGABRT
- abort_with_payload_wrapper_internal
- pthread_kill$VARIANT$mp

The statistics collected tell me that these crashes happen around 1 per week. As you can see, it's something super sporadic.
