            Why does some garbage not get collected when forcing a GC sweep in Kotlin JVM, depending on seemingly irrelevant factors?
            Asked 2022-Mar-26 at 23:01

            Context

            I'm working on a Kotlin program which runs on the JVM and consumes large amounts of memory. While I do trust the garbage collector to (eventually) free memory used by objects which are no longer reachable, I don't trust future maintainers of the project (including my future self) – especially as the project progresses and becomes more evolved - to write the code in a way that makes sure that objects which are no longer needed are indeed unreachable.

            So in order to reduce the risk, as part of my testing suite (which is already exhaustive with regards to the logic of the program's functionality) I'm also writing (or trying to write, with different degrees of success) various tests which aim to ensure that references aren't kept to objects which have run their course.

            As this is quite difficult to do directly, the technique I'm using in the tests is to employ objects with finalizers, simulate the conditions when they're no longer needed, force garbage collection, and assert the finalizers have indeed run. (Note: my question is not about this technique per se, but if someone has comments or ideas for improvement or can propose alternatives – I'll be interested to hear!).

            This generally works well, and can be shown to do the job, e.g. in TDD style: I write naive code which does the job as far as the business logic is concerned but doesn't take care of losing references to old objects, I write a test as described above, I make sure that the test fails, I add code to take care of memory (e.g., in simple cases, set references to null), and then see that the test passes.

            My question

            For some reason, my tests don't always work (clarification: I don't mean that they fail non-deterministically; I mean that some of the tests consistently work and some consistently fail). The real examples from the project contain lots of intricate, proprietary details, but I've managed to boil it down to the following minimal example:

            Type guard for union type generic notification (Notifier | Success) does not work
            Asked 2022-Mar-26 at 21:56

            I have the following structure:

            ...

            ANSWER

            Answered 2022-Mar-26 at 21:56

            The core of the problem here is that Success and Notifier are both structurally the same, so TypeScript thinks that if the following if statement has a chance of returning true for one of those classes, it would return true for both:

            if(result.isFailure())

            Hence, the result value type after this block is automatically inferred as never. I have created an example to illustrate this here.

            This problem can easily be fixed by introducing a unique field/method within one of the two classes or alternatively adding a private field/method.

            The explanation above will fix the issue you are having and can be used to describe the behaviour of the if(result.isFailure()) statement. However, if(result.isSuccess()) on the other hand still appears to work with your original code. The reason for that is because you have introduced dynamicity in the order of how the nested generic types are assigned to the extending classes:

            extends ResultAbstract vs extends ResultAbstract

            Given the above, the classes can be considered to be different, however TypeScript will still think that Success and Notifier are the same as the is predicates tell it that Success can be Notifier (via the isFailure method) and Notifier can be Success (via the isSuccess method). Hence, all you need to do is remove either the isSuccess or the isFailure method and the code will start to work as it will tell TypeScript that it can only be one. Because your code only uses two classes, this would be the most suitable solution.

            Compress & Upload large videos to Google cloud storage using Flutter/Dart
            Asked 2022-Feb-20 at 03:41

            There are a couple of notable packages on pub.dev that offer video compression. I've tried them, and other sketchy packages, and none work well once a video gets around 300MB. They crash or have other issues on various platforms and hardware. Namely, video compress and light compressor. The GH commits and support are concerning as well on the packages I've seen for video compression in pub.dev. PR's not being pulled in and issues not being resolved in a timely manner and some quite serious for recent android APK updates. So not something I want in my dependency stack.

            I am uploading to Google Cloud Storage using FlutterFire. While my code does upload using FireBaseStorage upload task it does not have any ability to compress on the client side or handle background uploading when the app is closed.

            So, currently on the server side, I have a GCF that triggers on file uploaded. Then I use nodejs ffmpeg, which is baked into GCF's to compress server side and convert to H264. And finally delete the original large upload video and save the compressed video to storage.

            This solution works, but depending on a user's connection and whether they are on wifi, can take an awful long time and when it fails or the user closes the app, my current solution is useless.

            I wish there was a solid native library on Android and iOS, that I could tap into, to confidently perform compression and conversion from any format to H264 and also allow uploading, whether my app is closed or in the background, to GC storage. Any thoughts? I wish this was standard in FlutterFire's cloud storage handling!

            I have yet to test flutter_ffmpeg, but only because some have said it runs so slowly on client. So again, Flutter/Dart can access natively written code, but I don't know where to start on Android/iOS to do this the right way. And I understand this is what some of the packages are doing, but they do not work with large videos, so I'm hoping someone can point me in the right direction on Android and iOS.

            My code for handling upload tasks to GC storage.

            Answered 2022-Feb-20 at 03:41

            I did resolve, to some degree, my original post's questions and frustrations by using the ffmpeg_kit_flutter_full_gpl package on the client side, and then ffmpeg again in GCF on the server side. In summary:

            • Within 60 seconds, I can now compress a 2 minute video by 90% before uploading to firebase storage.
            • Using onFinalize via GCF on the server side I run ffmpeg again on the uploaded video and gain another 77% reduction in file size on the server side without any loss in video quality.
            • My solution does not yet upload while the app is closed.
            • On the client side, this solution requires setting the camera ResolutionPreset to high (720p), rather than max, which can be a minimum of 1080p, and setting the ffmpeg -preset veryfast rather than the medium default.

            Camera & ffmpeg solution settings:

            Transcoding results stats for 2 minute video:

            • Before transcode: 255MB
            • After client side transcode: 25MB (90% decrease in size before upload)
            • Time to transcode: 60 seconds
            • onFinalized GCF ffmpeg transcode: 19MB (77% reduction in size)
            • In total a 93% reduction in size while keep high quality 720p video.

            flutter_ffmpeg is archived, the new ffmpeg flutter package is ffmpeg_kit_flutter.

            That being said, I used ffmpeg_kit_flutter to build my solution on the client side, rather than the server side, and transcode the video before uploading.

            Cons:

            1. Doubled my app size to use ffmpeg, because I needed access to both lame and x264 so I had to install the full-gpl package to gain access to these libraries.
            2. A two minute video can take up to 60 seconds to transcode.

            The pros:

            1. Low bandwidth connections will operate much better after a video is reduced in size by 90%.
            2. Large videos will transcode and ffmpegkit does not crash like other flutter packages I've tried.
            3. The second pass with ffmpeg on GCF gains another 77% reduction in size taking a video of 100's of MB's down to just 10-20 MB max for eventually delivery.
            4. Costs lower on the front and back end.

            So, you'll have to decide if the pros outweighs the cons and if 720p is high enough quality for playback. For me 720p looks perfect for video playback on a mobile phone and 1080p or higher was big time overkill.

            I've provided sample code (not full classes) to give anyone looking to implement my solution a try. It became very important, due to the amount of time to transcode, to display a progress meter so the user does not give up on the process. You'll see my simple solution to displaying transcoding progress.

            XFile is a image_picker package's wrapper for the picked file(s). Hence, you obtain a List from await ImagePicker().pickMultiImage() call, but try to assign it to a _selectedPostImages field that expects List which produces the type mismatch error.

            So, you can either:

            1. Rewrite the _selectedPostImages to expect List, like List? _selectedPostImages.
            2. Map the _imageList to a list of File, like _selectedPostImages = _imageList.map((xfile) => File(xfile.path)).toList()
