Diff Update not working for subsequent codepushes. Entire bundle is always downloaded

[gogul-ct]

Steps to Reproduce

1. Code push a fix v1
2. Code push another fix v2 on to same binary version

Expected Behavior

Diff must happen and only changed files should be downloaded

Actual Behavior

Entire bundle is always getting dowloaded

Environment

• react-native-code-push version: ^7.0.4
• react-native version: 0.67.2
• iOS/Android/Windows version: All Android & iOS versions

We are also uploading sentry maps.

Should any naming convention or file structures to be followed for diffing to work?

Also seeing this in an existing app.

We monitor totalBytes on codepush sync, and starting on August 15, every update is now a full download.

Are you guys experiencing extremely slow bundle downloads?

[saransh-malik]

Yes, facing both full download issue as well as very slow download speeds.

Hello,

I am working on an app with a lot of users in Latin America where internet is slow and expensive, and we are facing this issue as well. I've been reading all I can about this, github issues, blogs, documentation, even the server code related to this.

https://github.com/microsoft/react-native-code-push/blob/9947037a985a04927c64624318e4ce64d43d2049/windows-legacy/CodePush.Shared/CodePushConstants.cs#L11

A file called hotcodepush.json seems to be necessary for the diffing logic?

And the server seems to look for it in the main dir. I downloaded our current staging version from appcenter and unzipped the contents, and I'm not seeing any hotcodepush.json file. Here's what I have:

➜  app-staging-release find . | grep hotcodepush
➜  app-staging-release

This is how we release the update:

    command = 'yarn appcenter codepush release-react '
    command += "--token #{token} "
    # here's the force cache flush:
    command += '--extra-bundler-option="--reset-cache" '
    command += "--app #{APPCENTER_ORG_NAME}/#{app_name} "
    command += "--deployment-name #{APPCENTER_DEP_NAME} "
    command += "--target-binary-version '#{target}' "
    # explicitly tell where to output build and sourcemaps
    command += '--output-dir ./build '
    command += '--sourcemap-output-dir ./build '
    command += "--description #{description} "
    command += '--mandatory '
    command += '--disable-telemetry '
    command += '--disable-duplicate-release-error'

I would really appreciate any help in debugging this. Let me know if there's any more info I can provide.

@cmocanu I thin they just don't care about codePush. Its a free product, so they just don't care. Here the problem seems to be in some networks. Some work, some doesn't

any updates?

[vasteez]

Same question here. Differential logic seems to depend on hotcodepush.json but this is not generated and no info on how to generate it. I am running the react-native bundle command
