Doesn't work on Codemagic

[TheCarpetMerchant]

I'm getting this error when running the flutter pub run sentry_dart_plugin command in the post-build script on Codemagic (ios build) :

error: Could not find the SHA of the previous release in the git history. If you limit the clone depth, try to increase it. Otherwise, it means that the commit we are looking for was amended or squashed and cannot be retrieved. Use --ignore-missing flag to skip it and create a new release with the default commits count.

All the uploads appear to have gone well aside from the set-commits command.

@TheCarpetMerchant hi, can you share your config? (feel free to remove any sensitive info)

@TheCarpetMerchant hi, can you share your config? (feel free to remove any sensitive info)

Sentry config is barebones :

sentry:
  project: project
  org: org
  auth_token: token
  # Absolute or relative path to the Dart symbol map file
  # Used to make obfuscated Flutter issue titles readable on iOS and Android
  # See the "Building Your Application" section below for more details on how to generate the symbol map file
  # Available since version 3.2.0 of the Sentry Dart Plugin
  # Only applicable for obfuscated builds
  dart_symbol_map_path: build/app/obfuscation.map.json
  symbols_path: build/app/symbols
  log_level: info

I'm using the codemagic workflow so I don't have a yaml for that.

I'm building with the options --release --obfuscate --split-debug-info=build/app/symbols --extra-gen-snapshot-options=--save-obfuscation-map=build/app/obfuscation.map.json

Then running in a post build script :
flutter pub run sentry_dart_plugin

Works perfectly fine on my laptop, and the codemagic VM should have git access since it can pull from my private repos just fine when pub get is run before the build.

Thanks for the config, we'll have a look

@TheCarpetMerchant It looks like the full commit history is not checked out per default on codemagic, judging from the error message alone. I did not re-produce this, but checked docs and found CM_CLONE_UNSHALLOW env var, which should check out the whole history if set to true. If feasible in your setup, you could try to set it in your config: https://docs.codemagic.io/yaml-basic-configuration/environment-variables/

Alternatively, you can ignore missing:

sentry:
  ignore_missing: true

With this build won’t fail if Sentry can’t find old commits, but commit tracking may be less accurate.

[TheCarpetMerchant]

I tried CM_CLONE_UNSHALLOW and it didn't change anything.

@TheCarpetMerchant Do you get the same error message with CM_CLONE_UNSHALLOW?

Yes, the exact same

[denrase]

I tried to repro your setup on codemagic, everything works as expected. There are two things you could check.

In the Fetching app source steps, this is what I get per default:

== Cloning repository https://github.com/denrase/flutter-codemagic for main ==
> /usr/bin/git clone --progress --branch main --depth 50 https://denrase@github.com/denrase/flutter-codemagic /Users/builder/clone
Cloning into '/Users/builder/clone'...
remote: Enumerating objects: 106, done.   

And this if I set CM_CLONE_UNSHALLOW to true:

== Cloning repository https://github.com/denrase/flutter-codemagic for main ==
> /usr/bin/git clone --progress --branch main https://denrase@github.com/denrase/flutter-codemagic /Users/builder/clone
Cloning into '/Users/builder/clone'...

Are you seeing the latter checkout, without the --depth 50 param?

If this is not the issue, you could also check if the release commit was on main (or whatever you main branch is called.)

git merge-base --is-ancestor <COMMIT-SHA> origin/main \
  && echo "on main" \
  || echo "not on main"

[TheCarpetMerchant]

I see /usr/bin/git clone --progress --branch master, which is the correct branch.

@TheCarpetMerchant No luck so far in reproducing this. If this is still an issue, it would be great if you could provide us with a minimal repo setup.
