Breakpad symbol generation failed for Unity 6 symbols

[FrantisekHolubec]

[REQUIRED] Environment info

firebase-tools: 13.23.0

Platform: Windows 11

[REQUIRED] Test case

I tried to upload the symbols for my unity 6 app but it fails. its failing only for symbols made by unity 6
Is this unity problem, am I doing something wrong or is this a bug ?
I tried with 2 different java version and get 2 different errors.

[REQUIRED] Steps to reproduce

problematic file: https://drive.google.com/file/d/1rR9b9Pt7gwbfvePiUneL-RwRgPj5i39w/view?usp=sharing
attempt to upload symbols

firebase crashlytics:symbols:upload --debug --app=1:187029196205:android:e8b5c9e6935cf6bb11a524 ./TA_TankSurvivor_Release_v.0.02.01.506-0.02.01-v201-IL2CPP.symbols.zip

firebase crashlytics:symbols:upload --debug --app=1:187029196205:android:e8b5c9e6935cf6bb11a524 ./TA_TankSurvivor_Release_v.0.02.01.506-0.02.01-v201-IL2CPP.symbols.zip --generator csym

Thanks for reporting this @FrantisekHolubec. I am able to reproduce this.

For now, you can work around this by manually unzipping the symbols, and removing all libFirebaseCpp* files from each arch.

I think this behaviour might be new, I don't remember Unity including Firebase libs in the output. I will update our build tools to handle it, but it will likely not get released until next year. If this workaround does not work for you, I can build you a prerelease of the build tools binaries.

[FrantisekHolubec]

Thank you @mrober removing libFirebaseCpp* files worked, I integrated it into our pipeline until the new version gets released.

[UnwindGamesDeveloper]

Any ETA for this fix ?

[shokarta]

also experiencing same issue in #6633... any update?

[FrantisekHolubec]

I am using TeamCity for building so I made a simple Python method to fix the symbols, sharing until the fix comes out:

import os
import shutil
import zipfile

def fixFirebaseSymbols(zip_path):
    prefix = "libFirebaseCpp"
    temp_zip_path = zip_path + ".tmp"

    # Temporary storage for files to keep
    files_to_keep = []
    skip_fix = True

    with zipfile.ZipFile(zip_path, 'r') as zip_ref:
        compression_method = zip_ref.getinfo(zip_ref.namelist()[0]).compress_type
        for file_name in zip_ref.namelist():
            if not os.path.basename(file_name).startswith(prefix):
                files_to_keep.append((file_name, zip_ref.read(file_name)))
            else:
                skip_fix = False

    if skip_fix:
        print("No need for fixing symbols.")
        return

    # Write the filtered files into a temporary ZIP file with the original compression method
    with zipfile.ZipFile(temp_zip_path, 'w', compression=compression_method) as zip_ref:
        for file_name, file_data in files_to_keep:
            zip_ref.writestr(file_name, file_data)

    # Replace the original ZIP file with the modified one
    shutil.move(temp_zip_path, zip_path)

I have a fix for this in the latest Crashlytics buildtools, it will be included in the next version of the Firebase CLI tool. For now you can manually tell it to use the latest buildtools by:

1. Download firebase-crashlytics-buildtools-3.0.3.jar.

2. Tell the Firebase CLI tool to use the downloaded jar by setting the environment variable:

   export CRASHLYTICS_LOCAL_JAR=/path/to/firebase-crashlytics-buildtools-3.0.3.jar

3. Run the Firebase CLI tool in debug mode to verify it's using the downloaded jar:

   firebase crashlytics:symbols:upload --debug --app=FIREBASE_APP_ID /path/to/symbols

[shokarta]

hello @mrober Im not sure if this also fixes firebase/firebase-android-sdk#6633,
should it also fix?

[joehan]

Closing this since the PR is merged - it will be included in the next firebase-tools release sometime next week.

[arongeorgel]

Coming here from this issue - firebase/firebase-android-sdk#6633

I faced a similar issue where setting the upload to false would not work in my build.gradle.kts (not using groovy). I'm not sure if will be fixed as part of this or if i should open a new issue.

using crashlytics plugin 3.0.1
google services 4.4.2

firebaseCrashlytics {
     mappingFileUploadEnabled = false
}

but using what i see as "old" syntax works

configure<CrashlyticsExtension> {
     mappingFileUploadEnabled = false
}

My build is failing as i'm building 100% offline

[mrober]

@arongeorgel the configure<CrashlyticsExtension> syntax is correct for kts. Is your build working with that? If not, please file a new issue in the Firebase Android SKD repo.

[arongeorgel]

@mrober gotcha! yes, that is working for me.
