Separate multipart completion logic for azureblob and azureblob-sdk providers. The new azureblob-sdk validation path introduced in 2.9.0 inadvertently broke the legacy azureblob provider by validating part numbers against client requests, while azureblob uses synthetic part numbers (divided by 10000). Changes: - handleCompleteMultipartUpload: azureblob uses simple listMultipartUpload iteration, while azureblob-sdk validates and deduplicates parts from XML request - handleListParts: scope the part-number aggregation to azureblob only Fixes multipart upload failures for files >5.2MB with azureblob provider.

Summary
azureblobprovider multipart upload behavior to pre-2.9.0 logic, fixes Uploading files >5.2mb to Azure Blob Storage fails since 2.9.0 release #929Problem
The
azureblob-sdkmultipart upload implementation (commit fb96699) broke the legacyazureblobprovider by validating part numbers against the client's CompleteMultipartUpload XML request.The
azureblobprovider uses synthetic part numbers (10_000 * partNumber + subPartNumber) to split large S3 parts into smaller Azure blocks. When the new validation logic looked up client-provided part numbers (1, 2, 3...) in a map containing Azure block numbers (10000, 10001...), no match was found, causingINVALID_PARTerrors.Changes
handleCompleteMultipartUpload: Restoreazureblobto its original simple iteration logic;azureblob-sdkretains the new XML parsing + validation pathhandleListParts: Scope the/10_000part-number aggregation toazureblobonly, allowingazureblob-sdkto use direct part numbers. This bug did not surface yet because usually this is not used.This ensures the new
azureblob-sdkimplementation does not affect the deprecatedazureblobprovider and theazureblobpart-number magic does not affect the newazureblob-sdkprovider.
