The AWS SDK for Go has received an important update to align with Go 1.8. This update addresses a critical issue where certain API operations encountered a connection reset by peer error or other service-related errors, leading to a failure in processing API requests. Users operating with Go 1.8 and versions of the SDK prior to v1.6.3 must upgrade to at least v1.6.3 to benefit from this fix.
The underlying problem was identified in GitHub issue #984, which revealed that the bug stemmed from how the SDK constructed its HTTP request body. Previous versions of the SDK depended on undocumented features present in Go 1.7 and earlier. Specifically, the Go http.Request automatically determined whether to send a request’s body based on whether it was empty.
In Go 1.8rc2, the issue was addressed for most scenarios; however, some APIs—including the Amazon Simple Storage Service (Amazon S3) CopyObject API—were still impacted. The SDK’s resolution leverages Go 1.8’s new type, http.NoBody, which ensures that the HTTP request omits a body when none is required. An alternative approach of setting Request.Body to nil was considered but would have broken backward compatibility since the Request.Body value can be accessed.
