Classify a uvr failure for retry decisions

Retries transient network/IO failures; fails fast on dependency resolution and compile errors, which are deterministic and would burn every retry attempt for nothing. A message that mentions both a transient and a deterministic cause is treated as deterministic (fail fast).

Usage

classify_uvr_error(error_msg)

Arguments

error_msg

(character)
Error message string for classification

Value

List with should_retry (logical) and error_type (character)
