-// This class should be used only by the component updater. It is inspired by |
-// and overlaps with code in the extension's SandboxedUnpacker. |
-// The main differences are: |
-// - The public key hash is full SHA256. |
-// - Does not use a sandboxed unpacker. A valid component is fully trusted. |
-// - The manifest can have different attributes and resources are not |
-// transcoded. |
-// |
-// If the CRX is a delta CRX, the flow is: |
-// [ComponentUpdater] [ComponentPatcher] |
-// Unpack |
-// \_ Verify |
-// \_ Unzip |
-// \_ BeginPatching ---> DifferentialUpdatePatch |
-// ... |
-// EndPatching <------------ ... |
-// \_ Install |
-// \_ Finish |
-// |
-// For a full CRX, the flow is: |
-// [ComponentUpdater] |
-// Unpack |
-// \_ Verify |
-// \_ Unzip |
-// \_ BeginPatching |
-// | |
-// V |
-// EndPatching |
-// \_ Install |
-// \_ Finish |
-// |
-// In both cases, if there is an error at any point, the remaining steps will |
-// be skipped and Finish will be called. |
