lines of code of the release. The final result of this step is the list of packages (and the files composing them) that we consider for analyzing the size of a Debian release. This list is done by hand (with simple scripts) for each release. 3.2 Downloading and collecting data Once the packages and files composing Debian 3.0 are determined, they are downloaded from some server of the net of Debian mirrors. Some process, which (for each package) consists of the following phases: • Downloading of the files composing the package • Extraction of the source directory corresponding to the upstream package (by untaring

the framework more efficient because it does not have to do any kind of conversion or lookup when composing the WSGI response. If not set explicitly, the status defaults to ‘200 OK’. Note Falcon provides has_representation bool – Read-only property that determines whether error details will be serialized when composing the HTTP response. In HTTPError this property always returns True, but child classes may override include a WWW- Authenticate header field containing at least one challenge. The performance of composing the response body was improved. As part of this work, the Response.body_encoded attribute was removed

In ``HTTPError`` this property always returns ``True``
