Review: dae-py-relay-controller 1.5.2-1

Package Information

Description	Library for controlling Denkovi DAE USB relay boards This is a library that uses libftdi to direct access Denkovi USB relay controller boards such as the DAE-CB series (4, 8 or 16 relay). Known Limitations and Assumptions: * 4 and 8 relay boards do not handle connection to multiple devices. Connects to first found Denkovi. * Not thread safe. * Possible race conditions with device plugging. * Uses a VCP delay of 50ms. Documentation specifies 5ms but was still seeing corruption at 20ms. Could be improved for the gets by doing an initial sync and then keeping track of the states in the class.

Final Comment

Hi,

Some issues, notably the license is not fully present in debian/copyright.

[important] [packaging] Missing runtime dependency on python3-serial for the VCP (16-relay) transport

Files: debian/control, dae_RelayBoard/dae_RelayBoard_VCP.py:23
Evidence: dae_RelayBoard_VCP.py:23 has import serial; Depends: ${python3:Depends}, ${misc:Depends}, python3-pylibftdi lists no serial provider.
Problem: The DAECB-16 board is driven through dae_RelayBoard_VCP (documented in README via example16.py/test16.py), which imports the serial module at module level. Without pyserial installed the call fails at runtime with ModuleNotFoundError: No module named 'serial'. Policy 7.2 requires Depends for anything needed to provide significant functionality. The import is lazy so the package installs and the import smoke test passes regardless, which masks the gap.
Fix: Add python3-serial to the binary package Depends.

[important] [licensing] Reproduced licence text in debian/copyright omits the warranty-disclaimer paragraph and is incorrectly named

Files: debian/copyright
Evidence: The License: dae-py-relay-controller paragraph ends at "included in all copies or substantial portions of the Software.", while every source header and README.md continue with "THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY ... OUT OF OR IN CONNECTION WITH THE SOFTWARE."
Problem: Policy 12.5 requires a verbatim copy of the distribution licence in the copyright file, and copyright-format 1.0 section 6.7 says the License field "should include all text needed ... to fulfill ... any license requirements to include warranty disclaimers". The text as shipped is a truncated Expat/MIT notice; the non-standard short name dae-py-relay-controller is used for a licence that copyright-format section 7.1 says to call Expat when it matches.
Fix: Complete the License paragraph with the disclaimer and use the standard short name Expat.

[minor] [packaging] Patches lack complete DEP-3 headers

Files: debian/patches/setuptools-instead-of-distutils.patch, debian/patches/pylibftdi-0.23-returns-strings-now-not-bytes.patch
Evidence: setuptools-instead-of-distutils.patch is a bare diff with no DEP-3 metadata; pylibftdi-0.23-returns-strings-now-not-bytes.patch has From/Subject/Forwarded but no Description: (or Origin/Last-Update).
Problem: This is not a build failure, but the DEP-3 tagging spec (BTS 979632) asks every patch to carry at least a Description so its purpose and origin are traceable without reading the diff; here the setuptools patch's purpose is only inferable from the filename.
Fix: Add DEP-3 headers (Description, Last-Update, and Forwarded/Origin) to both patches.

[minor] [packaging] debian/watch is in the old version 3 format

Files: debian/watch
Evidence: version=3
Problem: Version 5 is the current format of debian/watch.
Fix: Convert it to version 5; a mechanical conversion is suggested below.

==============================================
Version: 5
