I can imagine a s I added "generated" to the file name. http://gerrit.cloudera.org:8080/#/c/13807/15/be/src/util/vectorised_bit_unpacking_generator.py File be/src/util/vectorised_bit_unpacking_generator.py: http://gerrit.cloudera.org:8080/#/c/13807/15/be/src/util/vectorised_bit_unpacking_generator.py@5 PS15, Line 5: > Can you extend this comment? The following info could be useful: Added the required comments. About the mini smoke test: I think including just one example function has limited usefulness for testing purposes. Another difficulty is that we run the generated source file through clang-format, so comparing the generated raw function with the example taken from the file may be more difficult as they are not the same string, so we would need to run clang-format on the generated function, too. -- To view, visit http://gerrit.cloudera.org:8080/13807 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I9e452a547973778bbd8d768c608e1a32e948f947 Gerrit-Change-Number: 13807 Gerrit-PatchSet: 17 Gerrit-Owner: Daniel Becker <[email protected]> Gerrit-Reviewer: Csaba Ringhofer <[email protected]> Gerrit-Reviewer: Daniel Becker <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-Comment-Date: Fri, 26 Jul 2019 15:51:44 +0000 Gerrit-HasComments: Yes
