This series seems to build a whole new build system that uses Plan 9 tools. Typically the way ports to non-POSIX platforms (such as Windows) have been handled is that the Unix tools, including GNU make, have been ported to those platforms, and the POSIX (or POSIX-ish) environment used there. I'm concerned that by introducing a whole bunch of new, Plan 9-specific build code, we're going to have it fall behind with features or bug fixes, because none of the main developers test on Plan 9, and most contributors will not have the Plan 9 skills or systems to maintain the code. In addition, the editor used by git commit and other commands invokes "sh", but you've set this to "rc". That's completely different from the way that all other environments work, and it means that Git on Plan 9 operates in a totally different, incompatible way there. We also use a POSIX shell for the testsuite, and we rely on it quite heavily. rc is not going to cut it there. Plan 9 has a POSIX environment, and I think it might be a better idea to require that as a condition for building and running Git. It will likely be a lot easier, at least. --=20 brian m. carlson: Houston, Texas, US OpenPGP: https://keybase.io/bk2204 --cVp8NMj01v+Em8Se Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.2.17 (GNU/Linux) iQIzBAABCgAdFiEEX8OngXdrJt+H9ww3v1NdgR9S9osFAl1GKPgACgkQv1NdgR9S 9oubCw//Yx45/jOjzOlY1d7uPf1xhLoAm6gEcYD23X799GewNWKYJfAvWOJUX/4Q 8aWWgvcqyI+haQxNb9LTeeJIVnBTaW9NfjoLMFP1Cc7tDMMAyg2vOukaWjq517G9 6iM66aq3ZbeeZhXG078JPj83/1qs9Rs4uVRiPXgjN1WTk3cPE1fREFOmNEh23ldA dUE2ij57uVfb6t1NNiCMUEqofTnSODsC7alZdUhlc4I8dp8pnK1o4JOitnQFGOD3 LlYNzsO0Gt9/+NosWWE7m70l6GkbYPIw6RYgpBn4Ehmf+6ut2fqsb3JcgsiS54F6 NCLwUK3g1PZeQypcm9vnNMZ78bljsl1oqAEfOeeXSsx6L9lCASWAqgUylsftw7RS 0h9V2co75ro5choSSezMod0TV+zIB0qKv4S7SswYXLmMp3X+VDySc/iC7Dn33/bq Vqhh7oTKt+C+7p57chKFoovdKKFnP0k2o66VUv55UDZEosO8iKgL7CcRdDPkNOST xSw3trAOQBRFWlbwKOiUx0cslA2rq1CSyYEFeBNNd3cBELnZ9ah+Wtqsy3wqtQwT atbkIY9nJkgieqa2ggQKLMBzkKj5ovaXH6HAwCc0/HWOAj6D5mIZ5Tml71Ldwdum ZV6aV1BidhX89SOZXls8RcSNEgCqEUG1k5m6OL3y8QJpoUQDYz4= =/4Uy -----END PGP SIGNATURE----- --cVp8NMj01v+Em8Se--
