From 0783b9e81328729353cfad7ec25391c03d7f772a Mon Sep 17 00:00:00 2001 From: László Csomor Date: Fri, 11 Aug 2017 10:28:36 +0200 Subject: Rewrite //:combine_distfiles.sh in Python It can only pack to zip for now (packing to tar is not trivial and I haven't figured it out yet). This allows building //:bazel-distfile on Windows. Previously it was either timing out or taking so long that it was unbearable (over 10 minutes). I never waited long enough to see it build. The new Python version runs under just a few seconds.
