Source: epydoc Version: 3.0.1+dfsg-11 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: randomness X-Debbugs-Cc: reproducible-builds@lists.alioth.debian.org
Hi! While working on the “reproducible builds” effort [1], we have noticed that class trees written by epydoc list classes in an order that varies across builds. The attached patch uses a total order on classes (orders on class name, then module, then package, then parent package, etc.) instead of a partial one (only class name). It also added ordering for modules. Once applied, more packages using epydoc can be built reproducibly in our current experimental framework.
