In the past I've +worked around this by keeping all the disk-reading backwards +compatible (e.g. homemade mapfile -> YAML, the "From" hack in +libbe.comment.Comment.load_settings, possibly others). However, this +is not the road to easily maintainable code. + +Most projects only need to maintain backwards compatibility with the +last few versions of their disk cache, to allow users an easy upgrade +path. The difficulties come with "be diff", which must be able to +read _every_ disk-image of the bugdir ever committed into something +comparible with the current cutting edge. This makes sweeping changes +very difficult. VCSs themselves avoid this by never showing their +disk-cache to another program, but we've shown ours to the VCS, and +it's difficult (or impossible, depending on the VCS) to change history +to match the current format. diff --git a/.be/bugs/51930348-9ccc-4165-af41-6c7450de050e/comments/f1479ecf-4154-4cd4-bbd6-0ed6275b9f98/values b/.be/bugs/51930348-9ccc-4165-af41-6c7450de050e/comments/f1479ecf-4154-4cd4-bbd6-0ed6275b9f98/values new file mode 100644 index 0000000..3d4d9df --- /dev/null +++ b/.be/bugs/51930348-9ccc-4165-af41-6c7450de050e/comments/f1479ecf-4154-4cd4-bbd6-0ed6275b9f98/values @@ -0,0 +1,8 @@ +Author: W.
