It's very easy to extend. However, there +is only so far you can go with generic support.

However, I really like the simplicity of + `be init` +and the ability to postpone repository customization until you need +it. So, can we trim down the BE internals to make BE more extensible +without sacrificing our nice default setup and its tools? The problem +is, how to the commands do their thing if they don't know what they're +working with? + +Say, for example, I want to run `be depend bugA bugB`, but my bugs +don't have blocks or blocked_by link properties. That could be easily +handled by having each command would have to keep track of which +properties it needed and raise appropriate exceptions. + +List, Show, Import_xml, etc. would presumably use templates to define +their output/input formats. + +As far as postponed customization goes, it would be easy enough to +duplicate Roundup's schema.py and provide a default schema.py for +bugtracking. This would improve our current system by keeping all the +configurable bits under version control from the start (equivalent to +setting _versioned_property(require_save=True) for all properties). + +Another part of the difference between BE and Roundup seems to be due +to the initial backend selection. Roundup is built on databases, +which encourages their keyed-Class approach with (property, value) +pairs of predefined types. They use Classes for everything, down to +status values, etc., while we've built those sorts of things into +_versioned_property()s. +Benefits of Roundup approach: + * easy to configure/alter/retrieve list of allowed values + * no need to hard-code properties or resort to extra_strings + * assigned values are actually links to centralized definitions + - easy updates +Benefits of BE approach: + * single file for all properties + - one read and you're done + - many file systems don't handle 'lots of tiny files' well + * assigned values are actual values, not links to centralized defs. + - easy to merge by hand, no need to look up references. +Since it would be fairly simple to add a merging tool that handled the +reference lookup transparently, we can move to a Roundup-like Class +structure by using our current mapfile implementation to store small +Classes. + +Finally, would it be easier to merge these Roundup features into BE, +or merge the BE features into Roundup... + diff --git a/.be/bea86499-824e-4e77-b085-2d581fa9ccab/bugs/814e39c0-68ee-4165-9166-19e2aee9c07d/comments/d463e2d9-6dcc-41a4-a6b2-647fb3bddf88/values b/.be/bea86499-824e-4e77-b085-2d581fa9ccab/bugs/814e39c0-68ee-4165-9166-19e2aee9c07d/comments/d463e2d9-6dcc-41a4-a6b2-647fb3bddf88/values new file mode 100644 index 0000000..cb7278c --- /dev/null +++ b/.be/bea86499-824e-4e77-b085-2d581fa9ccab/bugs/814e39c0-68ee-4165-9166-19e2aee9c07d/comments/d463e2d9-6dcc-41a4-a6b2-647fb3bddf88/values @@ -0,0 +1,8 @@ +Author: W.
