I've lost track of them all, but it includes:
* Using the same key backend as was used in the original computation.
* Fixing bug that prevented updating the source file key in the compute
state
* Handling --reproducible and --unreproducible.
* recompute --original of a file using VURL, when the result is
different, but the key remains the same, makes the object file
be updated with the new content
* Detecting some other ways the program behavior can change, just for
completeness.
* Also adds --backend to addcomputed.
When a computed file has been renamed, a recompute needs to write to the
new filename.
I decided to remove --others because it's not clear what it should do in
the face of renames. Should it update only other files that have not
been renamed? Or update files that use the old key to the new key
anywhere in the tree? Or write the other files to the cwd, ignoring
renames? Since --others is just a way to save on compute time, adding
this complexity at this point seems like a bad idea. May revisit later.
Added temporary TODO-compute file
Proper behavior without --others implemented.
And eliminated most of the code duplication through refactoring.
Also, changed it to not stage recomputed files. This way, git diff will
show files that have differences.
The perform action of this still needs work to do the right thing.
In particular, it currently behaves as if --others was always set.
And, it duplicates a lot of code from addcomputed.
