Tagging todos that seem to have a plan ready as confirmed. Also closed some old ones for various reasons. Including several that turn out to be addressed by newer features. Also opened a new todo about git-annex-config needing a criteria to add new configs to it.

`git annex sync` and the assistant do a merge of new revs, and then
|
|
download the content of files. However, this means that broken links can
|
|
show up, when a file has changed, or a new file was added. In some
|
|
workflows, the user would prefer not to ever see such broken links
|
|
(or at least never for files that are in the repo's preferred content).
|
|
|
|
So, how about a new mode, that defers updating the work tree until
|
|
the content of everything wanted is available?
|
|
|
|
This could be a annex.merge=downloadfirst setting; it would make sync/assistant
|
|
look at the diff between HEAD and the new rev, and try to get all annexed files
|
|
added in that diff, before merging it.
|
|
|
|
Of course, it could take a long time to get to see a new work tree.
|
|
Might have to download a lot of content.
|
|
|
|
What to do if it fails to download a file's content? Could either
|
|
abort, leaving the current work tree as-is, or could go ahead and merge,
|
|
letting broken links show up in this case. I kind of prefer the abort
|
|
option. But, if the content never reaches any remote, or has gone missing
|
|
entirely, that would make sync never succeed. That could be surprising
|
|
behavior.
|
|
|
|
Probably best to let the user pick either behavior, so
|
|
annex.merge=trydownloadfirst and annex.merge=reqdownloadfirst
|
|
|
|
Let `git annex merge` be used to force a merge, even when content is not
|
|
available.
|
|
|
|
## alternatively
|
|
|
|
What about just making `git-annex sync --content` try to get the content of
|
|
all files before updating the work tree? (The assistant would need changes
|
|
too; it would need to queue all the downloads and trigger a work tree
|
|
update once all the downloads have been tried.)
