lfs: infer the blob store URL from an explicit push dest or default-push
Unlike pull, the blobs are uploaded within the exchange.push() window, so simply
wrap it and swap in a properly configured remote store. The '_subtoppath' field
shouldn't be available during this window, but give the passed path priority for
clarity.
At one point I hit an AttributeError in one of the convert tests when trying to
save the original remote blobstore when the swap was run unconditionally. I
wrapped it in a util.safehasattr(), but then today I wasn't able to reproduce
it. But now the whole thing is tucked under the requirement guard because
without the requirement, there are no blobs in the repo, even if the extension
is loaded.
test merging things outside of the sparse checkout
$ hg init myrepo
$ cd myrepo
$ cat > .hg/hgrc <<EOF
> [extensions]
> sparse=
> EOF
$ echo foo > foo
$ echo bar > bar
$ hg add foo bar
$ hg commit -m initial
$ hg branch feature
marked working directory as branch feature
(branches are permanent and global, did you want a bookmark?)
$ echo bar2 >> bar
$ hg commit -m 'feature - bar2'
$ hg update -q default
$ hg debugsparse --exclude 'bar**'
$ hg merge feature
temporarily included 1 file(s) in the sparse checkout for merging
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
Verify bar was merged temporarily
$ ls
bar
foo
$ hg status
M bar
Verify bar disappears automatically when the working copy becomes clean
$ hg commit -m "merged"
cleaned up 1 temporarily added file(s) from the sparse checkout
$ hg status
$ ls
foo
$ hg cat -r . bar
bar
bar2
Test merging things outside of the sparse checkout that are not in the working
copy
$ hg strip -q -r . --config extensions.strip=
$ hg up -q feature
$ touch branchonly
$ hg ci -Aqm 'add branchonly'
$ hg up -q default
$ hg debugsparse -X branchonly
$ hg merge feature
temporarily included 2 file(s) in the sparse checkout for merging
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
