This is a summary todo covering several subprojects, which would extend
|
|
git-annex to be able to use proxies which sit in front of a cluster of
|
|
repositories.
|
|
|
|
1. [[design/passthrough_proxy]]
|
|
2. [[design/p2p_protocol_over_http]]
|
|
3. [[design/balanced_preferred_content]]
|
|
4. [[todo/track_free_space_in_repos_via_git-annex_branch]]
|
|
5. [[todo/proving_preferred_content_behavior]]
|
|
|
|
Joey has received funding to work on this.
|
|
Planned schedule of work:
|
|
|
|
* June: git-annex proxy
|
|
* July, part 1: git-annex proxy support for exporttree
|
|
* July, part 2: p2p protocol over http
|
|
* August: balanced preferred content
|
|
* September: streaming through proxy to special remotes (especially S3)
|
|
* October: proving behavior of balanced preferred content with proxies

# work notes
|
|
|
|
In development on the `proxy` branch.
|
|
|
|
For June's work on [[design/passthrough_proxy]], implementation plan:
|
|
|
|
* UUID discovery via git-annex branch. Add a log file listing UUIDs
|
|
accessible via proxy UUIDs. It also will contain the names
|
|
of the remotes that the proxy is a proxy for,
|
|
from the perspective of the proxy. (done)
|
|
|
|
* Add `git-annex updateproxy` command and remote.name.annex-proxy
|
|
configuration. (done)
|
|
|
|
* Remote instantiation for proxies. (done)
|
|
|
|
* Implement git-annex-shell proxying to git remotes. (done)
|
|
|
|
* Proxy should update location tracking information for proxied remotes,
|
|
so it is available to other users who sync with it. (done)
|
|
|
|
* Consider getting instantiated remotes into git remote list.
|
|
See design.
|
|
|
|
* Implement single upload with fanout to proxied remotes.
|
|
|
|
* Implement clusters.
|
|
|
|
* Support proxies-of-proxies better, eg foo-bar-baz.
|
|
Currently, it does work, but have to run `git-annex updateproxy`
|
|
on foo in order for it to notice the bar-baz proxied remote exists,
|
|
and record it as foo-bar-baz. Make it skip recording proxies of
|
|
proxies like that, and instead automatically generate those from the log.
|
|
(With cycle prevention there of course.)
|
|
|
|
* Cycle prevention. See design.
|
|
|
|
* Optimise proxy speed. See design for ideas.
|
|
|
|
* Use `sendfile()` to avoid data copying overhead when
|
|
`receiveBytes` is being fed right into `sendBytes`.
|
|
|
|
* Encryption and chunking. See design for issues.
|
|
|
|
* Indirect uploads (to be considered). See design.
|
|
|
|
* Support using a proxy when its url is a P2P address.
|
|
(Eg tor-annex remotes.)
