Currently, git-annex takes a very lazy approch to displaying
|
||
|
|
progress into. It just lets rsync or whatever display the progress
|
||
|
|
for it, in the terminal.
|
||
|
|
|
||
|
|
Something better is needed for the [[webapp]]. There needs to be a
|
||
|
|
way for the web app to know what the current progress is of all transfers.
|
||
|
|
|
||
|
|
This is one of those potentially hidden but time consuming problems.
|
||
|
|
|
||
|
|
## downloads
|
||
|
|
|
||
|
|
* Watch temp file as it's coming in and use its size.
|
||
|
|
Can either poll every .5 seconds or so to check file size, or
|
||
|
|
could use inotify. **done**
|
||
|
|
* When easily available, remotes call the MeterUpdate callback as downloads
|
||
|
|
progress. **done**
|
||
|
|
* S3 TODO
|
||
|
|
While it has a download progress bar, `getObject` probably buffers the whole
|
||
|
|
download in memory before returning. Leaving the progress bar to only
|
||
|
|
display progress for writing the file out of memory. Fixing this would
|
||
|
|
involve making hS3 stream better (also avoids it wasting memory).
|
||
|
|
|
||
|
|
## uploads
|
||
|
|
|
||
|
|
Each individual remote type needs to implement its own support for calling
|
||
|
|
the MeterUpdate callback as the upload progresses.
|
||
|
|
|
||
|
|
* git: **done**
|
||
|
|
* rsync: **done**
|
||
|
|
* directory: **done**
|
||
|
|
* web: Not applicable; does not upload
|
||
|
|
* webdav: **done**
|
||
|
|
* S3: **done**
|
||
|
|
* glacier: **done**
|
||
|
|
* bup: TODO
|
||
|
|
* hook: Would require the hook interface to somehow do this, which seems
|
||
|
|
too complicated. So skipping.

|
## communication
|
||
|
|
|
||
|
|
It may be worth using a better communication channel than files on disk for
|
||
|
|
the transfer progress. Shared memory could be used, or http posts to the
|
||
|
|
webapp.
