Download resumption - Githubissues

wvmarle commented 11 years ago

Complete download resumption using the --resume option.

So what we have now (assume retrieving done):

$ glacier-cmd download <vault> <archive_id> --outfile=<file_name>

Download archive to file_name. If file exists: throw an exception and quit.

$ glacier-cmd download <vault> <archive_id> --outfile=<file_name> --overwrite

Overwrite the existing file_name, if any.

$ glacier-cmd download <vault> <archive_id> --outfile=<file_name> --resume

Attempt to resume download of archive to file_name. Checks:

download not complete yet (file size matches archive size, then hash check of complete file).
check part hashes of the file to the part hashes of Amazon, using the biggest part possible for minimum number of checks. If all checks out, download is resumed.

Documentation needs updating to reflect all this.

Will you do it or do I just merge?

wvmarle commented 11 years ago

Also rebased.

Will update docs when all changes are done and implemented, so can do that in one go.

Conflicts galore - this also did stuff to upload - all now included in parallel_uploads branch.
