Subject: [PATCH 0/8] Resumable clone revisited, proof of concept
Date: Fri, 5 Feb 2016 15:57:49 +0700 [thread overview]
Message-ID: <1454662677-15137-1-git-send-email-pclouds@gmail.com> (raw)
I was reminded by LWN [1] about this. Annoyed in fact because it's
called a bug while it looks more like an elephant. So let's see if we
can agree this is a good way to go.
This is the stable pack approach. The client initiates "resumable
mode" and forces the server to generate a resumable, even though less
efficient, pack. Compared to the "download from a cached bundle first"
approach, this requires no extra setup for caching. But it wastes more
cpu.
The UI is not there yet, and you can only resume a fetch, not a clone.
What remains to do are:
- Add UI to "git fetch" to retry
- Make "git clone" use "git fetch --resume" to get the pack
[1] Quote from https://lwn.net/Articles/674392/ "she noted that Git
still does not support interrupting and resuming download operations,
which is an important bug to fix."
Nguyễn Thái Ngọc Duy (8):
pack-objects: add --skip and --skip-hash
pack-objects: produce a stable pack when --skip is given
index-pack: add --append-pack=<path>
upload-pack: new capability to pass --skip* to pack-objects
fetch-pack.c: send "skip" line to pack-objects
fetch: add --resume-pack=<path>
index-pack: --append-pack implies --strict
one ugly test to verify basic functionality
