Re: [RFC PATCH 0/5] Sparse checkout resurrection

2009/7/28 Nguyễn Thái Ngọc Duy [off-list ref]:

Hi,

I rip most of the code from my sparse checkout series,
leaving only basic stuff. Now there is no CE_NO_CHECKOUT bit (CE_VALID
will be used), no sparse pattterns. You will need to provide a script,
namely "git-shape-workdir", to specify how you want to shape your
workdir. That's all. No porcelain, only plumbing. Need to add some
options to read-tree and checkout in order to enable/disable this, but
I haven't got that far.

The first four patches is more or less CE_VALID fixups. Real stuff is
in the last patch. Sparse patterns may return as a separate
script. Currently no idea how the porcelain UI should be. The only
thing that is probably impossible this way is "git clone
--sparse". You may need to "clone -n" first, then apply sparse
checkout later.

Comments?

I don't know the git code enough to really comment on the details yet,
but I just wanted to say that I'd love to see sparse checkout support
in git. I tried your other patch series using a config variable
instead of the "git-shape-workdir" script and I liked it (although I
didn't thoroughly test it). It shouldn't be hard to write a
git-shape-workdir script to parse a modules file to decide which files
to include/exclude (I'm hoping to do that soon).

Judging by the surprisingly large number of people commenting in the
recent git survey that they want some form of sparse/partial checkout
support (myself included), I hope something like this patch series
gets some traction.

BTW...Is there a repository I can clone from that has these changes
and possibly future enhancements? I checked
<http://repo.or.cz/w/git/pclouds.git>, but I didn't see them.
