* will git provide `submodule remove` option ?
From: Lingcha X @ 2013-02-05 10:32 UTC (permalink / raw)
To: git@vger.kernel.org
As we all know, git provides `submodule add , init, update, sync, sumary, foreach, status`, but where is `submodule remove`?
will
I not delete one of them sometime in the future? Although most people
will not use submodule or one who uses it can remove submodule by hand, providing complete options may be a good idea.
I am not familiar with C, but i can help test it. will anyone finish this feature?

Sounds like a reasonable goal.

I think "git show" with blobs originally did not because we have no
filename with which to look up the attributes. IIRC, the patches to
support "cat-file --textconv" taught get_sha1_with_context to report the
path at which we found a blob. I suspect it is mostly a matter of
plumbing that information from the revision parser through to
show_blob_object.

Yeah, though I wonder if it should be on by default. The diffstat for a
binary file, unlike the diff, is already useful. The diffstat of the
textconv'd data may _also_ be useful, of course.

Is this really a new form of GREP_BINARY_*? What happens when a file
does not have a textconv filter?
I would expect this to be more like diff's "--textconv" flag, which is
really "allow textconv to be respected". Then you could do:
git grep -I --textconv foo
to grep in the text version of files which support it, and ignore the
rest.

Hmm. grep_source_load is more or less the analogue of
diff_populate_filespec, which does not know about textconv at all. So I
feel like this might be going in at the wrong layer...

The is_binary function learned about "opt" so that it could pass it to
grep_source_load, which might do the textconv for us. But we _know_ that
we will not here, because we see that we have other GREP_BINARY flags.
And when we do have _TEXTCONV:

We do not call is_binary. :)

So here we do the textconv for the sha1 case. But what about file
sources?
This is why I think the layer is wrong; you want the fill_textconv
function to call your abstract _load function (in the diff_filespec
world, it is diff_filespec_populate, but it is the moral equivalent).
And you want it to hold off as long as possible in case we can pull the
value from cache, or feed the working tree version of a file straight to
the filter.

This is wrong. The point of userdiff_get_textconv is that it will return
NULL when we are not doing textconv for this path. So you can use it
like:
struct userdiff_driver *textconv = userdiff_get_textconv(gs->driver);
if (textconv) {
/* ok, we are doing textconv. Call our fill_textconv
* equivalent. */
}
else {
/* nope, plain old file. */
}
But by assigning it on top of gs->driver, you're going to end up with a
NULL driver sometimes. And the post-condition of the load_driver
function is that gs->driver always points to a valid driver (even if it
is the default one). I wouldn't be surprised if this causes segfaults.
So I would do it more like the patch below. Only lightly tested by me.
There are some refactoring opportunities if you want to bring
grep_source and diff_filespec closer together.

I'm a bit late to this so sorry if this has been covered before.
In the initial draft of this series the rationale for it was "reducing
the network cost while talking with a repository with tons of
refs"[1]. But later you seem to have changed your mind, and "network
bandwidth reduction of advertisement is a side effect of clutter
reduction, and not necessarily the primary goal".
Do you have any plans for something that *does* have the reduction of
network bandwidth as a primary goal?
In October I asked if anyone was working on a next-gen Git protocol[3]
that would provide clients with the ability to specify what refs they
wanted. You replied to me off-list saying "Yes".
Is this what you've been working on? Because if so I misunderstood you
thinking you were going to work on something that gave clients the
ability specify what they wanted before the initial ref advertisement.
I'm still very keen to have that ability, so if you're not working on
it I just might give it a go.

I should have read your cover letter more closely, as I see you make the
point there that this is no longer about the efficiency, but about
uncluttering.
I'm not sure I like it as an uncluttering tool, though; for the reasons
I stated in my previous mail, it makes it much more awkward for the
moments when you actually do want to fetch some of the "clutter".

I don't think that is in the same class. --full-diff is quite useful for
many other diff formats. E.g.:
git log --full-diff --raw Makefile
If you are proposing to default to "-p" when "--full-diff" is used but
no format is given, that is a slightly different thing. The --full-diff
in such a case is indeed useless, but I do not think it necessarily
follows that "-p" was what the user wanted.

Repeated splits of exactly the same history are

Using this option helps to reduce log clutter. People
rarely want to see every change that happened between
v1.0 and v1.1 of the library they're using, since none of the

Using '--squash' also helps avoid problems when the same

belongs to which subtree.

Furthermore, with '--squash', you can switch back and

than strictly forward. 'git subtree merge --squash'
always adjusts the subtree to match the exactly
specified commit, even if getting to that commit would
require undoing some changes that were added earlier.

Damn. Sorry, I sent this before getting all of the feedback. Just
ignore this sequence and I'll send a fixed version in the future.

* [PATCH 13/13] contrib/subtree: Remove --annotate
From: David A. Greene @ 2013-02-05 11:36 UTC (permalink / raw)
To: git; +Cc: David A. Greene
In-Reply-To: <1360064219-28789-1-git-send-email-greened@obbligato.org>
From: "David A. Greene" <greened@obbligato.org>
Remove --annotate. This obviates the need for an --unannotate
command. We really want a more generalized commit message rewrite
mechanism.

Yeah, I just noticed a misalignment in Vietnamese translation (just
two spaces to the left, hard to notice unless paying attention).

First of all, #include "utf8.h" is required for utf8_strwidth().
The "strlen(s) - 2" is quite sensitive to how "s" is written. How
about this? A bit longer but clearer. Your version is OK too with a
comment explaining "strlen(s) - 2".

While looking at parse-options.c, I notice "-NUM" is not marked for
translation. I think you might want to mark it so that you can
translate "NUM" to a similar abbreviation in a local language. A
similar patch like this is required so we get columns for "-NUM"
translation instead of the number of bytes.

Use fputs instead. I looked up fputs man page but somehow still left
fprintf there.

Looking good. Junio, do you need a new patch mail or can you just
amend the commit message?

I don't agree that removing `--annotate` obviates the need for `--unannotate`.
I responded on 1/17 with what I think is a typical and normal use case
for that option:
- add "fancylib" as a subtree of "myprog"
- commit to "myprog" repo: "fancylib: don't crash as much"
- split these commits back out to "fancylib" main repo, and remove
the "fancylib: " prefix
In my opinion this is a pretty normal workflow. Commits to "fancylib"
in the "myprog" repo are prefixed with "fancylib: ", and that prefix
becomes redundant and should be removed if those commits are split
back out into the "fancylib" main repo.
I also tried to come up with another situation that would justify a
more general commit message rewriting facility, and I couldn't think
of any other good use cases that don't involve removing a prefix. But
that doesn't mean there aren't any.
`--unannotate` is a clunky name, but I think this functionality is
worth taking another look at. Maybe it could be called
`--remove-prefix` ?

Hmm. The parser I implemented only does single-line parsing, and I
misunderstood the format to be single-line (partly because I have never
seen anyone using the multi-line format you show). Looking at
Net::Netrc more carefully, it seems that the "machine" token is what
defines an entry, so a new entry starts with a new line that contains a
"machine" token. Is that acceptable and does it match your
understanding of the format? It matches Net::Netrc, at least.
I'll add this change to PATCHv4 with the assumption you agree.

OK, I'll review these for PATCHv4 (also see below). Thanks.

After thinking about it, I agree with Peff multiple sources make sense
and will simplify the code flow (especially the default case, which
won't need to be handled separately). And the functionality doesn't
have to be confusing with the right debugging messages. So I'll add
them in PATCHv4.
The debugging messages will be fewer and simpler with this approach,
which makes it feel like the right track :)
Thanks
Ted
