git-archive and submodules

git-archive and submodules

[Whit Armstrong]

Is there a way to ask git-archive to archive the submodules of the
project as well?

I have a project that needs it's submoduels distributed with it.

Is anyone else using submodules in this way?

my project is: 	git://repo.or.cz/fts.git

It has a submodule: 	tslib at git://repo.or.cz/tslib.git

I create the archive by:
git archive --format=tar --prefix=fts/ HEAD | gzip > ~/fts.tar.gz

and when I go into the tslib submodule directory after expanding the
archive, it is empty.

No.

Patches welcome.  :-)
 
We've talked about supporting it, and wouldn't mind having the
tool do it for exactly the reason you mention, but thus far a
patch has not been written to implement that.

[Whit Armstrong]

as a first patch that might be a bit ambitious for me, but I will give it a try.

anyway, it's good to know that there is additional support for this behavior.

Here's a script I use at work that calls git-archive recursively for
submodules and builds a single tarball for everything. If there is
interest in having something like this in git proper I could put some
work into cleaning it up for general use. Perhaps something like this
should be integrated into git-archive directly. Comments and suggestions
are welcome.

git-archive and submodules

[Woody Gilk]

(Please note that I am not subscribed to the mailing list, so if you
want me to read your reply, it must be sent to
woody.gilk@kohanaphp.com)

I would find it hugely valuable if git-archive would support
submodules, rather than leaving empty files in the place of
submodules. Supporting submodules is critical to packaging releases
(combined with signed tags). With git-archive not support submodules,
it means that I have to manually package and sign each release, rather
than using git-tag.

This seems like it should be a fairly trivial thing to support,
possibly with the addition of a --with-submodules parameter for
git-archive to avoid backwards compatibility issues.

Thank you,

<shameless-plug> This works already today if you use git-subtree[1]
instead of submodules. </shameless-plug>

Such support was already in the pipeline before 1.6.2, see this
thread:

  http://thread.gmane.org/gmane.comp.version-control.git/107030

Lars' series is still available from the repo mentioned in one of the
messages

  git://hjemli.net/pub/git/git lh/traverse-gitlinks

but does not merge into master cleanly any more, because an earlier
version of the first commit (of now three) made it into 1.6.2.  For
your testing convenience, I rebased the other two commits on 'master'
and pushed them to

  git://repo.or.cz/git/trast.git lh/traverse-gitlinks-on-master

All conflicts were trivial, but I made a minor change: there's already
a t5001 from 8aece7f (archive test: attributes, 2009-04-18), so I
renamed it to t5002 in the tip commit.

git-archive and submodules

[André Caron]

Hi,

I've recently needed to create a source code archive as part of a
custom build target.  This repository uses submodules and I need to
include the submodlule's source code in the archives too.  However,
git-archive does not have any option to do so.

I've taken a quick look at the GMANE mailing list archives and it
seems this provoked quite a discussion in 2009 and that Lars Hjemli
even wrote a patch (in several flavors) for archive.c to include
submodule-aware processing.  The lastest source code at
`git.kernel.org` does not contain any traces of this patch (or
submodule aware logic for that matter).  The mailing list archives are
not very convenient to browse and I can't figure out what the status
on this submodule-aware git-archive idea is.  Has this idea been
completely rejected, or is it still work in progress?

In case you're wondering, I don't seem to be the only one needing to
do this.  I found at least two scripts on GitHub that implement this
logic with various levels of accuracy/completeness[1][2] and I've
hacked an icky Windows batch file version [3] for minimal Windows
support until this feature can be implemented in Git itself.  I don't
mind putting in some time into a real patch if I need to, but I'm
curious about the fact that this has been requested before, a patch
was proposed and yet this is still not merged 4 years later.

So, what's the status on a submodule-aware git-archive command?

Thanks,
André

The idea is not rejected, this would be a worthwhile addition. It has
been brought up again last May, but as far as I know it is stalled
since then:

Fwd: git-archive and submodules

[André Caron]

Hi Robert,

I've recently raised the same submodule issue with git-archive you and
Lars have in the past.

What's the status on your application of the git-archive submodule
patch?  Have you applied the changes suggested by Lens Lehmann[1]?
Your Git fork on GitHub[2] seems to have only applied Lars' patch and
an unrelated SVN glob fix...

Since you've touched this only last year, I'd like to know where you
were at and I can see if I can pick up where you left off (unless you
want to finish yourself).

Thanks,
André

Greetings

I was just wondering whether there been any progress on this topic since
last year... André ?

Cheers

Re: git-archive and submodules

[Amit Bakshi]

I wrote a simple bash script that does git-archive recursively with
submodules. It first does a full mirror clone of the repo and
submodules, so that subsequent calls are faster.

git-archive and submodules

Hi All,


are there plans to add submodules support to git-archive?

plans by whom?

Git is a project with contributors from all over the place. (different
time zones,
people motivated by different means, i.e. we have the hobbiest that
scratches their
itch, we have paid people working on Git because their employer wants
them to work on Git,
there are other people (who like to) use Git in their work environment
and hack on it
in their spare time to make it awesome.)

AFAICT there are currently not a lot of people actively working on
submodule features,
though there is some history, e.g. Jens Lehmann maintains a wiki
specialised on submodules
https://github.com/jlehmann/git-submod-enhancements/wiki
and archive is mentioned there as one of the many "Issues still to be tackled".

Maybe you want to give it a try as you need it? I'd be happy to review any
submodule related code.

How to get started:

 * git clone https://github.com/git/git
 * Read (at least skim) Documentation/SubmittingPatches)
 * Look at builtin/archive.c as a starting point (cmd_archive is called
    when you call "git archive ...")
 * That leads to archive.c:write_archive, which calls parse_archive_args
  There we'd want to add an option there for recursing into submodules.
 * See write_archive_entry (still in archive.c) that mentions S_ISGITLINK
   Somewhere there you need to add code. :)

Thanks,
Stefan
