15 years agogit-clone: fix handling of upsteram whose HEAD does not point at master.
Junio C Hamano [Sun, 2 Apr 2006 23:25:01 +0000 (16:25 -0700)]
git-clone: fix handling of upsteram whose HEAD does not point at 

When cloning from a remote repository that has master, main, and
origin branches _and_ with the HEAD pointing at main branch, we
did quite confused things during clone.  So this cleans things
up.  The behaviour is a bit different between separate remotes/
layout and the mixed branches layout.

The newer layout with $GIT_DIR/refs/remotes/$origin/, things are
simpler and more transparent:

 - remote branches are copied to refs/remotes/$origin/.

 - HEAD points at the branch with the same name as the remote
   HEAD points at, and starts at where the remote HEAD points at.

 - $GIT_DIR/remotes/$origin file is set up to fetch all remote
   branches, and merge the branch HEAD pointed at at the time of
   the cloning.

Everything-in-refs/heads layout was the more confused one, but
cleaned up like this:

 - remote branches are copied to refs/heads, but the branch
   "$origin" is not copied, instead a copy of the branch the
   remote HEAD points at is created there.

 - HEAD points at the branch with the same name as the remote
   HEAD points at, and starts at where the remote HEAD points at.

 - $GIT_DIR/remotes/$origin file is set up to fetch all remote
   branches except "$origin", and merge the branch HEAD pointed
   at at the time of the cloning.

With this, the remote has master, main and origin, and its HEAD
points at main, you could:

git clone $URL --origin upstream

to use refs/heads/upstream as the tracking branch for remote
"main", and your primary working branch will also be "main".
"master" and "origin" are used to track the corresponding remote
branches and with this setup they do not have any special meaning.

Linus Torvalds [Fri, 31 Mar 2006 01:05:25 +0000 (17:05 -0800)]
Make path-limiting be incremental when possible.

This makes git-rev-list able to do path-limiting without having to parse
all of history before it starts showing the results.

This makes things like "git log -- pathname" much more pleasant to use.

This is actually a pretty small patch, and the biggest part of it is
purely cleanups (turning the "goto next" statements into "continue"), but
it's conceptually a lot bigger than it looks.

What it does is that if you do a path-limited revision list, and you do
_not_ ask for pseudo-parenthood information, it won't do all the
path-limiting up-front, but instead do it incrementally in
"get_revision()".

This is an absolutely huge deal for anything like "git log -- <pathname>",
but also for some things that we don't do yet - like the "find where
things changed" logic I've described elsewhere, where we want to find the
previous revision that changed a file.

The reason I put "RFC" in the subject line is that while I've validated it
various ways, like doing

git-rev-list HEAD -- drivers/char/ | md5sum

before-and-after on the kernel archive, it's "git-rev-list" after all. In
other words, it's that really really subtle and complex central piece of
software. So while I think this is important and should go in asap, I also
think it should get lots of testing and eyeballs looking at the code.

Btw, don't even bother testing this with the git archive. git itself is so
small that parsing the whole revision history for it takes about a second
even with path limiting. The thing that _really_ shows this off is doing

git log drivers/

on the kernel archive, or even better, on the _historic_ kernel archive.

With this change, the response is instantaneous (although seeking to the
end of the result will obviously take as long as it ever did). Before this
change, the command would think about the result for tens of seconds - or
even minutes, in the case of the bigger old kernel archive - before
starting to output the results.

NOTE NOTE NOTE! Using path limiting with things like "gitk", which uses
the "--parents" flag to actually generate a pseudo-history of the
resulting commits won't actually see the improvement in interactivity,
since that forces git-rev-list to do the whole-history thing after all.

MAYBE we can fix that too at some point, but I won't promise anything.

builtin_diff function passes this flag unconditionally.  I suppose it
could parse GIT_DIFF_OPTS, but it doesn't at the moment.  I've also
reintroduced the `function name' into the test suite, from which it was
removed in commit 3ce8f089.

The function names are parsed by a particularly stupid algorithm at the
moment: it just tries to find a line in the `old' file, from before the
start of the hunk, whose first character looks plausible.  Still, it's
most definitely a start.

Use a *real* built-in diff generator

This uses a simplified libxdiff setup to generate unified diffs _without_
doing  fork/execve of GNU "diff".

This has several huge advantages, for example:

Before:

[torvalds@g5 linux]$ time git diff v2.6.16.. > /dev/null

real    0m24.818s
user    0m13.332s
sys     0m8.664s

After:

[torvalds@g5 linux]$ time git diff v2.6.16.. > /dev/null

real    0m4.563s
user    0m2.944s
sys     0m1.580s

and the fact that this should be a lot more portable (ie we can ignore all
the issues with doing fork/execve under Windows).

Perhaps even more importantly, this allows us to do diffs without actually
ever writing out the git file contents to a temporary file (and without
any of the shell quoting issues on filenames etc etc).

NOTE! THIS PATCH DOES NOT DO THAT OPTIMIZATION YET! I was lazy, and the
current "diff-core" code actually will always write the temp-files,
because it used to be something that you simply had to do. So this current
one actually writes a temp-file like before, and then reads it into memory
again just to do the diff. Stupid.

But if this basic infrastructure is accepted, we can start switching over
diff-core to not write temp-files, which should speed things up even
further, especially when doing big tree-to-tree diffs.

Now, in the interest of full disclosure, I should also point out a few
downsides:

 - the libxdiff algorithm is different, and I bet GNU diff has gotten a
   lot more testing. And the thing is, generating a diff is not an exact
   science - you can get two different diffs (and you will), and they can
   both be perfectly valid. So it's not possible to "validate" the
   libxdiff output by just comparing it against GNU diff.

 - GNU diff does some nice eye-candy, like trying to figure out what the
   last function was, and adding that information to the "@@ .." line.
   libxdiff doesn't do that.

 - The libxdiff thing has some known deficiencies. In particular, it gets
   the "\No newline at end of file" case wrong. So this is currently for
   the experimental branch only. I hope Davide will help fix it.

That said, I think the huge performance advantage, and the fact that it
integrates better is definitely worth it. But it should go into a
development branch at least due to the missing newline issue.

Technical note: this is based on libxdiff-0.17, but I did some surgery to
get rid of the extraneous fat - stuff that git doesn't need, and seriously
cutting down on mmfile_t, which had much more capabilities than the diff
algorithm either needed or used. In this version, "mmfile_t" is just a
trivial <pointer,length> tuple.

That said, I tried to keep the differences to simple removals, so that you
can do a diff between this and the libxdiff origin, and you'll basically
see just things getting deleted. Even the mmfile_t simplifications are
left in a state where the diffs should be readable.

Apologies to Davide, whom I'd love to get feedback on this all from (I
wrote my own "fill_mmfile()" for the new simpler mmfile_t format: the old
complex format had a helper function for that, but I did my surgery with
the goal in mind that eventually we _should_ just do

mmfile_t mf;

buf = read_sha1_file(sha1, type, &size);
mf->ptr = buf;
mf->size = size;
.. use "mf" directly ..

which was really a nightmare with the old "helpful" mmfile_t, and really
is that easy with the new cut-down interfaces).

[ Btw, as any hawk-eye can see from the diff, this was actually generated
  with itself, so it is "self-hosting". That's about all the testing it
  has gotten, along with the above kernel diff, which eye-balls correctly,
  but shows the newline issue when you double-check it with "git-apply" ]

... and use it initially to write global extended header records.
Improvements compared to the old write_header():

  - Uses a struct ustar_header instead of hardcoded offsets.
  - Takes one struct strbuf as path argument instead of a (basedir,
    prefix, name) tuple.
  - Not only writes the tar header, but also the contents of the
    file, if any.
  - Does not write directly into the ring buffer.  This allows the
    code to be layed out more naturally, because there is no more
    ordering constraint.  Before we had to first finish writing the
    extended header, now we can construct the extended and normal
    headers in parallel.
  - The typeflag parameter has been replaced by (reasonable) magic
    values.  path == NULL indicates an extended header, additionally
    sha1 == NULL means it is a global extended header.

git-apply: safety fixes

This was triggered by me testing the "@@" numbering shorthand by GNU
patch, which not only showed that git-apply thought it meant the number
was duplicated (when it means that the second number is 1), but my tests
showed than when git-apply mis-understood the number, it would then not
raise an alarm about it if the patch ended early.

Now, this doesn't actually _matter_, since with a three-line context, the
only case that "x,1" will be shorthanded to "x" is when x itself is 1 (in
which case git-apply got it right), but the fact that git-apply would also
silently accept truncated patches was a missed opportunity for additional
sanity-checking.

So make git-apply refuse to look at a patch fragment that ends early.
