Make zlib compression level configurable, and change... Joachim B Haga Mon, 3 Jul 2006 20:11:47 +0000 (22:11 +0200)

Make zlib compression level configurable, and change default.

With the change in default, "git add ." on kernel dir is about
twice as fast as before, with only minimal (0.5%) change in
object size. The speed difference is even more noticeable
when committing large files, which is now up to 8 times faster.

The configurability is through setting core.compression = [-1..9]
which maps to the zlib constants; -1 is the default, 0 is no
compression, and 1..9 are various speed/size tradeoffs, 9
being slowest.

autoconf: Use autoconf to write installation directories to config.mak.autogen

This is beginning of patch series introducing installation configuration
using autoconf (and no other autotools) to git. The idea is to generate
config.mak.autogen using ./configure (generated from configure.ac by running
autoconf) from config.mak.in, so one can use autoconf as an _alternative_ to
ordinary Makefile, and creating one's own config.mak. Local settings in
config.mak override generated settings in config.mak.autogen

This patch includes minimal configure.ac and config.mak.in, so one can set
installation directories using autoconf generated ./configure script
e.g. ./configure --prefix=/usr

git object hash cleanups v1.4.1Linus Torvalds Fri, 30 Jun 2006 18:20:33 +0000 (11:20 -0700)

git object hash cleanups

This IMNSHO cleans up the object hashing.

The hash expansion is separated out into a function of its own, the hash
array (and size) names are made more obvious, and the code is generally
made to look a bit more like the object-ref hashing.

It also gets rid of "find_object()" returning an index (or negative
position if no object is found), since that is made redundant by the
simplified object rehashing. The basic operation is now "lookup_object()"
which just returns the object itself.

There's an almost unmeasurable speed increase, but more importantly, I
think the end result is more readable.

revision.c: --full-history fix.Linus Torvalds Sat, 1 Jul 2006 03:21:59 +0000 (20:21 -0700)

revision.c: --full-history fix.

With history simplification, we still show merges that are required
to make the history _complete_, i.e. say that you had:

a
|
b
/ \
c d
| |

and neither "a" nor "b" actually changed the file, but both "c" and "d"
did: in this case we have to leave "b" around just because otherwise there
would be no way to show the _relationship_, even if "b" itself doesn't
actually change the tree in any way what-so-ever.

It would make sense to make that further simplification if the
"--parents" flag wasn't present. In that case the user is
literally asking for a list of commits and is not interested in
the relationship between them.

This patch also fixes a real bug. Without this patch, the
"--parents --full-history" combination (which you'd get if you
do something like

gitk --full-history Makefile

or similar) will actually _drop_ merges where all children are identical.
That's wrong in the --full-history case, because it means that the graph
ends up missing lots of entries.

In the process, this also should make

git-rev-list --full-history Makefile

give just the _true_ list of all commits that changed Makefile (and
properly ignore merges that were identical in one parent), because now
we're not asking for "--parent", so we don't need the unnecessary merge
commits to keep the history together.

Improved three-way blob merging codeLinus Torvalds Thu, 29 Jun 2006 05:06:36 +0000 (22:06 -0700)

Improved three-way blob merging code

This fleshes out the code that generates a three-way merge of a set of
blobs.

It still actually does the three-way merge using an external executable
(ie just calling "merge"), but the interfaces have been cleaned up a lot
and are now fully based on the 'mmfile_t' interface, so if libxdiff were
to ever grow a compatible three-way-merge, it could probably be directly
plugged in.

It also uses the previous XDL_EMIT_COMMON functionality extension to
libxdiff to generate a made-up base file for the merge for the case where
no base file previously existed. This should be equivalent to what we
currently do in git-merge-one-file.sh:

diff -u -La/$orig -Lb/$orig $orig $src2 | git-apply --no-add

except it should be much simpler and can be done using the direct libxdiff
interfaces.

Prepare "git-merge-tree" for future workLinus Torvalds Wed, 28 Jun 2006 18:18:27 +0000 (11:18 -0700)

Prepare "git-merge-tree" for future work

This changes how "git-merge-tree" works in two ways:

- instead of printing things out as we walk the trees, we save the
results in memory.
- when we've walked the tree fully, we print out the results in a more
explicit way, describing the data.

This is basically preparatory work for extending the git-merge-tree
functionality in interesting directions.

In particular, git-merge-tree is also how you would create a diff between
two trees _without_ necessarily creating the merge commit itself. In other
words, if you were to just wonder what another branch adds, you should be
able to (eventually) just do

git merge-tree -p $base HEAD $otherbranch

to generate a diff of what the merge would look like. The current merge
tree already basically has all the smarts for this, and the explanation of
the results just means that hopefully somebody else than me could do the
boring work.

(You'd basically be able to do the above diff by just changing the
printout format for the explanation, and making the "changed in both"
first do a three-way merge before it diffs the result).

The other thing that the in-memory format allows is rename detection
(which the current code does not do). That's the basic reason why we don't
want to just explain the differences as we go along - because we want to
be able to look at the _other_ differences to see whether the reason an
entry got deleted in either branch was perhaps because it got added in
another place..

Rename detection should be a fairly trivial pass in between the tree
diffing and the explanation.

In the meantime, this doesn't actually do anything new, it just outputs
the information in a more verbose manner.

For an example merge, commit 5ab2c0a47574c92f92ea3709b23ca35d96319edd in
the git tree works well and shows renames, along with true removals and
additions and files that got changed in both branches. To see that as a
tree merge, do:

git-merge-tree 64e86c57 c5c23745 928e47e3

where the two last ones are the tips that got merged, and the first one is
the merge base.

xdiff: generate "anti-diffs" aka what is common to two files

This fairly trivial patch adds a new XDL_EMIT_xxx flag to tell libxdiff
that we don't want to generate the _diff_ between two files, we want to
see the lines that are _common_ to two files.

So when you set XDL_EMIT_COMMON, xdl_diff() will do everything exactly
like it used to do, but the output records it generates just contain the
lines that aren't part of the diff.

This is for doing things like generating the common base case for a file
that was added in both branches.

git-svn: add --follow-parent and --no-metadata options to fetch

--follow-parent:
This is especially helpful when we're tracking a directory
that has been moved around within the repository, or if we
started tracking a branch and never tracked the trunk it was
descended from.

This relies on the SVN::* libraries to work. We can't
reliably parse path info from the svn command-line client
without relying on XML, so it's better just to have the SVN::*
libs installed.

This also removes oldvalue verification when calling update-ref

In SVN, branches can be deleted, and then recreated under the
same path as the original one with different ancestry
information, causing parent information to be mismatched /
misordered.

Also force the current ref, if existing, to be a parent,
regardless of whether or not it was specified.

--no-metadata:
This gets rid of the git-svn-id: lines at the end of every commit.

With this, you lose the ability to use the rebuild command. If
you ever lose your .git/svn/git-svn/.rev_db file, you won't be
able to fetch again, either. This is fine for one-shot imports.

Also fix some issues with multi-fetch --follow-parent that were
exposed while testing this. Additionally, repack checking is
simplified greatly.

git-svn log will not work on repositories using this, either.

git-svn: SVN 1.1.x library compatibility

Tested on a plain Ubuntu Hoary installation
using subversion 1.1.1-2ubuntu3

1.1.x issues I had to deal with:

* Avoid the noisy command-line client compatibility check if we
use the libraries.

* get_log() arguments differ (now using a nice wrapper from
Junio's suggestion)

* get_file() is picky about what kind of file handles it gets,
so I ended up redirecting STDOUT. I'm probably overflushing
my file handles, but that's the safest thing to do...

* BDB kept segfaulting on me during tests, so svnadmin will use FSFS
whenever we can.

* If somebody used an expanded CVS $Id$ line inside a file, then
propsetting it to use svn:keywords will cause the original CVS
$Id$ to be retained when asked for the original file. As far as
I can see, this is a server-side issue. We won't care in the
test anymore, as long as it's not expanded by SVN, a static
CVS $Id$ line is fine.

While we're at making ourselves more compatible, avoid grep
along with the -q flag, which is GNU-specific. (grep avoidance
tip from Junio, too)
