Tests for core subproject supportAlex Riesen Wed, 18 Apr 2007 23:55:45 +0000 (01:55 +0200)

Tests for core subproject support

The following tests available:

- create subprojects: create a directory in the superproject,
initialize a git repo in it, and try adding it in super project.
Make a commit in superproject

- check if fsck ignores the subprojects: it just should give no errors

- check if commit in a subproject detected: make a commit in
subproject, git-diff-files in superproject should detect it

- check if a changed subproject HEAD can be committed: try
"git-commit -a" in superproject. It should commit changed
HEAD of a subproject

- check if diff-index works for subproject elements: compare the index
(changed by previuos tests) with the initial commit (which created
two subprojects). Should show a change for the recently changed subproject

- check if diff-tree works for subproject elements: do the same, just use
git-diff-tree. This test is somewhat redundant, I just added it for
completeness (diff, diff-files, and diff-index are already used)

- check if git diff works for subproject elements: try to limit
the diff for the name of a subproject in superproject:
git diff HEAD^ HEAD -- subproject

- check if clone works: try a clone of superproject and compare
"git ls-files -s" output in superproject and cloned repo

- removing and adding subproject: rename test. Currently implemented
as "git-update-index --force-remove", "mv" and "git-add".

- checkout in superproject: try to checkout the initial commit

Expose subprojects as special files to "git diff" machineryLinus Torvalds Sun, 15 Apr 2007 18:14:28 +0000 (11:14 -0700)

Expose subprojects as special files to "git diff" machinery

The same way we generate diffs on symlinks as the the diff of text of the
symlink, we can generate subproject diffs (when not recursing into them!)
as the diff of the text that describes the subproject.

Of course, since what descibes a subproject is just the SHA1, that's what
we'll use. Add some pretty-printing to make it a bit more obvious what is
going on, and we're done.

So with this, we can get both raw diffs and "textual" diffs of subproject
changes:

- git diff --raw:

:160000 160000 2de597b5ad348b7db04bd10cdd38cd81cbc93ab5 0000000... M sub-A

- git diff:

diff --git a/sub-A b/sub-A
index 2de597b..e8f11a4 160000
--- a/sub-A
+++ b/sub-A
@@ -1 +1 @@
-Subproject commit 2de597b5ad348b7db04bd10cdd38cd81cbc93ab5
+Subproject commit e8f11a45c5c6b9e2fec6d136d3fb5aff75393d42

NOTE! We'll also want to have the ability to recurse into the subproject
and actually diff it recursively, but that will involve a new command line
option (I'd suggest "--subproject" and "-S", but the latter is in use by
pickaxe), and some very different code.

But regardless of ay future recursive behaviour, we need the non-recursive
version too (and it should be the default, at least in the absense of
config options, so that large superprojects don't default to something
extremely expensive).

Fix some "git ls-files -o" fallout from gitlinksLinus Torvalds Sat, 14 Apr 2007 23:22:08 +0000 (16:22 -0700)

Fix some "git ls-files -o" fallout from gitlinks

Since "git ls-files" doesn't really pass down any details on what it
really wants done to the directory walking code, the directory walking
code doesn't really know whether the caller wants to know about gitlink
directories, or whether it wants to just know about ignored files.

So the directory walking code will return those gitlink directories unless
the caller has explicitly told it not to ("dir->show_other_directories"
tells the directory walker to only show "other" directories).

This kind of confuses "git ls-files -o", because
- it didn't really expect to see entries listed that were already in the
index, unless they were unmerged, and would die on that unexpected
setup, rather than just "continue".
- it didn't know how to match directory entries with the final "/"

This trivial change updates the "show_other_files()" function to handle
both of these issues gracefully. There really was no reason to die, when
the obviously correct thing for the function was to just ignore files it
already knew about (that's what "other" means here!).

Replace a pair of patches with updated ones for subproj... Junio C Hamano Sat, 14 Apr 2007 10:21:56 +0000 (03:21 -0700)

Replace a pair of patches with updated ones for subproject support.

This series of three patches is a *replacement* for the patch series of
two patches (plus one-liner fixup) I sent yesterday.

It fixes the issue I noted with "git status" incorrectly
claiming that a non-checked out subproject wasn't clean - that
was just a total thinko in the code (we were checking the
filesystem mode against S_IFDIRLNK, which obviously cannot work,
since S_IFDIRLINK is a git-internal state, not a filesystem
state).

It then re-sends the two patches on top of that, with the fix
for checking out superprojects (we should *not* mess up any
existing subproject directories, certainly not remove them - if
we already have a directory in the place where we now want a
subproject, we should leave it well alone!)

The first one really is a fix, and it makes the commit
commentary about a remaining bug in the patch I sent out
yesterday go away.

Fix gitlink index entry filesystem matchingLinus Torvalds Fri, 13 Apr 2007 16:24:13 +0000 (09:24 -0700)

Fix gitlink index entry filesystem matching

The code to match up index entries with the filesystem was stupidly
broken. We shouldn't compare the filesystem stat() information with
S_IFDIRLNK, since that's purely a git-internal value, and not what the
filesystem uses (on the filesystem, it's just a regular directory).

Also, don't bother to make the stat() time comparisons etc for DIRLNK
entries in ce_match_stat_basic(), since we do an exact match for these
things, and the hints in the stat data simply doesn't matter.

This fixes "git status" with submodules that haven't been checked out in
the supermodule.

Teach "git-read-tree -u" to check out submodules as a directory

This actually allows us to check out a supermodule after cloning, although
the submodules will obviously not be checked out, and will just be an
empty subdirectory.

[ Side note: this also shows that we currently don't correctly handle
such subprojects that aren't checked out correctly yet. They should
always show up as not being modified, but failing to resolve the
gitlink HEAD does not properly trigger the "not modified" logic in all
places it needs to..

So more work to be done, but that's a separate issue, unrelated to
the action of checking out the superproject. ]

The bulk of this patch is simply because we need to check the type of the
index entry *before* we try to read the object it points to, and that
meant that the code needed some re-organization. So I moved some of the
code in common to both symlinks and files to be a trivial helper function.

Teach git-update-index about gitlinksLinus Torvalds Thu, 12 Apr 2007 19:29:40 +0000 (12:29 -0700)

Teach git-update-index about gitlinks

I finally got around to looking at Alex' patch to teach update-index about
gitlinks too, so that "git commit -a" along with any other explicit
update-index scripts can work.

I don't think there was anything wrong with Alex' patch, but the code he
patched I felt was just so ugly that the added cases just pushed it over
the edge. Especially as I don't think that patch necessarily did the right
thing for a gitlink entry that already existed in the index, but that
wasn't actually a real git repository in the working tree (just an empty
subdirectory or a non-git snapshot because it hadn't wanted to track that
particular subproject).

So I ended up deciding to clean up the git-update-index handling the same
way I tackled the directory traversal used by git-add earlier: by
splitting the different cases up into multiple smaller functions, and just
making the code easier to read (and adding more comments about the
different cases).

So this replaces the old "process_file()" with a new "process_path()"
function that then just calls out to different helper functions depending
on what kind of path it is. Processing a nondirectory ends up being just
one of the simpler cases.

Teach directory traversal about subprojectsLinus Torvalds Wed, 11 Apr 2007 21:49:44 +0000 (14:49 -0700)

Teach directory traversal about subprojects

This is the promised cleaned-up version of teaching directory traversal
(ie the "read_directory()" logic) about subprojects. That makes "git add"
understand to add/update subprojects.

It now knows to look at the index file to see if a directory is marked as
a subproject, and use that as information as whether it should be recursed
into or not.

It also generally cleans up the handling of directory entries when
traversing the working tree, by splitting up the decision-making process
into small functions of their own, and adding a fair number of comments.

Finally, it teaches "add_file_to_cache()" that directory names can have
slashes at the end, since the directory traversal adds them to make the
difference between a file and a directory clear (it always did that, but
my previous too-ugly-to-apply subproject patch had a totally different
path for subproject directories and avoided the slash for that case).

Fix thinko in subproject entry sortingLinus Torvalds Wed, 11 Apr 2007 21:39:12 +0000 (14:39 -0700)

Fix thinko in subproject entry sorting

This fixes a total thinko in my original series: subprojects do *not* sort
like directories, because the index is sorted purely by full pathname, and
since a subproject shows up in the index as a normal NUL-terminated
string, it never has the issues with sorting with the '/' at the end.

So if you have a subproject "proj" and a file "proj.c", the subproject
sorts alphabetically before the file in the index (and must thus also sort
that way in a tree object, since trees sort as the index).

In contrast, it you have two files "proj/file" and "proj.c", the "proj.c"
will sort alphabetically before "proj/file" in the index. The index
itself, of course, does not actually contain an entry "proj/", but in the
*tree* that gets written out, the tree entry "proj" will sort after the
file entry "proj.c", which is the only real magic sorting rule.

In other words: the magic sorting rule only affects tree entries, and
*only* affects tree entries that point to other trees (ie are of the type
S_IFDIR).

Anyway, that thinko just means that we should remove the special case to
make S_ISDIRLNK entries sort like S_ISDIR entries. They don't. They sort
like normal files.

much less in the current git repository (they are totally independent

A new merge stragety 'subtree'.Junio C Hamano Fri, 16 Feb 2007 00:32:45 +0000 (16:32 -0800)

A new merge stragety 'subtree'.

This merge strategy largely piggy-backs on git-merge-recursive.
When merging trees A and B, if B corresponds to a subtree of A,
B is first adjusted to match the tree structure of A, instead of
reading the trees at the same level. This adjustment is also
done to the common ancestor tree.

If you are pulling updates from git-gui repository into git.git
repository, the root level of the former corresponds to git-gui/
subdirectory of the latter. The tree object of git-gui's toplevel
is wrapped in a fake tree object, whose sole entry has name 'git-gui'
and records object name of the true tree, before being used by
the 3-way merge code.

If you are merging the other way, only the git-gui/ subtree of
git.git is extracted and merged into git-gui's toplevel.

The detection of corresponding subtree is done by comparing the
pathnames and types in the toplevel of the tree.

Heuristics galore! That's the git way ;-).

git-bisect: allow bisecting with only one bad commit.Junio C Hamano Fri, 6 Apr 2007 06:27:44 +0000 (23:27 -0700)

git-bisect: allow bisecting with only one bad commit.

This allows you to say:

git bisect start
git bisect bad $bad
git bisect next

to start bisection without knowing a good commit. This would
have you try a commit that is half-way since the beginning of
the history, which is rather wasteful if you already know a good
commit, but if you don't (or your history is short enough that
you do not care), there is no reason not to allow this.

Bisect: teach "bisect start" to optionally use one bad and many good revs.

One bad commit is fundamentally needed for bisect to run,
and if we beforehand know more good commits, we can narrow
the bisect space down without doing the whole tree checkout
every time we give good commits.

This patch implements:

git bisect start [<bad> [<good>...]] [--] [<pathspec>...]

as a short-hand for this command sequence:

git bisect start
git bisect bad $bad
git bisect good $good1 $good2...

On the other hand, there may be some confusion between revs
(<bad> and <good>...) and <pathspec>... if -- is not used
and if an invalid rev or a pathspec that looks like a rev is
given.

Show binary file size change in diff --statAndy Parkins Wed, 4 Apr 2007 13:14:14 +0000 (13:14 +0000)

Show binary file size change in diff --stat

Previously, a binary file in the diffstat would show as:

some-binary-file.bin | Bin

The space after the "Bin" was never used. This patch changes binary
lines in the diffstat to be:

some-binary-file.bin | Bin 12345 -> 123456 bytes

The very nice "->" notation was suggested by Johannes Schindelin, and
shows the before and after sizes more clearly than "+" and "-" would.
If a size is 0 it's not shown (although it would probably be better to
treat no-file differently from zero-byte-file).

The user can see what changed in the binary file, and how big the new
file is. This is in keeping with the information in the rest of the
diffstat.

The diffstat_t members "added" and "deleted" were unused when the file
was binary, so this patch loads them with the file sizes in
builtin_diffstat(). These figures are then read in show_stats() when
the file is marked binary.

Honor -p<n> when applying git diffs

If the user is trying to apply a Git generated diff file and they

has a good reason for doing this. Such as they are me, trying to
apply a patch generated in git.git for the git-gui subdirectory to
the git-gui.git repository, where there is no git-gui subdirectory
present.

Users shouldn't supply -p2 unless they mean it. But if they are
supplying it, they probably have thought about how to make this
patch apply to their working directory, and want to risk whatever
results may come from that.

Fix lost-found to show commits only referenced by reflogsShawn O. Pearce Wed, 4 Apr 2007 14:46:14 +0000 (10:46 -0400)

Fix lost-found to show commits only referenced by reflogs

Prior to 1.5.0 the git-lost-found utility was useful to locate
commits that were not referenced by any ref. These were often
amends, or resets, or tips of branches that had been deleted.
Being able to locate a 'lost' commit and recover it by creating a
new branch was a useful feature in those days.

Unfortunately 1.5.0 added the reflogs to the reachability analysis
performed by git-fsck, which means that most commits users would
consider to be lost are still reachable through a reflog. So most
(or all!) commits are reachable, and nothing gets output from
git-lost-found.

Now git-fsck can be told to ignore reflogs during its reachability
analysis, making git-lost-found useful again to locate commits
that are no longer referenced by a ref itself, but may still be
referenced by a reflog.

Fix read-tree --prefix=dir/.

The existing code is not wrong per-se, but it started scanning the index
from a location that does not match the tree being read, and wasted
cycles.

unpack-trees: get rid of *indpos parameter.Junio C Hamano Mon, 2 Apr 2007 22:06:59 +0000 (15:06 -0700)

unpack-trees: get rid of *indpos parameter.

This variable keeps track of which entry in the original index
the traversal is looking at, and belongs to the unpack_trees_options
structure along with other traversal status information.

unpack_trees.c: pass unpack_trees_options structure... Junio C Hamano Mon, 2 Apr 2007 07:06:12 +0000 (00:06 -0700)

unpack_trees.c: pass unpack_trees_options structure to keep_entry() as well.

Other decision functions, deleted_entry() and merged_entry() take one as
their parameter, and this function should. I'll be introducing a separate
index to build the result in, and am planning to pass it as the part of the
structure.

git-read-tree --index-output=<file>Junio C Hamano Sun, 1 Apr 2007 06:27:41 +0000 (23:27 -0700)

git-read-tree --index-output=<file>

This corrects the interface mistake of the previous one, and
gives a command line parameter to the only plumbing command that
currently needs it: "git-read-tree".

We can add the calls to set_alternate_index_output() to other
plumbing commands that update the index if/when needed.

_GIT_INDEX_OUTPUT: allow plumbing to output to an alter... Junio C Hamano Sun, 1 Apr 2007 06:09:02 +0000 (23:09 -0700)

_GIT_INDEX_OUTPUT: allow plumbing to output to an alternative index file.

When defined, this allows plumbing commands that update the
index (add, apply, checkout-index, merge-recursive, mv,
read-tree, rm, update-index, and write-tree) to write their
resulting index to an alternative index file while holding a
lock to the original index file. With this, git-commit that
jumps the index does not have to make an extra copy of the index
file, and more importantly, it can do the update while holding
the lock on the index.

However, I think the interface to let an environment variable
specify the output is a mistake, as shown in the documentation.
If a curious user has the environment variable set to something
other than the file GIT_INDEX_FILE points at, almost everything
will break. This should instead be a command line parameter to
tell these plumbing commands to write the result in the named
file, to prevent stupid mistakes.
