[PATCH] Diffcore updates.Junio C Hamano Sun, 22 May 2005 17:04:37 +0000 (10:04 -0700)

[PATCH] Diffcore updates.

This moves the path selection logic from individual programs to a new
diffcore transformer (diff-tree still needs to have its own for
performance reasons). Also the header printing code in diff-tree was
tweaked not to produce anything when pickaxe is in effect and there is
nothing interesting to report. An interesting example is the following
in the GIT archive itself:

[PATCH] The diff-raw format updates.

Update the diff-raw format as Linus and I discussed, except that
it does not use sequence of underscore '_' letters to express
nonexistence. All '0' mode is used for that purpose instead.

The new diff-raw format can express rename/copy, and the earlier
restriction that -M and -C _must_ be used with the patch format
output is no longer necessary. The patch makes -M and -C flags
independent of -p flag, so you need to say git-whatchanged -M -p
to get the diff/patch format.

The heuristics so far was to compare file size change and xdelta

It also makes a very small performance fix. I didn't measure

while scanning an already sorted list, breaking out in the

This patch extends diff-cache and diff-files to report the
unmodified files to diff-core as well when -C (copy detection)

the source candidates. The existing test t4003 has been

[PATCH] Introducing software archaeologist's tool ... Junio C Hamano Sat, 21 May 2005 09:40:01 +0000 (02:40 -0700)

[PATCH] Introducing software archaeologist's tool "pickaxe".

This steals the "pickaxe" feature from JIT and make it available
to the bare Plumbing layer. From the command line, the user
gives a string he is intersted in.

Using the diff-core infrastructure previously introduced, it
filters the differences to limit the output only to the diffs
between <src> and <dst> where the string appears only in one but
not in the other. For example:

$ ./git-rev-list HEAD | ./git-diff-tree -Sdiff-tree-helper --stdin -M

would show the diffs that touch the string "diff-tree-helper".

In real software-archaeologist application, you would typically
look for a few to several lines of code and see where that code
came from.

The "pickaxe" module runs after "rename/copy detection" module,
so it even crosses the file rename boundary, as the above
example demonstrates.

[PATCH] Diff overhaul, adding half of copy detection.Junio C Hamano Sat, 21 May 2005 09:39:09 +0000 (02:39 -0700)

[PATCH] Diff overhaul, adding half of copy detection.

This introduces the diff-core, the layer between the diff-tree
family and the external diff interface engine. The calls to the
interface diff-tree family uses (diff_change and diff_addremove)
have not changed and will not change. The purpose of the
diff-core layer is to provide an infrastructure to transform the
set of differences sent from the applications, before sending
them to the external diff interface.

The recently introduced rename detection code has been rewritten
to use the diff-core facility. When applications send in
separate creates and deletes, matching ones are transformed into
a single rename-and-edit diff, and sent out to the external diff
interface as such.

This patch also enhances the rename detection code further to be
able to detect copies. Currently this happens only as long as
copy sources appear as part of the modified files, but there
already is enough provision for callers to report unmodified
files to diff-core, so that they can be also used as copy source
candidates. Extending the callers this way will be done in a
separate patch.

Please see and marvel at how well this works by trying out the
newly added t/t4003-diff-rename-1.sh test script.

[PATCH] delta read

This makes the core code aware of delta objects and undeltafy them as
needed. The convention is to use read_sha1_file() to have
undeltafication done automatically (most users do that already so this
is transparent).

If the delta object itself has to be accessed then it must be done
through map_sha1_file() and unpack_sha1_file().

In that context mktag.c has been switched to read_sha1_file() as there
is no reason to do the full map+unpack manually.

This also allowed diff-cache and diff-files to acquire -R
(reverse) option to generate diff in reverse. Users of
diff-tree can swap two trees easily so I did not add -R there.

[ Linus' note: I'll add -R to "diff-tree" too, since a "commit
diff" doesn't have another tree to switch around: the other
tree is always the parent(s) of the commit ]

Also -M<digits-as-mantissa> suggestion made by Linus has been
implemented.

[PATCH] Detect renames in diff family.

This rips out the rename detection engine from diff-helper and moves it
to the diff core, and updates the internal calling convention used by

name to diff-tree family as well as to diff-helper, I've changed the
earlier diff-helper '-r' option to '-M' (stands for Move; sorry but the
natural abbreviation 'r' for 'rename' is already taken for 'recursive').

Although I did a fair amount of test with the git-diff-tree with
existing rename commits in the core GIT repository, this should still be
considered beta (preview) release. This patch depends on the diff-delta
infrastructure just committed.

This implements almost everything I wanted to see in this series of

core, but that will be a separate cleanup patch.

[PATCH] Diff-helper update

This patch adds a framework and a stub implementation of rename
detection to diff-helper program.

The current stub code is just enough to detect pure renames in
diff-tree output and not fancier. The plan is perhaps to use
the same delta code when Nico's delta storage patch is merged
for similarity evaluation purposes.

When checkout-cache attempts to check out a non-directory where
a directory exists on the work tree, or to check out a file
under directory D when path D is a non-directory on the work
tree, the attempt fails. Before running checkout-cache, the
user can run git-ls-files with the -k (killed) option to get a
list of such paths. The tagged output format uses "K" to denote
them. This is useful for Porcelain layer to be careful when
dealing with the recently corrected behaviour of checkout-cache.

[PATCH] checkout-cache fixJunio C Hamano Thu, 12 May 2005 00:02:45 +0000 (17:02 -0700)

[PATCH] checkout-cache fix

Fix checkout-cache when existing work tree interferes with the checkout.

This is essentially the same one as the last one I sent to the
GIT list, except that the patch is rebased to the current tip of
the git-pb tree, and an unnecessary call to create_directories()
removed.

The checkout-cache command gets confused when checking out a
file in a subdirectory and the work tree has a symlink to the
subdirectory. Also it fails to check things out when there is a
non-directory in the work tree when cache expects a directory
there, and vice versa. This patch fixes the first problem by
making sure all the leading paths in the file being checked out
are indeed directories, and also fixes directory vs
non-directory conflicts when '-f' is specified by removing the
offending paths.

[patch] git: fix overflow in update-cache.cIngo Molnar Thu, 14 Apr 2005 11:18:19 +0000 (13:18 +0200)

[patch] git: fix overflow in update-cache.c

this patch fixes a 1-byte overflow in update-cache.c (probably not
exploitable). A specially crafted db object might trigger this overflow.

the bug is that normally the 'type' field is parsed by read_sha1_file(),
via:

if (sscanf(buffer, "%10s %lu", type, size) != 2)

i.e. 0-10 long strings, which take 1-11 bytes of space. Normally the
type strings are stored in char [20] arrays, but in update-cache.c that
is char [10], so a 1 byte overflow might occur.

This should not happen with a 'friendly' DB, as the longest type string
("commit") is 7 bytes long. The fix is to use the customary char [20].

(someone might want to clean those open-coded constants up with a
TYPE_LEN define, they do tend to cause problems like this. I'm not
against open-coded constants (they make code much more readable), but
for fields that get filled in from possibly hostile objects this is
playing with fire.)

hey, this might be the first true security fix for GIT? ;-)
