Elsewhere in Git we already use PRIuMAX and cast to uintmax_t when
we need to display a value that is 'very big' and we're not exactly
sure what the largest display size is for this platform.
This particular fix is needed so we can do the incredibly crazy
temporary hack of:
diff --git a/cache.h b/cache.h
index e0abcd6..6637fd8 100644
--- a/cache.h
+++ b/cache.h
@@ -6,6 +6,7 @@

#if ZLIB_VERNUM < 0x1200
#define deflateBound(c,s) ((s) + (((s) + 7) >> 3) + (((s) + 63) >> 6) + 11)
allowing us to more easily look for locations where we are passing
a pointer to an 8 byte value to a function that expects a 4 byte
value. This can occur on some platforms where sizeof(long) == 8
and sizeof(size_t) == 4.

Ok, so on the kernel list, some people noticed that "git log --follow"
doesn't work too well with some files in the x86 merge, because a lot of
files got renamed in very special ways.
In particular, there was a pattern of doing single commits with renames
that looked basically like
- rename "filename.h" -> "filename_64.h"
- create new "filename.c" that includes "filename_32.h" or
"filename_64.h" depending on whether we're 32-bit or 64-bit.
which was preparatory for smushing the two trees together.
Now, there's two issues here:
- "filename.c" *remained*. Yes, it was a rename, but there was a new file
created with the old name in the same commit. This was important,
because we wanted each commit to compile properly, so that it was
bisectable, so splitting the rename into one commit and the "create
helper file" into another was *not* an option.
So we need to break associations where the contents change too much.
Fine. We have the -B flag for that. When we break things up, then the
rename detection will be able to figure out whether there are better
alternatives.
- "git log --follow" didn't with with -B.
Now, the second case was really simple: we use a different "diffopt"
structure for the rename detection than the basic one (which we use for
showing the diffs). So that second case is trivially fixed by a trivial
one-liner that just copies the break_opt values from the "real" diffopts
to the one used for rename following. So now "git log -B --follow" works
fine:
diff --git a/tree-diff.c b/tree-diff.c
index 26bdbdd..7c261fd 100644
--- a/tree-diff.c
+++ b/tree-diff.c

paths[0] = NULL;
diff_tree_setup_paths(paths, &diff_opts);
if (diff_setup_done(&diff_opts) < 0)
however, the end result does *not* work. Because our diffcore-break.c
logic is totally bogus!
In particular:
- it used to do
if (base_size < MINIMUM_BREAK_SIZE)
return 0; /* we do not break too small filepair */
which basically says "don't bother to break small files". But that
"base_size" is the *smaller* of the two sizes, which means that if some
large file was rewritten into one that just includes another file, we
would look at the (small) result, and decide that it's smaller than the
break size, so it cannot be worth it to break it up! Even if the other
side was ten times bigger and looked *nothing* like the samell file!
That's clearly bogus. I replaced "base_size" with "max_size", so that
we compare the *bigger* of the filepair with the break size.
- It calculated a "merge_score", which was the score needed to merge it
back together if nothing else wanted it. But even if it was *so*
different that we would never want to merge it back, we wouldn't
consider it a break! That makes no sense. So I added
if (*merge_score_p > break_score)
return 1;
to make it clear that if we wouldn't want to merge it at the end, it
was *definitely* a break.
- It compared the whole "extent of damage", counting all inserts and
deletes, but it based this score on the "base_size", and generated the
damage score with
delta_size = src_removed + literal_added;
damage_score = delta_size * MAX_SCORE / base_size;
but that makes no sense either, since quite often, this will result in
a number that is *bigger* than MAX_SCORE! Why? Because base_size is
(again) the smaller of the two files we compare, and when you start out
from a small file and add a lot (or start out from a large file and
remove a lot), the base_size is going to be much smaller than the
damage!
Again, the fix was to replace "base_size" with "max_size", at which
point the damage actually becomes a sane percentage of the whole.
With these changes in place, not only does "git log -B --follow" work for
the case that triggered this in the first place, ie now
git log -B --follow arch/x86/kernel/vmlinux_64.lds.S
actually gives reasonable results. But I also wanted to verify it in
general, by doing a full-history
git log --stat -B -C
on my kernel tree with the old code and the new code.
There's some tweaking to be done, but generally, the new code generates
much better results wrt breaking up files (and then finding better rename
candidates). Here's a few examples of the "--stat" output:
- This:

Now, in some other cases, it does actually turn a rename into a real
"delete+create" pair, and then the diff is usually bigger, so truth in
advertizing: it doesn't always generate a nicer diff. But for what -B was
meant for, I think this is a big improvement, and I suspect those cases
where it generates a bigger diff are tweakable.
So I think this diff fixes a real bug, but we might still want to tweak
the default values and perhaps the exact rules for when a break happens.

That happened in the case of a pathname that was ignored, and we did
not ask for "dir->show_ignored". That test used to be *together*
with the "DTYPE(de) != DT_DIR", but splitting the two tests up
means that we can do that (common) test before we even bother to
calculate the real dtype.
Of course, that optimization only matters for systems that don't
have, or don't fill in DTYPE properly.
I also clarified the real relationship between "exclude" and
"dir->show_ignored". It used to do
if (exclude != dir->show_ignored) {
..
which wasn't exactly obvious, because it triggers for two different
cases:
- the path is marked excluded, but we are not interested in ignored
files: ignore it
- the path is *not* excluded, but we *are* interested in ignored
files: ignore it unless it's a directory, in which case we might
have ignored files inside the directory and need to recurse
into it).
so this splits them into those two cases, since the first case
doesn't even care about the type.
I also made a the DT_UNKNOWN case a separate helper function,
and added some commentary to the cases.

This fixes the error reported by Michele Ballabio, where gitk will
throw a Tcl error "can't unset prevlines(...)" when displaying a
commit that has a parent commit listed more than once, and the commit
is the first child of that parent.
The problem was basically that we had two variables, prevlines and
lineends, and were relying on the invariant that prevlines($id) was
set iff $id was in the lineends($r) list for some $r. But having
a duplicate parent breaks that invariant since we end up with the
parent listed twice in lineends.
This fixes it by simplifying the logic to use only a single variable,
lineend. It also rearranges things a little so that we don't try to
draw the line for the duplicated parent twice.

There is already logic in the git wrapper to deduce the exec_path from

"../../hello/world" into an absolute path, and use that.

The current git-p4 implementation does support file renames. However, because
it does not use the "p4 integrate" command, the history for the renamed file is
not linked to the new file.
This changeset adds support for perforce renames with the integrate command.
Currently this feature is only enabled when calling git-p4 submit with the -M
option. This is intended to look and behave similar to the "detect renames"
feature of other git commands.
The following sequence is used for renamed files:
p4 integrate -Dt x x'
p4 edit x'
rm x'
git apply
p4 delete x
By default, perforce will not allow an integration with a target file that has
been deleted. That is, if x' in the example above is the name of a previously
deleted file then perforce will fail the integrate. The -Dt option tells
perforce to allow the target of integrate to be a previously deleted file.

not doing that update if the HEAD before the cherry-pick was a

A file copy would be detected only if the original file was modified in the
same commit. This implies that there will be a patch listed under the
original file name, and we would expect that clicking the original file
name in the file list warps the patch window to that file's patch. (If the
original file was not modified, the copy would not be detected in the first
place, the copied file would be listed as "new file", and this whole matter
would not apply.)
However, if the name of the copy is sorted after the original file's patch,
then the logic introduced by commit d1cb298b0b (which picks up the link
information from the "copy from" line) would overwrite the link
information that is already present for the original file name, which was
parsed earlier. Hence, this patch reverts part of said commit.

Ok, what is going on is:
- append_fetch_head() looks up the SHA1 for all heads (including tags):
if (get_sha1(head, sha1))
return error("Not a valid object name: %s", head);
- it then wants to check if it's a candidate for merging (because
fetching also does the whole "list which heads to merge" in case
it is going to be part of a "pull"):
commit = lookup_commit_reference(sha1);
if (!commit)
not_for_merge = 1;
- and that "lookup_commit_reference()" is just very vocal about the
case where it fails. It really shouldn't be, and it shouldn't
affect the actual end result, but that basically explains why
you get that scary warning.
In short, the warning is just bogus, and should be harmless, but
I agree that it's ugly. I think the appended patch should fix it.

If we are in the middle of resolving a merge conflict there may be
one or more files whose entries in the index represent an unmerged
state (index entries in the higher-order stages).
Attempting to run git-blame on any file in such a working directory
resulted in "fatal: internal error: ce_mode is 0" as we use the magic
marker for an unmerged entry is 0 (set up by things like diff-lib.c's
do_diff_cache() and builtin-read-tree.c's read_tree_unmerged())
and the ce_match_stat_basic() function gets upset about this.
I'm not entirely sure that the whole "ce_mode = 0" case is a good
idea to begin with, and maybe the right thing to do is to remove
that horrid freakish special case, but removing the internal error
seems to be the simplest fix for now.
