in the sense that "interesting" merges are shown, but not all
merges.
- When a blob matches one of the parents, we do not show a diff
for that path at all. For a merge commit, this option shows
paths with real file-level merge (aka "interesting things").
- As a concequence of the above, an "uninteresting" merge is
not shown at all. You can use '-m' in addition to '-c' to
show the commit log for such a merge, but there will be no
combined diff output.
- Unlike "gitk", the output is monochrome.
A '-' character in the nth column means the line is from the nth

from that parent's version).
A '+' character in the nth column means the line appears in the
merge result, and the nth parent does not have that line
(i.e. added by the merge itself or inherited from another
parent).
The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"
line), and "unsigned char sha1[20]", prefixed by a " +", was
inherited from the first parent.
The code as sent to the list was buggy in few corner cases,
which I have fixed since then.
It does not bother to keep track of and show the line numbers
from parent commits, which it probably should.

Ok, this was nastier than expected, just because the dependencies between
the different log-printing stuff were absolutely _everywhere_, but here's
a patch that does exactly that.
The patch is not very easy to read, and the "--patch-with-stat" thing is
still broken (it does not call the "show_log()" thing properly for
merges). That's not a new bug. In the new world order it _should_ do
something like
if (rev->logopt)
show_log(rev, rev->logopt, "---\n");
but it doesn't. I haven't looked at the --with-stat logic, so I left it
alone.
That said, this patch removes more lines than it adds, and in particular,
the "cmd_log_wc()" loop is now a very clean:
while ((commit = get_revision(rev)) != NULL) {
log_tree_commit(rev, commit);
free(commit->buffer);
commit->buffer = NULL;
}
so it doesn't get much prettier than this. All the complexity is entirely
hidden in log-tree.c, and any code that needs to flush the log literally
just needs to do the "if (rev->logopt) show_log(...)" incantation.
I had to make the combined_diff() logic take a "struct rev_info" instead
of just a "struct diff_options", but that part is pretty clean.
This does change "git whatchanged" from using "diff-tree" as the commit
descriptor to "commit", and I changed one of the tests to reflect that new
reality. Otherwise everything still passes, and my other tests look fine
too.

show the commit log for such a merge, but there will be no
combined diff output.
- Unlike "gitk", the output is monochrome.
A '-' character in the nth column means the line is from the nth
parent and does not appear in the merge result (i.e. removed
from that parent's version).
A '+' character in the nth column means the line appears in the
merge result, and the nth parent does not have that line
(i.e. added by the merge itself or inherited from another
parent).
The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"
line), and "unsigned char sha1[20]", prefixed by a " +", was
inherited from the first parent.
The code as sent to the list was buggy in few corner cases,
which I have fixed since then.
It does not bother to keep track of and show the line numbers
from parent commits, which it probably should.

diff-tree -c: show a merge commit a bit more sensibly.
A new option '-c' to diff-tree changes the way a merge commit is

diff-tree -c: show a merge commit a bit more sensibly.
A new option '-c' to diff-tree changes the way a merge commit is
displayed when generating a patch output. It shows a "combined
diff" (hence the option letter 'c'), which looks like this:
$ git-diff-tree --pretty -c -p fec9ebf1 | head -n 18

{

There are a few things to note about this feature:
- The '-c' option implies '-p'. It also implies '-m' halfway
in the sense that "interesting" merges are shown, but not all
merges.
- When a blob matches one of the parents, we do not show a diff
for that path at all. For a merge commit, this option shows
paths with real file-level merge (aka "interesting things").
- As a concequence of the above, an "uninteresting" merge is
not shown at all. You can use '-m' in addition to '-c' to
show the commit log for such a merge, but there will be no
combined diff output.
- Unlike "gitk", the output is monochrome.
A '-' character in the nth column means the line is from the nth
parent and does not appear in the merge result (i.e. removed
from that parent's version).
A '+' character in the nth column means the line appears in the
merge result, and the nth parent does not have that line
(i.e. added by the merge itself or inherited from another
parent).
The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"
line), and "unsigned char sha1[20]", prefixed by a " +", was
inherited from the first parent.
The code as sent to the list was buggy in few corner cases,
which I have fixed since then.
It does not bother to keep track of and show the line numbers
from parent commits, which it probably should.

diff-tree -c: show a merge commit a bit more sensibly.
A new option '-c' to diff-tree changes the way a merge commit is

There are a few things to note about this feature:
- The '-c' option implies '-p'. It also implies '-m' halfway
in the sense that "interesting" merges are shown, but not all
merges.
- When a blob matches one of the parents, we do not show a diff
for that path at all. For a merge commit, this option shows
paths with real file-level merge (aka "interesting things").
- As a concequence of the above, an "uninteresting" merge is
not shown at all. You can use '-m' in addition to '-c' to
show the commit log for such a merge, but there will be no
combined diff output.
- Unlike "gitk", the output is monochrome.
A '-' character in the nth column means the line is from the nth
parent and does not appear in the merge result (i.e. removed
from that parent's version).
A '+' character in the nth column means the line appears in the
merge result, and the nth parent does not have that line
(i.e. added by the merge itself or inherited from another
parent).
The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"
line), and "unsigned char sha1[20]", prefixed by a " +", was
inherited from the first parent.
The code as sent to the list was buggy in few corner cases,
which I have fixed since then.
It does not bother to keep track of and show the line numbers
from parent commits, which it probably should.

The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"

inherited from the first parent.
The code as sent to the list was buggy in few corner cases,

Log message printout cleanups (#2)
Here's a further patch on top of the previous one with cosmetic
improvements (no "real" code changes, just trivial updates):
- it gets the "---" before a diffstat right, including for the combined
merge case. Righ now the logic is that we always use "---" when we have
a diffstat, and an empty line otherwise. That's how I visually prefer
it, but hey, it can be tweaked later.
- I made "diff --cc/combined" add the "---/+++" header lines too. The
thing won't be mistaken for a valid diff, since the "@@" lines have too
many "@" characters (three or more), but it just makes it visually
match a real diff, which at least to me makes a big difference in
readability. Without them, it just looks very "wrong".
I guess I should have taken the filename from each individual entry
(and had one "---" file per parent), but I didn't even bother to try to
see how that works, so this was the simple thing.
With this, doing a
git log --cc --patch-with-stat
looks quite readable, I think. The only nagging issue - as far as I'm
concerned - is that diffstats for merges are pretty questionable the way
they are done now. I suspect it would be better to just have the _first_
diffstat, and always make the merge diffstat be the one for "result
against first parent".

Ok, this was nastier than expected, just because the dependencies between
the different log-printing stuff were absolutely _everywhere_, but here's
a patch that does exactly that.
The patch is not very easy to read, and the "--patch-with-stat" thing is
still broken (it does not call the "show_log()" thing properly for
merges). That's not a new bug. In the new world order it _should_ do
something like
if (rev->logopt)
show_log(rev, rev->logopt, "---\n");
but it doesn't. I haven't looked at the --with-stat logic, so I left it
alone.
That said, this patch removes more lines than it adds, and in particular,
the "cmd_log_wc()" loop is now a very clean:
while ((commit = get_revision(rev)) != NULL) {
log_tree_commit(rev, commit);
free(commit->buffer);
commit->buffer = NULL;
}
so it doesn't get much prettier than this. All the complexity is entirely
hidden in log-tree.c, and any code that needs to flush the log literally
just needs to do the "if (rev->logopt) show_log(...)" incantation.
I had to make the combined_diff() logic take a "struct rev_info" instead
of just a "struct diff_options", but that part is pretty clean.
This does change "git whatchanged" from using "diff-tree" as the commit
descriptor to "commit", and I changed one of the tests to reflect that new
reality. Otherwise everything still passes, and my other tests look fine
too.

The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"
line), and "unsigned char sha1[20]", prefixed by a " +", was
inherited from the first parent.
The code as sent to the list was buggy in few corner cases,
which I have fixed since then.
It does not bother to keep track of and show the line numbers
from parent commits, which it probably should.

diff-tree -c: show a merge commit a bit more sensibly.
A new option '-c' to diff-tree changes the way a merge commit is
displayed when generating a patch output. It shows a "combined
diff" (hence the option letter 'c'), which looks like this:
$ git-diff-tree --pretty -c -p fec9ebf1 | head -n 18
diff-tree fec9ebf... (from parents)

There are a few things to note about this feature:
- The '-c' option implies '-p'. It also implies '-m' halfway
in the sense that "interesting" merges are shown, but not all
merges.
- When a blob matches one of the parents, we do not show a diff
for that path at all. For a merge commit, this option shows
paths with real file-level merge (aka "interesting things").
- As a concequence of the above, an "uninteresting" merge is
not shown at all. You can use '-m' in addition to '-c' to
show the commit log for such a merge, but there will be no
combined diff output.
- Unlike "gitk", the output is monochrome.
A '-' character in the nth column means the line is from the nth
parent and does not appear in the merge result (i.e. removed
from that parent's version).
A '+' character in the nth column means the line appears in the
merge result, and the nth parent does not have that line
(i.e. added by the merge itself or inherited from another

Ok, this was nastier than expected, just because the dependencies between
the different log-printing stuff were absolutely _everywhere_, but here's
a patch that does exactly that.
The patch is not very easy to read, and the "--patch-with-stat" thing is
still broken (it does not call the "show_log()" thing properly for
merges). That's not a new bug. In the new world order it _should_ do
something like
if (rev->logopt)
show_log(rev, rev->logopt, "---\n");
but it doesn't. I haven't looked at the --with-stat logic, so I left it
alone.
That said, this patch removes more lines than it adds, and in particular,
the "cmd_log_wc()" loop is now a very clean:
while ((commit = get_revision(rev)) != NULL) {
log_tree_commit(rev, commit);
free(commit->buffer);
commit->buffer = NULL;
}
so it doesn't get much prettier than this. All the complexity is entirely
hidden in log-tree.c, and any code that needs to flush the log literally
just needs to do the "if (rev->logopt) show_log(...)" incantation.
I had to make the combined_diff() logic take a "struct rev_info" instead
of just a "struct diff_options", but that part is pretty clean.
This does change "git whatchanged" from using "diff-tree" as the commit
descriptor to "commit", and I changed one of the tests to reflect that new
reality. Otherwise everything still passes, and my other tests look fine
too.

Log message printout cleanups (#2)
Here's a further patch on top of the previous one with cosmetic
improvements (no "real" code changes, just trivial updates):
- it gets the "---" before a diffstat right, including for the combined
merge case. Righ now the logic is that we always use "---" when we have
a diffstat, and an empty line otherwise. That's how I visually prefer
it, but hey, it can be tweaked later.
- I made "diff --cc/combined" add the "---/+++" header lines too. The
thing won't be mistaken for a valid diff, since the "@@" lines have too
many "@" characters (three or more), but it just makes it visually
match a real diff, which at least to me makes a big difference in
readability. Without them, it just looks very "wrong".
I guess I should have taken the filename from each individual entry
(and had one "---" file per parent), but I didn't even bother to try to
see how that works, so this was the simple thing.
With this, doing a
git log --cc --patch-with-stat
looks quite readable, I think. The only nagging issue - as far as I'm
concerned - is that diffstats for merges are pretty questionable the way
they are done now. I suspect it would be better to just have the _first_
diffstat, and always make the merge diffstat be the one for "result
against first parent".

- static void describe(struct commit *cmit, int last_one)
++ static void describe(char *arg, int last_one)
{
+ unsigned char sha1[20];
+ struct commit *cmit;
There are a few things to note about this feature:
- The '-c' option implies '-p'. It also implies '-m' halfway
in the sense that "interesting" merges are shown, but not all
merges.
- When a blob matches one of the parents, we do not show a diff
for that path at all. For a merge commit, this option shows
paths with real file-level merge (aka "interesting things").
- As a concequence of the above, an "uninteresting" merge is
not shown at all. You can use '-m' in addition to '-c' to
show the commit log for such a merge, but there will be no
combined diff output.
- Unlike "gitk", the output is monochrome.
A '-' character in the nth column means the line is from the nth
parent and does not appear in the merge result (i.e. removed
from that parent's version).
A '+' character in the nth column means the line appears in the
merge result, and the nth parent does not have that line
(i.e. added by the merge itself or inherited from another
parent).
The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"
line), and "unsigned char sha1[20]", prefixed by a " +", was
inherited from the first parent.
The code as sent to the list was buggy in few corner cases,
which I have fixed since then.
It does not bother to keep track of and show the line numbers
from parent commits, which it probably should.

diff-tree -c raw output
NOTE! This makes "-c" be the default, which effectively means that merges
are never ignored any more, and "-m" is a no-op. So it changes semantics.
I would also like to make "--cc" the default if you do patches, but didn't
actually do that.
The raw output format is not wonderfully pretty, but it's distinguishable
from a "normal patch" in that a normal patch with just one parent has just
one colon at the beginning, while a multi-parent raw diff has <n> colons
for <n> parents.
So now, in the kernel, when you do
git-diff-tree cce0cac125623f9b68f25dd1350f6d616220a8dd
(to see the manual ARM merge that had a conflict in arch/arm/Kconfig), you
get

ie you see two colons (two parents), then three modes (parent modes
followed by result mode), then three sha1s (parent sha1s followed by
result sha1).
Which is pretty close to the normal raw diff output.
Cool/stupid exercise:
$ git-whatchanged | grep '^::' | cut -f2- | sort |
uniq -c | sort -n | less -S
will show which files have needed the most file-level merge conflict
resolution. Useful? Probably not. But kind of interesting.

Ok, this was nastier than expected, just because the dependencies between
the different log-printing stuff were absolutely _everywhere_, but here's
a patch that does exactly that.
The patch is not very easy to read, and the "--patch-with-stat" thing is
still broken (it does not call the "show_log()" thing properly for
merges). That's not a new bug. In the new world order it _should_ do
something like
if (rev->logopt)
show_log(rev, rev->logopt, "---\n");
but it doesn't. I haven't looked at the --with-stat logic, so I left it
alone.
That said, this patch removes more lines than it adds, and in particular,
the "cmd_log_wc()" loop is now a very clean:
while ((commit = get_revision(rev)) != NULL) {
log_tree_commit(rev, commit);
free(commit->buffer);
commit->buffer = NULL;
}
so it doesn't get much prettier than this. All the complexity is entirely
hidden in log-tree.c, and any code that needs to flush the log literally
just needs to do the "if (rev->logopt) show_log(...)" incantation.
I had to make the combined_diff() logic take a "struct rev_info" instead
of just a "struct diff_options", but that part is pretty clean.
This does change "git whatchanged" from using "diff-tree" as the commit
descriptor to "commit", and I changed one of the tests to reflect that new
reality. Otherwise everything still passes, and my other tests look fine
too.

Ok, this was nastier than expected, just because the dependencies between
the different log-printing stuff were absolutely _everywhere_, but here's
a patch that does exactly that.
The patch is not very easy to read, and the "--patch-with-stat" thing is
still broken (it does not call the "show_log()" thing properly for
merges). That's not a new bug. In the new world order it _should_ do
something like
if (rev->logopt)
show_log(rev, rev->logopt, "---\n");
but it doesn't. I haven't looked at the --with-stat logic, so I left it
alone.
That said, this patch removes more lines than it adds, and in particular,
the "cmd_log_wc()" loop is now a very clean:
while ((commit = get_revision(rev)) != NULL) {
log_tree_commit(rev, commit);
free(commit->buffer);
commit->buffer = NULL;
}
so it doesn't get much prettier than this. All the complexity is entirely
hidden in log-tree.c, and any code that needs to flush the log literally
just needs to do the "if (rev->logopt) show_log(...)" incantation.
I had to make the combined_diff() logic take a "struct rev_info" instead
of just a "struct diff_options", but that part is pretty clean.
This does change "git whatchanged" from using "diff-tree" as the commit
descriptor to "commit", and I changed one of the tests to reflect that new
reality. Otherwise everything still passes, and my other tests look fine
too.

diff-tree -c raw output
NOTE! This makes "-c" be the default, which effectively means that merges
are never ignored any more, and "-m" is a no-op. So it changes semantics.
I would also like to make "--cc" the default if you do patches, but didn't
actually do that.
The raw output format is not wonderfully pretty, but it's distinguishable
from a "normal patch" in that a normal patch with just one parent has just
one colon at the beginning, while a multi-parent raw diff has <n> colons
for <n> parents.
So now, in the kernel, when you do
git-diff-tree cce0cac125623f9b68f25dd1350f6d616220a8dd
(to see the manual ARM merge that had a conflict in arch/arm/Kconfig), you
get
cce0cac125623f9b68f25dd1350f6d616220a8dd
::100644 100644 100644 4a63a8e2e45247a11c068c6ed66c6e7aba29ddd9 77eee38762d69d3de95ae45dd9278df9b8225e2c 2f61726d2f4b636f6e66696700dbf71a59dad287 arch/arm/Kconfig
ie you see two colons (two parents), then three modes (parent modes
followed by result mode), then three sha1s (parent sha1s followed by
result sha1).
Which is pretty close to the normal raw diff output.
Cool/stupid exercise:
$ git-whatchanged | grep '^::' | cut -f2- | sort |
uniq -c | sort -n | less -S
will show which files have needed the most file-level merge conflict
resolution. Useful? Probably not. But kind of interesting.
For the kernel, it's

diff-tree -c: show a merge commit a bit more sensibly.
A new option '-c' to diff-tree changes the way a merge commit is
displayed when generating a patch output. It shows a "combined
diff" (hence the option letter 'c'), which looks like this:
$ git-diff-tree --pretty -c -p fec9ebf1 | head -n 18

There are a few things to note about this feature:
- The '-c' option implies '-p'. It also implies '-m' halfway
in the sense that "interesting" merges are shown, but not all
merges.
- When a blob matches one of the parents, we do not show a diff
for that path at all. For a merge commit, this option shows
paths with real file-level merge (aka "interesting things").
- As a concequence of the above, an "uninteresting" merge is
not shown at all. You can use '-m' in addition to '-c' to
show the commit log for such a merge, but there will be no
combined diff output.
- Unlike "gitk", the output is monochrome.
A '-' character in the nth column means the line is from the nth
parent and does not appear in the merge result (i.e. removed
from that parent's version).
A '+' character in the nth column means the line appears in the
merge result, and the nth parent does not have that line
(i.e. added by the merge itself or inherited from another
parent).
The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"
line), and "unsigned char sha1[20]", prefixed by a " +", was
inherited from the first parent.
The code as sent to the list was buggy in few corner cases,
which I have fixed since then.
It does not bother to keep track of and show the line numbers
from parent commits, which it probably should.

diff-tree -c: show a merge commit a bit more sensibly.
A new option '-c' to diff-tree changes the way a merge commit is
displayed when generating a patch output. It shows a "combined
diff" (hence the option letter 'c'), which looks like this:
$ git-diff-tree --pretty -c -p fec9ebf1 | head -n 18

There are a few things to note about this feature:
- The '-c' option implies '-p'. It also implies '-m' halfway
in the sense that "interesting" merges are shown, but not all
merges.
- When a blob matches one of the parents, we do not show a diff
for that path at all. For a merge commit, this option shows
paths with real file-level merge (aka "interesting things").
- As a concequence of the above, an "uninteresting" merge is
not shown at all. You can use '-m' in addition to '-c' to
show the commit log for such a merge, but there will be no
combined diff output.
- Unlike "gitk", the output is monochrome.
A '-' character in the nth column means the line is from the nth
parent and does not appear in the merge result (i.e. removed
from that parent's version).
A '+' character in the nth column means the line appears in the
merge result, and the nth parent does not have that line
(i.e. added by the merge itself or inherited from another
parent).
The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"
line), and "unsigned char sha1[20]", prefixed by a " +", was
inherited from the first parent.
The code as sent to the list was buggy in few corner cases,
which I have fixed since then.
It does not bother to keep track of and show the line numbers
from parent commits, which it probably should.

Log message printout cleanups (#2)
Here's a further patch on top of the previous one with cosmetic
improvements (no "real" code changes, just trivial updates):
- it gets the "---" before a diffstat right, including for the combined
merge case. Righ now the logic is that we always use "---" when we have
a diffstat, and an empty line otherwise. That's how I visually prefer
it, but hey, it can be tweaked later.
- I made "diff --cc/combined" add the "---/+++" header lines too. The
thing won't be mistaken for a valid diff, since the "@@" lines have too
many "@" characters (three or more), but it just makes it visually
match a real diff, which at least to me makes a big difference in
readability. Without them, it just looks very "wrong".
I guess I should have taken the filename from each individual entry
(and had one "---" file per parent), but I didn't even bother to try to
see how that works, so this was the simple thing.
With this, doing a
git log --cc --patch-with-stat
looks quite readable, I think. The only nagging issue - as far as I'm
concerned - is that diffstats for merges are pretty questionable the way
they are done now. I suspect it would be better to just have the _first_
diffstat, and always make the merge diffstat be the one for "result
against first parent".
