b5c698d947 git-blame --porcelain
The new option makes the command's native output format to emit
output that is easier to handle by Porcelain.

Each line is output after a header.  The header at the minimum
has the first line which has:

 - 40-byte SHA-1 of the commit the line is attributed to;

 - the line number of the line in the original file;

 - the line number of the line in the final file;

 - on a line that starts a group of line from a different commit
   than the previous one, the number of lines in this group.  On
   subsequent lines this field is absent.

This header line is followed by the following information once
for each commit:

 - author name ("author"), email ("author-mail"), time
   ("author-time"), and timezone ("author-tz"); similarly for
   committer.

 - filename in the commit the line is attributed to.

 - the first line of the commit log message ("summary").

The contents of the actual line is output after the above
header, prefixed by a TAB. This is to allow adding more header
elements later.

cf54a029ff git-blame: --show-number (and -n)
The new option makes the command's native output format show the
original line number in the blamed revision.

Note: the current implementation of find_orig_linenum involves
linear search through the line_map array every time.  It should
probably build a reverse map upfront and do a simple look-up to
speed things up, but I'll leave it to more clever and beautiful
people ;-).

9befac470b Replace uses of strdup with xstrdup.
Like xmalloc and xrealloc xstrdup dies with a useful message if
the native strdup() implementation returns NULL rather than a
valid pointer.

I just tried to use xstrdup in new code and found it to be missing.
However I expected it to be present as xmalloc and xrealloc are
already commonly used throughout the code.

[jc: removed the part that deals with last_XXX, which I am
 finding more and more dubious these days.]

e702496e43 Convert memcpy(a,b,20) to hashcpy(a,b).
This abstracts away the size of the hash values when copying them
from memory location to memory location, much as the introduction
of hashcmp abstracted away hash value comparsion.

A few call sites were using char* rather than unsigned char* so
I added the cast rather than open hashcpy to be void*.  This is a
reasonable tradeoff as most call sites already use unsigned char*
and the existing hashcmp is also declared to be unsigned char*.

[jc: Splitted the patch to "master" part, to be followed by a
 patch for merge-recursive.c which is not in "master" yet.

 Fixed the cast in the latter hunk to combine-diff.c which was
 wrong in the original.

 Also converted ones left-over in combine-diff.c, diff-lib.c and
 upload-pack.c ]

db6296a566 Call setup_git_directory() early
Any git command that expects to work in a subdirectory of a project, and
that reads the git config files (which is just about all of them) needs to
make sure that it does the "setup_git_directory()" call before it tries to
read the config file.

This means, among other things, that we need to move the call out of
"init_revisions()", and into the caller.

This does the mostly trivial conversion to do that.

a9486b02ec Avoid C99 comments, use old-style C comments instead.
This doesn't make the code uglier or harder to read, yet it makes the
code more portable.  This also simplifies checking for other potential
incompatibilities.  "gcc -std=c89 -pedantic" can flag many incompatible
constructs as warnings, but C99 comments will cause it to emit an error.

d3ff6f5501 Move "void *util" from "struct object" into "struct commit"
Every single user actually wanted this only for commit objects, and we
have no reason to waste space on it for other object types. So just move
the structure member from the low-level "struct object" into the "struct
commit".

This leaves the commit object the same size, and removes one unnecessary
pointer from all other object allocations.

This shrinks memory usage (still at a fairly hefty half-gig, admittedly)
of "git-rev-list --all --objects" on the mozilla repo by another 5% in my
tests.

88a8b79556 blame: Nicer output
As pointed out by Junio, it may be dangerous to cut off people's names
after 15 bytes. If the name is encoded in an encoding which uses more
than one byte per code point we may end up with outputting garbage.
Instead of trying to do something smart, just output the entire name.
We don't gain much screen space by chopping it off anyway.

Furthermore, only output the file name if we actually found any
renames.

The commit 604c86d15b changed the

A big mistake without proper testing.

The form "diff -u -U 0" shows the default 3-line contexts,

its longhand "diff --unified=0") is what we meant.

fc675b8cd5 git-blame, take 2
Here is an updated version of git-blame. The main changes compared to
the first version are:

* Use the new revision.h interface to do the revision walking
* Do the right thing in a lot of more cases than before. In particular
  parallel development tracks are hopefully handled sanely.
* Lots of clean-up

It still won't follow file renames though.

There are still some differences in the output between git-blame and
git-annotate. For example, in 'Makefile' git-blame assigns lines
354-358 to 455a7f3275 and git-annotate
assigns the same lines to 79a9d8ea0d.

I think git-blame is correct in this case. This patterns occur in
several other places, git-annotate seems to sometimes assign lines to
merge commits when the lines actually changed in some other commit
which precedes the merge.

[jc: I have conned Ryan into doing test cases, so that it would
help development and fixes on both implementations.  Let the
battle begin! ;-) ]

cbfb73d73f Add git-blame, a tool for assigning blame.
I have also been working on a blame program. The algorithm is pretty
much the one described by Junio in his blame.perl. My variant doesn't
handle renames, but it shouldn't be too hard to add that. The output
is minimal, just the line number followed by the commit SHA1.

An interesting observation is that the output from my git-blame and
your git-annotate doesn't match on all files in the git
repository. One example where several lines differ is read-cache.c. I
haven't investigated it further to find out which one is correct.

The code should be considered as a work in progress. It certainly has
a couple of rough edges. The output looks fairly sane on the few files
I have tested it on, but it wouldn't be too surprising if it gets some
cases wrong.

[jc: adding it to pu for wider comments. I did minimum
whitespace fixups but it still needs an indent run and
-Wdeclaration-after-statement fixups.]
