Daniel Barkalow 3ee79d9f59 Combine To: and Cc: headers
RFC 2822 only permits a single To: header and a single Cc: header, so
we need to turn multiple values of each of these into a list. This
will be particularly significant with a command-line option to add Cc:
headers, where the user can't make sure to configure valid header sets
in any easy way.

Junio C Hamano 3384a2dfc1 shortlog: default to HEAD when the standard input is a tty
Instead of warning the user that it is expecting git log output from
the standard input (and waiting for the user to type the log from
the keyboard, which is a silly thing to do), default to traverse from
HEAD when there is no rev parameter given and the standard input is
a tty.

This factors out a useful helper "add_head()" from builtin-diff.c to a
more appropriate place revision.c while renaming it to more descriptive
name add_head_to_pending(), as that is what the function is about.

Junio C Hamano 774751a8bc Re-fix "builtin-commit: fix --signoff"
An earlier fix to the said commit was incomplete; it mixed up the
meaning of the flag parameter passed to the internal fmt_ident()
function, so this corrects it.

git_author_info() and git_committer_info() can be told to issue a
warning when no usable user information is found, and optionally can be
told to error out.  Operations that actually use the information to
record a new commit or a tag will still error out, but the caller to
leave reflog record will just silently use bogus user information.

Not warning on misconfigured user information while writing a reflog
entry is somewhat debatable, but it is probably nicer to the users to
silently let it pass, because the only information you are losing is who
checked out the branch.

 * git_author_info() and git_committer_info() used to take 1 (positive
   int) to error out with a warning on misconfiguration; this is now
   signalled with a symbolic constant IDENT_ERROR_ON_NO_NAME.

 * These functions used to take -1 (negative int) to warn but continue;
   this is now signalled with a symbolic constant IDENT_WARN_ON_NO_NAME.

 * fmt_ident() function implements the above error reporting behaviour
   common to git_author_info() and git_committer_info().  A symbolic
   constant IDENT_NO_DATE can be or'ed in to the flag parameter to make
   it return only the "Name <email@address.xz>".

 * fmt_name() is a thin wrapper around fmt_ident() that always passes
   IDENT_ERROR_ON_NO_NAME and IDENT_NO_DATE.

Linus Torvalds 7dc0fe3be5 Fix parent rewriting in --early-output
We cannot tell a node that has been checked and found not to be
interesting (which does not have the TREECHANGE flag) from a
node that hasn't been checked if it is interesting or not,
without relying on something else, such as object->parsed.

But an object can get the "parsed" flag for other reasons.
Which means that "TREECHANGE" has the wrong polarity.

This changes the way how the path pruning logic marks an
uninteresting commits.  From now on, we consider a commit
interesting by default, and explicitly mark the ones we decided
to prune.  The flag is renamed to "TREESAME".

Then, this fixes the logic to show the early output with
incomplete pruning.  It basically says "a commit that has
TREESAME set is kind-of-UNINTERESTING", but obviously in a
different way than an outright UNINTERESTING commit.  Until we
parse and examine enough parents to determine if a commit
becomes surely "kind-of-UNINTERESTING", we avoid rewriting
the ancestry so that later rounds can fix things up.

Linus Torvalds 53b2c823f6 revision walker: mini clean-up
This removes the unnecessary indirection of "revs->prune_fn",
since that function is always the same one (or NULL), and there
is in fact not even an abstraction reason to make it a function
(i.e. its not called from some other file and doesn't allow us
to keep the function itself static or anything like that).

It then just replaces it with a bit that says "prune or not",
and if not pruning, every commit gets TREECHANGE.

That in turn means that

 - if (!revs->prune_fn || (flags & TREECHANGE))
 - if (revs->prune_fn && !(flags & TREECHANGE))

just become

 - if (flags & TREECHANGE)
 - if (!(flags & TREECHANGE))

respectively.

Together with adding the "single_parent()" helper function, the "complex"
conditional now becomes

	if (!(flags & TREECHANGE) && rev->dense && single_parent(commit))
		continue;

Also indirection of "revs->dense" checking is thrown away the
same way, because TREECHANGE bit is set appropriately now.

Linus Torvalds 252a7c0235 Enhance --early-output format
This makes --early-output a bit more advanced, and actually makes it
generate multiple "Final output:" headers as it updates things
asynchronously. I realize that the "Final output:" line is now illogical,
since it's not really final until it also says "done", but

It now _always_ generates a "Final output:" header in front of any commit
list, and that output header gives you a *guess* at the maximum number of
commits available. However, it should be noted that the guess can be
completely off: I do a reasonable job estimating it, but it is not meant
to be exact.

So what happens is that you may get output like this:

 - at 0.1 seconds:

	Final output: 2 incomplete
	.. 2 commits listed ..

 - half a second later:

	Final output: 33 incomplete
	.. 33 commits listed ..

 - another half a second after that:

	Final output: 71 incomplete
	.. 71 commits listed ..

 - another half second later:

	Final output: 136 incomplete
	.. 100 commits listed: we hit the --early-output limit, and
	.. will only output 100 commits, and after this you'll not
	.. see an "incomplete" report any more since you got as much
	.. early output as you asked for!

 - .. and then finally:

	Final output: 73106 done
	.. all the commits ..

The above is a real-life scenario on my current kernel tree after having
flushed all the caches.

Tested with the experimental gitk patch that Paul sent out, and by looking
at the actual log output (and verifying that my commit count guesses
actually match real life fairly well).

Linus Torvalds cdcefbc971 Add "--early-output" log flag for interactive GUI use
This adds support for "--early-output[=n]" as a flag to the "git log"
family of commands.  This allows GUI programs to state that they want to
get some output early, in order to be able to show at least something
quickly, even if the full output may take longer to generate.

If no count is specified, a default count of a hundred commits will be
used, although the actual numbr of commits output may be smaller
depending on how many commits were actually found in the first tenth of
a second (or if *everything* was found before that, in which case no
early output will be provided, and only the final list is made
available).

When the full list is generated, there will be a "Final output:" string
prepended to it, regardless of whether any early commits were shown or
not, so that the consumer can always know the difference between early
output and the final list.

Pierre Habouzit 674d172730 Rework pretty_print_commit to use strbufs instead of custom buffers.
Also remove the "len" parameter, as:
  (1) it was used as a max boundary, and every caller used ~0u
  (2) we check for final NUL no matter what, so it doesn't help for speed.

a lot less local variables, this makes the code way more readable, and
easier to extend if needed.

Junio C Hamano 8a1d076e21 "format-patch --root rev" is the way to show everything.
We used to trigger the special case "things not in origin"
semantics only when one and only one positive ref is given, and
no number (e.g. "git format-patch -4 origin") was specified, and
used the general revision range semantics for everything else.

This narrows the special case a bit more, by making:

	git format-patch --root this_version

to show everything that leads to the named commit.

More importantly, document the two different semantics better.
The generic revision range semantics came later and bolted on
without being clearly documented.

Linus Torvalds 750f7b668f Finally implement "git log --follow"
Ok, I've really held off doing this too damn long, because I'm lazy, and I
was always hoping that somebody else would do it.

But no, people keep asking for it, but nobody actually did anything, so I
decided I might as well bite the bullet, and instead of telling people
they could add a "--follow" flag to "git log" to do what they want to do,
I decided that it looks like I just have to do it for them..

The code wasn't actually that complicated, in that the diffstat for this
patch literally says "70 insertions(+), 1 deletions(-)", but I will have
to admit that in order to get to this fairly simple patch, you did have to
know and understand the internal git diff generation machinery pretty
well, and had to really be able to follow how commit generation interacts
with generating patches and generating the log.

So I suspect that while I was right that it wasn't that hard, I might have
been expecting too much of random people - this patch does seem to be
firmly in the core "Linus or Junio" territory.

To make a long story short: I'm sorry for it taking so long until I just
did it.

I'm not going to guarantee that this works for everybody, but you really
can just look at the patch, and after the appropriate appreciative noises
("Ooh, aah") over how clever I am, you can then just notice that the code
itself isn't really that complicated.

All the real new code is in the new "try_to_follow_renames()" function. It
really isn't rocket science: we notice that the pathname we were looking
at went away, so we start a full tree diff and try to see if we can
instead make that pathname be a rename or a copy from some other previous
pathname. And if we can, we just continue, except we show *that*
particular diff, and ever after we use the _previous_ pathname.

One thing to look out for: the "rename detection" is considered to be a
singular event in the _linear_ "git log" output! That's what people want
to do, but I just wanted to point out that this patch is *not* carrying
around a "commit,pathname" kind of pair and it's *not* going to be able to
notice the file coming from multiple *different* files in earlier history.

IOW, if you use "git log --follow", then you get the stupid CVS/SVN kind
of "files have single identities" kind of semantics, and git log will just
pick the identity based on the normal move/copy heuristics _as_if_ the
history could be linearized.

Put another way: I think the model is broken, but given the broken model,
I think this patch does just about as well as you can do. If you have
merges with the same "file" having different filenames over the two
branches, git will just end up picking _one_ of the pathnames at the point
where the newer one goes away. It never looks at multiple pathnames in
parallel.

And if you understood all that, you probably didn't need it explained, and
if you didn't understand the above blathering, it doesn't really mtter to
you. What matters to you is that you can now do

	git log -p --follow builtin-rev-list.c

and it will find the point where the old "rev-list.c" got renamed to
"builtin-rev-list.c" and show it as such.

Junio C Hamano 80583c0ef6 Lift 16kB limit of log message output
Traditionally we had 16kB limit when formatting log messages for
output, because it was easier to arrange for the caller to have
a reasonably big buffer and pass it down without ever worrying
about reallocating.

This changes the calling convention of pretty_print_commit() to
lift this limit.  Instead of the buffer and remaining length, it
now takes a pointer to the pointer that points at the allocated
buffer, and another pointer to the location that stores the
allocated length, and reallocates the buffer as necessary.

To support the user format, the error return of interpolate()
needed to be changed.  It used to return a bool telling "Ok the
result fits", or "Sorry, I had to truncate it".  Now it returns
0 on success, and returns the size of the buffer it wants in
order to fit the whole result.

Introduce --inline to add multipart/mixed that is inlined, and
make --attach to create an attachement.

Nicolas Pitre 21666f1aae convert object type handling from a string to a number
We currently have two parallel notation for dealing with object types
in the code: a string and a numerical value.  One of them is obviously
redundent, and the most used one requires more stack space and a bunch
of strcmp() all over the place.

This is an initial step for the removal of the version using a char array
found in object reading code paths.  The patch is unfortunately large but
there is no sane way to split it in smaller parts without breaking the
system.

Robin Rosenberg c06d2daa12 Limit filename for format-patch
Badly formatted commits may have very long comments. This causes
git-format-patch to fail. To avoid that, truncate the filename
to a value we believe will always work.

Err out if the patch file cannot be created.

Junio C Hamano cc44c7655f Mechanical conversion to use prefixcmp()
This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily.  Leftover from this will be fixed in a separate step, including
idiotic conversions like

    if (!strncmp("foo", arg, 3))

  =>

    if (!(-prefixcmp(arg, "foo")))

This was done by using this script in px.perl

   #!/usr/bin/perl -i.bak -p
   if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) {
           s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|;
   }
   if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) {
           s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|;
   }

and running:

   $ git grep -l strncmp -- '*.c' | xargs perl px.perl

Linus Torvalds cf39f54efc git reflog show
It makes "git reflog [show]" act as

	git log -g --pretty=oneline --abbrev-cmit

and is fairly straightforward. So you can just write

	git reflog

or

	git reflog show

and it will show you the reflog in a nice format.

Junio C Hamano 01754769ab Don't force everybody to call setup_ident().
Back when only handful commands that created commit and tag were
the only users of committer identity information, it made sense
to explicitly call setup_ident() to pre-fill the default value
from the gecos information.  But it is much simpler for programs
to make the call automatic when get_ident() is called these days,
since many more programs want to use the information when updating
the reflog.

Junio C Hamano cb280e1075 Allow non-developer to clone, checkout and fetch more easily.
The code that uses committer_info() in reflog can barf and die
whenever it is asked to update a ref.  And I do not think
calling ignore_missing_committer_name() upfront like recent
receive-pack did in the aplication is a reasonable workaround.

What the patch does.

 - git_committer_info() takes one parameter.  It used to be "if
   this is true, then die() if the name is not available due to
   bad GECOS, otherwise issue a warning once but leave the name
   empty".  The reason was because we wanted to prevent bad
   commits from being made by git-commit-tree (and its
   callers).  The value 0 is only used by "git var -l".

   Now it takes -1, 0 or 1.  When set to -1, it does not
   complain but uses the pw->pw_name when name is not
   available.  Existing 0 and 1 values mean the same thing as
   they used to mean before.  0 means issue warnings and leave
   it empty, 1 means barf and die.

 - ignore_missing_committer_name() and its existing caller
   (receive-pack, to set the reflog) have been removed.

 - git-format-patch, to come up with the phoney message ID when
   asked to thread, now passes -1 to git_committer_info().  This
   codepath uses only the e-mail part, ignoring the name.  It
   used to barf and die.  The other call in the same program
   when asked to add signed-off-by line based on committer
   identity still passes 1 to make sure it barfs instead of
   adding a bogus s-o-b line.

 - log_ref_write in refs.c, to come up with the name to record
   who initiated the ref update in the reflog, passes -1.  It
   used to barf and die.

The last change means that git-update-ref, git-branch, and
commit walker backends can now be used in a repository with
reflog by somebody who does not have the user identity required
to make a commit.  They all used to barf and die.

I've run tests and all of them seem to pass, and also tried "git
clone" as a user whose GECOS is empty -- git clone works again
now (it was broken when reflog was enabled by default).

But this definitely needs extra sets of eyeballs.

Jeff King 90f70a910a format-patch: fix bug with --stdout in a subdirectory
We set the output directory to the git subdirectory prefix if one has
not already been specified. However, in the case of --stdout, we
explicitly _don't_ want the output directory to be set. The result was
that "git-format-patch --stdout" in a directory besides the project root
produced the "standard output, or directory, which one?" error message.
