Junio C Hamano d041ffa55a log --show-signature: reword the common two-head merge case
While identifying the commit merged to our history as "parent #2" is
technically correct, we will never say "parent #1" (as that is the tip of
our history before the merge is made), and we rarely would say "parent #3"
(which would mean the merge is an octopus), especially when responding to
a request to pull a signed tag.

Treat the most common case to merge a single commit specially, and just
say "merged tag '<tagname>'" instead.

The next patch needs to show the result of signature verification on a

This teaches the "log" family of commands to pass the GPG signature in the
commit objects to "gpg --verify" via the verify_signed_buffer() interface

Jeff King daa0c3d971 color: delay auto-color decision until point of use
When we read a color value either from a config file or from
the command line, we use git_config_colorbool to convert it
from the tristate always/never/auto into a single yes/no
boolean value.

This has some timing implications with respect to starting
a pager.

If we start (or decide not to start) the pager before
checking the colorbool, everything is fine. Either isatty(1)
will give us the right information, or we will properly
check for pager_in_use().

However, if we decide to start a pager after we have checked
the colorbool, things are not so simple. If stdout is a tty,
then we will have already decided to use color. However, the
user may also have configured color.pager not to use color
with the pager. In this case, we need to actually turn off
color. Unfortunately, the pager code has no idea which color
variables were turned on (and there are many of them
throughout the code, and they may even have been manipulated
after the colorbool selection by something like "--color" on
the command line).

This bug can be seen any time a pager is started after
config and command line options are checked. This has
affected "git diff" since 89d07f7 (diff: don't run pager if
user asked for a diff style exit code, 2007-08-12). It has
also affect the log family since 1fda91b (Fix 'git log'
early pager startup error case, 2010-08-24).

This patch splits the notion of parsing a colorbool and
actually checking the configuration. The "use_color"
variables now have an additional possible value,
GIT_COLOR_AUTO. Users of the variable should use the new
"want_color()" wrapper, which will lazily determine and
cache the auto-color decision.

Jeff King f1c9626105 diff: refactor COLOR_DIFF from a flag into an int
This lets us store more than just a bit flag for whether we
want color; we can also store whether we want automatic
colors. This can be useful for making the automatic-color
decision closer to the point of use.

This mostly just involves replacing DIFF_OPT_* calls with
manipulations of the flag. The biggest exception is that
calls to DIFF_OPT_TST must check for "o->use_color > 0",
which lets an "unknown" value (i.e., the default) stay at
"no color". In the previous code, a value of "-1" was not
propagated at all.

Jeff King e7af8e49cd format-patch: make zero-length subject prefixes prettier
If you give a zero-length subject prefix to format-patch
(e.g., "format-patch --subject-prefix="), we will print the
ugly:

  Subject: [ 1/2] your subject here

because we always insert a space between the prefix and
numbering. Requiring the user to provide the space in their
prefix would be more flexible, but would break existing
usage. This patch provides a DWIM and suppresses the space
for zero-length prefixes, under the assumption that nobody
actually wants "[ 1/2]".

Jeff King 9553d2b263 format-patch: preserve subject newlines with -k
In older versions of git, we used rfc822 header folding to
indicate that the original subject line had multiple lines
in it.  But since a1f6baa (format-patch: wrap long header
lines, 2011-02-23), we now use header folding whenever there
is a long line.

This means that "git am" cannot trust header folding as a
sign from format-patch that newlines should be preserved.
Instead, format-patch needs to signal more explicitly that
the newlines are significant.  This patch does so by
rfc2047-encoding the newlines in the subject line. No
changes are needed on the "git am" end; it already decodes
the newlines properly.

Jeff King 6bf139440c clean up calling conventions for pretty.c functions
We have a pretty_print_context representing the parameters
for a pretty-print session, but we did not use it uniformly.
As a result, functions kept growing more and more arguments.

Let's clean this up in a few ways:

  1. All pretty-print pp_* functions now take a context.
     This lets us reduce the number of arguments to these
     functions, since we were just passing around the
     context values separately.

  2. The context argument now has a cmit_fmt field, which
     was passed around separately. That's one less argument
     per function.

  3. The context argument always comes first, which makes
     calling a little more uniform.

This drops lines from some callers, and adds lines in a few
places (because we need an extra line to set the context's
fmt field). Overall, we don't save many lines, but the lines
that are there are a lot simpler and more readable.

Petr Baudis 88d9d45d07 git log -p -m: document -m and honor --first-parent
git log -p -m is used to show one merge entry per parent, with an
appropriate diff; this can be useful when examining histories where
full set of changes introduced by a merged branch is interesting, not
only the conflicts.

This patch properly documents the -m switch, which has so far been
mentioned only as a fairly special diff-tree flag.

It also makes the code show full patch entry only for the first parent
when --first-parent is used. Thus:

	git log -p -m --first-parent

will show the history from the "main branch perspective", while also
including full diff of changes introduced by other merged in branches.

Junio C Hamano 66b2ed09c2 Fix "log" family not to be too agressive about showing notes
Giving "Notes" information in the default output format of "log" and
"show" is a sensible progress (the user has asked for it by having the
notes), but for some commands (e.g. "format-patch") spewing notes into the
formatted commit log message without being asked is too aggressive.

Enable notes output only for "log", "show", "whatchanged" by default and
only when the user didn't ask any specific --pretty/--format from the
command line; users can explicitly override this default with --show-notes
and --no-notes option.

Thomas Rast 8f8f5476cd Introduce new pretty formats %g[sdD] for reflog information
Add three new --pretty=format escapes:

  %gD  long  reflog descriptor (e.g. refs/stash@{0})
  %gd  short reflog descriptor (e.g. stash@{0})
  %gs  reflog message

This is achieved by passing down the reflog info, if any, inside the
pretty_print_context struct.

We use the newly refactored get_reflog_selector(), and give it some
extra functionality to extract a shortened ref.  The shortening is
cached inside the commit_reflogs struct; the only allocation of it
happens in read_complete_reflog(), where it is initialised to 0.  Also
add another helper get_reflog_message() for the message extraction.

Note that the --format="%h %gD: %gs" tests may not work in real
repositories, as the --pretty formatter doesn't know to leave away the
": " on the last commit in an incomplete (because git-gc removed the
old part) reflog.  This equivalence is nevertheless the main goal of
this patch.

Thanks to Jeff King for reviews, the %gd testcase and documentation.

Thomas Rast dd2e794a21 Refactor pretty_print_commit arguments into a struct
pretty_print_commit() has a bunch of rarely-used arguments, and
introducing more of them requires yet another update of all the call
sites.  Refactor most of them into a struct to make future extensions
easier.

The ones that stay "plain" arguments were chosen on the grounds that
all callers put real arguments there, whereas some callers have 0/NULL
for all arguments that were factored into the struct.

We declare the struct 'const' to ensure none of the callers are bitten
by the changed (no longer call-by-value) semantics.

Jeff King f4ea32f0b4 improve reflog date/number heuristic
When we show a reflog, we have two ways of naming the entry:
by sequence number (e.g., HEAD@{0}) or by date (e.g.,
HEAD@{10 minutes ago}). There is no explicit option to set
one or the other, but we guess based on whether or not the
user has provided us with a date format, showing them the
date version if they have done so, and the sequence number
otherwise.

This usually made sense if the use did something like "git
log -g --date=relative". However, it didn't make much sense
if the user set the date format using the log.date config
variable; in that case, all of their reflogs would end up as
dates.

This patch records the source of the date format and only
triggers the date-based view if --date= was given on the
command line.

Thomas Rast b079c50e03 format-patch: track several references
Currently, format-patch can only track a single reference (the
In-Reply-To:) for each mail.  To ensure proper threading, we should
list all known references for every mail.

Change the rev_info.ref_message_id field to a string_list, so that we
can append references at will, and change the output formatting
routines to print all of them in the References: header.  The last
entry in the list is implicitly assumed to be the In-Reply-To:, which
gives output consistent with RFC 2822:

   The "References:" field will contain the contents of the parent's
   "References:" field (if any) followed by the contents of the
   parent's "Message-ID:" field (if any).

Note that this is just preparatory work; nothing uses it yet, so all
"References:" fields in the output are still only one deep.

	git show --parents --source $(git rev-list HEAD)

which is admittedly contrived, but can easily happen in scripting.

So use a <tab> instead of a space as the source separator.

The other decorations didn't have this issue, because they were surrounded
by parenthesis, so it's obvious that they aren't parent SHA1's.

It so happens that _visually_ this makes no difference for "git log
--source", since "commit <40-char SHA1>" is 47 characters, so both a space
and a <tab> will end up showing as a single commit. Of course, with
'--pretty=oneline' or '--parents' or '--abbrev-commit' you'll see the
difference.

Linus Torvalds 0f3a290b89 Add a 'source' decorator for commits
We already support decorating commits by tags or branches that point to
them, but especially when we are looking at multiple branches together,
we sometimes want to see _how_ we reached a particular commit.

We can abuse the '->util' field in the commit to keep track of that as
we walk the commit lists, and get a reasonably useful view into which
branch or tag first reaches that commit.

Of course, if the commit is reachable through multiple sources (which is
common), our particular choice of "first" reachable is entirely random
and depends on the particular path we happened to follow.

Kevin Ballard 6b2fbaaffc format-patch: Produce better output with --inline or --attach
This patch makes two small changes to improve the output of --inline
and --attach.

The first is to write a newline preceding the boundary. This is needed because
MIME defines the encapsulation boundary as including the preceding CRLF (or in
this case, just LF), so we should be writing one. Without this, the last
newline in the pre-diff content is consumed instead.

The second change is to always write the line termination character
(default: newline) even when using --inline or --attach. This is simply to
improve the aesthetics of the resulting message. When using --inline an email
client should render the resulting message identically to the non-inline
version. And when using --attach this adds a blank line preceding the
attachment in the email, which is visually attractive.

Junio C Hamano 4da45bef56 log: teach "terminator" vs "separator" mode to "--pretty=format"
This attached patch introduces a single bit "use_terminator" in "struct
rev_info", which is normally false (i.e. most formats use separator
semantics) but by flipping it to true, you can ask for terminator
semantics just like oneline format does.

The function get_commit_format(), which is what parses "--pretty=" option,
now takes a pointer to "struct rev_info" and updates its commit_format and
use_terminator fields.  It used to return the value of type "enum
cmit_fmt", but all the callers assigned it to rev->commit_format.

There are only two cases the code turns use_terminator on.  Obviously, the
traditional oneline format (--pretty=oneline) is one of them, and the new
case is --pretty=tformat:... that acts like --pretty=format:... but flips
the bit on.

With this, "--pretty=tformat:%H %s" acts like --pretty=oneline.

2008-03-15 00:09:33 -07:00
Junio C Hamano 6bf4f1b4c9 format-patch: generate MIME header as needed even when there is format.header
Earlier, the callchain from pretty_print_commit() down to pp_title_line()
had an unwarranted assumption that the presense of "after_subject"
parameter, means the caller has already output MIME headers for
attachments.  The parameter's primary purpose is to give extra header
lines the caller wants to place after pp_title_line() generates the
"Subject: " line.

This assumption does not hold when the user used the format.header
configuration variable to pass extra headers, and caused a message with
non-ASCII character to lack proper MIME headers (e.g.  8-bit CTE header).
The earlier logic also failed to suppress duplicated MIME headers when
"format-patch -s --attach" is asked for and the signer's name demanded
8-bit clean transport.

This patch fixes the logic by introducing a separate need_8bit_cte
parameter passed down the callchain.  This can have one of these values:

 -1 : we've already done MIME crap and we do not want to add extra header
      to say this is 8bit in pp_title_line();

  0 : we haven't done MIME and we have not seen anything that is 8bit yet;

  1 : we haven't done MIME and we have seen something that is 8bit;
      pp_title_line() must add MIME header.

It adds two tests by Jeff King who independently diagnosed this issue.

Linus Torvalds 3131b71301 Add "--show-all" revision walker flag for debugging
It's really not very easy to visualize the commit walker, because - on
purpose - it obvously doesn't show the uninteresting commits!

This adds a "--show-all" flag to the revision walker, which will make
it show uninteresting commits too, and they'll have a '^' in front of
them (it also fixes a logic error for !verbose_header for boundary
commits - we should show the '-' even if left_right isn't shown).

A separate patch to gitk to teach it the new '^' was sent
to paulus.  With the change in place, it actually is interesting
even for the cases that git doesn't have any problems with, ie
for the kernel you can do:

	gitk -d --show-all v2.6.24..

and you see just how far down it has to parse things to see it all. The
use of "-d" is a good idea, since the date-ordered toposort is much better
at showing why it goes deep down (ie the date of some of those commits
after 2.6.24 is much older, because they were merged from trees that
weren't rebased).

So I think this is a useful feature even for non-debugging - just to
visualize what git does internally more.

When it actually breaks out due to the "everybody_uninteresting()"
case, it adds the uninteresting commits (both the one it's looking at
now, and the list of pending ones) to the list

This way, we really list *all* the commits we've looked at.

Because we now end up listing commits we may not even have been parsed
at all "show_log" and "show_commit" need to protect against commits
that don't have a commit buffer entry.

That second part is debatable just how it should work. Maybe we shouldn't
show such entries at all (with this patch those entries do get shown, they
just don't get any message shown with them). But I think this is a useful
case.

the diff.

Theodore Ts'o 06f59e9f5d Don't fflush(stdout) when it's not helpful
This patch arose from a discussion started by Jim Meyering's patch
whose intention was to provide better diagnostics for failed writes.
Linus proposed a better way to do things, which also had the added
benefit that adding a fflush() to git-log-* operations and incremental
git-blame operations could improve interactive respose time feel, at
the cost of making things a bit slower when we aren't piping the
output to a downstream program.

This patch skips the fflush() calls when stdout is a regular file, or
if the environment variable GIT_FLUSH is set to "0".  This latter can
speed up a command such as:

GIT_FLUSH=0 strace -c -f -e write time git-rev-list HEAD | wc -l

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.

commit and the diff. The diff goes hand-in-hand with the commit, it
shouldn't be separated from it with the termination character.

So this:
 - uses the termination character for true inter-commit spacing
 - uses a regular newline between the commit log and the diff

We had it the other way around.

For the normal case where the termination character is '\n', this
obviously doesn't change anything at all, since we just switched two
identical characters around. So it's very safe - it doesn't change any
normal usage, but it definitely fixes "git log -z".

By fixing "git log -z", you can now also do insane things like

	git log -p -z |
		grep -z "some patch expression" |
		tr '\0' '\n' |
		less -S

and you will see only those commits that have the "some patch expression"
in their commit message _or_ their patches.

(This is slightly different from 'git log -S"some patch expression"',
since the latter requires the expression to literally *change* in the
patch, while the "git log -p -z | grep .." approach will see it if it's
just an unchanged _part_ of the patch context)

Of course, if you actually do something like the above, you're probably
insane, but hey, it works!

Try the above command line for a demonstration (of course, you need to
change the "some patch expression" to be something relevant). The old
behaviour of "git log -p -z" was useless (and got things completely wrong
for log entries without patches).

Rene Scharfe 2b60356da5 Make git-cherry handle root trees
This patch on top of 'next' makes built-in git-cherry handle root
commits.

It moves the static function log-tree.c::diff_root_tree() to
tree-diff.c and makes it more similar to diff_tree_sha1() by
shuffling around arguments and factoring out the call to
log_tree_diff_flush().  Consequently the name is changed to
diff_root_tree_sha1().  It is a version of diff_tree_sha1() that
compares the empty tree (= root tree) against a single 'real' tree.

This function is then used in get_patch_id() to compute patch IDs
for initial commits instead of SEGFAULTing, as the current code
does if confronted with parentless commits.

Linus Torvalds a4d34e2db5 Log message printout cleanups (#3): fix --pretty=oneline
This option is very special, since pretty_print_commit() will _remove_
the newline at the end of it, so we want to have an extra separator
between the things.

I added a honking big comment this time, so that (a) I don't forget this
_again_ (I broke "oneline" several times during this printout cleanup),
and so that people can understand _why_ the code does what it does.

Now, arguably the alternate fix is to always have the '\n' at the end in
pretty-print-commit, but git-rev-list depends on the current behaviour
(but we could have git-rev-list remove it, whatever).

With the big comment, the code hopefully doesn't get broken again. And now
things like

	git log --pretty=oneline --cc --patch-with-stat

works (even if that is admittedly a totally insane combination: if you
want the patch, having the "oneline" log format is just crazy, but hey,
it _works_. Even insane people are people).

Linus Torvalds eab144ac49 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.

Linus Torvalds cd2bdc5309 Common option parsing for "git log --diff" and friends
This basically does a few things that are sadly somewhat interdependent,
and nontrivial to split out

 - get rid of "struct log_tree_opt"

   The fields in "log_tree_opt" are moved into "struct rev_info", and all
   users of log_tree_opt are changed to use the rev_info struct instead.

 - add the parsing for the log_tree_opt arguments to "setup_revision()"

 - make setup_revision set a flag (revs->diff) if the diff-related
   arguments were used. This allows "git log" to decide whether it wants
   to show diffs or not.

 - make setup_revision() also initialize the diffopt part of rev_info
   (which we had from before, but we just didn't initialize it)

 - make setup_revision() do all the "finishing touches" on it all (it will
   do the proper flag combination logic, and call "diff_setup_done()")

Now, that was the easy and straightforward part.

The slightly more involved part is that some of the programs that want to
use the new-and-improved rev_info parsing don't actually want _commits_,
they may want tree'ish arguments instead. That meant that I had to change
setup_revision() to parse the arguments not into the "revs->commits" list,
but into the "revs->pending_objects" list.

Then, when we do "prepare_revision_walk()", we walk that list, and create
the sorted commit list from there.

This actually cleaned some stuff up, but it's the less obvious part of the
patch, and re-organized the "revision.c" logic somewhat. It actually paves
the way for splitting argument parsing _entirely_ out of "revision.c",
since now the argument parsing really is totally independent of the commit
walking: that didn't use to be true, since there was lots of overlap with
get_commit_reference() handling etc, now the _only_ overlap is the shared
(and trivial) "add_pending_object()" thing.

However, I didn't do that file split, just because I wanted the diff
itself to be smaller, and show the actual changes more clearly. If this
gets accepted, I'll do further cleanups then - that includes the file
split, but also using the new infrastructure to do a nicer "git diff" etc.

Even in this form, it actually ends up removing more lines than it adds.

It's nice to note how simple and straightforward this makes the built-in
"git log" command, even though it continues to support all the diff flags
too. It doesn't get much simpler that this.

I think this is worth merging soonish, because it does allow for future
cleanup and even more sharing of code. However, it obviously touches
"revision.c", which is subtle. I've tested that it passes all the tests we
have, and it passes my "looks sane" detector, but somebody else should
also give it a good look-over.
