The "--show-all" revision option shows UNINTERESTING
commits. Some of these commits may be unparsed when we try
to show them (since we may or may not need to walk their
parents to fulfill the request).
Commit 3131b71301 (Add "--show-all" revision walker flag for
debugging, 2008-02-09) resolved this by just skipping
pretty-printing for commits without their object contents
cached, saying:
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 was the easy fix to avoid the pretty-printer segfaulting,
but:
1. It doesn't work for all formats. E.g., --oneline
prints the oid for each such commit but not a trailing
newline, leading to jumbled output.
2. It only affects some commits, depending on whether we
happened to parse them or not (so if they were at the
tip of an UNINTERESTING starting point, or if we
happened to traverse over them, you'd see more data).
3. It unncessarily ties the decision to show the verbose
header to whether the commit buffer was cached. That
makes it harder to change the logic around caching
(e.g., if we could traverse without actually loading
the full commit objects).
These days it's safe to feed such a commit to the
pretty-print code. Since be5c9fb904 (logmsg_reencode: lazily
load missing commit buffers, 2013-01-26), we'll load it on
demand in such a case. So let's just always show the verbose
headers.
This does change the behavior of plumbing, but:
a. The --show-all option was explicitly introduced as a
debugging aid, and was never documented (and has rarely
even been mentioned on the list by git devs).
b. Avoiding the commits was already not deterministic due
to (2) above. So the caller might have seen full
headers for these commits anyway, and would need to be
prepared for it.

When `log --decorate` is used, git will decorate commits with all
available refs. While in most cases this may give the desired effect,
under some conditions it can lead to excessively verbose output.
Introduce two command line options, `--decorate-refs=<pattern>` and
`--decorate-refs-exclude=<pattern>` to allow the user to select which
refs are used in decoration.
When "--decorate-refs=<pattern>" is given, only the refs that match the
pattern are used in decoration. The refs that match the pattern when
"--decorate-refs-exclude=<pattern>" is given, are never used in
decoration.
These options follow the same convention for mixing negative and
positive patterns across the system, assuming that the inclusive default
is to match all refs available.
(1) if there is no positive pattern given, pretend as if an
inclusive default positive pattern was given;
(2) for each candidate, reject it if it matches no positive
pattern, or if it matches any one of the negative patterns.
The rules for what is considered a match are slightly different from the
rules used elsewhere.
Commands like `log --glob` assume a trailing '/*' when glob chars are
not present in the pattern. This makes it difficult to specify a single
ref. On the other hand, commands like `describe --match --all` allow
specifying exact refs, but do not have the convenience of allowing
"shorthand refs" like 'refs/heads' or 'heads' to refer to
'refs/heads/*'.
The commands introduced in this patch consider a match if:
(a) the pattern contains globs chars,
and regular pattern matching returns a match.
(b) the pattern does not contain glob chars,
and ref '<pattern>' exists, or if ref exists under '<pattern>/'
This allows both behaviours (allowing single refs and shorthand refs)
yet remaining compatible with existent commands.

The resolve_ref_unsafe() function may return NULL even with
a REF_ISSYMREF flag if a symref points to a broken ref. As a
result, it's possible for the decoration code's "is this
branch the current HEAD" check to segfault when it passes
the NULL to starts_with().
This is unlikely in practice, since we can only reach this
code if we already resolved HEAD to a matching sha1 earlier.
But it's possible if HEAD racily becomes broken, or if
there's a transient filesystem error.
We can fix this by returning early in the broken case, since
NULL could not possibly match any of our branch names.

We are about to teach the log-tree machinery to reuse the diffopt.file
field to output to a file stream other than stdout, in line with the
diff machinery already writing to diffopt.file.
However, we might want to write something after the diff in
log_tree_commit() (e.g. with the --show-linear-break option), therefore
we must not let the diff machinery close the file (as per
diffopt.close_file.
This means that log_tree_commit() itself must override the
diffopt.close_file flag and close the file, and if log_tree_commit() is
called in a loop, the caller is responsible to do the same.
Note: format-patch has an `--output-directory` option. Due to the fact
that format-patch's options are parsed first, and that the parse-options
machinery accepts uniquely abbreviated options, the diff options
`--output` (and `-o`) are shadowed. Therefore close_file is not set to 1
so that cmd_format_patch() does *not* need to handle the close_file flag
differently, even if it calls log_tree_commit() in a loop.

This output format prevents format-patch output from breaking
readers if somebody copy+pasted an mbox into a commit message.
Unlike the traditional "mboxo" format, "mboxrd" is designed to
be fully-reversible. "mboxrd" also gracefully degrades to
showing extra ">" in existing "mboxo" readers.
This degradation is preferable to breaking message splitting
completely, a problem I've seen in "mboxcl" due to having
multiple, non-existent, or inaccurate Content-Length headers.
"mboxcl2" is a non-starter since it's inherits the problems
of "mboxcl" while being completely incompatible with existing

In preparation for adding date modes that may carry extra
information beyond the mode itself, this patch converts the
date_mode enum into a struct.
Most of the conversion is fairly straightforward; we pass
the struct as a pointer and dereference the type field where
necessary. Locations that declare a date_mode can use a "{}"
constructor. However, the tricky case is where we use the
enum labels as constants, like:
show_date(t, tz, DATE_NORMAL);
Ideally we could say:
show_date(t, tz, &{ DATE_NORMAL });
but of course C does not allow that. Likewise, we cannot
cast the constant to a struct, because we need to pass an
actual address. Our options are basically:
1. Manually add a "struct date_mode d = { DATE_NORMAL }"
definition to each caller, and pass "&d". This makes
the callers uglier, because they sometimes do not even
have their own scope (e.g., they are inside a switch
statement).
2. Provide a pre-made global "date_normal" struct that can
be passed by address. We'd also need "date_rfc2822",
"date_iso8601", and so forth. But at least the ugliness
is defined in one place.
3. Provide a wrapper that generates the correct struct on
the fly. The big downside is that we end up pointing to
a single global, which makes our wrapper non-reentrant.
But show_date is already not reentrant, so it does not
matter.
This patch implements 3, along with a minor macro to keep
the size of the callers sane.

The previous step to teach "log --decorate" to show "HEAD -> master"
instead of "HEAD, master" when showing the commit at the tip of the
'master' branch, when the 'master' branch is checked out, did not
work for "log --decorate=full".
The commands in the "log" family prepare commit decorations for all
refs upfront, and the actual string used in a decoration depends on
how load_ref_decorations() is called very early in the process. By
default, "git log --decorate" stores names with common prefixes such
as "refs/heads" stripped; "git log --decorate=full" stores the full
refnames.
When the current_pointed_by_HEAD() function has to decide if "HEAD"
points at the branch a decoration describes, however, what was
passed to load_ref_decorations() to decide to strip (or keep) such a
common prefix is long lost. This makes it impossible to reliably
tell if a decoration that stores "refs/heads/master", for example,
is the 'master' branch (under "--decorate" with prefix omitted) or
'refs/heads/master' branch (under "--decorate=full").
Keep what was passed to load_ref_decorations() in a global next to
the global variable name_decoration, and use that to decide how to
match what was read from "HEAD" and what is in a decoration.

In "git log --decorate", you would see the commit header like this:

where "commit ... (" is painted in color.diff.commit, "HEAD" in
color.decorate.head, ", " in color.diff.commit, the branch name in
color.decorate.branch and then closing ")" in color.diff.commit.
If you wanted to paint the HEAD and local branch name in the same
color as the body text (perhaps because cyan and green are too faint
on a black-on-white terminal to be readable), you would not want to
have to say
[color "decorate"]
head = black
branch = black
because that you would not be able to reuse same configuration on a
white-on-black terminal. You would naively expect
[color "decorate"]
head = normal
branch = normal
to work, but unfortunately it does not. It paints the string "HEAD"
and the branch name in the same color as the opening parenthesis or
comma between the decoration elements. This is because the code
forgets to reset the color after printing the "prefix" in its own
color.
It theoretically is possible that some people were expecting and
relying on that the attribute set as the "diff.commit" color, which
is used to draw these opening parenthesis and inter-item comma, is
inherited by the drawing of branch names, but it is not how the
coloring works everywhere else.

Originally the color-parsing function was used only for
config variables. It made sense to pass the variable name so
that the die() message could be something like:
$ git -c color.branch.plain=bogus branch
fatal: bad color value 'bogus' for variable 'color.branch.plain'
These days we call it in other contexts, and the resulting
error messages are a little confusing:
$ git log --pretty='%C(bogus)'
fatal: bad color value 'bogus' for variable '--pretty format'
$ git config --get-color foo.bar bogus
fatal: bad color value 'bogus' for variable 'command line'
This patch teaches color_parse to complain only about the
value, and then return an error code. Config callers can
then propagate that up to the config parser, which mentions
the variable name. Other callers can provide a custom
message. After this patch these three cases now look like:
$ git -c color.branch.plain=bogus branch
error: invalid color value: bogus
fatal: unable to parse 'color.branch.plain' from command-line config
$ git log --pretty='%C(bogus)'
error: invalid color value: bogus

Many config-parsing helpers, like parse_branch_color_slot,
take the name of a config variable and an offset to the
"slot" name (e.g., "color.branch.plain" is passed along with
"13" to effectively pass "plain"). This is leftover from the
time that these functions would die() on error, and would
want the full variable name for error reporting.
These days they do not use the full variable name at all.
Passing a single pointer to the slot name is more natural,
and lets us more easily adjust the callers to use skip_prefix
to avoid manually writing offset numbers.
This is effectively a continuation of 9e1a5eb, which did the

In the previous commit, we made add_name_decoration global
so that adders would not have to access the hash directly.
We now make the hash itself static so that callers _have_ to
add through our function, making sure that all additions go
through a single point. To do this, we have to add one more
accessor function: a way to lookup entries in the hash.
Since the only caller doesn't actually look at the returned
value, but rather only asks whether there is a decoration or
not, we could provide only a boolean "has_name_decoration".
That would allow us to make "struct name_decoration" local
to log-tree, as well.
However, it's unlikely to cause any maintainability harm
making the actual data public, and this interface is more
flexible if we need to look at decorations from other parts

The log-tree code keeps a "struct decoration" hash to show
text decorations for each commit during log traversals. It
makes this available to other files by providing global
access to the hash. This can result in other code adding
entries that do not conform to what log-tree expects.
For example, the bisect code adds its own "dist"
decorations to be shown. Originally the bisect code was
correct, but when the name_decoration code grew a new field
in eb3005e (commit.h: add 'type' to struct name_decoration,
2010-06-19), the bisect code was not updated. As a result,
the log-tree code can access uninitialized memory and even
segfault.
We can fix this by making name_decoration's adding function
public. If all callers use it, then any changes to struct
initialization only need to happen in one place (and because
the members come in as parameters, the compiler can notice a
caller who does not supply enough information).
As a bonus, this also means that the decoration hashes
created by the bisect code will use less memory (previously
we over-allocated space for the distance integer, but now we
format it into a temporary buffer and copy it to the final
flex-array).

If the user provides an empty format with "--format=", we
end up putting in extra whitespace that the user cannot
prevent. This comes from two places:
1. If the format is missing a terminating newline, we add
one automatically. This makes sense for --format=%h, but
not for a truly empty format.
2. We add an extra newline between the pretty-printed
format and a diff or diffstat. If the format is empty,
there's no point in doing so if there's nothing to
separate.
With this patch, one can get a diff with no other cruft out
of "diff-tree --format= $commit".

A wrong '}' made our code record the results of mergetag signature
verification incorrectly.
Fix it.

The git log --graph --show-signature command incorrectly indents the gpg
information about signed commits and merged signed tags. It does not
follow the level of indentation of the current commit.
Example of garbled output:
$ git log --show-signature --graph

In log-tree.c modify show_sig_lines() function to call graph_show_oneline()
after each line of gpg information it has printed in order to preserve
the level of indentation for the next output line.

In the same way as there is for_each_ref() to iterate on refs,
for_each_mergetag() allows the caller to iterate on the mergetags of
a given commit. Use it to rewrite show_mergetag() used in "git log".
