The "git range-diff" command learned "--(left|right)-only" option
to show only one side of the compared range.
* js/range-diff-one-side-only:
range-diff: offer --left-only/--right-only options
range-diff: move the diffopt initialization down one layer
range-diff: combine all options in a single data structure
range-diff: simplify code spawning `git log`
range-diff: libify the read_patches() function again
range-diff: avoid leaking memory in two error code paths
|

In the `SPECIFYING RANGES` section of gitrevisions[7], two ways are
described to specify commit ranges that `range-diff` does not yet
accept: "<commit>^!" and "<commit>^-<n>".
Let's accept them, by parsing them via the revision machinery and
looking for at least one interesting and one uninteresting revision in
the resulting `pending` array.
This also finally lets us reject arguments that _do_ contain `..` but
are not actually ranges, e.g. `HEAD^{/do.. match this}`.

When comparing commit ranges, one is frequently interested only in one
side, such as asking the question "Has this patch that I submitted to
the Git mailing list been applied?": one would only care about the part
of the output that corresponds to the commits in a local branch.
To make that possible, imitate the `git rev-list` options `--left-only`
and `--right-only`.
This addresses https://github.com/gitgitgadget/git/issues/206

It is actually only the `output()` function that uses those diffopts. By
moving the diffopt initialization down into that function, it is
encapsulated better.
Incidentally, it will also make it easier to implement the `--left-only`
and `--right-only` options in `git range-diff` because the `output()`
function is now receiving all range-diff options as a parameter, not
just the diffopts.

Previously, we waited for the child process to be finished in every
failing code path as well as at the end of the function
`show_range_diff()`.
However, we do not need to wait that long. Directly after reading the
output of the child process, we can wrap up the child process.
This also has the advantage that we don't do a bunch of unnecessary work
in case `finish_command()` returns with an error anyway.

In library functions, we do want to avoid the (simple, but rather final)
`die()` calls, instead returning with a value indicating an error.
Let's do exactly that in the code introduced in b66885a30cb8

wants to error out if a diff header could not be parsed.

Currently, when called with exactly two arguments, `git range-diff`
tests for a literal `..` in each of the two. Likewise, the argument
provided via `--range-diff` to `git format-patch` is checked in the same
manner.
However, `<commit>^!` is a perfectly valid commit range, equivalent to
`<commit>^..<commit>` according to the `SPECIFYING RANGES` section of
gitrevisions[7].
In preparation for allowing more sophisticated ways to specify commit
ranges, let's refactor the check into its own function.

hashmap_free(), hashmap_free_entries(), and hashmap_free_() have existed
for a while, but aren't necessarily the clearest names, especially with
hashmap_partial_clear() being added to the mix and lazy-initialization
now being supported. Peff suggested we adopt the following names[1]:
- hashmap_clear() - remove all entries and de-allocate any
hashmap-specific data, but be ready for reuse
- hashmap_clear_and_free() - ditto, but free the entries themselves
- hashmap_partial_clear() - remove all entries but don't deallocate
table
- hashmap_partial_clear_and_free() - ditto, but free the entries
This patch provides the new names and converts all existing callers over
to the new naming scheme.

The "argc" and "argv" names made sense when the struct was argv_array,
but now they're just confusing. Let's rename them to "nr" (which we use
for counts elsewhere) and "v" (which is rather terse, but reads well
when combined with typical variable names like "args.v").
Note that we have to update all of the callers immediately. Playing
tricks with the preprocessor is hard here, because we wouldn't want to
rewrite unrelated tokens.

Code which split an argv_array call across multiple lines, like:
argv_array_pushl(&args, "one argument",
"another argument", "and more",
NULL);
was recently mechanically renamed to use strvec, which results in
mis-matched indentation like:
strvec_pushl(&args, "one argument",
"another argument", "and more",
NULL);
Let's fix these up to align the arguments with the opening paren. I did
this manually by sifting through the results of:
git jump grep 'strvec_.*,$'
and liberally applying my editor's auto-format. Most of the changes are
of the form shown above, though I also normalized a few that had
originally used a single-tab indentation (rather than our usual style of
aligning with the open paren). I also rewrapped a couple of obvious
cases (e.g., where previously too-long lines became short enough to fit
on one), but I wasn't aggressive about it. In cases broken to three or
more lines, the grouping of arguments is sometimes meaningful, and it
wasn't worth my time or reviewer time to ponder each case individually.

We eventually want to drop the argv_array name and just use strvec
consistently. There's no particular reason we have to do it all at once,
or care about interactions between converted and unconverted bits.
Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).
This patch converts all of the remaining files, as the resulting diff is
reasonably sized.
The conversion was done purely mechanically with:
git ls-files '*.c' '*.h' |
xargs perl -i -pe '
s/ARGV_ARRAY/STRVEC/g;
s/argv_array/strvec/g;
'
We'll deal with any indentation/style fallouts separately.

If the supplied integer for "precision" is negative in
`"%.*s", len, line` then it is ignored. So the current code is
equivalent to just `"%s", line` because it is executed only if
`len` is negative.
Fix this by saving the value of `len` before overwriting it with the
return value of `parse_git_diff_header()`.

`git range-diff` calls `git log` internally and tries to parse its
output. But `git log` output can be customized by the user in their
git config and for certain configurations either an error will be
returned by `git range-diff` or it will crash.
To fix this explicitly set the output format of the internally
executed `git log` with `--pretty=medium`. Because that cancels
`--notes`, add explicitly `--notes` at the end.
Also, make sure we never crash in the same way - trying to dereference
`util` which was never created and has remained NULL. It would happen
if the first line of `git log` output does not begin with 'commit '.
Alternative considered but discarded - somehow disable all git configs
and behave as if no config is present in the internally executed
`git log`, but that does not seem to be possible. GIT_CONFIG_NOSYSTEM
is the closest to it, but even with that we would still read
`.git/config`.

When notes were included in the output of range-diff, they were just
mashed together with the rest of the commit message. As a result, users
wouldn't be able to clearly distinguish where the commit message ended
and where the notes started.
Output a `## Notes ##` header when notes are detected so that notes can
be compared more clearly.
Note that we handle case of `Notes (<ref>): -> ## Notes (<ref>) ##` with
this code as well. We can't test this in this patch, however, since
there is currently no way to pass along different notes refs to `git
log`. This will be fixed in a future patch.

we can rely on OFFSETOF_VAR to get the correct offset without

When parsing the diffs, `range-diff` expects to see the prefixes `a/`
and `b/` in the diff headers.
These prefixes can be forced off via the config setting
`diff.noprefix=true`. As `range-diff` is not prepared for that
situation, this will cause a segmentation fault.
Let's avoid that by passing the `--no-prefix` option to the `git log`
process that generates the diffs that `range-diff` wants to parse.
And of course expect the output to have no prefixes, then.

Add the section headers/hunk headers we introduced in the previous
commits to the outer diff's hunk headers. This makes it easier to
understand which change we are actually looking at. For example an
outer hunk header might now look like:
@@ Documentation/config/interactive.txt
while previously it would have only been

which doesn't give a lot of context for the change that follows.

Add the filename to the inner diffs header, so it's always visible to

Currently range-diff keeps the diff header of the inner diff
intact (apart from stripping lines starting with index). This diff
header is somewhat useful, especially when files get different
names in different ranges.
However there is no real need to keep the whole diff header for that.
The main reason we currently do that is probably because it is easy to
do.
Introduce a new range diff hunk header, that's enclosed by "##",
similar to how line numbers in diff hunks are enclosed by "@@", and
give human readable information of what exactly happened to the file,
including the file name.
This improves the readability of the range-diff by giving more concise
information to the users. For example if a file was renamed in one
iteration, but not in another, the diff of the headers would be quite
noisy. However the diff of a single line is concise and should be
easier to understand.
Additionally, this allows us to add these range diff section headers to
the outer diffs hunk headers using a custom userdiff pattern, which
should help making the range-diff more readable.

The line count in the outer diff's hunk headers of a range diff is not
all that interesting. It merely shows how far along the inner diff
are on both sides. That number is of no use for human readers, and
range-diffs are not meant to be machine readable.
In a subsequent commit we're going to add some more contextual
information such as the filename corresponding to the diff to the hunk
headers. Remove the unnecessary information, and just keep the "@@"
to indicate that a new hunk of the outer diff is starting.

When postprocessing the inner diff in range-diff, we currently replace
the whole hunk header line with just "@@". This matches how 'git
tbdiff' used to handle hunk headers as well.
Most likely this is being done because line numbers in the hunk header
are not relevant without other changes. They can for example easily
change if a range is rebased, and lines are added/removed before a
change that we actually care about in our ranges.
However it can still be useful to have the function name that 'git
diff' extracts as additional context for the change.
Note that it is not guaranteed that the hunk header actually shows up
in the range-diff, and this change only aims to improve the case where
a hunk header would already be included in the final output.

Currently range-diff uses the 'strbuf_getline()' function for doing
its line by line processing. In a future patch we want to do parts of
that parsing using the 'parse_git_diff_header()' function. That
function does its own line by line reading of the input, and doesn't
use strbufs. This doesn't match with how we do the line-by-line
processing in range-diff currently.

Stop leaking how the primary output of format-patch is customized to

"reasonable default", in order to correct the breakage introduced by
a5170794 ("Merge branch 'ab/range-diff-no-patch'", 2018-11-18) on
the 'master' front. "git format-patch --range-diff..." without any
weird diff option started to include the "range-diff --stat" output,
which is rather useless right now, that made the whole thing

The "--no-patch" option, which can be used to get a high-level

range-diff: fix regression in passing along diff options

Make the behavior when diff options (e.g. "--stat") are passed
consistent with how "diff" behaves.
Before 73a834e9e2 ("range-diff: relieve callers of low-level
configuration burden", 2018-07-22) running range-diff with "--stat"
would produce stat output and the diff output, as opposed to how
"diff" behaves where once "--stat" is specified "--patch" also needs
to be provided to emit the patch output.
As noted in a previous change ("range-diff doc: add a section about
output stability", 2018-11-07) the "--stat" output with "range-diff"
is useless at the moment.
But we should behave consistently with "diff" in anticipation of such
output being useful in the future, because it would make for confusing
UI if "diff" and "range-diff" behaved differently when it came to how
they interpret diff options.
The new behavior is also consistent with the existing documentation
added in ba931edd28 ("range-diff: populate the man page",
2018-08-13). See "[...]also accepts the regular diff options[...]" in

As noted in a change leading up to this ("range-diff doc: add a

does not need to even bother generating a hunk header line, saving a

The previous commit taught xdiff to optionally provide the hunk header
data to a specialized callback. But most users of xdiff actually use our
more convenient xdi_diff_outf() helper, which ensures that our callbacks
are always fed whole lines.
Let's plumb the special hunk-callback through this interface, too. It
will follow the same rule as xdiff when the hunk callback is NULL (i.e.,
continue to pass a stringified hunk header to the line callback). Since
we add NULL to each caller, there should be no behavior change yet.

If we have `submodule.diff = log' in the configuration file
or `--submodule=log' is given as argument, range-diff fails
to compare both diffs and we only get the following output:
Submodule a 0000000...0000000 (new submodule)
Even if the repository doesn't have any submodule.
That's because the mode in diff_filespec is not correct and when
flushing the diff, down in builtin_diff() we will enter the condition:
if (o->submodule_format == DIFF_SUBMODULE_LOG &&
(!one->mode || S_ISGITLINK(one->mode)) &&
(!two->mode || S_ISGITLINK(two->mode))) {
show_submodule_summary(o, one->path ? one->path : two->path,
&one->oid, &two->oid,
two->dirty_submodule);
return;
It turns out that S_ISGITLINK will return true (mode == 0160000 here).
Similar thing happens if submodule.diff is "diff".
Do like it's done in grep.c when calling fill_filespec() and force it to
be recognized as a file by adding S_IFREG to the mode.

The range-diff coloring is a bit fuzzy when it comes to special lines of
a diff, such as indicating new and old files with +++ and ---, as it
would pickup the first character and interpret it for its coloring, which
seems annoying as in regular diffs, these lines are colored bold via
DIFF_METAINFO.
By indenting these lines by a white space, they will be treated as context
which is much more useful, an example [1] on the range diff series itself:
[...]
+ diff --git a/Documentation/git-range-diff.txt b/Documentation/git-range-diff.txt
+ new file mode 100644
+ --- /dev/null
+ +++ b/Documentation/git-range-diff.txt
+@@
++git-range-diff(1)
[...]
+
diff --git a/Makefile b/Makefile
--- a/Makefile
+++ b/Makefile
[...]
The first lines that introduce the new file for the man page will have the
'+' sign colored and the rest of the line will be bold.
The later lines that indicate a change to the Makefile will be treated as
context both in the outer and inner diff, such that those lines stay
regular color.

This change itself only changes the internal communication and should
have no visible effect to the user. We instruct the diff code that
produces the inner diffs to use other markers instead of the
usual markers for new, old and context lines.

There are a number of very low-level configuration details which need to
be managed precisely to generate a proper range-diff. In particular,
'diff_options' output format, header suppression, indentation, and
dual-color mode must all be set appropriately to ensure proper behavior.
Handle these details locally in the libified range-diff back-end rather
than forcing each caller to have specialized knowledge of these
implementation details, and to avoid duplication as new callers are
added.
While at it, localize these tweaks to be active only while generating
the range-diff, so they don't clobber the caller-provided
'diff_options', which might be used beyond range-diff generation.

The actual diffs output by range-diff respect diff_option.file, which
range-diff passes down the call-chain, thus are destination-agnostic.
However, output_pair_header() is hard-coded to emit to 'stdout'. Fix
this by making output_pair_header() respect diff_option.file, as well.

As pointed out by Elijah Newren, tbdiff has this neat little alignment
trick where it outputs the commit pairs with patch numbers that are
padded to the maximal patch number's width:
1: cafedead = 1: acefade first patch
[...]
314: beefeada < 314: facecab up to PI!
Let's do the same in range-diff, too.

Arguably the most important part of `git range-diff`'s output is the
list of commits in the two branches, together with their relationships.
For that reason, tbdiff introduced color-coding that is pretty
intuitive, especially for unchanged patches (all dim yellow, like the
first line in `git show`'s output) vs modified patches (old commit is
red, new commit is green). Let's imitate that color scheme.
