Maybe something like this:

Here's what that generates on my machine, with annotations:
[builtin/am.c:766]: (error) Resource leak: in
Correct.
[builtin/notes.c:260]: (error) Memory pointed to by 'buf' is freed twice.
[builtin/notes.c:264]: (error) Memory pointed to by 'buf' is freed twice.
Nope. It appears not to understand that die() does not return.
[builtin/rev-list.c:391]: (error) Uninitialized variable: reaches
[builtin/rev-list.c:391]: (error) Uninitialized variable: all
These are "int foo = foo" (which is ugly, and maybe we can get rid of
if compilers have gotten smart enough to figure it out).
[compat/nedmalloc/malloc.c.h:4646]: (error) Memory leak: mem
Hard to tell, but I think this is wrong and is confused by pointer
arithmetic on the malloc chunks.
[compat/regex/regcomp.c:3086]: (error) Memory leak: sbcset
Nope, this return is hit only when sbcset is NULL. The tool is
presumably confused by a conditional hidden inside a macro.
[compat/regex/regcomp.c:3634]: (error) Memory leak: sbcset
[compat/regex/regcomp.c:3086]: (error) Memory leak: mbcset
[compat/regex/regcomp.c:3634]: (error) Memory leak: mbcset
I didn't look at these, but presumably similar.
[compat/regex/regcomp.c:2802]: (error) Uninitialized variable: table_size
[compat/regex/regcomp.c:2805]: (error) Uninitialized variable: table_size
Not sure, but it looks like this function declares another inline
function inside its scope, and that confuses the tool.
[compat/regex/regcomp.c:532]: (error) Memory leak: fastmap
Nope. Tool seems confused by hiding free() in a macro.
[contrib/examples/builtin-fetch--tool.c:420]: (error) Uninitialized variable: lrr_count
[contrib/examples/builtin-fetch--tool.c:427]: (error) Uninitialized variable: lrr_list
More "int foo = foo". Might be worth omitting contrib/examples (or
possibly contrib/ entirely) from the check.
[t/helper/test-hashmap.c:125]: (error) Memory leak: entries
[t/helper/test-hashmap.c:125]: (error) Memory leak: hashes
Correct (but unimportant).
So I think it is capable of finding real problems, but I think we'd need
some way of squelching false positives, preferably in a way that carries
forward as the code changes (so not just saying "foo.c:1234 is a false
positive", which will break when it becomes "foo.c:1235").

* [PATCH] builtin/commit.c: convert trivial snprintf calls to xsnprintf
From: Elia Pinto @ 2016-12-13 13:27 UTC (permalink / raw)
To: git; +Cc: Elia Pinto
With the commits f2f02675 and 5096d490 we have been converted in some files the call from snprintf/sprintf/strcpy to xsnprintf. This patch supersedes the
snprintf with several calls that make use of the heap rather than fixed
length buffers (eg. PATH_MAX) that may be incorrect on some systems.

I had trouble parsing this, because it leads with mention of commits
that _aren't_ doing the same thing we are doing here. I think the
argument you want to make is basically:
1. snprintf is bad because it may silently truncate results if we're
wrong.
2. In cases where we use PATH_MAX, we'd want to handle larger paths
anyway, so we should switch to dynamic allocation.
3. In other cases where we know the input is bounded to a certain
length we could use xsnprintf(), which asserts that we don't
truncate. But by switching to dynamic allocation, we can avoid
dealing with magic numbers in the code.
I'd actually consider splitting cases (2) and (3) into separate patches.
Even though the end result is the same, the reasoning is quite
different.
As far as the patch itself goes, they all look like improvements to me.
The extra allocations shouldn't matter because these are all heavy
operations already.

I'd generally skip the clear() right before exiting, though I saw
somebody disagree with me recently on that. I wonder if we should
decide as a project on whether it is worth doing or not.

Any time you care about the length of the result, I'd generally use an
actual strbuf instead of xstrfmt. The extra strlen isn't a big deal
here, but it somehow seems simpler to me. It probably doesn't matter
much either way, though.

Missing whitespace between arguments in the run_hook_ve() call.

* [PATCH v2 04/34] sequencer (rebase -i): implement the 'exec' command
From: Johannes Schindelin @ 2016-12-13 15:29 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
The 'exec' command is a little special among rebase -i's commands, as it
does *not* have a SHA-1 as first parameter. Instead, everything after the
`exec` command is treated as command-line to execute.
Let's reuse the arg/arg_len fields of the todo_item structure (which hold
the oneline for pick/edit commands) to point to the command-line.

* [PATCH v2 03/34] sequencer (rebase -i): implement the 'edit' command
From: Johannes Schindelin @ 2016-12-13 15:29 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
This patch is a straight-forward reimplementation of the `edit`
operation of the interactive rebase command.
Well, not *quite* straight-forward: when stopping, the `edit`
command wants to write the `patch` file (which is not only the
patch, but includes the commit message and author information). To
that end, this patch requires the earlier work that taught the
log-tree machinery to respect the `file` setting of
rev_info->diffopt to write to a file stream different than stdout.

* [PATCH v2 12/34] sequencer (rebase -i): skip some revert/cherry-pick specific code path
From: Johannes Schindelin @ 2016-12-13 15:30 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
When a cherry-pick continues without a "todo script", the intention is
simply to pick a single commit.
However, when an interactive rebase is continued without a "todo
script", it means that the last command has been completed and that we
now need to clean up.
This commit guards the revert/cherry-pick specific steps so that they
are not executed in rebase -i mode.

* [PATCH v2 14/34] sequencer (rebase -i): update refs after a successful rebase
From: Johannes Schindelin @ 2016-12-13 15:30 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
An interactive rebase operates on a detached HEAD (to keep the reflog
of the original branch relatively clean), and updates the branch only
at the end.
Now that the sequencer learns to perform interactive rebases, it also
needs to learn the trick to update the branch before removing the
directory containing the state of the interactive rebase.
We introduce a new head_ref variable in a wider scope than necessary at
the moment, to allow for a later patch that prints out "Successfully
rebased and updated <ref>".

In the interactive rebase, commands that were successfully processed are
not simply discarded, but appended to the 'done' file instead. This is
used e.g. to display the current state to the user in the output of
`git status` or the progress.

When calling `git rebase -i -v`, the user wants to see some statistics
after the commits were rebased. Let's show some.
The strbuf we use to perform that task will be used for other things
in subsequent commits, hence it is declared and initialized in a wider
scope than strictly needed here.

* [PATCH v2 07/34] sequencer (rebase -i): add support for the 'fixup' and 'squash' commands
From: Johannes Schindelin @ 2016-12-13 15:30 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
This is a huge patch, and at the same time a huge step forward to
execute the performance-critical parts of the interactive rebase in a
builtin command.
Since 'fixup' and 'squash' are not only similar, but also need to know
about each other (we want to reduce a series of fixups/squashes into a
single, final commit message edit, from the user's point of view), we
really have to implement them both at the same time.
Most of the actual work is done by the existing code path that already
handles the "pick" and the "edit" commands; We added support for other
features (e.g. to amend the commit message) in the patches leading up to
this one, yet there are still quite a few bits in this patch that simply
would not make sense as individual patches (such as: determining whether
there was anything to "fix up" in the "todo" script, etc).
In theory, it would be possible to reuse the fast-forward code path also
for the fixup and the squash code paths, but in practice this would make
the code less readable. The end result cannot be fast-forwarded anyway,
therefore let's just extend the cherry-picking code path for now.
Since the sequencer parses the entire `git-rebase-todo` script in one go,
fixup or squash commands without a preceding pick can be reported early
(in git-rebase--interactive, we could only report such errors just before
executing the fixup/squash).

* [PATCH v2 13/34] sequencer (rebase -i): the todo can be empty when continuing
From: Johannes Schindelin @ 2016-12-13 15:30 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
When the last command of an interactive rebase fails, the user needs to
resolve the problem and then continue the interactive rebase. Naturally,
the todo script is empty by then. So let's not complain about that!
To that end, let's move that test out of the function that parses the
todo script, and into the more high-level function read_populate_todo().
This is also necessary by now because the lower-level parse_insn_buffer()
has no idea whether we are performing an interactive rebase or not.

* [PATCH v2 25/34] sequencer (rebase -i): allow rescheduling commands
From: Johannes Schindelin @ 2016-12-13 15:31 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
The interactive rebase has the very special magic that a cherry-pick
that exits with a status different from 0 and 1 signifies a failure to
even record that a cherry-pick was started.
This can happen e.g. when a fast-forward fails because it would
overwrite untracked files.
In that case, we must reschedule the command that we thought we already
had at least started successfully.

To: git; +Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
Git's `rebase` command inspects the `rebase.autostash` config setting
to determine whether it should stash any uncommitted changes before
rebasing and re-apply them afterwards.
As we introduce more bits and pieces to let the sequencer act as
interactive rebase's backend, here is the part that adds support for
the autostash feature.

* [PATCH v2 21/34] sequencer (rebase -i): record interrupted commits in rewritten, too
From: Johannes Schindelin @ 2016-12-13 15:31 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
When continuing after a `pick` command failed, we want that commit
to show up in the rewritten-list (and its notes to be rewritten), too.

* [PATCH v2 18/34] sequencer (rebase -i): refactor setting the reflog message
From: Johannes Schindelin @ 2016-12-13 15:31 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
This makes the code DRYer, with the obvious benefit that we can enhance
the code further in a single place.
We can also reuse the functionality elsewhere by calling this new
function.

To: git; +Cc: Junio C Hamano, Kevin Daudt, Dennis Kaarsemaker
In-Reply-To: <cover.1481642927.git.johannes.schindelin@gmx.de>
We already used the same reflog message as the scripted version of rebase
-i when finishing. With this commit, we do that also for all the commands
before that.
