This is the flip side of the previous two patches: checking
for a non-zero oidcmp() can be more strictly expressed as
inequality. Like those patches, we write "!= 0" in the
coccinelle transformation, which covers by isomorphism the
more common:
if (oidcmp(E1, E2))
As with the previous two patches, this patch can be achieved
almost entirely by running "make coccicheck"; the only
differences are manual line-wrap fixes to match the original
code.
There is one thing to note for anybody replicating this,
though: coccinelle 1.0.4 seems to miss the case in
builtin/tag.c, even though it's basically the same as all
the others. Running with 1.0.7 does catch this, so
presumably it's just a coccinelle bug that was fixed in the
interim.

Using the more restrictive oideq() should, in the long run,
give the compiler more opportunities to optimize these
callsites. For now, this conversion should be a complete
noop with respect to the generated code.
The result is also perhaps a little more readable, as it
avoids the "zero is equal" idiom. Since it's so prevalent in
C, I think seasoned programmers tend not to even notice it
anymore, but it can sometimes make for awkward double
negations (e.g., we can drop a few !!oidcmp() instances
here).
This patch was generated almost entirely by the included
coccinelle patch. This mechanical conversion should be
completely safe, because we check explicitly for cases where
oidcmp() is compared to 0, which is what oideq() is doing
under the hood. Note that we don't have to catch "!oidcmp()"
separately; coccinelle's standard isomorphisms make sure the
two are treated equivalently.
I say "almost" because I did hand-edit the coccinelle output
to fix up a few style violations (it mostly keeps the
original formatting, but sometimes unwraps long lines).

Sometimes we want to suppress a coccinelle transformation
inside a particular function. For example, in finding
conversions of hashcmp() to oidcmp(), we should not convert
the call in oidcmp() itself, since that would cause infinite
recursion. We write that like this:
@@
identifier f != oidcmp;
expression E1, E2;
@@
f(...) {...
- hashcmp(E1->hash, E2->hash)
+ oidcmp(E1, E2)
...}
to match the interior of any function _except_ oidcmp().
Unfortunately, this doesn't catch all cases (e.g., the one
in sequencer.c that this patch fixes). The problem, as
explained by one of the Coccinelle developers in [1], is:
For transformation, A ... B requires that B occur on every
execution path starting with A, unless that execution path
ends up in error handling code. (eg, if (...) { ...
return; }). Here your A is the start of the function. So
you need a call to hashcmp on every path through the
function, which fails when you add ifs.
[...]
Another issue with A ... B is that by default A and B
should not appear in the matched region. So your original
rule matches only the case where every execution path
contains exactly one call to hashcmp, not more than one.
One way to solve this is to put the pattern inside an
angle-bracket pattern like "<... P ...>", which allows zero
or more matches of P. That works (and is what this patch
does), but it has one drawback: it matches more than we care
about, and Coccinelle uses extra CPU. Here are timings for
"make coccicheck" before and after this patch:
[before]
real 1m27.122s
user 7m34.451s
sys 0m37.330s
[after]
real 2m18.040s
user 10m58.310s
sys 0m41.549s
That's not ideal, but it's more important for this to be
correct than to be fast. And coccicheck is already fairly
slow (and people don't run it for every single patch). So
it's an acceptable tradeoff.
There _is_ a better way to do it, which is to record the
position at which we find hashcmp(), and then check it
against the forbidden function list. Like:
@@
position p : script:python() { p[0].current_element != "oidcmp" };
expression E1,E2;
@@
- hashcmp@p(E1->hash, E2->hash)
+ oidcmp(E1, E2)
This is only a little slower than the current code, and does
the right thing in all cases. Unfortunately, not all builds
of Coccinelle include python support (including the ones in
Debian). Requiring it may mean that fewer people can easily
run the tool, which is worse than it simply being a little
slower.
We may want to revisit this decision in the future if:
- builds with python become more common
- we find more uses for python support that tip the
cost-benefit analysis
But for now this patch sticks with the angle-bracket
solution, and converts all existing cocci patches. This
fixes only one missed case in the current code, though it
makes a much better difference for some new rules I'm adding
(converting "!hashcmp()" to "hasheq()" misses over half the
possible conversions using the old form).

The append_signoff() function takes an "int" to specify the
number of bytes to ignore. Most callers just pass 0, and the
remainder use ignore_non_trailer() to skip over cruft.
That function also returns an int, and uses them internally.
On systems where size_t is larger than an int (i.e., most
64-bit systems), dealing with a ridiculously large commit
message could end up overflowing an int, producing
surprising results (e.g., returning a negative offset, which
would cause us to look outside the original string).
Let's consistently use size_t for these offsets through this
whole stack. As a bonus, this makes the meaning of
"ignore_footer" as an offset (and not a boolean) more clear.
But while we're here, let's also document the interface.

When the sequencer code appends a signoff or cherry-pick
origin, it uses the default trailer-parsing options, which
treat "---" as the end of the commit message. As a result,
it may be fooled by a commit message that contains that
string and fail to find the existing trailer block. Even
more confusing, the actual append code does not know about
"---", and always appends to the end of the string. This can
lead to bizarre results. E.g., appending a signoff to a
commit message like this:
subject
body
---
these dashes confuse the parser!
Signed-off-by: A
results in output with a final block like:
Signed-off-by: A
Signed-off-by: A
The parser thinks the final line of the message is "body",
and ignores everything else, claiming there are no trailers.
So we output an extra newline separator (wrong) and add a
duplicate signoff (also wrong).
Since we know we are feeding a pure commit message, we can
simply tell the parser to ignore the "---" divider.

Most of the trailer code has an "opts" struct which is
filled in by the caller. We don't pass it down to
trailer_info_get(), which does the initial parsing, because
there hasn't yet been a need to do so.
Let's start passing it down in preparation for adding new
options. Note that there's a single caller which doesn't
otherwise have such an options struct. Since it's just one
caller (that we'd have to modify anyway), let's not bother
with any special treatment like accepting a NULL options
struct, and just have it allocate one with the defaults.

We store the length of the trailers list in a size_t. So on
a 64-bit system with a 32-bit int, in the unlikely case that
we manage to actually allocate a list with 2^31 entries,
we'd loop forever trying to iterate over it (our "int" would
wrap to negative before exceeding info->trailer_nr).
This probably doesn't matter in practice. Each entry is at
least a pointer plus a non-empty string, so even without
malloc overhead or the memory to hold the original string
we're parsing from, you'd need to allocate tens of
gigabytes. But it's easy enough to do it right.

If a merge command in the todo list specifies just a branch to merge
with no -C/-c argument then item->commit is NULL. This means that if
there are merge conflicts error_with_patch() is passed a NULL commit
which causes a segmentation fault when make_patch() tries to look it up.
This commit implements a minimal fix which fixes the crash and allows
the user to successfully commit a conflict resolution with 'git rebase
--continue'. It does not write .git/rebase-merge/patch,
.git/rebase-merge/stopped-sha or update REBASE_HEAD. To sensibly get the
hashes of the merge parents would require refactoring do_merge() to
extract the code that parses the merge parents into a separate function
which error_with_patch() could then use to write the parents into the
stopped-sha file. To create meaningful output make_patch() and 'git
rebase --show-current-patch' would also need to be modified to diff the
merge parent and merge base in this case.

The idea of `--exec` is to append an `exec` call after each `pick`.
Since the introduction of fixup!/squash! commits, this idea was extended
to apply to "pick, possibly followed by a fixup/squash chain", i.e. an
exec would not be inserted between a `pick` and any of its corresponding
`fixup` or `squash` lines.
The current implementation uses a dirty trick to achieve that: it
assumes that there are only pick/fixup/squash commands, and then
*inserts* the `exec` lines before any `pick` but the first, and appends
a final one.
With the todo lists generated by `git rebase --rebase-merges`, this
simple implementation shows its problems: it produces the exact wrong
thing when there are `label`, `reset` and `merge` commands.
Let's change the implementation to do exactly what we want: look for
`pick` lines, skip any fixup/squash chains, and then insert the `exec`
line. Lather, rinse, repeat.
Note: we take pains to insert *before* comment lines whenever possible,
as empty commits are represented by commented-out pick lines (and we
want to insert a preceding pick's exec line *before* such a line, not
afterward).
While at it, also add `exec` lines after `merge` commands, because they
are similar in spirit to `pick` commands: they add new commits.

Single quotes should be escaped as \' not \\'. The bad quoting breaks
the interactive version of 'rebase --root' (which is used when there
is no '--onto' even if the user does not specify --interactive) for
authors that contain "'" as sq_dequote() called by read_author_ident()
errors out on the bad quoting.
For other interactive rebases this only affects external scripts that
read the author script and users whose git is upgraded from the shell
version of rebase -i while rebase was stopped when the author contains
"'". This is because the parsing in read_env_script() expected the
broken quoting.
This patch includes code to handle the broken quoting when
git has been upgraded while rebase was stopped. It does this by
detecting the missing "'" at the end of the GIT_AUTHOR_DATE line to see
if it should dequote \\' as "'". Note this is only implemented for
normal picks, not for creating a new root commit (rebase will stop with
an error complaining out bad quoting in that case).
The fallback code has been manually tested by reverting both the quoting
fixes in write_author_script() and the previous fix for the missing "'"
at the end of the GIT_AUTHOR_DATE line and running
t3404-rebase-interactive.sh.
Ideally rebase and am would share the same code for reading and
writing the author script, but this commit just fixes the immediate
bug.

read_author_ident() is careful to handle errors "gently" when parsing
"rebase-merge/author-script" by printing a suitable warning and
returning NULL; it never die()'s. One possible reason that parsing might
fail is that "rebase-merge/author-script" has been hand-edited in such a
way which corrupts it or the information it contains.
However, read_author_ident() invokes fmt_ident() which is not so careful
about failing "gently". It will die() if it encounters a malformed
timestamp. Since read_author_ident() doesn't want to die() and since
it's dealing with possibly hand-edited data, take care to avoid passing
a bogus timestamp to fmt_ident().
A more "correctly engineered" fix would be to add a "gentle" version of
fmt_ident(), however, such a change it outside the scope of the bug-fix
series. If fmt_ident() ever does grow a "gentle" cousin, then the manual
timestamp check added here can be retired.

When "git rebase -i --root" creates a new root commit, it corrupts the
"author" header's timestamp by prepending a "@":
author A U Thor <author@example.com> @1112912773 -0700
The commit parser is very strict about the format of the "author"
header, and does not allow a "@" in that position.
The "@" comes from GIT_AUTHOR_DATE in "rebase-merge/author-script",
signifying a Unix epoch-based timestamp, however, read_author_ident()
incorrectly allows it to slip into the commit's "author" header, thus
corrupting it.
One possible fix would be simply to filter out the "@" when constructing
the "author" header timestamp, however, a more correct fix is to parse
the GIT_AUTHOR_DATE date (via parse_date()) and format the parsed result
into the "author" header. Since "rebase-merge/author-script" may be
edited by the user, this approach has the extra benefit of catching
other potential timestamp corruption due to hand-editing.
We can do better than calling parse_date() ourselves and constructing
the "author" header manually, however, by instead taking advantage of
fmt_ident() which does this work for us.
The benefits of using fmt_ident() are twofold. First, it simplifies the
logic considerably by allowing us to avoid the complexity of building
the "author" header in parallel with and in the same buffer from which
"rebase-merge/author-script" is being parsed. Instead, fmt_ident() is
invoked to compose the header after parsing is complete.
Second, fmt_ident() is careful to prevent "crud" from polluting the
composed ident. As with validating GIT_AUTHOR_DATE, this "crud"
avoidance prevents other (possibly hand-edited) bogus author information
from "rebase-merge/author-script" from corrupting the commit object.

When "git rebase -i --root" creates a new root commit, it corrupts the
"author" header's timezone by repeating the last digit:
author A U Thor <author@example.com> @1112912773 -07000
This is due to two bugs.
First, write_author_script() neglects to add the closing quote to the
value of GIT_AUTHOR_DATE when generating "rebase-merge/author-script".
Second, although sq_dequote() correctly diagnoses the missing closing
quote, read_author_ident() ignores sq_dequote()'s return value and
blindly uses the result of the aborted dequote.
sq_dequote() performs dequoting in-place by removing quoting and
shifting content downward. When it detects misquoting (lack of closing
quote, in this case), it gives up and returns an error without inserting
a NUL-terminator at the end of the shifted content, which explains the
duplicated last digit in the timezone.
(Note that the "@" preceding the timestamp is a separate bug which
will be fixed subsequently.)

When "git rebase -i --root" creates a new root commit (say, by swapping
in a different commit for the root), it corrupts the commit's "author"
header with trailing garbage:
author A U Thor <author@example.com> @1112912773 -07000or@example.com
This is a result of read_author_ident() neglecting to NUL-terminate the
buffer into which it composes the "author" header.
(Note that the "@" preceding the timestamp and the extra "0" in the
timezone are separate bugs which will be fixed subsequently.)
Security considerations: Construction of the "author" header by
read_author_ident() happens in-place and in parallel with parsing the
content of "rebase-merge/author-script" which occupies the same buffer.
This is possible because the constructed "author" header is always
smaller than the content of "rebase-merge/author-script". Despite
neglecting to NUL-terminate the constructed "author" header, memory is
never accessed (either by read_author_ident() or its caller) beyond the
allocated buffer since a NUL-terminator is present at the end of the
loaded "rebase-merge/author-script" content, and additional NUL's are
inserted as part of the parsing process.

Many messages will be marked for translation in the following
commits. This commit updates some of them to be more consistent and
reduce diff noise in those commits. Changes are
- keep the first letter of die(), error() and warning() in lowercase
- no full stop in die(), error() or warning() if it's single sentence
messages
- indentation
- some messages are turned to BUG(), or prefixed with "BUG:" and will
not be marked for i18n
- some messages are improved to give more information
- some messages are broken down by sentence to be i18n friendly
(on the same token, combine multiple warning() into one big string)
- the trailing \n is converted to printf_ln if possible, or deleted
if not redundant
- errno_errno() is used instead of explicit strerror()

The sequencer currently passes GIT_DIR, but not GIT_WORK_TREE, to exec
commands. In that configuration, we assume that whatever directory
we're in is the top level of the work tree, and git rev-parse
--show-toplevel responds accordingly. However, when we're in a
subdirectory, that isn't correct: we respond with the subdirectory as
the top level, resulting in unexpected behavior.
Ensure that we pass GIT_WORK_TREE as well as GIT_DIR so that git
operations within subdirectories work correctly.
Note that we are guaranteed to have a work tree in this case: the
relevant sequencer functions are called only from revert, cherry-pick,
and rebase--helper; all of these commands require a working tree.

Use the configured comment character when generating comments about
branches in a todo list. Failure to honor this configuration causes a
failure to parse the resulting todo list.
Setting core.commentChar to "auto" will not be honored here, and the
previously configured or default value will be used instead. But, since
the todo list will consist of only generated content, there should not
be any non-comment lines beginning with that character.

Previously, we introduced the `merge` command for use in todo lists,
to allow to recreate and modify branch topology.
For ease of implementation, and to make review easier, the initial
implementation only supported merge commits with exactly two parents.
This patch adds support for octopus merges, making use of the
just-introduced `-F <file>` option for the `git merge` command: to keep
things simple, we spawn a new Git command instead of trying to call a
library function, also opening an easier door to enhance `rebase
--rebase-merges` to optionally use a merge strategy different from
`recursive` for regular merges: this feature would use the same code
path as octopus merges and simply spawn a `git merge`.

When cherry-picking a single commit, we go through a special
code path that avoids creating a sequencer todo list at all.
This path expects our revision parsing to turn up exactly
one commit, and dies with a BUG if it doesn't.
But it's actually quite easy to fool. For example:
$ git cherry-pick --author=no.such.person HEAD
error: BUG: expected exactly one commit from walk
fatal: cherry-pick failed
This isn't a bug; it's just bogus input.
The condition to trigger this message actually has two
parts:
1. We saw no commits. That's the case in the example
above. Let's drop the "BUG" here to make it clear that
the input is the problem. And let's also use the phrase
"empty commit set passed", which matches what we say
when we do a real revision walk and it turns up empty.
2. We saw more than one commit. That one _should_ be
impossible to trigger, since we fed at most one tip and
provided the no_walk option (and we'll have already
expanded options like "--branches" that can turn into
multiple tips). If this ever triggers, it's an
indication that the conditional added by 7acaaac275
(revert: allow single-pick in the middle of cherry-pick
sequence, 2011-12-10) needs to more carefully define
the single-pick case.
So this can remain a bug, but we'll upgrade it to use
the BUG() macro, which would make it easier to detect
and analyze if it does trigger.

If the user gives us a set that prepare_revision_walk()
takes to be empty, like:
git cherry-pick base..base
then we report an error. It's nonsense, and there's nothing
to pick.
But if they use revision options that later cull the list,
like:
git cherry-pick --author=nobody base~2..base
then we quietly create an empty todo list and return
success.
Arguably either behavior is acceptable, but we should
definitely be consistent about it. Reporting an error
seems to match the original intent, which dates all the way
back to 7e2bfd3f99 (revert: allow cherry-picking more than
one commit, 2010-06-02). That in turn was trying to match
the single-commit case that existed before then (and which
continues to issue an error).

Add a repository argument to allow callers of lookup_commit to be more
specific about which repository to handle. This is a small mechanical
change; it doesn't change the implementation to handle repositories
other than the_repository yet.
As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.
