Change all the "TRANSLATORS: [...]" comments in the C code to use the
regular Git coding style, and amend the style guide so that the
example there uses that style.
This custom style was necessary back in 2010 when the gettext support
was initially added, and was subsequently documented in commit
cbcfd4e3ea ("i18n: mention "TRANSLATORS:" marker in
Documentation/CodingGuidelines", 2014-04-18).
GNU xgettext hasn't had the parsing limitation that necessitated this
exception for almost 3 years. Since its 0.19 release on 2014-06-02
it's been able to recognize TRANSLATOR comments in the standard Git
comment syntax[1].
Usually we'd like to keep compatibility with software that's that
young, but in this case literally the only person who needs to be
using a gettext newer than 3 years old is Jiang Xin (the only person
who runs & commits "make pot" results), so I think in this case we can
make an exception.
This xgettext parsing feature was added after a thread on the Git
mailing list[2] which continued on the bug-gettext[3] list, but we
never subsequently changed our style & styleguide, do so.
There are already longstanding changes in git that use the standard
comment style & have their TRANSLATORS comments extracted properly
without getting the literal "*"'s mixed up in the text, as would
happen before xgettext 0.19.
Commit 7ff2683253 ("builtin-am: implement -i/--interactive",
2015-08-04) added one such comment, which in commit df0617bfa7 ("l10n:
git.pot: v2.6.0 round 1 (123 new, 41 removed)", 2015-09-05) got picked
up in the po/git.pot file with the right format, showing that Jiang
already runs a modern xgettext.
The xgettext parser does not handle the sort of non-standard comment
style that I'm amending here in sequencer.c, but that isn't standard
Git comment syntax anyway. With this change to sequencer.c & "make
pot" the comment in the pot file is now correct:
#. TRANSLATORS: %s will be "revert", "cherry-pick" or
-#. * "rebase -i".
+#. "rebase -i".

Convert lookup_commit, lookup_commit_or_die,
lookup_commit_reference, and lookup_commit_reference_gently to take

Introduce a temporary in parse_object buffer in order to convert this
function. This is required since in order to convert parse_object and
parse_object_buffer, lookup_commit_reference_gently and
lookup_commit_or_die would need to be converted. Not introducing a
temporary would therefore require that lookup_commit_or_die take a
struct object_id *, but lookup_commit would take unsigned char *,
leaving a confusing and hard-to-use interface.

We'd prefer to avoid unchecked snprintf calls because
truncation can lead to unexpected results.
These are all cases where truncation shouldn't ever happen,
because the input to snprintf is fixed in size. That makes
them candidates for xsnprintf(), but it's simpler still to
just use the heap, and then nobody has to wonder if "100" is
big enough.
We'll use xstrfmt() where possible, and a strbuf when we need
the resulting size or to reuse the same buffer in a loop.

When the current branch is renamed with 'git branch -m/-M' or deleted
with 'git update-ref -m<msg> -d', the event is recorded in HEAD's log
with an empty message. In preparation for adding a more meaningful
message to HEAD's log in these cases, update delete_ref() to take a
message argument and pass it along to ref_transaction_delete().
Modify all callers to pass NULL for the new message argument; no
change in behavior is intended.
Note that this is relevant for HEAD's log but not for the deleted
ref's log, which is currently deleted along with the ref. Even if it
were not, an entry for the deletion wouldn't be present in the deleted
ref's log. files_transaction_commit() writes to the log if
REF_NEEDS_COMMIT or REF_LOG_ONLY are set, but lock_ref_for_update()
doesn't set REF_NEEDS_COMMIT for the deleted ref because REF_DELETING
is set. In contrast, the update for HEAD has REF_LOG_ONLY set by
split_head_update(), resulting in the deletion being logged.

strbuf: introduce strbuf_getline_{lf,nul}()

Create a new expansion function, expand_loose_notes_ref which will first
check whether the ref can be found using get_sha1. If it can't be found
then it will fallback to using expand_notes_ref. The content of the
strbuf will not be changed if the notes ref can be located using
get_sha1. Otherwise, it may be updated as done by expand_notes_ref.
Since we now support merging from non-notes refs, remove the test case
associated with that behavior. Add a test case for merging from a

The strbuf_getline() interface allows a byte other than LF or NUL as
the line terminator, but this is only because I wrote these
codepaths anticipating that there might be a value other than NUL
and LF that could be useful when I introduced line_termination long
time ago. No useful caller that uses other value has emerged.
By now, it is clear that the interface is overly broad without a
good reason. Many codepaths have hardcoded preference to read
either LF terminated or NUL terminated records from their input, and
then call strbuf_getline() with LF or NUL as the third parameter.
This step introduces two thin wrappers around strbuf_getline(),
namely, strbuf_getline_lf() and strbuf_getline_nul(), and
mechanically rewrites these call sites to call either one of
them. The changes contained in this patch are:
* introduction of these two functions in strbuf.[ch]
* mechanical conversion of all callers to strbuf_getline() with
either '\n' or '\0' as the third parameter to instead call the
respective thin wrapper.
After this step, output from "git grep 'strbuf_getline('" would
become a lot smaller. An interim goal of this series is to make
this an empty set, so that we can have strbuf_getline_crlf() take
over the shorter name strbuf_getline().

init_notes() is the main point of entry to the notes API. It ensures
that the input can be used as ref, because it needs a ref to update to
store notes tree after modifying it.
There however are many use cases where notes tree is only read, e.g.
"git log --notes=...". Any notes-shaped treeish could be used for such
purpose, but it is not allowed due to existing restriction.
Allow treeish expressions to be used in the case the notes tree is going
to be used without write "permissions". Add a flag to distinguish
whether the notes tree is intended to be used read-only, or will be
updated.
With this change, operations that use notes read-only can be fed any
notes-shaped tree-ish can be used, e.g. git log --notes=notes@{1}.

* tk/stripspace:
stripspace: use parse-options for command-line parsing
strbuf: make stripspace() part of strbuf

makes sense to have it in a more generic place. Since it operates
on an strbuf and the function is declared in strbuf.h, move it to
strbuf.c and add the corresponding prefix to its name, just like
other API functions in the strbuf_* family.

create_note() has a non-trivial interface, and comprises three loosely
related parts:
1. launching the editor with the note contents, if needed
2. appending to an existing note, if append_only was given
3. adding or removing the resulting note, based on whether it's non-empty
Split it along those lines to make the logic clearer: The first part
goes into a new function - prepare_note_data(), with a simpler interface.
The second part is moved into append_edit(), which is the only user of
this code. Finally, the add vs. remove decision is moved into the callers
(add() and append_edit()), keeping the logic for writing the actual note
object in a separate function: write_note_data().

Currently "git notes add -C $object" will read the raw bytes from $object,
and then copy those bytes into the note object, which is hardcoded to be
of type blob. This means that if the given $object is a non-blob (e.g.
tree or commit), the raw bytes from that object is copied into a blob
object. This is probably not useful, and certainly not what any sane
user would expect. So disallow it, by erroring out if the $object passed
to the -C option is not a blob.
The fix also applies to the -c option (in which the user is prompted to
edit/verify the note contents in a text editor), and also when -c/-C is
passed to "git notes append" (which appends the $object contents to an
existing note object). In both cases, passing a non-blob $object does not
make sense.
Also add a couple of tests demonstrating expected behavior.

This is a pure code movement of the machinery for copying notes to
rewritten objects. This code was located in builtin/notes.c for
historical reasons. In order to make it available to builtin/commit.c
it was declared in builtin.h. This was more of an accident of history
than a concious design, and we now want to make this machinery more
widely available.
Hence, this patch moves the code into the new notes-utils.[hc] files
which are included into libgit.a. Except for adjusting #includes
accordingly, this patch merely moves the relevant functions verbatim
into the new files.

When copying notes for a rewritten object, the resulting notes commit
would have the following hardcoded commit message:
Notes added by 'git notes copy'
This is obviously bogus when the notes rewriting is performed by
'git commit --amend'.
Therefore, let the caller specify an appropriate notes commit message
instead of hardcoding it. The above message is used for 'git notes copy',
but when calling finish_copy_notes_for_rewrite() from builtin/commit.c,
we use the following message instead:
Notes added by 'git commit --amend'

Some users do want to write a line that begin with a pound sign, #,
in their commit log message. Many tracking system recognise
a token of #<bugid> form, for example.
The support we offer these use cases is not very friendly to the end
users. They have a choice between
- Don't do it. Avoid such a line by rewrapping or indenting; and
- Use --cleanup=whitespace but remove all the hint lines we add.
Give them a way to set a custom comment char, e.g.
$ git -c core.commentchar="%" commit
so that they do not have to do either of the two workarounds.

resolve_ref() may return a pointer to a static buffer. Callers that

Signed-off-by: Junio C Hamano <gitster@pobox.com>
Depending on the application, it is not necessarily an error for an object
to lack a note, especially if the only thing the caller wants to make sure
is that notes are cleared for an object. By passing this option from the
command line, the "git notes remove" command considers it a success if the
object did not have any note to begin with.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
While "xargs -n1 git notes rm" is certainly a possible way to remove notes
from many objects, this would create one notes "commit" per removal, which
is not quite suitable for seasonal housekeeping.
Allow taking more than one on the command line, and record their removal
as a single atomic event if everthing goes well.
Even though the old code insisted that "git notes rm" must be given only
one object (or zero, in which case it would default to HEAD), this
condition was not tested. Add tests to handle the new case where we feed
multiple objects, and also make sure if there is a bad input, no change
is recorded.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
Currently, "notes add" (without -f/--force) will abort when the given object
already has existing notes. This makes sense for the modes of "git notes add"
that would necessarily overwrite the old message (when using the -m/-F/-C/-c
options). However, when no options are given (meaning the notes are created
from scratch in the editor) it is not very user-friendly to abort on existing
notes, and forcing the user to run "git notes edit".
Instead, it is better to simply "redirect" to "git notes edit" automatically,
i.e. open the existing notes in the editor and let the user edit them.
This patch does just that.
This changes the behavior of "git notes add" without options when notes
already exist for the given object, but I doubt that many users really depend
on the previous failure from "git notes add" in this case.

This new strategy is similar to "concatenate", but in addition to
concatenating the two note candidates, this strategy sorts the resulting
lines, and removes duplicate lines from the result. This is equivalent to
applying the "cat | sort | uniq" shell pipeline to the two note candidates.
This strategy is useful if the notes follow a line-based format where one
wants to avoid duplicate lines in the merge result.
Note that if either of the note candidates contain duplicate lines _prior_
to the merge, these will also be removed by this merge strategy.
The patch also contains tests and documentation for the new strategy.

When manually resolving a notes merge, if the merging ref has moved since
the merge started, we should fail to complete the merge, and alert the user
to what's going on.
This situation may arise if you start a 'git notes merge' which results in
conflicts, and you then update the current notes ref (using for example
'git notes add/copy/amend/edit/remove/prune', 'git update-ref', etc.),
before you get around to resolving the notes conflicts and calling
'git notes merge --commit'.
We detect this situation by comparing the first parent of the partial merge
commit (which was created when the merge started) to the current value of the
merging notes ref (pointed to by the .git/NOTES_MERGE_REF symref).
If we don't fail in this situation, the notes merge commit would overwrite
the updated notes ref, thus losing the changes that happened in the meantime.
The patch includes a testcase verifying that we fail correctly in this
situation.

When the notes merge conflicts in .git/NOTES_MERGE_WORKTREE have been
resolved, we need to record a new notes commit on the appropriate notes
ref with the resolved notes.
This patch implements 'git notes merge --commit' which the user should
run after resolving conflicts in the notes merge worktree. This command
finalizes the notes merge by recombining the partial notes tree from
part 1 with the now-resolved conflicts in the notes merge worktree in a
merge commit, and updating the appropriate ref to this merge commit.
In order to correctly finalize the merge, we need to keep track of three
things:
- The partial merge result from part 1, containing the auto-merged notes.
This is now stored into a ref called .git/NOTES_MERGE_PARTIAL.
- The unmerged notes. These are already stored in
.git/NOTES_MERGE_WORKTREE, thanks to part 1.
- The notes ref to be updated by the finalized merge result. This is now
stored in a symref called .git/NOTES_MERGE_REF.
In addition to "git notes merge --commit", which uses the above details
to create the finalized notes merge commit, this patch also implements
"git notes merge --reset", which aborts the ongoing notes merge by simply
removing the files/directory described above.
FTR, "git notes merge --commit" reuses "git notes merge --reset" to remove
the information described above (.git/NOTES_MERGE_*) after the notes merge
have been successfully finalized.
The patch also contains documentation and testcases for the two new options.

Conflicts (that are to be resolved manually) are written into a special-
purpose working tree, located at .git/NOTES_MERGE_WORKTREE. Within this
directory, conflicting notes entries are stored (with conflict markers
produced by ll_merge()) using the SHA1 of the annotated object. The
.git/NOTES_MERGE_WORKTREE directory will only contain the _conflicting_
note entries. The non-conflicting note entries (aka. the partial merge
result) are stored in 'local_tree', and the SHA1 of the resulting commit
is written to 'result_sha1'. The return value from notes_merge() is -1.
The user is told to edit the files within the .git/NOTES_MERGE_WORKTREE
directory in order to resolve the conflicts.
The patch also contains documentation and testcases for the correct setup
of .git/NOTES_MERGE_WORKTREE.
The next part will recombine the partial notes merge result with the
resolved conflicts in .git/NOTES_MERGE_WORKTREE to produce the complete
merge result.

The new -s/--strategy command-line option to 'git notes merge' allow the user
to choose how notes merge conflicts should be resolved. There are four valid
strategies to choose from:
1. "manual" (the default): This will let the user manually resolve conflicts.
This option currently fails with an error message. It will be implemented
properly in future patches.
2. "ours": This automatically chooses the local version of a conflict, and
discards the remote version.
3. "theirs": This automatically chooses the remote version of a conflict, and
discards the local version.
4. "union": This automatically resolves the conflict by appending the remote
version to the local version.
The strategies are implemented using the combine_notes_* functions from the
notes.h API.
The patch also includes testcases verifying the correct implementation of
these strategies.

This continuation of the 'git notes merge' implementation teaches notes-merge
to properly do real merges between notes trees: Two diffs are performed, one
from $base to $remote, and another from $base to $local. The paths in each
diff are normalized to SHA1 object names. The two diffs are then consolidated
into a single list of change pairs to be evaluated. Each change pair consist
of:
- The annotated object's SHA1
- The $base SHA1 (i.e. the common ancestor notes for this object)
- The $local SHA1 (i.e. the current notes for this object)
- The $remote SHA1 (i.e. the to-be-merged notes for this object)
From the pair ($base -> $local, $base -> $remote), we can determine the merge
result using regular 3-way rules. If conflicts are encountered in this
process, we fail loudly and exit (conflict handling to be added in a future
patch), If we can complete the merge without conflicts, the resulting
notes tree is committed, and the current notes ref updated.
The patch includes added testcases verifying that we can successfully do real
conflict-less merges.

The combine_notes_fn functions uses a non-zero return value to indicate
failure. However, this return value was converted to a call to die()
in note_tree_insert().
Instead, propagate this return value out to add_note(), and return it
from there to enable the caller to handle errors appropriately.
Existing add_note() callers are updated to die() upon failure, thus
preserving the current behaviour. The only exceptions are copy_note()
and notes_cache_put() where we are able to propagate the add_note()
return value instead.
