Fix configuration codepath to pay proper attention to commondir
that is used in multi-worktree situation, and isolate config API
into its own header file.
* bw/config-h:
config: don't implicitly use gitdir or commondir
config: respect commondir
setup: teach discover_git_directory to respect the commondir
config: don't include config.h by default
config: remove git_config_iter
config: create config.h
|

Stop including config.h by default in cache.h. Instead only include
config.h in those files which require use of the config system.

Update the C style recommendation for notes for translators, as
recent versions of gettext tools can work with our style of
multi-line comments.
* ab/c-translators-comment-style:
C style: use standard style for "TRANSLATORS" comments
|
|
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
struct object_id arguments.
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.
parse_object_buffer will lose this temporary in a later patch.

Git's source code assumes that unsigned long is at least as precise as
time_t. Which is incorrect, and causes a lot of problems, in particular
where unsigned long is only 32-bit (notably on Windows, even in 64-bit
versions).
So let's just use a more appropriate data type instead. In preparation
for this, we introduce the new `timestamp_t` data type.
By necessity, this is a very, very large patch, as it has to replace all
timestamps' data type in one go.
As we will use a data type that is not necessarily identical to `time_t`,
we need to be very careful to use `time_t` whenever we interact with the
system functions, and `timestamp_t` everywhere else.

Currently, Git's source code treats all timestamps as if they were
unsigned longs. Therefore, it is okay to write "%lu" when printing them.
There is a substantial problem with that, though: at least on Windows,
time_t is *larger* than unsigned long, and hence we will want to switch
away from the ill-specified `unsigned long` data type.
So let's introduce the pseudo format "PRItime" (currently simply being
defined to "lu") to make it easier to change the data type used for
timestamps.

Since we will likely be introducing a new hash function at some point,
and that hash function might be longer than 40 hex characters, use the
constant GIT_MAX_HEXSZ, which is designed to be suitable for
allocations, instead of GIT_SHA1_HEXSZ. This will ease the transition
down the line by distinguishing between places where we need to allocate
memory suitable for the largest hash from those where we need to handle
the current hash.

"git blame --porcelain" misidentified the "previous" <commit, path>
pair (aka "source") when contents came from two or more files.
* jk/blame-fixes:
blame: output porcelain "previous" header for each file
blame: handle --no-abbrev
blame: fix alignment with --abbrev=40
|
|
It's possible for content currently found in one file to
have originated in two separate files, each of which may
have been modified in some single older commit. The
--porcelain output generates an incorrect "previous" header
in this case, whereas --line-porcelain gets it right. The
problem is that the porcelain output tries to omit repeated
details of commits, and treats "previous" as a property of
the commit, when it is really a property of the blamed block
of lines.
Let's look at an example. In a case like this, you might see
this output from --line-porcelain:
SOME_SHA1 1 1 1
author ...
committer ...
previous SOME_SHA1^ file_one
filename file_one
...some line content...
SOME_SHA1 2 1 1
author ...
committer ...
previous SOME_SHA1^ file_two
filename file_two
...some different content....
The "filename" fields tell us that the two lines are from
two different files. But notice that the filename also
appears in the "previous" field, which tells us where to
start a re-blame. The second content line never appeared in
file_one at all, so we would obviously need to re-blame from
file_two (or possibly even some other file, if had just been
renamed to file_two in SOME_SHA1).
So far so good. Now here's what --porcelain looks like:
SOME_SHA1 1 1 1
author ...
committer ...
previous SOME_SHA1^ file_one
filename file_one
...some line content...
SOME_SHA1 2 1 1
filename file_two
...some different content....
We've dropped the author and committer fields from the
second line, as they would just be repeats. But we can't
omit "filename", because it depends on the actual block of
blamed lines, not just the commit. This is handled by
emit_porcelain_details(), which will show the filename
either if it is the first mention of the commit _or_ if the
commit has multiple paths in it.
But we don't give "previous" the same handling. It's written
inside emit_one_suspect_detail(), which bails early if we've
already seen that commit. And so the output above is wrong;
a reader would assume that the correct place to re-blame
line two is from file_one, but that's obviously nonsense.
Let's treat "previous" the same as "filename", and show it
fresh whenever we know we are in a confusing case like this.

You can already ask blame for full sha1s with "-l" or with
"--abbrev=40". But for consistency with other parts of Git,
we should support "--no-abbrev".
Worse, blame already accepts --no-abbrev, but it's totally
broken. When we see --no-abbrev, the abbrev variable is set
to 0, which is then used as a printf precision. For regular
sha1s, that means we print nothing at all (which is very
wrong). For boundary commits we decrement it to "-1", which
printf interprets as "no limit" (which is almost correct,
except it misses the 39-length magic explained in the
previous commit).
Let's detect --no-abbrev and behave as if --abbrev=40 was
given.

The blame command internally adds 1 to any requested sha1
abbreviation length, and then subtracts it when outputting a
boundary commit. This lets regular and boundary sha1s line
up visually, but it misses one corner case.
When the requested length is 40, we bump the value to 41.
But since we only have 40 characters, that's all we can show
(fortunately the truncation is done by a printf precision
field, so it never tries to read past the end of the
buffer). So a normal sha1 shows 40 hex characters, and a
boundary sha1 shows "^" plus 40 hex characters. The result
is misaligned.
The "-l" option to show long sha1s gets around this by
skipping the "abbrev" variable entirely and just always
using GIT_SHA1_HEXSZ. This avoids the "+1" issue, but it
does mean that boundary commits only have 39 characters
printed. This is somewhat odd, but it does look good
visually: the results are aligned and left-justified. The
alternative would be to allocate an extra column that would
contain either an extra space or the "^" boundary marker.
As this is by definition the human-readable view, it's
probably not that big a deal either way (and of course
--porcelain, etc, correctly produce correct 40-hex sha1s).
But for consistency, this patch teaches --abbrev=40 to
produce the same output as "-l" (always left-aligned, with
40-hex for normal sha1s, and "^" plus 39-hex for
boundaries).
