Jonathan Nieder 67a612c4e5 test: remove a porcelain test that hard-codes commit names
The rev-list output in this test depends on the details of test_tick's
dummy dates and the choice of hash function.  Worse, it depends on the
order and nature of commits made in the earlier tests, so adding new
tests or rearranging existing ones breaks it.

It would be nice to check that "git commit" and commit-tree name
objects consistently and that commit objects' text is as documented,
but this particular test checks everything at once and hence is not a
robust test for that.  Remove it.

Jens Lehmann 6a5cedac87 diff/status: print submodule path when looking for changes fails
diff and status run "git status --porcelain" inside each populated
submodule to see if it contains changes (unless told not to do so via
config or command line option). When that fails, e.g. due to a corrupt
submodule .git directory, it just prints "git status --porcelain failed"
or "Could not run git status --porcelain" without giving the user a clue
where that happened.

Add '"in submodule %s", path' to these error strings to tell the user
where exactly the problem occurred.

Thomas Rast 6c52ec8a9a reset: update cache-tree data when appropriate
In the case of --mixed and --hard, we throw away the old index and
rebuild everything from the tree argument (or HEAD).  So we have an

Thomas Rast 11c8a74a64 commit: write cache-tree data when writing index anyway
In prepare_index(), we refresh the index, and then write it to disk if
this changed the index data.  After running hooks we re-read the index
and compute the root tree sha1 with the cache-tree machinery.

This gives us a mostly free opportunity to write up-to-date cache-tree
data: we can compute it in prepare_index() immediately before writing
the index to disk.

If we do this, we were going to write the index anyway, and the later
cache-tree update has no further work to do.  If we don't do it, we
don't do any extra work, though we still don't have have cache-tree
data after the commit.

The only case that suffers badly is when the pre-commit hook changes
many trees in the index.  I'm writing this off as highly unusual.

Thomas Rast 4eb0346fb8 Test the current state of the cache-tree optimization
The cache-tree optimization originally helped speed up write-tree
operation.  However, many commands no longer properly maintain -- or
use an opportunity to cheaply generate -- the cache-tree data.  In
particular, this affects commit, checkout and reset.  The notable
examples that *do* write cache-tree data are read-tree and write-tree.

This sadly means most people no longer benefit from the optimization,
as they would not normally use the plumbing commands.

Document the current state of affairs in a test file, in preparation
for improvements in the area.

Ævar Arnfjörð Bjarmason 5e9637c629 i18n: add infrastructure for translating Git with gettext
Change the skeleton implementation of i18n in Git to one that can show
localized strings to users for our C, Shell and Perl programs using
either GNU libintl or the Solaris gettext implementation.

This new internationalization support is enabled by default. If
gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, Git falls back on its current behavior of
showing interface messages in English. When using the autoconf script
we'll auto-detect if the gettext libraries are installed and act
appropriately.

This change is somewhat large because as well as adding a C, Shell and
Perl i18n interface we're adding a lot of tests for them, and for
those tests to work we need a skeleton PO file to actually test
translations. A minimal Icelandic translation is included for this
purpose. Icelandic includes multi-byte characters which makes it easy
to test various edge cases, and it's a language I happen to
understand.

The rest of the commit message goes into detail about various
sub-parts of this commit.

= Installation

Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that, but that's only intended to be used to test Git itself.

= Perl

Perl code that's to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by default.

Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.

Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.

I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.

See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for
a further elaboration on this topic.

= Shell

Shell code that's to be localized should use the git-sh-i18n
library. It's basically just a wrapper for the system's gettext.sh.

If gettext.sh isn't available we'll fall back on gettext(1) if it's
available. The latter is available without the former on Solaris,
which has its own non-GNU gettext implementation. We also need to
emulate eval_gettext() there.

If neither are present we'll use a dumb printf(1) fall-through
wrapper.

= About libcharset.h and langinfo.h

We use libcharset to query the character set of the current locale if
it's available. I.e. we'll use it instead of nl_langinfo if
HAVE_LIBCHARSET_H is set.

The GNU gettext manual recommends using langinfo.h's
nl_langinfo(CODESET) to acquire the current character set, but on
systems that have libcharset.h's locale_charset() using the latter is
either saner, or the only option on those systems.

GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either,
but MinGW and some others need to use libcharset.h's locale_charset()
instead.

=Credits

Nguyễn Thái Ngọc Duy d5a35c114a Copy resolve_ref() return value for longer use
resolve_ref() may return a pointer to a static buffer. Callers that
use this value longer than a couple of statements should copy the
value to avoid some hidden resolve_ref() call that may change the
static buffer's value.

The bug found by Tony Wang <wwwjfy@gmail.com> in builtin/merge.c
demonstrates this. The first call is in cmd_merge()

branch = resolve_ref("HEAD", head_sha1, 0, &flag);

Then deep in lookup_commit_or_die() a few lines after, resolve_ref()
may be called again and destroy "branch".

Brandon Casey cc64b318f2 builtin/apply.c: report error on failure to recognize input
When git apply is passed something that is not a patch, it does not produce
an error message or exit with a non-zero status if it was not actually
"applying" the patch i.e. --check or --numstat etc were supplied on the
command line.

Fix this by producing an error when apply fails to find any hunks whatsoever
while parsing the patch.

This will cause some of the output formats (--numstat, --diffstat, etc) to
produce an error when they formerly would have reported zero changes and
exited successfully.  That seems like the correct behavior though.  Failure
to recognize the input as a patch should be an error.

Plus, add a test.

It is useful to be able to rewind a check-summed file to a certain
previous state after writing data into it using sha1write() API. The
fast-import command does this after streaming a blob data to the packfile
being generated and then noticing that the same blob has already been
written, and it does this with a private code truncate_pack() that is
commented as "Yes, this is a layering violation".

Introduce two API functions, sha1file_checkpoint(), that allows the caller
to save a state of a sha1file, and then later revert it to the saved state.
Use it to reimplement truncate_pack().

Johan Herland 1838685780 fast-import: Fix incorrect fanout level when modifying existing notes refs
This fixes the bug uncovered by the tests added in the previous two patches.

When an existing notes ref was loaded into the fast-import machinery, the
num_notes counter associated with that ref remained == 0, even though the
true number of notes in the loaded ref was higher. This caused a fanout
level of 0 to be used, although the actual fanout of the tree could be > 0.
Manipulating the notes tree at an incorrect fanout level causes removals to
silently fail, and modifications of existing notes to instead produce an
additional note (leaving the old object in place at a different fanout level).

This patch fixes the bug by explicitly counting the number of notes in the
notes tree whenever it looks like the num_notes counter could be wrong (when
num_notes == 0). There may be false positives (i.e. triggering the counting
when the notes tree is truly empty), but in those cases, the counting should
not take long.

Johan Herland 9ff5e21f0e t9301: Add 2nd testcase exposing bugs in fast-import's notes fanout handling
The previous patch exposed a bug in fast-import where _removing_ an existing
note fails (when that note resides on a non-zero fanout level, and was added
prior to this fast-import run).

This patch demostrates the same issue when _changing_ an existing note
(subject to the same circumstances).

Johan Herland d1075414dc t9301: Fix testcase covering up a bug in fast-import's notes fanout handling
There is a bug in fast-import where the fanout levels of an existing notes
tree being loaded into the fast-import machinery is disregarded. Instead, any
tree loaded is assumed to have a fanout level of 0. If the true fanout level
is deeper, any attempt to remove a note from that tree will silently fail
(as the note will not be found at fanout level 0).

However, this bug was covered up by the way in which the t9301 testcase was
written: When generating the fast-import commands to test mass removal of
notes, we appended these commands to an already existing 'input' file which
happened to already contain the fast-import commands used in the previous
subtest to generate the very same notes tree. This would normally be harmless
(but suboptimal) as the notes created were identical to the notes already
present in the notes tree. But the act of repeating all the notes additions
caused the internal fast-import data structures to recalculate the fanout,
instead of hanging on to the initial (incorrect) fanout (that causes the bug
described above). Thus, the subsequent removal of notes in the same 'input'
file would succeed, thereby covering up the bug described above.

This patch creates a new 'input' file instead of appending to the file from
the previous subtest. Thus, we end up properly testing removal of notes that
were added by a previous fast-import command. As a side effect, the notes
removal can no longer refer to commits using the marks set by the previous
fast-import run, instead the commits names must be referenced directly.

The underlying fast-import bug is still present after this patch, but now we
have at least uncovered it. Therefore, the affected subtests are labeled as
expected failures until the underlying bug is fixed.
