Since 003c84f6d (specifying ranges: we did not mean to make
".." an empty set, 2011-05-02), we treat the argument ".."
specially. We detect it by noticing that both sides of the
range are empty, and that this is a non-symmetric two-dot
range.
While correct, this makes the code overly complicated. We
can just detect ".." up front before we try to do further
parsing. This avoids having to de-munge the NUL from dotdot,
and lets us eliminate an extra const array (which we needed
only to do direct pointer comparisons).
It also removes the one code path from the range-parsing
conditional that requires us to return -1. That will make it
simpler to pull the dotdot parsing out into its own
function.

The handle_revision_arg() function has a "dotdot" variable
that it uses to find a ".." or "..." in the argument. If we
don't find one, we look for other marks, like "^!". But we
just keep re-using the "dotdot" variable, which is
confusing.
Let's introduce a separate "mark" variable that can be used
for these other marks. They still reuse the same variable,
but at least the name is no longer actively misleading.

The "dotdot" range parser avoids calling
lookup_commit_reference() if we are directly fed two
commits. But its casts are unnecessarily complex; that
function will just return a commit we pass into it.
Just calling the function all the time is much simpler, and
doesn't do any significant extra work (the object is already
parsed, and deref_tag() on a non-tag is a noop; we do incur
one extra lookup_object() call, but that's fairly trivial).

When we are parsing a range like "a..b", we write a
temporary NUL over the first ".", so that we can access the
names "a" and "b" as C strings. But our restoration of the
original "." is done at inconsistent times, which can lead
to confusing results.
For most calls, we restore the "." after we resolve the
names, but before we call verify_non_filename(). This means
that when we later call add_pending_object(), the name for
the left-hand "a" has been re-expanded to "a..b". You can
see this with:
git log --source a...b
where "b" will be correctly marked with "b", but "a" will be
marked with "a...b". Likewise with "a..b" (though you need
to use --boundary to even see "a" at all in that case).
To top off the confusion, when the REVARG_CANNOT_BE_FILENAME
flag is set, we skip the non-filename check, and leave the
NUL in place.
That means we do report the correct name for "a" in the
pending array. But some code paths try to show the whole
"a...b" name in error messages, and these erroneously show
only "a" instead of "a...b". E.g.:
$ git cherry-pick HEAD:foo...HEAD:foo
error: object d95f3ad14dee633a758d2e331151e950dd13e4ed is a blob, not a commit
error: object d95f3ad14dee633a758d2e331151e950dd13e4ed is a blob, not a commit
fatal: Invalid symmetric difference expression HEAD:foo
(That last message should be "HEAD:foo...HEAD:foo"; I used
cherry-pick because it passes the CANNOT_BE_FILENAME flag).
As an interesting side note, cherry-pick actually looks at
and re-resolves the arguments from the pending->name fields.
So it would have been visibly broken by the first bug, but
the effect was canceled out by the second one.
This patch makes the whole function consistent by re-writing
the NUL immediately after calling verify_non_filename(), and
then restoring the "." as appropriate in some error-printing
and early-return code paths.

There is an implicit assumption that a directory containing only
untracked and ignored paths should itself be considered untracked. This
makes sense in use cases where we're asking if a directory should be
added to the git database, but not when we're asking if a directory can
be safely removed from the working tree; as a result, clean -d would
assume that an "untracked" directory containing ignored paths could be
deleted, even though doing so would also remove the ignored paths.
To get around this, we teach clean -d to collect ignored paths and skip
an untracked directory if it contained an ignored path, instead just
removing the untracked contents thereof. To achieve this, cmd_clean()
has to collect all untracked contents of untracked directories, in
addition to all ignored paths, to determine which untracked dirs must be
skipped (because they contain ignored paths) and which ones should *not*
be skipped.
For this purpose, correct_untracked_entries() is introduced to prune a
given dir_struct of untracked entries containing ignored paths and those
untracked entries encompassed by the untracked entries which are not
pruned away.
A memory leak is also fixed in cmd_clean().
This also fixes the known breakage in t7300, since clean -d now skips
untracked directories containing ignored paths.

If the user asks to display (or sort by) the %(HEAD) atom,

We do so by resolving HEAD fresh when calling populate_value()

have a measurable impact on runtime.
Instead, let's resolve HEAD once when we realize we need the

"git interpret-trailers" is unaware of the cut line, and assumes the
trailer block would be at the end of the whole thing. This can easily
be seen with:
$ GIT_EDITOR='git interpret-trailers --in-place --trailer Acked-by:me' \
git commit --amend -v
Teach "git interpret-trailers" to notice the cut-line and ignore the
remainder of the input when looking for a place to add new trailer
block. This makes it consistent with how "git commit -v -s" inserts a
new Signed-off-by: line.
This can be done by the same logic as the existing helper function,
wt_status_truncate_message_at_cut_line(), uses, but it wants the caller
to pass a strbuf to it. Because the function ignore_non_trailer() used
by the command takes a <pointer, length> pair, not a strbuf, steal the
logic from wt_status_truncate_message_at_cut_line() to create a new
wt_status_locate_end() helper function that takes <pointer, length>
pair, and make ignore_non_trailer() call it to help "interpret-trailers".
Since there is only one caller of wt_status_truncate_message_at_cut_line()
in cmd_commit(), rewrite it to call wt_status_locate_end() helper instead
and remove the old helper that no longer has any caller.

One test in t5400 examines the packet exchange between git-push and
git-receive-pack. The latter inherits the GIT_TRACE_PACKET environment
variable, so that both processes dump trace data into the same file
concurrently. This should not be a problem because the trace file is
opened with O_APPEND.
On Windows, however, O_APPEND is not atomic as it should be: it is
emulated as lseek(SEEK_END) followed by write(). For this reason, the
test is unreliable: it can happen that one process overwrites a line
that was just written by the other process. As a consequence, the test
sometimes does not find one or another line that is expected (and it is
also successful occasionally).
The test case is actually only interested in the output of git-push.
To ensure that only git-push writes to the trace file, override the
receive-pack command such that it does not even open the trace file.

The "--local" option instructs git-config to read or modify
the repository-level config. This doesn't make any sense if
you're not actually in a repository.
Older versions of Git would blindly try to read or write
".git/config". For reading, this would result in a quiet
failure, since there was no config to read (and thus no
matching config value). Writing would generally fail
noisily, since ".git" was unlikely to exist. But since
b1ef400ee (setup_git_env: avoid blind fall-back to ".git",
2016-10-20), we catch this in the call to git_pathdup() and
die with an assertion.
Dying is the right thing to do, but we should catch the
problem early and give a more human-friendly error message.
Note that even without --local, git-config will sometimes
default to using local repository config (e.g., when
writing). These cases are already protected by similar
checks, and covered by a test in t1308.

There's a convention in Git's code base to write assertions
as:
if (...some_bad_thing...)
die("BUG: the terrible thing happened");
with the idea that users should never see a "BUG:" message
(but if they, it at least gives a clue what happened). We
use die() here because it's convenient, but there are a few
draw-backs:
1. Without parsing the messages, it's hard for callers to
distinguish BUG assertions from regular errors.
For instance, it would be nice if the test suite could
check that we don't hit any assertions, but
test_must_fail will pass BUG deaths as OK.
2. It would be useful to add more debugging features to
BUG assertions, like file/line numbers or dumping core.
3. The die() handler can be replaced, and might not
actually exit the whole program (e.g., it may just
pthread_exit()). This is convenient for normal errors,
but for an assertion failure (which is supposed to
never happen), we're probably better off taking down
the whole process as quickly and cleanly as possible.
We could address these by checking in die() whether the
error message starts with "BUG", and behaving appropriately.
But there's little advantage at that point to sharing the
die() code, and only downsides (e.g., we can't change the
BUG() interface independently). Moreover, converting all of
the existing BUG calls reveals that the test suite does
indeed trigger a few of them.
Instead, this patch introduces a new BUG() function, which
prints an error before dying via SIGABRT. This gives us test
suite checking and core dumps. The function is actually a
macro (when supported) so that we can show the file/line
number.
We can convert die("BUG") invocations to BUG() in further
patches, dealing with any test fallouts individually.

fatal: just how do you expect me to merge 0 trees?
When lucky, that could produce an ah-hah moment for the user, but it's
more likely to irritate and distract them.
Instead, tell the user plainly that the tree argument is
required. Also document this requirement in the git-read-tree(1)
manpage where there is room to explain it in a more straightforward way.

There has been a bug report by a corporate user that stated that
"spelling mistake of stash followed by a yes prints character 'y'
infinite times."
This analysis was false. When the spelling of a command contains
errors, the git program tries to help the user by providing candidates
which are close to the unexisting command. E.g Git prints the
following:
git: 'stahs' is not a git command. See 'git --help'.
Did you mean this?
stash
and then exits.
The problem with this hint is that it is not formally indicated as an
hint and the user is in fact encouraged to reply to the question,
whereas the Git command is already finished.
The user was unlucky enough that it was the command he was looking
for, and replied "yes" on the command line, effectively launching the
`yes` program.
The initial error is that the Git programs, when launched in
command-line mode (without interaction) must not ask questions,
because these questions would normally require a user input as a reply
that they won't handle indeed. That's a source of confusion on UX
level.
To improve the general usability of the Git suite, the following rule
was applied:
if the sentence
* appears in a non-interactive session
* is printed last before exit
* is a question addressing the user ("you")
the sentence is turned into affirmative and proposes the option.
The basic rewording of the question sentences has been extended to
other spots found in the source.

Most of the include examples use "foo.inc", but some use
"foo". Since the string of examples are meant to show
variations and how they differ, it's a good idea to change
only one thing at a time. The filename differences are not
relevant to what we're trying to show.

Using the word "expand" to refer to including the contents
of another config file isn't really accurate, since it's a
verbatim insertion. And it can cause confusion with the
expanding of the path itself via things like "~".
Let's clarify when we are referring to the contents versus
the filename, and use appropriate verbs in each case.

The changes in the previous commit hopefully clarify that
the evaluation of an include "path" variable is the same no
matter if it's in a conditional section or not. But since
this question came up on the list, let's add an example that
makes it obvious.

The "includeIf" directives behave exactly like include ones,
except they only kick in when the conditional is true. That
was mentioned in the "conditional" section, but let's make
it more clear for the whole "includes" section, since people
don't necessarily read the documentation top to bottom.

Add a job to run Git tests with GETTEXT_POISON. In this job we don't run
the git-p4, git-svn, and HTTPD tests to save resources/time (those tests
are already executed in other jobs). Since we don't run these tests, we
can also skip the "before_install" step (which would install the
necessary dependencies) with an empty override.

The command that made the "prove cache" persistent across builds was
executed in the "before_install" step. Consequently, every job that
wanted to make use of the cache had to run this step.
The "prove cache" is only used in the "script" step for the
"make test" command. Therefore, we should configure the "prove cache"
in this step.
This change is useful for a subsequent patch that adds a job which does
not need the "before_install" step but wants to run the "script" step to
execute the tests.

The GETTEXT_POISON=YesPlease compile-time testing option added in my
bb946bba76 ("i18n: add GETTEXT_POISON to simulate unfriendly
translator", 2011-02-22) has been slowly bitrotting as strings have
been marked for translation, and new tests have been added without
running it.
I brought this up on the list ("[BUG] test suite broken with
GETTEXT_POISON=YesPlease", [1]) asking whether this mode was useful at
all anymore. At least one person occasionally uses it, and Lars
Schneider offered to change one of the the Travis builds to run in
this mode, so fix up the failing ones.
My test setup runs most of the tests, with the notable exception of
skipping all the p4 tests, so it's possible that there's still some
lurking regressions I haven't fixed.
