c420df7b9b t5000: integrate export-subst tests into regular tests
Instead of creating extra archives for testing substitutions, set the
attribute export-subst and overwrite the marked file with the expected
(expanded) content right between committing and archiving.  Thus
placeholder expansion based on the committed content is performed with
each archive creation and the comparison with the contents of directory
a yields the correct result.  We can then remove the special tests for
export-subst.

Commit 02c5631 (difftool --dir-diff: symlink all files matching the
working tree, 2013-03-14) does not handle the case where a file that is
being compared does not exist in the working tree.  Fix this by checking

84cf246670 strbuf_branchname(): do not double-expand @{-1}~22
If you were on 'frotz' branch before you checked out your current
branch, "git merge @{-1}~22" means the same as "git merge frotz~22".

The strbuf_branchname() function, when interpret_branch_name() gives
up resolving "@{-1}~22" fully, returns "frotz" and tells the caller
that it only resolved "@{-1}" part of the input, mistakes this as a
total failure, and appends the whole thing to the result, yielding
"frotz@{-1}~22", which does not make any sense.

Inspect the return value from interpret_branch_name() a bit more
carefully.  When it errored out without consuming anything, we will
get -1 and we should return the whole thing.  Otherwise, we should
append the remainder (i.e. "~22" in the earlier example) to the
partially resolved name (i.e. "frotz").

The test suite adds enough number of checkout to make @{-12} in the
last test in t0100 that tried to check "we haven't flipped branches
that many times" error case succeed; raise the number to a hundred.

a765499a08 revision.c: treat A...B merge bases as if manually specified
The documentation assures users that "A...B" is defined as "A B --not
$(git merge-base --all A B)". This wasn't in fact quite true, because
the calculated merge bases were not sent to add_rev_cmdline().

The main effect of this was that although

  git rev-list --ancestry-path A B --not $(git merge-base --all A B)

worked, the simpler form

  git rev-list --ancestry-path A...B

failed with a "no bottom commits" error.

Other potential users of bottom commits could also be affected by this
problem, if they examine revs->cmdline_info; I came across the issue in
my proposed history traversal refinements series.

So ensure that the calculated merge bases are sent to add_rev_cmdline(),
flagged with new 'whence' enum value REV_CMD_MERGE_BASE.

aac385717a combine-diff.c: Fix output when changes are exactly 3 lines apart
When a deletion is followed by exactly 3 (or whatever the number of
context lines) unchanged lines, followed by another change, the combined
diff output would hide the first deletion, resulting in a malformed
diff.

This happened because the 3 lines before each change are painted
interesting, but also marked as no_pre_delete to prevent showing deletes
that were previously marked as uninteresting. This behaviour was
introduced in c86fbe53 (diff -c/--cc: do not include uninteresting
deletion before leading context). However, as a side effect, this could
also mark deletes that were already interesting as no_pre_delete. This
would happen only if the delete was exactly 3 lines away from the next
change, since lines farther away would not be touched by the "paint
three lines before the change" code and lines closer would be painted
by the "merge two adjacent hunks" code instead, which does not set the
no_pre_delete flag.

This commit fixes this problem by only setting the no_pre_delete flag
for changes that were previously uninteresting.

5e2c7cd2c1 t5551: do not use unportable sed '\+'
The set-up step to prepare a repository with 50000 tags used a
non-porable '\+' to match one-or-more.

The error was not caught because the next test that uses that
repository did not even bother to check if these expected tags were
actually cloned to the resulting repository.

Fix the sed construct to use BRE and update the "clone" test that
wanted to test cloning from such a repository with many refs to
check the resulting repository.

f269048754 fetch: opportunistically update tracking refs
When we run a regular "git fetch" without arguments, we
update the tracking refs according to the configured
refspec. However, when we run "git fetch origin master" (or
"git pull origin master"), we do not look at the configured
refspecs at all, and just update FETCH_HEAD.

We miss an opportunity to update "refs/remotes/origin/master"
(or whatever the user has configured). Some users find this
confusing, because they would want to do further comparisons
against the old state of the remote master, like:

  $ git pull origin master
  $ git log HEAD...origin/master

In the currnet code, they are comparing against whatever
commit happened to be in origin/master from the last time
they did a complete "git fetch".  This patch will update a
ref from the RHS of a configured refspec whenever we happen
to be fetching its LHS. That makes the case above work.

The downside is that any users who really care about whether
and when their tracking branches are updated may be
surprised.

51f8c814d5 t5510: start tracking-ref tests from a known state
We have three sequential tests for for whether tracking refs
are updated by various fetches and pulls; the first two
should not update the ref, and the third should. Each test
depends on the state left by the test before.

This is fragile (a failing early test will confuse later
tests), and means we cannot add more "should update" tests
after the third one.

Let's instead save the initial state before these tests, and
then reset to a known state before running each test.

ea2d20d4c2 t5004: avoid using tar for checking emptiness of archive
Test 2 of t5004 checks if a supposedly empty tar archive really
contains no files.  24676f02 (t5004: fix issue with empty archive test
and bsdtar) removed our commit hash to make it work with bsdtar, but
the test still fails on NetBSD and OpenBSD, which use their own tar
that considers a tar file containing only NULs as broken.

Here's what the different archivers do when asked to create a tar
file without entries:

	$ uname -v
	NetBSD 6.0.1 (GENERIC)
	$ gtar --version | head -1
	tar (GNU tar) 1.26
	$ bsdtar --version
	bsdtar 2.8.4 - libarchive 2.8.4

	$ : >zero.tar
	$ perl -e 'print "\0" x 10240' >tenk.tar
	$ sha1 zero.tar tenk.tar
	SHA1 (zero.tar) = da39a3ee5e6b4b0d3255bfef95601890afd80709
	SHA1 (tenk.tar) = 34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c

	$ : | tar cf - -T - | sha1
	da39a3ee5e6b4b0d3255bfef95601890afd80709
	$ : | gtar cf - -T - | sha1
	34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c
	$ : | bsdtar cf - -T - | sha1
	34e163be8e43c5631d8b92e9c43ab0bf0fa62b9c

So NetBSD's native tar creates an empty file, while GNU tar and bsdtar
both give us 10KB of NULs -- just like git archive with an empty tree.
Now let's see how the archivers handle these two kinds of empty tar
files:

	$ tar tf zero.tar; echo $?
	tar: Unexpected EOF on archive file
	1
	$ gtar tf zero.tar; echo $?
	gtar: This does not look like a tar archive
	gtar: Exiting with failure status due to previous errors
	2
	$ bsdtar tf zero.tar; echo $?
	0

	$ tar tf tenk.tar; echo $?
	tar: Cannot identify format. Searching...
	tar: End of archive volume 1 reached
	tar: Sorry, unable to determine archive format.
	1
	$ gtar tf tenk.tar; echo $?
	0
	$ bsdtar tf tenk.tar; echo $?
	0

NetBSD's tar complains about both, bsdtar happily accepts any of them
and GNU tar doesn't like zero-length archive files.  So the safest
course of action is to stay with our block-of-NULs format which is
compatible with GNU tar and bsdtar, as we can't make NetBSD's native
tar happy anyway.

We can simplify our test, however, by taking tar out of the picture.
Instead of extracting the archive and checking for the non-presence of
files, check if the file has a size of 10KB and contains only NULs.
This makes t5004 pass on NetBSD and OpenBSD.

56ee96572a t5004: resurrect original empty tar archive test
Add a test to verify the emptiness of an archive by extracting its
contents.  Don't run this test if the version of tar doesn't support
archives containing only a comment header, though.

The existing check 'tar archive of empty tree is empty' used to work
like that (minus the tar capability check) but was changed to depend
on the exact representation of empty tar files created by git archive
instead of on the behaviour of tar in order to avoid issues with
different tar versions.

The different approaches test different things: The existing one is
for empty trees, for which we know the exact expected output and thus
we can simply check it without extracting; the new one is for commits
with empty trees, whose archives include stamps and so the more
"natural" check by extraction is a better fit because it focuses on
the interesting aspect, namely the absence of any archive entries.

git-merge-tree causes a null pointer dereference when a directory

When this happens, we want to handle the entry as a directory and not
attempt to mark it as a file merge.  Do this by setting the entries bit
in the directory mask when the entry is missing or when it is a
directory, only performing the file comparison when we know that a file
entry exists.

694b7a1999 repack_without_ref(): write peeled refs in the rewritten file
When a reference that existed in the packed-refs file is deleted, the
packed-refs file must be rewritten.  Previously, the file was
rewritten without any peeled refs, even if the file contained peeled
refs when it was read.  This was not a bug, because the packed-refs
file header didn't claim that the file contained peeled values.  But
it had a performance cost, because the repository would lose the
benefit of having precomputed peeled references until pack-refs was
run again.

Teach repack_without_ref() to write peeled refs to the packed-refs
file (regardless of whether they were present in the old version of
the file).

This means that if the old version of the packed-refs file was not
fully peeled, then repack_without_ref() will have to peel references.
To avoid the expense of reading lots of loose references, we take two
shortcuts relative to pack-refs:

* If the peeled value of a reference is already known (i.e., because
  it was read from the old version of the packed-refs file), then
  output that peeled value again without any checks.  This is the
  usual code path and should avoid any noticeable overhead.  (This is
  different than pack-refs, which always re-peels references.)

* We don't verify that the packed ref is still current.  It could be
  that a packed references is overridden by a loose reference, in
  which case the packed ref is no longer needed and might even refer
  to an object that has been garbage collected.  But we don't check;
  instead, we just try to peel all references.  If peeling is
  successful, the peeled value is written out (even though it might
  not be needed any more); if not, then the reference is silently
  omitted from the output.

The extra overhead of peeling references in repack_without_ref()
should only be incurred the first time the packed-refs file is written
by a version of Git that knows about the "fully-peeled" attribute.

c995de61cd t3211: demonstrate loss of peeled refs if a packed ref is deleted
Add a test that demonstrates that the peeled values recorded in
packed-refs are lost if a packed ref is deleted.  (The code in
repack_without_ref() doesn't even attempt to write peeled refs.)  This
will be fixed in a moment.

ab292bc4f3 repack_without_ref(): silence errors for dangling packed refs
Stop emitting an error message when deleting a packed reference if we
find another dangling packed reference that is overridden by a loose
reference.  See the previous commit for a longer explanation of the
issue.

We have to be careful to make sure that the invalid packed reference
really *is* overridden by a loose reference; otherwise what we have
found is repository corruption, which we *should* report.

Please note that this approach is vulnerable to a race condition
similar to the race conditions already known to affect packed
references [1]:

* Process 1 tries to peel packed reference X as part of deleting
  another packed reference.  It discovers that X does not refer to a
  valid object (because the object that it referred to has been
  garbage collected).

* Process 2 tries to delete reference X.  It starts by deleting the
  loose reference X.

* Process 1 checks whether there is a loose reference X.  There is not
  (it has just been deleted by process 2), so process 1 reports a
  spurious error "X does not point to a valid object!"

The worst case seems relatively harmless, and the fix is identical to
the fix that will be needed for the other race conditions (namely
holding a lock on the packed-refs file during *all* reference
deletions), so we leave the cleaning up of all of them as a future
project.

0a0b8d1531 t3210: test for spurious error messages for dangling packed refs
A packed reference can be overridden by a loose reference, in which
case the packed reference is obsolete and is never used.  The object
pointed to by such a reference can be garbage collected.  Since
d66da478f2, this could lead to the emission of a spurious error
message:

    error: refs/heads/master does not point to a valid object!

The error is generated by repack_without_ref() if there is an obsolete
dangling packed reference in packed-refs when the packed-refs file has
to be rewritten due to the deletion of another packed reference.  Add
a failing test demonstrating this problem and some passing tests of
related scenarios.

b96114edb3 t0008: use named pipe (FIFO) to test check-ignore streaming
sleeps in the check-ignore test suite are not ideal since they can
fail when the system is under load, or when a tool like valgrind is
used which drastically alters the timing.  Therefore we replace them
with a more robust solution using a named pipe (FIFO).

Thanks to Jeff King for coming up with the redirection wizardry
required to make this work.

2d14e13c56 test output: respect $TEST_OUTPUT_DIRECTORY
Most test results go in $TEST_OUTPUT_DIRECTORY, but the output files for
tests run with --tee or --valgrind just use bare "test-results".
Changes these so that they do respect $TEST_OUTPUT_DIRECTORY.

As a result of this, the valgrind/analyze.sh script may no longer
inspect the correct files so it is also updated to respect
$TEST_OUTPUT_DIRECTORY by adding it to GIT-BUILD-OPTIONS.  This may be a
regression for people who have TEST_OUTPUT_DIRECTORY in their config.mak
but want to override it in the environment, but this change merely
brings it into line with GIT_TEST_OPTS which already cannot be
overridden if it is specified in config.mak.

6a776acabf t/Makefile: remove smoke test targets
Commit d24fbca (Remove Git's support for smoke testing - 2011-12-23)
removed the smoke test support from the test suite but it was
re-added by commit 342e9ef (Introduce a performance testing
framework - 2012-02-17).  This appears to be the result of a
mis-rebase, since re-adding the smoke testing infrastructure does
not relate to the subject of that commit.

The current 'smoke' target is broken since the 'harness' script it
uses no longer exists, so just reapply this section of commit d24fbca
and remove all of the smoke testing section in the makefile.

It is not a portable expectation that a single-shot environment
variable assignment works when calling a shell function, not a
command.

Set and export the variable before calling "test_must_fail git push"
instead.  This change would not hurt because this is the last
command in the subprocess and the environment will not seep through
to later tests without using a single-shot assignment.

b71dc3e1a0 bash-prompt.sh: show where rebase is at when stopped
When a rebase stops (e.g. interrupted by a merge conflict), it could
be useful to know how far a rebase has progressed and how many
commits in total this rebase will apply. Teach the __git_ps1()
command to display the number of commits so far applied and the
total number of commits to be applied, like this:

  ((3ec0a6a...)|REBASE 2/5)

In the example above the rebase has stopped at the second commit due to
a merge conflict and there are a total number of five commits to be
applied by this rebase.

This information can be already obtained from the following files which are
being generated during the rebase:

    GIT_DIR/.git/rebase-merge/msgnum (git-rebase--merge.sh)
    GIT_DIR/.git/rebase-merge/end    (git-rebase--merge.sh)
    GIT_DIR/.git/rebase-apply/next   (git-am.sh)
    GIT_DIR/.git/rebase-apply/last   (git-am.sh)

but "rebase -i" does not leave necessary clues.

Implement this feature by doing these three things:

  1) Modify git-rebase--interactive.sh to also create

	GIT_DIR/.git/rebase-merge/msgnum
	GIT_DIR/.git/rebase-merge/end

     files for the number of commits so far applied and the total
     number of commits to be applied.

  2) Modify git-prompt.sh to read and display info from the above
     files.

  3) Update test t9903-bash-prompt.sh to reflect changes introduced
     by this patch.

This adds one test or comment for each subcommand of git-remote
according to its current documentation.  All but 'set-branches' and
'update' are listed as taking only a fixed number of arguments; for
those we can write a test with one more (bogus) argument, and see if
the command notices that.

They fail on several counts: 'add' does not check for extra arguments,
and 'show' and 'prune' actually iterate over remotes (i.e., take any
number of args).  We'll fix them in the next two patches.

The -f machinery is only there to make the tests readable while still
ensuring they pass as a whole, and will be removed in the final patch.

ea70980030 rebase: find orig_head unambiguously
When we 'git rebase $upstream', git uses 'rev-parse --verify
$current_branch' to find ORIG_HEAD.  But if $current_branch
is ambiguous, 'rev-parse --verify' emits a warning and returns
a SHA1 anyway.  When the wrong ambiguous choice is used,
git-rebase fails non-gracefully:  it emits a warning about
failing to lock $current_branch, an error about being unable to
checkout $current_branch again, and it might even decide the
rebase is a fast-forward when it is not.

In the 'rebase $upstream' case, we already know the unambiguous
spelling of $current_branch is "HEAD".  Fix git-rebase to find
$orig_head unambiguously.

Add a test in t3400-rebase.sh which creates an ambiguous branch
name and rebases it implicitly with 'git rebase $other'.

41c21f22d0 branch.c: Validate tracking branches with refspecs instead of refs/remotes/*
The current code for validating tracking branches (e.g. the argument to
the -t/--track option) hardcodes refs/heads/* and refs/remotes/* as the
potential locations for tracking branches. This works with the refspecs
created by "git clone" or "git remote add", but is suboptimal in other
cases:

 - If "refs/remotes/foo/bar" exists without any association to a remote
   (i.e. there is no remote named "foo", or no remote with a refspec
   that matches "refs/remotes/foo/bar"), then it is impossible to set up
   a valid upstream config that tracks it. Currently, the code defaults
   to using "refs/remotes/foo/bar" from repo "." as the upstream, which
   works, but is probably not what the user had in mind when running
   "git branch baz --track foo/bar".

 - If the user has tweaked the fetch refspec for a remote to put its
   remote-tracking branches outside of refs/remotes/*, e.g. by running
       git config remote.foo.fetch "+refs/heads/*:refs/foo_stuff/*"
   then the current code will refuse to use its remote-tracking branches
   as --track arguments, since they do not match refs/remotes/*.

This patch removes the "refs/remotes/*" requirement for upstream branches,
and replaces it with explicit checking of the refspecs for each remote to
determine whether a given --track argument is a valid remote-tracking
branch. This solves both of the above problems, since the matching refspec
guarantees that there is a both a remote name and a remote branch name
that can be used for the upstream config.

However, this means that refs located within refs/remotes/* without a
corresponding remote/refspec will no longer be usable as upstreams.
The few existing tests which depended on this behavioral quirk has
already been fixed in the preceding patches.

This patch fixes the last remaining test failure in t2024-checkout-dwim.

983b17d4bb t9114.2: Don't use --track option against "svn-remote"-tracking branches
We are formalizing a requirement that any remote-tracking branch to be used
as an upstream (i.e. as an argument to --track), _must_ "belong" to a
configured remote by being matched by the "dst" side of a fetch refspec.

This test uses --track against a "remotes/trunk" ref which does not belong
to any configured (git) remotes, but is instead created by "git svn fetch"
operating on an svn-remote. It does not make sense to use an svn-remote as
an upstream for a local branch, as a regular "git pull" from (or "git push"
to) it would obviously fail (instead you would need to use "git svn" to
communicate with this remote). Furthermore, the usage of --track in this
case is unnecessary, since the upstreaming config that would be created is
never used.

Simply removing --track fixes the issue without changing the expected
behavior of the test.

fa83a33b22 checkout: Use remote refspecs when DWIMming tracking branches
The DWIM mode of checkout allows you to run "git checkout foo" when there
is no existing local ref or path called "foo", and there is exactly _one_
remote with a remote-tracking branch called "foo". Git will automatically
create a new local branch called "foo" using the remote-tracking "foo" as
its starting point and configured upstream.

For example, consider the following unconventional (but perfectly valid)
remote setup:

	[remote "origin"]
		fetch = refs/heads/*:refs/remotes/origin/*
	[remote "frotz"]
		fetch = refs/heads/*:refs/remotes/frotz/nitfol/*

Case 1: Assume both "origin" and "frotz" have remote-tracking branches called
"foo", at "refs/remotes/origin/foo" and "refs/remotes/frotz/nitfol/foo"
respectively. In this case "git checkout foo" should fail, because there is
more than one remote with a "foo" branch.

Case 2: Assume only "frotz" have a remote-tracking branch called "foo". In
this case "git checkout foo" should succeed, and create a local branch "foo"
from "refs/remotes/frotz/nitfol/foo", using remote branch "foo" from "frotz"
as its upstream.

The current code hardcodes the assumption that all remote-tracking branches
must match the "refs/remotes/$remote/*" pattern (which is true for remotes
with "conventional" refspecs, but not true for the "frotz" remote above).
When running "git checkout foo", the current code looks for exactly one ref
matching "refs/remotes/*/foo", hence in the above example, it fails to find
"refs/remotes/frotz/nitfol/foo", which causes it to fail both case #1 and #2.

The better way to handle the above example is to actually study the fetch
refspecs to deduce the candidate remote-tracking branches for "foo"; i.e.
assume "foo" is a remote branch being fetched, and then map "refs/heads/foo"
through the refspecs in order to get the corresponding remote-tracking
branches "refs/remotes/origin/foo" and "refs/remotes/frotz/nitfol/foo".
Finally we check which of these happens to exist in the local repo, and
if there is exactly one, we have an unambiguous match for "git checkout foo",
and may proceed.

This fixes most of the failing tests introduced in the previous patch.

use up all 100 columns and %an needs more than 20 columns. By
replacing %>(20) with %>>(20), %an can steal spaces from %s.

%>> understands escape sequences, so %Cred does not stop it from
stealing spaces in %<(100).

a57523428b pretty: support padding placeholders, %< %> and %><
Either %<, %> or %>< standing before a placeholder specifies how many
columns (at least as the placeholder can exceed it) it takes. Each
differs on how spaces are padded:

  %< pads on the right (aka left alignment)
  %> pads on the left (aka right alignment)
  %>< pads both ways equally (aka centered)

The (<N>) follows them, e.g. `%<(100)', to specify the number of
columns the next placeholder takes.

However, if '|' stands before (<N>), e.g. `%>|(100)', then the number
of columns is calculated so that it reaches the Nth column on screen.

7e77df39bf pretty: two phase conversion for non utf-8 commits
Always assume format_commit_item() takes an utf-8 string for string
handling simplicity (we can handle utf-8 strings, but can't with other
encodings).

If commit message is in non-utf8, or output encoding is not, then the
commit is first converted to utf-8, processed, then output converted
to output encoding. This of course only works with encodings that are
compatible with Unicode.

This also fixes the iso8859-1 test in t6006. It's supposed to create
an iso8859-1 commit, but the commit content in t6006 is in UTF-8.
t6006 is now converted back in UTF-8 (the downside is we can't put
utf-8 strings there anymore).
