e6d65c9a47 t5304: test cleaning pack garbage
Pack garbage, noticeably stale .idx files, can be cleaned up during
a garbage collection.  This tests to ensure such garbage is properly
cleaned up.

Note that the prior test for checking pack garbage with count-objects
left some stale garbage after the test exited.  This has also been
corrected.

baf0a3e47d wt-status: avoid building bogus branch name with detached HEAD
If we're on a detached HEAD then wt_shortstatus_print_tracking() takes
the string "HEAD (no branch)", translates it, skips the first eleven
characters and passes the result to branch_get(), which returns a bogus
result and accesses memory out of bounds in order to produce it.
Somehow stat_tracking_info(), which is passed that result, does the
right thing anyway, i.e. it finds that there is no base.

Avoid the bogus results and memory accesses by checking for HEAD first
and exiting early in that case.  This fixes t7060 with --valgrind.

ec352401fb blame: test to describe use of blame --reverse --first-parent
Reverse blame can be used to locate removal of lines which does not
change adjacent lines. Such edits do not appear in non-reverse blame,
because the adjacent lines last changed commit is older history, before
the edit.

For a big and active project which uses topic branches, or analogous
feature, for example pull-requests, the history can contain many
concurrent branches, and even after an edit merged into the target
branch, there are still many (sometimes several tens or even hundreds)
topic branch which do not contain it:

 a0--a1-----*a2-*a3-a4...-*a100
 |\         /   /         /
 | b0-B1..bN   /         /
 |\           /         /
 | c0..   ..cN         /
 \                    /
  z0..            ..zN

Here, the '*'s mark the first parent in merge, and uppercase B1 - the
commit where the line being blamed for was removed. Since commits cN-zN
do not contain B1, they still have the line removed in B1, and
reverse blame can report that the last commit for the line was zN
(meaning that it was removed in a100). In fact it really does return
some very late commit, and this makes it unusable for finding the B1
commit.

The search could be done by blame --reverse --first-parent. For range
a0..a100 it would return a1, and then only one additional blame along
the a0..bN will return the desired commit b0. But combining --reverse
and --first-parent was forbidden in 95a4fb0eac, because incorrectly
specified range could produce unexpected and meaningless result.

Add test which describes the expected behavior of
`blame --reverse --first-parent` in the case described above.

9e468334b4 ref-filter: fallback on alphabetical comparison
In ref-filter.c the comparison of refs while sorting is handled by
cmp_ref_sorting() function. When sorting as per numerical values
(e.g. --sort=objectsize) there is no fallback comparison when both
refs hold the same value. This can cause unexpected results (i.e. the
order of listing refs with equal values cannot be pre-determined) as
pointed out by Johannes Sixt ($gmane/280117).

Hence, fallback to alphabetical comparison based on the refname
whenever the other criterion is equal.

A test in t3203 was expecting that branch-two sorts before HEAD, which
happened to be how qsort(3) on Linux sorted the array, but (1) that
outcome was not even guaranteed, and (2) once we start breaking ties
with the refname, "HEAD" should sort before "branch-two" so the
original expectation was inconsistent with the criterion we now use.

Update it to match the new world order, which we can now depend on
being stable.

cfe2d4be91 difftool: ignore symbolic links in use_wt_file
The caller is preparing a narrowed-down copy of the working tree and
this function is asked if the path should be included in that copy.
If we say yes, the path from the working tree will be either symlinked
or copied into the narrowed-down copy.

For any path that is a symbolic link, the caller later fixes up the
narrowed-down copy by unlinking the path and replacing it with a
regular file it writes out that mimics the way how "git diff"
compares symbolic links.

Let's answer "no, you do not want to copy/symlink the working tree
file" for all symbolic links from this function, as we know the
result will not be used because it will be overwritten anyway.

Incidentally, this also stops the function from feeding a symbolic
link in the working tree to hash-object, which is a wrong thing to
do to begin with. The link may be pointing at a directory, or worse
may be dangling (both would be noticed as an error).  Even if the
link points at a regular file, hashing the contents of a file that
is pointed at by the link is not correct (Git hashes the contents of
the link itself, not the pointee).

e34f80278e merge-file: clamp exit code to maximum 127
Git-merge-file is documented to return one of three exit
codes:

  - zero means the merge was successful

  - a negative number means an error occurred

  - a positive number indicates the number of conflicts

Unfortunately, this all gets stuffed into an 8-bit return
code. Which means that if you have 256 conflicts, this wraps
to zero, and the merge appears to succeed (and commits a
blob full of conflict-marker cruft!).

This patch clamps the return value to a maximum of 127,
which we should be able to safely represent everywhere. This
also leaves 128-255 for other values. Shells (and some parts
of git) will typically represent signal death as 128 plus
the signal number. And negative values are typically coerced
to an 8-bit unsigned value (so "return -1" ends up as 255).

Technically negative returns have the same problem (e.g.,
"-256" wraps back to 0), but this is not a problem in
practice, as the only negative value we use is "-1".

39743cf554 rebase-i: work around Windows CRLF line endings
Editors on Windows can and do save text files with CRLF line
endings, which is the convention on the platform.  We are seeing
reports that the "read" command in a port of bash to the environment
however does not strip the CRLF at the end, not adjusting for the
same convention on the platform.

This breaks the recently added sanity checks for the insn sheet fed
to "rebase -i"; instead of an empty line (hence nothing in $command),
the script was getting a lone CR in there.

Special case a lone CR and treat it the same way as an empty line to
work this around.

This patch (also) passes the test with Git for Windows, where the
issue was seen first.

72fac66bca merge: detect delete/modechange conflict
If one side deletes a file and the other changes its
content, we notice and report a conflict. However, if
instead of changing the content, we change only the mode,
the merge does not notice (and the mode change is silently
dropped).

The trivial index merge notices the problem and correctly
leaves the conflict in the index, but both merge-recursive
and merge-one-file will silently resolve this in favor of
the deletion.  In many cases that is a sane resolution, but
we should be punting to the user whenever there is any
question. So let's detect and treat this as a conflict (in
both strategies).

f78d1fe208 t6031: generalize for recursive and resolve strategies
This script tests the filemode handling of merge-recursive,
but we do not test the same thing for merge-resolve. Let's
generalize the script a little:

  1. Break out the setup steps for each test into a separate
     snippet.

  2. For each test, run it twice; once with "-s recursive"
     and once with "-s resolve". We can avoid repeating
     ourselves by adding a function.

  3. Since we have a nice abstracted function, we can make
     our tests more thorough by testing both directions
     (change on "ours" versus "theirs").

This improves our test coverage, and will make this the
place to add more tests related to merging mode changes.

29abb33978 add: simplify -u/-A without pathspec
Since Git 2.0, "add -u" and "add -A" run from a subdirectory without
any pathspec mean "everything in the working tree" (before 2.0, they
were limited to the current directory).  The limiting to the current
directory was implemented by inserting "." to the command line when
the end user did not give us any pathspec.  At 2.0, we updated the
code to insert ":/" (instead of '.') to consider everything from the
top-level, by using a pathspec magic "top".

The call to parse_pathspec() using the command line arguments is,
however, made with PATHSPEC_PREFER_FULL option since 5a76aff1 (add:
convert to use parse_pathspec, 2013-07-14), which predates Git 2.0.
In retrospect, there was no need to turn "adding . to limit to the
directory" into "adding :/ to unlimit to everywhere" in Git 2.0;
instead we could just have done "if there is no pathspec on the
command line, just let it be".  The parse_pathspec() then would give
us a pathspec that matches everything and all is well.

Incidentally such a simplification also fixes a corner case bug that
stems from the fact that ":/" does not necessarily mean any magic.
A user would say "git --literal-pathspecs add -u :/" from the
command line when she has a directory ':' and wants to add
everything in it (and she knows that her :/ will be taken as
'everything under the sun' magic pathspec unless she disables the
magic with --literal-pathspecs).  The internal use of ':/' would
behave the same way as such an explicitly given ":/" when run with
"--literal-pathspecs", and will not add everything under the sun as
the code originally intended.

9b680fbd3b t7063: fix flaky untracked-cache test
Dirty the test worktree's root directory, as the test expects.

When testing the untracked-cache, we previously assumed that checking
out master would be sufficient to mark the mtime of the worktree's
root directory as racily-dirty.  But sometimes, the checkout would
happen at 12345.999 seconds and the status at 12346.001 seconds,
meaning that the worktree's root directory would not be racily-dirty.
And since it was not truly dirty, occasionally the test would fail.
By making the root truly dirty, the test will always succeed.

Tested by running a few hundred times.

710b4e8a16 t0027: improve test for not-normalized files
When a text file with mixed line endings is commited into the repo,
it is called "not normalized" (or NNO) in t0027.  The existing test
case using repoMIX did not fully test all combinations: (Especially
when core.autocrlf = true) Files with NL are not converted at
commit, but at checkout, so a warning NL->CRLF is given.  Files with
CRLF are not converted at all (so no warning will be given), unless
they are marked as "text" or "auto".

Remove repoMIX introduced in commit 8eeab92f02, and replace it with
a combination of NNO tests.

a5a4b3ff4d filter-branch: remove multi-line headers in msg filter
df062010 (filter-branch: avoid passing commit message through sed)
introduced a regression when filtering commits with multi-line headers,
if the header contains a blank line.  An example of this is a gpg-signed
commit:

  $ git cat-file commit signed-commit
  tree 3d4038e029712da9fc59a72afbfcc90418451630
  parent 110eac945dc1713b27bdf49e74e5805db66971f0
  author A U Thor <author@example.com> 1112912413 -0700
  committer C O Mitter <committer@example.com> 1112912413 -0700
  gpgsig -----BEGIN PGP SIGNATURE-----
   Version: GnuPG v1

   iEYEABECAAYFAlYXADwACgkQE7b1Hs3eQw23CACgldB/InRyDgQwyiFyMMm3zFpj
   pUsAnA+f3aMUsd9mNroloSmlOgL6jIMO
   =0Hgm
   -----END PGP SIGNATURE-----

  Adding gpg

As a consequence, "filter-branch --msg-filter cat" (which should leave the
commit message unchanged) spills the signature (after the internal blank
line) into the original commit message.

The reason is that although the signature is indented, making the line a
whitespace only line, the "read" call is splitting the line based on
the shell's IFS, which defaults to <space><tab><newline>.  The leading
space is consumed and $header_line is empty, causing the "skip header
lines" loop to exit.

The rest of the commit object is then re-used as the rewritten commit
message, causing the new message to include the signature of the
original commit.

Set IFS to an empty string for the "read" call, thus disabling the word
splitting, which causes $header_line to be set to the non-empty value ' '.
This allows the loop to fully consume the header lines before
emitting the original, intact commit message.

[jc: this is literally based on MJG's suggestion]

786b150c8d clone --dissociate: avoid locking pack files
When `git clone` is asked to dissociate the repository from the
reference repository whose objects were used, it is quite possible that
the pack files need to be repacked. In that case, the pack files need to
be deleted that were originally hard-links to the reference repository's
pack files.

On platforms where a file cannot be deleted if another process still
holds a handle on it, we therefore need to take pains to release all
pack files and indexes before dissociating.

This fixes https://github.com/git-for-windows/git/issues/446

The test case to demonstrate the breakage technically does not need to
be run on Linux or MacOSX. It won't hurt, either, though.

1db168ee97 rebase-i: loosen over-eager check_bad_cmd check
804098bb (git rebase -i: add static check for commands and SHA-1,
2015-06-29) tried to check all insns before running any in the todo
list, but it did so by implementing its own parser that is a lot
stricter than necessary.  We used to allow lines that are indented
(including comment lines), and we used to allow a whitespace between
the insn and the commit object name to be HT, among other things,
that are flagged as an invalid line by mistake.

Fix this by using the same tokenizer that is used to parse the todo
list file in the new check.

Whether it's a good thing to accept indented comments is
debatable (other commands like "git commit" do not accept them), but we
already accepted them in the past, and some people and scripts rely on
this behavior. Also, a line starting with space followed by a '#' cannot
have any meaning other than being a comment, hence it doesn't harm to
accept them as comments.

416e2b3d4b Merge branch 'jk/test-lint-forbid-when-finished-in-subshell'
Because "test_when_finished" in our test framework queues the
clean-up tasks to be done in a shell variable, it should not be
used inside a subshell.  Add a mechanism to allow 'bash' to catch
such uses, and fix the ones that were found.

* jk/test-lint-forbid-when-finished-in-subshell:
  test-lib-functions: detect test_when_finished in subshell

e6f11c19ab Merge branch 'jk/connect-clear-env'
The ssh transport, just like any other transport over the network,
did not clear GIT_* environment variables, but it is possible to
use SendEnv and AcceptEnv to leak them to the remote invocation of
Git, which is not a good idea at all.  Explicitly clear them just
like we do for the local transport.

* jk/connect-clear-env:
  git_connect: clarify conn->use_shell flag
  git_connect: clear GIT_* environment for ssh

"git log --date=local" used to only show the normal (default)

as an instruction to use the local timezone with other formats,
e.g. "git show --date=rfc-local".

a tag that points at a commit that is also being imported.

22dd6eb31f Merge branch 'ad/bisect-terms'
The use of 'good/bad' in "git bisect" made it confusing to use when
hunting for a state change that is not a regression (e.g. bugfix).
The command learned 'old/new' and then allows the end user to
say e.g. "bisect start --term-old=fast --term=new=slow" to find a
performance regression.

Michael's idea to make 'good/bad' more intelligent does have
certain attractiveness ($gname/272867), and makes some of the work
on this topic a moot point.

* ad/bisect-terms:
  bisect: allow setting any user-specified in 'git bisect start'
  bisect: add 'git bisect terms' to view the current terms
  bisect: add the terms old/new
  bisect: sanity check on terms

9958dd8685 Merge branch 'kn/for-each-tag-branch'
Some features from "git tag -l" and "git branch -l" have been made
available to "git for-each-ref" so that eventually the unified
implementation can be shared across all three, in a follow-up
series or two.

* kn/for-each-tag-branch:
  for-each-ref: add '--contains' option
  ref-filter: implement '--contains' option
  parse-options.h: add macros for '--contains' option
  parse-option: rename parse_opt_with_commit()
  for-each-ref: add '--merged' and '--no-merged' options
  ref-filter: implement '--merged' and '--no-merged' options

  for-each-ref: add '--points-at' option
  ref-filter: implement '--points-at' option

9c28390bda init: use strbufs to store paths
The init code predates strbufs, and uses PATH_MAX-sized
buffers along with many manual checks on intermediate sizes
(some of which make magic assumptions, such as that init
will not create a path inside .git longer than 50
characters).

We can simplify this greatly by using strbufs, which drops
some hard-to-verify strcpy calls in favor of git_path_buf.
While we're in the area, let's also convert existing calls
to git_path to the safer git_path_buf (our existing calls
were passed to pretty tame functions, and so were not a
problem, but it's easy to be consistent and safe here).

Note that we had an explicit test that "git init" rejects
long template directories. This comes from 32d1776 (init: Do
not segfault on big GIT_TEMPLATE_DIR environment variable,
2009-04-18). We can drop the test_must_fail here, as we now
accept this and need only confirm that we don't segfault,
which was the original point of the test.

a5db4b127b git-p4: add support for large file systems
Perforce repositories can contain large (binary) files. Migrating these
repositories to Git generates very large local clones. External storage
systems such as Git LFS [1], Git Fat [2], Git Media [3], git-annex [4]
try to address this problem.

Add a generic mechanism to detect large files based on extension,
uncompressed size, and/or compressed size.

0eb8548f45 status: don't say 'HEAD detached at HEAD'
After using "git checkout --detach", the reflog is left with an entry
like

  checkout: moving from ... to HEAD

This message is parsed to generate the 'HEAD detached at' message in
'git branch' and 'git status', which leads to the not-so-useful message
'HEAD detached at HEAD'.

Instead, when parsing such reflog entry, resolve HEAD to the
corresponding commit in the reflog, so that the message becomes 'HEAD
detached at $sha1'.
