c21fc9d0ab t: use test_expect_code instead of hand-rolled comparison
This makes our output in the event of a failure slightly
nicer, and it means that we do not break the &&-chain.

35da1bf5d6 t: use test_might_fail for diff and grep
Some tests run diff or grep to produce an output, and then
compare the output to an expected value. We know the exit
code we expect these processes to have (e.g., grep yields 0
if it produced output and 1 otherwise), so it would not make
the test wrong to look for it. But the difference between
their output and the expected output (e.g., shown by
test_cmp) is much more useful to somebody debugging the test
than the test just bailing out.

These tests break the &&-chain to skip the exit-code check
of the process. However, we can get the same effect by using
test_might_fail. Note that in some cases the test did use
"|| return 1", which meant the test was not wrong, but it
did fool --chain-lint.

a6a4a88af0 t: fix &&-chaining issues around setup which might fail
Many tests have an initial setup step that might fail based
on whether earlier tests in the script have succeeded or
not. Using a trick like "|| true" breaks the &&-chain,
missing earlier failures (and fooling --chain-lint).

We can use test_might_fail in some cases, which is correct
and makes the intent more obvious. We can also use
test_unconfig for unsetting config (and which is more
robust, as well).

The case in t9500 is an oddball. It wants to run cmd1 _or_
cmd2, and does it like:

  cmd1 || cmd2 &&
  other_stuff

It's not wrong in this case, but it's a bad habit to get
into, because it breaks the &&-chain if used anywhere except
at the beginning of the test (and we use the correct
solution here, putting it inside a block for precedence).

0a5e3c50de t: use test_must_fail instead of hand-rolled blocks
These test scripts likely predate test_must_fail, and can be
made simpler by using it (in addition to making them pass
--chain-lint).

The case in t6036 loses some verbosity in the failure case,
but it is so tied to a specific failure mode that it is not
worth keeping around (and the outcome of the test is not
affected at all).

a167ece0c8 t: use verbose instead of hand-rolled errors
Many tests that predate the "verbose" helper function use a
pattern like:

  test ... || {
	  echo ...
	  false
  }

to give more verbose output. Using the helper, we can do
this with a single line, and avoid a || which interacts
badly with &&-chaining (besides fooling --chain-lint, we hit
the error block no matter which command in the chain failed,
so we may often show useless results).

In most cases, the messages printed by "verbose" are equally
good (in some cases better; t6006 accidentally redirects the
message to a file!). The exception is t7001, whose output
suffers slightly. However, it's still enough to show the
user which part failed, given that we will have just printed
the test script to stderr.

5ca812a19c t: assume test_cmp produces verbose output
Some tests call test_cmp, and if it fails show the actual
output generated. This is mostly pointless, as test_cmp will
already show a diff between the expected and actual output.
It also fools --chain-lint by putting an "||" in the middle
of the chain, so we'd rather not use this construct.

Note that these cases actually show a pre-processed version
of the data, rather than exactly what test_cmp would show.
However, test_cmp's output is generally good for pointing
the user in the right direction, and they can then dig in
the trash directory themselves if they want to see more
details.

60687de5ba t: fix moderate &&-chain breakage
These are tests which are missing a link in their &&-chain,
but in a way that probably does not effect the outcome of
the test. Most of these are of the form:

  some_cmd >actual
  test_cmp expect actual

The main point of the test is to verify the output, and a

"some_cmd" does not die unexpectedly after producing its

bb79af9d09 t/test-lib: introduce --chain-lint option
It's easy to miss an "&&"-chain in a test script, like:

  test_expect_success 'check something important' '
	cmd1 &&
	cmd2
	cmd3
  '

The test harness will notice if cmd3 fails, but a failure of
cmd1 or cmd2 will go unnoticed, as their exit status is lost
after cmd3 runs.

The toy example above is easy to spot because the "cmds" are
all the same length, but real code is much more complicated.
It's also difficult to detect these situations by statically
analyzing the shell code with regexps (like the
check-non-portable-shell script does); there's too much
context required to know whether a &&-chain is appropriate
on a given line or not.

This patch instead lets the shell check each test by
sticking a command with a specific and unusual return code
at the top of each test, like:

  (exit 117) &&
  cmd1 &&
  cmd2
  cmd3

In a well-formed test, the non-zero exit from the first
command prevents any of the rest from being run, and the
test's exit code is 117. In a bad test (like the one above),
the 117 is lost, and cmd3 is run.

When we encounter a failure of this check, we abort the test
script entirely. For one thing, we have no clue which subset
of the commands in the test snippet were actually run.
Running further tests would be pointless, because we're now
in an unknown state. And two, this is not a "test failure"
in the traditional sense. The test script is buggy, not the
code it is testing. We should be able to fix these problems
in the script once, and not have them come back later as a
regression in git's code.

After checking a test snippet for --chain-lint, we do still
run the test itself.  We could actually have a pure-lint
mode which just checks each test, but there are a few
reasons not to. One, because the tests are executing
arbitrary code, which could impact the later environment
(e.g., that could impact which set of tests we run at all).
And two, because a pure-lint mode would still be expensive
to run, because a significant amount of code runs outside of
the test_expect_* blocks.  Instead, this option is designed
to be used as part of a normal test suite run, where it adds
very little overhead.

Turning on this option detects quite a few problems in
existing tests, which will be fixed in subsequent patches.
However, there are a number of places it cannot reach:

 - it cannot find a failure to break out of loops on error,
   like:

     cmd1 &&
     for i in a b c; do
	     cmd2 $i
     done &&
     cmd3

   which will not notice failures of "cmd2 a" or "cmd b"

 - it cannot find a missing &&-chain inside a block or
   subfunction, like:

     foo () {
	     cmd1
	     cmd2
     }

     foo &&
     bar

   which will not notice a failure of cmd1.

 - it only checks tests that you run; every platform will
   have some tests skipped due to missing prequisites,
   so it's impossible to say from one run that the test
   suite is free of broken &&-chains. However, all tests get
   run by _somebody_, so eventually we will notice problems.

 - it does not operate on test_when_finished or prerequisite
   blocks. It could, but these tends to be much shorter and
   less of a problem, so I punted on them in this patch.

This patch was inspired by an earlier patch by Jonathan
Nieder:

f88851c637 rev-list: refuse --first-parent combined with --bisect
rev-list --bisect is used by git bisect, but never together with
--first-parent. Because rev-list --bisect together with --first-parent
is not handled currently, and even leads to segfaults, refuse to use
both options together.

Because this is not supported, it makes little sense to use git log
--bisect --first parent either, because refs/heads/bad is not limited to
the first parent chain.

c3c17bf107 filter_ref: make a copy of extra "sought" entries
If the server supports allow_tip_sha1_in_want, we add any
unmatched raw-sha1 entries in our "sought" list of refs to
the list of refs we will ask the other side for. We do so by
inserting the original "struct ref" directly into our list,
rather than making a copy. This has several problems.

The most minor problem is that one cannot ever free the
resulting list; it contains structs that are copies of the
remote refs (made earlier by fetch_pack) along with sought
refs that are referenced elsewhere.

But more importantly that we set the ref->next pointer to
NULL, chopping off the remainder of any existing list that
the ref was a part of. We get the set of "sought" refs in
an array rather than a linked list, but that array is often
in turn generated from a list.  The test modification in
t5516 demonstrates this. Rather than fetching just an exact
sha1, we fetch that sha1 plus another ref:

  - we build a linked list of refs to fetch when do_fetch
    calls get_ref_map; the exact sha1 is first, followed by
    the named ref ("refs/heads/extra" in this case).

  - we pass that linked list to transport_fetch_ref, which
    squashes it into an array of pointers

  - that array goes to fetch_pack, which calls filter_ref.
    There we generate the want list from a mix of what the
    remote side has advertised, and the "sought" entry for
    the exact sha1. We set the sought entry's "next" pointer
    to NULL.

  - after we return from transport_fetch_refs, we then try
    to update the refs by following the linked list. But our
    list is now truncated, and we do not update
    refs/heads/extra at all.

We can fix this by making a copy of the ref. There's nothing
that fetch_pack does to it that must be reflected in the
original "sought" list (and indeed, if that were the case we
would have a serious bug, because it is only exact-sha1
entries which are treated this way).

695985f483 revision: forbid combining --graph and --no-walk
Because "--graph" is about connected history while --no-walk is
about discrete points, it does not make sense to allow these two
options at the same time. [1]

This change makes a few calls to "show --graph" fail in t4052, but
asking to show one commit with graph is a nonsensical thing to do.
Thus, tests on "show --graph" in t4052 have been removed [2,3].
Same tests on "show" without --graph option have already been tested
in 4052.

3 testcases have been added to test this patch.

376e4b39d4 t5551: make EXPENSIVE test cheaper
We create 50,000 tags to check that we don't overflow the

EXPENSIVE prereq, which means people will actually run it.

It was not documented to do so, but this test was also the
only test of a clone-over-http that requires multiple POSTs
during the conversation. We can continue to test that by
dropping http.postbuffer to its minimum size, and checking
that we get two POSTs.

025232e8aa t: redirect stderr GIT_TRACE to descriptor 4
If you run a test script like:

  GIT_TRACE=1 ./t0061-run-command.sh

you may get test failures, because some tests capture and
check the stderr output from git commands (and with
GIT_TRACE set to 1, the trace output will be included
there).

When we see GIT_TRACE set like this, we print a warning to
the user. However, we can do even better than that by just
pointing it to descriptor 4, which all tests leave connected
to the test script's stderr. That's likely what the user
intended (and any scripts that do want to see GIT_TRACE
output will set GIT_TRACE themselves).

Not only does this avoid false negatives in the tests, but
it means the user will actually see trace output for git
calls that redirect their stderr (whereas before, it was
sometimes confusingly buried in a file).

immediately. This can be annoying if the test script did any
global setup, like starting apache or git-daemon, as it will
not have an opportunity to clean up after itself. A
subsequent run of the test won't be able to start its own
daemon, and will either fail or skip the tests.

e172755b1e upload-pack: fix transfer.hiderefs over smart-http
When upload-pack advertises the refs (either for a normal,
non-stateless request, or for the initial contact in a
stateless one), we call for_each_ref with the send_ref
function as its callback. send_ref, in turn, calls
mark_our_ref, which checks whether the ref is hidden, and
sets OUR_REF or HIDDEN_REF on the object as appropriate.  If
it is hidden, mark_our_ref also returns "1" to signal
send_ref that the ref should not be advertised.

If we are not advertising refs, (i.e., the follow-up
invocation by an http client to send its "want" lines), we
use mark_our_ref directly as a callback to for_each_ref. Its
marking does the right thing, but when it then returns "1"
to for_each_ref, the latter interprets this as an error and
stops iterating. As a result, we skip marking all of the
refs that come lexicographically after it. Any "want" lines
from the client asking for those objects will fail, as they
were not properly marked with OUR_REF.

To solve this, we introduce a wrapper callback around
mark_our_ref which always returns 0 (even if the ref is
hidden, we want to keep iterating). We also tweak the
signature of mark_our_ref to exclude unnecessary parameters
that were present only to conform to the callback interface.
This should make it less likely for somebody to accidentally
use it as a callback in the future.

When branch foo is checked out, change the "HEAD, foo" part of the
decorations to "HEAD -> foo". This serves to indicate both ref
decorations (helped by the spacing) as well as their relationshsip.
As a consequence, "HEAD" without any " -> " denotes a detached HEAD now.

"git status" carefully names a detached HEAD "at" resp. "from" a rev or

sequencer calls "commit" with default options, which implies
"--cleanup=default" unless the user specified something else in their

message, which is usually not an intended side-effect.

Make the sequencer use "--cleanup=verbatim" so that it preserves commit
messages independent of the default, unless the user has set config for "commit"
or the message is amended with -s or -x.

Place them in .gitignore to unclutter the output expected by the

4aff646d17 archive-zip: mark text files in archives
Set the text flag for ZIP archive entries that look like text files so
that unzip -a can be used to perform end-of-line conversions.  Info-ZIP
zip does the same.

Detect binary files the same way as git diff and git grep do, namely by
checking for the attribute "diff" and its negation "-diff", and if none
is found by falling back to checking for the presence of NUL bytes in
the first few bytes of the file contents.

7-Zip, Windows' built-in ZIP functionality and Info-ZIP unzip without
the switch -a are not affected by the change and still extract text
files without doing any end-of-line conversions.

NB: The actual end-of-line style used in the archive entries doesn't
matter to unzip -a, as it converts any CR, CRLF and LF to the line end
characters appropriate for the platform it is running on.

5ee875852e log --decorate: do not leak "commit" color into the next item
In "git log --decorate", you would see the commit header like this:

    commit ... (HEAD, jc/decorate-leaky-separator-color)

where "commit ... (" is painted in color.diff.commit, "HEAD" in
color.decorate.head, ", " in color.diff.commit, the branch name in
color.decorate.branch and then closing ")" in color.diff.commit.

If you wanted to paint the HEAD and local branch name in the same
color as the body text (perhaps because cyan and green are too faint
on a black-on-white terminal to be readable), you would not want to
have to say

    [color "decorate"]
        head = black
        branch = black

because that you would not be able to reuse same configuration on a
white-on-black terminal.  You would naively expect

    [color "decorate"]
        head = normal
	branch = normal

to work, but unfortunately it does not.  It paints the string "HEAD"
and the branch name in the same color as the opening parenthesis or
comma between the decoration elements.  This is because the code
forgets to reset the color after printing the "prefix" in its own
color.

It theoretically is possible that some people were expecting and
relying on that the attribute set as the "diff.commit" color, which
is used to draw these opening parenthesis and inter-item comma, is
inherited by the drawing of branch names, but it is not how the
coloring works everywhere else.

4d6be03b95 diffcore-rename: avoid processing duplicate destinations
The rename code cannot handle an input where we have
duplicate destinations (i.e., more than one diff_filepair in
the queue with the same string in its pair->two->path). We
end up allocating only one slot in the rename_dst mapping.
If we fill in the diff_filepair for that slot, when we
re-queue the results, we may queue that filepair multiple
times. When the diff is finally flushed, the filepair is
processed and free()d multiple times, leading to heap
corruption.

This situation should only happen when a tree diff sees
duplicates in one of the trees (see the added test for a
detailed example). Rather than handle it, the sanest thing
is just to turn off rename detection altogether for the
diff.

817d03e105 test_ln_s_add: refresh stat info of fake symbolic links
We have a helper function test_ln_s_add that inserts a symbolic link
into the index even if the file system does not support symbolic links.
There is a small flaw in the emulation path: the added entry does not
pick up stat information of the fake symbolic link from the file system,
as a consequence, the index is not exactly the same as for the "regular"
path (where symbolic links are available). To fix this, just call
git update-index again.

This flaw was revealed by the earlier change that tightened
compare_diff_raw(), because a test case in t4008 depends on the
correctly updated index.

The only only way to use a user name, a literall IPV6 address and a port
number was ssh://[user@2001:db8::1]:222/repo.git

(Thanks to Christian Taube <lists@hcf.yourweb.de> for reporting this long
standing issue)

New users would use ssh://user@[2001:db8::1]:222/repo.git,
so change the parser to handle it correctly.

Support the old legacy URLs as well, to be backwards compatible,
and avoid regressions for users which upgrade an existing installation
to a later Git version.

b485373052 daemon: sanitize incoming virtual hostname
We use the daemon_avoid_alias function to make sure that the
pathname the user gives us is sane. However, after applying
that check, we might then interpolate the path using a
string given by the server admin, but which may contain more
untrusted data from the client. We should be sure to
sanitize this data, as well.

We cannot use daemon_avoid_alias here, as it is more strict
than we need in requiring a leading '/'. At the same time,
we can be much more strict here. We are interpreting a
hostname, which should not contain slashes or excessive runs
of dots, as those things are not allowed in DNS names.

Note that in addition to cleansing the hostname field, we
must check the "canonical hostname" (%CH) as well as the
port (%P), which we take as a raw string.  For the canonical
hostname, this comes from an actual DNS lookup on the
accessed IP, which makes it a much less likely vector for
problems. But it does not hurt to sanitize it in the same
way. Unfortunately we cannot test this case easily, as it
would involve a custom hostname lookup.

We do not need to check %IP, as it comes straight from
inet_ntop, so must have a sane form.

a933c23e66 commit: avoid race when creating orphan commits
If HEAD doesn't point at anything during the initial check, then we
should make sure that it *still* doesn't point at anything when we are
ready to update the reference. Otherwise, another process might commit
while we are working (e.g., while we are waiting for the user to edit
the commit message) and we will silently overwrite it.

This fixes a failing test in t7516.

a908a31c34 commit: add tests of commit races
Committing involves the following steps:

1. Determine the current value of HEAD (if any).
2. Create the new commit object.
3. Update HEAD.

Please note that step 2 can take arbitrarily long, because it might
involve the user editing a commit message.

If a second process sneaks in a commit during step 2, then the first
commit process should fail. This is usually done correctly, because
step 3 verifies that HEAD still points at the same commit that it
pointed to during step 1.

However, if there is a race when creating an *orphan* commit, then the
test in step 3 is skipped.

Add tests for proper handling of such races. One of the new tests
fails. It will be fixed in a moment.

f471494303 git-send-email.perl: support no- prefix with older GetOptions
Only Perl version 5.8.0 or later is required, but that comes with
an older Getopt::Long (2.32) that does not support the 'no-'
prefix.  Support for that was added in Getopt::Long version 2.33.

Since the help only mentions the 'no-' prefix and not the 'no'
prefix, add explicit support for the 'no-' prefix to support
older GetOptions versions.

f400e51c13 test-lib.sh: set prerequisite SANITY by testing what we really need
What we wanted out of the SANITY precondition is that the filesystem
behaves sensibly with permission bits settings.

 - You should not be able to remove a file in a read-only directory,

 - You should not be able to tell if a file in a directory exists if
   the directory lacks read or execute permission bits.

We used to cheat by approximating that condition with "is the /
writable?" test and/or "are we running as root?" test.  Neither test
is sufficient or appropriate in environments like Cygwin.

bd9150b7e5 t/diff-lib: check exact object names in compare_diff_raw
The "sanitize" helper wanted to strip the similarity and
dissimilarity scores when making comparison, but it was
stripping away the object names as well.

While we do not want to require the exact object names the tests
expect to be maintained, as it would be seen as an extra burden,
this would have prevented us catching a silly bug such as showing
non 0{40} object name on the preimage side of an addition or on the
postimage side of a deletion, because all [0-9a-f]{40} strings were
considered equally OK.

In the longer term, when a test only wants to see the status of the
change without having to worry about object names, it should be
rewritten not to inspect the raw format.
