When lib-terminal.sh is sourced by a test script, we
immediately set up the TTY prerequisite. We do so inside a
test_expect_success, because that nicely isolates any
generated output.
However, this early test can interfere with a script that
later wants to skip all tests (e.g., t5541 then goes on to
set up the httpd server, and wants to skip_all if that
fails). TAP output doesn't let us skip everything after we
have already run at least one test.
We could fix this by reordering the inclusion of
lib-terminal.sh in t5541 to go after the httpd setup. That
solves this case, but we might eventually hit a case with
circular dependencies, where either lib-*.sh include might
want to skip_all after the other has run a test. So
instead, let's just remove the ordering constraint entirely
by doing the setup inside a test_lazy_prereq construct,
rather than in a regular test. We never cared about the
test outcome anyway (it was written to always succeed).
Note that in addition to setting up the prerequisite, the
current test also defines test_terminal. Since we can't
affect the environment from a lazy_prereq, we have to hoist
that out. We previously depended on it _not_ being defined
when the TTY prereq isn't set as a way to ensure that tests
properly declare their dependency on TTY. However, we still
cover the case (see the in-code comment for details).

When we show unmerged paths, we had an artificial 20 columns floor
for the width of labels (e.g. "both deleted:") shown next to the
pathnames. Depending on the locale, this may result in a label that
is too wide when all the label strings are way shorter than 20
columns, or no-op when a label string is longer than 20 columns.
Just drop the artificial floor. The screen real estate is better
utilized this way when all the strings are shorter.

git-clean uses read_directory to fill in a `struct dir` with
potential hits. However, read_directory does not actually
check against our pathspec. It uses a simplified version
that may turn up false positives. As a result, we need to
check that any hits match our pathspec. We do so reliably
for non-directories. For directories, if "-d" is not given
we check that the pathspec matched exactly (i.e., we are
even stricter, and require an explicit "git clean foo" to
clean "foo/"). But if "-d" is given, rather than relaxing
the exact match to allow a recursive match, we do not check
the pathspec at all.
This regression was introduced in 113f10f (Make git-clean a
builtin, 2007-11-11).

When a remote has multiple fetch refspecs and these overlap in the
target namespace, fetch may prune a remote-tracking branch which still
exists in the remote. The test uses a popular form of this, by putting
pull requests as stored in a popular hosting platform alongside "real"
remote-tracking branches.
The fetch command makes a decision of whether to prune based
on the first matching refspec, which in this case is insufficient, as it
covers the pull request names. This pair of refspecs does work as
expected if the more "specific" refspec is the first in the list.

When QUICK is set (i.e. with --quiet) we try to do as little work as
possible, stopping after seeing the first change. stat-dirty is
considered a "change" but it may turn out not, if no actual content is
changed. The actual content test is performed too late in the process
and the shortcut may be taken prematurely, leading to incorrect return
code.
Assume we do "git diff --quiet". If we have a stat-dirty file "a" and
a really dirty file "b". We break the loop in run_diff_files() and
stop after "a" because we have got a "change". Later in
diffcore_skip_stat_unmatch() we find out "a" is actually not
changed. But there's nothing else in the diff queue, we incorrectly
declare "no change", ignoring the fact that "b" is changed.
This also happens to "git diff --quiet HEAD" when it hits
diff_can_quit_early() in oneway_diff().
This patch does the content test earlier in order to keep going if "a"
is unchanged. The test result is cached so that when
diffcore_skip_stat_unmatch() is done in the end, we spend no cycles on
re-testing "a".

This patch activates the DO_MATCH_DIRECTORY code in m_p_i(), which
makes "git diff HEAD submodule/" and "git diff HEAD submodule" produce
the same output. Previously only the version without trailing slash
returns the difference (if any).
That's the effect of new ce_path_match(). dir_path_match() is not
executed by the new tests. And it should not introduce regressions.
Previously if path "dir/" is passed in with pathspec "dir/", they
obviously match. With new dir_path_match(), the path becomes
_directory_ "dir" vs pathspec "dir/", which is not executed by the old
code path in m_p_i(). The new code path is executed and produces the
same result.
The other case is pathspec "dir" and path "dir/" is now turned to
"dir" (with DO_MATCH_DIRECTORY). Still the same result before or after

Sometimes when working with a large repository it can be useful to try
out a merge and only check out conflicting files to disk (for example as
a speed optimization on a server). Until v1.7.7-rc1~28^2~20
(merge-recursive: When we detect we can skip an update, actually skip
it, 2011-08-11), it was possible to do so with the following idiom:
# Prepare a temporary index and empty work tree.
GIT_INDEX_FILE="$PWD/tmp-$$-index" &&
export GIT_INDEX_FILE &&
GIT_WORK_TREE="$PWD/tmp-$$-work" &&
export GIT_WORK_TREE &&
mkdir "$GIT_WORK_TREE" &&
# Convince the index that our side is on disk.
git read-tree -i -m $ours &&
git update-index --ignore-missing --refresh &&
# Merge their side into our side.
bases=$(git merge-base --all $ours $theirs) &&
git merge-recursive $bases -- $ours $theirs &&
tree=$(git write-tree)
Nowadays, that still works and the exit status is the same, but
merge-recursive produces a diagnostic if "our" side renamed a file:
error: addinfo_cache failed for path 'dst'

The remote we push can be defined either by
remote.pushdefault or by branch.*.pushremote for the current
branch. The order in which they appear in the config file
should not matter to precedence (which should be to prefer
the branch-specific config).
The current code parses the config linearly and uses a
single string to store both values, overwriting any
previous value. Thus, config like:
[branch "master"]
pushremote = foo
[remote]
pushdefault = bar
erroneously ends up pushing to "bar" from the master branch.
We can fix this by storing both values and resolving the
correct value after all config is read.

If an ident line has a ridiculous date value like (2^64)+1,
we currently just pass ULONG_MAX along to the date code,
which can produce nonsensical dates.
On systems with a signed long time_t (e.g., 64-bit glibc
systems), this actually doesn't end up too bad. The
ULONG_MAX is converted to -1, we apply the timezone field to
that, and the result ends up somewhere between Dec 31, 1969
and Jan 1, 1970.
However, there is still a few good reasons to detect the
overflow explicitly:
1. On systems where "unsigned long" is smaller than
time_t, we get a nonsensical date in the future.
2. Even where it would produce "Dec 31, 1969", it's easier
to recognize "midnight Jan 1" as a consistent sentinel
value for "we could not parse this".
3. Values which do not overflow strtoul but do overflow a
signed time_t produce nonsensical values in the past.
For example, on a 64-bit system with a signed long
time_t, a timestamp of 18446744073000000000 produces a
date in 1947.
We also recognize overflow in the timezone field, which
could produce nonsensical results. In this case we show the
parsed date, but in UTC.

When we check commit objects, we complain if commit->date is
ULONG_MAX, which is an indication that we saw integer
overflow when parsing it. However, we do not do any check at
all for author lines, which also contain a timestamp.
Let's actually check the timestamps on each ident line
with strtoul. This catches both author and committer lines,
and we can get rid of the now-redundant commit->date check.
Note that like the existing check, we compare only against
ULONG_MAX. Now that we are calling strtoul at the site of
the check, we could be slightly more careful and also check
that errno is set to ERANGE. However, this will make further
refactoring in future patches a little harder, and it
doesn't really matter in practice.
For 32-bit systems, one would have to create a commit at the
exact wrong second in 2038. But by the time we get close to
that, all systems will hopefully have moved to 64-bit (and
if they haven't, they have a real problem one second later).
For 64-bit systems, by the time we get close to ULONG_MAX,
all systems will hopefully have been consumed in the fiery
wrath of our expanding Sun.

When t4212 was originally added by 9dbe7c3d (pretty: handle
broken commit headers gracefully, 2013-04-17), it tested our
handling of commits with broken ident lines in which the
timestamps could not be parsed. It does so using a bogus line
like "Name <email>-<> 1234 -0000", because that simulates an
error that was seen in the wild.
Later, 03818a4 (split_ident: parse timestamp from end of
line, 2013-10-14) made our parser smart enough to actually
find the timestamp on such a line, and t4212 was adjusted to
match. While it's nice that we handle this real-world case,
this meant that we were not actually testing the
bogus-timestamp case anymore.
This patch adds a test with a totally incomprehensible
timestamp to make sure we are testing the code path.
Note that the behavior is slightly different between regular log
output and "--format=%ad". In the former case, we produce a
sentinel value and in the latter, we produce an empty
string. While at first this seems unnecessarily
inconsistent, it matches the original behavior given by
9dbe7c3d.

In smart http, upload-pack adds new shallow lines at the beginning of
each rpc response. Only shallow lines from the first rpc call are
useful. After that they are thrown away. It's designed this way
because upload-pack is stateless and has no idea when its shallow
lines are helpful or not.
So after refs are negotiated with multi_ack_detailed and the server
thinks it learned enough, it sends "ACK obj-id ready", terminates the
rpc call and waits for the final rpc round. The client sends "done".
The server sends another response, which also has shallow lines at
the beginning, and the last "ACK obj-id" line.
When no-done is active, the last round is cut out, the server sends
"ACK obj-id ready" and "ACK obj-id" in the same rpc
response. fetch-pack is updated to recognize this and not send
"done". However it still tries to consume shallow lines, which are
never sent.
Update the code, make sure to skip consuming shallow lines when
no-done is enabled.

The prefix_path_gently() function currently applies real_path to
everything if given an absolute path, dereferencing symlinks both

This causes most high-level functions to misbehave when acting on
symlinks given via absolute paths. For example
$ git add /dir/repo/symlink

In order to manipulate symlinks in the work tree using absolute paths,
symlinks should only be dereferenced outside the work tree.
Modify the prefix_path_gently() to first normalize the path in order to
make sure path levels are separated by '/', then pass the result to
'abspath_part_inside_repo' to find the part inside the work tree
(without dereferencing any symlinks inside the work tree).
For absolute paths, prefix_path_gently() did not, nor does now do, any

t7501.9 tries to check that "git commit" will fail when the
index is unchanged. It relies on previous tests not to have
modified the index. When it was originally written, this was
always the case. However, commit c65dc35 (t7501: test the
right kind of breakage, 2012-03-30) changed earlier tests (4
and 5) to leave a modification in the index.
We never noticed, however, because t7501.7, between the two,
clears the index state as a side effect. However, that test
depends on the PERL prerequisite, and so it does not always
run. Therefore if NO_PERL is set, we do not run the
intervening test, the index is left unclean, and t7501.9
fails.
We could fix this by moving t7501.9 up in the script.
However, this patch instead leaves it in place and adds a
"git reset" before the commit. This makes the test more
explicit about its preconditions, and will future-proof it
against any other changes in the test state.

We do ignore trailing slash on a directory, so pathspec "abc/" matches

to it. This makes "git log submodule-path" and "git log submodule-path/"

Commit 9d7d446 (git p4: submit files with wildcards, 2012-04-29)
fixed problems with handling files that had p4 wildcard
characters, like "@" and "*". But it missed one case, that of
RCS keyword scrubbing, which uses "p4 fstat" to extract type
information. Fix it by calling wildcard_encode() on the raw
filename.

Generating the submit template for p4 uses tempfile.mkstemp(),
which by default puts files in /tmp. For a test that fails,
possibly on purpose, this is not cleaned up. Run with TMPDIR
pointing into the trash directory so the temp files go away
with the test results.
To do this required some other minor changes. First, the editor
is launched using system(editor + " " + template_file), using
shell expansion to build the command string. This doesn't work
if editor has a space in it. And is generally unwise as it's
easy to fool the shell into doing extra work. Exec the args
directly, without shell expansion.
Second, without shell expansion, the trick of "P4EDITOR=:" used
in the tests doesn't work. Use a real command, true, as the
non-interactive editor for testing.

Damien Gérard highlights an interesting problem. Some p4
repositories end up with symlinks that have an empty target. It
is not possible to create this with current p4, but they do
indeed exist.
The effect in git p4 is that "p4 print" on the symlink returns an
empty string, confusing the curret symlink-handling code.
Such broken repositories cause problems in p4 as well, even with
no git involved. In p4, syncing to a change that includes a
bogus symlink causes errors:
//depot/empty-symlink - updating /home/me/p4/empty-symlink
rename: /home/me/p4/empty-symlink: No such file or directory
and leaves no symlink.
In git, replicate the p4 behavior by ignoring these bad symlinks.
If, in a later p4 revision, the symlink happens to point to
something non-null, the symlink will be replaced properly.
Add a big test for all this too.
This happens to be a regression introduced by 1292df1 (git-p4:
Fix occasional truncation of symlink contents., 2013-08-08) and
appeared first in 1.8.5. But it shows up only in p4 repositories
of dubious character, so can wait for a proper release.

We time a straight "rev-list --all" and its "--object"
counterpart, both going all the way to the root. However, we
do not time a partial history walk. This patch adds an
extreme case: a walk over a very small slice of history, but
with a very large set of UNINTERESTING tips. This is similar
to the connectivity check run by git on a small fetch, or
the walk done by any pre-receive hooks that want to check
incoming commits.
This test reveals a performance regression in git v1.8.4.2,
caused by fbd4a70 (list-objects: mark more commits as edges

With the previous fix 895c5ba3 (revision: do not peel tags used in
range notation, 2013-09-19), handle_revision_arg() that processes
command line arguments for the "git log" family of commands no
longer directly places the object pointed by the tag in the pending
object array when it sees a tag object. We used to place pointee
there after copying the flag bits like UNINTERESTING and
SYMMETRIC_LEFT.
This change meant that any flag that is relevant to later history
traversal must now be propagated to the pointed objects (most often
these are commits) while starting the traversal, which is partly
done by handle_commit() that is called from prepare_revision_walk().
We did propagate UNINTERESTING, but did not do so for others, most
notably SYMMETRIC_LEFT. This caused "git log --left-right v1.0..."
(where "v1.0" is a tag) to start losing the "leftness" from the
commit the tag points at.

"git rev-list --objects ^A^{tree} B^{tree}" ought to mean "I want a
list of objects inside B's tree, but please exclude the objects that
appear inside A's tree".
we see the top-level tree marked as uninteresting (i.e. ^A^{tree} in
the above example) and call mark_tree_uninteresting() on it; this
unfortunately prevents us from recursing into the tree and marking
the objects in the tree as uninteresting.
The reason why "git log ^A A" yields an empty set of commits,
i.e. we do not have a similar issue for commits, is because we call
mark_parents_uninteresting() after seeing an uninteresting commit.
The uninteresting-ness of the commit itself does not prevent its
parents from being marked as uninteresting.
Introduce mark_tree_contents_uninteresting() and structure the code
in handle_commit() in such a way that it makes it the responsibility
of the callchain leading to this function to mark commits, trees and
blobs as uninteresting, and also make it the responsibility of the
helpers called from this function to mark objects that are reachable
from them.
Note that this is a very old bug that probably dates back to the day
when "rev-list --objects" was introduced. The line to clear
tree->object.parsed at the end of mark_tree_contents_uninteresting()
can be removed when this fix is merged to the codebase after
6e454b9a (clear parsed flag when we free tree buffers, 2013-06-05).

When we parse a string like "foo@{upstream}", we look for
the first "@"-sign, and check to see if it is an upstream
mark. However, since branch names can contain an @, we may
also see "@foo@{upstream}". In this case, we check only the
first @, and ignore the second. As a result, we do not find
the upstream.
We can solve this by iterating through all @-marks in the
string, and seeing if any is a legitimate upstream or
empty-at mark.
Another strategy would be to parse from the right-hand side
of the string. However, that does not work for the
"empty_at" case, which allows "@@{upstream}". We need to
find the left-most one in this case (and we then recurse as
"HEAD@{upstream}").

get_sha1() cannot currently parse a valid object name like
"HEAD:@{upstream}" (assuming that such an oddly named file
exists in the HEAD commit). It takes two passes to parse the
string:
1. It first considers the whole thing as a ref, which
results in looking for the upstream of "HEAD:".
2. It finds the colon, parses "HEAD" as a tree-ish, and then
finds the path "@{upstream}" in the tree.
For a path that looks like a normal reflog (e.g.,
"HEAD:@{yesterday}"), the first pass is a no-op. We try to
dwim_ref("HEAD:"), that returns zero refs, and we proceed
with colon-parsing.
For "HEAD:@{upstream}", though, the first pass ends up in
interpret_upstream_mark, which tries to find the branch
"HEAD:". When it sees that the branch does not exist, it
actually dies rather than returning an error to the caller.
As a result, we never make it to the second pass.
One obvious way of fixing this would be to teach
interpret_upstream_mark to simply report "no, this isn't an
upstream" in such a case. However, that would make the
error-reporting for legitimate upstream cases significantly
worse. Something like "bogus@{upstream}" would simply report
"unknown revision: bogus@{upstream}", while the current code
diagnoses a wide variety of possible misconfigurations (no
such branch, branch exists but does not have upstream, etc).
However, we can take advantage of the fact that a branch
name cannot contain a colon. Therefore even if we find an
upstream mark, any prefix with a colon must mean that
the upstream mark we found is actually a pathname, and
should be disregarded completely. This patch implements that
logic.

interpret_branch_name gets passed a "name" buffer to parse,
along with a "namelen" parameter representing its length. If
"namelen" is zero, we fallback to the NUL-terminated
string-length of "name".
However, it does not necessarily follow that if we have
gotten a non-zero "namelen", it is the NUL-terminated
string-length of "name". E.g., when get_sha1() is parsing
"foo:bar", we will be asked to operate only on the first
three characters.
Yet in interpret_branch_name and its helpers, we use string
functions like strchr() to operate on "name", looking past
the length we were given. This can result in us mis-parsing
object names. We should instead be limiting our search to
"namelen" bytes.
There are three distinct types of object names this patch
addresses:
- The intrepret_empty_at helper uses strchr to find the
next @-expression after our potential empty-at. In an
expression like "@:foo@bar", it erroneously thinks that
the second "@" is relevant, even if we were asked only
to look at the first character. This case is easy to
trigger (and we test it in this patch).
- When finding the initial @-mark for @{upstream}, we use
strchr. This means we might treat "foo:@{upstream}" as
the upstream for "foo:", even though we were asked only
to look at "foo". We cannot test this one in practice,
because it is masked by another bug (which is fixed in
the next patch).
- The interpret_nth_prior_checkout helper did not receive
the name length at all. This turns out not to be a
problem in practice, though, because its parsing is so
limited: it always starts from the far-left of the
string, and will not tolerate a colon (which is
currently the only way to get a smaller-than-strlen
"namelen"). However, it's still worth fixing to make the
code more obviously correct, and to future-proof us
against callers with more exotic buffers.

Currently fetching a one-level ref like "refs/foo" does not
work consistently. The outer "git fetch" program filters the
list of refs, checking each against check_refname_format.
Then it feeds the result to do_fetch_pack to actually
negotiate the haves/wants and get the pack. The fetch-pack
code does its own filter, and it behaves differently.
The fetch-pack filter looks for refs in "refs/", and then
feeds everything _after_ the slash (i.e., just "foo") into
check_refname_format. But check_refname_format is not
designed to look at a partial refname. It complains that the
ref has only one component, thinking it is at the root
(i.e., alongside "HEAD"), when in reality we just fed it a
partial refname.
As a result, we omit a ref like "refs/foo" from the pack
request, even though "git fetch" then tries to store the
resulting ref. If we happen to get the object anyway (e.g.,
because the ref is contained in another ref we are
fetching), then the fetch succeeds. But if it is a unique
object, we fail when trying to update "refs/foo".
We can fix this by just passing the whole refname into
check_refname_format; we know the part we were omitting is
"refs/", which is acceptable in a refname. This at least
makes the checks consistent with each other.
This problem happens most commonly with "refs/stash", which
is the only one-level ref in wide use. However, our test
does not use "refs/stash", as we may later want to restrict
it specifically (not because it is one-level, but because
of the semantics of stashes).
We may also want to do away with the multiple levels of
filtering (which can cause problems when they are out of
sync), or even forbid one-level refs entirely. However,
those decisions can come later; this fixes the most
immediate problem, which is the mismatch between the two.
