compat/poll: prepare for targeting Windows Vista

Windows Vista (and later) actually have a working poll(), but we still
cannot use it because it only works on sockets.

So let's detect when we are targeting Windows Vista and undefine those
constants, and define `pollfd` so that we can declare our own pollfd
struct.

We also need to make sure that we override those constants *after*
`winsock2.h` has been `#include`d (otherwise we would not really
override those constants).

roll wt_status_state into wt_status and populate in... Stephen P. Smith Sun, 30 Sep 2018 14:12:45 +0000 (07:12 -0700)

roll wt_status_state into wt_status and populate in the collect phase

Status variables were initialized in the collect phase and some
variables were later freed in the print functions.

A "struct wt_status" used to be sufficient for the output phase to
work. It was designed to be filled in the collect phase and consumed
in the output phase, but over time some fields were added and output
phase started filling the fields.

A "struct wt_status_state" that was used in other codepaths turned out
to be useful in the "git status" output. This is not tied to "struct
wt_status", so filling in the collect phase was not consistently
followed.

Move the status state structure variables into the status state
structure and populate them in the collect functions.

Create a new function to free the buffers that were being freed in the
print function. Call this new function in commit.c where both the
collect and print functions were being called.

Based on a patch suggestion by Junio C Hamano. [1]

Recognize -r and --recursive as synonyms for --max-depth=-1 for

This also adds --no-recursive as synonym for --max-depth=0 for free,
which is welcome for completeness and consistency.

Fix the description for --max-depth, while we're at it -- negative
values other than -1 actually disable recursion, i.e. they are
equivalent to --max-depth=0.

help -a: improve and make --verbose default

When you type "git help" (or just "git") you are greeted with a list
with commonly used commands and their short description and are
suggested to use "git help -a" or "git help -g" for more details.

"git help -av" would be more friendly and inline with what is shown
with "git help" since it shows list of commands with description as
well, and commands are properly grouped.

"help -av" does not show everything "help -a" shows though. Add
external command section in "help -av" for this. While at there, add a
section for aliases as well (until now aliases have no UI, just "git

CodingGuidelines: document the API in *.h files

It makes it harder to let the API description and the reality drift
apart if the doc is kept close to the implementation or the header
of the API. We have been slowly migrating API docs out of the
Documentation/technical/api-* to *.h files, and the development
community generally considers that how inline docs in strbuf.h is
done the best current practice.

We recommend documenting in the header over documenting near the
implementation to encourage people to write the docs that are
readable without peeking at the implemention.

t7005-editor: quote filename to fix whitespace-issue

Commit 4362da078e (t7005-editor: get rid of the SPACES_IN_FILENAMES
prereq, 2018-05-14) removed code for detecting whether spaces in
filenames work. Since we rely on spaces throughout the test suite
("trash directory.t1234-foo"), testing whether we can use the filename
"e space.sh" was redundant and unnecessary.

In simplifying the code, though, this introduced a regression around how
spaces are handled, not in the /name/ of the editor script, but /in/ the
script itself. The script just does `echo space >$1`, where $1 is for
example "/foo/t/trash directory.t7005-editor/.git/COMMIT_EDITMSG".

With most shells, or with Bash in posix mode, $1 will not be subjected
to field splitting. But if we invoke Bash directly, which will happen if
we build Git with SHELL_PATH=/bin/bash, it will detect and complain
about an "ambiguous redirect". More details can be found in [1], thanks
to SZEDER Gábor.

Make sure that the editor script quotes "$1" to remove the ambiguity.

rev-parse: --show-superproject-working-tree should work during a merge

Invoking 'git rev-parse --show-superproject-working-tree' exits with

"fatal: BUG: returned path string doesn't match cwd?"

when the superproject has an unmerged entry for the current submodule,
instead of displaying the superproject's working tree.

The problem is due to the fact that when a merge of the submodule reference
is in progress, "git ls-files --stage —full-name <submodule-relative-path>”
returns three seperate entries for the submodule (one for each stage) rather
than a single entry; e.g.,

$ git ls-files --stage --full-name submodule-child-test
160000 dbbd2766fa330fa741ea59bb38689fcc2d283ac5 1 submodule-child-test

be returned; this patch makes it use the first entry if multiple entries
are returned.

t0000: do not get self-test disrupted by environment... Junio C Hamano Thu, 20 Sep 2018 18:43:43 +0000 (11:43 -0700)

t0000: do not get self-test disrupted by environment warnings

The test framework test-lib.sh itself would want to give warnings
and hints, e.g. when it sees a deprecated environment variable is in
use that we want to encourage users to migrate to another variable.

The self-test of test framework done in t0000 however do not expect
to see these warnings and hints, so depending on the settings of
environment variables, a running test may or may not produce these
messages to the standard error output, breaking the expectations of
self-test test framework does on itself. Here is what we see:

$ TEST_GIT_INDEX_VERSION=4 sh t0000-basic.sh -i -v
...
'err' is not empty, it contains:
warning: TEST_GIT_INDEX_VERSION is now GIT_TEST_INDEX_VERSION
hint: set GIT_TEST_INDEX_VERSION too during the transition period
not ok 5 - pretend we have a fully passing test suite

The following quick attempt to work it around does not work, because
some tests in t0000 do want to see expected errors from the test
framework itself.

t/t0000-basic.sh | 2 +-
1 file changed, 1 insertion(+), 1 deletion(-)

diff --git a/t/t0000-basic.sh b/t/t0000-basic.sh

+ . "\$TEST_DIRECTORY"/test-lib.sh >/dev/null 2>&1
EOF
cat >>"$name.sh" &&
chmod +x "$name.sh" &&

There are a few possible ways to work this around:

* We could strip the warning: and hint: unconditionally from the
error output before the error messages are checked in the
self-test (helper functions check_sub_test_lib_test_err and
check_sub_test_lib_test); the problem with this approach is that
it will make it impossible to write self-tests to ensure that
right warnings and hints are given.

* We could force a sane environment settings before the test helper
_run_sub_test_lib_test_common dot-sources test-lib.sh; the
problem with this approach is that _run_sub_test_lib_test_common
now needs to be aware of what pairs of environment variables are
checked in test-lib.sh using check_var_migration helper.

The final patch I came up with is probably the solution that is
least bad. Set a variable to tell test-lib.sh that we are running
a self-test, so that various pieces in test-lib.sh can react to keep
the output stable.

commit: fix erroneous BUG, 'multiple renames on the... Elijah Newren Thu, 27 Sep 2018 17:36:57 +0000 (10:36 -0700)

commit: fix erroneous BUG, 'multiple renames on the same target? how?'

builtin/commit.c:prepare_to_commit() can call run_status() twice if
using the editor, including status, and the user attempts to record a
non-merge empty commit without explicit --allow-empty. If there is also
a rename involved as well (due to using 'git add -N'), then a BUG in
wt-status.c is triggered:

BUG: wt-status.c:476: multiple renames on the same target? how?

The reason we hit this bug is that both run_status() calls use the same
struct wt_status * (named s), and s->change is not freed between runs.
Changes are inserted into s with string_list_insert, which usually means
that the second run just recomputes all the same results and overwrites
what was computed the first time. However, ever since commit
176ea7479309 ("wt-status.c: handle worktree renames", 2017-12-27),
wt-status started checking for renames and copies but also added a
preventative check that d->rename_status wasn't already set and output a
BUG message if it was. The problem isn't that there are multiple rename
targets to a single path as the error implies, the problem is that 's'
is not freed/cleared between the two run_status() calls.

Ever since commit dc6b1d92ca9c ("wt-status: use settings from
git_diff_ui_config", 2018-05-04), which stopped hardcoding
DIFF_DETECT_RENAME and allowed users to ask for copy detection, this bug
has also been triggerable with a copy instead of a rename.

Fix the bug by clearing s->change. A better change might be to clean up
all of s between the two run_status() calls. A good first step towards
such a goal might be writing a function to free the necessary fields in
the wt_status * struct; a cursory glance at the code suggests all of its
allocated data is probably leaked. However, doing all that cleanup is a
bigger task for someone else interested to tackle; just fix the bug for
now.

fsck: detect submodule paths starting with dash

As with urls, submodule paths with dashes are ignored by
git, but may end up confusing older versions. Detecting them
via fsck lets us prevent modern versions of git from being a
vector to spread broken .gitmodules to older versions.

Compared to blocking leading-dash urls, though, this
detection may be less of a good idea:

1. While such paths provide confusing and broken results,
they don't seem to actually work as option injections
against anything except "cd". In particular, the
submodule code seems to canonicalize to an absolute
path before running "git clone" (so it passes
/your/clone/-sub).

2. It's more likely that we may one day make such names
actually work correctly. Even after we revert this fsck
check, it will continue to be a hassle until hosting
servers are all updated.

On the other hand, it's not entirely clear that the behavior
in older versions is safe. And if we do want to eventually
allow this, we may end up doing so with a special syntax
anyway (e.g., writing "./-sub" in the .gitmodules file, and
teaching the submodule code to canonicalize it when
comparing).

So on balance, this is probably a good protection.

fsck: detect submodule urls starting with dash

Urls with leading dashes can cause mischief on older
versions of Git. We should detect them so that they can be
rejected by receive.fsckObjects, preventing modern versions
of git from being a vector by which attacks can spread.

submodule-config: ban submodule paths that start with a dash

We recently banned submodule urls that look like
command-line options. This is the matching change to ban
leading-dash paths.

As with the urls, this should not break any use cases that
currently work. Even with our "--" separator passed to
git-clone, git-submodule.sh gets confused. Without the code
portion of this patch, the clone of "-sub" added in t7417
would yield results like:

/path/to/git-submodule: 410: cd: Illegal option -s
/path/to/git-submodule: 417: cd: Illegal option -s
/path/to/git-submodule: 410: cd: Illegal option -s
/path/to/git-submodule: 417: cd: Illegal option -s
Fetched in submodule path '-sub', but it did not contain b56243f8f4eb91b2f1f8109452e659f14dd3fbe4. Direct fetching of that commit failed.

Moreover, naively adding such a submodule doesn't work:

$ git submodule add $url -sub
The following path is ignored by one of your .gitignore files:
-sub

even though there is no such ignore pattern (the test script
hacks around this with a well-placed "git mv").

Unlike leading-dash urls, though, it's possible that such a
path _could_ be useful if we eventually made it work. So
this commit should be seen not as recommending a particular
policy, but rather temporarily closing off a broken and
possibly dangerous code-path. We may revisit this decision
later.

There are two minor differences to the tests in t7416 (that
covered urls):

1. We don't have a "./-sub" escape hatch to make this
work, since the submodule code expects to be able to
match canonical index names to the path field (so you
are free to add submodule config with that path, but we
would never actually use it, since an index entry would
never start with "./").

2. After this patch, cloning actually succeeds. Since we
ignore the submodule.*.path value, we fail to find a
config stanza for our submodule at all, and simply
treat it as inactive. We still check for the "ignoring"
message.

submodule-config: ban submodule urls that start with dash

The previous commit taught the submodule code to invoke our
"git clone $url $path" with a "--" separator so that we
aren't confused by urls or paths that start with dashes.

However, that's just one code path. It's not clear if there
are others, and it would be an easy mistake to add one in
the future. Moreover, even with the fix in the previous
commit, it's quite hard to actually do anything useful with
such an entry. Any url starting with a dash must fall into
one of three categories:

- it's meant as a file url, like "-path". But then any
clone is not going to have the matching path, since it's
by definition relative inside the newly created clone. If
you spell it as "./-path", the submodule code sees the
"/" and translates this to an absolute path, so it at
least works (assuming the receiver has the same
filesystem layout as you). But that trick does not apply
for a bare "-path".

- it's meant as an ssh url, like "-host:path". But this
already doesn't work, as we explicitly disallow ssh
hostnames that begin with a dash (to avoid option
injection against ssh).

- it's a remote-helper scheme, like "-scheme::data". This
_could_ work if the receiver bends over backwards and
creates a funny-named helper like "git-remote--scheme".
But normally there would not be any helper that matches.

Since such a url does not work today and is not likely to do
anything useful in the future, let's simply disallow them
entirely. That protects the existing "git clone" path (in a
belt-and-suspenders way), along with any others that might
exist.

Our tests cover two cases:

1. A file url with "./" continues to work, showing that
there's an escape hatch for people with truly silly
repo names.

2. A url starting with "-" is rejected.

Note that we expect case (2) to fail, but it would have done
so even without this commit, for the reasons given above.
So instead of just expecting failure, let's also check for
the magic word "ignoring" on stderr. That lets us know that
we failed for the right reason.

submodule--helper: use "--" to signal end of clone options

When we clone a submodule, we call "git clone $url $path".
But there's nothing to say that those components can't begin
with a dash themselves, confusing git-clone into thinking
they're options. Let's pass "--" to make it clear what we
expect.

There's no test here, because it's actually quite hard to
make these names work, even with "git clone" parsing them
correctly. And we're going to restrict these cases even
further in future commits. So we'll leave off testing until
then; this is just the minimal fix to prevent us from doing
something stupid with a badly formed entry.

read-cache.c: optimize reading index format v4Nguyễn Thái Ngọc Duy Wed, 26 Sep 2018 19:54:36 +0000 (15:54 -0400)

read-cache.c: optimize reading index format v4

Index format v4 requires some more computation to assemble a path
based on a previous one. The current code is not very efficient
because

- it doubles memory copy, we assemble the final path in a temporary
first before putting it back to a cache_entry

- strbuf_remove() in expand_name_field() is not exactly a good fit
for stripping a part at the end, _setlen() would do the same job
and is much cheaper.

- the open-coded loop to find the end of the string in
expand_name_field() can't beat an optimized strlen()

This patch avoids the temporary buffer and writes directly to the new
cache_entry, which addresses the first two points. The last point
could also be avoided if the total string length fits in the first 12
bits of ce_flags, if not we fall back to strlen().

Running "test-tool read-cache 100" on webkit.git (275k files), reading
v2 only takes 4.226 seconds, while v4 takes 5.711 seconds, 35% more
time. The patch reduces read time on v4 to 4.319 seconds.

In t5551 we check that we save cookies correctly to a file when

expect file that expects the cookies in a certain order.

However after e2ef8d6fa ("cookies: support creation-time attribute for
cookies", 2018-08-28) in curl.git (released in curl 7.61.1) that order
changed.

We document the file format as "Netscape/Mozilla cookie file
format (see curl(1))", so any format produced by libcurl should be
fine here. Sort the files, to be agnostic to the order of the
cookies, and make the test pass with both curl versions > 7.61.1 and
earlier curl versions.

fetch: in partial clone, check presence of targets

When fetching an object that is known as a promisor object to the local
repository, the connectivity check in quickfetch() in builtin/fetch.c
succeeds, causing object transfer to be bypassed. However, this should
not happen if that object is merely promised and not actually present.

Because this happens, when a user invokes "git fetch origin <sha-1>" on
the command-line, the <sha-1> object may not actually be fetched even
though the command returns an exit code of 0. This is a similar issue
(but with a different cause) to the one fixed by a0c9016abd
("upload-pack: send refs' objects despite "filter"", 2018-07-09).

Therefore, update quickfetch() to also directly check for the presence
of all objects to be fetched. Its documentation and name are also
updated to better reflect what it does.

The can_all_from_reach_with_flag() method uses 'assign_flag' as a
value we can use to mark objects temporarily during our commit walk.
The intent is that these flags are removed from all objects before
returning. However, this is not the case.

The 'from' array could also contain objects that are not commits, and
we mark those objects with 'assign_flag'. Add a loop to the 'cleanup'
section that removes these markers.

Also, we forgot to free() the memory for 'list', so add that to the
'cleanup' section.

The can_all_from_reach_with_flag() algorithm was refactored in 4fbcca4e
"commit-reach: make can_all_from_reach... linear" but incorrectly
assumed that all objects provided were commits. During a fetch
negotiation, ok_to_give_up() in upload-pack.c may provide unpeeled tags
to the 'from' array. The current code creates a segfault.

Add a direct call to can_all_from_reach_with_flag() in 'test-tool reach'
and add a test in t6600-test-reach.sh that demonstrates this segfault.

rerere.c: remove implicit dependency on the_index

The reason rerere(), rerere_forget() and rerere_remaining() take a
struct repository instead of struct index_state is not obvious from
the patch:

Deep in update_paths() and find_conflict(), hold_locked_index() and
read_index() are called. These functions assumes the index path at
$GIT_DIR/index which is not always true when you take an arbitrary
index state. Taking a repository will allow us to point to the right
index path later when we replace them with repo_ versions.

diff.c: reduce implicit dependency on the_index

diff and textconv code has so widespread use that it's hard to simply

a big patch. For now reduce the_index references to two places:
diff_setup() and fill_textconv().

read-cache.c: remove 'const' from index_has_changes()Nguyễn Thái Ngọc Duy Fri, 21 Sep 2018 15:57:18 +0000 (17:57 +0200)

read-cache.c: remove 'const' from index_has_changes()

This function calls do_diff_cache() which eventually needs to set this
"istate" to unpack_options->src_index [1]. This is an unfortunate fact
that unpack_trees() _will_ update [2] src_index so we can't really pass a
const index_state there. Just remove 'const'.

[1] Right now diff_cache() in diff-lib.c assigns the_index to
src_index. But the plan is to get rid of the_index, so it should
be 'istate' from here that gets assigned to src_index.

[2] Some transient bits in the source index are touched. Optional
extensions can also be removed. But other than that the source
tree should still be valid.

completion: support "git fetch --multiple"

When --multiple is given, the remaining arguments are remote names,
not one remote followed by zero or more refspec. Detect this case,
disable refspec completion, and pretend no remote is seen in order to
complete multiple of them.

add: do not accept pathspec magic 'attr'Nguyễn Thái Ngọc Duy Tue, 18 Sep 2018 17:31:59 +0000 (19:31 +0200)

add: do not accept pathspec magic 'attr'

Commit b0db704652 (pathspec: allow querying for attributes -
2017-03-13) adds new pathspec magic 'attr' but only with
match_pathspec(). "git add" has some pathspec related code that still
does not know about 'attr' and will bail out:

$ git add ':(attr:foo)'
fatal: BUG:dir.c:1584: unsupported magic 40

A better solution would be making this code support 'attr'. But I
don't know how much work is needed (I'm not familiar with this new
magic). For now, let's simply reject this magic with a friendlier
message:

$ git add ':(attr:foo)'
fatal: :(attr:foo): pathspec magic not supported by this command: 'attr'

Update t6135 so that the expected error message is from the
"graceful" rejection codepath, not "oops, we were supposed to reject
the request to trigger this magic" codepath.
