It is a common mistake to put positional arguments before flags when
invoking git-rev-list. Order the positional arguments last.
This patch skips git-rev-list invocations which include the --not flag,
since the ordering of flags and positional arguments affects the
behavior. This patch also skips invocations of git-rev-list that occur
in command substitution in which the exit code is discarded, since
fixing those properly will require a more involved cleanup.

Instead of using a line-continuation and pipe on the second line, take
advantage of the shell's implicit line continuation after a pipe
character. So for example, instead of
some long line \

use
some long line |
next line
And add a blank line before and after the pipe where it aids readability
(it usually does).
This better matches the coding style documented in

The list of Don'ts for test writing has grown large such that it is hard
to see at a glance which section an item is in. In other words, if I
ignore a little bit of surrounding context, the "don'ts" look like
"do's."
To make the list more readable, prefix "Don't" in front of every first
sentence in the items.
Also, the "Keep in mind" list is out of place and awkward, because it
was a very short "list" beneath two very long ones, and it seemed easy
to miss under the list of "don'ts," and it only had one item. So move
this item to the list of "do's" and phrase as "Remember..."

Quite some time ago, a last plea to the XP users out there who want to
see Windows XP support in Git for Windows, asking them to get engaged
and help, vanished into the depths of the universe.
We tried for a long time to play nice with the last remaining XP users
who somehow manage to build Git from source, but a recent update of
mingw-w64 (7.0.0.5233.e0c09544 -> 7.0.0.5245.edf66197) finally dropped
the last sign of XP support, and Git for Windows' SDK is no longer able
to build core Git's `master` branch as a consequence. (Git for Windows'
`master` branch already bumped the minimum Windows version to Vista a
while ago, so it is fine.)
It is time to require Windows Vista or later to build Git from source.
This, incidentally, lets us use quite a few nice new APIs.

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.

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.
# Point to the t/test-lib.sh, which isn't in ../ as usual
- . "\$TEST_DIRECTORY"/test-lib.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 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.

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.

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.

mailmap: consistently normalize brian m. carlson's name
v2.18.0-rc0~70^2 (mailmap: update brian m. carlson's email address,
2018-05-08) changed the mailmap to map
sandals@crustytoothpaste.ath.cx
-> brian m. carlson <sandals@crustytoothpaste.net>
instead of
sandals@crustytoothpaste.net
-> brian m. carlson <sandals@crustytoothpaste.ath.cx>
That means the mapping
Brian M. Carlson <sandals@crustytoothpaste.ath.cx>
-> brian m. carlson <sandals@crustytoothpaste.net>
is redundant, so we can remove it. More importantly, it means that
the identity "Brian M. Carlson <sandals@crustytoothpaste.net>" used in
some commits is not normalized any more. Add a mapping for it.
Noticed while updating Debian's Git packaging, which uses "git
shortlog --no-merges" to produce a list of changes in each version,
grouped by author's (normalized) name.

Due to a regression introduced by 4fbcca4e "commit-reach: make
can_all_from_reach... linear" the series including b67f6b26
"commit-reach: properly peel tags" was merged to master quickly.
There were a few more cleanups left to apply in the series, which
are included by this change:
1. Clean up a comment that is in the incorrect style.
2. Replace multiple calls to clear_commit_marks() with one call to
clear_commit_marks_many().

"git add ':(attr:foo)'" is not supported and is supposed to be
rejected while the command line arguments are parsed, but we fail
to reject such a command line upfront.
