Earlier we added "-Wformat-security" to developer builds, assuming

fixed by unconditionally adding "-Wall" to developer builds.

Merge branch 'so/cherry-pick-always-allow-m1'

"git cherry-pick -m1" was forbidden when picking a non-merge
commit, even though there _is_ parent number 1 for such a commit.
This was done to avoid mistakes back when "cherry-pick" was about
picking a single commit, but is no longer useful with "cherry-pick"
that can pick a range of commits. Now the "-m$num" option is
allowed when picking any commit, as long as $num names an existing
parent of the commit.

Technically this is a backward incompatible change; hopefully
nobody is relying on the error-checking behaviour.

worktree: allow to (re)move worktrees with uninitialize... Nguyễn Thái Ngọc Duy Sat, 5 Jan 2019 05:08:40 +0000 (12:08 +0700)

worktree: allow to (re)move worktrees with uninitialized submodules

Uninitialized submodules have nothing valueable for us to be worried
about. They are just SHA-1. Let "worktree remove" and "worktree move"
continue in this case so that people can still use multiple worktrees
on repos with optional submodules that are never populated, like
sha1collisiondetection in git.git when checked out by doc-diff script.

Note that for "worktree remove", it is possible that a user
initializes a submodule (*), makes some commits (but not push), then
deinitializes it. At that point, the submodule is unpopulated, but the
precious new commits are still in

$GIT_COMMON_DIR/worktrees/<worktree>/modules/<submodule>

directory and we should not allow removing the worktree or we lose
those commits forever. The new directory check is added to prevent
this.

(*) yes they are screwed anyway by doing this since "git submodule"
would add submodule.* in $GIT_COMMON_DIR/config, which is shared
across multiple worktrees. But it does not mean we let them be
screwed even more.

config.mak.dev: add -Wall, primarily for -Wformat, to help autoconf users

801fa63a90 ("config.mak.dev: add -Wformat-security", 2018-09-08)
added the "-Wformat-security" to the flags set in config.mak.dev.
In the gcc man page this is documented as:

If -Wformat is specified, also warn about uses of format
functions that represent possible security problems. [...]

The commit did however not add the "-Wformat" flag, but instead
relied on the fact that "-Wall" is set in the Makefile by default
and that "-Wformat" is part of "-Wall".

Unfortunately, those who use config.mak.autogen generated with the
autoconf to configure toolchain do *not* get "-Wall" in their CFLAGS
and the added -Wformat-security had no effect. Worse yet, newer
versions of gcc (gcc 8.2.1 in this particular case) warn about the
lack of "-Wformat" and thus compilation fails only with this option
set.

We could fix it by adding "-Wformat", but in general we do want all
checks included in "-Wall", so let's add it to config.mak.dev to
cover more cases.

Revert "t/lib-git-daemon: record daemon log"Thomas Gummerer Sun, 6 Jan 2019 17:53:10 +0000 (17:53 +0000)

Revert "t/lib-git-daemon: record daemon log"

This reverts commit 314a73d658 (t/lib-git-daemon: record daemon log,
2018-01-25), which let tests use the output of git-daemon.

The previous commit removed the last user of deamon.log in the tests,
there's no good way to make checking for output in the log
race-proof. Revert this commit as well, to make sure others are not
tempted to use daemon.log in tests in the future, which would lead to
racy tests.

The original commit had one change that still makes sense, namely
switching read/echo for "read -r" and "printf", which relays the data
more faithfully. Don't revert that piece here, as it is still a
useful change.

test-lib: check Bash version for '-x' without using shell arrays

test-lib: check Bash version for '-x' without using... SZEDER Gábor Thu, 3 Jan 2019 11:43:17 +0000 (12:43 +0100)

test-lib: check Bash version for '-x' without using shell arrays

One of our test scripts, 't1510-repo-setup.sh' [1], still can't be
reliably run with '-x' tracing enabled, unless it's executed with a
Bash version supporting BASH_XTRACEFD (since v4.1). We have a lengthy
condition to check the version of the shell running the test script,
and disable tracing if it's not executed with a suitable Bash version
[2].

This condition uses non-portable shell array accesses to easily get
Bash's major and minor version number. This didn't seem to be
problematic, because the simple commands expanding those array
accesses are only executed when the test script is actually run with
Bash. When run with Dash, the only shell I have at hand that doesn't
support shell arrays, there are no issues, as it apparently skips
right over the non-executed simple commands without noticing the
non-supported constructs.

Alas, it has been reported that NetBSD's /bin/sh does complain about
them:

./test-lib.sh: 327: Syntax error: Bad substitution

where line 327 contains the first ${BASH_VERSINFO[0]} array access.

To my understanding both shells are right and conform to POSIX,
because the standard allows both behaviors by stating the following
under '2.8.1 Consequences of Shell Errors' [3]:

"An expansion error is one that occurs when the shell expansions
define in wordexp are carried out (for example, "${x!y}", because
'!' is not a valid operator); an implementation may treat these as
syntax errors if it is able to detect them during tokenization,
rather than during expansion."

Avoid this issue with NetBSD's /bin/sh (and potentially with other,
less common shells) by hiding the shell array syntax behind 'eval'
that is only executed with Bash.

completion: treat results of git ls-tree as file pathsChayoung You Tue, 1 Jan 2019 14:05:09 +0000 (23:05 +0900)

completion: treat results of git ls-tree as file paths

Let's say there are files named 'foo bar.txt', and 'abc def/test.txt' in
repository. When following commands trigger a completion:

git show HEAD:fo<Tab>
git show HEAD:ab<Tab>

The completion results in bash/zsh:

git show HEAD:foo bar.txt
git show HEAD:abc def/

Where the both of them have an unescaped space in paths, so they'll be
misread by git. All entries of git ls-tree either a filename or a
directory, so __gitcomp_file() is proper rather than __gitcomp_nl().

Note the commit f12785a3, which handles quoted paths properly. Like this
case, we should dequote $cur_ for ?*:* case. For example, let's say
there is untracked directory 'abc deg', then trigger a completion:

git show HEAD:abc\ de<Tab>
git show HEAD:'abc de<Tab>
git show HEAD:"abc de<Tab>

should uniquely complete 'abc def', but bash completes 'abc def' and
'abc deg' instead. In zsh, triggering a completion:

git show HEAD:abc\ def/<Tab>

should complete 'test.txt', but nothing comes. The both problems will be
resolved by dequoting paths.

__git_complete_revlist_file() passes arguments to __gitcomp_nl() where
the first one is a list something like:

abc def/Z
foo bar.txt Z

where Z is the mark of the EOL.

- The trailing space of blob in __git ls-tree | sed.
It makes the completion results become:

git show HEAD:foo\ bar.txt\ <CURSOR>

So git will try to find a file named 'foo bar.txt ' instead.

- The trailing slash of tree in __git ls-tree | sed.
It makes the completion results on zsh become:

git show HEAD:abc\ def/ <CURSOR>

So that the last space on command like should be removed on zsh to
complete filenames under 'abc def/'.

zsh: complete unquoted paths with spaces correctlyChayoung You Tue, 1 Jan 2019 14:05:08 +0000 (23:05 +0900)

zsh: complete unquoted paths with spaces correctly

The following is the description of -Q flag of zsh compadd [1]:

This flag instructs the completion code not to quote any
metacharacters in the words when inserting them into the command
line.

Let's say there is a file named 'foo bar.txt' in repository, but it's
not yet added to the repository. Then the following command triggers a
completion:

git add fo<Tab>
git add 'fo<Tab>
git add "fo<Tab>

The completion results in bash:

git add foo\ bar.txt
git add 'foo bar.txt'
git add "foo bar.txt"

While them in zsh:

git add foo bar.txt
git add 'foo bar.txt'
git add "foo bar.txt"

The first one, where the pathname is not enclosed in quotes, should
escape the space with a backslash, just like bash completion does.
Otherwise, this leads git to think there are two files; foo, and
bar.txt.

The main cause of this behavior is __gitcomp_file_direct(). The both
implementions of bash and zsh are called with an argument 'foo bar.txt',
but only bash adds a backslash before a space on command line.

Simplify handling of setup_git_directory_gently() failu... Erin Dahlgren Thu, 27 Dec 2018 23:36:29 +0000 (15:36 -0800)

Simplify handling of setup_git_directory_gently() failure cases.

setup_git_directory_gently() expects two types of failures to
discover a git directory (e.g. .git/):

- GIT_DIR_HIT_CEILING: could not find a git directory in any
parent directories of the cwd.
- GIT_DIR_HIT_MOUNT_POINT: could not find a git directory in
any parent directories up to the mount point of the cwd.

Both cases are handled in a similar way, but there are misleading
and unimportant differences. In both cases, setup_git_directory_gently()
should:

- Die if we are not in a git repository. Otherwise:
- Set nongit_ok = 1, indicating that we are not in a git repository
but this is ok.
- Call strbuf_release() on any non-static struct strbufs that we
allocated.

Before this change are two misleading additional behaviors:

- GIT_DIR_HIT_CEILING: setup_nongit() changes to the cwd for no
apparent reason. We never had the chance to change directories
up to this point so chdir(current cwd) is pointless.
- GIT_DIR_HIT_MOUNT_POINT: strbuf_release() frees the buffer
of a static struct strbuf (cwd). This is unnecessary because the
struct is static so its buffer is always reachable. This is also
misleading because nowhere else in the function is this buffer
released.

This change eliminates these two misleading additional behaviors and
deletes setup_nogit() because the code is clearer without it. The
result is that we can see clearly that GIT_DIR_HIT_CEILING and
GIT_DIR_HIT_MOUNT_POINT lead to the same behavior (ignoring the
different help messages).

During review, this change was amended to additionally include:

- Neither GIT_DIR_HIT_CEILING nor GIT_DIR_HIT_MOUNT_POINT may
return early from setup_git_directory_gently() before the
GIT_PREFIX environment variable is reset. Change both cases to
break instead of return. See GIT_PREFIX below for more details.

- GIT_DIR_NONE: setup_git_directory_gently_1() never returns this
value, but if it ever did, setup_git_directory_gently() would
incorrectly record that it had found a repository. Explicitly
BUG on this case because it is underspecified.

- GIT_PREFIX: this environment variable must always match the
value of startup_info->prefix and the prefix returned from
setup_git_directory_gently(). Make how we handle this slightly
more repetitive but also more clear.

- setup_git_env() and repo_set_hash_algo(): Add comments showing
that only GIT_DIR_EXPLICIT, GIT_DIR_DISCOVERED, and GIT_DIR_BARE
will cause setup_git_directory_gently() to call these setup
functions. This was obvious (but partly incorrect) before this
change when GIT_DIR_HIT_MOUNT_POINT returned early from
setup_git_directory_gently().

commit-graph: writing missing parents is a BUGDerrick Stolee Wed, 19 Dec 2018 20:14:07 +0000 (12:14 -0800)

commit-graph: writing missing parents is a BUG

When writing a commit-graph, we write GRAPH_MISSING_PARENT if the
parent's object id does not appear in the list of commits to be
written into the commit-graph. This was done as the initial design
allowed commits to have missing parents, but the final version
requires the commit-graph to be closed under reachability. Thus,
this GRAPH_MISSING_PARENT value should never be written.

However, there are reasons why it could be written! These range
from a bug in the reachable-closure code to a memory error causing
the binary search into the list of object ids to fail. In either
case, we should fail fast and avoid writing the commit-graph file
with bad data.

Remove the GRAPH_MISSING_PARENT constant in favor of the constant
GRAPH_EDGE_LAST_MASK, which has the same value.

t5570: drop racy test

t5570 being racy has been reported twice separately on the mailing
list [*1*, *2*].

To make the test race proof, we'd either have to introduce another
fifo the test snippet is waiting on, or somehow convincing "cat" to
flush (and let us know when it has). Which really implies killing the
daemon, and wait()ing on cat to process the EOF and exit. And that
makes the tests a lot more expensive if we have to start the daemon
for each snippet.

As this is a test for a relatively minor fix (according to the author)
in 19136be3f8 ("daemon: fix off-by-one in logging extended
attributes", 2018-01-24), drop it to avoid this racyness. It doesn't
seem worth making the test code much more complex, or slowing down all
tests just to keep this one.

git-status.txt: render tables correctly under Asciidoctor

Asciidoctor removes the indentation of each line in these tables, so the
last lines of each table have a completely broken alignment.

Similar to 379805051d ("Documentation: render revisions correctly under
Asciidoctor", 2018-05-06), use an explicit literal block to indicate
that we want to keep the leading whitespace in the tables.

Because this gives us some extra indentation, we can remove the one that
we have been carrying explicitly. That is, drop the first four spaces of
indentation on each line. With Asciidoc (8.6.10), this results in
identical rendering before and after this commit, both for git-status.1

fatal: Invalid path '/home/USER/repo/C:\cygwin\home\USER\repo'

The solution is to implement has_dos_drive_prefix(), skip_dos_drive_prefix()
is_dir_sep(), offset_1st_component() and convert_slashes() for cygwin
in the same way as it is done in 'Git for Windows' in compat/mingw.[ch]

Extract the needed code into compat/win32/path-utils.[ch] and use it
for cygwin as well.

log -G: ignore binary filesThomas Braun Fri, 14 Dec 2018 18:49:12 +0000 (19:49 +0100)

log -G: ignore binary files

The -G<regex> option of log looks for the differences whose patch text
contains added/removed lines that match regex.

Currently -G looks also into patches of binary files (which
according to [1]) is binary as well.

This has a couple of issues:

- It makes the pickaxe search slow. In a proprietary repository of the
author with only ~5500 commits and a total .git size of ~300MB
searching takes ~13 seconds

$time git log -Gwave > /dev/null

real 0m13,241s
user 0m12,596s
sys 0m0,644s

whereas when we ignore binary files with this patch it takes ~4s

$time ~/devel/git/git log -Gwave > /dev/null

real 0m3,713s
user 0m3,608s
sys 0m0,105s

which is a speedup of more than fourfold.

- The internally used algorithm for generating patch text is based on
xdiff and its states in [1]

> The output format of the binary patch file is proprietary
> (and binary) and it is basically a collection of copy and insert
> commands [..]

which means that the current format could change once the internal
algorithm is changed as the format is not standardized. In addition
the git binary patch format used for preparing patches for git apply
is *different* from the xdiff format as can be seen by comparing

which seems unexpected.

To resolve these issues this patch makes -G<regex> ignore binary files
by default. Textconv filters are supported and also -a/--text for
getting the old and broken behaviour back.

The -S<block of text> option of log looks for differences that changes
the number of occurrences of the specified block of text (i.e.
addition/deletion) in a file. As we want to keep the current behaviour,
add a test to ensure it stays that way.

cherry-pick: do not error on non-merge commits when... Sergey Organov Fri, 14 Dec 2018 04:53:51 +0000 (07:53 +0300)

cherry-pick: do not error on non-merge commits when '-m 1' is specified

When cherry-picking multiple commits, it's impossible to have both
merge- and non-merge commits on the same command-line. Not specifying
'-m 1' results in cherry-pick refusing to handle merge commits, while
specifying '-m 1' fails on non-merge commits.

This patch allows '-m 1' for non-merge commits. As mainline is always
the only parent for a non-merge commit, it makes little sense to
disable it.

t3510: stop using '-m 1' to force failure mid-sequence of cherry-picks

We are going to allow 'git cherry-pick -m 1' for non-merge commits, so
this method to force failure will stop to work.

Use '-m 4' instead as it's very unlikely we will ever have such an
octopus in this test setup.

submodule deinit: unset core.worktreeStefan Beller Fri, 14 Dec 2018 23:59:45 +0000 (15:59 -0800)

submodule deinit: unset core.worktree

When a submodule is deinit'd, the working tree is gone, so the setting of
core.worktree is bogus. Unset it. As we covered the only other case in
which a submodule loses its working tree in the earlier step
(i.e. switching branches of top-level project to move to a commit that did
not have the submodule), this makes the code always maintain
core.worktree correctly unset when there is no working tree
for a submodule.

This re-introduces 984cd77ddb (submodule deinit: unset core.worktree,
2018-06-18), which was reverted as part of f178c13fda (Revert "Merge
branch 'sb/submodule-core-worktree'", 2018-09-07)

The whole series was reverted as the offending commit e98317508c
(submodule: ensure core.worktree is set after update, 2018-06-18)
was relied on by other commits such as 984cd77ddb.

Keep the offending commit reverted, but its functionality came back via
4d6d6ef1fc (Merge branch 'sb/submodule-update-in-c', 2018-09-17), such
that we can reintroduce 984cd77ddb now.

submodule: unset core.worktree if no working tree is... Stefan Beller Fri, 14 Dec 2018 23:59:43 +0000 (15:59 -0800)

submodule: unset core.worktree if no working tree is present

When a submodules work tree is removed, we should unset its core.worktree
setting as the worktree is no longer present. This is not just in line
with the conceptual view of submodules, but it fixes an inconvenience
for looking at submodules that are not checked out:

git clone --recurse-submodules git://github.com/git/git && cd git &&
git checkout --recurse-submodules v2.13.0
git -C .git/modules/sha1collisiondetection log
fatal: cannot chdir to '../../../sha1collisiondetection': \
No such file or directory

With this patch applied, the final call to git log works instead of dying
in its setup, as the checkout will unset the core.worktree setting such
that following log will be run in a bare repository.

This patch covers all commands that are in the unpack machinery, i.e.
checkout, read-tree, reset. A follow up patch will address
"git submodule deinit", which will also make use of the new function
submodule_unset_core_worktree(), which is why we expose it in this patch.

This patch was authored as 4fa4f90ccd (submodule: unset core.worktree if
no working tree is present, 2018-06-12), which was reverted as part of
f178c13fda (Revert "Merge branch 'sb/submodule-core-worktree'",
2018-09-07). The revert was needed as the nearby commit e98317508c
(submodule: ensure core.worktree is set after update, 2018-06-18) is
faulty and at the time of 7e25437d35 (Merge branch
'sb/submodule-core-worktree', 2018-07-18) we could not revert the faulty
commit only, as they were depending on each other: If core.worktree is
unset, we have to have ways to ensure that it is set again once
the working tree reappears again.

Now that 4d6d6ef1fc (Merge branch 'sb/submodule-update-in-c', 2018-09-17),
specifically 74d4731da1 (submodule--helper: replace
connect-gitdir-workingtree by ensure-core-worktree, 2018-08-13) is
present, we already check and ensure core.worktree is set when
populating a new work tree, such that we can re-introduce the commits
that unset core.worktree when removing the worktree.

submodule update: add regression test with old style... Stefan Beller Fri, 14 Dec 2018 23:59:42 +0000 (15:59 -0800)

submodule update: add regression test with old style setups

As f178c13fda (Revert "Merge branch 'sb/submodule-core-worktree'",
2018-09-07) was produced shortly before a release, nobody asked for
a regression test to be included. Add a regression test that makes sure
that the invocation of `git submodule update` on old setups doesn't
produce errors as pointed out in f178c13fda.

The place to add such a regression test may look odd in t7412, but
that is the best place as there we setup old style submodule setups
explicitly.

.gitattributes: ensure t/oid-info/* has eol=lf

The new test_oid machinery in the test library requires reading
some information from t/oid-info/hash-info and t/oid-info/oid.

The logic to read from these files in shell uses built-in "read"
command, which leaves CR at the end of these text files when they
are checked out with CRLF line endings, at least when run with bash
shipped with Git for Windows. This results in an unexpected value
in the variable these lines are read into, leading the tests to
fail.

Mark them to be checked out always with the LF line endings.

The oneline notwithstanding, 13374987dd (completion: use _gitcompbuiltin

are completed, by asking the git send-email command itself what options
it offers.

Necessarily, this must fail when built with NO_PERL because send-email
itself is a Perl script. Which means that we need the PERL prerequisite
