SZEDER Gábor d45cec4bea test-lib: translate SIGTERM and SIGHUP to an exit
Right now if a test script receives SIGTERM or SIGHUP (e.g., because a
test was hanging and the user 'kill'-ed it or simply closed the
terminal window the test was running in), the shell exits 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.

Instead, let's trap SIGTERM and SIGHUP as well to make sure we do a
clean shutdown, and just chain it to a normal exit (which will trigger
any cleanup).

This patch follows suit of da706545f7 (t: translate SIGINT to an exit,
2015-03-13), and even stole its commit message as well.

  test-lib: check Bash version for '-x' without using shell arrays
2019-01-03 13:18:55 -08:00
SZEDER Gábor 5826b7b595 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.

Chayoung You 6d54f528c7 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/'.

Chayoung You 7a478b36aa 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.

Erin Dahlgren 07098b81a4 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().

Derrick Stolee cce99cd8c6 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.

Thomas Gummerer f24eaf4a21 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.

Martin Ågren b62eb1d2f4 git-status.txt: render tables correctly under Asciidoctor

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

Torsten Bögershausen 1cadad6f65 git clone <url> C:\cygwin\home\USER\repo' is working (again)
A regression for cygwin users was introduced with commit 05b458c,
 "real_path: resolve symlinks by hand".

In the the commit message we read:
  The current implementation of real_path uses chdir() in order to resolve
    symlinks.  Unfortunately this isn't thread-safe as chdir() affects a
      process as a whole...

The old (and non-thread-save) OS calls chdir()/pwd() had been
replaced by a string operation.
The cygwin layer "knows" that "C:\cygwin" is an absolute path,
but the new string operation does not.

"git clone <url> C:\cygwin\home\USER\repo" fails like this:
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.

  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]

  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.

Sergey Organov 37897bfc27 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.

Sergey Organov c812bd4669 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.

Stefan Beller 8eda5efa12 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.

Stefan Beller 898c2e65b7 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.

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.

Derrick Stolee fc767afe77 .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
for the send-email test case in t9902.
