Merge branch 'tb/apply-with-crlf' into next

"git apply" that is used as a better "patch -p1" failed to apply a
taken from a file with CRLF line endings to a file with CRLF line
endings. The root cause was because it misused convert_to_git()
that tried to do "safe-crlf" processing by looking at the index
entry at the same path, which is a nonsense---in that mode, "apply"
is not working on the data in (or derived from) the index at all.
This has been fixed.

apply: file commited with CRLF should roundtrip diff... Torsten Bögershausen Sat, 19 Aug 2017 11:28:01 +0000 (13:28 +0200)

apply: file commited with CRLF should roundtrip diff and apply

When a file had been commited with CRLF but now .gitattributes say
"* text=auto" (or core.autocrlf is true), the following does not
roundtrip, `git apply` fails:

printf "Added line\r\n" >>file &&
git diff >patch &&
git checkout -- . &&
git apply patch

Before applying the patch, the file from working tree is converted
into the index format (clean filter, CRLF conversion, ...). Here,
when commited with CRLF, the line endings should not be converted.

Note that `git apply --index` or `git apply --cache` doesn't call
convert_to_git() because the source material is already in index
format.

Analyze the patch if there is a) any context line with CRLF, or b)
if any line with CRLF is to be removed. In this case the patch file
`patch` has mixed line endings, for a) it looks like this:

diff --git a/one b/one
index 533790e..c30dea8 100644
--- a/one
+++ b/one
@@ -1 +1,2 @@
a\r
+b\r

And for b) it looks like this:

diff --git a/one b/one
index 533790e..485540d 100644
--- a/one
+++ b/one
@@ -1 +1 @@
-a\r
+b\r

If `git apply` detects that the patch itself has CRLF, (look at the
line " a\r" or "-a\r" above), the new flag crlf_in_old is set in
"struct patch" and two things will happen:

- read_old_data() will not convert CRLF into LF by calling
convert_to_git(..., SAFE_CRLF_KEEP_CRLF);
- The WS_CR_AT_EOL bit is set in the "white space rule",
CRLF are no longer treated as white space.

While at there, make it clear that read_old_data() in apply.c knows
what it wants convert_to_git() to do with respect to CRLF. In fact,
this codepath is about applying a patch to a file in the filesystem,
which may not exist in the index, or may exist but may not match
what is recorded in the index, or in the extreme case, we may not
even be in a Git repository. If convert_to_git() peeked at the
index while doing its work, it *would* be a bug.

Pass NULL instead of &the_index to convert_to_git() to make sure we
catch future bugs to clarify this.

Update the test in t4124: split one test case into 3:

- Detect the " a\r" line in the patch
- Detect the "-a\r" line in the patch
- Use LF in repo and CLRF in the worktree.

commit: rewrite read_graft_linePatryk Obara Fri, 18 Aug 2017 18:33:14 +0000 (20:33 +0200)

commit: rewrite read_graft_line

Old implementation determined number of hashes by dividing length of
line by length of hash, which works only if all hash representations
have same length.

New graft line parser works in two phases:

1. In first phase line is scanned to verify correctness and compute
number of hashes, then graft struct is allocated.

2. In second phase line is scanned again to fill up already allocated
graft struct.

This way graft parsing code can support different sizes of hashes
without any further code adaptations.

A number of alternative implementations were considered and discarded:

- Modifying graft structure to store oid_array instead of FLEXI_ARRAY
indicates undesirable usage of struct to readers.

- Parsing into temporary string_list or oid_array complicates code
by adding more return paths, as these structures needs to be
cleared before returning from function.

- Determining number of hashes by counting separators might cause
maintenance issues, if this function needs to be modified in future
again.

Documentation: use proper wording for ref format strings

Various commands list refs and allow to use a format string for the
output that interpolates from the ref as well as the object it points
at (for-each-ref; branch and tag in list mode).

Currently, the documentation talks about interpolating from the object.
This is confusing because a ref points to an object but not vice versa,
so the object cannot possible know %(refname), for example. Thus, this is
wrong independent of refs being objects (one day, maybe) or not.

Change the wording to make this clearer (and distinguish it from formats
for the log family).

diff: retire sane_truncate_fn

Long time ago, 23707811 ("diff: do not chomp hunk-header in the
middle of a character", 2008-01-02) introduced sane_truncate_line()
helper function to trim the "function header" line that is shown at
the end of the hunk header line, in order to avoid chomping it in
the middle of a single UTF-8 character. It also added a facility to
define a custom callback function to make it possible to extend it
to non UTF-8 encodings.

During the following 8 1/2 years, nobody found need for this custom
callback facility.

A custom callback function is a wrong design to use here anyway---if
your contents need support for non UTF-8 encoding, you shouldn't
have to write a custom function and recompile Git to plumb it in. A
better approach would be to extend sane_truncate_line() function and
have a new member in emit_callback to conditionally trigger it.

files-backend: cheapen refname_available check when locking refs

When locking references in preparation for updating them, we need to
check that none of the newly added references D/F conflict with
existing references (e.g., we don't allow `refs/foo` to be added if
`refs/foo/bar` already exists, or vice versa).

Prior to 524a9fdb51 (refs_verify_refname_available(): use function in
more places, 2017-04-16), conflicts with existing loose references
were checked by looking directly in the filesystem, and then conflicts
with existing packed references were checked by running
`verify_refname_available_dir()` against the packed-refs cache.

But that commit changed the final check to call
`refs_verify_refname_available()` against the *whole* files ref-store,
including both loose and packed references, with the following
comment:

> This means that those callsites now check for conflicts with all
> references rather than just packed refs, but the performance cost
> shouldn't be significant (and will be regained later).

That comment turned out to be too sanguine. User s@kazlauskas.me
reported that fetches involving a very large number of references in
neighboring directories were slowed down by that change.

The problem is that when fetching, each reference is updated
individually, within its own reference transaction. This is done
because some reference updates might succeed even though others fail.
But every time a reference update transaction is finished,
`clear_loose_ref_cache()` is called. So when it is time to update the
next reference, part of the loose ref cache has to be repopulated for
the `refs_verify_refname_available()` call. If the references are all
in neighboring directories, then the cost of repopulating the
reference cache increases with the number of references, resulting in
O(N²) effort.

The comment above also claims that the performance cost "will be
regained later". The idea was that once the packed-refs were finished
being split out into a separate ref-store, we could limit the
`refs_verify_refname_available()` call to the packed references again.
That is what we do now.

diff: define block by number of alphanumeric chars

The existing behavior of diff --color-moved=zebra does not define the
minimum size of a block at all, instead relying on a heuristic applied
later to filter out sets of adjacent moved lines that are shorter than 3
lines long. This can be confusing, because a block could thus be colored
as moved at the source but not at the destination (or vice versa),
depending on its neighbors.

Instead, teach diff that the minimum size of a block is 20 alphanumeric
characters, the same heuristic used by "git blame". This allows diff to
still exclude uninteresting lines appearing on their own (such as those
solely consisting of one or a few closing braces), as was the intention
of the adjacent-moved-line heuristic.

This requires a change in some tests in that some of their lines are no
longer considered to be part of a block, because they are too short.

t1002: stop using sum(1)René Scharfe Mon, 14 Aug 2017 20:16:34 +0000 (22:16 +0200)

t1002: stop using sum(1)

sum(1) is a command for calculating checksums of the contents of files.
It was part of early editions of Unix ("Research Unix", 1972/1973, [1]).
cksum(1) appeared in 4.4BSD (1993) as a replacement [2], and became part
of POSIX.1-2008 [3]. OpenBSD 5.6 (2014) removed sum(1).

We only use sum(1) in t1002 to check for changes in three files. On
MinGW we use md5sum(1) instead. We could switch to the standard command
cksum(1) for all platforms; MinGW comes with GNU coreutils now, which
provides sum(1), cksum(1) and md5sum(1). Use our standard method for
checking for file changes instead: test_cmp.

It's more convenient because it shows differences nicely, it's faster on
MinGW because we have a special implementation there based only on
shell-internal commands, it's simpler as it allows us to avoid stripping
out unnecessary entries from the checksum file using grep(1), and it's
more consistent with the rest of the test suite.

We already compare changed files with their expected new contents using
diff(1), so we don't need to check with "test_must_fail test_cmp" if
they differ from their original state. A later patch could convert the
direct diff(1) calls to test_cmp as well.

With all sum(1) calls gone, remove the MinGW-specific implementation
from test-lib.sh as well.

stash: prevent warning about null bytes in input

The `no_changes` function calls the `untracked_files` function through
command substitution. `untracked_files` will return null bytes because it
runs ls-files with the '-z' option.

Bash since version 4.4 warns about these null bytes. As they are not
required for the test that is being done, make sure `untracked_files`
does not output null bytes when not required.

This is achieved by adding a parameter to the `untracked_files` function to
specify wither `-z` should be passed to ls-files or not.

This warning is triggered when running git stash save -u resulting in
two warnings:

rebase: turn on progress option by default for format-patch

Pass the "--progress" option to format-patch when the standard error
stream is connected to the terminal and "--quiet" is not given.

format-patch: have progress option while generating... Kevin Willford Thu, 10 Aug 2017 18:32:55 +0000 (14:32 -0400)

format-patch: have progress option while generating patches

When generating patches for the rebase command, if the user does
not realize the branch they are rebasing onto is thousands of
commits different, there is no progress indication after initial
rewinding message.

The progress meter as presented in this patch assumes the thousands of
patches to have a fine granularity as well as assuming to require all
the same amount of work/time for each, such that a steady progress bar
is achieved.

We do not want to estimate the time for each patch based e.g.
on their size or number of touched files (or parents) as that is too
expensive for just a progress meter.

This patch allows a progress option to be passed to format-patch
so that the user can be informed the progress of generating the
patch. This option is then used by the rebase command when
calling format-patch.

tree-walk: convert fill_tree_descriptor() to object_idRené Scharfe Sat, 12 Aug 2017 08:32:59 +0000 (10:32 +0200)

tree-walk: convert fill_tree_descriptor() to object_id

All callers of fill_tree_descriptor() have been converted to object_id
already, so convert that function as well. As a nice side-effect we get
rid of NULL checks in tree-diff.c, as fill_tree_descriptor() already
does them for us.

diff: avoid redundantly clearing a flag

No code in diff.c sets DIFF_SYMBOL_MOVED_LINE except in
mark_color_as_moved(), so it is redundant to clear it for the current
line. Therefore, clear it only for previous lines.

This makes a refactoring in a subsequent patch easier.

interpret-trailers: add options for actions

Allow using non-default values for trailers without having to set
them up in .gitconfig first. For example, if you have the following
configuration

trailer.signed-off-by.where = end

you may use "--where before" when a patch author forgets his
Signed-off-by and provides it in a separate email. Likewise for
--if-exists and --if-missing

Reverting to the behavior specified by .gitconfig is done with
--no-where, --no-if-exists and --no-if-missing.

hook: use correct logical variable

Sign-off added should be that of the "committer", not that of the
"commit's author"; that is how the rest of Git adds sign-off using
sequencer.c::append_signoff().

Use the correct logical variable that identifies the committer.

stash: clean untracked files before resetNicolas Morey-Chaisemartin Fri, 11 Aug 2017 17:14:43 +0000 (19:14 +0200)

stash: clean untracked files before reset

If calling git stash -u on a repo that contains a file that is not
ignored any more due to a current modification of the gitignore file,
this file is stashed but not remove from the working tree.
This is due to git-stash first doing a reset --hard which clears the
.gitignore file modification and the call git clean, leaving the file
untouched.
This causes git stash pop to fail due to the file existing.

This patch simply switches the order between cleaning and resetting
and adds a test for this usecase.

sha1_file: remove read_packed_sha1()

Use read_object() in its place instead. This avoids duplication of code.

This makes force_object_loose() slightly slower (because of a redundant
check of loose object storage), but only in the error case.

sha1_file: set whence in storage-specific info fn

Move the setting of oi->whence to sha1_loose_object_info() and
packed_object_info().

This allows sha1_object_info_extended() to not need to know about the
delta base cache. This will be useful during a future refactoring in
which packfile-related functions, including the handling of the delta
base cache, will be moved to a separate file.

Merge branch 'ma/pager-per-subcommand-action'Junio C Hamano Fri, 11 Aug 2017 20:27:07 +0000 (13:27 -0700)

Merge branch 'ma/pager-per-subcommand-action'

The "tag.pager" configuration variable was useless for those who
actually create tag objects, as it interfered with the use of an
editor. A new mechanism has been introduced for commands to enable
pager depending on what operation is being carried out to fix this,
and then "git tag -l" is made to run pager by default.

* ma/pager-per-subcommand-action:
git.c: ignore pager.* when launching builtin as dashed external
tag: change default of `pager.tag` to "on"
tag: respect `pager.tag` in list-mode only
t7006: add tests for how git tag paginates
git.c: provide setup_auto_pager()
git.c: let builtins opt for handling `pager.foo` themselves
builtin.h: take over documentation from api-builtin.txt
