interpret-trailers: add an option to show only existing trailers

It can be useful to invoke interpret-trailers for the
primary purpose of parsing existing trailers. But in that
case, we don't want to apply existing ifMissing or ifExists
rules from the config. Let's add a special mode where we
avoid applying those rules. Coupled with --only-trailers,
this gives us a reasonable parsing tool.

interpret-trailers: add an option to show only the trailers

In theory it's easy for any reader who wants to parse
trailers to do so. But there are a lot of subtle corner
cases around what counts as a trailer, when the trailer
block begins and ends, etc. Since interpret-trailers already
has our parsing logic, let's let callers ask it to just
output the trailers.

They still have to parse the "key: value" lines, but at
least they can ignore all of the other corner cases.

stash: prevent warning about null bytes in inputKevin Daudt Mon, 14 Aug 2017 21:43:33 +0000 (23:43 +0200)

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:

git-stash: line 43: warning: command substitution: ignored null byte
in input

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.

No code in diff.c sets DIFF_SYMBOL_MOVED_LINE except in

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.

When unpack_entry() encounters a broken packed object, it returns early.

sha1_file: drop experimental GIT_USE_LOOKUP searchJeff King Wed, 9 Aug 2017 10:14:32 +0000 (06:14 -0400)

sha1_file: drop experimental GIT_USE_LOOKUP search

Long ago in 628522ec14 (sha1-lookup: more memory efficient
search in sorted list of SHA-1, 2007-12-29) we added
sha1_entry_pos(), a binary search that uses the uniform
distribution of sha1s to scale the selection of mid-points.
As this was a performance experiment, we tied it to the
GIT_USE_LOOKUP environment variable and never enabled it by
default.

This code was successful in reducing the number of steps in
each search. But the overhead of the scaling ends up making
it slower when the cache is warm. Here are best-of-five
timings for running rev-list on linux.git, which will have
to look up every object:

$ time git rev-list --objects --all >/dev/null
real 0m35.357s
user 0m35.016s
sys 0m0.340s

$ time GIT_USE_LOOKUP=1 git rev-list --objects --all >/dev/null
real 0m37.364s
user 0m37.045s
sys 0m0.316s

The USE_LOOKUP version might have more benefit on a cold
cache, as the time to fault in each page would dominate. But
that would be for a single lookup. In practice, most
operations tend to look up many objects, and the whole pack
.idx will end up warm.

It's possible that the code could be better optimized to
compete with a naive binary search for the warm-cache case,
and we could have the best of both worlds. But over the
years nobody has done so, and this is largely dead code that
is rarely run outside of the test suite. Let's drop it in
the name of simplicity.

This lets us remove sha1_entry_pos() entirely, as the .idx
lookup code was the only caller. Note that sha1-lookup.c
still contains sha1_pos(), which differs from
sha1_entry_pos() in two ways:

- it has a different interface; it uses a function pointer
to access sha1 entries rather than a size/offset pair
describing the table's memory layout

- it only scales the initial selection of "mi", rather
than each iteration of the search

We can't get rid of this function, as it's called from
several places. It may be that we could replace it with a
simple binary search, but that's out of scope for this patch
(and would need benchmarking).

hashcmp: use memcmp instead of open-coded loopJeff King Wed, 9 Aug 2017 10:16:45 +0000 (06:16 -0400)

hashcmp: use memcmp instead of open-coded loop

In 1a812f3a70 (hashcmp(): inline memcmp() by hand to
optimize, 2011-04-28), it was reported that an open-coded
loop outperformed memcmp() for comparing sha1s.

Discussion[1] a few years later in 2013 showed that this
depends on your libc's version of memcmp(). In particular,
glibc 2.13 optimized their memcmp around 2011. Here are
current timings with glibc 2.24 (best-of-five, on
linux.git):

[before this patch, open-coded]
$ time git rev-list --objects --all
real 0m35.357s
user 0m35.016s
sys 0m0.340s

[after this patch, memcmp]
real 0m32.930s
user 0m32.630s
sys 0m0.300s

Now that we've had 6 years for that version of glibc to
make its way onto people's machines, it's worth revisiting
our benchmarks and switching to memcmp().

It may be that there are other non-glibc systems where
memcmp() isn't as well optimized. But since our single data
point in favor of open-coding was on a now-ancient glibc, we
should probably assume the system memcmp is good unless
proven otherwise. We may end up with a SLOW_MEMCMP Makefile
knob, but we can hold off on that until we actually find
such a system in practice.

sha1_file: avoid comparison if no packed hash matches the first byte

find_pack_entry_one() uses the fan-out table of pack indexes to find out
which entries match the first byte of the searched hash and does a
binary search on this subset of the main index table.

If there are no matching entries then lo and hi will have the same
value. The binary search still starts and compares the hash of the
following entry (which has a non-matching first byte, so won't cause any
trouble), or whatever comes after the sorted list of entries.

The probability of that stray comparison matching by mistake is low, but
let's not take any chances and check when entering the binary search
loop if we're actually done already.

config: make git_{config,parse}_maybe_bool equivalent

Both of these act on a string `value` which they parse as a boolean. The
"parse"-variant was introduced as a replacement for the "config"-variant
which for historical reasons takes an unused argument `name`. That it
was intended as a replacement is not obvious from commit 9a549d43
("config.c: rename git_config_maybe_bool_text and export it as
git_parse_maybe_bool", 2015-08-19), but that is what the background on
the mailing list suggests [1].

However, these two functions do not parse `value` in exactly the same
way. In particular, git_config_maybe_bool accepts integers (0 for false,
non-0 for true). This means there are two slightly different definitions
of "maybe_bool" in the code-base, and that every time a call to
git_config_maybe_bool is changed to use git_parse_maybe_bool, it risks
breaking someone's workflow.

Move the implementation of "config" into "parse" and make the latter a
trivial wrapper.

This also fixes the only user of git_parse_maybe_bool, `git push
--signed=..`.

Commit 9a549d43 ("config.c: rename git_config_maybe_bool_text and export

to be a replacement for git_config_maybe_bool, which could then be
retired. That is not obvious from the commit message, but that is what
the background on the mailing list suggests [1].

However, git_{config,parse}_maybe_bool do not handle all input the same.
Before the rename, that was by design and there is a caller in config.c
which requires git_parse_maybe_bool to behave exactly as it does.

Prepare for the next patch by renaming git_parse_maybe_bool to ..._text
and reimplementing the first one as a simple call to the second one. Let
the existing users in config.c use ..._text, since it does what they
need.

Doc/git-{push,send-pack}: correct --sign= to --signed=

Since we're about to touch the behavior of --signed=, do this as a
preparatory step.

The documentation mentions --sign=, and it works. But that's just
because it's an unambiguous abbreviation of --signed, which is how it is
actually implemented. This was added in commit 30261094 ("push: support
signing pushes iff the server supports it", 2015-08-19). Back when that
series was developed [1] [2], there were suggestions about both --sign=
and --signed=. The final implementation settled on --signed=, but some
of the documentation and commit messages ended up using --sign=.

The option is referred to as --signed= in Documentation/config.txt
(under push.gpgSign).

One could argue that we have promised --sign for two years now, so we
should implement it as an alias for --signed. (Then we might also
deprecate the latter, something which was considered already then.) That
would be a slightly more intrusive change.

This minor issue would only be a problem once we want to implement some
other option --signfoo, but the earlier we do this step, the better.

submodule: remove gitmodules_config

Now that the submodule-config subsystem can lazily read the gitmodules
file we no longer need to explicitly pre-read the gitmodules by calling
'gitmodules_config()' so let's remove it.

unpack-trees: improve loading of .gitmodules

When recursing submodules 'check_updates()' needs to have strict control
over the submodule-config subsystem to ensure that the gitmodules file
has been read before checking cache entries which are marked for
removal as well ensuring the proper gitmodules file is read before
updating cache entries.

Because of this let's not rely on callers of 'check_updates()' to read
the gitmodules file before calling 'check_updates()' and handle the
reading explicitly.

submodule-config: lazy-load a repository's .gitmodules... Brandon Williams Thu, 3 Aug 2017 18:19:58 +0000 (11:19 -0700)

submodule-config: lazy-load a repository's .gitmodules file

In order to use the submodule-config subsystem, callers first need to
initialize it by calling 'repo_read_gitmodules()' or
'gitmodules_config()' (which just redirects to
'repo_read_gitmodules()'). There are a couple of callers who need to
load an explicit revision of the repository's .gitmodules file (grep) or
need to modify the .gitmodules file so they would need to load it before
modify the file (checkout), but the majority of callers are simply
reading the .gitmodules file present in the working tree. For the
common case it would be nice to avoid the boilerplate of initializing
the submodule-config system before using it, so instead let's perform
lazy-loading of the submodule-config system.

Remove the calls to reading the gitmodules file from ls-files to show
that lazy-loading the .gitmodules file works.

diff: stop allowing diff to have submodules configured... Brandon Williams Thu, 3 Aug 2017 18:19:55 +0000 (11:19 -0700)

diff: stop allowing diff to have submodules configured in .git/config

Traditionally a submodule is comprised of a gitlink as well as a
corresponding entry in the .gitmodules file. Diff doesn't follow this
paradigm as its config callback routine falls back to populating the
submodule-config if a config entry starts with 'submodule.'.

Remove this behavior in order to be consistent with how the
submodule-config is populated, via calling 'gitmodules_config()' or
'repo_read_gitmodules()'.

submodule: remove submodule_config callback routine

Remove the last remaining caller of 'submodule_config()' as well as the
function itself.

With 'submodule_config()' being removed the submodule-config API can be
a little simpler as callers don't need to worry about whether or not
they need to overlay the repository's config on top of the
submodule-config. This also makes it more difficult to accidentally
add non-submodule specific configuration to the .gitmodules file.

unpack-trees: don't respect submodule.update

The 'submodule.update' config was historically used and respected by the
'submodule update' command because update handled a variety of different
ways it updated a submodule. As we begin teaching other commands about
submodules it makes more sense for the different settings of
'submodule.update' to be handled by the individual commands themselves
(checkout, rebase, merge, etc) so it shouldn't be respected by the
native checkout command.

Also remove the overlaying of the repository's config (via using
'submodule_config()') from the commands which use the unpack-trees
logic (checkout, read-tree, reset).

git.c: ignore pager.* when launching builtin as dashed... Martin Ågren Wed, 2 Aug 2017 19:40:55 +0000 (21:40 +0200)

git.c: ignore pager.* when launching builtin as dashed external

When running, e.g., `git -c alias.bar=foo bar`, we expand the alias and
execute `git-foo` as a dashed external. This is true even if git foo is
a builtin. That is on purpose, and is motivated in a comment which was
added in commit 441981bc ("git: simplify environment save/restore
logic", 2016-01-26).

Shortly before we launch a dashed external, and unless we have already
found out whether we should use a pager, we check `pager.foo`. This was
added in commit 92058e4d ("support pager.* for external commands",
2011-08-18). If the dashed external is a builtin, this does not match
that commit's intention and is arguably wrong, since it would be cleaner
if we let the "dashed external builtin" handle `pager.foo`.

This has not mattered in practice, but a recent patch taught `git-tag`
to ignore `pager.tag` under certain circumstances. But, when started
using an alias, it doesn't get the chance to do so, as outlined above.
That recent patch added a test to document this breakage.

Do not check `pager.foo` before launching a builtin as a dashed
external, i.e., if we recognize the name of the external as a builtin.
Change the test to use `test_expect_success`.

tag: change default of `pager.tag` to "on"Martin Ågren Wed, 2 Aug 2017 19:40:54 +0000 (21:40 +0200)

tag: change default of `pager.tag` to "on"

The previous patch taught `git tag` to only respect `pager.tag` in
list-mode. That patch left the default value of `pager.tag` at "off".

After that patch, it makes sense to let the default value be "on"
instead, since it will help with listing many tags, but will not hurt
users of `git tag -a` as it would have before. Make that change. Update
documentation and tests.

tag: respect `pager.tag` in list-mode onlyMartin Ågren Wed, 2 Aug 2017 19:40:53 +0000 (21:40 +0200)

tag: respect `pager.tag` in list-mode only

Using, e.g., `git -c pager.tag tag -a new-tag` results in errors such as
"Vim: Warning: Output is not to a terminal" and a garbled terminal.
Someone who makes use of both `git tag -a` and `git tag -l` will
probably not set `pager.tag`, so that `git tag -a` will actually work,
at the cost of not paging output of `git tag -l`.

Use the mechanisms introduced in two earlier patches to ignore
`pager.tag` in git.c and let the `git tag` builtin handle it on its own.
Only respect `pager.tag` when running in list-mode.

There is a window between where the pager is started before and after
this patch. This means that early errors can behave slightly different
before and after this patch. Since operation-parsing has to happen
inside this window, this can be seen with `git -c pager.tag="echo pager
is used" tag -l --unknown-option`. This change in paging-behavior should
be acceptable since it only affects erroneous usages.

Update the documentation and update tests.

If an alias is used to run `git tag -a`, then `pager.tag` will still be
respected. Document this known breakage. It will be fixed in a later
commit. Add a similar test for `-l`, which works.
