"git config section.var value" to set a value in per-repository
configuration file failed when it was run outside any repository,
but didn't say the reason correctly.

It is a pilot error to call `git config section.key value` outside of
any Git worktree. The message
error: could not lock config file .git/config: No such file or
directory
is not very helpful in that situation, though. Let's print a helpful
message instead.

Handling of errors while writing into our internal asynchronous
process has been made more robust, which reduces flakiness in our
tests.
* jk/epipe-in-async:
t5504: handle expected output from SIGPIPE death

Commit 8bf4bec (add "ok=sigpipe" to test_must_fail and use
it to fix flaky tests, 2015-11-27) taught t5504 to handle
"git push" racily exiting with SIGPIPE rather than failing.
However, one of the tests checks the output of the command,
as well. In the SIGPIPE case, we will not have produced any
output. If we want the test to be truly non-flaky, we have
to accept either output.

If a command is marked as test_must_fail but dies with a
signal, we consider that a problem and report the error to
stderr. However, we don't say _which_ signal; knowing that
can make debugging easier. Let's share as much as we know.

If the other side feeds us a bogus pack, index-pack (or
unpack-objects) may die early, before consuming all of its
input. As a result, the sideband demuxer may get SIGPIPE
(racily, depending on whether our data made it into the pipe
buffer or not). If this happens and we are compiled with
pthread support, it will take down the main thread, too.
This isn't the end of the world, as the main process will
just die() anyway when it sees index-pack failed. But it
does mean we don't get a chance to say "fatal: index-pack
failed" or similar. And it also means that we racily fail
t5504, as we sometimes die() and sometimes are killed by
SIGPIPE.
So let's ignore SIGPIPE while demuxing the sideband. We are
already careful to check the return value of write(), so we
won't waste time writing to a broken pipe. The caller will
notice the error return from the async thread, though in
practice we don't even get that far, as we die() as soon as
we see that index-pack failed.
The non-sideband case is already fine; we let index-pack
read straight from the socket, so there is no SIGPIPE at
all. Technically the non-threaded async case is also OK
without this (the forked async process gets SIGPIPE), but
it's not worth distinguishing from the threaded case here.

When write_or_die() sees EPIPE, it treats it specially by
converting it into a SIGPIPE death. We obviously cannot
ignore it, as the write has failed and the caller expects us
to die. But likewise, we cannot just call die(), because
printing any message at all would be a nuisance during
normal operations.
However, this is a problem if write_or_die() is called from
a thread. Our raised signal ends up killing the whole
process, when logically we just need to kill the thread
(after all, if we are ignoring SIGPIPE, there is good reason
to think that the main thread is expecting to handle it).
Inside an async thread, the die() code already does the
right thing, because we use our custom die_async() routine,
which calls pthread_join(). So ideally we would piggy-back
on that, and simply call:
die_quietly_with_code(141);
or similar. But refactoring the die code to do this is
surprisingly non-trivial. The die_routines themselves handle
both printing and the decision of the exit code. Every one
of them would have to be modified to take new parameters for
the code, and to tell us to be quiet.
Instead, we can just teach write_or_die() to check for the
async case and handle it specially. We do have to build an
interface to abstract the async exit, but it's simple and
self-contained. If we had many call-sites that wanted to do
this die_quietly_with_code(), this approach wouldn't scale
as well, but we don't. This is the only place where do this
weird exit trick.

Across the transition at around Git version 2.0, the user used to
get a pretty loud warning when running "git push" without setting
push.default configuration variable. We no longer warn, given that
the transition is over long time ago.

The warning was important before the 2.0 transition, and remained
important for a while after, so that new users get push.default
explicitly in their configuration and do not experience inconsistent
behavior if they ever used an older version of Git.
The warning has been there since version 1.8.0 (Oct 2012), hence we can
expect the vast majority of current Git users to have been exposed to
it, and most of them have already set push.default explicitly. The
switch from 'matching' to 'simple' was planned for 2.0 (May 2014), but
actually happened only for 2.3 (Feb 2015).
Today, the warning is mostly seen by beginners, who have not set their
push.default configuration (yet). For many of them, the warning is
confusing because it talks about concepts that they have not learned and
asks them a choice that they are not able to make yet. See for example
http://stackoverflow.com/questions/13148066/warning-push-default-is-unset-its-implicit-value-is-changing-in-git-2-0
(1260 votes for the question, 1824 for the answer as of writing)
Remove the warning completely to avoid disturbing beginners. People who
still occasionally use an older version of Git will be exposed to the
warning through this old version.
Eventually, versions of Git without the warning will be deployed enough
and tutorials will not need to advise setting push.default anymore.

Make the find-renames option follow the behaviour in git-diff, where it
resets the threshold when none is given. So, for instance,
"--find-renames=25 --find-renames" should result in the default
threshold (50%) instead of 25%.

When "git submodule update" did not result in fetching the commit
object in the submodule that is referenced by the superproject, the
command learned to retry another fetch, specifically asking for
that commit that may not be connected to the refs it usually
fetches.

submodule: try harder to fetch needed sha1 by direct fetching sha1

When reviewing a change that also updates a submodule in Gerrit, a
common review practice is to download and cherry-pick the patch
locally to test it. However when testing it locally, the 'git
submodule update' may fail fetching the correct submodule sha1 as
the corresponding commit in the submodule is not yet part of the
project history, but also just a proposed change.
If $sha1 was not part of the default fetch, we try to fetch the $sha1
directly. Some servers however do not support direct fetch by sha1,
which leads git-fetch to fail quickly. We can fail ourselves here as
the still missing sha1 would lead to a failure later in the checkout
stage anyway, so failing here is as good as we can get.

Refactor the determination and usage of crlf_action.
Today, when no "crlf" attribute are set on a file, crlf_action is set to
CRLF_GUESS. Use CRLF_UNDEFINED instead, and search for "text" or "eol" as
before.
After searching for line ending attributes, save the value in
struct conv_attrs.crlf_action attr_action,
so that get_convert_attr_ascii() is able report the attributes.
Replace the old CRLF_GUESS usage:
CRLF_GUESS && core.autocrlf=true -> CRLF_AUTO_CRLF
CRLF_GUESS && core.autocrlf=false -> CRLF_BINARY
CRLF_GUESS && core.autocrlf=input -> CRLF_AUTO_INPUT
Save the action in conv_attrs.crlf_action (as before) and change
all callers.
Make more clear, what is what, by defining:
- CRLF_UNDEFINED : No attributes set. Temparally used, until core.autocrlf
and core.eol is evaluated and one of CRLF_BINARY,
CRLF_AUTO_INPUT or CRLF_AUTO_CRLF is selected
- CRLF_BINARY : No processing of line endings.
- CRLF_TEXT : attribute "text" is set, line endings are processed.
- CRLF_TEXT_INPUT: attribute "input" or "eol=lf" is set. This implies text.
- CRLF_TEXT_CRLF : attribute "eol=crlf" is set. This implies text.
- CRLF_AUTO : attribute "auto" is set.
- CRLF_AUTO_INPUT: core.autocrlf=input (no attributes)
- CRLF_AUTO_CRLF : core.autocrlf=true (no attributes)

files given to test_cmp; we compare expect and actual to show how

The default behavior is well documented already in git-config(1), but
git-push(1) itself did not mention it at all. For users willing to learn
how "git push" works but not how to configure it, this makes the
documentation cumbersome to read.
Make the git-push(1) page self-contained by adding a short summary of
what 'push.default=simple' does, early in the page.

The "credential-cache" daemon process used to run in whatever
directory it happened to start in, but this made umount(2)ing the
filesystem that houses the repository harder; now the process
chdir()s to the directory that house its own socket on startup.
* jg/credential-cache-chdir-to-sockdir:
credential-cache--daemon: change to the socket dir on startup
credential-cache--daemon: disallow relative socket path
credential-cache--daemon: refactor check_socket_directory

Changing to the socket path stops the daemon holding open
the directory the user was in when it was started,
preventing umount from working. We're already holding open a
socket in that directory, so there's no downside.

Relative socket paths are dangerous since the user cannot generally
control when the daemon starts (initially, after a timeout, kill or
crash). Since the daemon creates but does not delete the socket
directory, this could lead to spurious directory creation relative
to the users cwd.

This function does an early return, and therefore has to
repeat its cleanup. We can stick the later bit of the
function into an "else" and avoid duplicating the shared
part (which will get bigger in a future patch).
Let's also rename the function to init_socket_directory. It
not only checks the directory but also creates it. Saying
"init" is more accurate.

Rename git_config_set_or_die functions to git_config_set, leading
to the new default behavior of dying whenever a configuration
error occurs.
By now all callers that shall die on error have been transitioned
to the _or_die variants, thus making this patch a simple rename
of the functions.

The desired default behavior for `git_config_set` is to die
whenever an error occurs. Dying is the default for a lot of
internal functions when failures occur and is in this case the
right thing to do for most callers as otherwise we might run into
inconsistent repositories without noticing.
As some code may rely on the actual return values for
`git_config_set` we still require the ability to invoke these
functions without aborting. Rename the existing `git_config_set`
functions to `git_config_set_gently` to keep them available for
those callers.

When calling `git_config_set` to set 'core.precomposeunicode' we
ignore the return value of the function, which may indicate that
we were unable to write the value back to disk. As the function
is only called by init-db we can and should die when an error
occurs.

When we start picking a range of revisions we save the replay
options that are required to restore state when interrupting and
later continuing picking the revisions. However, we do not check
the return values of the `git_config_set` functions, which may
lead us to store incomplete information. As this may lead us to
fail when trying to continue the sequence the error can be fatal.
Fix this by dying immediately when we are unable to write back
any replay option.

When we add or set new branches (e.g. by `git remote add -f` or
`git remote set-branches`) we do not check for error codes when
writing the branches to the configuration file. When persisting
the configuration failed we are left with a remote that has none
or not all of the branches that should have been set without
notifying the user.
Fix this issue by dying early on configuration error.
