52bae62f78 Merge branch 'tg/grep-no-index-fallback'
"git grep" by default does not fall back to its "--no-index"
behaviour outside a directory under Git's control (otherwise the
user may by mistake end up running a huge recursive search); with a
new configuration (set in $HOME/.gitconfig--by definition this
cannot be set in the config file per project), this safety can be
disabled.

7a63c9e3da Merge branch 'js/fopen-harder'
Some codepaths used fopen(3) when opening a fixed path in $GIT_DIR
(e.g. COMMIT_EDITMSG) that is meant to be left after the command is
done.  This however did not work well if the repository is set to
be shared with core.sharedRepository and the umask of the previous
user is tighter.  They have been made to work better by calling
unlink(2) and retrying after fopen(3) fails with EPERM.

Some "git notes" operations, e.g. "git log --notes=<note>", should

99c08d4eb2 ls-remote: add support for showing symrefs
Sometimes it's useful to know the main branch of a git repository
without actually downloading the repository.  This can be done by
looking at the symrefs stored in the remote repository.  Currently git
doesn't provide a simple way to show the symrefs stored on the remote
repository, even though the information is available.  Add a --symref
command line argument to the ls-remote command, which shows the symrefs
in the remote repository.

While there, replace a literal tab in the format string with \t to make
it more obvious to the reader.

d6b16ce914 shortlog: don't warn on empty author
Git tries to avoid creating a commit with an empty author
name or email. However, commits created by older, less
strict versions of git may still be in the history.  There's
not much point in issuing a warning to stderr for an empty
author. The user can't do anything about it now, and we are
better off to simply include it in the shortlog output as an
empty name/email, and let the caller process it however they
see fit.

Older versions of shortlog differentiated between "author
header not present" (which complained) and "author
name/email are blank" (which included the empty ident in the
output).  But since switching to format_commit_message, we
complain to stderr about either case (linux.git has a blank
author deep in its history which triggers this).

We could try to restore the older behavior (complaining only
about the missing header), but in retrospect, there's not
much point in differentiating these cases. A missing
author header is bogus, but as for the "blank" case, the
only useful behavior is to add it to the "empty name"
collection.

9b21a34a96 shortlog: optimize out useless string list
If we are in "--summary" mode, then we do not care about the
actual list of subject onelines associated with each author.
We care only about the number. So rather than store a
string-list for each author full of "<none>", let's just
keep a count.

This drops my best-of-five for "git shortlog -ns HEAD" on
linux.git from:

  real    0m5.194s
  user    0m5.028s
  sys     0m0.168s

to:

  real    0m5.057s
  user    0m4.916s
  sys     0m0.144s

That's about 2.5%.

ed7eba9022 shortlog: optimize out useless "<none>" normalization
If we are in --summary mode, we will always pass <none> to
insert_one_record, which will then do some normalization
(e.g., cutting out "[PATCH]"). There's no point in doing so
if we aren't going to use the result anyway.

This drops my best-of-five for "git shortlog -ns HEAD" on
linux.git from:

  real    0m5.257s
  user    0m5.104s
  sys     0m0.156s

to:

  real    0m5.194s
  user    0m5.028s
  sys     0m0.168s

That's only 1%, but arguably the result is clearer to read,
as we're able to group our variable declarations inside the
conditional block. It also opens up further optimization
possibilities for future patches.

4e1d1a2eea shortlog: optimize "--summary" mode
If the user asked us only to show counts for each author,
rather than the individual summary lines, then there is no
point in us generating the summaries only to throw them
away. With this patch, I measured the following speedup for
"git shortlog -ns HEAD" on linux.git (best-of-five):

  [before]
  real    0m5.644s
  user    0m5.472s
  sys     0m0.176s

  [after]
  real    0m5.257s
  user    0m5.104s
  sys     0m0.156s

That's only ~7%, but it's so easy to do, there's no good
reason not to. We don't have to touch any downstream code,
since we already fill in the magic string "<none>" to handle
commits without a message.

2db6b83d18 shortlog: replace hand-parsing of author with pretty-printer
When gathering the author and oneline subject for each
commit, we hand-parse the commit headers to find the
"author" line, and then continue past to the blank line at
the end of the header.

We can replace this tricky hand-parsing by simply asking the
pretty-printer for the relevant items. This also decouples
the author and oneline parsing, opening up some new
optimizations in further commits.

One reason to avoid the pretty-printer is that it might be
less efficient than hand-parsing. However, I measured no
slowdown at all running "git shortlog -ns HEAD" on
linux.git.

As a bonus, we also fix a memory leak in the (uncommon) case
that the author field is blank.

50250491bd shortlog: use strbufs to read from stdin
We currently use fixed-size buffers with fgets(), which
could lead to incorrect results in the unlikely event that a
line had something like "Author:" at exactly its 1024th
character.

But it's easy to convert this to a strbuf, and because we
can reuse the same buffer through the loop, we don't even
pay the extra allocation cost.

5c3894c39d shortlog: match both "Author:" and "author" on stdin
The original git-shortlog could read both the normal "git
log" output as well as "git log --format=raw". However, when
it was converted to C by b8ec592 (Build in shortlog,
2006-10-22), the trailing colon became mandatory, and we no
longer matched the raw output.

Given the amount of intervening time without any bug
reports, it's probable that nobody cares. But it's
relatively easy to fix, and the end result is hopefully more
readable than the original.

Note that this no longer matches "author: ", which we did
before, but that has never been a format generated by git.

a7630bd427 ls-files: add eol diagnostics
When working in a cross-platform environment, a user may want to
check if text files are stored normalized in the repository and
if .gitattributes are set appropriately.

Make it possible to let Git show the line endings in the index and
in the working tree and the effective text/eol attributes.

The end of line ("eolinfo") are shown like this:

    "-text"        binary (or with bare CR) file
    "none"         text file without any EOL
    "lf"           text file with LF
    "crlf"         text file with CRLF
    "mixed"        text file with mixed line endings.

The effective text/eol attribute is one of these:

    "", "-text", "text", "text=auto", "text eol=lf", "text eol=crlf"

git ls-files --eol gives an output like this:

    i/none   w/none   attr/text=auto      t/t5100/empty
    i/-text  w/-text  attr/-text          t/test-binary-2.png
    i/lf     w/lf     attr/text eol=lf    t/t5100/rfc2047-info-0007
    i/lf     w/crlf   attr/text eol=crlf  doit.bat
    i/mixed  w/mixed  attr/               locale/XX.po

to show what eol convention is used in the data in the index ('i'),
and in the working tree ('w'), and what attribute is in effect,
for each path that is shown.

Add test cases in t0027.

b3715b7522 notes: allow merging from arbitrary references
Create a new expansion function, expand_loose_notes_ref which will first
check whether the ref can be found using get_sha1. If it can't be found
then it will fallback to using expand_notes_ref. The content of the
strbuf will not be changed if the notes ref can be located using
get_sha1. Otherwise, it may be updated as done by expand_notes_ref.

Since we now support merging from non-notes refs, remove the test case
associated with that behavior. Add a test case for merging from a
non-notes ref.

8f309aeb82 strbuf: introduce strbuf_getline_{lf,nul}()
The strbuf_getline() interface allows a byte other than LF or NUL as
the line terminator, but this is only because I wrote these
codepaths anticipating that there might be a value other than NUL
and LF that could be useful when I introduced line_termination long
time ago.  No useful caller that uses other value has emerged.

By now, it is clear that the interface is overly broad without a
good reason.  Many codepaths have hardcoded preference to read
either LF terminated or NUL terminated records from their input, and
then call strbuf_getline() with LF or NUL as the third parameter.

This step introduces two thin wrappers around strbuf_getline(),
namely, strbuf_getline_lf() and strbuf_getline_nul(), and
mechanically rewrites these call sites to call either one of
them.  The changes contained in this patch are:

 * introduction of these two functions in strbuf.[ch]

 * mechanical conversion of all callers to strbuf_getline() with
   either '\n' or '\0' as the third parameter to instead call the
   respective thin wrapper.

After this step, output from "git grep 'strbuf_getline('" would
become a lot smaller.  An interim goal of this series is to make
this an empty set, so that we can have strbuf_getline_crlf() take
over the shorter name strbuf_getline().

c8aa9fdf5d strbuf: make strbuf_getline_crlf() global
Often we read "text" files that are supplied by the end user
(e.g. commit log message that was edited with $GIT_EDITOR upon 'git
commit -e'), and in some environments lines in a text file are
terminated with CRLF.  Existing strbuf_getline() knows to read a
single line and then strip the terminating byte from the result, but
it is handy to have a version that is more tailored for a "text"
input that takes both '\n' and '\r\n' as line terminator (aka
<newline> in POSIX lingo) and returns the body of the line after
stripping <newline>.

Recently reimplemented "git am" uses such a function implemented
privately; move it to strbuf.[ch] and make it available for others.

Note that we do not blindly replace calls to strbuf_getline() that
uses LF as the line terminator with calls to strbuf_getline_crlf()
and this is very much deliberate.  Some callers may want to treat an
incoming line that ends with CR (and terminated with LF) to have a
payload that includes the final CR, and such a blind replacement
will result in misconversion when done without code audit.

The way builtin pull works, this change also supports the value
'interactive' for the 'branch.<name>.rebase' config variable, which
is a neat thing because users can now configure given branches for
interactively-rebasing pulls without having to type out the complete
`--rebase=interactive` option every time they pull.

bc6bf2d764 format-patch: introduce format.outputDirectory configuration
We can pass -o/--output-directory to the format-patch command to store
patches in some place other than the working directory. This patch
introduces format.outputDirectory configuration option for same
purpose.

The case of usage of this configuration option can be convenience
to not pass every time -o/--output-directory if an user has pattern
to store all patches in the /patches directory for example.

The format.outputDirectory has lower priority than command line
option, so if user will set format.outputDirectory and pass the
command line option, a result will be stored in a directory that
passed to command line option.

ee76f92fe8 notes: allow treeish expressions as notes ref
init_notes() is the main point of entry to the notes API. It ensures
that the input can be used as ref, because it needs a ref to update to
store notes tree after modifying it.

There however are many use cases where notes tree is only read, e.g.
"git log --notes=...".  Any notes-shaped treeish could be used for such
purpose, but it is not allowed due to existing restriction.

Allow treeish expressions to be used in the case the notes tree is going
to be used without write "permissions".  Add a flag to distinguish
whether the notes tree is intended to be used read-only, or will be
updated.

With this change, operations that use notes read-only can be fed any
notes-shaped tree-ish can be used, e.g. git log --notes=notes@{1}.

ea56518dfe Handle more file writes correctly in shared repos
In shared repositories, we have to be careful when writing files whose
permissions do not allow users other than the owner to write them.

In particular, we force the marks file of fast-export and the FETCH_HEAD
when fetching to be rewritten from scratch.

This commit does not touch other calls to fopen() that want to
write files:

 - commands that write to working tree files (core.sharedRepository
   does not affect permission bits of working tree files),
   e.g. .rej file created by "apply --reject", result of applying a
   previous conflict resolution by "rerere", "git merge-file".

 - git am, when splitting mails (git-am correctly cleans up its directory
   after finishing, so there is no need to share those files between users)

 - git submodule clone, when writing the .git file, because the file
   will not be overwritten

 - git_terminal_prompt() in compat/terminal.c, because it is not writing to
   a file at all

 - git diff --output, because the output file is clearly not intended to be
   shared between the users of the current repository

 - git fast-import, when writing a crash report, because the reports' file
   names are unique due to an embedded process ID

 - mailinfo() in mailinfo.c, because the output is clearly not intended to
   be shared between the users of the current repository

 - check_or_regenerate_marks() in remote-testsvn.c, because this is only
   used for Git's internal testing

 - git fsck, when writing lost&found blobs (this should probably be
   changed, but left as a low-hanging fruit for future contributors).

Note that this patch does not touch callers of write_file() and
write_file_gently(), which would benefit from the same scrutiny as
to usage in shared repositories.  Most notable users are branch,
daemon, submodule & worktree, and a worrisome call in transport.c
when updating one ref (which ignores the shared flag).

9a93c6686f avoid shifting signed integers 31 bits
We sometimes use 32-bit unsigned integers as bit-fields.
It's fine to access the MSB, because it's unsigned. However,
doing so as "1 << 31" is wrong, because the constant "1" is
a signed int, and we shift into the sign bit, causing
undefined behavior.

We can fix this by using "1U" as the constant.

7cb5f7c44d blame: fix object casting regression
Commit 1b0d400 refactored the prepare_final() function so
that it could be reused in multiple places. Originally, the
loop had two outputs: a commit to stuff into sb->final, and
the name of the commit from the rev->pending array.

After the refactor, that loop is put in its own function
with a single return value: the object_array_entry from the
rev->pending array. This contains both the name and the object,
but with one important difference: the object is the
_original_ object found by the revision parser, not the
dereferenced commit. If one feeds a tag to "git blame", we
end up casting the tag object to a "struct commit", which
causes a segfault.

Instead, let's return the commit (properly casted) directly
from the function, and take the "name" as an optional
out-parameter. This does the right thing, and actually
simplifies the callers, who no longer need to cast or
dereference the object_array_entry themselves.

The --recurse-submodules command line parameter has existed for some
time but it has no config file equivalent.

Following the style of the corresponding parameter for git fetch, let's
invent push.recurseSubmodules to provide a default for this
parameter. This also requires the addition of --recurse-submodules=no to
allow the configuration to be overridden on the command line when
required.

The most straightforward way to implement this appears to be to make
push use code in submodule-config in a similar way to fetch.

Having a leftover .idx file without corresponding .pack file in
the repository hurts performance; "git gc" learned to prune them.

* dk/gc-idx-wo-pack:
  gc: remove garbage .idx files from pack dir
  t5304: test cleaning pack garbage
  prepare_packed_git(): refactor garbage reporting in pack directory

eb33876c26 initdb: make safe_create_dir public
Soon we will want to create initdb functions for ref backends, and
code from initdb that calls this function needs to move into the files
backend. So this function needs to be public.

af65f68cdf allow hooks to ignore their standard input stream
Since ec7dbd145 (receive-pack: allow hooks to ignore its
standard input stream) the pre-receive and post-receive
hooks ignore SIGPIPE. Do the same for the remaining hooks
pre-push and post-rewrite, which read from standard input.
The same arguments for ignoring SIGPIPE apply.

Include test by Jeff King which checks that SIGPIPE does not
cause pre-push hook failure. With the use of git update-ref
--stdin it is fast enough to be enabled by default.

usual "--[no-]progress".

78a766ab6e hideRefs: add support for matching full refs
In addition to matching stripped refs, one can now add hideRefs
patterns that the full (unstripped) ref is matched against. To
distinguish between stripped and full matches, those new patterns
must be prefixed with a circumflex (^).

This commit also removes support for the undocumented and unintended
hideRefs settings ".have" (suppressing all "have" lines) and
"capabilities^{}" (suppressing the capabilities line).
