a26345b608 grep: optimize built-in grep by skipping lines that do not hit
The internal "grep" engine we use checks for hits line-by-line, instead of
letting the underlying regexec()/fixmatch() routines scan for the first
match from the rest of the buffer.  This was a major source of overhead
compared to the external grep.

Introduce a "look-ahead" mechanism to find the next line that would
potentially match by using regexec()/fixmatch() in the remainder of the
text to skip unmatching lines, and use it when the query criteria is
simple enough (i.e. punt for an advanced grep boolean expression like
"lines that have both X and Y but not Z" for now) and we are not running
under "-v" (aka "--invert-match") option.

Note that "-L" (aka "--files-without-match") is not a reason to disable
this optimization.  Under the option, we are interested if the file has
any hit at all, and that is what we determine reliably with or without the
optimization.

fbb9971aca grep: -L should show empty files
The -L (--files-without-match) option is supposed to show paths that
produced no matches.  When running the internal grep on work tree files,
however, we had an optimization to just return on zero-sized files,
without doing anything.

This optimization doesn't matter too much in practice (a tracked empty
file must be rare, or there is something wrong with your project); to
produce results consistent with GNU grep, we should stop the optimization
and show empty files as not having the given pattern.

2b77029f4a rebase--interactive: Ignore comments and blank lines in peek_next_command
Previously, blank lines and/or comments within a series of
squash/fixup commands would confuse "git rebase -i" into thinking that
the series was finished.  It would therefore require the user to edit
the commit message for the squash/fixup commits seen so far.  Then,
after continuing, it would ask the user to edit the commit message
again.

Ignore comments and blank lines within a group of squash/fixup
commands, allowing them to be processed in one go.

c5e558a80a Remove empty directories when checking out a commit with fewer submodules
Change the unlink_entry function to use rmdir to remove submodule
directories.  Currently we try to use unlink, which will never succeed.

Of course rmdir will only succeed for empty (i.e. not checked out)
submodule directories.  Behaviour if a submodule is checked out stays
essentially the same: print a warning message and keep the submodule
directory.

91dc602de9 Use $(git rev-parse --show-toplevel) in cd_to_toplevel().
rev-parse --show-toplevel gives the absolute (aka "physical") path of the
toplevel directory and is more portable as 'cd -P' is not supported by all
shell implementations.

This is also closer to what setup_work_tree() does.

27d6b08536 rerere: refactor rerere logic to make it independent from I/O
This splits the handle_file() function into in-core part and I/O
parts of the logic to create the preimage, so that we can compute
the conflict identifier without having to use temporary files.

Earlier, I thought the output from handle_file() should also be
refactored, but it is always about writing preimage (or thisimage)
that is used for later three-way merge, so it is saner to keep it
to always write to FILE *.

2b541bf8be start_command: detect execvp failures early
Previously, failures during execvp could be detected only by
finish_command. However, in some situations it is beneficial for the
parent process to know earlier that the child process will not run.

The idea to use a pipe to signal failures to the parent process and
the test case were lifted from patches by Ilari Liusvaara.

a5487ddf0f start_command: report child process setup errors to the parent's stderr
When the child process's environment is set up in start_command(), error
messages were written to wherever the parent redirected the child's stderr
channel. However, even if the parent redirected the child's stderr, errors
during this setup process, including the exec itself, are usually an
indication of a problem in the parent's environment. Therefore, the error
messages should go to the parent's stderr.

Redirection of the child's error messages is usually only used to redirect
hook error messages during client-server exchanges. In these cases, hook
setup errors could be regarded as information leak.

This patch makes a copy of stderr if necessary and uses a special
die routine that is used for all die() calls in the child that sends the
errors messages to the parent's stderr.

The trace call that reported a failed execvp is removed (because it writes
to stderr) and replaced by die_errno() with special treatment of ENOENT.
The improvement in the error message can be seen with this sequence:

   mkdir .git/hooks/pre-commit
   git commit

Previously, the error message was

   error: cannot run .git/hooks/pre-commit: No such file or directory

and now it is

   fatal: cannot exec '.git/hooks/pre-commit': Permission denied

91c38a2108 ident.c: check explicit identity for name and email separately
bb1ae3f (commit: Show committer if automatic, 2008-05-04) added a logic to
check both name and email were given explicitly by the end user, but it
assumed that fmt_ident() is never called before git_default_user_config()
is called, which was fragile.  The former calls setup_ident() and fills
the "default" name and email, so the check in the config parser would have
mistakenly said both are given even if only user.name was provided.

Make the logic more robust by keeping track of name and email separately.

0b444cdb19 Documentation: spell 'git cmd' without dash throughout
The documentation was quite inconsistent when spelling 'git cmd' if it
only refers to the program, not to some specific invocation syntax:
both 'git-cmd' and 'git cmd' spellings exist.

The current trend goes towards dashless forms, and there is precedent
in 647ac70 (git-svn.txt: stop using dash-form of commands.,
2009-07-07) to actively eliminate the dashed variants.

Replace 'git-cmd' with 'git cmd' throughout, except where git-shell,
git-cvsserver, git-upload-pack, git-receive-pack, and
git-upload-archive are concerned, because those really live in the
$PATH.

message in the remote_status member) if the reported status is 'no

This allows the user to be alerted to more "interesting" ref statuses,

20e8b465a5 refactor ref status logic for pushing
Move the logic that detects up-to-date and non-fast-forward refs to a
new function in remote.[ch], set_ref_status_for_push().

Make transport_push() invoke set_ref_status_for_push() before invoking
the push_refs() implementation. (As a side-effect, the push_refs()
implementation in transport-helper.c now knows of non-fast-forward
pushes.)

Removed logic for detecting up-to-date refs from the push_refs()
implementation in transport-helper.c, as transport_push() has already
done so for it.

Make cmd_send_pack() invoke set_ref_status_for_push() before invoking
send_pack(), as transport_push() can't do it for send_pack() here.

Mark the test on the return status of non-fast-forward push to fail.
Git now exits with success, as transport.c::transport_push() does not
check for refs with status REF_STATUS_REJECT_NONFASTFORWARD nor does it
indicate rejected pushes with its return value.

Mark the test for ref status to succeed. As mentioned earlier, refs
might be marked as non-fast-forwards, triggering the push status
printing mechanism in transport.c.
