55a5c8d72b commit.c: check for lock error and return early
Move the check for the lock failure to happen immediately after
lock_any_ref_for_update().  Previously the lock and the
check-if-lock-failed was separated by a handful of string
manipulation statements.

Moving the check to occur immediately after the failed lock makes
the code slightly easier to read and makes it follow the pattern of

 try-to-take-a-lock();
 if (check-if-lock-failed) {
    error();
 }

651ab9f553 sequencer.c: check for lock failure and bail early in fast_forward_to
Change fast_forward_to() to check if locking the ref failed, print a
nice error message and bail out early.

The old code did not check if ref_lock was NULL and relied on the
fact that the write_ref_sha1() would safely detect this condition
and set the return variable ret to indicate an error.

While that is safe, it makes the code harder to read for two reasons:

 * Inconsistency.  Almost all other places we do check the lock for
   NULL explicitly, so the naive reader is confused "why don't we
   check here?"

 * And relying on write_ref_sha1() to detect and return an error for
   when a previous lock_any_ref_for_update() failed feels obfuscated.

This change should not change any functionality or logic aside from
adding an extra error message when this condition is triggered
(write_ref_sha1() returns an error silently for this condition).

bd368a9baf t9362-mw-to-git-utf8.sh: use the $( ... ) construct for command substitution
The Git CodingGuidelines prefer the $(...) construct for command
substitution instead of using the backquotes `...`.

The backquoted form is the traditional method for command
substitution, and is supported by POSIX.  However, all but the
simplest uses become complicated quickly.  In particular, embedded
command substitutions and/or the use of double quotes require
careful escaping with the backslash character.

47fbfded53 i18n: only extract comments marked with "TRANSLATORS:"
When extract l10n messages, we use "--add-comments" option to keep
comments right above the l10n messages for references.  But sometimes
irrelevant comments are also extracted.  For example in the following
code block, the comment in line 2 will be extracted as comment for the
l10n message in line 3, but obviously it's wrong.

        { OPTION_CALLBACK, 0, "ignore-removal", &addremove_explicit,
          NULL /* takes no arguments */,
          N_("ignore paths removed in the working tree (same as
          --no-all)"),
          PARSE_OPT_NOARG, ignore_removal_cb },

Since almost all comments for l10n translators are marked with the same
prefix (tag): "TRANSLATORS:", it's safe to only extract comments with
this special tag.  I.E. it's better to call xgettext as:

        xgettext --add-comments=TRANSLATORS: ...

Also tweaks the multi-line comment in "init-db.c", to make it start with
the proper tag, not "* TRANSLATORS:" (which has a star before the tag).

8cd65967fe Revert "rebase: fix run_specific_rebase's use of "return" on FreeBSD"
This reverts commit 99855ddf4b.

The workaround 99855ddf introduced to deal with problematic
"return" statements in scripts run by "dot" commands located
inside functions only handles one part of the problem.  The
issue has now been addressed by not using "return" statements
in this way in the git-rebase--*.sh scripts.

This workaround is therefore no longer necessary, so clean
up the code by reverting it.

9f50d32b9c rebase: avoid non-function use of "return" on FreeBSD
Since a1549e10, 15d4bf2e and 01a1e646 (first appearing in v1.8.4)
the git-rebase--*.sh scripts have used a "return" to stop execution
of the dot-sourced file and return to the "dot" command that
dot-sourced it.  The /bin/sh utility on FreeBSD however behaves
poorly under some circumstances when such a "return" is executed.

In particular, if the "dot" command is contained within a function,
then when a "return" is executed by the script it runs (that is not
itself inside a function), control will return from the function
that contains the "dot" command skipping any statements that might
follow the dot command inside that function.  Commit 99855ddf (first
appearing in v1.8.4.1) addresses this by making the "dot" command
the last line in the function.

Unfortunately the FreeBSD /bin/sh may also execute some statements
in the script run by the "dot" command that appear after the
troublesome "return".  The fix in 99855ddf does not address this
problem.

For example, if you have script1.sh with these contents:

run_script2() {
        . "$(dirname -- "$0")/script2.sh"
        _e=$?
        echo only this line should show
        [ $_e -eq 5 ] || echo expected status 5 got $_e
        return 3
}
run_script2
e=$?
[ $e -eq 3 ] || { echo expected status 3 got $e; exit 1; }

And script2.sh with these contents:

if [ 5 -gt 3 ]; then
        return 5
fi
case bad in *)
        echo always shows
esac
echo should not get here
! :

When running script1.sh (e.g. '/bin/sh script1.sh' or './script1.sh'
after making it executable), the expected output from a POSIX shell
is simply the single line:

only this line should show

However, when run using FreeBSD's /bin/sh, the following output
appears instead:

should not get here
expected status 3 got 1

Not only did the lines following the "dot" command in the run_script2
function in script1.sh get skipped, but additional lines in script2.sh
following the "return" got executed -- but not all of them (e.g. the
"echo always shows" line did not run).

These issues can be avoided by not using a top-level "return" in
script2.sh.  If script2.sh is changed to this:

main() {
        if [ 5 -gt 3 ]; then
                return 5
        fi
        case bad in *)
                echo always shows
        esac
        echo should not get here
        ! :
}
main

Then it behaves the same when using FreeBSD's /bin/sh as when using
other more POSIX compliant /bin/sh implementations.

We fix the git-rebase--*.sh scripts in a similar fashion by moving
the top-level code that contains "return" statements into its own
function and then calling that as the last line in the script.

cb005c1fdf send-email: recognize absolute path on Windows
On Windows, absolute paths might start with a DOS drive prefix,
which these two checks failed to recognize.

Unfortunately, we cannot simply use the file_name_is_absolute
helper in File::Spec::Functions, because Git for Windows has an
MSYS-based Perl, where this helper doesn't grok DOS
drive-prefixes.

So let's manually check for these in that case, and fall back to
the File::Spec-helper on other platforms (e.g Win32 with native
Perl)

39539495ac index-pack: work around thread-unsafe pread()
Multi-threaing of index-pack was disabled with c0f8654
(index-pack: Disable threading on cygwin - 2012-06-26), because
pread() implementations for Cygwin and MSYS were not thread
safe.  Recent Cygwin does offer usable pread() and we enabled
multi-threading with 103d530f (Cygwin 1.7 has thread-safe pread,
2013-07-19).

Work around this problem on platforms with a thread-unsafe
pread() emulation by opening one file handle per thread; it
would prevent parallel pread() on different file handles from
stepping on each other.

Also remove NO_THREAD_SAFE_PREAD that was introduced in c0f8654
because it's no longer used anywhere.

This workaround is unconditional, even for platforms with
thread-safe pread() because the overhead is small (a couple file
handles more) and not worth fragmenting the code.

61a64fff4f Makefile: use curl-config to determine curl flags
curl-config should always be installed alongside a curl distribution,
and its purpose is to provide flags for building against libcurl, so
use it instead of guessing flags and dependent libraries.

Allow overriding CURL_CONFIG to a custom path to curl-config, to
compile against a curl installation other than the first in PATH.

Depending on the set of features curl is compiled with, there may be
more libraries required than the previous two options of -lssl and
-lidn. For example, with a vanilla build of libcurl-7.36.0 on Mac OS X
10.9:

$ ~/d/curl-out-7.36.0/lib/curl-config --libs
-L/Users/dborowitz/d/curl-out-7.36.0/lib -lcurl -lgssapi_krb5 -lresolv -lldap -lz

3994e64d77 transport-helper: fix sync issue on crashes
When a remote helper crashes while pushing we should revert back to the
state before the push, however, it's possible that `git fast-export`
already finished its job, and therefore has exported the marks already.

This creates a synchronization problem because from that moment on
`git fast-{import,export}` will have marks that the remote helper is not
aware of and all further commands fail (if those marks are referenced).

The fix is to tell `git fast-export` to export to a temporary file, and
only after the remote helper has finishes successfully, move to the
final destination.

It's simpler to store the file names directly, and form the fast-export
arguments only when needed, and re-use the same strbuf with a format.

59d3924fbb prompt: fix missing file errors in zsh
zsh seems to have a bug while redirecting the stderr of the 'read'
command:

    % read foo 2>/dev/null <foo
    zsh: no such file or directory: foo

Which causes errors to be displayed when certain files are missing.
Let's add a convenience function to manually check if the file is
readable before calling "read".

ff7a1c677a test: fix t5560 on FreeBSD
Since fd0a8c2e (first appearing in v1.7.0), the
t/t5560-http-backend-noserver.sh test has used a backslash escape
inside a ${} expansion in order to specify a literal '?' character.

Unfortunately the FreeBSD /bin/sh does not interpret this correctly.

In a POSIX compliant shell, the following:

x='one?two?three'
echo "${x#*\?}"

Would be expected to produce this:

two?three

When using the FreeBSD /bin/sh instead you get this:

one?two?three

In fact the FreeBSD /bin/sh treats the backslash as a literal
character to match so that this:

y='one\two\three'
echo "${y#*\?}"

Produces this unexpected value:

wo\three

In this case the backslash is not only treated literally, it also
fails to defeat the special meaning of the '?' character.

Instead, we can use the [...] construct to defeat the special meaning
of the '?' character and match it exactly in a way that works for the
FreeBSD /bin/sh as well as other POSIX /bin/sh implementations.

Changing the example like so:

x='one?two?three'
echo "${x#*[?]}"

Produces the expected output using the FreeBSD /bin/sh.

Therefore, change the use of \? to [?] in order to be compatible with
the FreeBSD /bin/sh which allows t/t5560-http-backend-noserver.sh to
pass on FreeBSD again.

00764ca10e test: fix t7001 cp to use POSIX options
Since 11502468 and 04c1ee57 (both first appearing in v1.8.5), the
t7001-mv test has used "cp -a" to perform a copy in several of the
tests.

However, the "-a" option is not required for a POSIX cp utility and
some platforms' cp utilities do not support it.

The POSIX equivalent of -a is -R -P -p.

Change "cp -a" to "cp -R -P -p" so that the t7001-mv test works
on systems with a cp utility that only implements the POSIX
required set of options and not the "-a" option.

426ddeead6 read-cache.c: verify index file before we opportunistically update it
Before we proceed to opportunistically update the index (often done
by an otherwise read-only operation like "git status" and "git diff"
that internally refreshes the index), we must verify that the
current index file is the same as the one that we read earlier
before we took the lock on it, in order to avoid a possible race.

In the example below git-status does "opportunistic update" and
git-rebase updates the index, but the race can happen in general.

  1. process A calls git-rebase (or does anything that uses the index)

  2. process A applies 1st commit

  3. process B calls git-status (or does anything that updates the index)

  4. process B reads index

  5. process A applies 2nd commit

  6. process B takes the lock, then overwrites process A's changes.

  7. process A applies 3rd commit

As an end result the 3rd commit will have a revert of the 2nd commit.
When process B takes the lock, it needs to make sure that the index
hasn't changed since step 4.

9aa91af036 wrapper.c: add xpread() similar to xread()
It is a common mistake to call read(2)/pread(2) and forget to
anticipate that they may return error with EAGAIN/EINTR when the
system call is interrupted.

We have xread() helper to relieve callers of read(2) from having to
worry about it; add xpread() helper to do the same for pread(2).

Update the caller in the builtin/index-pack.c and the mmap emulation
in compat/.

880111c11b completion: fix completing args of aliased "push", "fetch", etc.
Some commands need the first word to determine the actual action that is
being executed, however, the command is wrong when we use an alias, for
example 'alias.p=push', if we try to complete 'git p origin ', the
result would be wrong because __git_complete_remote_or_refspec() doesn't
know where it came from.

So let's override words[1], so the alias 'p' is override by the actual
command, 'push'.
