c97038d1cf git-rerere.txt: grammatical fixups and cleanups
Rewrite the gc section using unresolved and resolved instead of "not
recorded". Add plurals and missing articles. Make some sentences have
consistent tense. Try and be more active by removing "that" and
simplifying sentences.

The terms "hand-resolve" and "hand resolve" were used, so just use "hand
resolve" to be more consistent.

ebc9529f03 bisect: use a PRNG with a bias when skipping away from untestable commits
Using a PRNG (pseudo random number generator) with a bias should be better
than alternating between 3 fixed ratios.

In repositories with many untestable commits it should prevent alternating
between areas where many commits are untestable. The bias should favor
commits that can give more information, so that the bisection process
should not loose much efficiency.

HPA suggested to use a PRNG and found that the best bias is to raise a
ratio between 0 and 1 given by the PRNG to the power 1.5.

An integer square root function is implemented to avoid including
<math.h> and linking with -lm.

A PRNG function is implemented to get the same number sequence on
different machines as suggested by "man 3 rand".

4a4b4cdaab builtin-remote: Make "remote -v" display push urls
Currently, "remote -v" simply lists all urls so that one has to remember
that only the first one is used for fetches, and all are used for
pushes.

Change this so that the role of an url is displayed in parentheses, and
also display push urls.

Example with "one" having one url, "two" two urls, "three" one url and
one pushurl:

one     hostone.com:/somepath/repoone.git (fetch)
one     hostone.com:/somepath/repoone.git (push)
three   http://hostthree.com/otherpath/repothree.git (fetch)
three   hostthree.com:/pathforpushes/repothree.git (push)
two     hosttwo.com:/somepath/repotwo.git (fetch)
two     hosttwo.com:/somepath/repotwo.git (push)
two     hosttwobackup.com:/somewheresafe/repotwo.git (push)

857f8c30d7 builtin-remote: Show push urls as well
Teach builtin remote to show push urls also when asked to
"show" a specific remote.

This improves upon the standard display mode: multiple specified "url"s
mean that the first one is for fetching, all are used for pushing. We
make this clearer now by displaying the first one prefixed with "Fetch
URL", and all "url"s (or, if present, all "pushurl"s) prefixed with
"Push  URL".

Example with "one" having one url, "two" two urls, "three" one url and
one pushurl (URL part only):

* remote one
  Fetch URL: hostone.com:/somepath/repoone.git
  Push  URL: hostone.com:/somepath/repoone.git
* remote two
  Fetch URL: hosttwo.com:/somepath/repotwo.git
  Push  URL: hosttwo.com:/somepath/repotwo.git
  Push  URL: hosttwobackup.com:/somewheresafe/repotwo.git
* remote three
  Fetch URL: http://hostthree.com/otherpath/repothree.git
  Push  URL: hostthree.com:/pathforpushes/repothree.git

Also, adjust t5505 accordingly and make it test for the new output.

f74fe34b96 send-email: fix threaded mails without chain-reply-to
An earlier commit 15da108 ("send-email: 'References:' should only
reference what is sent", 2009-04-13) broke logic to set up threading
information for the next message by rewriting "!" to "not" without
understanding the precedence rules of the language.

Namely,

    ! defined $reply_to || length($reply_to) == 0

was changed to

    not defined $reply_to || length($reply_to) == 0

which is

    not (defined $reply_to || length($reply_to) == 0)

and different from what was intended, which is

    (not defined $reply_to) || (length($reply_to) == 0)

5e9758e296 send-email: fix non-threaded mails
After commit 3e0c4ff (send-email: respect in-reply-to regardless of
threading, 2009-03-01) the variable $thread was only used for prompting
for an "In-Reply-To", but not for controlling whether the "In-Reply-To"
and "References" fields should be written into the email.

Thus these fields were always used beginning with the second mail and it
was not possible to produce non-threaded mails anymore.

However, a later commit 15da108 ("send-email: 'References:' should only
reference what is sent", 2009-04-13) introduced a regression with the
side effect to make non-threaded mails possible again, but only when
--no-chain-reply-to was used.

97af7ff055 parse-remote: function to get the tracking branch to be merge
The only user of get_remote_refs_for_fetch was "git pull --rebase" and
it only wanted the tracking branch to be merge. So, add a simple
function (get_remote_merge_branch) with this new meaning.

No behavior changes. The new function behaves like the old code in
"git pull --rebase". In particular, it only works with the default
refspec mapping and with remote branches, not tags.

61dbb3c441 Makefile: insert SANE_TOOL_PATH to PATH before /bin or /usr/bin
In an earlier patch, we introduced SANE_TOOL_PATH that is prepended to
user's PATH.  This had an unintended consequence of overriding user's
private binary directory that typically comes earlier in the PATH to holds
even saner commands than whatever comes with the system.

For example, a user may have ~/bin that is early in the path and contains
a shell script "vi" that launches system's /bin/vi with specific options.
Prepending SANE_TOOL_PATH to the PATH that happens to have "vi" in it
defeats such customization.

This fixes the issue by inserting SANE_TOOL_PATH just before /bin or
/usr/bin appears on the PATH.

f39d6ee2aa Documentation: mention 'git stash pop --index' option explicitly
'git stash pop' supports the '--index' option since its initial
implementation (bd56ff54, git-stash: add new 'pop' subcommand,
2008-02-22), but its documentation does not mention it explicitly.
Moreover, both the usage shown by 'git stash -h' and the synopsis
section in the man page imply that 'git stash pop' does not have an
'--index' option.

First, this patch corrects the usage and the synopsis section.

Second, the patch moves the description of the '--index' option to the
'git stash pop' section in the documentation, and refers to it from
the 'git stash apply' section.  This way it follows the intentions of
commit d1836637 (Documentation: teach stash/pop workflow instead of
stash/apply, 2009-05-28), as all 'git stash pop'-related documentation
will be in one place without references to 'git stash apply'.

encoding names to assist older platforms.  The charset attribute of MIME

a3a8262bf6 git-send-email.perl: improve detection of MIME encoded-words
According to rfc2047, an encoded word has the following form:

   encoded-word = "=?" charset "?" encoding "?" encoded-text "?="

   charset = token

   encoding = token

   token = <Any CHAR except SPACE, CTLs, and especials>

   especials = "(" / ")" / "<" / ">" / "@" / "," / ";" / ":" / "
               <"> / "/" / "[" / "]" / "?" / "." / "="

   encoded-text = <Any printable ASCII character other than "?"
                     or SPACE>

And rfc822 defines CHARs and CTLs as:

    CHAR = <any ASCII character> ; (  0-177,  0.-127.)

    CTL = <any ASCII control     ; (  0- 37,  0.- 31.)
           character and DEL>    ; (    177,     127.)

The original code only detected rfc2047 encoded strings when the charset
was UTF-8.  This patch generalizes the matching expression and breaks the
check for an rfc2047 encoded string into its own function.  There's no real
functional change, since any properly rfc2047 encoded string would have
fallen through the remaining 'if' statements and been returned unchanged.

3ef67cf250 fetch-pack: close output channel after sideband demultiplexer terminates
fetch-pack runs the sideband demultiplexer using start_async(). This
facility requires that the asynchronously executed function closes the
output file descriptor (see Documentation/technical/api-run-command.txt).
But the sideband demultiplexer did not do that. This fixes it.

In certain error situations this could lock up a fetch operation on
Windows because the asynchronous function is run in a thread; by not
closing the output fd the reading end never got EOF and waited for more
data indefinitely. On Unix this is not a problem because the asynchronous
function is run in a separate process, which exits after the function ends
and so implicitly closes the output.

Since the pack that is sent over the wire encodes the number of objects in
the stream, during normal operation the reading end knows when the stream
ends and terminates by itself, and does not lock up.

a21077e75f Fix warnings in nedmalloc when compiling with GCC 4.4.0
Nedmalloc's source code has a cute #define construct to avoid inserting
an if() statement, because that might interact badly with enclosing if()
statements.  However, GCC > 4 complains with a "warning: value computed
is not used".  So we cast the result to "void".

GCC also does not understand the Visual C++ specific pragmas, so we need
to disable them for MinGW.

We need to include malloc.h on Windows even if we happen to compile the
stuff as a MinGW program.  Otherwise the function declaration of alloca()
is missing.

cb319c3631 symlinks.c: small style cleanup
Add {}-braces around an else-part, where the if-part already has
{}-braces.

And, also remove some unnecessary "return;"-statements at the end of
"void foo()"-functions.

801a011dcf Documentation: refer to gitworkflows(7) from tutorial and git(1)
Add references to the gitworkflows(7) manpage added in f948dd8
(Documentation: add manpage about workflows, 2008-10-19) to both
gittutorial(1) and git(1), so that new users might actually discover
and read it.

Noticed by Randal L. Schwartz.

73bb33a94e daemon: Strictly parse the "extra arg" part of the command
Since 1.4.4.5 (49ba83fb67 "Add virtualization support to git-daemon")
git daemon enters an infinite loop and never terminates if a client
hides any extra arguments in the initial request line which is not
exactly "\0host=blah\0".

Since that change, a client must never insert additional extra
arguments, or attempt to use any argument other than "host=", as
any daemon will get stuck parsing the request line and will never
complete the request.

Since the client can't tell if the daemon is patched or not, it
is not possible to know if additional extra args might actually be
able to be safely requested.

If we ever need to extend the git daemon protocol to support a new
feature, we may have to do something like this to the exchange:

  # If both support git:// v2
  #
  C: 000cgit://v2
  S: 0010ok host user
  C: 0018host git.kernel.org
  C: 0027git-upload-pack /pub/linux-2.6.git
  S: ...git-upload-pack header...

  # If client supports git:// v2, server does not:
  #
  C: 000cgit://v2
  S: <EOF>

  C: 003bgit-upload-pack /pub/linux-2.6.git\0host=git.kernel.org\0
  S: ...git-upload-pack header...

This requires the client to create two TCP connections to talk to
an older git daemon, however all daemons since the introduction of
daemon.c will safely reject the unknown "git://v2" command request,
so the client can quite easily determine the server supports an
older protocol.

34aec9f573 parse-options: simplify usage argh handling
Simplify the argh printing by simply calling usage_argh() if the option
can take an argument. Update macros defined in parse-options.h to set
the PARSE_OPT_NOARG flag.

The only other user of custom non-argument taking options is git-apply
(in this case OPTION_BOOLEAN for deprecated options). Update it to set
the PARSE_OPT_NOARG flag.

Thanks to Ren辿 Scharfe for the suggestion and starter patch.
