Now that git_terminal_prompt can cleanly interact with /dev/tty on
Solaris, enable HAVE_DEV_TTY so that this code path is used for
credential reading instead of relying on the crippled getpass().

block-sha1/ is fast on most known platforms. Clarify the Makefile to
be less misleading about that.
Early versions of block-sha1/ explicitly relied on fast htonl() and
fast 32-bit loads with arbitrary alignment. Now it uses those on some
arches but the default behavior is byte-at-a-time access for the sake
of arches like ARM, Alpha, and their kin and it is still pretty fast
on these arches (fast enough to supersede the mozilla SHA1
implementation and the hand-written ARM assembler implementation that
were bundled before).

When I invoke "make block-sha1/sha1.s", 'make' runs $(CC) -S without
specifying where it should put its output and the output ends up in
./sha1.s. Confusing.
Add an -o option to the .s rule to fix this. We were already doing
that for most compiler invocations but had forgotten it for the
assembler listings.

The Cygwin implementation of pread() is not thread-safe since, just
like the emulation provided by compat/pread.c, it uses a sequence of
seek-read-seek calls. In order to avoid failues due to thread-safety
issues, commit b038a61 disables threading when NO_PREAD is defined.
(ie when using the emulation code in compat/pread.c).
We introduce a new build variable, NO_THREAD_SAFE_PREAD, which allows
use to disable the threaded index-pack code on cygwin, in addition to
the above NO_PREAD case.

Makefile: add missing GIT-VERSION-FILE dependency
|
|
In 20fc9bc (Set HTTP user agent to git/GIT_VERSION, 2006-04-04),
http.o started recording GIT_VERSION, but http.o wasn't added
to the list of files that depends on GIT-VERSION-FILE.
Fix this, so mofications to GIT-VERSION-FILE will result in an

Your build platform may support hardlinks but you may prefer not to use
them, e.g. when installing to DESTDIR to make a tarball and untarring on
a filesystem that has poor support for hardlinks.
The Makefile in git-gui project may need to learn to honor the same
setting; it unconditionally creates git-citool by hardlinking git-gui.
* jc/install-no-hardlinks:
Makefile: NO_INSTALL_HARDLINKS

This puts delta resolving on each base on a separate thread, one base
cache per thread. Per-thread data is grouped in struct thread_local.
When running with nr_threads == 1, no pthreads calls are made. The
system essentially runs in non-thread mode.
An experiment on a Xeon 24 core machine with git.git shows that
performance does not increase proportional to the number of cores. So
by default, we use maximum 3 cores. Some numbers with --threads from 1

Your filesystem may support hardlinks, but you may choose not to use them
when installing git-foo builtins and favor symblic links or copies for
whatever reason.
The installation procedure of git-gui/ directory is not touched with this
patch and git-citool still ends up being a hardlink to git-gui, but it
needs to be addressed separately.

A column option string consists of many token separated by either
a space or a comma. A token belongs to one of three groups:
- enabling: always, never and auto
- layout mode: currently plain (which does not layout at all)
- other future tuning flags
git-column can be used to pipe output to from a command that wants
column layout, but not to mess with its own output code. Simpler output
code can be changed to use column layout code directly.

Document the default pager and editor chosen at compile time in the
git-var(1) manpage so users curious about what command _this_ copy of
git will fall back to when EDITOR, VISUAL, and PAGER are unset can
find the answer quickly.
In builds leaving those settings uncustomized, this patch makes the
manpage continue to say "usually vi" and "usually less" so the
formatted documentation is usable for a wide audience including users
of custom builds that change those settings. If you would like your
copy of the docs to be less noncommittal, you will need to set
DEFAULT_PAGER=less and DEFAULT_EDITOR=vi explicitly.

Redo the hashing loop in xdl_hash_record in a way that loads an entire
'long' at a time, using masking tricks to see when and where we found
the terminating '\n'.
I stole inspiration and code from the posts by Linus Torvalds around
https://lkml.org/lkml/2012/3/2/452
https://lkml.org/lkml/2012/3/5/6
His method reads the buffers in sizeof(long) increments, and may thus
overrun it by at most sizeof(long)-1 bytes before it sees the final
newline (or hits the buffer length check). I considered padding out
all buffers by a suitable amount to "catch" the overrun, but
* this does not work for mmap()'d buffers: if you map 4096+8 bytes
from a 4096 byte file, accessing the last 8 bytes results in a
SIGBUS on my machine; and
* it would also be extremely ugly because it intrudes deep into the
unpacking machinery.
So I adapted it to not read beyond the buffer at all. Instead, it
reads the final partial word byte-by-byte and strings it together.
Then it can use the same logic as before to finish the hashing.
So far we enable this only on x86_64, where it provides nice speedup
for diff-related work:
Test origin/next tr/xdiff-fast-hash
-----------------------------------------------------------------------------
4000.1: log -3000 (baseline) 0.07(0.05+0.02) 0.08(0.06+0.02) +14.3%
4000.2: log --raw -3000 (tree-only) 0.37(0.33+0.04) 0.37(0.32+0.04) +0.0%
4000.3: log -p -3000 (Myers) 1.75(1.65+0.09) 1.60(1.49+0.10) -8.6%
4000.4: log -p -3000 --histogram 1.73(1.62+0.09) 1.58(1.49+0.08) -8.7%
4000.5: log -p -3000 --patience 2.11(2.00+0.10) 1.94(1.80+0.11) -8.1%
Perhaps other platforms could also benefit. However it does NOT work
on big-endian systems!

During the testing of the 1.7.10 rc series on Solaris for OpenCSW, it
was discovered that t7006-pager was failing due to finding a bad "sh"
in PATH after a call to execvp("sh", ...). This call was setup by
run_command.c:prepare_shell_cmd.
The PATH in use at the time saw /opt/csw/bin given precedence to
traditional Solaris paths such as /usr/bin and /usr/xpg4/bin. A
package named schilyutils (Joerg Schilling's utilities) was installed
on the build system and it delivered a modified version of the
traditional Solaris /usr/bin/sh as /opt/csw/bin/sh. This version of
sh suffers from many of the same problems as /usr/bin/sh.
The command-specific pager test failed due to the broken "sh" handling
^ as a pipe character. It tried to fork two processes when it
encountered "sed s/^/foo:/" as the pager command. This problem was
entirely dependent on the PATH of the user at runtime.
Possible fixes for this issue are:
1. Use the standard system() or popen() which both launch a POSIX
shell on Solaris as long as _POSIX_SOURCE is defined.
2. The git wrapper could prepend SANE_TOOL_PATH to PATH thus forcing
all unqualified commands run to use the known good tools on the
system.
3. The run_command.c:prepare_shell_command() could use the same
SHELL_PATH that is in the #! line of all all scripts and not rely
on PATH to find the sh to run.
Option 1 would preclude opening a bidirectional pipe to a filter
script and would also break git for Windows as cmd.exe is spawned from
system() (cf. v1.7.5-rc0~144^2, "alias: use run_command api to execute
aliases, 2011-01-07).
Option 2 is not friendly to users as it would negate their ability to
use tools of their choice in many cases. Alternately, injecting
SANE_TOOL_PATH such that it takes precedence over /bin and /usr/bin
(and anything with lower precedence than those paths) as
git-sh-setup.sh does would not solve the problem either as the user
environment could still allow a bad sh to be found. (Many OpenCSW
users will have /opt/csw/bin leading their PATH and some subset would
have schilyutils installed.)
Option 3 allows us to use a known good shell while still honouring the
users' PATH for the utilities being run. Thus, it solves the problem
while not negatively impacting either users or git's ability to run
external commands in convenient ways. Essentially, the shell is a
special case of tool that should not rely on SANE_TOOL_PATH and must
be called explicitly.
With this patch applied, any code path leading to
run_command.c:prepare_shell_cmd can count on using the same sane shell
that all shell scripts in the git suite use. Both the build system
and run_command.c will default this shell to /bin/sh unless
overridden.

Previously it was not possible to iterate revisions twice using the
revision walking api. We add a reset_revision_walk() which clears the
used flags. This allows us to do multiple sequencial revision walks.
We add the appropriate calls to the existing submodule machinery doing
revision walks. This is done to avoid surprises if future code wants to
call these functions more than once during the processes lifetime.

This introduces a performance testing framework under t/perf/. It
tries to be as close to the test-lib.sh infrastructure as possible,
and thus should be easy to get used to for git developers.
The following points were considered for the implementation:
1. You usually want to compare arbitrary revisions/build trees against
each other. They may not have the performance test under
consideration, or even the perf-lib.sh infrastructure.
To cope with this, the 'run' script lets you specify arbitrary
build dirs and revisions. It even automatically builds the revisions
if it doesn't have them at hand yet.
2. Usually you would not want to run all tests. It would take too
long anyway. The 'run' script lets you specify which tests to run;
or you can also do it manually. There is a Makefile for
discoverability and 'make clean', but it is not meant for
real-world use.
3. Creating test repos from scratch in every test is extremely
time-consuming, and shipping or downloading such large/weird repos
is out of the question.
We leave this decision to the user. Two different sizes of test
repos can be configured, and the scripts just copy one or more of
those (using hardlinks for the object store). By default it tries
to use the build tree's git.git repository.
This is fairly fast and versatile. Using a copy instead of a clone
preserves many properties that the user may want to test for, such
as lots of loose objects, unpacked refs, etc.
