Packing objects can be done in parallell nowadays, but it's
only done if the config option pack.threads is set to a value
above 1. Because of that, the code-path used is often not the
most optimal one.
This patch adds a routine to detect the number of online CPU's
at runtime (online_cpus()). When pack.threads (or --threads=) is
given a value of 0, the number of threads is set to the number of
online CPU's. This feature is also documented.
As per Nicolas Pitre's recommendations, the default is still to
run pack-objects single-threaded unless explicitly activated,
either by configuration or by command line parameter.
The routine online_cpus() is a rework of "numcpus.c", written by
one Philip Willoughby <pgw99@doc.ic.ac.uk>. numcpus.c is in the
public domain and can presently be downloaded from
http://csgsoft.doc.ic.ac.uk/numcpus/

"git pack-objects" has the option --max-pack-size to limit the file
size of the packs to a certain amount of bytes. On platforms where
the pack file size is limited by filesystem constraints, it is easy
to forget this option, and this option does not exist for "git gc"
to begin with.
So introduce a config variable to set the default maximum, but make
this overrideable by the command line.

CRLF conversion bears a slight chance of corrupting data.
autocrlf=true will convert CRLF to LF during commit and LF to
CRLF during checkout. A file that contains a mixture of LF and
CRLF before the commit cannot be recreated by git. For text
files this is the right thing to do: it corrects line endings
such that we have only LF line endings in the repository.
But for binary files that are accidentally classified as text the
conversion can corrupt data.
If you recognize such corruption early you can easily fix it by
setting the conversion type explicitly in .gitattributes. Right
after committing you still have the original file in your work
tree and this file is not yet corrupted. You can explicitly tell
git that this file is binary and git will handle the file
appropriately.
Unfortunately, the desired effect of cleaning up text files with
mixed line endings and the undesired effect of corrupting binary
files cannot be distinguished. In both cases CRLFs are removed
in an irreversible way. For text files this is the right thing
to do because CRLFs are line endings, while for binary files
converting CRLFs corrupts data.
This patch adds a mechanism that can either warn the user about
an irreversible conversion or can even refuse to convert. The
mechanism is controlled by the variable core.safecrlf, with the
following values:
- false: disable safecrlf mechanism
- warn: warn about irreversible conversions
- true: refuse irreversible conversions
The default is to warn. Users are only affected by this default
if core.autocrlf is set. But the current default of git is to
leave core.autocrlf unset, so users will not see warnings unless
they deliberately chose to activate the autocrlf mechanism.
The safecrlf mechanism's details depend on the git command. The
general principles when safecrlf is active (not false) are:
- we warn/error out if files in the work tree can modified in an
irreversible way without giving the user a chance to backup the
original file.
- for read-only operations that do not modify files in the work tree
we do not not print annoying warnings.
There are exceptions. Even though...
- "git add" itself does not touch the files in the work tree, the
next checkout would, so the safety triggers;
- "git apply" to update a text file with a patch does touch the files
in the work tree, but the operation is about text files and CRLF
conversion is about fixing the line ending inconsistencies, so the
safety does not trigger;
- "git diff" itself does not touch the files in the work tree, it is
often run to inspect the changes you intend to next "git add". To
catch potential problems early, safety triggers.
The concept of a safety check was originally proposed in a similar
way by Linus Torvalds. Thanks to Dimitry Potapov for insisting
on getting the naked LF/autocrlf=true case right.

This new error mode allows a line to have a carriage return at the
end of the line when checking and fixing trailing whitespace errors.
Some people like to keep CRLF line ending recorded in the repository,
and still want to take advantage of the automated trailing whitespace

remind them that they do have the CR at the end, but these carriage

A set of configuration variables, color.interactive.<slot>, are used to

For perl scripts, Git.pm provides $repo->get_color() method, which takes
the slot name and the default color, and returns the terminal escape
sequence to color the output text. $repo->get_colorbool() method can be
used to check if color is set to be used for a given operation.

When calling 'git pull' with the '--rebase' option, it performs a

As a convenience, you can set the default behavior for a branch by

refspec, and does not have to exactly match the actual lhs of a

branch.<name>.merge is no longer ignored if the remote is configured

only be one ref that gets fetched, but this is more consistant.

The warning message to suggest "Consider running git-status" from
"git-diff" that we experimented with during the 1.5.3 cycle turns
out to be a bad idea. It robbed cache-dirty information from people
who valued it, while still asking users to run "update-index --refresh".
It was hoped that the new behaviour would at least have some educational
value, but not showing the cache-dirty paths like before meant that the
user would not even know easily which paths were cache-dirty, and it
made the need to refresh the index look like even more unnecessary chore.
This commit reinstates the traditional behaviour, but with a twist.
By default, the empty "diff --git" output is totally squelched out
from "git diff" output. At the end of the command, it automatically
runs "update-index --refresh" as needed, without even bothering the
user. In other words, people who do not care about the cache-dirtyness
do not even have to see the warning.
The traditional behaviour to see the stat-dirty output and to bypassing
the overhead of content comparison can be specified by setting the
configuration variable diff.autorefreshindex to false.

The earlier "fix" to setup tracking only when the original ref started
with "refs/remotes" is wrong. You are absolutely allowed to use a
separate layout for your tracking branches. The correct fix, of course,
is to set up tracking information only when there is a matching
remote.<nick>.fetch line containing a colon.
Another corner case was not handled properly. If two remotes write to

Junio noticed that switching on autosetupmerge unilaterally started
cluttering the config for local branches. That is not the original
intention of branch.autosetupmerge, which was meant purely for
convenience when branching off of remote branches, but that semantics
got lost somewhere.
If you still want that "new" behavior, you can switch
branch.autosetupmerge to the value "all". Otherwise, it is interpreted
as a boolean, which triggers setting up defaults _only_ when branching
off of a remote branch, i.e. the originally intended behavior.

So, check the config variable "rerere.enabled". If it is set
to "false" explicitely, do not activate rerere, even if
.git/rr-cache exists. This should help when you want to disable

The absolute minimum bytes that need to be quoted for this
purpose are TAB, LF (and other control characters), double quote

However, we have also always quoted the bytes in high 8-bit
range; this was partly because we were lazy and partly because

This introduces an internal "quote_path_fully" variable, and
core.quotepath configuration variable to control it. When set

setup_gdg is used as abbreviation for setup_git_directory_gently.
The work tree can be specified using the environment variable
GIT_WORK_TREE and the config option core.worktree (the environment
variable has precendence over the config option). Additionally
there is a command line option --work-tree which sets the
environment variable.
setup_gdg does the following now:
GIT_DIR unspecified
repository in .git directory
parent directory of the .git directory is used as work tree,
GIT_WORK_TREE is ignored
GIT_DIR unspecified
repository in cwd
GIT_DIR is set to cwd
see the cases with GIT_DIR specified what happens next and
also see the note below
GIT_DIR specified
GIT_WORK_TREE/core.worktree unspecified
cwd is used as work tree
GIT_DIR specified
GIT_WORK_TREE/core.worktree specified
the specified work tree is used
Note on the case where GIT_DIR is unspecified and repository is in cwd:
GIT_WORK_TREE is used but is_inside_git_dir is always true.
I did it this way because setup_gdg might be called multiple
times (e.g. when doing alias expansion) and in successive calls
setup_gdg should do the same thing every time.
Meaning of is_bare/is_inside_work_tree/is_inside_git_dir:
(1) is_bare_repository
A repository is bare if core.bare is true or core.bare is
unspecified and the name suggests it is bare (directory not
named .git). The bare option disables a few protective
checks which are useful with a working tree. Currently
this changes if a repository is bare:
updates of HEAD are allowed
git gc packs the refs
the reflog is disabled by default
(2) is_inside_work_tree
True if the cwd is inside the associated working tree (if there
is one), false otherwise.
(3) is_inside_git_dir
True if the cwd is inside the git directory, false otherwise.
Before this patch is_inside_git_dir was always true for bare
repositories.
When setup_gdg finds a repository git_config(git_default_config) is
always called. This ensure that is_bare_repository makes use of
core.bare and does not guess even though core.bare is specified.
inside_work_tree and inside_git_dir are set if setup_gdg finds a
repository. The is_inside_work_tree and is_inside_git_dir functions
will die if they are called before a successful call to setup_gdg.

repository at the cost of taking much more wall clock and CPU time.
Today this option causes git-pack-objects to use --no-use-delta
option, and it allows the --window parameter to be set via the
gc.aggressiveWindow configuration parameter.

Add config variables pack.compression and core.loosecompression ,
and switch --compression=level to pack-objects.
Loose objects will be compressed using core.loosecompression if set,
else core.compression if set, else Z_BEST_SPEED.
Packed objects will be compressed using --compression=level if seen,
else pack.compression if set, else core.compression if set,
else Z_DEFAULT_COMPRESSION. This is the "pack compression level".
Loose objects added to a pack undeltified will be recompressed
to the pack compression level if it is unequal to the current
loose compression level by the preceding rules, or if the loose
object was written while core.legacyheaders = true. Newly
deltified loose objects are always compressed to the current
pack compression level.
Previously packed objects added to a pack are recompressed
to the current pack compression level exactly when their
deltification status changes, since the previous pack data
cannot be reused.
In either case, the --no-reuse-object switch from the first
patch below will always force recompression to the current pack
compression level, instead of assuming the pack compression level
hasn't changed and pack data can be reused when possible.
This applies on top of the following patches from Nicolas Pitre:
[PATCH] allow for undeltified objects not to be reused
[PATCH] make "repack -f" imply "pack-objects --no-reuse-object"

Now that we encourage and actively preserve objects in a packed form
more agressively than we did at the time the new loose object format and
core.legacyheaders were introduced, that extra loose object format
doesn't appear to be worth it anymore.
Because the packing of loose objects has to go through the delta match
loop anyway, and since most of them should end up being deltified in
most cases, there is really little advantage to have this parallel loose
object format as the CPU savings it might provide is rather lost in the
noise in the end.
This patch gets rid of core.legacyheaders, preserve the legacy format as
the only writable loose object format and deprecate the other one to
keep things simpler.

The new configuration variable core.deltaBaseCacheLimit allows the
user to control how much memory they are willing to give to Git for
caching base objects of deltas. This is not normally meant to be
a user tweakable knob; the "out of the box" settings are meant to
be suitable for almost all workloads.
We default to 16 MiB under the assumption that the cache is not
meant to consume all of the user's available memory, and that the
cache's main purpose was to cache trees, for faster path limiters
during revision traversal. Since trees tend to be relatively small
objects, this relatively small limit should still allow a large
number of objects.
On the other hand we don't want the cache to start storing 200
different versions of a 200 MiB blob, as this could easily blow
the entire address space of a 32 bit process.
We evict OBJ_BLOB from the cache first (credit goes to Junio) as
we want to favor OBJ_TREE within the cache. These are the objects
that have the highest inflate() startup penalty, as they tend to
be small and thus don't have that much of a chance to ammortize
that penalty over the entire data.

This patch adds support for a dummy remote '.' to avoid having
to declare a fake remote like
[remote "local"]
url = .
fetch = refs/heads/*:refs/heads/*
Such a builtin remote simplifies the operation of "git-fetch",
which will populate FETCH_HEAD but will not pretend that two
repositories are in use, will not create a thin pack, and will
not perform any useless remapping of names. The speed
improvement is around 20%, and it should improve more if
"git-fetch" is converted to a builtin.
To this end, git-parse-remote is grown with a new kind of
remote, 'builtin'. In git-fetch.sh, we treat the builtin remote
specially in that it needs no pack/store operations. In fact,
doing git-fetch on a builtin remote will simply populate
FETCH_HEAD appropriately.
The patch also improves of the --track/--no-track support,
extending it so that branch.<name>.remote items referring '.'
can be created. Finally, it fixes a typo in git-checkout.sh.

Some file systems that can host git repositories and their working copies

This patch enables partial support of symbolic links so that it is possible
to check out a working copy on such a file system. A new flag
core.symlinks (which is true by default) can be set to false to indicate
that the filesystem does not support symbolic links. In this case, symbolic
links that exist in the trees are checked out as small plain files, and
checking in modifications of these files preserve the symlink property in
the database (as long as an entry exists in the index).
Of course, this does not magically make symbolic links work on such defective
file systems; hence, this solution does not help if the working copy relies
on that an entry is a real symbolic link.

So when git-tag looks for "Andy Parkins <andyparkins@gmail.com>";
obviously it's not going to be found.
There shouldn't be a requirement that I use the same form of my name in

my gpg key and informal (Andy) in the repository. Further I might have
multiple keys in my keyring, and might want to use one that doesn't
match up with the address I use in commit messages.
This patch adds a configuration entry "user.signingkey" which, if
present, will be passed to the "-u" switch for gpg, allowing the tag
signing key to be overridden. If the entry is not present, the fallback
is the original method, which means existing behaviour will continue

This makes git-fetch over git native protocol to automatically

commit re-encoding: fix confusion between no and default conversion.
This finally turns on the sliding window behavior for packfile data
access by mapping limited size windows and chaining them under the
packed_git->windows list.
We consider a given byte offset to be within the window only if there
would be at least 20 bytes (one hash worth of data) accessible after
the requested offset. This range selection relates to the contract
that use_pack() makes with its callers, allowing them to access
one hash or one object header without needing to call use_pack()
for every byte of data obtained.
In the worst case scenario we will map the same page of data twice
into memory: once at the end of one window and once again at the
start of the next window. This duplicate page mapping will happen
only when an object header or a delta base reference is spanned
over the end of a window and is always limited to just one page of
duplication, as no sane operating system will ever have a page size
smaller than a hash.
I am assuming that the possible wasted page of virtual address
space is going to perform faster than the alternatives, which
would be to copy the object header or ref delta into a temporary
buffer prior to parsing, or to check the window range on every byte
during header parsing. We may decide to revisit this decision in
the future since this is just a gut instinct decision and has not
actually been proven out by experimental testing.

Rather than hardcoding the maximum number of bytes which can be
mmapped from pack files we should make this value configurable,
allowing the end user to increase or decrease this limit on a
per-repository basis depending on the size of the repository
and the capabilities of their operating system.
In general users should not need to manually tune such a low-level
setting within the core code, but being able to artifically limit
the number of bytes which we can mmap at once from pack files will
make it easier to craft test cases for the new mmap sliding window
implementation.

It is plausible for somebody to want to view the commit log in a
