18bdec1118 Limit the size of the new delta_base_cache
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.

9debc3241b git-fetch, git-branch: Support local --track via a special remote '.'
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.

78a8d641c1 Add core.symlinks to mark filesystems that do not support symbolic links.
Some file systems that can host git repositories and their working copies
do not support symbolic links. But then if the repository contains a symbolic
link, it is impossible to check out the working copy.

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.

1918278ea1 Allow git-remote to update named groups of remotes
In response to a feature request from Shawn Pearce, this patch allows
a user to update a named group of remotes by using "git remote update
<group>", where the group is defined in the config file by
remotes.<group>.  The default if the named group is not specified is
now fetched group remotes.default, instead of remote.fetch, which is
what had been previously used.

In addition, if remotes.default is not defined, all remotes defined in
the config file will be used, as before, but there is now also
possible to request that a particular repository to be skipped by
default by using the boolean configuration parameter
remote.<name>.skipDefaultUpdate.

d67778eccd Allow the tag signing key to be specified in the config file
I did this:

  $ git tag -s test-sign
  gpg: skipped "Andy Parkins <andyparkins@gmail.com>": secret key not available
  gpg: signing failed: secret key not available
  failed to sign the tag with GPG.

The problem is that I have used the comment field in my key's UID
definition.

  $ gpg --list-keys andy
  pub   1024D/4F712F6D 2003-08-14
  uid                  Andy Parkins (Google) <andyparkins@gmail.com>

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 git repository and my gpg key - I might want to be formal (Andrew) 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
untouched.

af7cf268f0 fetch-pack: remove --keep-auto and make it the default.
This makes git-fetch over git native protocol to automatically
decide to keep the downloaded pack if the fetch results in more
than 100 objects, just like receive-pack invoked by git-push
does.  This logic is disabled when --keep is explicitly given
from the command line, so that a very small clone still keeps
the downloaded pack as before.

The 100 threshold can be adjusted with fetch.unpacklimit
configuration.  We might want to introduce transfer.unpacklimit
to consolidate the two unpacklimit variables, which will be a

and this change makes it so.  I think level 3 is probably pointless

22bac0ea52 Increase packedGit{Limit,WindowSize} on 64 bit systems.
If we have a 64 bit address space we can easily afford to commit

So on these platforms we should increase the default settings of

handle very large projects.

60bb8b1453 Fully activate the sliding window pack access.
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.

77ccc5bbd1 Introduce new config option for mmap limit.
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.
