Junio C Hamano 026aa93818 Revert "prune: --grace=time"
This reverts commit 9b088c4e39.

Protecting 'mature' objects does not make it any safer.  We should
admit that git-prune is inherently unsafe when run in parallel with
other operations without involving unwarranted locking overhead,
and with the latest git, even rebase and reset would not immediately
create crufts anyway.

Matthias Lederhofer 9b088c4e39 prune: --grace=time
This option gives grace period to objects that are unreachable
from the refs from getting pruned.

The default value is 24 hours and may be changed using
gc.prunegrace.

Junio C Hamano 94421474e0 Move traversal of reachable objects into a separate library.
This moves major part of builtin-prune into a separate file,
reachable.c.  It is used to mark the objects that are reachable
from refs, and optionally from reflogs.

The patch looks very large, but if you look at it with diff -C,
which this message is formatted in, most of them are copied
lines and there are very little additions.

Junio C Hamano ca4f293fb4 builtin-prune: separate ref walking from reflog walking.
This is necessary for the next step, because the reason I am
making the connectivity walker into a library is because I want
to use it for cleaning up stale reflog entries.

Junio C Hamano 2430481614 builtin-prune: make file-scope static struct to an argument.
I want to make the first part of 'git prune' that marks the
reachable objects callable as a library, so this starts the
first step toward the goal by making the callchain to pass
rev_info structure as an argument.

No functionality change should be in this step.

Junio C Hamano 16157b8074 builtin-prune: memory diet.
Somehow we forgot to turn save_commit_buffer off while walking
the reachable objects.  Releasing the memory for commit object
data that we do not use matters for large projects (for example,
about 90MB is saved while traversing linux-2.6 history).

Andy Parkins 21f88ac84a Improve git-prune -n output
prune_object() in show_only mode would previously just show the path to the
object that would be deleted.  The path the object is stored in shouldn't be
shown to users, they only know about sha1 identifiers so show that instead.

Further, the sha1 alone isn't that useful for examining what is going to be
deleted.  This patch also adds the object type to the output, which makes it
easy to pick out, say, the commits and use git-show to display them.

J. Bruce Fields 2eb53e65bd Make prune also run prune-packed
Both the git-prune manpage and everday.txt say that git-prune should also prune
unpacked objects that are also found in packs, by running git prune-packed.

Junio thought this was "a regression when prune was rewritten as a built-in."

So modify prune to call prune-packed again.

Junio C Hamano 8da1977554 Tell between packed, unpacked and symbolic refs.
This adds a "int *flag" parameter to resolve_ref() and makes
for_each_ref() family to call callback function with an extra
"int flag" parameter.  They are used to give two bits of
information (REF_ISSYMREF and REF_ISPACKED) about the ref.

Junio C Hamano cb5d709ff8 Add callback data to for_each_ref() family.
This is a long overdue fix to the API for for_each_ref() family
of functions.  It allows the callers to specify a callback data
pointer, so that the caller does not have to use static
variables to communicate with the callback funciton.

The updated for_each_ref() family takes a function of type

	int (*fn)(const char *, const unsigned char *, void *)

and a void pointer as parameters, and calls the function with
the name of the ref and its SHA-1 with the caller-supplied void
pointer as parameters.

The commit updates two callers, builtin-name-rev.c and
builtin-pack-refs.c as an example.

Shawn Pearce 9befac470b Replace uses of strdup with xstrdup.
Like xmalloc and xrealloc xstrdup dies with a useful message if
the native strdup() implementation returns NULL rather than a
valid pointer.

I just tried to use xstrdup in new code and found it to be missing.
However I expected it to be present as xmalloc and xrealloc are
already commonly used throughout the code.

[jc: removed the part that deals with last_XXX, which I am
 finding more and more dubious these days.]

Linus Torvalds a633fca0c0 Call setup_git_directory() much earlier
This changes the calling convention of built-in commands and
passes the "prefix" (i.e. pathname of $PWD relative to the
project root level) down to them.

Linus Torvalds db6296a566 Call setup_git_directory() early
Any git command that expects to work in a subdirectory of a project, and
that reads the git config files (which is just about all of them) needs to
make sure that it does the "setup_git_directory()" call before it tries to
read the config file.

This means, among other things, that we need to move the call out of
"init_revisions()", and into the caller.

This does the mostly trivial conversion to do that.

Linus Torvalds ba84a797e7 builtin "git prune"
This actually removes the objects to be pruned, unless you specify "-n"
(at which point it will just tell you which files it would prune).

This doesn't do the pack-file pruning that the shell-script used to do,
but if somebody really wants to, they could add it easily enough. I wonder
how useful it is, though, considering that "git repack -a -d" is just a
lot more efficient and generates a better end result.
