completion: avoid ls-remote in certain scenarios

It's _very_ slow in many cases, and there's really no point in fetching
*everything* from the remote just for completion. In many cases it might
be faster for the user to type the whole thing.

If the user manually specifies 'refs/*', then the full ls-remote
completion is triggered.

unpack-trees: create working copy of merge entry in merged_entry

Duplicate the merge entry right away and work with that instead of
modifying the entry we got and duplicating it only at the end of
the function. Then mark that pointer const to document that we
don't modify the referenced cache_entry.

This change is safe because all existing merge functions call
merged_entry just before returning (or not at all), i.e. they don't
care about changes to the referenced cache_entry after the call.
unpack_nondirectories and unpack_index_entry, which call the merge
functions through call_unpack_fn, aren't interested in such changes
neither.

The change complicates merged_entry a bit because we have to free the
copy if we error out, but allows callers to pass a const pointer.

refs: document the lifetime of the args passed to each_... Michael Haggerty Sat, 25 May 2013 09:08:24 +0000 (11:08 +0200)

refs: document the lifetime of the args passed to each_ref_fn

The lifetime of the memory pointed to by the refname and sha1
arguments to each_ref_fn was never documented, but some callers used
to assume that it was essentially permanent. In fact the API does
*not* guarantee that these objects live beyond a single callback
invocation.

In the current code, the lifetimes are bound together with the
lifetimes of the ref_caches. Since these are usually long, the
callers usually got away with their sloppiness. But even today, if a
ref_cache is invalidated the memory can be freed. And planned changes
to reference caching, needed to eliminate race conditions, will
probably need to shorten the lifetimes of these objects.

The commits leading up to this have (hopefully) fixed all of the
callers of the for_each_ref()-like functions. This commit does the
last step: documents what each_ref_fn callbacks can assume about
object lifetimes.

object_array_entry: fix memory handling of the name... Michael Haggerty Sat, 25 May 2013 09:08:14 +0000 (11:08 +0200)

object_array_entry: fix memory handling of the name field

Previously, the memory management of the object_array_entry::name
field was inconsistent and undocumented. object_array_entries are
ultimately created by a single function, add_object_array_with_mode(),
which has an argument "const char *name". This function used to
simply set the name field to reference the string pointed to by the
name parameter, and nobody on the object_array side ever freed the
memory. Thus, it assumed that the memory for the name field would be
managed by the caller, and that the lifetime of that string would be
at least as long as the lifetime of the object_array_entry. But
callers were inconsistent:

* Some passed pointers to constant strings or argv entries, which was
OK.

* Some passed pointers to newly-allocated memory, but didn't arrange
for the memory ever to be freed.

* Some passed the return value of sha1_to_hex(), which is a pointer to
a statically-allocated buffer that can be overwritten at any time.

* Some passed pointers to refnames that they received from a
for_each_ref()-type iteration, but the lifetimes of such refnames is
not guaranteed by the refs API.

Bring consistency to this mess by changing object_array to make its
own copy for the object_array_entry::name field and free this memory
when an object_array_entry is deleted from the array.

Many callers were passing the empty string as the name parameter, so
as a performance optimization, treat the empty string specially.
Instead of making a copy, store a pointer to a statically-allocated
empty string to object_array_entry::name. When deleting such an
entry, skip the free().

Change the callers that were already passing copies to
add_object_array_with_mode() to either skip the copy, or (if the
memory needed to be allocated anyway) freeing the memory itself.

A part of this commit effectively reverts

necessary) is now done at a deeper level.

dir.c: fix ignore processing within not-ignored directories

As of 95c6f271 "dir.c: unify is_excluded and is_path_excluded APIs", the
is_excluded API no longer recurses into directories that match an ignore
pattern, and returns the directory's ignored state for all contained paths.

This is OK for normal ignore patterns, i.e. ignoring a directory affects
the entire contents recursively.

Unfortunately, this also "works" for negated ignore patterns ('!dir'), i.e.
the entire contents is "not-ignored" recursively, regardless of ignore
patterns that match the contents directly.

In prep_exclude, skip recursing into a directory only if it is really
ignored (i.e. the ignore pattern is not negated).

wildmatch: properly fold case everywhereAnthony Ramine Thu, 30 May 2013 10:19:10 +0000 (12:19 +0200)

wildmatch: properly fold case everywhere

Case folding is not done correctly when matching against the [:upper:]
character class and uppercased character ranges (e.g. A-Z).
Specifically, an uppercase letter fails to match against any of them
when case folding is requested because plain characters in the pattern
and the whole string are preemptively lowercased to handle the base case
fast.

That optimization is kept and ISLOWER() is used in the [:upper:] case
when case folding is requested, while matching against a character range
is retried with toupper() if the character was lowercase, as the bounds
of the range itself cannot be modified (in a case-insensitive context,
[A-_] is not equivalent to [a-_]).

Test 'commit --only' after 'checkout --orphan'Thomas Rast Sat, 1 Jun 2013 11:02:00 +0000 (13:02 +0200)

Test 'commit --only' after 'checkout --orphan'

There are some index handling subtleties in 'commit --only' that are
best tested when we have an existing index, but an unborn or empty
HEAD. These circumstances are easily produced by 'checkout --orphan',

sha1_name: fix error message for @{<N>}, @{<date>}

Currently, when we try to resolve @{<N>} or @{<date>} when the reflog
doesn't go back far enough, we get errors like:

# on branch master
$ git show @{10000}
fatal: Log for '' only has 7 entries.

$ git show @{10000.days.ago}
warning: Log for '' only goes back to Tue, 21 May 2013 14:14:45 +0530.
...

# detached HEAD case
$ git show @{10000}
fatal: Log for '' only has 2005 entries.

$ git show master@{10000}
fatal: Log for 'master' only has 7 entries.

The empty string '' is confusing and does not convey information
about whose logs we are inspecting. Change this so that we get:

# on branch master
$ git show @{10000}
fatal: Log for 'master' only has 7 entries.

$ git show @{10000.days.ago}
warning: Log for 'master' only goes back to Tue, 21 May 2013 14:14:45 +0530.
...

# detached HEAD case
$ git show @{10000}
fatal: Log for 'HEAD' only has 2005 entries.

$ git show master@{10000}
fatal: Log for 'master' only has 7 entries.

Also one of the message strings given to die() now points into
real_ref that was not used in that fashion, so stop freeing the
underlying storage for it.

On MinGW, sparse issues an "'get_st_mode_bits' not declared. Should
it be static?" warning. The MinGW and MSVC builds do not see the
declaration of this function, within git-compat-util.h, due to its
placement within an preprocessor conditional.

In order to suppress the warning, we simply move the declaration to

push: make push.default = current use resolved HEADRamkumar Ramachandra Wed, 29 May 2013 19:21:51 +0000 (00:51 +0530)

push: make push.default = current use resolved HEAD

With this change, the output of the push (with push.default set to
current) changes subtly from:

$ git push
...
* [new branch] HEAD -> push-current-head

to:

$ git push
...
* [new branch] push-current-head -> push-current-head

This patch was written with a different motivation. There is a problem
unique to push.default = current:

# on branch push-current-head
$ git push
# on another terminal
$ git checkout master
# return to the first terminal
# the push tried to push master!

This happens because the 'git checkout' on the second terminal races
with the 'git push' on the first terminal. Although this patch does not
solve the core problem (there is still no guarantee that 'git push' on
the first terminal will resolve HEAD before 'git checkout' changes HEAD
on the second), it works in practice.

push: fail early with detached HEAD and currentRamkumar Ramachandra Wed, 29 May 2013 19:21:50 +0000 (00:51 +0530)

push: fail early with detached HEAD and current

Setting push.default to current adds the refspec "HEAD" for the
transport layer to handle. If "HEAD" doesn't resolve to a branch (and
since no refspec rhs is specified), the push fails after some time with
a cryptic error message:

$ git push
error: unable to push to unqualified destination: HEAD
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to 'git@github.com:artagnon/git'

Fail early with a nicer error message:

$ git push
fatal: You are not currently on a branch.
To push the history leading to the current (detached HEAD)
state now, use

git push ram HEAD:<name-of-remote-branch>

Just like in the upstream and simple cases.

However, the set of files to be copied back is computed
differently between --symlinks and --no-symlinks modes. The
former checks all paths that start out as identical to the
working tree file, while the latter checks paths that
already had a local modification in the working tree,
allowing changes made in the tree diff program to paths that
did not have any local change to be lost.

rebase: implement --[no-]autostash and rebase.autostashRamkumar Ramachandra Sun, 12 May 2013 11:56:41 +0000 (17:26 +0530)

rebase: implement --[no-]autostash and rebase.autostash

This new feature allows a rebase to be executed on a dirty worktree or
index. It works by creating a temporary "dangling merge commit" out
of the worktree and index changes (via 'git stash create'), and
automatically applying it after a successful rebase or abort.

rebase stores the SHA-1 hex of the temporary merge commit, along with
the rest of the rebase state, in either
.git/{rebase-merge,rebase-apply}/autostash depending on the kind of
rebase. Since $state_dir is automatically removed at the end of a
successful rebase or abort, so is the autostash.

The advantage of this approach is that we do not affect the normal
stash's reflogs, making the autostash invisible to the end-user. This
means that you can use 'git stash' during a rebase as usual.

When the autostash application results in a conflict, we push
$state_dir/autostash onto the normal stash and remove $state_dir
ending the rebase. The user can inspect the stash, and pop or drop at
any time.

Most significantly, this feature means that a caller like pull (with
pull.rebase set to true) can easily be patched to remove the
require_clean_work_tree restriction.

get the update. By the time we return from diff_tree_combined,
rev->diffopt->pathspec->items points to an invalid memory address. We
get a segfault next time we try to access that pathspec.

Instead, along with the copy of diffopts, make a copy pathspec->items as
well.

object_array_remove_duplicates(): rewrite to reduce copying

The old version copied one entry to its destination position, then
deleted any matching entries from the tail of the array. This
required the tail of the array to be copied multiple times. It didn't
affect the complexity of the algorithm because the whole tail has to
be searched through anyway. But all the copying was unnecessary.

Instead, check for the existence of an entry with the same name in the
*head* of the list before copying an entry to its final position.
This way each entry has to be copied at most one time.

cmd_diff(): make it obvious which cases are exclusive of each other

At first glance the OBJ_COMMIT, OBJ_TREE, and OBJ_BLOB cases look like
they might be mutually exclusive. But the OBJ_COMMIT case doesn't end
the loop iteration with "continue" like the other two cases, but
rather falls through. So use if...else if...else construct to make it
more obvious that only the last two cases are mutually exclusive.

cmd_diff(): rename local variable "list" -> "entry"

It's not a list, it's an array entry.

cmd_diff(): use an object_array for holding trees

Change cmd_diff() to use a (struct object_array) for holding the trees
that it accumulates, rather than rolling its own equivalent.

Incidentally, this change removes a hard-coded limit of 100 trees in
combined diff, not that it matters in practice.

builtin_diff_tree(): make it obvious that function wants two entries

Instead of accepting an array and using exactly two elements from the
array, take two single (struct object_array_entry *) arguments.

Instead of assuming that the memory pointed to by the name argument
will live forever, make a local copy of it before storing it in the

prune-packed: avoid implying "1" is DRY_RUN in prune_pa... Nguyễn Thái Ngọc Duy Mon, 27 May 2013 11:18:47 +0000 (18:18 +0700)

prune-packed: avoid implying "1" is DRY_RUN in prune_packed_objects()

Commit b60daf0 (Make git-prune-packed a bit more chatty. - 2007-01-12)
changes the meaning of prune_packed_objects()'s argument, from "dry
run or not dry run" to a bitmap.

It however forgot to update prune_packed_objects() caller in
builtin/prune.c to use new DRY_RUN macro. It's fine (for a long time!)
but there is a risk that someday someone may change the value of
DRY_RUN to something else and builtin/prune.c suddenly breaks. Avoid
that possibility.

While at there, change "opts == VERBOSE" to "opts & VERBOSE" as there
is no obvious reason why we only be chatty when DRY_RUN is not set.

fetch: don't try to update unfetched tracking refs

Since commit f269048 (fetch: opportunistically update tracking refs,
2013-05-11) we update tracking refs opportunistically when fetching
remote branches. However, if there is a configured non-pattern refspec
that does not match any of the refspecs given on the command line then a
fatal error occurs.

Fix this by setting the "missing_ok" flag when calling get_fetch_map.
