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.

We only need to do these two tasks
git gc --auto
rm -fr "$dotest"
ourselves if the script was invoked as a standalone program; when
invoked with --rebasing (from git-rebase--am.sh), cascade control back
to the ultimate caller git-rebase.sh to do this for us.

On successful completion of a rebase in git-rebase--$backend.sh, the
$backend script cleans up on its own and exits. The cleanup routine
is however, independent of the $backend, and each $backend script
unnecessarily duplicates this work:
rm -rf "$state_dir"
git gc --auto
Prepare git-rebase.sh for later patches that return control from each
$backend script back to us, for performing this generic cleanup
routine. The code that this patch adds is currently unreachable, and
will only start to be used when git-rebase--$backend.sh scripts are
taught to return control in later patches.
Another advantage is that git-rebase.sh can implement a generic
finish_rebase() to possibly do additional tasks in addition to the
cleanup.

In preparation for a later patch that will create $state_dir/autostash
in git-rebase.sh before anything else can happen, change a `mkdir
$state_dir` call to `mkdir -p $state_dir`. The change is safe,
because this is not a test to detect an in-progress rebase (that is
already done much earlier in git-rebase.sh).

In preparation for a later patch that creates $dotest/autostash in
git-rebase.sh before anything else happens, don't assume that the
presence of a $dotest directory implies the existence of the
$dotest/next and $dotest/last files. Look for them explicitly.

In the !delta_data error path of unpack_entry(), we run free(base).
This became a window for use-after-free() in abe601b (sha1_file:
remove recursion in unpack_entry, 2013-03-27), as follows:
Before abe601b, we got the 'base' from cache_or_unpack_entry(..., 0);
keep_cache=0 tells it to also remove that entry. So the 'base' is at
this point not cached, and freeing it in the error path is the right
thing.
After abe601b, the structure changed: we use a three-phase approach
where phase 1 finds the innermost base or a base that is already in
the cache. In phase 3 we therefore know that all bases we unpack are
not part of the delta cache yet. (Observe that we pop from the cache
in phase 1, so this is also true for the very first base.) So we make
no further attempts to look up the bases in the cache, and just call
add_delta_base_cache() on every base object we have assembled.
But the !delta_data error path remained unchanged, and now calls
free() on a base that has already been entered in the cache. This
means that there is a use-after-free if we later use the same base
again.
So remove that free(); we are still going to use that data.

So that we can have a nice zsh completion output:
% git <tab>
add -- add file contents to the index
bisect -- find by binary search the change that introduced a bug
branch -- list, create, or delete branches
checkout -- checkout a branch or paths to the working tree
clone -- clone a repository into a new directory
commit -- record changes to the repository
diff -- show changes between commits, commit and working tree, etc
fetch -- download objects and refs from another repository
grep -- print lines matching a pattern
init -- create an empty Git repository or reinitialize an existing one
log -- show commit logs
merge -- join two or more development histories together
mv -- move or rename a file, a directory, or a symlink
pull -- fetch from and merge with another repository or a local branch
push -- update remote refs along with associated objects
rebase -- forward-port local commits to the updated upstream head
reset -- reset current HEAD to the specified state
rm -- remove files from the working tree and from the index
show -- show various types of objects
status -- show the working tree status
tag -- create, list, delete or verify a tag object signed with GPG
And other niceties, like 'git --git-dir=<tab>' showing only directories.
For the rest, the bash completion stuff is still used.
Also, add my copyright, since this more than a thin wrapper.

There should be no functional changes.
The only reason I wrapped this code around a sub-function is because zsh
did the same in it's bashcompinit script in order to declare the special
variable 'words' as hidden, but only in this context.
There's no need for that any more since we access __git_main directly,
so 'words' is not modified, so there's no need for the sub-function.
In zsh mode the array indexes are different though.

We call File::Temp's "tempfile" function as a class method, but it was
never designed to be called this way. Older versions seemed to
tolerate it, but as of File::Temp 0.23, it blows up like this:
$ git svn fetch
'tempfile' can't be called as a method at .../Git.pm line 1117.
Fix it by calling it as a regular function, just inside the File::Temp
namespace.

Commit d24fbca (Remove Git's support for smoke testing - 2011-12-23)
removed the smoke test support from the test suite but it was
re-added by commit 342e9ef (Introduce a performance testing
framework - 2012-02-17). This appears to be the result of a
mis-rebase, since re-adding the smoke testing infrastructure does
not relate to the subject of that commit.
The current 'smoke' target is broken since the 'harness' script it
uses no longer exists, so just reapply this section of commit d24fbca
and remove all of the smoke testing section in the makefile.

* nd/pretty-formats:
pretty: Fix bug in truncation support for %>, %< and %><
|
|
Some systems experience failures in t4205-*.sh (tests 18-20, 27)
which all relate to the use of truncation with the %< padding
placeholder. This capability was added in the commit a7f01c6b
("pretty: support truncating in %>, %< and %><", 19-04-2013).
The truncation support was implemented with the assistance of a
new strbuf function (strbuf_utf8_replace). This function contains
the following code:
strbuf_attach(sb_src, strbuf_detach(&sb_dst, NULL),
sb_dst.len, sb_dst.alloc);
Unfortunately, this code is subject to unspecified behaviour. In
particular, the order of evaluation of the argument expressions
(along with the associated side effects) is not specified by the
C standard. Note that the second argument expression is a call to
strbuf_detach() which, as a side effect, sets the 'len' and 'alloc'
fields of the sb_dst argument to zero. Depending on the order of
evaluation of the argument expressions to the strbuf_attach call,
this can lead to assigning an empty string to 'sb_src'.
In order to remove the undesired behaviour, we replace the above
line of code with:
strbuf_swap(sb_src, &sb_dst);
strbuf_release(&sb_dst);
which achieves the desired effect without provoking unspecified
behaviour.
