After a unique command or option is completed, in most cases it is a
good thing to add a trailing a space, but sometimes it doesn't make
sense, e.g. when the completed word is an option taking an argument
('--option=') or a configuration section ('core.'). Therefore the
completion script uses the '-o nospace' option to prevent bash from
automatically appending a space to unique completions, and it has the
__gitcomp() function to add that trailing space only when necessary.
See 72e5e989 (bash: Add space after unique command name is completed.,
2007-02-04), 78d4d6a2 (bash: Support unique completion on git-config.,
2007-02-04), and b3391775 (bash: Support unique completion when
possible., 2007-02-04).
__gitcomp() therefore iterates over all possible completion words it
got as argument, and checks each word whether a trailing space is
necessary or not. This is ok for commands, options, etc., i.e. when
the number of words is relatively small, but can be noticeably slow
for large number of refs. However, while options might or might not
need that trailing space, refs are always handled uniformly and always
get that trailing space (or a trailing '.' for 'git config
branch.<head>.'). Since refs listed by __git_refs() & co. are
separated by newline, this allows us some optimizations with
'compgen'.
So, add a specialized variant of __gitcomp() that only deals with
possible completion words separated by a newline and uniformly appends
the trailing space to all words using 'compgen -S " "' (or any other
suffix, if specified), so no iteration over all words is needed. But
we need to fiddle with IFS, because the default IFS containing a space
would cause the added space suffix to be stripped off when compgen's
output is stored in the COMPREPLY array. Therefore we use only
newline as IFS, hence the requirement for the newline-separated
possible completion words.
Convert all callsites of __gitcomp() where it's called with refs, i.e.
when it gets the output of either __git_refs(), __git_heads(),
__git_tags(), __git_refs2(), __git_refs_remotes(), or the odd 'git
for-each-ref' somewhere in _git_config(). Also convert callsites
where it gets other uniformly handled newline separated word lists,
i.e. either remotes from __git_remotes(), names of set configuration
variables from __git_config_get_set_variables(), stashes, or commands.
Here are some timing results for dealing with 10000 refs.
Before:
$ refs="$(__git_refs ~/tmp/git/repo-with-10k-refs/)"
$ time __gitcomp "$refs"
real 0m1.134s
user 0m1.060s
sys 0m0.130s

Allow the user to check the patch set before it is commited to SVN. It is
then possible to accept/discard one patch, accept all, or quit.
This interactive mode is similar with 'git send email' behaviour. However,
'git svn dcommit' returns as soon as one patch is discarded.
Part of the code was taken from git-send-email.perl (see 'ask' function)

cec5dae (use new Git::config_path() for aliasesfile, 2011-09-30) broke
the expansion of aliases.
This was caused by treating %config_path_settings, newly introduced in
said patch, like %config_bool_settings instead of like %config_settings.
Copy from %config_settings, making it more readable.
While at it add basic test for expansion of aliases, and for path
expansion, which would catch this error.
Nb. there were a few issues that were responsible for this error:
1. %config_bool_settings and %config_settings despite similar name have
different semantic.
%config_bool_settings values are arrays where the first element is
(reference to) the variable to set, and second element is default
value... which admittedly is a bit cryptic. More readable if more
verbose option would be to use hash reference, e.g.:
%config_settings values are either either reference to scalar variable
or reference to array. In second case it means that option (or config
option) is multi-valued. BTW. this is similar to what Getopt::Long does.
2. In cec5dae (use new Git::config_path() for aliasesfile, 2011-09-30)
the setting "aliasesfile" was moved from %config_settings to newly
introduced %config_path_settings. But the loop that parses settings
from %config_path_settings was copy'n'pasted *wrongly* from
%config_bool_settings instead of from %config_settings.
It looks like cec5dae author cargo-culted this change...

refs.c: ensure struct whose member may be passed to realloc is initialized
The variable "refs" is allocated on the stack but is not initialized. It
is passed to read_packed_refs(), and its struct members may eventually be
passed to add_ref() and ALLOC_GROW(). Since the structure has not been

initialize it.

Makefile: fix permissions of mergetools/ checked out with permissive umask
Ever since mergetool--lib was split into multiple files in
v1.7.7-rc0~3^2~1 (2011-08-18), the Makefile takes care to reset umask
and use tar --no-owner when installing merge tool definitions to
$(gitexecdir)/mergetools/. Unfortunately it does not take into
account the possibility that the permission bits of the files being
copied might already be wrong.
Rather than fixing the "tar" incantation and making it even more
complicated, let's just use the "install" utility. This only means
losing the ability to install executables and subdirectories of
mergetools/, which wasn't used.
Noticed by installing from a copy of git checked out with umask 002.

fix phantom untracked files when core.ignorecase is set
When core.ignorecase is turned on and there are stale index
entries, "git commit" can sometimes report directories as
untracked, even though they contain tracked files.
You can see an example of this with:
# make a case-insensitive repo
git init repo && cd repo &&
git config core.ignorecase true &&
# with some tracked files in a subdir
mkdir subdir &&
> subdir/one &&
> subdir/two &&
git add . &&
git commit -m base &&
# now make the index entries stale
touch subdir/* &&
# and then ask commit to update those entries and show
# us the status template
git commit -a
which will report "subdir/" as untracked, even though it
clearly contains two tracked files. What is happening in the
commit program is this:
1. We load the index, and for each entry, insert it into the index's
name_hash. In addition, if ignorecase is turned on, we make an
entry in the name_hash for the directory (e.g., "contrib/"), which
uses the following code from 5102c61's hash_index_entry_directories:
Note that we only add the directory entry if there is not already an
entry.
2. We run add_files_to_cache, which gets updated information for each
cache entry. It helpfully inserts this information into the cache,
which calls replace_index_entry. This in turn calls
remove_name_hash() on the old entry, and add_name_hash() on the new
one. But remove_name_hash doesn't actually remove from the hash, it
only marks it as "no longer interesting" (from cache.h):
/*
* We don't actually *remove* it, we can just mark it invalid so that
* we won't find it in lookups.
*
* Not only would we have to search the lists (simple enough), but
* we'd also have to rehash other hash buckets in case this makes the
* hash bucket empty (common). So it's much better to just mark
* it.
*/
static inline void remove_name_hash(struct cache_entry *ce)
{
ce->ce_flags |= CE_UNHASHED;
}
This is OK in the specific-file case, since the entries in the hash
form a linked list, and we can just skip the "not here anymore"
entries during lookup.
But for the directory hash entry, we will _not_ write a new entry,
because there is already one there: the old one that is actually no
longer interesting!
3. While traversing the directories, we end up in the
directory_exists_in_index_icase function to see if a directory is
interesting. This in turn checks index_name_exists, which will
look up the directory in the index's name_hash. We see the old,
deleted record, and assume there is nothing interesting. The
directory gets marked as untracked, even though there are index
entries in it.
Having a single cache entry that represents the directory is
not enough; that entry may go away if the index is changed.
It may be tempting to say that the problem is in our removal
method; if we removed the entry entirely instead of simply
marking it as "not here anymore", then we would know we need
to insert a new entry. But that only covers this particular
case of remove-replace. In the more general case, consider
something like this:
1. We add "foo/bar" and "foo/baz" to the index. Each gets
their own entry in name_hash, plus we make a "foo/"
entry that points to "foo/bar".
2. We remove the "foo/bar" entry from the index, and from
the name_hash.
3. We ask if "foo/" exists, and see no entry, even though
"foo/baz" exists.
So we need that directory entry to have the list of _all_
cache entries that indicate that the directory is tracked.
So that implies making a linked list as we do for other
entries, like:
But that's not right either. In fact, it shows a second bug
in the current code, which is that the "ce->next" pointer is
supposed to be linking entries for a specific filename
entry, but here we are overwriting it for the directory
entry. So the same cache entry ends up in two linked lists,
but they share the same "next" pointer.
As it turns out, this second bug can't be triggered in the
current code. The "if (pos)" conditional is totally dead
code; pos will only be non-NULL if there was an existing
hash entry, and we already checked that there wasn't one
through our call to lookup_hash.
But fixing the first bug means taking out that call to
lookup_hash, which is going to activate the buggy dead code,
and we'll end up splicing the two linked lists together.
So we need to have a separate next pointer for the list in
the directory bucket, and we need to traverse that list in
index_name_exists when we are looking up a directory.
This bloats "struct cache_entry" by a few bytes. Which is
annoying, because it's only necessary when core.ignorecase
is enabled. There's not an easy way around it, short of
separating out the "next" pointers from cache_entry entirely
(i.e., having a separate "cache_entry_list" struct that gets
stored in the name_hash). In practice, it probably doesn't
matter; we have thousands of cache entries, compared to the
millions of objects (where adding 4 bytes to the struct
actually does impact performance).

Avoid a getpwuid() call (which contacts the network if the password

reverse DNS lookup if the user has already chosen a name and email

This should slightly speed up commands like "git commit". More
importantly, it improves error reporting when computation of the
default ident string does not go smoothly. For example, after
detecting a problem (e.g., "warning: cannot open /etc/mailname:
Permission denied") in retrieving the default committer identity:
touch /etc/mailname; # as root
chmod -r /etc/mailname; # as root
git commit -m 'test commit'
