show-externals can be used by scripts to provide svn:externals-like
functionality. For example, a script can list all of the externals and then
use check out the listed URLs at the appropriate paths, similar to what the svn
client does. Said script (or perhaps git-svn itself, in the future) could
simply invoke svn export on the paths, or it could go one further, using
git-svn clone and even git-submodule together to better integrate externals
checkouts.
The implementation is shamelessly copied from show-ignores. A more general
command to list user-specified properties is probably a better idea.

Well, after thinking about this a bit, I think there's a solution that may
work well with the current thing too: instead of looping just *once* over
the list of rename pairs, loop twice - and simply refuse to do copies on
the first loop.
This trivial patch does that, and turns Kumar's test-case into a perfect
rename list.
It's not pretty, it's not smart, but it seems to work. There's something
to be said for keeping it simple and stupid.
And it should not be nearly as expensive as it may _look_. Yes, the loop
is "(i = 0; i < num_create * num_src; i++)", but the important part is
that the whole array is sorted by rename score, and we have a
if (mx[i].score < minimum_score)
break;
in it, so uthe loop actually would tend to terminate rather quickly.
Anyway, Kumar, the thing to take away from this is:
- git really doesn't even *care* about the whole "rename detection"
internally, and any commits you have done with renames are totally
independent of the heuristics we then use to *show* the renames.
- the rename detection really is for just two reasons: (a) keep humans
happy, and keep the diffs small and (b) help automatic merging across
renames. So getting renames right is certainly good, but it's more of a
"politeness" issue than a "correctness" issue, although the merge
portion of it does matter a lot sometimes.
- the important thing here is that you can commit your changes and not
worry about them being somehow "corrupted" by lack of rename detection,
even if you commit them with a version of git that doesn't do rename
detection the way you expected it. The rename detection is an
"after-the-fact" thing, not something that actually gets saved in the
repository, which is why we can change the heuristics _after_ seeing
examples, and the examples magically correct themselves!
- try out the two patches I've posted, and see if they work for you. They
pass the test-suite, and the output for your example commit looks sane,
but hey, if you have other test-cases, try them out.

Kumar Gala had a case in the u-boot archive with multiple renames of files
with identical contents, and git would turn those into multiple "copy"
operations of one of the sources, and just deleting the other sources.
This patch makes the git exact rename detection prefer to spread out the
renames over the multiple sources, rather than do multiple copies of one
source.
NOTE! The changes are a bit larger than required, because I also renamed
the variables named "one" and "two" to "target" and "source" respectively.
That makes the logic easier to follow, especially as the "one" was
illogically the target and not the soruce, for purely historical reasons
(this piece of code used to traverse over sources and targets in the wrong
order, and when we fixed that, we didn't fix the names back then. So I
fixed them now).
The important part of this change is just the trivial score calculations
for when files have identical contents:
/* Give higher scores to sources that haven't been used already */
score = !source->rename_used;
score += basename_same(source, target);
and when we have multiple choices we'll now pick the choice that gets the
best rename score, rather than only looking at whether the basename
matched.
It's worth noting a few gotchas:
- this scoring is currently only done for the "exact match" case.
In particular, in Kumar's example, even after this patch, the inexact
match case is still done as a copy+delete rather than as two renames:
delete mode 100644 board/cds/mpc8555cds/u-boot.lds
copy board/{cds => freescale}/mpc8541cds/u-boot.lds (97%)
rename board/{cds/mpc8541cds => freescale/mpc8555cds}/u-boot.lds (97%)
because apparently the "cds/mpc8541cds/u-boot.lds" copy looked
a bit more similar to both end results. That said, I *suspect* we just
have the exact same issue there - the similarity analysis just gave
identical (or at least very _close_ to identical) similarity points,
and we do not have any logic to prefer multiple renames over a
copy/delete there.
That is a separate patch.
- When you have identical contents and identical basenames, the actual
entry that is chosen is still picked fairly "at random" for the first
one (but the subsequent ones will prefer entries that haven't already
been used).
It's not actually really random, in that it actually depends on the
relative alphabetical order of the files (which in turn will have
impacted the order that the entries got hashed!), so it gives
consistent results that can be explained. But I wanted to point it out
as an issue for when anybody actually does cross-renames.
In Kumar's case the choice is the right one (and for a single normal
directory rename it should always be, since the relative alphabetical
sorting of the files will be identical), and we now get:
rename board/{cds => freescale}/mpc8541cds/init.S (100%)
rename board/{cds => freescale}/mpc8548cds/init.S (100%)
which is the "expected" answer. However, it might still be better to
change the pedantic "exact same basename" on/off choice into a more
graduated "how similar are the pathnames" scoring situation, in order
to be more likely to get the exact rename choice that people *expect*
to see, rather than other alternatives that may *technically* be
equally good, but are surprising to a human.
It's also unclear whether we should consider "basenames are equal" or
"have already used this as a source" to be more important. This gives them
equal weight, but I suspect we might want to just multiple the "basenames
are equal" weight by two, or something, to prefer equal basenames even if
that causes a copy/delete pair. I dunno.
Anyway, what I'm just saying in a really long-winded manner is that I
think this is right as-is, but it's not the complete solution, and it may
want some further tweaking in the future.

Earlier, 'git prune' would prune all loose unreachable objects.
This could be quite dangerous, as the objects could be used in
an ongoing operation.
This patch adds a mode to expire only loose, unreachable objects
which are older than a certain time. For example, by
git prune --expire 14.days
you can prune only those objects which are loose, unreachable
and older than 14 days (and thus probably outdated).
The implementation uses st.st_mtime rather than st.st_ctime,
because it can be tested better, using 'touch -d <time>' (and
omitting the test when the platform does not support that
command line switch).

There were two problems:
1. We only look at the config variable if there is no module
given on the command line. We checked this by comparing
@ARGV == 0. However, at the time of the comparison, we
have not yet parsed the dashed options, meaning that
"git cvsimport" would read the variable but "git
cvsimport -a" would not. This is fixed by simply moving
the check after the call to getopt.
2. If the config variable did not exist, we were adding an
empty string to @ARGV. The rest of the script, rather
than barfing for insufficient input, would then try to
import the module '', leading to rather confusing error
messages. Based on patch from Emanuele Giaquinta.

Occasionally, in some setups (*cough* forks on repo.or.cz *cough*) some
refs go stale, e.g. when the forkee rebased and lost some objects needed
by the fork. The quick & dirty way to deal with those refs is to delete
them and push them again.
However, git-push first would first fetch the current commit name for the
ref, would receive a null sha1 since the ref does not point to a valid
object, then tell receive-pack that it should delete the ref with this
commit name. delete_ref() would be subsequently be called, and check that
resolve_ref() (which does _not_ check for validity of the object) returns
the same commit name. Which would fail.
The proper fix is to avoid corrupting repositories, but in the meantime
this is a good fix in any case.
Incidentally, some instances of "cd .." in the test cases were fixed, so
that subsequent test cases run in t/trash/ irrespective of the outcome of
the previous test cases.

The user interface provided by the command loop in git-add--interactive
gives the impression that subcommands can only be launched by entering
an integer identifier from 1 through 8.
A "hidden" feature is that any string can be entered, and a regex search
anchored at the beginning of the string is used to find the uniquely
matching option.
This patch makes this feature a little more obvious by highlighting the
first character of each subcommand (for example "patch" is displayed as
"[p]atch").
A new function is added to detect the shortest unique prefix and this
is used to decide what to highlight. Highlighting is also applied when
choosing files.
In the case where the common prefix may be unreasonably large
highlighting is omitted; in this patch the soft limit (above which the
highlighting will be omitted for a particular item) is 0 (in other words,
there is no soft limit) and the hard limit (above which highlighting will
be omitted for all items) is 3, but this can be tweaked.
The actual highlighting is done by the highlight_prefix function, which
will enable us to implement ANSI color code-based highlighting (most
likely using underline or boldface) in the future.

Operations that walk directories or trees, which potentially need to
consult the .gitignore files, used to always try to open the .gitignore
file every time they entered a new directory, even when they ended up
not needing to call excluded() function to see if a path in the
directory is ignored. This was done by push/pop exclude_per_directory()
functions that managed the data in a stack.
This changes the directory walking API to remove the need to call these
two functions. Instead, the directory walk data structure caches the
data used by excluded() function the last time, and lazily reuses it as
much as possible. Among the data the last check used, the ones from
deeper directories that the path we are checking is outside are
discarded, data from the common leading directories are reused, and then
the directories between the common directory and the directory the path
being checked is in are checked for .gitignore file. This is very
similar to the way gitattributes are handled.
This API change also fixes "ls-files -c -i", which called excluded()
without setting up the gitignore data via the old push/pop functions.

When calling 'git pull' with the '--rebase' option, it performs a
fetch + rebase instead of a fetch + merge.
This behavior is more desirable than fetch + pull when a topic branch
is ready to be submitted and needs to be update.
fetch + rebase might also be considered a better workflow with shared
repositories in any case, or for contributors to a centrally managed
repository, such as WINE's.
As a convenience, you can set the default behavior for a branch by
defining the config variable branch.<name>.rebase, which is
interpreted as a bool. This setting can be overridden on the command
line by --rebase and --no-rebase.
