Two more tests that sleep only to waste tick can be converted to use
test_tick and take expiry parameters relative to $test_tick. The basic
idea is to replace "sleep 1" with "test_tick" to cause the "time" to pass.
These tests are interested in expiring things with "now" as the timestamp,
soo use a timestamp relative to $test_tick to give them more stability and
reproducibility.
3cb22b8 (Per-ref reflog expiry configuration, 2008-06-15) added support
for setting the expiry parameters differently for different reflog, but
it was never documented.
The option tells the command to expire older reflog entries that refer to
commits that are no longer reachable from the tip of the ref the reflog is
associated with. To avoid repeated merge_base() invocations, we used to
mark commits that are known to be reachable by walking the history from
the tip until we hit commits that are older than expire-total (which is
the timestamp before which all the reflog entries are expired).
However, it is a different matter if a commit is _not_ known to be
reachable and the commit is known to be unreachable. Because you can
rewind a ref to an ancient commit and then reset it back to the original
tip, a recent reflog entry can point at a commit that older than the
expire-total timestamp and we shouldn't expire it. For that reason, we
had to run merge-base computation when a commit is _not_ known to be
reachable.
This introduces a lazy/on-demand traversal of the history to mark
reachable commits in steps. As before, we mark commits that are newer
than expire-total to optimize the normal case before walking reflog, but
we dig deeper from the commits the initial step left off when we encounter
a commit that is not known to be reachable.
git svn: branch/tag commands detect username in URLs
svn+ssh:// repositories often have userinfo embedded in the URL
which were stripped out of the "git-svn-id:" trailers. Since
the SVN::Client::copy function takes userinfo into account when
matching URLs for SVN repositories, we need to retrieve the full
URL with embedded userinfo in it to avoid mismatched URLs.

worktree: don't segfault with an absolute pathspec without a work tree
ignore unknown color configuration
help.autocorrect: do not run a command if the command given is junk
Illustrate "filter" attribute with an example
worktree: don't segfault with an absolute pathspec without a work tree
If a command is run with an absolute path as a pathspec inside a bare
repository, e.g. "rev-list HEAD -- /home", the code tried to run strlen()
on NULL, which is the result of get_git_work_tree(), and segfaulted. It
should just fail instead.
Currently the function returns NULL even inside .git/ in a repository
with a work tree, but that is a separate issue.
When parsing the config file, if there is a value that is
syntactically correct but unused, we generally ignore it.
This lets non-core porcelains store arbitrary information in
the config file, and it means that configuration files can
be shared between new and old versions of git (the old
versions might simply ignore certain configuration).
The one exception to this is color configuration; if we
encounter a color.{diff,branch,status}.$slot variable, we
die if it is not one of the recognized slots (presumably as
a safety valve for user misconfiguration). This behavior
has existed since 801235c (diff --color: use
$GIT_DIR/config, 2006-06-24), but hasn't yet caused a
problem. No porcelain has wanted to store extra colors, and
we once a color area (like color.diff) has been introduced,
we've never changed the set of color slots.
However, that changed recently with the addition of
color.diff.func. Now a user with color.diff.func in their
config can no longer freely switch between v1.6.6 and older
versions; the old versions will complain about the existence
of the variable.
This patch loosens the check to match the rest of
git-config; unknown color slots are simply ignored. This
doesn't fix this particular problem, as the older version
(without this patch) is the problem, but it at least
prevents it from happening again in the future.

This was because the code reordered (when one was given) or added (when

making it to "archive HEAD -- path --format=zip", i.e. an extra pathspec

They caused a "git pull" (without any arguments, and without any local
commits---only to update to the other side) to warn that commit log
message is ignored because the merge resulted in a fast-forward.
Another possible solution is to add an extra option to "git merge" so that
"git pull" can tell it that the message given is not coming from the end
user (the canned message is passed just in case the merge resulted in a
non-ff and caused commit), but I think it is easier _not_ to deprecate the
old syntax.
Commit 24ab81a fixed the deletion of empty files, but broke
deletion of non-empty files. The approach it took was to
factor out the "deleted" line from the patch header into its
own hunk, the same way we do for mode changes. However,
unlike mode changes, we only showed the special "delete this
file" hunk if there were no other hunks. Otherwise, the user
would annoyingly be presented with _two_ hunks: one for
deleting the file and one for deleting the content.
This meant that in the non-empty case, we forgot about the
deleted line entirely, and we submitted a bogus patch to
git-apply (with "/dev/null" as the destination file, but not
marked as a deletion).
Instead, this patch combines the file deletion hunk and the
content deletion hunk (if there is one) into a single
deletion hunk which is either staged or not.

git-gui: Increase blame viewer usability on MacOS.
On MacOS raising a window causes the focus to be transferred
to it -- although it may actually be a bug in the Tcl/Tk port.
When this happens with the blame viewer tooltips, it makes
the interface less usable, because Entry and Leave handlers
on the text view cause the tip to disappear once the mouse
is moved even 1 pixel.
This commit makes the code raise the main window on MacOS
when Tk 8.5 is used. This version seems to properly support
wm transient by making the tip stay on top of the master,
so reraising the master does not cause it to disappear. Thus
the only remaining sign of problems is slight UI flicker
when focus is momentarily transferred to the tip and back.

git-gui: search 4 directories to improve statistic of gc hint
On Windows, git-gui suggests running the garbage collector if it finds
1 or more files in .git/objects/42 (as opposed to 8 files on other
platforms). The probability of that happening if the repo contains
about 100 loose objects is 32%. The probability for the same to happen
when searching 4 directories is only 8%, which is bit more reasonable.
Also remove $objects_limit from the message, because we already know
that we are above (or close to) that limit. Telling the user about
that number does not really give him any useful information.
The following octave script shows the probability for at least m*q
objects to be found in q subdirectories of .git/objects if n is the
total number of objects.
q = 4;
m = [1 2 8];
n = 0:10:2000;
P = zeros(length(n), length(m));
for k = 1:length(n)
P(k, :) = 1-binocdf(q*m-1, n(k), q/(256-q));
end
plot(n, P);
Fix diff -B/--dirstat miscounting of newly added contents
What used to happen is that diffcore_count_changes() simply ignored any
hashes in the destination that didn't match hashes in the source. EXCEPT
if the source hash didn't exist at all, in which case it would count _one_
destination hash that happened to have the "next" hash value. As a
consequence, newly added material was often undercounted, making output
from --dirstat and "complete rewrite" detection used by -B unrelialble.
This changes it so that:
- whenever it bypasses a destination hash (because it doesn't match a
source), it counts the bytes associated with that as "literal added"
- at the end (once we have used up all the source hashes), we do the same
thing with the remaining destination hashes.
- when hashes do match, and we use the difference in counts as a value,
we also use up that destination hash entry (the 'd++').

Documentation: xmlto 0.0.18 does not know --stringparam
Newer DocBook stylesheets want man.base.url.for.relative.links
parameter set when formatting manpages with external references
to turn them into full URLs, and leave a helpful "you should
set this parameter" message in the output. Earlier we added
the MAN_BASE_URL make variable to specify the value for it.
When MAN_BASE_URL is not given, it ought to be safe to set the
parameter to empty; it would result in an empty leading path for
older stylesheets that ignore the parameter, and newer ones
would produce the same "relative URL" without the message.
Unfortunately, older xmlto (at least version 0.0.18 released in
early 2004 that comes with RHEL/CentOS 5) does not understand
the --stringparam command line option, so we cannot add the
parameter definition unconditionally to the command line. Work
it around by passing the parameter only when set.
If you do not have a suitable URL prefix, you can pass a quoted empty
string to it, like so:
