gitweb terminates and shows no project list, if it can not access a
sub-directory in the project root directory while looking for projects
to show.
Work it around by skipping unreadable directories.

"git commit" when seeing an totally empty message said "you did not

The check for whether the template given to 'git commit' is untouched
is done before the empty message check. This results in a wrong error
message being displayed in the following case. When the user removes
everything in template completely to abort the commit he is shown the
"template untouched" error which is wrong. He should be shown the
"empty message" error.
Do the empty message check before checking for an untouched template
thus fixing this issue.

Many uses of comparision callback function the hashmap API uses
cast the callback function type when registering it to
hashmap_init(), which defeats the compile time type checking when
the callback interface changes (e.g. gaining more parameters).
The callback implementations have been updated to take "void *"
pointers and cast them to the type they expect instead.

With the new field that is passed to the compare function, we can pass

When doing a reflog walk, we use the commit's date to
do any date limiting. In earlier versions of Git, this could
lead to nonsense results, since a skipped commit would
truncate the traversal. So a sequence like:
git commit ...
git checkout week-old-branch
git checkout -
git log -g --since=1.day.ago
would stop at the week-old-branch, even though the "git
commit" entry further back is still interesting.
As of the prior commit, which uses a parent-less traversal
of the reflog, you get the whole reflog minus any commits
whose dates do not match the specified options. This is
arguably useful, as you could scan the reflogs for commits
that originated in a certain range.
But more likely a user doing a reflog walk wants to limit
based on the reflog entries themselves. You can simulate
--until with:
git log -g @{1.day.ago}
but there's no way to ask Git to traverse only back to a
certain date. E.g.:
# show me reflog entries from the past day
git log -g --since=1.day.ago
This patch teaches the revision machinery to prefer the
reflog entry dates to the commit dates when doing a reflog
walk. Technically this is a change in behavior that affects
plumbing, but the previous behavior was so buggy that it's
unlikely anyone was relying on it.

The reflog-walk system works by putting a ref's tip into the
pending queue, and then "traversing" the reflog by
pretending that the parent of each commit is the previous
reflog entry.
This causes a number of user-visible oddities, as documented
in t1414 (and the commit message which introduced it). We
can fix all of them in one go by replacing the fake-reflog
system with a much simpler one: just keeping a list of
reflogs to show, and walking through them entry by entry.
The implementation is fairly straight-forward, but there are
a few items to note:
1. We obviously must skip calling add_parents_to_list()
when we are traversing reflogs, since we do not want to
walk the original parents at all. As a result, we must call
try_to_simplify_commit() ourselves.
There are other parts of add_parents_to_list() we skip,
as well, but none of them should matter for a reflog
traversal:
- We do not allow UNINTERESTING commits, nor
symmetric ranges (and we bail when these are used
with "-g").
- Using --source makes no sense, since we aren't
traversing. The reflog selector shows the same
information with more detail.
- Using --first-parent is still sensible, since you
may want to see the first-parent diff for each
entry. But since we're not traversing, we don't
need to cull the parent list here.
2. Since we now just walk the reflog entries themselves,
rather than starting with the ref tip, we now look at
the "new" field of each entry rather than the "old"
(i.e., we are showing entries, not faking parents).
This removes all of the tricky logic around skipping
past root commits.
But note that we have no way to show an entry with the
null sha1 in its "new" field (because such a commit
obviously does not exist). Normally this would not
happen, since we delete reflogs along with refs, but
there is one special case. When we rename the currently
checked out branch, we write two reflog entries into
the HEAD log: one where the commit goes away, and
another where it comes back.
Prior to this commit, we show both entries with
identical reflog messages. After this commit, we show
only the "comes back" entry. See the update in t3200
which demonstrates this.
Arguably either is fine, as the whole double-entry
thing is a bit hacky in the first place. And until a
recent fix, we truncated the traversal in such a case
anyway, which was _definitely_ wrong.
3. We show individual reflogs in order, but choose which
reflog to show at each stage based on which has the
most recent timestamp. This interleaves the output
from multiple reflogs based on date order, which is
probably what you'd want with limiting like "-n 30".
Note that the implementation aims for simplicity. It
does a linear walk over the reflog queue for each
commit it pulls, which may perform badly if you
interleave an enormous number of reflogs. That seems
like an unlikely use case; if we did want to handle it,
we could probably keep a priority queue of reflogs,
ordered by the timestamp of their current tip entry.

When git-rev-list sees no pending commits, it shows a usage
message. This works even when reflog-walking is requested,
because the reflog-walk code currently puts the reflog tips
into the pending queue.
In preparation for refactoring the reflog-walk code, let's
explicitly check whether we have any reflogs to walk. For
now this is a noop, but the existing reflog tests will make
sure that it kicks in after the refactoring. Likewise, we'll
add a test that "rev-list -g" without specifying any reflogs
continues to fail (so that we know our check does not kick
in too aggressively).
Note that the implementation needs to go into its own
sub-function, as the walk code does not expose its innards
outside of reflog-walk.c.

The get_revision_1() function tries to avoid entering its
main loop at all when there are no commits to look at. But
it's perfectly safe to call pop_commit() on an empty list
(in which case it will return NULL). Switching to an early
return from the loop lets us skip repeating the loop
condition before we enter the do-while. That will get more
important when we start pulling reflog-walk commits from a
source besides the revs->commits queue, as that condition
will get much more complicated.

When we're doing a reflog walk (instead of walking the
actual parent pointers), we may see commits multiple times.
For this reason, we hold on to the commit buffer for each
commit rather than freeing it after we've showed the commit.
We should do the same for the parent list. Right now this is
just a minor optimization. But once we refactor how reflog
walks are performed, keeping the parents will avoid
confusing us the second time we see the commit.

When we're walking reflogs, we leave the commit buffer and
parents in place. A comment explains that this is due to
"cycles". But the interesting thing is the unsaid
implication: that the cycles (plus our clearing of the SEEN
flag) will cause us to show commits multiple times. Let's
spell it out.

The reflog-walk code doesn't work with limit_list(). That
function traverses down the real history graph, not the fake
reflog history that get_revision() returns. So it's not
going to actually examine all of the commits we're going to
show, because we'd add them to the pending list only during
the actual traversal.
In practice this limitation doesn't really matter, because
the options that require list-limiting generally need
UNINTERESTING endpoints or symmetric ranges, which already
are forbidden for reflog walks. Still, there are likely some
corner cases that would behave oddly. We're better off to
warn the user that we can't fulfill their request than to
generate potentially wrong output.
This will also make it easier to refactor the reflog-walking
code, because it eliminates a whole area of corner cases
we'd have to consider (that already don't work anyway).

Since its inception, the general strategy of the reflog-walk
code has been to start with the tip commit for the ref, and
as we traverse replace each commit's parent pointers with
fake parents pointing to the previous reflog entry.
This lets us traverse the reflog as if it were a real
history, but it has some user-visible oddities. Namely:
1. The fake parents are used for commit selection and
display. So for example, "--merges" or "--no-merges"
are not useful, because the history appears as a linear
string of commits. Likewise, pathspec limiting is based
on the diff between adjacent entries, not the changes
actually introduced by a commit.
These are often the same (e.g., because the entry was
just running "git commit" and the adjacent entry _is_
the true parent), but it may not be in several common
cases. For instance, using "git reset" to jump around
history, or "git checkout" to move HEAD.
2. We reverse-map each commit back to its reflog. So when
it comes time to show commit X, we say "a-ha, we added
X because it was at the tip of the 'foo' reflog, so
let's show the foo reflog". But this leads to nonsense
results when you ask to traverse multiple reflogs: if
two reflogs have the same tip commit, we only map back
to one of them. Instead, we should show both.
3. If the tip of the reflog and the ref tip disagree on
the current value, we show the ref tip but give no
indication of the value in the reflog. This situation
isn't supposed to happen (since any ref update should
touch the reflog). But if it does, given that the
requested operation is to show the reflog, it makes
sense to prefer that.
This commit adds a new script with several expect_failure
tests to demonstrate the problems. This could be part of
the existing t1411, but it's a bit easier to start from a
fresh state, where we know exactly what will be in the log.
Since the new multiple-reflog tests are checking the actual
output, we can drop the "make sure we don't segfault" tests
from t1411, which are a strict subset of what we're doing
here.

Some `clean` / `smudge` filters may require a significant amount of
time to process a single blob (e.g. the Git LFS smudge filter might
perform network requests). During this process the Git checkout
operation is blocked and Git needs to wait until the filter is done to
continue with the checkout.
Teach the filter process protocol, introduced in edcc8581 ("convert: add
filter.<driver>.process option", 2016-10-16), to accept the status
"delayed" as response to a filter request. Upon this response Git
continues with the checkout operation. After the checkout operation Git
calls "finish_delayed_checkout" which queries the filter for remaining
blobs. If the filter is still working on the completion, then the filter
is expected to block. If the filter has completed all remaining blobs
then an empty response is expected.
Git has a multiple code paths that checkout a blob. Support delayed
checkouts only in `clone` (in unpack-trees.c) and `checkout` operations
for now. The optimization is most effective in these code paths as all
files of the tree are processed.

"rot13-filter.pl" always writes "OUT <size>" to the debug log at the end
of a response.
This works perfectly for the existing responses "abort", "error", and
"success". A new response "delayed", that will be introduced in a
subsequent patch, accepts the input without giving the filtered result
right away. At this point we cannot know the size of the response.
Therefore, we do not write "OUT <size>" for "delayed" responses.
To simplify the code we do not write "OUT <size>" for "abort" and
"error" responses either as their size is always zero.

When running gpg-relevant tests, a gpg-daemon is spawned for each
GNUPGHOME used. This daemon may stay running after the test and cache
file descriptors for the trash directories, even after the trash
directory is removed. This leads to ENOENT errors when attempting to
create files if tests are run multiple times.
Add a cleanup script to force flushing the gpg-agent for that GNUPGHOME
(if any) before setting up the GPG relevant-environment.

If done_pbase_paths is NULL then done_pbase_paths_num must be zero and
done_pbase_path_pos() returns -1 without accessing the array, so the
check is not necessary.
If the invariant was violated then the check would make sure we keep
on going and allocate the necessary amount of memory in the next
ALLOC_GROW call. That sounds nice, but all array entries except for
one would contain garbage data.
If the invariant was violated without the check we'd get a segfault in
done_pbase_path_pos(), i.e. an observable crash, alerting us of the
presence of a bug.
Currently there is no such bug: Only the functions check_pbase_path()
and cleanup_preferred_base() change pointer and counter, and both make
sure to keep them in sync. Get rid of the check anyway to allow us to
see if later changes introduce such a defect, and to simplify the code.

If obj->type == OBJ_TREE, an invocation of fsck_walk() will invoke
parse_tree() and return quickly if that returns nonzero, so it is of no
use for traverse_one_object() to invoke parse_tree() in this situation
before invoking fsck_walk(). Remove that code.
The behavior of traverse_one_object() is changed slightly in that it now
returns -1 instead of 1 in the case that parse_tree() fails, but this is
not an issue because its only caller (traverse_reachable) does not care
about the value as long as it is nonzero.
This code was introduced in commit 271b8d2 ("builtin-fsck: move away
from object-refs to fsck_walk", 2008-02-25). The same issue existed in
that commit.

Back when the modern http_options() codepath was created to parse
various http.* options at 29508e1e ("Isolate shared HTTP request
functionality", 2005-11-18), and then later was corrected for
interation between the multiple configuration files in 7059cd99
("http_init(): Fix config file parsing", 2009-03-09), we parsed
configuration variables like http.sslkey, http.sslcert as plain
vanilla strings, because git_config_pathname() that understands
"~[username]/" prefix did not exist. Later, we converted some of
them (namely, http.sslCAPath and http.sslCAInfo) to use the
function, and added variables like http.cookeyFile http.pinnedpubkey
to use the function from the beginning. Because of that, these
variables all understand "~[username]/" prefix.
Make the remaining two variables, http.sslcert and http.sslkey, also
aware of the convention, as they are both clearly pathnames to
files.

This is another test balloon to see if we get complaints from people
whose compilers do not support designated initializer for arrays.
The use of the feature is not all that interesting for cases like
the one this patch touches, where the initialized elements of the
array is dense, but it would be nice if we can use the feature to
initialize an array that has elements initialized to interesting
values only sparsely.

There are certain C99 features that might be nice to use in
our code base, but we've hesitated to do so in order to
avoid breaking compatibility with older compilers. But we
don't actually know if people are even using pre-C99
compilers these days.
One way to figure that out is to introduce a very small use
of a feature, and see if anybody complains. The strbuf code
is a good place to do this for a few reasons:
- it always gets compiled, no matter which Makefile knobs
have been tweaked.
- it's very stable; this definition hasn't changed in a
long time and is not likely to (so if we have to revert,
it's unlikely to cause headaches)
If this patch can survive a few releases without complaint,
then we can feel more confident that designated initializers
are widely supported by our user base. It also is an
indication that other C99 features may be supported, but not
a guarantee (e.g., gcc had designated initializers before
C99 existed).
And if we do get complaints, then we'll have gained some
data and we can easily revert this patch.

"%C(color name)" in the pretty print format always produced ANSI
color escape codes, which was an early design mistake. They now
honor the configuration (e.g. "color.ui = never") and also tty-ness
of the output medium.

When color placeholders like %(color:red) are used in a
ref-filter format, we unconditionally output the colors,
even if the user has asked us for no colors. This usually
isn't a problem when the user is constructing a --format on
the command line, but it means we may do the wrong thing
when the format is fed from a script or alias. For example:
$ git config alias.b 'branch --format=%(color:green)%(refname)'
$ git b --no-color
should probably omit the green color. Likewise, running:
$ git b >branches
should probably also omit the color, just as we would for
all baked-in coloring (and as we recently started to do for
user-specified colors in --pretty formats).
This commit makes both of those cases work by teaching
the ref-filter code to consult want_color() before
outputting any color. The color flag in ref_format defaults
to "-1", which means we'll consult color.ui, which in turn
defaults to the usual isatty() check on stdout. However,
callers like git-branch which support their own color config
(and command-line options) can override that.
The new tests independently cover all three of the callers
of ref-filter (for-each-ref, tag, and branch). Even though
these seem redundant, it confirms that we've correctly
plumbed through all of the necessary config to make colors
work by default.

The color placeholders have traditionally been
unconditional, showing colors even when git is not otherwise
configured to do so. This was not so bad for their original
use, which was on the command-line (and the user could
decide at that moment whether to add colors or not). But
these days we have configured formats via pretty.*, and
those should operate correctly in multiple contexts.
In 3082517 (log --format: teach %C(auto,black) to respect
color config, 2012-12-17), we gave an extended placeholder
that could be used to accomplish this. But it's rather
clunky to use, because you have to specify it individually
for each color (and their matching resets) in the format.
We shied away from just switching the default to auto,
because it is technically breaking backwards compatibility.
However, there's not really a use case for unconditional
colors. The most plausible reason you would want them is to
redirect "git log" output to a file. But there, the right
answer is --color=always, as it does the right thing both
with custom user-format colors and git-generated colors.
So let's switch to the more useful default. In the
off-chance that somebody really does find a use for
unconditional colors without wanting to enable the rest of
git's colors, we provide a new %C(always,...) to enable the
old behavior. And we can remind them of --color=always in
the documentation.

When rev-list pretty-prints a commit, it creates a new
pretty_print_context and copies items from the rev_info
struct. We don't currently copy the "use_color" field,
though. Nobody seems to have noticed because the only part
of pretty.c that cares is the %C(auto,...) placeholder, and
presumably not many people use that with the rev-list
plumbing (as opposed to with git-log).
It will become more noticeable in a future patch, though,
when we start treating all user-format colors as auto-colors
(in which case it would become impossible to format colors
with rev-list, even with --color=always).

In most commands we load config before parsing command line
options, since it lets the latter override the former with a
simple variable assignment. In the case of for-each-ref,
though, we do it in the reverse order. This is OK with
the current code, since there's no interaction between the
config and command-line options.
However, as the ref-filter code starts to care about config
during verify_ref_format(), we'll want to make sure the
config is loaded. Let's bump the config to the usual spot
near the top of the function.
We can drop the comment there; it's impossible to keep a
"why we load the config" comment like this up to date with
every config option we might be interested in. And indeed,
it's already stale; we'd care about core.abbrev, for
instance, when %(objectname:short) is used.
