sequencer: fix missing newline
|
|
When using rebase --interactive where one of the lines is marked as
'edit' this is the resulting output:
Stopped at ec3b9c4... stuffYou can amend the commit now, with
git commit --amend
Once you are satisfied with your changes, run
git rebase --continue
A newline character is missing at the end of the "Stopped at ..." line and
before the "You can amend ..." line. This patch fixes the malformed output by
adding the missing newline character to the end of the "Stopped at ..." line.

Change the documentation for push.tracking=* to re-include a mention
of what "tracking" does.
The "tracking" option was renamed to "upstream" back in
53c4031 ("push.default: Rename 'tracking' to 'upstream'", 2011-02-16),
this section was then subsequently rewritten in 87a70e4 ("config doc:
rewrite push.default section", 2013-06-19) to remove any mention of
"tracking".
Maybe we should just warn or die nowadays if this option is in the
config, but I had some old config of mine use this option, I'd
forgotten that it was a synonym, and nothing in git's documentation
mentioned that.
That's bad, either we shouldn't support it at all, or we should
document what it does. This patch does the latter.

"git add -p <pathspec>" unnecessarily expanded the pathspec to a
list of individual files that matches the pathspec by running "git
ls-files <pathspec>", before feeding it to "git diff-index" to see

language supported by "diff-index" was weaker. These days they are

Make git-credential-cache follow the XDG base path specification by
default. This increases consistency with other applications and helps
keep clutter out of users' home directories.
Check the old socket location, ~/.git-credential-cache/, and use
~/.git-credential-cache/socket if that directory exists rather than
forcing users who have used `git credential-cache` before to migrate to
the new XDG compliant location.
Otherwise use the socket $XDG_CACHE_HOME/git/credential/socket following
XDG base path specification. Use the subdirectory credential/ in case
other files are cached under $XDG_CACHE_HOME/git/ in the future and to
make the socket's purpose clear.

The final() function accepts a NULL value for certain
parameters, and falls back to writing into a reusable "name"
buffer, and then either:
1. For "keep_name", requiring all uses to do "keep_name ?
keep_name : name.buf". This is awkward, and it's easy
to accidentally look at the maybe-NULL keep_name.
2. For "final_index_name" and "final_pack_name", aliasing
those pointers to the "name" buffer. This is easier to
use, but the aliased pointers become invalid after the
buffer is reused (this isn't a bug now, but it's a
potential pitfall).
One way to make this safer would be to introduce an extra
pointer to do the aliasing, and have its lifetime match the
validity of the "name" buffer. But it's still easy to
accidentally use the wrong name (i.e., to use
"final_pack_name" instead of the aliased pointer).
Instead, let's use three separate buffers that will remain
valid through the function. That makes it safe to alias the
pointers and use them consistently. The extra allocations
shouldn't matter, as this function is not performance
sensitive.

In several places we write the name of the pack filename
into a fixed-size buffer using snprintf(), but do not check
the return value. As a result, a very long object directory
could cause us to quietly truncate the pack filename
(potentially leading to a corrupted repository, as a newly
written packfile could be missing its .pack extension).
We can use odb_pack_name() to do this with a strbuf (and
shorten the code, as well).

The odb_pack_keep() function generates the name of a .keep
file and opens it. This has two problems:
1. It requires a fixed-size buffer to create the filename
and doesn't notice when the result is truncated.
2. Of the two callers, one sometimes wants to open a
filename it already has, which makes things awkward (it
has to do so manually, and skips the leading-directory
creation).
Instead, let's have odb_pack_keep() just open the file.
Generating the name isn't hard, and a future patch will
switch callers over to odb_pack_name() anyway.

We provide sha1_pack_name() and sha1_pack_index_name(), but
the more generic form (which takes its own strbuf and an
arbitrary extension) is only used to implement the other
two. Let's make it available, but clean up a few things:
1. Name it odb_pack_name(), as the original
sha1_get_pack_name() is long but not all that
descriptive.
2. Switch the strbuf argument to the beginning, so that it
matches similar path-building functions like
git_path_buf().
3. Clean up the out-dated docstring and move it to the

All of these options do the same thing "--foo" iterates over
the "foo" refs, and "--foo=<glob>" does the same with a
glob. We can factor this into its own function to avoid
repeating ourselves.
There are two subtleties to note:
- the original called for_each_branch_ref(), etc, in the
non-glob case. Now we will call for_each_ref_in("refs/heads/")
which is exactly what for_each_branch_ref() did under
the hood.
- for --glob, we'll call for_each_glob_ref_in() with a
NULL "prefix" argument. Which is exactly what
for_each_glob_ref() was doing already.
So both cases should behave identically, and it seems
reasonable to assume that this will remain the same. The
functions we are calling now are the more-generic ones, and
the ones we are dropping are just convenience wrappers.

We can't just use a bare skip_prefix() for these cases,
because we need to match both the "--foo" form and the
"--foo=<value>" form (and tell the difference between the
two in the caller).
We can wrap this in a simple helper which has two obvious
callsites, and will gain some more in the next patch.
Note that the error output for abbrev-ref changes slightly,
as we don't keep our original "arg" pointer. However, the
new output should hopefully be more clear:
[before]
fatal: unknown mode for --abbrev-ref=foo
[after]
fatal: unknown mode for --abbrev-ref: foo

Worse, the value "0" is indistinguishable from the unset

Many developers use functionality in their editors that allows for quick
syntax checks, including warning about questionable constructs. This
functionality allows rapid development with fewer errors. However, such
functionality generally does not allow the specification of
project-specific defines or command-line options.
Since the SHA1_HEADER include is not defined in such a case,
developers see spurious errors when using these tools. Furthermore,
there are known implementations of "cc" whose '#include' is unhappy
with this construct.
Instead of using SHA1_HEADER, create a hash.h header and use #if
and #elif to select the desired header. Have the Makefile pass an
appropriate option to help the header select the right implementation to
use.
[jc: make BLK_SHA1 the fallback default as discussed on list,
e.g. <20170314201424.vccij5z2ortq4a4o@sigill.intra.peff.net>; also
remove SHA1_HEADER and SHA1_HEADER_SQ that are no longer used].

This function now has a new caller in addition to setup_git_directory():
the newly introduced discover_git_directory(). That function wants to
discover the current .git/ directory, and in case of a corrupted one
simply pretend that there is none to be found.
Example: if a stale .git file exists in the parent directory, and the
user calls `git -p init`, we want Git to simply *not* read any
repository config for the pager (instead of aborting with a message that
the .git file is corrupt).
Let's actually pretend that there was no GIT_DIR to be found in that case
when being called from discover_git_directory(), but keep the previous
behavior (i.e. to die()) for the setup_git_directory() case.

Earlier, we punted and simply assumed that we are in the top-level
directory of the project, and that there is no .git file but a .git/
directory so that we can read directly from .git/config.
However, that is not necessarily true. We may be in a subdirectory. Or
.git may be a gitfile. Or the environment variable GIT_DIR may be set.
To remedy this situation, we just refactored the way
setup_git_directory() discovers the .git/ directory, to make it
reusable, and more importantly, to leave all global variables and the
current working directory alone.
Let's discover the .git/ directory correctly in read_early_config() by
using that new function.
This fixes 4 known breakages in t7006.

So far, we only look whether the startup_info claims to have seen a
git_dir.
However, do_git_config_sequence() (and consequently the
git_config_with_options() call used by read_early_config() asks the
have_git_dir() function whether we have a .git/ directory, which in turn
also looks at git_dir and at the environment variable GIT_DIR. And when
this is the case, the repository config is handled already, so we do not
have to do that again explicitly.
Let's just use the same function, have_git_dir(), to determine whether we
have to handle .git/config explicitly.

We modified the setup_git_directory_gently_1() function earlier to make
it possible to discover the GIT_DIR without changing global state.
However, it is still a bit cumbersome to use if you only need to figure
out the (possibly absolute) path of the .git/ directory. Let's just
provide a convenient wrapper function with an easier signature that
*just* discovers the .git/ directory.
We will use it in a subsequent patch to fix the early config.

For historical reasons, Git searches for the .git/ directory (or the
.git file) by changing the working directory successively to the parent
directory of the current directory, until either anything was found or
until a ceiling or a mount point is hit.
Further global state may be changed in case a .git/ directory was found.
We do have a use case, though, where we would like to find the .git/
directory without having any global state touched, though: when we read
the early config e.g. for the pager or for alias expansion.
Let's just move all of code that changes any global state out of the
function `setup_git_directory_gently_1()` into
`setup_git_directory_gently()`.
In subsequent patches, we will use the _1() function in a new
`discover_git_directory()` function that we will then use for the early
config code.
Note: the new loop is a *little* tricky, as we have to handle the root
directory specially: we cannot simply strip away the last component
including the slash, as the root directory only has that slash. To remedy
that, we introduce the `min_offset` variable that holds the minimal length
of an absolute path, and using that to special-case the root directory,
including an early exit before trying to find the parent of the root
directory.

Currently, the offset parameter (indicating what part of the cwd
parameter corresponds to the current directory after discovering the
.git/ directory) is set to 0 when we are running in the root directory.
However, in the next patches we will avoid changing the current working
directory while searching for the .git/ directory, meaning that the
offset corresponding to the root directory will have to be 1 to reflect
that this directory is characterized by the path "/" (and not "").
So let's make sure that setup_discovered_git_directory() only tries to
append the trailing slash to non-root directories.
Note: the setup_bare_git_directory() does not need a corresponding
change, as it does not want to return a prefix.

When we want to get the list of modified files, we first
expand any user-provided pathspecs with "ls-files", and then
feed the resulting list of paths as arguments to
"diff-index" and "diff-files". If your pathspec expands into
a large number of paths, you may run into one of two
problems:
1. The OS may complain about the size of the argument
list, and refuse to run. For example:
$ (ulimit -s 128 && git add -p drivers)
Can't exec "git": Argument list too long at .../git-add--interactive line 177.
Died at .../git-add--interactive line 177.
That's on the linux.git repository, which has about 20K
files in the "drivers" directory (none of them modified
in this case). The "ulimit -s" trick is necessary to
show the problem on Linux even for such a gigantic set
of paths. Other operating systems have much smaller
limits (e.g., a real-world case was seen with only 5K
files on OS X).
2. Even when it does work, it's really slow. The pathspec
code is not optimized for huge numbers of paths. Here's
the same case without the ulimit:
$ time git add -p drivers
No changes.
real 0m16.559s
user 0m53.140s
sys 0m0.220s
We can improve this by skipping "ls-files" completely, and
just feeding the original pathspecs to the diff commands.
This solution was discussed in 2010:
http://public-inbox.org/git/20100105041438.GB12574@coredump.intra.peff.net/
but at the time the diff code's pathspecs were more
primitive than those used by ls-files (e.g., they did not
support globs). Making the change would have caused a
user-visible regression, so we didn't.
Since then, the pathspec code has been unified, and the diff
commands natively understand pathspecs like '*.c'.
This patch implements that solution. That skips the
argument-list limits, and the result runs much faster:
$ time git add -p drivers
No changes.
real 0m0.149s
user 0m0.116s
sys 0m0.080s
There are two new tests. The first just exercises the
globbing behavior to confirm that we are not causing a
regression there. The second checks the actual argument
behavior using GIT_TRACE. We _could_ do it with the "ulimit
-s" trick, as above. But that would mean the test could only
run where "ulimit -s" works. And tests of that sort are
expensive, because we have to come up with enough files to
actually bust the limit (we can't just shrink the "128" down
infinitely, since it is also the in-program stack size).
Finally, two caveats and possibilities for future work:
a. This fixes one argument-list expansion, but there may
be others. In fact, it's very likely that if you run
"git add -i" and select a large number of modified
files that the script would try to feed them all to a
single git command.
In practice this is probably fine. The real issue here
is that the argument list was growing with the _total_
number of files, not the number of modified or selected
files.
b. If the repository contains filenames with literal wildcard
characters (e.g., "foo*"), the original code expanded
them via "ls-files" and then fed those wildcard names
to "diff-index", which would have treated them as
wildcards. This was a bug, which is now fixed (though
unless you really go through some contortions with
":(literal)", it's likely that your original pathspec
would match whatever the accidentally-expanded wildcard
would anyway).
So this takes us one step closer to working correctly
with files whose names contain wildcard characters, but
it's likely that others remain (e.g., if "git add -i"
feeds the selected paths to "git add").

In our own .gitattributes file we have attributes such as:
*.[ch] whitespace=indent,trail,space
When querying for attributes we want to be able to ask for the exact
value, i.e.
git ls-files :(attr:whitespace=indent,trail,space)
should work, but the commas are used in the attr magic to introduce
the next attr, such that this query currently fails with
fatal: Invalid pathspec magic 'trail' in ':(attr:whitespace=indent,trail,space)'
This change allows escaping characters by a backslash, such that the query
git ls-files :(attr:whitespace=indent\,trail\,space)
will match all path that have the value "indent,trail,space" for the
whitespace attribute. To accomplish this, we need to modify two places.
First `parse_long_magic` needs to not stop early upon seeing a comma or
closing paren that is escaped. As a second step we need to remove any
escaping from the attr value.

If we parse a remote alternates (or http-alternates), we
expect relative lines like:
../../foo.git/objects
which we convert into "$URL/../foo.git/" (and then use that
as a base for fetching more objects).
But if the remote feeds us nonsense like just:
../
we will try to blindly strip the last 7 characters, assuming
they contain the string "objects". Since we don't _have_ 7
characters at all, this results in feeding a small negative
value to strbuf_add(), which converts it to a size_t,
resulting in a big positive value. This should consistently
fail (since we can't generall allocate the max size_t minus
7 bytes), so there shouldn't be any security implications.
Let's fix this by using strbuf_strip_suffix() to drop the
characters we want. If they're not present, we'll ignore the
alternate (in theory we could use it as-is, but the rest of
the http-walker code unconditionally tacks "objects/" back
on, so it is it not prepared to handle such a case).

Sometimes a set of repositories want to share configuration settings
among themselves that are distinct from other such sets of repositories.
A user may work on two projects, each of which have multiple
repositories, and use one user.email for one project while using another
for the other.
Setting $GIT_DIR/.config works, but if the penalty of forgetting to
update $GIT_DIR/.config is high (especially when you end up cloning
often), it may not be the best way to go. Having the settings in
~/.gitconfig, which would work for just one set of repositories, would
not well in such a situation. Having separate ${HOME}s may add more
problems than it solves.
Extend the include.path mechanism that lets a config file include
another config file, so that the inclusion can be done only when some
conditions hold. Then ~/.gitconfig can say "include config-project-A
only when working on project-A" for each project A the user works on.
In this patch, the only supported grouping is based on $GIT_DIR (in
absolute path), so you would need to group repositories by directory, or
something like that to take advantage of it.
We already have include.path for unconditional includes. This patch goes
with includeIf.<condition>.path to make it clearer that a condition is
required. The new config has the same backward compatibility approach as
include.path: older git versions that don't understand includeIf will
simply ignore them.

The algorithm which powers "tag --contains" uses the
TMP_MARK and UNINTERESTING bits, but never cleans up after
itself. As a result, stale UNINTERESTING bits may impact
later traversals (like "--merged").
We could fix this by clearing the bits after we're done with
the --contains traversal. That would be enough to fix the
existing problem, but it leaves future developers in a bad
spot: they cannot add other traversals that operate
simultaneously with --contains (e.g., if you wanted to add
"--no-contains" and use both filters at the same time).
Instead, we can use a commit slab to store our cached
results, which will store the bits outside of the commit
structs entirely. This adds an extra level of indirection,
but in my tests (running "git tag --contains HEAD" on
linux.git), there was no measurable slowdown.

In 4ac9006f832 (real_path: have callers use real_pathdup and
strbuf_realpath, 2016-12-12), we changed the xstrdup(real_path())
pattern to use real_pathdup() directly.
The problem with this change is that real_path() calls
strbuf_realpath() with die_on_error = 1 while real_pathdup() calls
it with die_on_error = 0. Meaning that in cases where real_path()
causes Git to die() with an error message, real_pathdup() is silent
and returns NULL instead.
The callers, however, are ill-prepared for that change, as they expect
the return value to be non-NULL (and otherwise the function died
with an appropriate error message).
Fix this by extending real_pathdup()'s signature to accept the
die_on_error flag and simply pass it through to strbuf_realpath(),
and then adjust all callers after a careful audit whether they would
handle NULLs well.

If the local pack-objects of a push fails, we'll tell the
user about it. But one likely cause is that the remote
index-pack stopped reading for some reason (because it
didn't like our input, or encountered another error). In
that case we'd expect the remote to report more details to
us via the "unpack ..." status line. However, the current
code just hangs up completely, and the user never sees it.
Instead, let's call receive_unpack_status(), which will
complain on stderr with whatever reason the remote told us.
Note that if our pack-objects fails because the connection
was severed or the remote just crashed entirely, then our
packet_read_line() call may fail with "the remote end hung
up unexpectedly". That's OK. It's a more accurate
description than what we get now (which is just "some refs
failed to push").
This should be safe from any deadlocks. At the point we make
this call we'll have closed the writing end of the
connection to the server (either by handing it off to
a pack-objects which exited, explicitly in the stateless_rpc
case, or by doing a half-duplex shutdown for a socket). So
there should be no chance that the other side is waiting
for the rest of our pack-objects input.

When the remote tells us that the "unpack" step failed, we
show an error message. However, unless you are familiar with
the internals of send-pack and receive-pack, it was not
clear that this represented an error on the remote side.
Let's re-word to make that more obvious.
Likewise, when we got an unexpected packet from the other
end, we complained with a vague message but did not actually
show the packet. Let's fix that.
And finally, neither message was marked for translation. The
message from the remote probably won't be translated, but

The err_fd descriptor passed to the unpack() function is

encounter an error before handing off the descriptor, we

We fixed an identical deadlock already in 49ecfa13f

Note for curiosity's sake that this bug doesn't trigger on
I32LP64 systems, but does on ILP32 systems. The mistaken
"struct range_set" has two ints and a pointer. That's 16
bytes on LP64, or 12 on ILP32. The correct "struct range"
type has two longs, which is also 16 on LP64, but only 8 on

The idea of the test case "git -p - core.pager is not used from
subdirectory" was to verify that the setup_git_directory() function had
not been called just to obtain the core.pager setting.
However, we are about to fix the early config machinery so that it
*does* work, without messing up the global state.
Once that is done, the core.pager setting *will* be used, even when
running from a subdirectory, and that is a Good Thing.
The intention of that test case, however, was to verify that the
setup_git_directory() function has not run, because it changes global
state such as the current working directory.
To keep that spirit, but fix the incorrect assumption, this patch
replaces that test case by a new one that verifies that the pager is
run in the subdirectory, i.e. that the current working directory has
not been changed at the time the pager is configured and launched, even
if the `rev-parse` command requires a .git/ directory and *will* change
the working directory.

Previously, the git_commit_non_empty_tree function would always pass any
commit with no parents to git-commit-tree, regardless of whether the
tree was nonempty. The new commit would then be recorded in the
filter-branch revision map, and subsequent commits which leave the tree
untouched would be correctly filtered.
With this change, parentless commits with an empty tree are correctly

The existing implementation of range_set_union does not correctly
reallocate memory, leading to a heap overflow when it attempts to union
more than 24 separate line ranges.
For struct range_set *out to grow correctly it must have out->nr set to
the current size of the buffer when it is passed to range_set_grow.
However, the existing implementation of range_set_union only updates
out->nr at the end of the function, meaning that it is always zero
before this. This results in range_set_grow never growing the buffer, as
well as some of the union logic itself being incorrect as !out->nr is
always true.
The reason why 24 is the limit is that the first allocation of size 1
ends up allocating a buffer of size 24 (due to the call to alloc_nr in
ALLOC_GROW). This goes some way to explain why this hasn't been
caught before.
Fix the problem by correctly updating out->nr after reallocating the
range_set. As this results in out->nr containing the same value as the
variable o, replace o with out->nr as well.
Finally, add a new test to help prevent the problem reoccurring in the
future. Thanks to Vegard Nossum for writing the test.

It's tempting to say:
./run v1.0.0 HEAD
to see how we've sped up Git over the years. Unfortunately,
this doesn't quite work because versions of Git prior to
v1.7.0 lack bin-wrappers, so our "run" script doesn't
correctly put them in the PATH.
Worse, it means we silently find whatever other "git" is in
the PATH, and produce test results that have no bearing on
what we asked for.
Let's fallback to the main git directory when bin-wrappers
isn't present. Many modern perf scripts won't run with such

Since 1a0962dee (t/perf: fix regression in testing older
versions of git, 2016-06-22), we point "$MODERN_GIT" to a
copy of git that matches the t/perf script itself, and which
can be used for tasks outside of the actual timings. This is
needed because the setup done by perf scripts keeps moving
forward in time, and may use features that the older
versions of git we are testing do not have.
That commit used $MODERN_GIT to fix a case where we relied
on the relatively recent --git-path option. But if you go
back further still, there are more problems.
Since 7501b5921 (perf: make the tests work in worktrees,
2016-05-13), we use "git -C", but versions of git older than
44e1e4d67 (git: run in a directory given with -C option,
2013-09-09) don't know about "-C". So testing an old version
of git with a new version of t/perf will fail the setup
step.
We can fix this by using $MODERN_GIT during the setup;
there's no need to use the antique version, since it doesn't
affect the timings. Likewise, we'll adjust the "init"
invocation; antique versions of git called this "init-db".

When we parse "git checkout $NAME", we try to interpret
$NAME as a local branch-name. If it is, then we point HEAD
to that branch. Otherwise, we detach the HEAD at whatever
commit $NAME points to.
We do the interpretation by calling strbuf_branchname(), and
then blindly sticking "refs/heads/" on the front. This leads
to nonsense results when expansions like "@{upstream}" or
"@" point to something besides a local branch. We end up
with a local branch name like "refs/heads/origin/master" or
"refs/heads/HEAD".
Normally this has no user-visible effect because those
branches don't exist, and so we fallback to feeding the
result to get_sha1(), which resolves them correctly.
But as the new test in t3204 shows, there are corner cases
where the effect is observable, and we check out the wrong
local branch rather than detaching to the correct one.

This function asks strbuf_branchname() to expand any @-marks
in the branchname, and then we blindly stick refs/heads/ in
front of the result. This is obviously nonsense if the
expansion is "HEAD" or a ref in refs/remotes/.
The most obvious end-user effect is that creating or
renaming a branch with an expansion may have confusing
results (e.g., creating refs/heads/origin/master from
"@{upstream}" when the operation should be disallowed).
We can fix this by telling strbuf_branchname() that we are
only interested in local expansions. Any unexpanded bits are
then fed to check_ref_format(), which either disallows them
(in the case of "@{upstream}") or lets them through
("refs/heads/@" is technically valid, if a bit silly).

The interpret_branch_name() function converts names like
@{-1} and @{upstream} into branch names. The expanded ref
names are not fully qualified, and may be outside of the
refs/heads/ namespace (e.g., "@" expands to "HEAD", and
"@{upstream}" is likely to be in "refs/remotes/").
This is OK for callers like dwim_ref() which are primarily
interested in resolving the resulting name, no matter where
it is. But callers like "git branch" treat the result as a
branch name in refs/heads/. When we expand to a ref outside
that namespace, the results are very confusing (e.g., "git
branch @" tries to create refs/heads/HEAD, which is
nonsense).
Callers can't know from the returned string how the
expansion happened (e.g., did the user really ask for a
branch named "HEAD", or did we do a bogus expansion?). One
fix would be to return some out-parameters describing the
types of expansion that occurred. This has the benefit that
the caller can generate precise error messages ("I
understood @{upstream} to mean origin/master, but that is a
remote tracking branch, so you cannot create it as a local
name").
However, out-parameters make the function interface somewhat
cumbersome. Instead, let's do the opposite: let the caller
tell us which elements to expand. That's easier to pass in,
and none of the callers give more precise error messages
than "@{upstream} isn't a valid branch name" anyway (which
should be sufficient).
The strbuf_branchname() function needs a similar parameter,
as most of the callers access interpret_branch_name()
through it.
We can break the callers down into two groups:
1. Callers that are happy with any kind of ref in the
result. We pass "0" here, so they continue to work
without restrictions. This includes merge_name(),
the reflog handling in add_pending_object_with_path(),
and substitute_branch_name(). This last is what powers
dwim_ref().
2. Callers that have funny corner cases (mostly in
git-branch and git-checkout). These need to make use of
the new parameter, but I've left them as "0" in this
patch, and will address them individually in follow-on
patches.

The return value from strbuf_branchname() is confusing and
useless: it's 0 if the whole name was consumed by an @-mark,
but otherwise is the length of the original name we fed.
No callers actually look at the return value, so let's just
get rid of it.

We generally put docstrings with function declarations,
because it's the callers who need to know how the function
works. Let's do so for interpret_branch_name().

The interpret_branch_name() function takes a ptr/len pair
for the name, but you can pass "0" for "namelen", which will
cause it to check the length with strlen().
However, before we do that auto-namelen magic, we call
interpret_nth_prior_checkout(), which gets fed the bogus
"0". This was broken by 8cd4249c4 (interpret_branch_name:
always respect "namelen" parameter, 2014-01-15). Though to
be fair to that commit, it was broken in the _opposite_
direction before, where we would always treat "name" as a
string even if a length was passed.
You can see the bug with "git log -g @{-1}". That code path
always passes "0", and without this patch it cannot figure
out which branch's reflog to show.
We can fix it by a small reordering of the code.

Callers of diff_populate_filespec() can choose to ask only for the
size of the blob without grabbing the blob data, and the function,
after running lstat() when the filespec points at a working tree
file, returns by copying the value in size field of the stat
structure into the size field of the filespec when this is the case.
However, this short-cut cannot be taken if the contents from the
path needs to go through convert_to_git(), whose resulting real blob
data may be different from what is in the working tree file.
As "git diff --quiet" compares the .size fields of filespec
structures to skip content comparison, this bug manifests as a
false "there are differences" for a file that needs eol conversion,
for example.

When invoked as "git add -i", each menu interactive menu
option prompts the user to select a list of files. This
includes the "patch" option, which gets the list before
starting the hunk-selection loop.
As "git add -p", it behaves differently, and jumps straight
to the hunk selection loop.
Since 0539d5e6d (i18n: add--interactive: mark patch prompt
for translation, 2016-12-14), the "add -i" case mistakenly
jumps to straight to the hunk-selection loop. Prior to that
commit the distinction between the two cases was managed by
the $patch_mode variable. That commit used $patch_mode for
something else, and moved the old meaning to the "$cmd"
variable. But it forgot to update the $patch_mode check
inside patch_update_cmd() which controls the file-list
behavior.
The simplest fix would be to change that line to check $cmd.
But while we're here, let's use a less obscure name for this
flag: $patch_mode_only, a boolean which tells whether we are
in full-interactive mode or only in patch-mode.

Change the gitweb tests to skip when we can't load the Time::HiRes
module.
Gitweb needs this module to work. It has been in perl core since v5.8,
which is the oldest version we support. However CentOS (and perhaps
some other distributions) carve it into its own non-core-perl package
that's not installed along with /usr/bin/perl by default. Without this
we'll hard fail the gitweb tests when trying to load the module.
