5348021c67 Merge branch 'sb/submodule-recursive-absorb'
When a submodule "A", which has another submodule "B" nested within
it, is "absorbed" into the top-level superproject, the inner
submodule "B" used to be left in a strange state.  The logic to
adjust the .git pointers in these submodules has been corrected.

a272b9e70a urlmatch: allow globbing for the URL host part
The URL matching function computes for two URLs whether they match not.
The match is performed by splitting up the URL into different parts and
then doing an exact comparison with the to-be-matched URL.

The main user of `urlmatch` is the configuration subsystem. It allows to
set certain configurations based on the URL which is being connected to
via keys like `http.<url>.*`. A common use case for this is to set
proxies for only some remotes which match the given URL. Unfortunately,
having exact matches for all parts of the URL can become quite tedious
in some setups. Imagine for example a corporate network where there are
dozens or even hundreds of subdomains, which would have to be configured
individually.

Allow users to write an asterisk '*' in place of any 'host' or
'subdomain' label as part of the host name.  For example,
"http.https://*.example.com.proxy" sets "http.proxy" for all direct
subdomains of "https://example.com", e.g. "https://foo.example.com", but
not "https://foo.bar.example.com".

af99049ca9 urlmatch: include host in urlmatch ranking
In order to be able to rank positive matches by `urlmatch`, we inspect
the path length and user part to decide whether a match is better than
another match. As all other parts are matched exactly between both URLs,
this is the correct thing to do right now.

In the future, though, we want to introduce wild cards for the domain
part. When doing this, it does not make sense anymore to only compare
the path lengths. Instead, we also want to compare the domain lengths to
determine which of both URLs matches the host part more closely.

55cccf4bb3 color_parse_mem: allow empty color spec
Prior to c2f41bf52 (color.c: fix color_parse_mem() with
value_len == 0, 2017-01-19), the empty string was
interpreted as a color "reset". This was an accidental
outcome, and that commit turned it into an error.

However, scripts may pass the empty string as a default
value to "git config --get-color" to disable color when the
value is not defined. The git-add--interactive script does
this. As a result, the script is unusable since c2f41bf52
unless you have color.diff.plain defined (if it is defined,
then we don't parse the empty default at all).

Our test scripts didn't notice the recent breakage because
they run without a terminal, and thus without color. They
never hit this code path at all. And nobody noticed the
original buggy "reset" behavior, because it was effectively
a noop.

Let's fix the code to have an empty color name produce an
empty sequence of color codes. The tests need a few fixups:

  - we'll add a new test in t4026 to cover this case. But
    note that we need to tweak the color() helper. While
    we're there, let's factor out the literal ANSI ESC
    character. Otherwise it makes the diff quite hard to
    read.

  - we'll add a basic sanity-check in t4026 that "git add
    -p" works at all when color is enabled. That would have
    caught this bug, as well as any others that are specific
    to the color code paths.

  - 73c727d69 (log --graph: customize the graph lines with
    config log.graphColors, 2017-01-19) added a test to
    t4202 that checks some "invalid" graph color config.
    Since ",, blue" before yielded only "blue" as valid, and
    now yields "empty, empty, blue", we don't match the
    expected output.

    One way to fix this would be to change the expectation
    to the empty color strings. But that makes the test much
    less interesting, since we show only two graph lines,
    both of which would be colorless.

    Since the empty-string case is now covered by t4026,
    let's remove them entirely here. They're just in the way
    of the primary thing the test is supposed to be
    checking.

949af0684c branch: use ref-filter printing APIs
Port branch.c to use ref-filter APIs for printing. This clears out
most of the code used in branch.c for printing and replaces them with
calls made to the ref-filter library.

Introduce build_format() which gets the format required for printing
of refs. Make amendments to print_ref_list() to reflect these changes.

The strings included in build_format() may not be safely quoted for
inclusion (i.e. it might contain '%' which needs to be escaped with an
additional '%'). Introduce quote_literal_for_format() as a helper
function which takes a string and returns a version of the string that
is safely quoted to be used in the for-each-ref format which is built
in build_format().

Change calc_maxwidth() to also account for the length of HEAD ref, by
calling ref-filter:get_head_discription().

Also change the test in t6040 to reflect the changes.

Before this patch, all cross-prefix symrefs weren't shortened. Since
we're using ref-filter APIs, we shorten all symrefs by default. We also
allow the user to change the format if needed with the introduction of
the '--format' option in the next patch.

the behavior of repositories with worktree.

This commit adds tests that assert the correct behavior in bare

 - If core.logAllRefUpdates is not set, no reflogs should be created
 - If core.logAllRefUpdates is true, reflogs should be created

341fb28621 refs: add option core.logAllRefUpdates = always
When core.logallrefupdates is true, we only create a new reflog for refs
that are under certain well-known hierarchies. The reason is that we
know that some hierarchies (like refs/tags) are not meant to change, and
that unknown hierarchies might not want reflogs at all (e.g., a
hypothetical refs/foo might be meant to change often and drop old
history immediately).

However, sometimes it is useful to override this decision and simply log
for all refs, because the safety and audit trail is more important than
the performance implications of keeping the log around.

This patch introduces a new "always" mode for the core.logallrefupdates
option which will log updates to everything under refs/, regardless
where in the hierarchy it is (we still will not log things like
ORIG_HEAD and FETCH_HEAD, which are known to be transient).

b26d87f2da merge-recursive: make "CONFLICT (rename/delete)" message show both paths
The current message printed by "git merge-recursive" for a rename/delete
conflict is like this:

CONFLICT (rename/delete): new-path deleted in HEAD and renamed in
other-branch. Version other-branch of new-path left in tree.

To be more helpful, the message should show both paths of the rename and
state that the deletion occurred at the old path, not the new path.  So
change the message to the following format:

CONFLICT (rename/delete): old-path deleted in HEAD and renamed to
new-path in other-branch. Version other-branch of new-path left in tree.

Since this doubles the number of cases in handle_change_delete (modify vs.
rename), refactor the code to halve the number of cases again by merging the
cases where o->branch1 has the change and o->branch2 has the delete with the
cases that are the other way around.

Also add a simple test of the new conflict message.

7dbabbbebe pack-objects: enforce --depth limit in reused deltas
Since 898b14c (pack-objects: rework check_delta_limit usage,
2007-04-16), we check the delta depth limit only when
figuring out whether we should make a new delta. We don't
consider it at all when reusing deltas, which means that
packing once with --depth=250, and then again with
--depth=50, the second pack may still contain chains larger
than 50.

This is generally considered a feature, as the results of
earlier high-depth repacks are carried forward, used for
serving fetches, etc. However, since we started using
cross-pack deltas in c9af708b1 (pack-objects: use mru list
when iterating over packs, 2016-08-11), we are no longer
bounded by the length of an existing delta chain in a single
pack.

Here's one particular pathological case: a sequence of N
packs, each with 2 objects, the base of which is stored as a
delta in a previous pack. If we chain all the deltas
together, we have a cycle of length N. We break the cycle,
but the tip delta is still at depth N-1.

This is less unlikely than it might sound. See the included
test for a reconstruction based on real-world actions.  I
ran into such a case in the wild, where a client was rapidly
sending packs, and we had accumulated 10,000 before doing a
server-side repack.  The pack that "git repack" tried to
generate had a very deep chain, which caused pack-objects to
run out of stack space in the recursive write_one().

This patch bounds the length of delta chains in the output
pack based on --depth, regardless of whether they are caused
by cross-pack deltas or existed in the input packs. This
fixes the problem, but does have two possible downsides:

  1. High-depth aggressive repacks followed by "normal"
     repacks will throw away the high-depth chains.

     In the long run this is probably OK; investigation
     showed that high-depth repacks aren't actually
     beneficial, and we dropped the aggressive depth default
     to match the normal case in 07e7dbf0d (gc: default
     aggressive depth to 50, 2016-08-11).

  2. If you really do want to store high-depth deltas on
     disk, they may be discarded and new delta computed when
     serving a fetch, unless you set pack.depth to match
     your high-depth size.

The implementation uses the existing search for delta
cycles.  That lets us compute the depth of any node based on
the depth of its base, because we know the base is DFS_DONE
by the time we look at it (modulo any cycles in the graph,
but we know there cannot be any because we break them as we
see them).

There is some subtlety worth mentioning, though. We record
the depth of each object as we compute it. It might seem
like we could save the per-object storage space by just
keeping track of the depth of our traversal (i.e., have
break_delta_chains() report how deep it went). But we may
visit an object through multiple delta paths, and on
subsequent paths we want to know its depth immediately,
without having to walk back down to its final base (doing so
would make our graph walk quadratic rather than linear).

Likewise, one could try to record the depth not from the
base, but from our starting point (i.e., start
recursion_depth at 0, and pass "recursion_depth + 1" to each
invocation of break_delta_chains()). And then when
recursion_depth gets too big, we know that we must cut the
delta chain.  But that technique is wrong if we do not visit
the nodes in topological order. In a chain A->B->C, it
if we visit "C", then "B", then "A", we will never recurse
deeper than 1 link (because we see at each node that we have
already visited it).

d98b2c5fce test-lib: on FreeBSD, look for unzip(1) in /usr/local/bin/
Eric Wong reported that while FreeBSD has a /usr/bin/unzip, it uses
different semantics from those that are needed by Git's tests: When
passing the -a option to Info-Zip, it heeds the text attribute of the
.zip file's central directory, while FreeBSD's unzip ignores that
attribute.

The common work-around is to install Info-Zip on FreeBSD, into

93a04bb105 t/Makefile: add a rule to re-run previously-failed tests
This patch automates the process of determining which tests failed
previously and re-running them.

While developing patch series, it is a good practice to run the test
suite from time to time, just to make sure that obvious bugs are caught
early.  With complex patch series, it is common to run `make -j15 -k
test`, i.e.  run the tests in parallel and *not* stop at the first
failing test but continue. This has the advantage of identifying
possibly multiple problems in one big test run.

It is particularly important to reduce the turn-around time thusly on
Windows, where the test suite spends 45 minutes on the computer on which
this patch was developed.

It is the most convenient way to determine which tests failed after
running the entire test suite, in parallel, to look for left-over "trash
directory.t*" subdirectories in the t/ subdirectory. However, those
directories might live outside t/ when overridden using the
--root=<directory> option, to which the Makefile has no access. The next
best method is to grep explicitly for failed tests in the test-results/
directory, which the Makefile *can* access.

Please note that the often-recommended `prove` tool requires Perl, and
that opens a whole new can of worms on Windows. As no native Windows Perl
comes with Subversion bindings, we have to use a Perl in Git for Windows
that uses the POSIX emulation layer named MSYS2 (which is a portable
version of Cygwin). When using this emulation layer under stress, e.g.
when running massively-parallel tests, unexplicable crashes occur quite
frequently, and instead of having a solution to the original problem, the
developer now has an additional, quite huge problem. For that reason, this
developer rejected `prove` as a solution and went with this patch instead.

e7b37caf4f submodule update: run custom update script for initial populating as well
In 1b4735d9f3 (submodule: no [--merge|--rebase] when newly cloned,
2011-02-17), all actions were defaulted to checkout for populating
a submodule initially, because merging or rebasing makes no sense
in that situation.

Other commands however do make sense, such as the custom command
that was added later (6cb5728c43, submodule update: allow custom

I am unsure about the "none" command, as I can see an initial
checkout there as a useful thing. On the other hand going strictly
by our own documentation, we should do nothing in case of "none"
as well, because the user asked for it.

ec9629b3b9 submodule absorbing: fix worktree/gitdir pointers recursively for non-moves
Consider having a submodule 'sub' and a nested submodule at 'sub/nested'.
When nested is already absorbed into sub, but sub is not absorbed into
its superproject, then we need to fixup the gitfile and core.worktree
setting for 'nested' when absorbing 'sub', but we do not need to move
its git dir around.

Previously 'nested's gitfile contained "gitdir: ../.git/modules/nested";
it has to be corrected to "gitdir: ../../.git/modules/sub1/modules/nested".

An alternative I considered to do this work lazily, i.e. when resolving
"../.git/modules/nested", we would notice the ".git" being a gitfile
linking to another path.  That seemed to be robuster by design, but harder
to get the implementation right.  Maybe we have to do that anyway once we
try to have submodules and worktrees working nicely together, but for now
just produce 'correct' (i.e. direct) pointers.

e9d9a8a4d2 connect: handle putty/plink also in GIT_SSH_COMMAND
Git for Windows has special support for the popular SSH client PuTTY:
when using PuTTY's non-interactive version ("plink.exe"), we use the -P
option to specify the port rather than OpenSSH's -p option. TortoiseGit
ships with its own, forked version of plink.exe, that adds support for
the -batch option, and for good measure we special-case that, too.

However, this special-casing of PuTTY only covers the case where the
user overrides the SSH command via the environment variable GIT_SSH
(which allows specifying the name of the executable), not
GIT_SSH_COMMAND (which allows specifying a full command, including
additional command-line options).

When users want to pass any additional arguments to (Tortoise-)Plink,
such as setting a private key, they are required to either use a shell
script named plink or tortoiseplink or duplicate the logic that is
already in Git for passing the correct style of command line arguments,
which can be difficult, error prone and annoying to get right.

This patch simply reuses the existing logic and expands it to cover
GIT_SSH_COMMAND, too.

Note: it may look a little heavy-handed to duplicate the entire
command-line and then split it, only to extract the name of the
executable. However, this is not a performance-critical code path, and
the code is much more readable this way.

3d415425c7 unpack-trees: support super-prefix option
In the future we want to support working tree operations within submodules,
e.g. "git checkout --recurse-submodules", which will update the submodule
to the commit as recorded in its superproject. In the submodule the
unpack-tree operation is carried out as usual, but the reporting to the
user needs to prefix any path with the superproject. The mechanism for
this is the super-prefix. (see 74866d757, git: make super-prefix option)

Add support for the super-prefix option for commands that unpack trees
by wrapping any path output in unpacking trees in the newly introduced
super_prefixed function. This new function prefixes any path with the
super-prefix if there is one.  Assuming the submodule case doesn't happen
in the majority of the cases, we'd want to have a fast behavior for no
super prefix, i.e. no reallocation/copying, but just returning path.

Another aspect of introducing the `super_prefixed` function is to consider
who owns the memory and if this is the right place where the path gets
modified. As the super prefix ought to change the output behavior only and
not the actual unpack tree part, it is fine to be that late in the line.
As we get passed in 'const char *path', we cannot change the path itself,
which means in case of a super prefix we have to copy over the path.
We need two static buffers in that function as the error messages
contain at most two paths.

For testing purposes enable it in read-tree, which has no output
of paths other than an unpack-trees.c. These are all converted in
this patch.

c20d4d702f t1450: use "mv -f" within loose object directory
The loose objects are created with mode 0444. That doesn't
prevent them being overwritten by rename(), but some
versions of "mv" will be extra careful and prompt the user,
even without "-i".

Reportedly macOS does this, at least in the Travis builds.
The prompt reads from /dev/null, defaulting to "no", and the
object isn't moved. Then to make matters even more
interesting, it still returns "0" and the rest of the test
proceeds, but with a broken setup.

We can work around it by using "mv -f" to override the
prompt. This should work as it's already used in t5504 for
the same purpose.

e459b073fb remote rename: more carefully determine whether a remote is configured
One of the really nice features of the ~/.gitconfig file is that users
can override defaults by their own preferred settings for all of their
repositories.

One such default that some users like to override is whether the
"origin" remote gets auto-pruned or not. The user would simply call

	git config --global remote.origin.prune true

and from now on all "origin" remotes would be pruned automatically when
fetching into the local repository.

There is just one catch: now Git thinks that the "origin" remote is
configured, even if the repository config has no [remote "origin"]
section at all, as it does not realize that the "prune" setting was
configured globally and that there really is no "origin" remote
configured in this repository.

That is a problem e.g. when renaming a remote to a new name, when Git
may be fooled into thinking that there is already a remote of that new
name.

Let's fix this by paying more attention to *where* the remote settings
came from: if they are configured in the local repository config, we
must not overwrite them. If they were configured elsewhere, we cannot
overwrite them to begin with, as we only write the repository config.

There is only one caller of remote_is_configured() (in `git fetch`) that
may want to take remotes into account even if they were configured
outside the repository config; all other callers essentially try to
prevent the Git command from overwriting settings in the repository
config.

To accommodate that fact, the remote_is_configured() function now
requires a parameter that states whether the caller is interested in all
remotes, or only in those that were configured in the repository config.

Many thanks to Jeff King whose tireless review helped with settling for
nothing less than the current strategy.

c3271a0e47 fsck: do not fallback "git fsck <bogus>" to "git fsck"
Since fsck tries to continue as much as it can after seeing
an error, we still do the reachability check even if some
heads we were given on the command-line are bogus. But if
_none_ of the heads is is valid, we fallback to checking all
refs and the index, which is not what the user asked for at
all.

Instead of checking "heads", the number of successful heads
we got, check "argc" (which we know only has non-options in
it, because parse_options removed the others).
