f4fd99bf6e Merge branch 'sl/clean-d-ignored-fix'
"git clean -d" used to clean directories that has ignored files,
even though the command should not lose ignored ones without "-x".
"git status --ignored"  did not list ignored and untracked files

fb89888849 dir: hide untracked contents of untracked dirs
When we taught read_directory_recursive() to recurse into untracked
directories in search of ignored files given DIR_SHOW_IGNORED_TOO, that
had the side effect of teaching it to collect the untracked contents of
untracked directories. It doesn't always make sense to return these,
though (we do need them for `clean -d`), so we introduce a flag
(DIR_KEEP_UNTRACKED_CONTENTS) to control whether or not read_directory()
strips dir->entries of the untracked contents of untracked dirs.

We also introduce check_contains() to check if one dir_entry corresponds
to a path which contains the path corresponding to another dir_entry.

This also fixes known breakages in t7061, since status --ignored now
searches untracked directories for ignored files.

b15667bbdc Merge branch 'js/larger-timestamps'
Some platforms have ulong that is smaller than time_t, and our
historical use of ulong for timestamp would mean they cannot
represent some timestamp that the platform allows.  Invent a
separate and dedicated timestamp_t (so that we can distingiuish
timestamps and a vanilla ulongs, which along is already a good
move), and then declare uintmax_t is the type to be used as the
timestamp_t.

cbaf82cc6b receive-pack: verify push options in cert
In commit f6a4e61 ("push: accept push options", 2016-07-14), send-pack
was taught to include push options both within the signed cert (if the
push is a signed push) and outside the signed cert; however,
receive-pack ignores push options within the cert, only handling push
options outside the cert.

Teach receive-pack, in the case that push options are provided for a
signed push, to verify that the push options both within the cert and
outside the cert are consistent.

This sets in stone the requirement that send-pack redundantly send its
push options in 2 places, but I think that this is better than the
alternatives. Sending push options only within the cert is
backwards-incompatible with existing Git servers (which read push
options only from outside the cert), and sending push options only
outside the cert means that the push options are not signed for.

dddbad728c timestamp_t: a new data type for timestamps
Git's source code assumes that unsigned long is at least as precise as
time_t. Which is incorrect, and causes a lot of problems, in particular
where unsigned long is only 32-bit (notably on Windows, even in 64-bit
versions).

So let's just use a more appropriate data type instead. In preparation
for this, we introduce the new `timestamp_t` data type.

By necessity, this is a very, very large patch, as it has to replace all
timestamps' data type in one go.

As we will use a data type that is not necessarily identical to `time_t`,
we need to be very careful to use `time_t` whenever we interact with the
system functions, and `timestamp_t` everywhere else.

8e2c7bef03 fetch-pack: show clearer error message upon ERR
Currently, fetch-pack prints a confusing error message ("expected
ACK/NAK") when the server it's communicating with sends a pkt-line
starting with "ERR".  Replace it with a less confusing error message.

Also update the documentation describing the fetch-pack/upload-pack
protocol (pack-protocol.txt) to indicate that "ERR" can be sent in the
place of "ACK" or "NAK". In practice, this has been done for quite some
time by other Git implementations (e.g. JGit sends "want $id not valid")
and by Git itself (since commit bdb31ea: "upload-pack: report "not our
ref" to client", 2017-02-23) whenever a "want" line references an object
that it does not have. (This is uncommon, but can happen if a repository
is garbage-collected during a negotiation.)

830c912a0e documentation: retire unfinished documentation
When looking for documentation for a specific function, you may be tempted
to run

  git -C Documentation grep index_name_pos

only to find the file technical/api-in-core-index.txt, which doesn't
help for understanding the given function. It would be better to not find
these functions in the documentation, such that people directly dive into
the code instead.

In the previous patches we have documented
* index_name_pos()
* remove_index_entry_at()
* add_[file_]to_index()
in cache.h

We already have documentation for:
* add_index_entry()
* read_index()

Which leaves us with a TODO for:
* cache -> the_index macros
* refresh_index()
* discard_index()
* ie_match_stat() and ie_modified(); how they are different and when to
  use which.
* write_index() that was renamed to write_locked_index
* cache_tree_invalidate_path()
* cache_tree_update()

Subject: clear_delta_base_cache(): don't modify hashmap while iterating

Removing entries while iterating causes fast-import to
access an already-freed `struct packed_git`, leading to
various confusing errors.

What happens is that clear_delta_base_cache() drops the
whole contents of the cache by iterating over the hashmap,
calling release_delta_base_cache() on each entry. That
function removes the item from the hashmap. The hashmap code
may then shrink the table, but the hashmap_iter struct
retains an offset from the old table.

As a result, the next call to hashmap_iter_next() may claim
that the iteration is done, even though some items haven't
been visited.

The only caller of clear_delta_base_cache() is fast-import,
which wants to clear the cache because it is discarding the
packed_git struct for its temporary pack. So by failing to
remove all of the entries, we still have references to the
freed packed_git.

To make things even more confusing, this doesn't seem to
trigger with the test suite, because it depends on
complexities like the size of the hash table, which entries
got cleared, whether we try to access them before they're
evicted from the cache, etc.

So I've been able to identify the problem with large
imports like freebsd's svn import, or a fast-export of
linux.git. But nothing that would be reasonable to run as
part of the normal test suite.

We can fix this easily by iterating over the lru linked list
instead of the hashmap. They both contain the same entries,
and we can use the "safe" variant of the list iterator,
which exists for exactly this case.

Let's also add a warning to the hashmap API documentation to
reduce the chances of getting bit by this again.

34305f7753 pathspec: remove the deprecated get_pathspec function
Now that all callers of the old 'get_pathspec' interface have been
migrated to use the new pathspec struct interface it can be removed
from the codebase.

Since there are no more users of the '_raw' field in the pathspec struct
it can also be removed.  This patch also removes the old functionality
of modifying the const char **argv array that was passed into
parse_pathspec.  Instead the constructed 'match' string (which is a
pathspec element with the prefix prepended) is only stored in its
corresponding pathspec_item entry.

left the reader wondering if it can safely be discarded when it no
longer is necessary.  If the hashmap_entry structure had references
to external resources such as allocated memory or an open file
descriptor, merely free(3)ing the containing structure (when the
caller's structure is on the heap) or letting it go out of scope
(when it is on the stack) would end up leaking the external
resource.

Document that there is no need for hashmap_entry_clear() that
corresponds to hashmap_entry_init() to give the API users a little
bit of peace of mind.

support the "push-options" capability, which when used is a phase directly
after update commands ended by a flush pkt.

Similar to the atomic option, the server capability can be disabled via
the `receive.advertisePushOptions` config variable. While documenting
this, fix a nit in the `receive.advertiseAtomic` wording.

cccf74e2da fetch, upload-pack: --deepen=N extends shallow boundary by N commits
In git-fetch, --depth argument is always relative with the latest
remote refs. This makes it a bit difficult to cover this use case,
where the user wants to make the shallow history, say 3 levels
deeper. It would work if remote refs have not moved yet, but nobody
can guarantee that, especially when that use case is performed a
couple months after the last clone or "git fetch --depth". Also,
modifying shallow boundary using --depth does not work well with
clones created by --since or --not.

This patch fixes that. A new argument --deepen=<N> will add <N> more (*)
parent commits to the current history regardless of where remote refs
are.

Have/Want negotiation is still respected. So if remote refs move, the
server will send two chunks: one between "have" and "want" and another
to extend shallow history. In theory, the client could send no "want"s
in order to get the second chunk only. But the protocol does not allow
that. Either you send no want lines, which means ls-remote; or you
have to send at least one want line that carries deep-relative to the
server..

The main work was done by Dongcan Jiang. I fixed it up here and there.
And of course all the bugs belong to me.

(*) We could even support --deepen=<N> where <N> is negative. In that
case we can cut some history from the shallow clone. This operation
(and --depth=<shorter depth>) does not require interaction with remote
side (and more complicated to implement as a result).

269a7a8316 upload-pack: support define shallow boundary by excluding revisions
This should allow the user to say "create a shallow clone of this branch
after version <some-tag>".

Short refs are accepted and expanded at the server side with expand_ref()
because we cannot expand (unknown) refs from the client side.

Like deepen-since, deepen-not cannot be used with deepen. But deepen-not
can be mixed with deepen-since. The result is exactly how you do the
command "git rev-list --since=... --not ref".

569e554be9 upload-pack: add deepen-since to cut shallow repos based on time
This should allow the user to say "create a shallow clone containing the
work from last year" (once the client side is fixed up, of course).

In theory deepen-since and deepen (aka --depth) can be used together to
draw the shallow boundary (whether it's intersection or union is up to
discussion, but if rev-list is used, it's likely intersection). However,
because deepen goes with a custom commit walker, we can't mix the two
yet.

There are a handful of incorrect "linkgit:<page>[<section>]"
instances in our documentation set.

 * Some have an extra colon after "linkgit:"; fix them by removing
   the extra colon;

 * Some refer to a page outside the Git suite, namely curl(1); fix
   them by using the `curl(1)` that already appears on the same page
   for the same purpose of referring the readers to its manual page.

 * Some spell the name of the page incorrectly, e.g. "rev-list" when
   they mean "git-rev-list"; fix them.

 * Some list the manual section incorrectly; fix them to make sure
   they match what is at the top of the target of the link.

e0070e8bd5 parse-options.c: make OPTION_COUNTUP respect "unspecified" values
OPT_COUNTUP() merely increments the counter upon --option, and resets it
to 0 upon --no-option, which means that there is no "unspecified" value
with which a client can initialize the counter to determine whether or
not --[no]-option was seen at all.

Make OPT_COUNTUP() treat any negative number as an "unspecified" value
to address this shortcoming. In particular, if a client initializes the
counter to -1, then if it is still -1 after parse_options(), then
neither --option nor --no-option was seen; if it is 0, then --no-option
was seen last, and if it is 1 or greater, than --option was seen last.

This change does not affect the behavior of existing clients because
they all use the initial value of 0 (or more).

Note that builtin/clean.c initializes the variable used with
OPT__FORCE (which uses OPT_COUNTUP()) to a negative value, but it is set
to either 0 or 1 by reading the configuration before the code calls
parse_options(), i.e. as far as parse_options() is concerned, the
initial value of the variable is not negative.

To test this behavior, in test-parse-options.c, "verbose" is set to
"unspecified" while quiet is set to 0 which will test the new behavior
with all sets of values.
