Junio C Hamano ca02d3669f Merge branch 'md/list-objects-filter-parse-msgfix'
Make an end-user facing message localizable.

* md/list-objects-filter-parse-msgfix:
  list-objects-filter-options: error is localizeable

Matthew DeVore 5c03bc8b1d list-objects-filter-options: error is localizeable
The "invalid filter-spec" message is user-facing and not a BUG, so make
it localizeable.

For reference, the message appears in this context:

	$ git rev-list --filter=blob:nonse --objects HEAD
	fatal: invalid filter-spec 'blob:nonse'

Christian Couder e693237e2b list-objects-filter: disable 'sparse:path' filters
If someone wants to use as a filter a sparse file that is in the
repository, something like "--filter=sparse:oid=<ref>:<path>"
already works.

So 'sparse:path' is only interesting if the sparse file is not in
the repository. In this case though the current implementation has
a big security issue, as it makes it possible to ask the server to
read any file, like for example /etc/password, and to explore the
filesystem, as well as individual lines of files.

If someone is interested in using a sparse file that is not in the
repository as a filter, then at the minimum a config option, such
as "uploadpack.sparsePathFilter", should be implemented first to
restrict the directory from which the files specified by
'sparse:path' can be read.

For now though, let's just disable 'sparse:path' filters.

Nguyễn Thái Ngọc Duy 5a59a2301f completion: add more parameter value completion
This adds value completion for a couple more paramters. To make it
easier to maintain these hard coded lists, add a comment at the original
list/code to remind people to update git-completion.bash too.

Junio C Hamano 7589e63648 Merge branch 'nd/the-index-final'
The assumption to work on the single "in-core index" instance has
been reduced from the library-ish part of the codebase.

* nd/the-index-final:
  cache.h: flip NO_THE_INDEX_COMPATIBILITY_MACROS switch
  read-cache.c: remove the_* from index_has_changes()
  merge-recursive.c: remove implicit dependency on the_repository
  merge-recursive.c: remove implicit dependency on the_index
  sha1-name.c: remove implicit dependency on the_index
  read-cache.c: replace update_index_if_able with repo_&
  read-cache.c: kill read_index()
  checkout: avoid the_index when possible
  repository.c: replace hold_locked_index() with repo_hold_locked_index()
  notes-utils.c: remove the_repository references
  grep: use grep_opt->repo instead of explict repo argument

Josh Steadmon 87c2d9d310 filter-options: expand scaled numbers
When communicating with a remote server or a subprocess, use
expanded numbers rather than numbers with scaling suffix in the
object filter spec (e.g.  "limit:blob=1k" becomes
"limit:blob=1024").

Update the protocol docs to note that clients should always perform this
expansion, to allow for more compatibility between server
implementations.

Matthew DeVore c813a7c35f list-objects-filter: teach tree:# how to handle >0
Implement positive values for <depth> in the tree:<depth> filter. The
exact semantics are described in Documentation/rev-list-options.txt.

The long-term goal at the end of this is to allow a partial clone to
eagerly fetch an entire directory of files by fetching a tree and
specifying <depth>=1. This, for instance, would make a build operation
fast and convenient. It is fast because the partial clone does not need
to fetch each file individually, and convenient because the user does
not need to supply a sparse-checkout specification.

Another way of considering this feature is as a way to reduce
round-trips, since the client can get any number of levels of
directories in a single request, rather than wait for each level of tree
objects to come back, whose entries are used to construct a new request.

Nguyễn Thái Ngọc Duy 3a7a698e93 sha1-name.c: remove implicit dependency on the_index
This kills the_index dependency in get_oid_with_context() but for
get_oid() and friends, they still assume the_repository (which also
means the_index).

Unfortunately the widespread use of get_oid() will make it hard to
make the conversion now. We probably will add repo_get_oid() at some
point and limit the use of get_oid() in builtin/ instead of forcing
all get_oid() call sites to carry struct repository.

Matthew DeVore bc5975d24f list-objects-filter: implement filter tree:0
Teach list-objects the "tree:0" filter which allows for filtering
out all tree and blob objects (unless other objects are explicitly
specified by the user). The purpose of this patch is to allow smaller
partial clones.

The name of this filter - tree:0 - does not explicitly specify that
it also filters out all blobs, but this should not cause much confusion
because blobs are not at all useful without the trees that refer to
them.

I also considered only:commits as a name, but this is inaccurate because
it suggests that annotated tags are omitted, but actually they are
included.

The name "tree:0" allows later filtering based on depth, i.e. "tree:1"
would filter out all but the root tree and blobs. In order to avoid
confusion between 0 and capital O, the documentation was worded in a
somewhat round-about way that also hints at this future improvement to
the feature.

Matthew DeVore cc0b05a4cc list-objects-filter-options: do not over-strbuf_init
The function gently_parse_list_objects_filter is either called with
errbuf=STRBUF_INIT or errbuf=NULL, but that function calls strbuf_init
when errbuf is not NULL. strbuf_init is only necessary if errbuf
contains garbage, and risks a memory leak if errbuf already has a
non-STRBUF_INIT state. It should be the caller's responsibility to make
sure errbuf is not garbage, since garbage content is easily avoidable
with STRBUF_INIT.

Jeff Hostetler 25ec7bcac0 list-objects: filter objects in traverse_commit_list
Create traverse_commit_list_filtered() and add filtering
interface to allow certain objects to be omitted from the
traversal.

Update traverse_commit_list() to be a wrapper for the above
with a null filter to minimize the number of callers that
needed to be changed.

Object filtering will be used in a future commit by rev-list
and pack-objects for partial clone and fetch to omit unwanted
objects from the result.

traverse_bitmap_commit_list() does not work with filtering.
If a packfile bitmap is present, it will not be used.  It
should be possible to extend such support in the future (at
least to simple filters that do not require object pathnames),
but that is beyond the scope of this patch series.
