From: Jeff Hostetler <jeffhost@microsoft.com>
Refactor add_excludes() to separate the reading of the
exclude file into a buffer and the parsing of the buffer
into exclude_list items.
Add add_excludes_from_blob_to_list() to allow an exclude
file be specified with an OID without assuming a local
worktree or index exists.
Refactor read_skip_worktree_file_from_index() and add
do_read_blob() to eliminate duplication of preliminary
processing of blob contents.

From: Jeff Hostetler <jeffhost@microsoft.com>
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.

From: Jeff Hostetler @ 2017-11-07 19:35 UTC (permalink / raw)
To: git; +Cc: gitster, peff, jonathantanmy, Jeff Hostetler
From: Jeff Hostetler <jeffhost@microsoft.com>
Teach rev-list to use the filtering provided by the
traverse_commit_list_filtered() interface to omit
unwanted objects from the result. This feature is
intended to help with partial clone.
Object filtering is only allowed when one of the "--objects*"
options are used.
When the "--filter-print-omitted" option is used, the omitted
objects are printed at the end. These are marked with a "~".
This option can be combined with "--quiet" to get a list of
just the omitted objects.
Normally, rev-list will stop with an error when there are
missing objects.
When the "--filter-print-missing" option is used, rev-list
will print a list of any missing objects that should have
been included in the output (rather than stopping).
These are marked with a "?".
When the "--filter-ignore-missing" option is used, rev-list
will silently ignore any missing objects and continue without
error.
Add t6112 test.
