[PATCH v4 0/6] Partial clone part 1: object filtering

From: Jeff Hostetler <jeffhost@microsoft.com>

Here is V4 of the list-object filtering, rev-list, and pack-objects.

This version addresses comments on the V3 version series.

This version replaces the code to scan and reject the filter-spec for injection characters with a new hex-encoding technique. The purpose of this is only to guard against injection attacks containing characters like semicolon, quotes, spaces, and etc. when a filter-spec is handed to a subordinate command. It does not eliminate the need for the recipient to validate the contents.

This version also combines the various command line flags for handling missing objects into a single --missing={error,print,allow-any} flag.

Jeff Hostetler (6):
  dir: allow exclusions from blob in addition to file
  oidmap: add oidmap iterator methods
  oidset: add iterator methods to oidset
  list-objects: filter objects in traverse_commit_list
  rev-list: add list-objects filtering support
  pack-objects: add list-objects filtering
