Subject: [PATCH 10/13] rev-list: add list-objects filtering support
Date: Tue, 24 Oct 2017 18:53:29 +0000 [thread overview]
Message-ID: <20171024185332.57261-11-git@jeffhostetler.com> (raw)
In-Reply-To: <20171024185332.57261-1-git@jeffhostetler.com>
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 only enabled when one of the "--objects*"
options are used.
Furthermore, 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.

+--filter=<filter-spec>::
+ Only useful with one of the `--objects*`; omits objects (usually
+ blobs) from the list of printed objects. The '<filter-spec>'
+ may be one of the following:
++
+The form '--filter=blob:none' omits all blobs.
++
+The form '--filter=blob:limit=<n>[kmg]' omits blobs larger than n bytes
+or units. The value may be zero. Special files matching '.git*' are
+alwayse included, regardless of size.
++
+The form '--filter=sparse:oid=<oid-ish>' uses a sparse-checkout
+specification contained in the object (or the object that the expression
+evaluates to) to omit blobs not required by the corresponding sparse
+checkout.
++
+The form '--filter=sparse:path=<path>' similarly uses a sparse-checkout
+specification contained in <path>.
+
+--filter-print-missing::
+ Prints a list of the missing objects for the requested traversal.
+ Object IDs are prefixed with a ``?'' character. The object type
+ is printed after the ID. This may be used with or without any of
